L-shaped plate arc-extruding forming device and method

Abstract

The invention discloses an L-shaped plate arc-extruding forming device and method, and belongs to the technical filed of machining and production of sheet metal structure parts. The L-shaped plate arc-extruding forming device comprises a working platform, the working platform is sequentially provided with a jacking clamp, a straight-moving sliding block and a bending device from front to rear; thebending device comprises a rotating motor which is connected with a rotating shaft, the rotating shaft is connected with a flanging rotating barrel, and the bottom of the flanging rotating barrel isprovided with a protruding rail I; the front side of the flanging rotating barrel is provided with a strip-shaped opposite-extruding film which is provided with a U-shaped rail; the left side of the bottom of the flanging rotating barrel is provided with a leading clamp; the right side of the bottom of the flanging rotating barrel is provided with an wrinkle-proof guide die which is provided witha protruding rail II; the protruding rail I and the protruding rail II are connected in an end-to-end mode; and a bending cavity is formed among the U-shaped rail, the protruding rail I and the protruding rail II. According to the L-shaped plate arc-extruding forming device and method, one-time quick machining arc forming can be conducted on an L-shaped plate, the efficiency is high, and due to the fact that a splicing technology is not needed, the product quality can be guaranteed better.

Description

technical field [0001] The invention relates to the technical field of processing and production of sheet metal structural parts, in particular to an arc extrusion forming device and method for an L-shaped sheet. Background technique [0002] With the continuous improvement of the quality of human life, the requirements for aesthetics and comfort are gradually increasing. Such as furniture manufacturing industry, interior and exterior decoration industry, construction engineering industry, automobile manufacturing industry, bus manufacturing industry, car manufacturing industry, machinery parts processing industry, beauty decoration industry, photovoltaic new energy industry, electrical control industry and other industries, In the pursuit of product appearance aesthetics or use functions, there are inevitably demands for arc surfaces and special-shaped surfaces. [0003] In order to meet the above needs of people, the current common bending process is basically the princip...

Problems solved by technology

[0003] In order to meet the above needs of people, the current common bending process is basically the principle of pressing down, that is, applying pressure to the part of the workpiece that needs to be bent to make it deform, but this process is obviously not suitable for bending all workpieces into arcs, such as The traditional process of bending L-shaped plates into arcs is mainly segmental processing, splicing, welding, and grinding, and requires the operator to have quite superb skills. The traditional process of bending L-shaped plates into arcs is not only cumbersome to operate , the efficiency is low, and the splicing effect cannot be guaranteed, which seriously affects the product quality and greatly limits the development of the industry
