Abstract

The precise multifunctional incremental pressing die includes a lower die, an upper die, an internal guiding mechanism and an outer guiding mechanism. The upper die includes an upper die seat, a convex die back plate, an unloading back plate, and an unloading plate. The lower die includes a lower die seat, a concave back plate and a concave die plate. The outer guiding mechanism includes a large guide pin, a large ball sleeve, a large guide sleeve and a spring. The internal guiding mechanism includes a small guide pin, a small ball sleeve, a small guide sleeve and a spring. The making process features that the unloading plate and the concave die plate are fastened together.

Description

technical field [0001] The invention relates to a high-speed stamping die for producing various lead wires, terminals, connectors, reeds and various hardware parts, and mainly refers to a precision multifunctional progressive stamping die and a manufacturing method thereof. Background technique [0002] Existing stamping dies have some defects in structure and processing technology to varying degrees. For example, in terms of structure, ① Generally, there are only four guide pillars. When the guide pillars wear out and lose precision, the entire mold has to be scrapped; It is extremely inconvenient to maintain; ③The small guide column is fixed on the punch fixing plate, and is slidingly matched with the stripper plate and the concave formwork. The processing technology adopts material preparation→rough machining of milling and drilling pliers→heat treatment→flat grinding→wire cutting→fitter assembly. When the template is wire cutting, each piece is processed separately accor...
