Anti-crease bending processor for thin metal pipe

Abstract

The invention discloses an anti-crease bending processor for a thin metal pipe, which comprises a base, wherein the base comprises a feeding component, a bending mold component, a guiding mold component, a clamping mold component, an anti-crease component and an electrical control system; and further, the bending component is provided with at least one bending mold which is subject to rotating transmission, the guiding mold component is provided with a guiding mold which is correspondingly matched with the bending mold, can get close to the bending mold component to guide a thin metal pipe and is used as the bending support point of the thin metal pipe, the clamping mold component is provided with a clamping mold which is correspondingly matched with the bending mold and rotates around the rotation axis of the bending mold component, and the anti-crease component is provided with an anti-crease block which is tangential to the bending mold. The invention realizes numerical control, has the advantages of high degree of automation and convenient and fast operation, and greatly eliminates the possibility of manual operation errors. Besides, the invention effectively solves the problems of the product on concentricity, ellipticity, burst, crease, angle rebound and the like, the ellipticity is limited within 8%, the concentricity and the angle rebound are limited within 0.1, so that operating requirements can be met. The invention can produce different thin-wall bent pipe products by replacing the molds and control programs, thereby lowering the manufacturing cost. At the same time, the invention can make multiple bends of different R angles in different positions within 2.5 meters in one loading and clamping process, thereby meeting user's technical requirements.

Description

technical field [0001] The invention relates to a bending processing device, which belongs to the technical field of deep processing machinery equipment, in particular to a wrinkle-resistant bending processing device for thin metal tubes. Background technique [0002] At present, the new products of some automobile customers need to be equipped with thin-walled pipeline series parts assembly, which is composed of multiple thin-walled elbow parts with different R angles and curved three-dimensional space. Because it can meet the requirements for light weight, toughness and low consumption of products, it can save production costs and energy consumption. [0003] In the prior art, the bending processing methods of thin metal tubes usually include: roll bending, die bending and dieless bending, which are generally completed by manual control by fixture and die positioning, resulting in low production efficiency and low yield , especially the mechanical properties such as stren...
