Abstract

Disclosed is a plastic constraint component for bending a thin wall profile material. The plastic constraint component for bending the thin wall profile material comprises a plastic constraint component body, wherein the plastic constraint component body is made of plastic material and can achieve three dimensional bending, the plastic constraint component body is inserted into the profile material with an enclosed section or the profile material with a semi-enclosed section, or overall surrounds the profile material with an open type deformed section, and thereby restrains the surface of the profile material with the enclosed section, or the profile material with the semi-enclosed section or the profile material with the open type deformed section, and excellent surface quality of the thin wall profile material can be kept when the thin wall profile material severely deforms. The plastic constraint component for bending the thin wall profile material is simple in structure, easy to install and use, and wide in use range.

Description

technical field

[0001] The invention relates to a plastic constraining member, in particular to a plastic constraining member used for stretch bending or bending thin-walled profiles. Background technique

[0002] In the process of lightweight development of automobiles, metal parts made of thin-walled profiles, especially magnesium-aluminum alloy parts, are used more and more. Due to the complex assembly relationship with other parts, this kind of metal parts requires very high dimensional and shape accuracy. These characteristics determine that the manufacturing equipment of thin-walled metal parts must have high reliability and economy. Some metal parts made of thin-walled profiles are still A-level surface parts of automobiles, which have very high requirements for the surface quality of bending forming. At the same time, metal parts made of curved thin-walled profiles are also widely used in industries such as rail trains and high-speed railway passenger cars. [0003...
