Embodiment Construction

[0021] The specific structure and implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Depend on figure 1 As shown, the present invention provides a thermoforming die with a combined cooling die and a replaceable movable backing plate. The thermoforming die adopts an inverted structure and consists of two parts, an upper and an lower die. Die 4, die backing plate 7, upper die base 8, upper die backing plate 10, nitrogen spring assembly 13, movable backing plate 15 and movable cooling block 19, water guide plate 18, cooling block cover plate 17; It is partly composed of a lower die base 1, a pier dead block 2, a blank holder 3 and a punch 22. The upper die part is installed on the upper slider of the press, and the lower die part is installed on the workbench of the press. During stamping, the high-temperature sheet is located between the upper and lower dies, and the die and die backing plate are fix...

Abstract

The invention relates to a hot forming die with a combined cooling female die and a changeable movable base plate, and belongs to the technical field of super-strength steel plate hot stamping and forming. The hot forming die is of a flip-over type structure, and comprises an upper die portion and a lower die portion. The upper die portion comprises a female die, a female die base plate, an upper die seat, an upper die base plate, a movable base plate, a nitrogen spring component, movable cooling blocks, water guide plates, cooling block cover plates and the like. The lower die portion comprises a lower die seat, bottoming blocks, blank holders, a male die and the like. The main problem of low cooling efficiency caused by uneven cooling and small cooling area is solved. Due to the changeable movable base plate, hot stamping parts with different surface shapes can be formed.

Description

technical field [0001] The invention relates to a thermal forming die of a combined cooling die and a replaceable movable backing plate, which belongs to the technical field of ultra-high-strength steel plate hot stamping forming. Background technique [0002] The formability of ultra-high-strength steel plates is much worse than that of ordinary steel plates, and the deformation ability at room temperature is very poor. It is difficult to form such plates by traditional cold stamping methods; in this context, hot stamping technology for ultra-high-strength steel plates came into being. The characteristic of this new type of hot forming technology is: first, the ultra-high-strength steel plate is heated to the austenitization temperature and held for a period of time to make it evenly austenitized, and then the sheet is quickly transferred to a cooling system designed Stamping in the mold and rapid cooling and quenching to obtain a new forming technology for ultra-high-stren...
