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

Embodiment 1

[0047] see figure 1 , a high-precision convex processing method based on heated stamping, the specific steps are as follows:

[0048] S1. Die adjustment: adjust the stamping die used for hot stamping, correct its positional relationship, and fix it to prevent accidents that cause stamping offset;

[0049] S2. Plate preheating: place the plate to be stamped in the preheating device for preheating to reduce the heating power consumption during hot stamping operations, and at the same time reduce the time required to heat the plate before stamping and improve the work of hot stamping processing efficiency;

[0050] S3. Plate feeding: transport the preheated plate to the stamping die, and continuously feed the plate to realize multiple stamping of the same plate at different positions, and improve the utilization efficiency of the plate;

[0051] S4. Continuous stamping: After the preheated plate is transported to the stamping die, during the continuous feeding of the plate, the...

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...
