Abstract

This utility model provides a punching and bending die with a slanted sliding die, including an upper die (1) and a lower die (2). The lower die of this utility model is equipped with a slanted sliding seat, a slanted sliding die, a die template, a lower die carrier plate, and a demolding spring. During operation, the upper die presses down, and workpiece A slides from top to bottom into the die groove of the die template along with the slanted sliding die. The punch of the upper die presses down to bend workpiece A into workpiece B. Afterward, the upper die returns to its original position. Under the action of the demolding spring, the slanted sliding die pushes workpiece B upward and moves to the left while disengaging it from the die template, causing workpiece B to simultaneously disengage and separate from the slanted sliding die and the die template. This technical solution enables the punching and bending die to process sheet metal workpieces A to B with protruding flange holes at the 90° inner bending surface, thereby reducing workload, improving production efficiency, and avoiding workpiece damage.
