technical field

The utility model relates to the technical field of stamping equipment, in particular to a non-waste multi-station continuous feeding die. the

Background technique

At present, automotive metal stamping dies are an industrial product that shapes materials in a specific structural form in a certain way, and it is also a production tool that can produce industrial product parts with certain shape and size requirements in batches. These industrial products must be shaped by molds. The high precision, high consistency, and high productivity of parts produced by molds are unmatched by any other processing methods. Therefore, molds determine the quality of products to a large extent. the

The so-called stamping dies can be divided into three categories according to the structure: single-engineering dies, compound dies, and continuous dies. The first two types require more manpower, resulting in poor economic benefits. Continuous dies can be produced in large quantities and can improve production efficiency. The mold usually adopts the nesting process with overlapping edges. This nesting mold with overlapping edges is composed of upper mold base, lower mold base, upper backing plate, upper splint, stop plate, upper stripping plate, lower template, lower pad Plate, lower pad, lock plate, punch, inner guide post, outer guide post and spring. The end face is provided with a lower formwork, and the upper die base is horizontally arranged above the lower die base, and the lower end of the upper die base is provided with a punch, a spring and an outer guide column, and the punch, spring and inner guide column pass through the upper backing plate, the upper The splint is matched with the upper plate, and the lower end of the upper plate is provided with an inner guide column, and the inner guide column is connected with the upper plate, the lower formwork and the lower plate in turn, and the upper end of the lower plate is provided with an outer guide column, and the outer guide The column is connected with the lower formwork, the upper stripping plate and the stop plate in turn, and the lower end surface of the upper stripping plate is provided with an upper punch insert, a chute forming punch insert and a waste punching recess from the rear end to the front end. Die inserts, the upper end surface of the lower template corresponds to the upper punch inserts, the inclined groove forming punch inserts and the waste punching die inserts are sequentially provided with the lower die inserts and the inclined groove forming die inserts The disadvantage of punching die inserts with scraps is that the width of the laps in this layout process with laps is usually 1.2-1.5 times the thickness of the material, resulting in waste of raw materials. the

However, the existing waste-free molds can only produce products with simple shapes and low precision requirements. So far, there is no mold with novel structure, guaranteed product appearance and dimensional accuracy, improved production efficiency, and long mold maintenance cycle. . the

Contents of the invention
