Stamping mold and stamping method

Abstract

The invention provides a stamping mold and a stamping method, and relates to the technical field of stamping. The number of forming procedures is reduced, and the forming quality is improved. The stamping mold comprises an outer pressing mechanism, an inner pressing mechanism and a forming mechanism. The outer pressing mechanism comprises an outer sliding block, the inner pressing mechanism comprises an inner sliding block, due to the fact that the inner sliding block and the outer sliding block move at the same time and are opposite in motion direction, when the inner sliding block and the outer sliding block move, the outer sliding block and the inner sliding block can be attached to the outer wall and the inner wall of the raw material at the same time, synchronous covering of the innerwall and the outer wall of the product can be achieved, and the number of the forming procedures can be reduced. Due to the fact that the inner wall and the outer wall are covered at the same time, when the raw material is fixed and subject to shape supporting, action force can be exerted to the inner wall and the outer wall of the raw material evenly, deforming of the raw material in the vertical direction can be avoided, and the forming quality is improved.

Description

technical field [0001] The invention relates to the technical field of stamping, in particular to a stamping die and a stamping method. Background technique [0002] In the field of sheet metal stamping, a product with ring features (such as figure 1 Shown) in the molding process, it is necessary to realize the inner wall and the outer wall of the product on the ring surface in the horizontal direction. figure 2 As shown), while fixing the support shape, it is necessary to simultaneously realize the roll forming on the upper and lower end faces of the product in the vertical direction (such as image 3 As shown), due to the limitation of the molding structure, it is difficult to simultaneously cover the inner and outer walls of the product, so multiple processes are required to form step by step, not only the molding process is cumbersome, but also the quality of the molding is difficult to guarantee.
