Problems solved by technology

[0003] Car sunroof guide rails generally need to be punched, trimmed, side cut, stretched, etc. in the production process. The existing stamping dies for car sunroof guide rails cannot be stamped and formed at one time. They must be divided into multiple processes and multiple pairs of stamping dies. Stamping and forming can only be completed, the investment in machine tools and equipment is large, the stamping time is long, and the cost is high, which is not conducive to the control of production efficiency and product quality

Abstract

The invention discloses a stamping die for punching, trimming, side cutting and stretching multi-profile surfaces in one step and a stamping method thereof. The die provided by the invention can be punch formed in one step, so that multiple stamping ways of punching, trimming, stretching and side cutting are completed. The invention breaks through a mode that a plurality of dies are required to carry out processing and production during stamping, thereby saving the cost and improving the production efficiency; and the existing multi-process processing mode is changed into a single-process processing mode, thereby reducing the turnover times and the process damage and helping to control the product quality.

Description

technical field [0001] The invention relates to the field of auto parts processing, in particular to a stamping die and a stamping method for multi-profile forming processing of a sunroof guide rail of an automobile. Background technique [0002] As cars enter the homes of ordinary people, users' requirements for car functions are becoming more and more perfect, and car sunroofs have gradually become the standard configuration of cars. The car sunroof guide rail is a key component of the car sunroof, its quality directly affects the performance of the car sunroof, and its manufacturing cost has an important impact on the cost of the car sunroof. The stamping process is the most important process for manufacturing automotive sunroof guide rails. The quality and efficiency of stamping determine the performance and cost of automotive sunroof guide rails. Therefore, it is very important for manufacturing enterprises to develop high-efficiency and high-quality automotive sunroof...
