Abstract

The invention relates to an automobile part processing die, and in particular relates to a stamping die for an intra-threshold connection plate of an automobile. The stamping die for the connection plate in the automobile threshold is characterized by comprising an upper die plate and a lower die plate, wherein a male die is fixed on the lower part of the upper die plate through a bolt; a cushion block is fixed on the upper part of the lower die plate through a bolt; a female die is arranged on the upper part of the cushion block; the lower die plate, the cushion block and the female die are fixedly locked through a safety bolt; and a T-shaped depressed cavity is arranged at the middle part of the female die. The stamping die is made of cast iron. The stamping die for the intra-threshold connection plate of the automobile is tightly connected and relatively reliable and the stamping efficiency is high.

Description

technical field [0001] The invention relates to a mold for processing automobile parts, in particular to a stamping mold for an inner connecting plate of an automobile door sill. Background technique [0002] The door sill inner connecting plate of a small car is mainly formed by stamping. In the existing stamping processing equipment, the connection between the punch (or die) and the upper template (or lower template) is not precise enough, and it is prone to detachment or deviation. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a stamping die for an inner connecting plate of an automobile door sill with reliable connection. [0004] The technical scheme that the present invention adopts is as follows: [0005] The stamping die for the inner connection plate of the automobile door sill is characterized in that it includes an upper template and a lower template, the lower part of the upper templ...
