Embodiment Construction

[0022] Such as figure 1 , 2 As shown, the present invention provides a support mechanism for hot stamping dies of ultra-high strength steel plates. The support mechanism for hot stamping dies of ultra-high strength steel plates includes: die body 1, support block 2, guide sleeve 3, and return screw parts 4. Spring 5, cylinder 6, upper mold insert 7, upper mold body 8, and workpiece 9; said holding block 2 has a water channel 21 on it, which is provided by a water pipe introduced outside the mold body 1 Circulating water cooling. The supporting block 2 is made of hot work die steel specially used for hot stamping. In the stamping process, the supporting block 2 participates in the forming of the workpiece; after the stamping completes the pressure holding and quenching stage, the supporting block 2 and the upper die insert 7 work together to quench the workpiece 9 under a certain pressure.

[0023] The guide sleeve 3 is installed on the mold body 1 . The wall surface of the...

Abstract

The invention provides a special water-passage-containing support mechanism for an ultra-high-intensity steel plate hot stamping mold. The support mechanism consists of a mold body 1, a support block 2, a guide sleeve 3, a material return screw component 4, a spring 5, an air cylinder 6, an upper mold embedding block 7, an upper mold body 8 and a workpiece 9. In the stamping process, the support block 2 takes part in the workpiece forming; after the stamping completion, the support block 2 and the upper mold embedding block 8 simultaneously act, and the quenching cooling is realized on the workpiece 9 at a certain pressure; the material return screw component 4 and the guide sleeve 3 simultaneously act, and the guide effect is provided for the support block 2; and the material return screw component 4, the spring 5 and the air cylinder 6 simultaneously act, and the propping and return actions of the support block 2 are realized. The support mechanism provided by the invention realizes the stable and reliable support and return actions and meets the special requirements of the ultra-high-intensity steel hot stamping process on the support mechanism.

Description

technical field [0001] The invention belongs to the technical field of metal stamping, and relates to a super-high-strength steel plate hot-stamping die, in particular to a special-purpose water channel support mechanism for the ultra-high-strength steel plate hot-stamping die. Background technique [0002] In the automobile industry, people are paying more and more attention to reducing energy consumption and reducing exhaust emissions to protect the environment, while at the same time they are required to improve the passive safety performance of automobiles. An important means of achieving this goal is to reduce the weight of the car body without losing structural strength. At present, one of the main ways to realize the lightweight of the car body is to replace the traditional steel plate material with ultra-high strength steel plate. However, the forming force required by the traditional cold stamping forming method of high-strength steel plates is very high, and the s...
