Technical Field

[0001] The utility model relates to the technical field of clutch diaphragm springs, in particular to a punching machine for processing clutch diaphragm springs which is convenient for trimming burrs. Background Art

[0002] The clutch diaphragm spring is a special spring that plays an important role in the clutch. The design of the diaphragm spring allows it to deform when it is subjected to pressure and return to its original shape after the pressure disappears. This spring is usually made of a thin elastic steel plate with a certain taper and multiple radial grooves in the center to provide the required nonlinear elastic characteristics.

[0003] According to application number 202320666345.5, a horizontal spring stamping machine includes a shell, a stamping mechanism installed inside the shell, and a driving mechanism for driving the stamping mechanism. The stamping mechanism includes a lower die fixedly installed on a fixed seat inside the shell and slidably installed on the fixed seat. The lower die is used to place parts to be stamped. The driving mechanism includes an upper die and a driver for controlling the movement of the upper die.

[0004] The horizontal stamping equipment set by the device is provided with a discharge port at the bottom of the shell below the lower die, and a baffle with adjustable position is installed at the bottom of the lower die.
