Manhart How does the punch structure of a punching machine achieve punching operations?

The process of implementing punching operation through the punch structure of the punching machine can be mainly divided into the following steps. Here, we will combine the information in the reference article to clearly and systematically represent and summarize:
1. * * Punch composition and initial position * *:
-A punch usually consists of a hard alloy head and a steel punch seat.
-Before starting the homework, the punch is placed above the metal material to be processed, ready for punching operations.
2. * * Power transmission and punch movement * *:
-Under the drive of the hydraulic or mechanical system of the punching machine, the punch begins to move downwards. This process can be achieved by delivering hydraulic oil to the hydraulic motor through a hydraulic pump, creating a motor effect that drives the punch to move slowly downwards.
-When the punch comes into contact with the metal material, the hydraulic control valve is activated, causing the hydraulic pump to deliver a large amount of hydraulic oil to the hydraulic motor, thereby accelerating the downward movement of the punch.
3. * * Punching operation * *:
-When the punch impacts downwards at high speed, it generates a strong impact force on the metal material, causing it to deform and form the required holes.
-This process relies on the high-speed movement and strong impact force of the punch to ensure the quality and efficiency of punching.
4. * * Punch reset * *:
-After completing the punching operation, the punch slowly rises and returns to its initial position under the control of the hydraulic or mechanical system, preparing for the next punching operation.
5. * * Optimize structure and materials * *:
-In order to improve the performance and lifespan of the punching machine, the design of the punch structure and material selection have been carefully considered. For example, the punch structure of a handheld hydraulic punching machine may include pressure plates, springs, and other components, while the punch of a private punching machine may be composed of multiple protrusions, cylinders, cones, and other shapes. The material used is generally high-speed tool steel (HSS) or hard alloy (WC) to ensure its hardness and wear resistance.
In summary, the punch structure of a punching machine achieves fast and powerful up and down movement of the punch through the power transmission of hydraulic or mechanical systems, thereby completing the punching operation on metal materials. The design and material selection of the punch are aimed at improving the quality and efficiency of punching, ensuring the efficient and reliable operation of the punching machine in metal processing.
