Years fly by, and time flies by. Looking back, 20xx has been both bitter and sweet. In the past year, our machine shop has taken every day seriously with full enthusiasm. We work together, overcome difficulties, and contribute silently to the development of the company with perseverance.
The ancients said: Taking history as a mirror, we can know the ups and downs. Looking back on the past year, we shouldered the responsibilities and responsibilities. Although the steps were heavy, we gradually became more and more steady. Of course, the achievements belong to the past, and facing the new During the journey, we have to reflect more on the shortcomings in our work.
In terms of production site management: the production site management of each position is relatively chaotic, the environmental sanitation, equipment sanitation, and personnel hygiene are poor, and the awareness of cleaning after operating machine tools is weak. On-site management should be strengthened and management measures should be strengthened. Arrange special personnel to conduct supervision and inspection. In terms of personnel management: lack of quality concept and cost concept, it is recommended to implement a method of parallel production and quality based on the piece-rate system in 2016, that is, how many materials are received, how many finished products are produced, and the finished product qualification rate is strictly controlled. In terms of efficiency improvement: I call on all colleagues to display their job spirit, base themselves on the workshop, actively make suggestions, work together, and optimize the operating procedures of each position. As long as it is a method that can improve efficiency, we hope that the company can actively adopt, promote and provide corresponding material rewards. In terms of improving the mechanism and system: Optimize the performance appraisal method, based on quality, efficiency, and cost. Those who fail to meet the qualification line must be appropriately punished, and those with high qualification rates must also be rewarded accordingly.
In terms of production safety: It is recommended to take precautions in advance and move the checkpoint forward. As employees, we need to seek pressure on ourselves, dare to expose our scandals, find key people and key positions at work, focus on control, and highlight the prevention-oriented policy to achieve zero accidents. , the purpose of zero safety hazards.
In terms of labor discipline: Strictly implement the relevant attendance system regulations, and have zero tolerance for tardiness, leaving early, absenteeism, off-duty and other behaviors. It is recommended to issue warnings and criticisms to those who skip work for non-work reasons, strengthen supervision on the wearing of labor protection supplies, and Those who cause property damage due to illegal operations shall also be punished accordingly.
From a new starting point, our machine shop will adhere to the fine style of being able to endure hardships, not complaining, being responsible, and having strong skills, and be the vanguard on the company's development path. As the new year approaches, once again, on behalf of the machine shop, I Processing workshop, I wish you all a prosperous new year, a silver tree with auspicious flowers and fruitful fruits. Mechanical monthly work summary 3
Work completed in January and May
1. On April 28, the release of the company's quality system documents "Quality Manual" and "Procedure Documents" was completed, marking Our company's TS16949 quality system implementation has entered the second stage of formal operation. At this stage, every relevant department in the company must continuously improve quality records and compile statistics on the work/process performance indicators of relevant departments to lay the foundation for the next step of the company's internal audit.
2. With the cooperation of the General Management Department, nearly half a month was used to organize the company's logistics management personnel to conduct system document training in response to the lack of TS16949 quality management system knowledge and effective working methods in each department. It mainly enables grassroots managers to understand the company's quality objectives and quality policies, and implement them in their daily work; combined with the actual work of each department, it focuses on explaining department responsibilities and work processes, as well as the quality records and work interfaces that each department needs to leave during its work process. , and requires the formation of closed-loop management. Improve overall quality awareness and the quality management level of grassroots managers.
3. According to the requirements of the standard implementation promotion plan, improve/design/produce the company's quality record form and improve the quality record list. There are a total of more than 160 quality record forms (documents). Except for 8 types that require mimeographing, all the others have been issued. In June, each department gradually adopted forms to record work processes in accordance with standard requirements/procedure documents in actual work, eliminating previous work that was communicated verbally and subsequent follow-up verification defects. It will surely improve all aspects of the company's work.
4. Guide each department to improve its department’s quality records in accordance with the TS16949 quality management system. Supervise each department to designate system operation specialists to be responsible for the department's system operation and assist department leaders in improving department work. Establish a regular meeting system to regularly check the operating status of the company's system every week, and inform incentives at regular group meetings; at the same time, arrange next steps. It is hoped that through such activities, the company's standard implementation process will be accelerated and management improvement will be promoted.
2. Existing deficiencies and problems found
1. The product failure rate remains high: the following improvement measures are recommended
A. Conduct professional training on all quality personnel Skills, quality awareness, work responsibility and other training to enhance the centripetal force of inspectors.
B. Establish supplier quality management and performance appraisal procedures to increase the frequency of inspections and strictly control the quality of incoming materials.
C. Collect statistics on each quality control point, find the real cause, and make complete improvements.
D. Organize various departments to set up quality improvement groups (qc groups), especially to strengthen machine control, which can conduct first-end comparisons, small batch trial production, and improve product qualification rates.
2. There is a lack of teamwork spirit among various departments, the grassroots management is passive and lazy, lacks work passion, and production efficiency is low.
A. Improve the employee performance appraisal system. (Can be divided into three levels: A/B/C)
B. Organize internal team activities within the company.
Use the off-season to organize management training (internal/external/film and television materials)
C. Specially strengthen training courses on team spirit and implement a reward and punishment system appropriately for performance at work
D . According to the process rhythm of each process, professionals reasonably arrange the production process and implement output target management.
3. Work plan for next month
1. Assist in internal audit training and prepare internal audit checklist before training (process audit checklist, product audit inspection, internal audit inspection Table) provided for teacher review.
2. Strengthen the daily work management within the Quality Assurance Department, fully mobilize the enthusiasm of employees, and avoid internal conflicts. Change the past problem of inspectors often being in the office, enhance the awareness of active cooperation, and prepare to eliminate the last place or reduce the coefficient of the last place. Strengthen process control, change the past problems of mainly passive assessment of the process inspection process (with the occurrence of scrap assessment), less active assessment, and poor quality awareness of employees, and improve product quality.

1. Work projects and completion status
Before the internship, the company organized some theoretical training, including safety knowledge. Theoretical training mainly allows us to quickly and comprehensively understand the company's general outline and production content.
The internship at this stage is mainly in the metalworking workshop of the bridge box factory. First, the leader arranged for me to work on the CNC lathe in the metalworking workshop based on my hobbies and characteristics. I learned relevant CNC knowledge from Master Wang Xinghong. The lathe involved was HTC4596a.
Usually, while helping the master, I also learn some programming knowledge from him (mainly in turning), and the master patiently answers my questions. As time goes by, I have gone from knowing nothing about programming to now being able to understand related programs and simple programming. Helping Acting Director Dai Qiang to handle relevant documents gave me a certain understanding of the relevant personnel in the entire workshop, and further improved my use of Excel. The results of this learning stage are inseparable from the guidance of the two masters.
With the deepening of my study, I also exposed some problems, many of which I did not see thoroughly enough. I am grateful to the teachers for their teachings.
Generally speaking, the purpose of this internship in the workshop has been achieved. I have a certain understanding of the main equipment of the entire axle box factory, the two CNC lathes used by the master and the parts they produce. With a new understanding.
2. Internship Harvest
1. Product structure, working principle and main parameters
The main products of the axle box factory are various gearboxes and torque converters , wet bridge.
As the name suggests, the function of the torque converter is to change the torque. Shifting is a matter of the gearbox, and the axle transmits power.
There are two common loader torque converters: a single turbine for fixed-axis gearboxes, and a twin-turbinone for planetary carrier gearboxes. The principle is simply like two electric fans standing close to each other. One is powered and rotates to blow the wind to the other, thereby driving the other to rotate. The powered one is equivalent to the pump impeller (the pump impeller is driven directly by the engine), and the other one is equivalent to the turbine.
When the pump impeller rotates, the transmission oil rushes toward the turbine at high speed, thereby driving the turbine to rotate. The turbine rotates and outputs power to the gearbox.
The working principle of the torque converter is that the torque converter pump wheel directly connected to the engine rotates, stirring the transmission oil in the torque converter and moving according to certain rules. There is a fixed position in the middle of the hydraulic torque converter. When the liquid passes through the guide wheel, it goes through various complex changes and impacts the output turbine, driving the turbine to rotate to increase the torque. When the torque is increased, the output speed of the turbine will decrease. For a torque converter, the main parameters are the transmission ratio and the torque ratio. For torque converter manufacturers, they generally provide a thousand-rpm torque to match the engine and the torque converter. Wet drive axle refers to wet brake drive axle. The brake pads are installed in the wheel reducer or main reducer and are soaked in gear oil.
2. Models, specifications and uses of the main equipment in the workshop
There are many main equipment in the workshop, mainly divided into lathes, grinders, drilling machines, milling machines, gear hobbing, gear shaping, etc. wait. At the same time, there are many handling tools in the workshop, such as pallet trucks, hand forklifts, battery forklifts, internal combustion forklifts, etc. These machine tools and handling tools have greatly improved the production efficiency of front-line employees.
Main components of CNC lathes:
①Main transmission system and spindle parts: make the tool or workpiece produce cutting motion;
②Feeding system: make the workpiece Or the tool generates feed motion and achieves positioning;
③ Basic parts such as bed, column, slide, workbench;
④ Other auxiliary devices, such as hydraulic, pneumatic, lubrication , cutting fluid and other systems and devices.
Here is a brief introduction to CAK6763, a CNC horizontal lathe with a maximum working diameter of 630mm and a maximum stroke of 1500mm. It is produced by Dalian Second Machine Tool Factory. It is mainly used for turning some rotary parts, such as first-speed pistons and direct-speed lathes. Pistons and more. For forklifts, for example, the pallet handling forklift TE30 has a dead weight of 700Kg, a rated load of 3000Kg, a rated power of 12KW, a rated voltage of 24V, a load center distance of 600mm, a lifting height of 200mm, and a battery weight of 180Kg. This kind of forklift is mainly used to transport parts in production and save time. Even if various process equipment are not in the same place, the effect of assembly line production can still be achieved.
There are also many important equipment in the workshop, such as the CNC double-column coordinate boring machine TK42100/2 for tooling, several planet carrier lines, bridge housing lines, gear housing lines, etc. I will not list them one by one here. .
3. Names and drawing numbers of main parts
Here are some parts processed by the master during my internship next to him, such as ZL50E-3 output shaft gear (drawing number 50A0011, Original code Z5EⅡ030000001), CG932H driven gear, ZL30B-II first-stage turbine hub (Drawing No. Z3BⅡ020XX0001), second-speed piston ZL30B-II (Drawing No. Z3BⅡ030000019), etc.
4. Main parts processing technology
Here is the process of CG932H passive gear:
①Material blanking 20CrMnTi (outsourcing)
②Forging and forging billet (outsourced)
③Hot normalizing treatment (outsourced)
④Rough turning of all parts to "Process Drawing" 1 (outsourced)
⑤Thermal stress relief annealing, see "Heat Treatment Process Card Number"
⑥Lathe a, clip the outer circle of the right end, and finish turning the parts, inner holes and chamfers of the left end to the "Process Drawings" 》2
b. Clamp the outer circle of the left end, finish turning the right end of each part, and chamfer to "Process Drawing" 2
⑦ The tooth is supported by the left end, and pull the spline to Figure L5560C0. 05
⑧The teeth are positioned with internal splines, hobbing to Wk100.020, Fr0.09, Fw0.05, and deburred
⑨Thermal carburizing and quenching treatment, see "Heat Treatment Process Card number》
0.30 ⑩ Grind a, the calibration spline and its left end face runout ≤ 0.05, grind the inner hole to 60.230.28, the roughness is less than 1.6 microns, grind the left end face to the picture
b. Using the left end face as support, grind the right end face of the spline to the figure as shown in the figure. The remaining two steps are teeth. Grind the upper tooling to the figure as shown in the figure; clamp and assemble, waiting for assembly.
My master is mainly responsible for the turning part, first rough turning and then finish turning. The CNC lathe HTC4596a clamp uses a three-jaw chuck. The clamping force of the chuck is hydraulically driven, approximately between 10 and 15MPa, to prevent parts from deforming due to excessive clamping force. The detection methods mainly use vernier calipers, micrometers and dial indicators. Mainly detects the diameter, distance, etc. of parts.
3. Work-related improvement suggestions
During work, since the machine tool the master operates is a CNC lathe, I still found some problems in this aspect. The first is programming. Every time the master processes a new part, he will spend a certain amount of time programming, or modifying the program. What I want to say is is there a possibility for various machine tools to process some parts permanently, eliminating the need for programming? time, because sometimes a programming can take almost an hour, and it can also cause certain losses when errors occur. Also, if parts can be produced on an assembly line like the axle housing line over there, the efficiency will definitely be greatly improved. The specific measures are to adjust the position of the machine tool and reasonably arrange the production process of the machine tool. In addition, during the processing process, through communication with the master, I found that the reason why some products were unqualified was because the blanks were unqualified. Just imagine, if the blank is unqualified, will the processed parts be qualified? But this processing process not only wastes time, but also wastes manpower and material resources. So I think the company should take care of this aspect.
Also, the factory is currently planning production drawings. I think it’s very good. Only when the drawings are completed can employees’ production efficiency be improved. To put it bluntly, more money can be earned per unit of time and employees will be more motivated. will improve, and the factory's resources can be used rationally. This is a win-win result. Moreover, once the drawings are completed, the waste products that will follow will definitely be reduced. I hope the company can continue to do this and reasonably plan the drawings of various processed parts.
4. Reflections on personal growth
There are still many problems encountered at work. The first is CNC programming. Since some codes of various equipment have different meanings, I want to completely understand them. It’s still difficult to understand.
Another problem is that the master has too many holidays, which makes it difficult for me to communicate with the master about some numerical control problems. It has been more than a month since the internship, and the master is about to take a month's leave, so I hope the factory can make reasonable plans in this regard.
I have basically encountered no difficulties in my life. The houses provided by the company are not only close to the workplace, but also very cheap. Thanks to the factory and the leaders in charge.
In the blink of an eye, I have been working for almost 2 months. I call it work, but in fact I am here to learn. I think there are few companies that do better than Chenggong in this regard. Only by laying a good foundation can we succeed. Have better work ability, complete the work, and help you succeed. It is true. Thank you for the opportunity provided by the leader. During this study period, I learned a lot, not only various knowledge, but also the principles of life. In terms of dealing with people, I have made great progress. Because I often travel in the factory, I also fell in love with dealing with the masters, fell in love with asking why, and thanked the masters for their selfless help.
In just one month, I feel that I really learned more than before. The most important thing is that in this kind of situation, I really learned how to deal with people and learned survival skills.
Thank you to everyone who has helped me and cared about me, and thank you to the leaders. Mechanical monthly work summary 5
