Take you to understand the working principle of the punch

by:Fortuna     2021-03-06
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 the main shaft to make the main shaft move downwards, thereby forming an impulse. Make the stamping parts produce a prescribed deformation in the mold to achieve the purpose of processing. In order to facilitate the use of customers, an electrical control part is added to the equipment, which greatly improves the work efficiency. Punching presses can be divided into mechanical and hydraulic drive forces according to different drive forces. Therefore, presses can be divided into mechanical presses and hydraulic presses according to the different drive forces used. The working principle of the punch: the upper part of the mold is installed on the upper slide of the punch, and the lower mold is fixed on the worktable of the punch with a pressure plate. After the power is turned on, the motor drives the flywheel. When the clutch is closed, the crankshaft rotates, and the connecting rod follows the crankshaft. The rotation of the slider drives the slider to move up and down linearly along the guide rail. When the brake is applied, the clutch is removed, the crankshaft stops rotating, and the slider stops moving up and down. The rotary motion is transformed into the reciprocating motion of the slider, and the die completes the corresponding stamping process in one stroke of the punching machine. The accuracy of the punching machine belongs to an overall accuracy, which is guaranteed by the coordination of all precision parts. Any guarantee of the accuracy of only one part and several parts is not desirable. The operation of the punching machine is completed by the cooperation of multiple systems within the machine. The operation of each system is related to the accuracy and speed of the stamping die. Therefore, in order to maintain the accuracy and production efficiency of the punching machine during use, the maintenance of the punching machine It is also crucial.
