Die for punching of side edge of product with U-shaped section

Abstract

The invention relates to a die for punching of a side edge of a product with a U-shaped section, comprising a male die, a female die and a lower die plate, wherein a lower die is arranged at the upper end of the lower die plate, a sliding block is arranged at one side of the lower die, the female die is arranged at the upper end of the lower die, a through hole is vertically formed in one end of the female die, the other end of the female die stretches into the side wall of the sliding block to be fixed, the lower die plate is connected with the sliding block by a round-wire spiral spring, the sliding block and the lower die are connected with a fixed plate arranged above the female die by an unloading guide pillar, an unloading plate capable of sliding along the unloading guide pillar is arranged between the fixed plate and the female die, the male die is arranged in the fixed plate, the lower end of the male die slides in a movable slot of the unloading plate, an upper die plate is arranged at the upper end of the fixed plate, an unloading screw is in sliding connection in the upper die plate, and the lower end of the unloading screw penetrates through the fixed plate to be connected with the unloading plate. The die can improve the production efficiency and ensure the dimension precision and surface requirements of products.

Description

technical field [0001] The invention relates to the field of auto parts production equipment, in particular to a mold for punching holes on the sides of U-shaped section products. Background technique [0002] The U-shaped cross-section automobile guide rail has a large output, and many require side punching. At this stage, most of the U-shaped cross-section automobile guide rails are punched on the side by drilling machines and milling machines, which makes the production efficiency of the product low. Inconvenient, the dimensional accuracy of the product hole is low, there are many burrs around the hole, the product surface is easy to scratch during the production process, and the customer has high requirements for the product size and surface. In order to solve the above problems, a The mold for punching holes on the side of U-shaped cross-section products. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mo...
