Fixing assembly for perforating device for sealing elements

Abstract

The invention discloses a fixing assembly for a perforating device for sealing elements. The fixing assembly comprises an operating table, a fixing assembly body is arranged on the top of the operating table and comprises two baffles and two connecting blocks, the two baffles are fixed to the top of the operating table, a storing tank is formed between the two baffles and is located right below six drilling assemblies, clamping grooves are formed in the two sides of the bottom of each connecting block, the two connecting blocks are connected to the two baffles through the clamping grooves, storing cavities are formed inside the two connecting blocks, pull rods penetrate through the storing cavities, the ends, located in the connecting blocks, of the pull rods are connected to lifting columns, the other ends of the pull rods extend into the storing tank and are connected to pressing blocks, the bottoms of the pressing blocks make contact with the top of the operating table, and springs and locating blocks are connected to the surfaces of the parts, located inside the storing cavities, of the pull rods in a sleeving mode. The fixing assembly is simple in structure, convenient and fast to operate and convenient to popularize, can fix sealing strips through cooperation among the springs, the pull rods and the pressing blocks, is good in fixing effect and has the adjustment function.

Description

technical field [0001] The invention relates to the technical field of sealing element processing, in particular to a fixing part of a sealing element punching device. Background technique [0002] Seals are materials or parts that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the internal parts of the machine. The seal includes a kind of automobile sealing strip. The automobile sealing strip is one of the important parts of the automobile. It has strong tensile strength, good elasticity, good temperature resistance and aging resistance, and the automobile sealing strip is formed after forming Punching is required. However, the drill bit of the traditional punching machine will generate heat after working for a long time, so that the temperature of the punching part of the sealing strip is very high. Cold drilling device, such as patent CN 203409828 U, discloses an air-cool...

AI Technical Summary

Problems solved by technology

However, the drill bit of the traditional punching machine will generate heat after working for a long time, so that the temperature of the punching part of the sealing strip is very high. Cold drilling device, such as patent CN 203409828 U, discloses an air-cooled online drilling device for sealing strips. By setting an air-cooling device on the drill bit, the desired effect is achieved, but there is no sealing strip that can be firmly fixed on this device. When punching holes, the sealing strip is prone to shift, which makes the sealing strip perforated unevenly, and thus becomes a waste product, which will cause economic losses and waste of manpower.
