Problems solved by technology

This technology can quickly and conveniently replace the pipe bender and mold components through the engaging device, but the disadvantages are: 1. In-plane and out-of-plane bending of special-shaped pipes such as flat pipes, rectangular pipes, and harmonica pipes cannot be realized
Second, the bending method of rolling forming is adopted, and the forming quality needs to be improved
Third, for different bending radius requirements, different heights and different widths of pipe bending, it is necessary to replace the entire set of molds, and the cost is relatively expensive

Abstract

A device for shaping a special-shaped tube through bending belongs to the technical field of machining, and comprises a bend part, a central shaft, a holding part, a booster part, a rotation handle and a platen, wherein the bend part and the booster part are respectively fixed on the platen, the central shaft passes through the bend part, and the holding part is fixedly connected with the bend part which is fixedly connected with the rotation handle. The device uses a mode of twisting to realize bending, and has the advantages of high efficiency and good shaping effect. The bend part is divided into three layers, and an adjusting sheet of 0.1mm can be added on the medium layer for bending cores to realize fine adjustment and to set a fine gap for good bending quality, thereby effectively controlling bend, crumple and distortion of cross-section.

Description

technical field [0001] The invention relates to a device in the technical field of mechanical processing, in particular to a special-shaped tube bending forming processing device. Background technique [0002] Pipe bending is an important means of forming pipe parts. Bending pipe fittings are widely used in automobile oil circuit, heat exchanger, air conditioner, refrigerator, aerospace industry and other equipment. From the perspective of theoretical research, the bending deformation of metal pipes includes the high nonlinearity of material, geometry and contact in the plastic forming of sheet metal. They are also very prominent in forming. Due to the particularity of the geometric shape, the plastic forming of the pipe will also produce cross-sectional distortion that makes the deformation more complicated, which will bring trouble to the relevant theoretical research. Therefore, a bending device is needed to assist the research. However, due to the special structure of ...
