A stamping die set and its working method

Abstract

The invention discloses a stamping module and a working method thereof, comprising: a stamping barrel connected with a driving mechanism, a mold cavity below the stamping barrel, the cavity is used for stamping and preparing a shell, a plate is arranged on the surface of the cavity, and the stamping barrel The inner cavity of the inner cavity is provided with an upper pressing plate and a lower pressing plate connected by ropes, and the upper pressing plate and the lower pressing plate can reciprocate and slide in the stamping barrel; the upper surface of the lower pressing plate is provided with a reservoir, which contains non-Newtonian fluid, The lower surface of the lower platen is connected to the stamping head, and at least two sets of pumps are arranged on the lower surface of the lower platen; when the stamping head contacts the plate, the composition ratio of the non-Newtonian fluid is changed by pumping or pumping out the material into the tank, so as to adjust the stamping pressure The strength of the head enables the sheet to be formed quickly without breaking. A stamping die set involved in the present invention performs time-sensitive buffering by setting non-Newtonian fluid in the components of stamping equipment, thereby protecting brittle plates and equipment, and improving the adjustment accuracy of the punching machine.

Description

Technical field [0001] The present invention relates to a mold manufacturing technique and a stamping mold, in particular to a stamping module. Background technique [0002] Stamping is an external force to the plate, strip, pipe, and profiles such as press press and mold, resulting in plastic deformation or separation, thereby obtaining a molding process of workpiece (stamping parts) required for shape and size. Stamping and forging with plastic processing (or stress machining), is known for forging. The stamped blank is mainly hot rolled and cold-rolled steel sheets and steel strips. Among the world's steel, 60 ~ 70% is a plate, most of which are stamped into a finished product. Car body, chassis, fuel tank, heat sink, boiler steam bag, container housing, motor, iron core silicon steel sheet, etc. are all stamping. In instrumentation, household appliances, bicycles, office machinery, living vessels, etc. also have a large number of stamped parts. The mold used in stamping is re...

Problems solved by technology

[0003] However, in the actual use of the die, for the process of processing brittle materials, the conventional buffer spring can no longer provide time-sensitive protection for the brittle plate, and it will cause the plate to break during the stamping process.
