Abstract
The invention discloses a manufacturing process of a drum type damping spring, which comprises the following specific processes of scraping an alloy steel plate or a steel belt, blanking, normalizing, rolling the alloy steel plate or the steel belt into a drum type through equipment rolling, sequentially quenching, tempering and shot blasting the pressed alloy steel plate or the pressed steel belt, finally carrying out full inspection and assembly, and cutting a positioning groove after the assembly is finished, thereby obtaining the final drum type damping spring. The process effectively solves the problems that the consistency of the roundness and the outer diameter of the formed dimension is poor, redundant materials need to be cut off and the dimension of the shape needs to be corrected subsequently, and then the alloy steel plate or the steel strip is pressed by rolling equipment, so that the dimension of the formed alloy steel plate or the steel strip is good at one time, the steps of correcting or cutting redundant materials subsequently are reduced, and the production efficiency and the performance of the assembled product are improved.
