A shielded grounding card card body mold

Abstract

The invention relates to a shielding grounding card body mold, which is composed of an upper mold and a lower mold. The innovation point is that the lower mold includes a die and a lower mold base. There is a feeding guide block, and the upper surface of the die is provided with a circular blanking hole, a waist-shaped blanking hole, a dumbbell-shaped blanking hole and a blanking cavity on the moving path of the copper strip; the upper mold includes an upper mold seat arranged in sequence , backing plate, fixed plate, unloading plate, the fixed plate is equipped with round hole upper punch, waist shaped hole upper punch and broken material punching; the fixed plate is drilled with a number of stepped through holes, the stepped through holes are installed with screws whose lower end is threadedly connected with the unloading plate, and a spring pad is installed between the fixed plate and the unloaded plate. The advantages of the present invention are that the upper and lower molds can realize the blanking and punching of the copper strip at one time, avoiding oil stains during the transfer process, thus eliminating the need for pickling, reducing the scrap rate of products, and improving production efficiency.

Description

technical field [0001] The invention relates to a mold, in particular to a shielding grounding card body mold. Background technique [0002] The grounding card is used to introduce the induction current of the feeder or shielding wire of the electrical equipment into the grounding network, so as to prevent the induction current generated by lightning from damaging the equipment. The existing non-adhesive-free grounding cards mainly include general-purpose, spring-type, etc., such as figure 1 As shown, the body of the universal shielded grounding card is a rectangular metal sheet 20, one end of the metal sheet 20 has two bolt connection holes 21, and the other end has a waist-shaped hole 22 corresponding to the two bolt connection holes. The blanking and punching of the traditional shielded grounding card body are carried out separately. First, the copper strip needs to be punched into small pieces of copper, and then holes are drilled on the copper. Because the process nee...

Problems solved by technology

Because the process needs to be transported, the copper sheet is often covered with oil and needs to be pickled to improve the surface gloss. However, the thickness of the copper sheet is about 0.3mm, and it is easy to bend during pickling and cause scrapping. The qualified rate of the product is low, and Low production efficiency and high manufacturing costs
