Efficient bent arc edge overturning device and application method thereof

Abstract

The invention is a high-efficiency arc-bending flanging device, which includes a positioning rod, a connecting block, a fixing block, a flanging bearing, and auxiliary wheels, and is characterized in that: the connecting block is arranged at one end of the positioning rod, and the fixing block It is arranged at one end of the positioning rod, a limiting groove is provided on the fixing block, and positioning plates are arranged on both sides of the limiting groove, the flanged bearing is arranged on the fixing block through a positioning bolt, and the auxiliary The wheel is arranged between the positioning plate and the positioning plate through the connecting shaft. In the present invention, a flanged bearing is arranged on the positioning bolt of the fixed block, and the flanged bearing is set as a structure that can adjust the position on the fixed block through the positioning bolt, so that the distance between the flanged bearing and the auxiliary wheel can be adjusted, which not only expands the The scope of application of the bending arc flanging device is widened, and it can also perform flanging at different depths of 0‑120° on the curved end of the outer metal skin of the bus. It also has the advantages of simple structure, convenient operation and high work efficiency.

Description

technical field [0001] The invention relates to a flanging device for mechanical processing, in particular to a high-efficiency arc-bending flanging device and a using method thereof. Background technique [0002] In the production of passenger cars, the outer skin parts that wrap the body frame need to be flanged. The flanging parts of the outer metal skin of most passenger cars are straight flanging. Most of the metal skins are arc-shaped ends, which need to be flanged. Due to the large variety of arc-shaped ends required for the outer metal skin of the bus, the output is small. Low profits, high manufacturing costs, and declining profits. The manual beating method will not only cause many hammer marks on the surface of the workpiece, but also make the surface treatment difficult in the later stage. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of high cost of mechanical flanging, low utilization rate, low efficiency...
