Composite two-way side cutting structure and punching method

Abstract

The invention relates to a composite two-way side cutting structure and a punching method, and belongs to the technical field of dies. The side cutting structure comprises a sliding block, a double-edge side cutting blade, a first slotting tool and a second slotting tool, wherein the sliding block is installed on a lower die and can slide on the lower die in the Y direction; the double-edge side cutting blade is mounted on the sliding block and can slide on the sliding block in the X direction; the first slotting tool is mounted on an upper die and drives the sliding block to move on the lowerdie during die assembly; the second slotting tool is mounted on the upper die and drives the double-edge side cutting blade to move on the sliding block during die assembly; and a first elastic resetstructure and a second elastic reset structure are mounted between the sliding block and the lower die and between the double-edge side cutting blade and the lower die respectively. By means of the structure, the composite two-way side cutting structure has the advantages of being simple and stable in structure and small in occupied die space, the appearance and the size of strip stretching and cutting forming of a continuous die are well guaranteed, moreover, accumulated errors during product machining can be reduced, and the qualified rate of products is increased.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a composite bidirectional side-cutting structure and a punching method. Background technique [0002] The current mold production technology is becoming more and more mature, and more and more products are speeding up the production rhythm in order to increase production capacity. Most sheet metal parts are produced by continuous molding. For products with stretch forming such as air conditioner chassis and electrical box cover, the conventional continuous die front cutting method is adopted due to the structural restrictions of the continuous material when the final part is cut. However, due to this cutting method, after stretching, the upper and lower molds in the cutting step avoid space and there is no pressure material, resulting in large burrs at the four corners, obvious tearing of the gap, easy scratching of hands, and protruding sharp corners when the product ...

Problems solved by technology

However, due to this cutting method, after stretching, the upper and lower molds in the cutting step avoid space and there is no pressure material, resulting in large burrs at the four corners, obvious tearing of the gap, easy scratching of hands, and protruding sharp corners when the product is cut. The final machine assembly When the outer top of the panel is abnormal, the part screening fails, which greatly affects the quality of the mold

[0003] In the single-process mold, the conventional side-cutting structure can only complete side-cutting in one direction, and the final molding size of the product needs to be divided into multiple steps of side-cutting knives; but there must be certain installation errors and product positioning in the molding process of each step Errors, which will lead to large cumulative errors, poor part size consistency, and a substantial increase in production costs

[0004] In short, the continuous mold usually has more defects in the product incision due to the front stamping. Although the single-process mold that can realize side cutting can solve the problem of incision defects, it can only complete the side cutting of one process at a time, which is inefficient. Product production needs The cooperation of multiple single-process molds is completed, which leads to the defects of large accumulated errors, large space and volume of multiple single-process molds, and increased costs.
