Pipe bending device with radial loading rotation and centering positioning and pipe bending method

Abstract

The invention discloses a pipe bending device with radial loading rotation and centering positioning and a pipe bending method. The pipe bending device comprises a bending machine and a radial rotarydevice, wherein the bending machine comprises a rack, bending devices and centering devices, two centering devices are respectively arranged on baffles on both sides of the rack, a feed mechanism is arranged above the centering devices, more than one bending device is arranged on the rack located between the two baffles and is located at a mounting groove, and the radial rotary device is arrangedon a platform located at the mounting groove. According to the structure, a workpiece is clamped in a radial loading mode, and the rotation of the workpiece is realized, so that the workpiece can be bent in different plane directions, the workpiece is precisely centered and positioned by the centering devices, and the processing original point is conveniently determined; all devices and baffles which are located at the mounting groove can move along the mounting groove, so that bending can be performed in different positions, and the bending in the different positions and on different bendingplanes can be realized.

Description

technical field [0001] The invention relates to the technical field of pipe bending devices, in particular to a pipe bending device and a pipe bending method that are radially loaded, rotated, and centered. Background technique [0002] For electric heating tubes, complex multi-plane and angle bending moldings are required. Usually, only traditional simple molds can be used for processing, and the tube material can be bent and corrected multiple times by manual methods. [0003] Using simple mold bending, the processing accuracy is difficult to be guaranteed. Some also need to design and manufacture special molds to complete the processing. For the situation where there are different bending planes and multiple bending points, it is necessary to manually adjust the bending plane and the bending datum in the pipe bending. Since accurate standardization cannot be achieved, the workpiece processing datum and the springback after processing cannot be achieved. Guaranteed, the ...

Problems solved by technology

[0005] However, if this invention needs to bend the bent pipe in different planes, it needs to be completed by multiple sets of equipment. In this way, the bent pipes in different processes need to be displaced and repositioned. The efficiency and accuracy will be relatively reduced
