According to the structure, it can be divided into two categories:
1, open CNC punch: C-shaped structure, with one side open. Advantages: low cost, convenient workpiece loading and unloading, and convenient large-scale sheet metal processing. Defect: the maximum tonnage of this station is only 35 tons, and the accuracy decreases when it exceeds 35 tons.
2. Closed CNC punch press: The mechanism is O-shaped with no open face. Advantages: it can build a high tonnage of more than 35 tons and has good stability. Suitable for high-precision sheet metal processing. Disadvantages: the cost is higher than that of open CNC punch, and the loading and unloading must be carried out from the left and right sides.
According to the working stamping method:
1. Mechanical transmission: the impact head is driven to punch holes through the rotational inertia of the flywheel. Advantages: low cost and easy maintenance; Disadvantages: loud noise and limited tonnage.
2. Hydraulic transmission: the motor of the hydraulic cylinder drives the striking head for stamping. Advantages: low noise and large tonnage; Disadvantages: the cost is high, and it needs the maintenance of the installer.
Performance characteristics:
A fuselage adopts heavy fuselage structure, which is welded by steel plate and throat stiffener. Integral tempering, stress relief, long-term use can ensure high rigidity and high precision.
B. The frame is enlarged and thickened, and the chassis is more stable. A solid foundation is extremely important in the processing of high-frequency emergency stop and emergency opening.
C. The turret with thick turret structure has better guiding performance. The tool rest adopts pairing processing technology to ensure the upper and lower coaxiality. The thickened turret lengthens the guide length of the die and improves the machining accuracy. The full insert structure is adopted, which prolongs the service life of the die and tool holder.
D the guide rail adopts the international brand HGH overload series linear guide rail, and the slider is lengthened to improve the bearing capacity and stability, as well as the instantaneous acceleration ability of the slider.
E. The world-leading four-wire support technology and guide rails on both sides solve the problem of jitter of long cantilever in high-speed emergency stop and emergency start movement.
F. This machine tool adopts ball screw and linear rolling guide rail, which has high grinding accuracy, extremely high X and Y axis motion accuracy, positioning accuracy and reliability.
G. The fixture adopts floating pneumatic fixture, which can float with the sheet metal in the process of machining to ensure the machining accuracy of the sheet metal. The front end of the fixture adopts thin structure, and the machining dead zone can be easily reduced by the upper and lower tool holders.
H lubrication system adopts centralized lubrication, which can conveniently send lubricating oil directly to each lubrication point, reduce the friction of each motion pair and improve the service life of the machine tool.
First, the bristle brush workbench has good supporting effect and low friction. It plays a very good role in protecting the surface of the processed plate from being scratched.
J. Equipped with the die sleeve independently developed by our company and the multi-station die sleeve with patent protection technology, the die can be changed quickly, and the upper and lower dies are coaxial without debugging, which greatly prolongs the service life of the die.
K. Industrial computer control, earthquake resistance, anti-interference, simple operation and friendly interface; Hard disk can store a large number of files;
Automatic conversion program of length AutoCAD graphics; There is a mold base library in the program, so it is not necessary to re-establish the mold base library, and the machining graphics can be previewed and modified in the CAD file.
After the meter program is executed, the plate can be automatically and repeatedly positioned, and the positioning is accurate, which can realize large-scale plate processing; In batch processing, one-key operation can be realized, which is convenient and fast;
