Automatic shaft pulling and threading machine

Abstract

The invention discloses a fully automatic shaft pulling and pipe threading machine, which relates to the technical field of automatic assembly equipment. The tube-piercing platform has a first end and a second end, and the tube-piercing platform is used to place the tube body; the rolling and pulling shaft assembly is set on the tube-piercing platform, and the expanding mandrel is conveyed from the first end to the second end, so that the expansion The tightening mandrel penetrates into the tube body on the tube-piercing platform; the pre-pulling assembly for the pulling-shaft is arranged on the tube-piercing platform, and includes a clamping piece, and the clamping piece can move toward or away from the first end, and is used to move the tightening mandrel from the The pipe body of the previous process is pulled out and transported to the first end; the exhaust head of the exhaust assembly is used to exhaust the expansion mandrel located in the pipe body of the previous process; the inflatable head of the inflatable assembly is used to The inflation mandrel inside the tube is inflated. The technical scheme of the present invention provides a fully automatic shaft pulling and pipe threading machine that can reduce labor intensity and improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of automatic assembly equipment, in particular to a fully automatic shaft pulling and pipe threading machine. Background technique [0002] During the packaging process of rolled products, an expansion mandrel needs to be inserted into the tube body, and then the tube body is rotated under the rotation of the expansion mandrel, and then the material is wound on the tube body, and finally the expansion mandrel is It can be pulled out from the tube body to form a rolled product. [0003] In the prior art, the expansion and tightening mandrel needs to be manually exhausted, and after the exhaust is completed, the expansion and tightening mandrel is manually pulled out from the tube body, and before the next use, it is also necessary to manually expand and tighten the exhaust. The mandrel is inserted into the tube body, and then the expansion mandrel is inflated to limit the expansion mandrel in the tube body. ...

Problems solved by technology

[0003] In the prior art, it is necessary to manually exhaust the expansion mandrel, and after the exhaust is completed, manually pull out the expansion mandrel from the tube body, and before the next use, it is also necessary to manually de-tighten the exhausted mandrel. The mandrel penetrates into the pipe body, and then inflates the expansion mandrel to limit the expansion mandrel in the pipe body. Therefore, it is necessary to manually complete the process of pulling out the shaft and threading the pipe, resulting in high labor intensity and low work efficiency.
