Hot-punching forming process

Abstract

The invention discloses a hot-punching forming process which comprises the steps of (1) levelling and punching a raw material steel coil through a leveler so as to obtain a required workblank slice; (2-1) dividing holes and edges in products into two grades according to the accuracy requirement, designing a hot forming mold, and designing a punch head and a cutter block for forming holes and edgesat one grade in the hot forming mold; (2-2) after sufficiently heating the workblank slide in a heating furnace for a setting time, using a mechanical clamping jaw for transferring the heated slice into the hot forming mold, and punching the slice into a required shape; (3) cooling; and (4) laser cutting: utilizing a laser cutting machine for heating a workpiece, cutting to obtain a hole and an edge in the other grade accuracy, and removing redundant slice parts. According to the hot-punching forming process provided by the invention, without influencing the hot-punching forming efficiency, punching and trimming are added in the hot forming process at the same time, so that the total cutting path for laser cutting in the later process is reduced, the circulation time and the cost of laserare reduced, and the production efficiency is improved.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of workpiece processing technology, and in particular relates to a hot stamping forming technology. [0003] 【Background technique】 [0004] During the production, the blanking production sheet is sent into the heating furnace and heated to above 900 degrees for a period of time, and then transferred to the mold for hot stamping and forming. The produced parts have high yield strength. The production process in the prior art, After hot stamping, wire cutting is used to cut off all the redundant pieces of the product such as holes and edges. On the one hand, the cost of wire cutting is high; on the other hand, there are many parts to be cut and the path is long. Long cycle times lead to low production efficiency. [0005] Therefore, it is necessary to provide a new hot stamping forming process to solve the above problems. [0006] 【Content of invention】 [0007] The main purpose of the present inve...
