Punches are equipment used to produce metal stamping parts, but many people do not know how a punch works. Precision metal stamping parts customization processing experience, can customize various complex precision stamping parts according to customer requirements. How does a punch press work? Next, I will tell you.

The punch press in the stamping parts processing plant uses the compressed air (or hydraulic oil) provided by the compressed air pump (or hydraulic pump) to enter the cylinder through the solenoid valve, and drives the piston to drive the main shaft to move downward, thereby forming an impact force and making the stamping parts The specified deformation is generated in the mold to achieve the purpose of processing. For the convenience of customers, the equipment has added an electronic control part, which greatly improves the work efficiency.

According to the different driving force, the punch can be divided into mechanical and hydraulic driving force, so the punch can be divided into mechanical and hydraulic punching force according to the different driving force.

The working principle of the punch: the upper part of the die is installed on the upper slider of the punch, and the lower die is fixed on the workbench of the punch through the pressing plate. After the power is turned on, the motor drives the flywheel. When the clutch is closed, the crankshaft rotates, and the connecting rod rotates with the crankshaft to drive the slider to reciprocate in a straight line up and down along the guide rail. When the brake is applied, the clutch disengages, the crankshaft stops rotating, and the slider stops moving up and down. The rotary motion is converted into the reciprocating motion of the slider, and the die completes the corresponding stamping process within one stroke of the punch.

The precision of the punch belongs to the overall precision, which is guaranteed by the cooperation of various precision parts. It is not advisable to guarantee the accuracy of only one part or a few parts.

The operation of the punching machine is completed by the cooperation of multiple systems outside the machine, and the operation of each system is related to the precision and speed of the stamping die. Therefore, in the process of use, in order to maintain the precision and production efficiency of the punch, the maintenance of the punch is also very important.
