Description

Technical Field

[0001] The utility model relates to the technical field of stair guardrail processing, in particular to an arc punching device for stair guardrail processing. Background Art

[0002] The stair guardrail is made of round tubes with oblique arcs butt-welded. When welding different metal pipes, the uneven ends of the metal tubes cause the end faces of different metal tubes to not correspond to each other. Generally, it is necessary to punch the end faces of the metal round tubes into corresponding arcs before welding to increase the effective contact area of ​​welding.

[0003] A punching device for a round tube punching machine disclosed in the Chinese utility model patent application disclosure CN210701949U is a device in which a worker holds one end of the round tube and manually inserts the round tube into a second through hole, and uses the driving mechanism to drive the cutter body to slide back and forth in the first through hole, so as to drive the cutter head to punch the two sides of the same end of the round tube in succession. The whole device is convenient for manual operation and has a simple structure. After completing one punching, the rotating round tube is fixedly positioned by the limiting device before the second punching, so as to ensure that the round tube is small in size after the second punching, and can be carried easily, and can be used in steel pipe construction sites. However, the current railing punching device requires manual holding of the railing to keep it stable, which is time-consuming and labor-intensive, and is prone to displacement during processing, affecting the processing quality.
