Description

Stamping die is used in sheet metal processing

Technical Field

The utility model relates to a stamping equipment technical field specifically is a stamping die is used in sheet metal processing.

Background

The metal material is a material having properties such as luster, ductility, easy electrical conductivity, and heat transfer. Generally divided into ferrous and non-ferrous metals. Ferrous metals include iron, chromium, manganese, etc., with steel being the basic structural material, known as "industrial skeleton". Due to the progress of science and technology, the wide application of various novel chemical materials and novel non-metallic materials has led to the increase of the substitute of steel and the relative decrease of the demand for steel, and the flat rectangular material plate with standard size is made into a metal plate, and the stamping die is a special process equipment for processing the material (metal or non-metal) into parts (or semi-finished products) in the cold stamping process, which is called as a cold stamping die (commonly called as cold stamping die). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part.

Through retrieval, the patent publication No. CN113523081A discloses a stamping die for processing metal plates, which comprises a cushion box, wherein waste material openings are formed in two ends of the top surface of the cushion box, blocking plates are fixed on opposite sides of the two waste material openings, a first installation box is fixedly installed at the center of the top surface of the cushion box, a lower template is fixedly embedded in the top surface of the first installation box, discharging plates in a U-shaped structure are symmetrically hinged to two sides of the first installation box, a abdicating mechanism is arranged between the discharging plates and the first installation box, and turnover mechanisms for overturning the discharging plates are arranged on two sides of the discharging plates; the device can realize in time carrying out the drainage to the leftover bits of panel punching press and retrieve, prevents that the piece from splashing and influencing panel stability and part safety, is favorable to maintaining good punching press environment, and need not artifical manual touching metal sheet and unload, has improved the security among the stamping process.

In the prior art, CN113523081A lacks a detection structure for the distance between the upper die and the lower die during use, which easily causes the phenomenon that the plate is not stamped in place, thereby causing the dimension of the processed plate to deviate and affecting the processing quality of the plate.
