Abstract

The invention provides a two-way U-shaped bending die and belongs to the field of stamping dies. The two-way U-shaped bending die comprises a lower die seat and an upper die seat. A female die is arranged on the lower die seat, two forming grooves are symmetrically formed in the left side and the right side of the female die, male die mechanisms are symmetrically arranged on the portions, on the two sides of the female die, of the lower die seat and comprise male die seats and forming male dies, the male die seats and the lower die seat are fixedly connected, the forming male dies and the male die seat are connected in a sliding manner, and a tapered wedge for pushing the forming male dies to slide is arranged on the upper die seat. When workpieces are machined, the two forming male dies extrude the workpieces in the left direction and the right direction respectively, under cooperation of the forming grooves, the two workpieces are machined in a U shape simultaneously, the machining speed is effectively increased, and production efficiency is effectively improved. The two-way U-shaped bending die has the beneficial effects that the design structure is simple and reasonable, the forming speed is high, production efficiency and machining accuracy are high, the service life is long, and practicality is high.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a bidirectional U-shaped bending die. Background technique [0002] Stamping is a processing method that uses a stamping die installed on a press to apply pressure to raw materials under normal temperature conditions to separate or plastically deform the raw materials to obtain the desired part shape. Bending parts are one of the most numerous stamping parts in the manufacture of modern industrial products, automobiles, electrical appliances, instruments and tools, among which U-shaped bending parts are the most common type of bending parts, most of which are made of U-shaped bending dies to process. However, the existing U-shaped bending die can only process one workpiece at a time to obtain a U-shaped part, which has the problems of slow processing speed and low production efficiency. Contents of the invention [0003] The present invention provides a two-way U-shaped bending d...
