Stamping device for shells of mini-tillers

Abstract

The application relates to the field of plate stamping, and particularly discloses a stamping device for shells of mini-tillers, which comprises a base, a female die, a male die, and a stamping machine, the female die is fixed to the base, the interior of the base is provided with a liquid cavity and diversion passages, a first piston plate is arranged in the liquid cavity, the first piston platedivides the liquid cavity into a first cavity and a second cavity, the interior of the female die is provided with a liquid inlet passage which is communicated with the die cavity, the liquid inlet passage is communicated with the first cavity, and the sidewall of the first cavity is provided with limit ribs; each limit rib is provided with a first quick connector which is connected to one end ofthe diversion passage, the other ends of the diversion passages are communicated with the second cavity, the first piston plate is provided with check valves and second quick connectors connected to the first quick connectors; the base is provided with a first oil cavity and a second oil cavity, a piston is arranged in the first oil cavity, a second piston plate is arranged in the second oil cavity, the upper end of the first oil cavity is communicated with the second oil cavity, and when moving upward, the male die can drive the second piston plate and the first piston plate to simultaneouslymove upwards; and water in the liquid cavity can get into the die cavity to flush the die cavity.

Description

technical field [0001] The invention relates to the technical field of plate punching, in particular to a punching device for a micro tillage machine shell. Background technique [0002] At present, when manufacturing a car, it is necessary to stamp the car shell to meet the installation requirements of the car. When stamping the car shell, a large stamping machine is usually used to stamp the car shell. However, due to the different stamping shapes, it is necessary to replace the die of the stamping machine and then stamp different shapes. Stamping processing is by means of conventional or The power of special stamping equipment makes the sheet material directly subjected to deformation force and deformed in the mold, so as to obtain the production technology of product parts with certain shape, size and performance. Sheet metal, mold and equipment are the three elements of stamping processing. Stamping is a metal cold deformation processing method. Therefore, it is call...

Problems solved by technology

[0003] When stamping the plate, some impurities or iron filings usually fall off the last processed plate in the cavity of the die. In this case, the plate is stamped, and the impurities or iron filings will make the formed shell The formation of pits will affect the aesthetics of the shell; therefore, when stamping the plate, the cavity of the die must be cleaned first, but at present, it is mainly cleaned manually, which is time-consuming and laborious
