双头螺柱的生产工艺一般是采用二次缩径、搓丝或滚丝工艺,生产效率高。但是它在分别缩径时,不同程度地存在着畸变,直接影响了产品的质量。为了解决产品的质量问题,我们除了对工件的材料、机床、工艺等采取措施外,同时还将二次缩径改为一次缩径,变无拘束正挤压,
Stud production process is generally used twice reduced, Roll or rolling process, high production efficiency. However, when it is respectively reduced in diameter, distortion exists in varying degrees, which directly affects the quality of the product. In order to solve the quality problem of the product, we not only take measures on the workpiece materials, machine tools and technology, but also reduce the secondary diameter to a reduced diameter at the same time,
