Abstract

The invention discloses a profile bending device. The profile bending device comprises a bottom plate, and a profile placing assembly, a positioning assembly, a bending assembly and a limiting assembly are arranged on the bottom plate. The profile placing assembly comprises a profile placing seat, an upper pad and a lower pad are arranged on the profile placing seat, and a flat shape profile placing cavity is formed between the upper pad and the lower pad; the positioning assembly comprises a positioning frame arranged on the bottom plate, and a first lower pressing member is arranged on the positioning frame; the bending assembly comprises a rotatable rotating frame, and a force member acting on a power member is arranged on the rotating frame; and a second lower pressing member is further arranged on the rotating frame. According to the profile bending device, fixing and supporting of profiles is firm, the deformation of the profiles is rare in the bending process, meanwhile, throughthe improvement of the upper pad or press block, the crack phenomenon of the profiles during the bending process is greatly reduced, and the bending quality of the profiles is high; and the bending device is accurate and stable in positioning, the bending precision is high, and the product quality is good.

Description

technical field [0001] The invention belongs to the technical field of profile processing, and in particular relates to a profile bending device. Background technique [0002] Metal profiles refer to solid or hollow straight bars with a certain cross-sectional shape and size after plastic processing. There are many varieties and specifications of profiles, and they have a wide range of uses, occupying a very important position in rolling production. At the same time, aluminum alloy is the most widely used non-ferrous metal structural material in the industry. It is widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. At present, aluminum alloy is the most widely used alloy material. [0003] Aluminum alloy profiles generally have a linear structure, and further processing, such as bending, is required when applied to a specific product structure. There are some profile bending equipment in the prior art. For example, i...
