Abstract

The invention discloses a fine adjustment device and method for a lifting type bent pipe, and belongs to the field of plastic processing of metal pipe fittings. The device comprises a base, a lifting assembly and a fine adjustment assembly, and the base is located below the device and used for supporting the whole device; the lower part of the lifting assembly is mounted on the base, and the top is provided with a fine adjustment assembly; the lifting assembly controls position adjustment of a lifting rack in the vertical direction through a lifting rack transmission gear set; the fine adjustment assembly controls a fine adjustment rack to move in a 45-degree inclination direction through a fine adjustment rack transmission gear set. According to the fine adjustment device for a lifting type bent pipe, secondary gradual change bending machining of a metal pipe is achieved, and the inclination angle of the fine adjustment rack is required to be 45 degrees. In this way, initial bending springback compensation of the metal pipe can be achieved, further minimum bending radius forming of the metal pipe can be achieved, and the bearing force effect on the lifting rack and the fine adjustment rack is good.

Description

technical field [0001] The invention belongs to the field of plastic processing of metal pipe fittings, and in particular relates to a fine adjustment device and method for a lifting type curved pipe. Background technique [0002] The free bending forming process of pipe fittings can realize the processing and forming of complex metal pipe fittings (such as spiral pipes, variable curvature pipes, etc.). Compared with traditional pipe bending forming equipment, the bending radius and bending angle of free-bending pipe fittings can be flexible at the same time, and the dependence on the mold is lower. From the perspective of structural features, the free bending forming die of pipe fittings is mainly composed of connecting accessories, movable dies, fixed dies and control mechanisms. [0003] Chinese patent CN111250576A provides a four-axis free pipe bending machine, which belongs to the field of plastic processing of metal pipe fittings; it includes a pipe feeding module, a ...
