Pipe bending machine and its chuck device

Abstract

The invention discloses a collet device, which includes a collet body, and also includes: a transmission device sleeved inside the collet body, one end of the transmission device is used for connecting with a collet extending into the collet body. The contact end to be contacted by the pipe bending; the signal processing mechanism for receiving the position signal of the other end of the transmission device and converting it into a control signal for controlling the opening or closing of the pipe bending machine. The chuck device provided by the present invention can effectively avoid the bending position deviation caused by the improper placement of the pipe to be bent relative to the chuck body, improve the bending accuracy of the pipe to be bent, and further reduce the probability of scrapping. Improve the production pass rate. The present invention also provides a pipe bending machine, including a collet device, and the collet device is any one of the above collet devices.

Description

technical field [0001] The invention relates to the technical field of pipe bender equipment, in particular to a pipe bender and a chuck device thereof. Background technique [0002] In air conditioners, many bent piping parts (such as bent copper pipes) are used. Some of the bent piping parts of the pipeline have strange shapes and need to be made into corresponding shapes according to the design requirements. In the past, bent piping The bending of the parts is done manually. With the advancement of technology, pipe benders specially used for bending pipe fittings have gradually appeared. [0003] Taking the CNC pipe bending machine as an example, the pipe to be bent is sent to the predetermined position through the feeding mechanism, and then the chuck device moves to the position of the pipe to be bent, clamps one end of the pipe to be bent, and then bends according to the program setting. Length and angle of rotation to bend the pipe to be bent. And when the collet d...

AI Technical Summary

Problems solved by technology

That is, once the pipe to be bent is shifted from the predetermined position in the axial direction, but the CNC pipe bender cannot recognize it, the bent pipe after bending does not meet the design requirements, and the probability of scrapping the bent pipe is high, while the production of the pipe bender is qualified. low rate
