Abstract

The invention discloses a staggered-distance extrusion forming device and method for a bending component, and relates to a extrusion forming device and method for the bending component. The device andthe method aim to solve a series of problems that in a traditional bending component manufacturing process, the number of required procedures is large, the flexibility of the component is poor, the production efficiency is low, and quality control is difficult to achieve. According to the method, a conventional integral punch for extruding is divided into two or more than two split structures; the split punches are arranged in a staggered manner according to a certain relative displacement amount and fixed; then integral loading forming of blanks is carried out; and the curvature change of the bending component subjected to extrusion forming can be regulated. The single shape feature that conventional extrusion products are mostly long straight lines is broken through, the variety range of the products capable of being formed is enriched, and the application field also tends to be diversified. According to the method, the double effects that extruding and bend and forming are integrated are achieved in a single-pass extrusion technology process, additional procedures are not needed, the required bending component can be machined at one time, the machining process is shortened, theproduction efficiency is improved, and the manufacturing cost is reduced. The staggered-distance extrusion forming device and method for the bending component is used for extrusion and machining forming of the bending component.

Description

technical field [0001] The invention relates to a metal extrusion forming method, in particular to a bending member offset extrusion forming method, and belongs to the technical field of bending member extrusion forming. Background technique [0002] Bending is a plastic processing method that bends blanks or semi-finished products such as plates, pipes, profiles, etc., into components with a certain angle or a certain shape with molds or other tools. It can achieve lightweight manufacturing effect and can meet various practical needs of structural parts with curvature in different shapes. Therefore, it is widely favored by aerospace, automobile, shipbuilding and other fields, and it is a green manufacturing technology. [0003] At present, there are many processes for component bending, mainly including: press bending, roll bending, push bending, numerical control bending, local heating bending and laser bending, etc., but the process principles and characteristics of vario...
