A kind of plate shearing machine and the production process of explosion-proof wave valve using the plate shearing machine

Abstract

The present application relates to a shearing machine and the production process of the explosion-proof wave valve using the shearing machine. Knife and the first driving member that drives the upper cutting knife to slide vertically, a space for plate cutting is formed between the lower cutting knife and the upper cutting knife, and a pressing device is arranged on the upper cutting knife. The pressing device includes a protective net frame arranged on the upper cutting knife, a pressing plate connected to the protective net frame by sliding in the vertical direction, and a pressing spring for maintaining the pressing state of the pressing plate and the sheet material. The protective screen frame is located on the side of the lower cutting knife towards the feeding end, and the surface of the pressing plate close to the lower cutting knife is used to press against the plate. This application has the effect of cutting precision of the sheet.

Description

technical field [0001] The present application relates to the field of explosion-proof wave valve production, in particular to a shearing machine and an explosion-proof wave valve production process using the shearing machine. Background technique [0002] When producing explosion-proof wave valves, it is necessary to use steel plates, which need to be cut with a shearing machine, and cut to the required length before they can be used. [0003] The Chinese utility model patent with the authorized notification number CN209077887U discloses a shearing machine for spring steel, including a casing, a push motor and a material control screen. A material control screen is fixedly installed on the left outer wall of the casing. A driving motor is movably installed, a hydraulic pump is fixedly installed on the top of the casing, and two air cylinders are fixedly connected on the top of the casing. It has the effect of improving the quality of material production. [0004] The end ...

AI Technical Summary

Problems solved by technology

[0005] In view of the related technologies mentioned above, the inventor believes that there are the following defects: when cutting, some scrub pads are in conflict with the plate, and the spring presses the scrub pads against the plate; There is still vibration of the plate, which leads to the reduction of the shearing accuracy of the plate not between the two frosted pads, and the sealing degree of the explosion-proof wave valve will be reduced when the explosion-proof wave valve is installed.
