Description

Technical Field

[0001] The invention relates to the technical field of tube expansion dies, in particular to a slider type tube expansion die. Background Art

[0002] Pipe expansion is the process of processing thin pipes into thicker pipes using different techniques. It is a cold plastic forming process. It usually uses a conical mold to pass through the inner hole of a metal pipe under pressure, so that the inner diameter and outer diameter of the metal pipe expand. The expansion deformation of metal pipes can improve the cross-sectional shape of the pipe and improve the dimensional accuracy of the pipe.

[0003] There are certain shortcomings in the prior art when expanding the pipe opening of pipe fittings. First, when the existing pipes are placed on the device and fixed, they are mostly fixed manually and mechanically. The operation process is cumbersome and requires multiple operators to use multiple devices, which is very cumbersome. Second, since each operation process requires manual intervention, the efficiency is not high. In particular, after the pipe processing is completed, it needs to be taken out manually. The pipe is stuck in the mold due to the pressure during processing, and it is time-consuming and laborious to take it out, and there are great safety hazards. Third, if large-scale processing is required, if the lengths of each batch of pipe fittings are different, the device adjustment is troublesome, so it cannot meet the actual requirements.
