Problems solved by technology

[0007] In the automatic pipe bending processing device, actuators are provided on the above-mentioned parts respectively, and the pipe can be three-dimensionally bent 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.

Embodiment Construction

[0048] The present invention will be described below based on the embodiments shown in the drawings.

[0049] As shown in FIG. 1 , this pipe bending device includes: a bending unit 10 for bending a pipe, a bending angle setting unit 40 for determining the bending angle of the pipe, and a device for determining the feeding amount and bending direction of the pipe. The feed unit 60 and the like.

[0050] As shown in detail in FIG. 2 , the bending portion 10 is provided with a substrate 11 above the frame 1 with a gap therebetween. The base plate 11 is provided with a bending die 12 , a bending die operating piece 13 , a pressure member 14 , and a jig 15 , and a shaft 16 is rotatably supported between the frame 1 and the base plate 11 . Furthermore, one end portion of the operation plate 17 is integrally provided on the shaft 16 .

[0051] The bending die 12 has a partially arc-shaped peripheral surface 12a, and an arc-shaped groove 18 for accommodating the pipe P is formed on ...

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

[0001] The patent application of the present invention is a divisional application of the patent application for invention whose filing date is July 27, 2004, application number is 200480021893.2, and the title of the invention is "bending device for pipe". technical field [0002] 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 [0003] 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 o...
