Full-moving type multi-chuck cutting device and method

Abstract

The invention provides a full-moving type multi-chuck cutting device and method. The full-moving type multi-chuck cutting device comprises at least three chucks capable of moving left and right and synchronously rotating, and when a pipe is cut, the pipe is clamped in the three chucks, so that the rotation of the pipe is reduced; and during normal cutting, the chucks drive the pipe to move forwards and backwards and rotate, a cutting head is used for cutting, and the cutting head is lifted when the last section is cut; and the first chuck loosens a claw and moves forwards to exceed a certain distance of the cutting head, the position of the first chuck before the middle chuck moves forwards is replaced, the last chuck and the middle chuck jointly clamp the pipe to move forwards and backwards and synchronously rotate, and after the head end part of the last material is cut completely, the second chuck moves forwards by a certain distance over a laser head, the third chuck feeds the pipeforwards and moves to the position of the second chuck before moving to the position of the previous second chuck, the first chuck grasps the pipe, and the cutting head is used for cutting the last section of the pipe. The last section of pipe can be fully utilized, the tail material is reduced, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of cutting devices, in particular to a fully mobile multi-chuck cutting device and method. Background technique [0002] With the development of the modern machinery industry, the requirements for pipe cutting quality and precision are constantly improving, and the requirements for improving production efficiency, reducing production costs, and automatic cutting functions are also increasing. The automatic pipe cutting machine is currently the latest type of pipe cutting machine in China's metal pipe cutting equipment market. It does not require a lot of traditional manual operations at all, and has higher mechatronics. Even one person can operate multiple sets, reducing employees and improving factory production efficiency. [0003] Existing automatic pipe cutting machines usually include two chucks. The front chuck is fixed near the laser head, and the rear chuck clamps the pipe to move back and forth. The...

AI Technical Summary

Problems solved by technology

This double-chuck cutting device is prone to sagging and swinging of the pipe during cutting, which greatly affects the cutting accuracy, and there is a distance of at least 200MM between the two chucks, which makes the pipe between the two chucks Can not be used, resulting in waste of pipes
