Light alloy profile finishing machine

Abstract

The invention discloses a finishing machine for a light alloy section. The finishing machine for the light alloy section comprises a machine base, a finishing platform, a transmission device platform, a transmission device and a finishing wheel. The finishing platform and the transmission device platform are installed on the machine base. The transmission device platform is provided with guide rails. The transmission device is movably installed on the guide rails. The finishing wheel is installed on the transmission device. The finishing wheel is located above the finishing platform. According to the finishing machine for the light alloy section, the structure is simple, a section to be straightened is fixed to the finishing platform, the relative positions, in the vertical direction and in the direction from left to right, of the finishing wheel and the section are well adjusted, the transmission device is started, the transmission device drives the finishing wheel to move along the guide rails, the section is rolled and flattened through the finishing wheel, according to the deformation condition of the section, the rolling reduction of the finishing wheel and the position, in the direction from front to back, of the finishing wheel are adjusted gradually, the section generates deformation stress under the action of the finishing wheel so that defects can be eliminated, and finally, the product meets the dimensional requirement; compared with a traditional roller straightening mode, the rolling and flattening straightening mode has the advantage that scratches of the surface of a product are avoided.

Description

technical field [0001] The invention relates to the field of straightening machines, and more specifically relates to a finishing machine for light alloy profiles. Background technique [0002] As light metal structural materials, magnesium alloy and aluminum alloy are more and more widely used in the fields of automobile, rail transit, aerospace, national defense and military industry, etc., and the requirements for the precision of profiles are getting higher and higher, such as straightness and twist. Extrusion molding is one of the most important ways of processing light alloy profiles. In the process of extrusion molding, the uneven metal flow is often caused by factors such as the inhomogeneity of the internal structure of the billet, the difference in temperature distribution, and the design of the mold. Because of the effect of external force and uneven cooling rate after extrusion, the product is bent or twisted, and it must be corrected to obtain a qualified and fl...

Problems solved by technology

[0003] In the straightening method of metal profile deformed products, roller straightening is suitable for round pipes and bars, and multi-roller repeated bending and straightening is suitable for plates and some profile products. However, due to light alloys such as magnesium alloys and aluminum alloys The surface quality requirements of the product are relatively high. Roller straightening and multi-roller repeated bending straightening are not suitable for use because they are easy to scratch the surface of the profile.

Among the published patent documents about profile straightening equipment, most of them involve roller straightening and repeated bending straightening, such as: "Gantry Type Universal Metal Profile Straightening Machine" with patent No. 02244913.2, and patent No. 200620030560.2 "Magnesium Alloy Profile Straightening Machine" discloses roller straightening technology, but all may not be suitable for light alloy profiles such as magnesium alloy and aluminum alloy due to scratches on the product surface, and these straightening methods are only applicable Correction is based on the shape of the profile. For profiles with dark grooves, the bottom of the dark groove is easy to deform. At present, no suitable straightening equipment has been found.
