Hot stamping forming process for preparing vehicle driving belt wheel actuating cylinder

Abstract

The invention discloses a hot stamping forming process for preparing a vehicle driving belt wheel actuating cylinder. The hot stamping forming process comprises the steps of blanking, specifically, aplate is put into a blanking die for blanking, and a blank obtained after blanking is cleaned to remove greasy dirt or dust; heating, specifically, the cleaned plate is heated in a heating furnace toan austenite state, and heat preservation is carried out; performing, specifically, after the plate is heated, the plate is quickly transferred to a female die of a thermoforming die, and an edge pressing slide block drives a conical edge pressing ring to press the plate for performing; forming, specifically, after preforming, a drawing slider drives a male die to press down for forming, the edgeof the plate or the semi-finished product is formed into a vertical edge according to a certain curvature along a certain curve, so that forming is completed; punching, specifically, the material is put into a flanging and punching die to be subjected to flanging and punching; heat treatment, specifically, heat treatment is carried out on the thermoforming piece; and trimming and shaping, specifically, the material is put into a trimming die for trimming, and put into a shaping die for shaping. The hot stamping forming process is simple in process steps and operation, easy for achieving mechanization and automation, and suitable for batch production.

Description

technical field

[0001] The invention relates to the technical field of hot stamping forming, in particular to a hot stamping forming process for preparing a driving pulley actuator cylinder for a vehicle. Background technique

[0002] Hot stamping forming technology is a part processing method. Using the principle of metal thermoplastic forming, the blank is first heated to a certain temperature, and then stamped and quenched with a stamping machine in the corresponding mold to obtain the desired shape and realize it at the same time. A material forming method of phase transformation of metal materials. The hot forming process can improve the internal structure of the metal after the plastic deformation of the sheet metal under the premise of low material consumption, the strength of the stamping part is improved, and the parts are light in weight and good in rigidity; forming at high temperature has almost no springback, Higher dimensional accuracy is obtained, the size of...
