Punch is a multi-functional stamping press, which can be used in the field of metal processing to make blanking, punching, forming, drawing, dressing, fine blanking, shaping, riveting and extrusion parts by matching molds.
1. Category:The punch press is divided according to the driving force of the slider, which is divided into mechanical punch, pneumatic punch, servo punch and hydraulic punch.
1. Mechanical punch:The carriage movement is driven by mechanical transmission parts.
2. Pneumatic punch:Compressed air is used as a power source to drive the slider to move.
3. Servo punch:The power generated by the servo motor is used to drive the slider.
4. Hydraulic punch:Power is generated through the hydraulic system to drive the carriage to move.
Second, the working principle:Punch presses work by converting circular motion into linear motion. The main motor outputs the force to drive the flywheel, and drives the gear, crankshaft (or eccentric gear), connecting rod, etc. through the clutch to realize the linear motion of the slider, and the plate is stamped and formed with the mold.
3. Uses:Punch presses are widely used in electronics, communications, computers, household appliances, furniture, transportation (such as automobiles, motorcycles, bicycles) and other industries, mainly used for stamping and forming of metal parts.
Fourth, the operation method:
1. Boot check:The whole machine is inspected on the punch to ensure that the functional components and transmission devices of the punch press work normally.
2. Install the mold and feed the materialThe die is installed on the punch table and fixed with a clamp, and then the sheet metal is introduced into the mold.
3. Adjust the parameters of the punch pressAdjust the stroke and frequency of the punch according to the material and product requirements to be processed.
4. Mold test:Perform a trial stamping to ensure that the die is set correctly.
5. Continuous stamping:Start of the formal continuous production process.
5. Purchase Guide:
1. Selection of punch tonnage and stroke:It is determined according to the width, thickness and die requirements of the stamping material.
2. Speed selection:The speed of the punch is determined according to the production volume and speed requirements.
3. Style selection:According to the accuracy requirements of the product, select the appropriate punch style.
Sixth, maintenance:
1. Regularly inspect and maintain all parts of the punch to ensure its normal operation.
2. Keep the punch and its working environment clean, and check whether the transmission, connection, lubrication and other parts of the punch and the protective safety device are normal.
3. Carry out regular professional maintenance and inspection according to the guidelines of the punch press manual.
