Inner city communication cable: HYA HYAC HYAT
Today, as communications can become increasingly powerful, communication quality also strives to improve. As a manufacturer of communication cables, if you want to remain invincible, the quality of your products must have strict requirements. Therefore, in production, every production link is the key to quality problems. Therefore, there are many links that need to be paid attention to and studied. It is impossible to list them all here. Here is a brief analysis of the following issues based on my personal experience.
In the series connection process, the most important issue is the wire diameter control of the copper wire. For example, our company controls the conductor diameter of a single copper wire with a diameter of 0.4 mm to 0.385~0.390mm. Control of the outer diameter of the insulation Within 0.67~0.69 mm. Therefore, in order to obtain such high-precision technical indicators, every factor that affects the wire diameter must be considered, otherwise the products produced will be unqualified.
The most important factor affecting the wire diameter is the outlet drawing die, which is the decisive factor in producing copper wires of different wire diameters. The annealing voltage, traction force and take-up tension of the annealing cabinet are all factors that affect the conductor wire diameter. If there is a problem with the machine equipment, it may also affect the wire diameter, such as damage to the outlet mold or uneven outlet edges.
The determination of the outer diameter of the insulation is mainly related to the glue output of the extruder and the speed of the take-up. The size of the insulation outer diameter is proportional to the glue output of the extruder and is proportional to the take-up frame. is inversely proportional to the take-up speed. The amount of glue output is proportional to the speed of the screw. However, after setting the wire diameter of the product on the caliper, the caliper compares the actual product outer diameter with the ideal value and automatically feeds it back to the extruder and shrinker. The wire frame can play a role in fine-tuning the speed of the machine. It is also related to the temperature adjustment of each zone. If the temperature of each zone is not properly controlled, the insulation material extruded by the extruder may be too thin and difficult to control, or the sheathing material may be burned and the material may not be discharged smoothly. These are all reasons for the unqualified wire diameter. The twisting process seems simple. But its role cannot be ignored. It not only twists two single wires of different color spectrums together to form a loop, but more importantly, it uses different pitches for different color spectrums (selected through rigorous calculations). After twisting, It can eliminate electromagnetic interference between loops and crosstalk between line pairs. The requirements of the twisting process directly affect the electrical performance of the cable, which is what we should pay special attention to in the production of high-quality communication components. Therefore, the twisting process is our seemingly simplest process, but it has important technical indicators.
The sheathing process is the last process in the production of communication cables, and it is also the most critical process. If the operation is not careful, the consequences will be huge, and not only will the employees’ labor effectiveness not be reflected, , and it causes a waste of expensive raw materials and resources, increases the cost of the company's products, and reduces the company's efficiency. Therefore, once the sheathing process is started, it cannot be stopped and the continuity of production must be ensured. The core technology of the sheathing process lies in the extruder. Most of our company's production of local communication cables uses an extruder with an aspect ratio of 25:1. The temperature of each zone of the extruder is controlled and the mold core and mold sleeve are selected. is the key. If the temperature is improperly controlled, the melting of the sheath material will fail. If the sheath material is burnt, it may clog the extruder head, or the sheath may be eccentric due to the sheath material being too soft. The discharge must be in line with the take-up line. Speed ??sync. The selection and installation of the mold core and mold sleeve should be accurately calculated and determined according to the specifications of the cable. It should not be large or small. The installation center of the mold core and mold sleeve must be strictly on the same horizontal line to ensure the eccentricity of the sheath.
In quality inspection, the most important thing is seriousness and responsibility. This is an essential quality for quality inspection staff. Use a spiral micrometer (micrometer) to measure the conductor outer diameter and insulation outer diameter of a single wire. When measuring diameter, under the premise of correct measurement, if you want to get correct results, you must ensure that the prototype of the measurement object is retained. Do not pull the single wire with force, let alone use too much force on the spiral micrometer when measuring, otherwise the error of the measurement value will increase. , the measurement results will be invalid. In back-end testing, proficiency is the key. Especially when measuring continuity and DC resistance of wires, only proficiency can improve work efficiency and ensure accurate measurements. Our company also has a DCM fully automatic tester. The DCM function can measure the primary and secondary parameters of the cable at one time. Measurable parameters include: attenuation, crosstalk, capacitance imbalance, capacitance, resistance, resistance imbalance, etc.
5. Internship experience
Time flies, and in a blink of an eye, the one-month internship is coming to an end. As for my overall feeling, I can sum it up in four words: "relaxed and solid". During this month, I was arranged to mainly focus on free learning, and I learned a lot about production technology. As a new college student, I have also initially entered the society and integrated into XXXX. When I come here, I feel very happy every day. Among them, I don’t have the so-called intrigues for material interests after entering the society. , intrigues. To be more precise, we have entered a team with harmonious relationships, unity and struggle, and a positive team. Everyone has a smile on every busy figure. There is a manager with a bold personality, dedicated and responsible boss, a confident and stable director, a humorous and joking master Zhang Liwei, and even more enthusiastic and helpful colleagues. Whenever I encounter problems in my work and study, they can give me patient and detailed explanations. When I was learning about quality inspection, my colleagues taught me patiently with the attitude of a senior fellow student.
The issues to pay attention to during measurement, measurement methods, use of instruments, and process standard requirements were all explained to me in detail one by one. Although I talk a lot and am not good at expressing myself, I sincerely thank them. Even the master workers in the workshop tolerated my negligence and mistakes when I first arrived. During a cabling process, I helped a master worker thread the wires. Due to my carelessness, the machine was disconnected several times. During the wiring process, the master They were not angry, and patiently explained to me the reasons for the disconnection, the characteristics of poor performance due to aging and damage of the machine, and the best way to deal with it. Everyone's concern is undoubtedly the greatest motivation for me, a learner who doesn't like to ask questions. Now I can say: I made the right choice by choosing XXXX.
During this one-month internship in the workshop, I always followed the normal work and rest schedule. The first impression it gave me was that it gave me a sense of maturity and gave me an extra responsibility. Driven by this sense of responsibility, I have a stronger desire to learn and understand the company's production links. It also strengthened my expectations and yearning for work. When I thought about leaving the company and going back to school for a while, I felt a feeling that was hard to let go. The feelings I received from my work deepened my understanding of my previous work. No matter what job you do, you must have good professional ethics and excellent professional skills. No matter how simple the work is, there is always a secret in it, so every small link cannot be underestimated.
After one month of internship. I learned a lot and better understood the true meaning of work. I have the confidence to be a technical worker and an excellent XX person. ;
