A mold for side punching of U-shaped section products

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 used for side punching of U-shaped cross-section products. Background technique [0002] The output of U-shaped cross-section car guide rails is relatively large, and many require side punching. At this stage, most of the U-shaped cross-section car guide rails are punched on the side by drilling and milling machines, which makes the production efficiency low. Inconvenient, the product hole has low dimensional accuracy, and there are many burrs around the hole. The surface of the product is easily scratched during the production process. In addition, customers have high requirements for product size and surface. In order to solve the above problems, a design for A mold for punching the side of U-shaped section products. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a mold for side punching of U-shaped se...
