Problems solved by technology

The use of mosaic structure makes the design and manufacture of the mold more complicated, more difficult, more costly, and longer cycle time
In practical application, since the cooling pipe of the mold also adopts an inlaid structure, if no effective anti-leakage treatment is taken, the displacement of the mold insert will change under the action of the forming force during the forming process, which will easily lead to the displacement of the cooling pipe Changes that cause coolant to leak, thereby compromising the life of the mold and the strength of the mold

Abstract

The invention discloses a high strength steel plate hot stamping die for automobile parts. The high strength steel plate hot stamping die for the automobile parts mainly consists of a male die body (a male die and a male die connecting fixing plate), a female die body (a female die and a female die connecting fixing plate), blank holders, cooling pipelines, connecting devices, positioning devices, U-shaped connecting hoses and pipe joints. The male die, the male die connecting fixing plate, the female die, the female die connecting fixing plate and the blank holders are respectively manufactured, and grooves used for fixing the cooling pipes are respectively processed. The cooling pipelines are manufactured into shape-following cooling pipelines which are consistent with the shape trends of the parts by adopting copper pipes, are respectively arranged in the grooves respectively arranged in the male die body, the female die body and the blank holders, and are externally connected with a master cooling pipeline through the U-shaped connecting hoses and the pipe joints to form a cooling closed loop. The hot stamping die disclosed by the invention is simple and compact in structure and convenient in maintenance, is reliable and practical, can be used for evenly and rapidly cooling the parts during a stamping process and is in favor of enhancing the working stability per se and prolonging the service life per se.

Description

Technical field: [0001] The invention relates to a high-strength steel plate hot stamping die for automobile parts, belonging to the technical field of hot stamping forming. Background technique: [0002] Since the beginning of the 21st century, due to the development of the world economy and society and the improvement of national living standards, the requirements for energy saving, comfort and safety of automobiles are also getting higher and higher. Faced with this situation, various automobile manufacturers focus on sustainable development strategies and use automobile lightweight technology to achieve energy saving and emission reduction. However, in order to realize the lightweight of the car, in addition to optimizing the design of the car body structure, it is also possible to use lightweight materials to manufacture car body components. High-strength and ultra-high-strength steel plates have become one of the most important means of automobile lightweight due to t...
