Embodiment Construction

[0031] see Figure 1 to Figure 12 , the auto parts integral pre-embedded tube hot stamping die of the present invention, taking the automobile B-pillar parts as an example, the mold comprises a mold die 1 and a punch 2, which respectively have the same structural shape as the automobile B-pillar parts. The corresponding profiles 11 and 21 are T-shaped at both ends; the cooling water pipelines 3 and 4 are arranged in the profiles of the die die 1 and punch 2, and the cooling water pipelines 3 and 4 are connected by the diversion communication grooves 5 and 6. Seal plugs 7, 8 to form two sets of connected cooling water passages with different flow directions; both die die 1 and punch 2 are externally connected with a water inlet joint 12, 22 and a water outlet joint 13, 23, and are connected with the diversion communication groove 5 , 6 are connected; the cooling water pipelines 3 and 4 are bent and arranged with 6-8 branch pipelines 31 and 41 along the direction of the mold sur...

Abstract

The invention discloses an integrated embedded pipe hot stamping die for automobile parts, which comprises a female die, a male die, a water inlet joint, a water outlet joint and a sealing plug, wherein the female die and the male die are provided with profiles corresponding to structures and shapes of the automobile parts respectively. The integrated embedded pipe hot stamping die is characterized in that: cooling water pipelines are embedded in the female die and the male die, and the cooling water pipelines are arranged in a bend mode along with the directions of the profiles in the female die and the male die; and the female die and the male die with the structures have integral cast structures respectively. By adopting the combination of the straight-through pipe and the complex curved pipeline and adopting a cooling system with a shunt communicating groove and the sealing plug, the integrated hot stamping die for the complex automobile parts has simple, reliable and practical structure, the manufacture, use and maintenance costs of the hot stamping die are reduced, and the production cost of hot stamped parts is reduced.

Description

technical field [0001] The invention belongs to the field of stamping and forming of sheet materials, and in particular relates to a hot stamping mold of an integral pre-embedded pipe for automobile parts. Background technique [0002] Hot stamping is a new forming technology developed in the past 20 years. Its technological feature is to heat the Boron steel plate with an original strength of about 400-600Mpa to the austenitic temperature range, quickly move to the mold and press it quickly, and keep it in the press. In the pressed state, the parts are rapidly cooled through the mold to achieve quenching and strengthening, and a martensitic structure and a tensile strength of about 1500Mpa or even higher are obtained. The use of hot stamping parts in the body structure can greatly improve the collision safety of the body, reduce the weight of the body in white, and meet the requirements of the automotive industry for safety, energy saving, environmental protection, and comf...
