Cold Extrusion Forming Process Of 6061 Aluminum Alloy Spline Shell
Cold extrusion is a technology that is developed on the basis of traditional plastic processing. It saves materials, saves energy, shortens the product manufacturing cycle, reduces production costs, and obtains reasonable metal streamline distribution. The cold forging process also improves the forgings’ carrying capacity, safety, reliability, and service life.
For forging parts with special shapes, difficult to machine and more suitable for cold extrusion, this process has incomparable advantages. Because of the advantages mentioned above, coupled with industrial development needs, the new technology has developed rapidly in the last 20 years.
6061 aluminum alloy spline housing is a common cold extruded part. For a long time, the parts were produced by machining methods, which took a lot of time, had a poor material utilization rate of less than 20%, and the mechanical properties of the forgings did not meet the requirements for use. In order to save materials, reduce processing time, and improve product quality, cold extrusion comes in handy.
According to the results of numerical simulation analysis, surface treatment and lubrication experiments of 6061 blanks, after further improving the precision cold extrusion process of 6061 aluminum alloy spline shell, the spline problem in the cold extrusion of this part was successfully solved.
The pull cracks, napped defects, and the final product meet the requirements of the parts. The 6061 aluminum alloy spline housing is produced through the precision cold extrusion process. Compared with the traditional process, it can help users obtain greater economic benefits and greatly improve production and processing efficiency.
The specific advantages of cold extrusion forming process of 6061 aluminum alloy spline shell include:
(1) A small machining allowance, which can effectively save materials. The material utilization rate can be increased to more than 60%, and the performance of parts is also improved.
(2) The dimensional accuracy of the parts is high, and the surface quality is good.
(3) The inner and outer splines are formed by cold extrusion at one time without subsequent machining, and this increases the production efficiency.
CXIN Forging focuses on product development and cold forging manufacturing of metal parts and components. Compared with other technologies such as turning, engraving or hot forging, our cold forgings have a better surface finish, near-net shape, and almost no need for finishing. This saves manufacturing costs, and thus our products are cheaper.
The cold forging processing technology is particularly suitable for the long-term production of lightweight parts. If you are interested in 6061 aluminum alloy cold forging forming, feel free to contact us.
