Abstract

The invention discloses a chuck device. The chuck device comprises a chuck main body, and further comprises a transmission device sleeved in the chuck main body, wherein one end of the transmission device is a contact end contacted with a pipe to be bent extending in the chuck main body; and a signal processing mechanism is used for receiving a position signal of the other end of the transmission device and converting the position signal to a control signal for controlling the starting or shutting down of a pipe bending machine. The chuck device, provided by the invention, effectively prevents the condition of bent position deviation caused by placement of the pipe to be bent not in place corresponding to the chuck main body, so that the bent preciseness of the pipe to be bent is improved, the waste probability is reduced, and the production pass percent is increased. The invention further provides a pipe bending machine; the pipe bending machine comprises a chuck device; and the chuck device is any one of the chuck 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...
