Description

Technical Field

[0001] This utility model relates to the field of pipe end-closing processing technology, and in particular to a quick-change tooling mechanism for pipe end-closing. Background Technology

[0002] The quick-change tooling mechanism for pipe end closing is a support device used for pipe end closing processing. It is used for the reduction and closing of metal pipe products and can process the ends of round pipes into different shapes, giving the round pipes better connectivity, sealing and aesthetics. With the continuous development of technology, people have higher and higher requirements for the manufacturing process of pipe end closing mechanisms.

[0003] Existing pipe closing mechanisms have certain drawbacks. First, they cannot be easily disassembled and replaced quickly, cannot adapt to more processing shapes, cannot meet the rapid switching of different products in automated production lines, and are relatively troublesome to close, resulting in poor processing efficiency. These factors have a certain adverse impact on actual use. Therefore, we propose a quick-change tooling mechanism for pipe closing. Utility Model Content

The end closing mechanism drives the end closing fixture inside the tooling to shrink inward, thereby reducing or closing the pipe end. Different clamps can be used to adapt to different cross-sectional shapes. The entire end closing tooling can be quickly changed through positioning pins and quick-release screws, thereby meeting the quick change between different products in the automated production line and effectively solving the problems in the background art.
