Numerical control technology has been widely used in the automotive sheet metal machine. It solves the problems of high precision, complex shape and large batch in sheet metal processing. Including CNC cutting machine, CNC welding machine, laser cutting machine, CNC punching machine. Their application in production greatly improves the sheet metal processing capacity, ensures the quality and output value of sheet metal parts, and greatly reduces the labor intensity of workers.
S stamping is an important part of sheet metal processing, CNC punch can replace the past three punch processing capacity. Productivity has been greatly improved. CNC punch is a widely used machine tool, there are single punch and turret. Taking Amada pega35784 as an example, the machine tool is made in Japan. Processing range: 1830 × 1520 mm, the turret has 58 die stations, which are divided into upper and lower parts. The punch and female die of the die are respectively responsible for stamping. The CNC punch generally has x, y and Z axes. The x-axis is the 0 degree direction of the machine tool, the y-axis is the 90 degree direction of the machine tool, and the z-axis is installed on the turret to control the view point of the die.
According to the part drawing and process requirements, the machine operator determines the processing scheme and compiles the program sheet. With the development of CAD / CAM and CIMS technology, the operator can input the graphics into the computer to generate the program, copy them into the disk, and input them into the CNC system through the disk drive to perform the processing.
The accuracy of sheet metal cutting process is directly affected by the application of numerical control shearing machine. CNC plate shears are composed of CNC equipment, servo system, measuring equipment and machine tools. The servo system is composed of three servo motors and servo driving equipment. There are two servo motors in front of the machine. Usually, one main motor works independently, and the processing range is 2-500mm. If the bevel is processed, the auxiliary motor works. The numerical control system gives two different instructions to form the bevel. Most of the products are servo motor.
