A processing device, processing technology and product for cold forming of metal profiled long material

Abstract

The invention discloses a machining device for metal special-shaped long material cold forming. The machining device comprises an unwinding unit, at least two cold forming units and a winding unit which are sequentially arranged in the machining direction; each cold forming unit comprises a first straightening assembly, a cold rolling assembly and a roller die assembly; and a metal special-shapedlong material can sequentially pass through each first straightening assembly, each cold rolling assembly and each roller die assembly. According to the machining device for metal special-shaped longmaterial cold forming, due to the arrangement of the corresponding first straightening assembly, the corresponding cold rolling assembly and the corresponding roller die assembly in each cold formingunit, the cold forming calendering precision and the straightness of the machined metal special-shaped long material can be guaranteed to the maximum extent; and meanwhile, due to the arrangement of the at least two cold forming units, continuous roller pressing of the metal special-shaped long material can be achieved, and cold forming machining of the large size and large specification metal special-shaped long material is achieved.

Description

technical field [0001] The invention relates to the field of cold forming processing of metal irregular long materials, in particular to a processing device, processing technology and products for cold forming of metal abnormal long materials. Background technique [0002] Metal profiles are special-shaped metal wires that can be used in many industries such as petrochemical, mining, papermaking, screening filters, automobiles, aerospace, aviation, and medical equipment. The demand for them is huge. With the development of large-scale machinery industry, the size requirements for metal profiles are getting higher and higher. Since the metal profile with a large radial dimension can be applied to larger machinery, and the metal profile with a large axial dimension is more convenient for subsequent processing and transportation. Therefore, based on the above facts, the demand for large-scale metal profiled long products with large radial and axial dimensions continues to incr...

AI Technical Summary

Problems solved by technology

However, due to its structural limitations, the traditional calendering equipment used for cold forming of metal wires can only be applied to the processing of special-shaped wires with small radial dimensions (below 8mm), small axial dimensions and low area reduction requirements. , while the radial and axial dimensions are large and the special-shaped long products require high area reduction rate, such as special-shaped long materials with a diameter between 10mm and 25mm and an area reduction rate between 30% and 50%. Advanced calendering equipment cannot be directly processed and produced, and multiple calendering equipment cooperates with processing. On the one hand, the production efficiency is low. On the other hand, the calendering accuracy and straightness of the processed metal profiled long products cannot be guaranteed.
