According to the high-precision convex part machining method based on heating stamping, the related hot stamping equipment comprises a workbench, a stamping table is mounted on the workbench, a heating coil is wound outside the stamping table, a stamping convex mold is fixedly mounted on the top of the stamping table through bolted connection, an adjusting scale is mounted on one side of the stamping convex mold at the top of the stamping table, scale marks are carved on the adjusting scale, the tail end of each scale line is carved with a correction point, one side of the stamping table is further fixedly provided with a lead screw and a sliding rail, thesliding rail is parallel to the lead screw, a power box is mounted on the sliding rail, the side surface of the power box is provided with a translation block, and the translation block is placed onthe lead screw. According to the invention, high-precision continuous hot stamping operation can be achieved, the stamping machining precision is guaranteed while the stamping operation efficiency isimproved, and high-precision rapid convex part stamping is achieved.

Description

technical field [0001] The invention relates to the field of mechanical processing, more specifically, to a processing method for high-precision convex parts based on heating stamping. Background technique [0002] Hot stamping forming technology is a new process that utilizes the characteristics of rapid increase in plasticity and ductility and rapid decrease in yield strength of metals at high temperatures to form parts on hot stamping dies, and at the same time use die cooling and quenching to achieve ultra-high strength. Using hot stamping technology can not only overcome the defects of traditional high-strength steel plate forming difficulties and low dimensional accuracy of parts, but also significantly improve the safety and comfort of automobiles, reduce vehicle weight, and reduce gas emissions. [0003] Because of these advantages, the hot stamping process is currently a research hotspot in automobiles, steel and related fields. At present, in the processing of she...

Problems solved by technology

At present, in the processing of sheet metal, plane stamping has been able to meet extremely high precision requirements, but for direct stamping of convex parts, its high precision cannot be guaranteed

[0004] Since the stamping die is in a state of intermittent stress during use, it is prone to slight deviation during the long-term stress process, and the accumulation of time will reduce the precision of the stamping workpiece

It will even affect the service life of precision molds and increase the cost of stamping processing
