Punching device for circular-tube-shaped steel member

Abstract

The invention discloses a punching device for a circular-tube-shaped steel member. The punching device comprises a circular-tube-shaped steel member and a punch which can be plugged into the circular-tube-shaped steel member tube, one end of the punch is provided with a punch-out boss for punching the pipe wall of the round-tube-shaped steel component, the cross section of the punching lug boss is oval, the other end of the punching head is provided with a matching part which is matched with the driving device to push the punching hole, and the punching device further comprises a clamp used for clamping the circular-tube-shaped steel component at the position corresponding to the punch. According to the punching device, the production steps of a traditional production process are reduced, the production efficiency is improved, the cost is reduced, according to the punching device, the punching is finished once, the quality stability of the product can be ensured, the product quality is improved, and the qualified rate of the product is improved.

Description

technical field [0001] The invention also relates to a punching device for round tubular steel components. Background technique [0002] At present, in the field of processing round tubular steel components, the processing technology of punching the tube wall of the round tubular steel component is involved. Generally, the punch is inserted into the tube of the round tubular steel component, and then the punch is driven by the driving device. The head moves along the radial direction of the round tubular steel member, so that the punch completes the punching and forms a certain height of flanging on the tube wall. But the traditional punch has the following deficiencies: the cross-section of the punched-out boss of the traditional punch punched through the pipe wall is circular, so that the end face of the flanging formed on the pipe wall after punching is uneven, and the punched hole The four sides of the pipe are uneven, and when the punching is completed, it will be tran...

AI Technical Summary

Problems solved by technology

But the traditional punch has the following deficiencies: the cross-section of the punched-out boss of the traditional punch punched through the pipe wall is circular, so that the end face of the flanging formed on the pipe wall after punching is uneven, and the punched hole The surrounding area of ​​the pipe is uneven, and when the punching is completed, it has to be transferred to other processes to repair the holes on the pipe wall, which seriously affects the production efficiency

Due to the follow-up repair process, the processing of the pipe wall hole of the circular tubular steel member is not formed at one time, so the quality of the product is uneven, resulting in a low pass rate of the product
