Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing, protection scope of the present invention is not limited to the following:

[0023] Such as figure 1 As shown, a thin-walled tube radial forming processing method is processed by using a thin-walled tube radial forming processing system, which is characterized in that: the thin-walled tube radial forming processing system includes a support table 1, several guides Column 2, several extrusion molding dies 3 and core molds 5. In this embodiment, the extrusion molding dies 3 are provided with a molding surface 31, and the core mold 5 is provided with a core mold surface. The compression mold 3 is annularly arranged around the support table 1. In this embodiment, the guide column 2 and the extrusion mold 3 are annularly arranged around the axis of the core mold 5, so as to ensure that each extrusion molding The distance from the molding surface 31 on the mold 3 to the axis of th...

Abstract

Disclosed is a thin-walled pipe radially forming processing method, which comprises feeding, clamping, processing and discharging, and uses a thin-walled pipe radially forming processing system to process. The thin-walled pipe radially forming processing system comprises a supporting platform (1), a plurality of guide columns (2), a plurality of extrusion forming moulds (3) and a core mould (5) used for clamping a blank (4), wherein the guide columns (2) and the extrusion forming moulds (3) are annularly arranged around the supporting platform (1), the guide columns (2) and the extrusion forming moulds (3) are in a wedge-shaped connection, the core mould (5) is arranged above the supporting platform (1), the supporting platform (1) is used for supporting the blank (4), a mould forming face (31) is arranged on the extrusion forming moulds (3), and a core mould face is arranged on the core mould (5). The method can be used for the forming process of a thin-walled tubular part and has the advantages of being simple in operation, convenient in use, high forming accuracy and high working efficiency etc.

Description

technical field [0001] The invention relates to a thin-walled pipe processing method, in particular to a thin-walled pipe radial forming processing method. Background technique [0002] Thin-walled parts have been increasingly widely used in various industrial sectors because of their light weight, material saving, and compact structure. However, the processing of thin-walled parts is a difficult problem in the field of mechanical processing. The reason is that thin-walled parts have poor rigidity and weak strength. Thin-walled plate-like parts are prone to warping and pits during processing, which makes the flatness and parallelism of the parts less than the required precision. Thin-walled tube-mounted parts have problems such as difficult clamping, prone to distortion and deformation, and easy to cause the parts to be flattened, so that the accuracy of the roundness, cylindricity, and parallelism of the parts cannot meet the requirements.
