A short-process hot stamping production line equipment and its production process

Abstract

The invention discloses short-process hot stamping forming production line equipment and a production technology thereof. The production line equipment comprises a ceramic pinch roller set, a roller hearth furnace, a conveying roller set, a feeding robot, a hydraulic machine system and a discharging robot which are sequentially arranged from the feeding direction to the discharging direction. Rapid heating devices are arranged between adjacent ceramic pinch rollers in the ceramic pinch roller set. The production technology includes the steps that a blank is put on the ceramic pinch rollers and then conveyed along with the ceramic pinch rollers, and the rapid heating devices are used for rapidly heating and the warming the blank; and afterwards, the blank enters the roller hearth furnace to be heated, and the heated blank is pinched to a mold station of the hydraulic machine system through the feeding robot for hot stamping forming. According to the short-process hot stamping forming production line equipment and the production technology thereof, the mode of combining rapid heating with roller hearth furnace heating is adopted, through the rapid warming means of the rapid heating devices, the technical purpose of shortening the heating process of the blank is achieved, the floor area of the roller hearth furnace is decreased, and the manufacturing cost of heating equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of hot stamping forming, in particular to a short-flow hot stamping forming production line equipment and a production process thereof. Background technique [0002] Hot stamping forming technology is a new forming technology, which is used to improve the plastic forming ability of high-strength steel plates, so as to ensure the dimensional accuracy of stamping parts and improve the strength level of stamping parts. At present, hot stamping forming technology has become a popular technology in the high-strength steel auto parts manufacturing industry. Generally, in the hot stamping process, the billet is heated by roller hearth furnace heating. Its main advantage is that it is suitable for blanks of different shapes after laser cutting. even heating. However, due to the limitation of the heating speed in the heating process of the roller hearth furnace, the production efficiency can only be improved by incr...

AI Technical Summary

Problems solved by technology

[0004] To sum up, there are two main problems in the traditional roller hearth furnace heating process and production line: first, the production line process is long, mainly because the heating section (roller hearth furnace) occupies too much area, which greatly increases the investment cost, and The energy consumption remains high; second, the roller hearth furnace is mainly aimed at aluminum-silicon-coated plates, which further increases the cost of the product. At the same time, non-coated plates cannot be used for production and processing, and the cost advantage of non-coated plates cannot be effectively realized. use
