Large-size shallow-drawing stamping part progressive die

Abstract

The invention discloses a large-size shallow-drawing stamping part progressive die in the technical field of stamping machine tool dies. The large-size shallow-drawing stamping part progressive die comprises an upper die and a lower die which are arranged correspondingly, wherein a stripper plate of the upper die and a lower die plate of the lower die are correspondingly provided with multiple stations, two stations at the front end in the upper die are respectively and correspondingly provided with cut punches, the upper ends of the cut punches are fixed on a punch holder, the lower ends of the cut punches extend into punch holes passing through a stop plate and the stripper plate from top to bottom, lower cuts corresponding to the cut punches are arranged on the lower die plate, each cut punch consists of multiple sections of unit punches which are arranged at intervals in the width direction of the die, and the unit punches corresponding to the two stations at the front end are arranged in a staggered manner and cover a shallow-drawing area of a material tape in the width direction of the die. Before the material tape is subjected to shallow drawing, a seam is cut on the material tape by the device, thereby avoiding harmful effects on other stations caused by the deformation of the material tape, and further improving the processing accuracy and production efficiency. The device is used for processing large-size shallow-drawing sheets.

Description

technical field [0001] The invention relates to a processing die used on a stamping machine tool, in particular to a processing die used for shallow drawing sheet metal parts. Background technique [0002] With the rapid development of the economy and the continuous improvement of product technology, household appliances such as LCD TVs and computers have been popularized in every household, and the market competition has become increasingly fierce. This requires manufacturers to continuously reduce product costs and enhance the core competitiveness of products on the basis of ensuring product quality. This also puts forward higher requirements on the molds for producing parts: it is necessary to ensure product quality, improve production efficiency, and reduce the production cost of a single product. [0003] There is a large-sized shallow-drawn sheet metal part used inside the LCD TV. Due to its large size, including shallow-drawing, such large-sized sheet metal workpiece...
