Pipe bender

Abstract

A pipe bender where the number of actuators can be reduced, operation is easily made even by hand, and even an unskilled user can produce a precisely bent pipe. A pipe bender where a pipe (P) is held by a clamp (15) and a bending die (12) with the pipe (P) received between the groove of the bending die (12) and the groove of a pressure (14) and in that state, the pressure (14) is rotated along the peripheral surface of the bending die (12) to bend the pipe (P). The bending die (12) is placed so as to be recedable from a bending point of the pipe (P). The bending die (12) is moved to the bending point in conjunction with bending operation by the pressure (14), and made to recede from the bending position in conjunction with return operation of the pressure (14).

Description

technical field [0001] The present invention relates to a pipe bending device, and more particularly to a pipe bending device suitable for manually bending a pipe. Background technique [0002] The basic configuration of the bending part of the pipe bending device is to include: a bending die that is arranged on a machine frame, has an arc-shaped peripheral surface, and has a groove formed on the peripheral surface, and is rotatable along the peripheral surface of the bending die. A pressure member provided on a machine frame having a groove at a position facing the groove of the bending die, and a state in which a tube is accommodated between the groove of the bending die and the groove of the pressure member provided on the frame This pipe is restrained by the jig of the above-mentioned bending die (for example, refer to Japanese Patent Application Laid-Open No. 10-211524 or Japanese Patent Laid-Open No. 2-284722). [0003] In addition, in such a pipe bending device, the ...

AI Technical Summary

Problems solved by technology

[0006] In the automatic pipe bending processing device, actuators are provided on the above-mentioned parts respectively, and the pipe can be bent three-dimensionally by controlling these actuators. However, when bending the pipe manually, all the above-mentioned operations must be performed manually. Not only is it troublesome, but it is also impossible to make high-precision tubes for unskilled workers.
