Metal stamping technology and metal stamping die

Abstract

The invention belongs to the technical field of stamping, and particularly relates to a metal stamping technology and a metal stamping die. The metal stamping die comprises a top plate, a pressing plate, a bottom plate, a power unit and a lubricating unit. The power unit comprises an upper die, a lower die, and a pressing column. The lubricating unit comprises a rack, a gear and an oil brush. Theoil brush is slidably connected with the interior of a cavity through a spring, the top end of the oil brush penetrates to the surface of the lower die, and a first supporting rod is arranged on the side wall, close to the gear, of the oil brush. Through the cooperation of the top plate, the pressing plate, the bottom plate, the power unit and the lubricating unit, the surface of the lower die iscovered with a layer of lubricating oil, so that the demolding resistance is reduced, the stamping quality of a blank is guaranteed, and great convenience is brought to workers. Besides, as the gear continues to rotate, a push rod no longer generates pushing force on the first supporting rod, so that the oil brush is reset under the elastic force of the spring, and the oil brush is prevented fromhindering and affecting the stamping process.

Description

technical field [0001] The invention belongs to the technical field of stamping processing, in particular to a metal stamping process and a metal stamping die. Background technique [0002] Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. Among the steel products in the world, 60-70% are plates, most of which are stamped into finished products. The body, chassis, fuel tank, radiator fins of the car, the steam drum of the boiler, the shell of the container, the iron core silicon steel sheet of the motor and electrical appliances, etc. are all stamped. There are also a large number of stamping p...

AI Technical Summary

Problems solved by technology

The invention has the advantages of simple structure, short processing period and low cost, and ordinary standard strips can produce products meeting the demand through the stamping and extruding process of the stamping die; Problem: During the bending process of the metal plate, the metal plate is easily stuck on the inner wall of the lower mold, which increases the difficulty of demoulding after the blank is formed, and even causes damage to the surface of the mold and the blank, which affects both The overall service life of the mold reduces the stamping quality of the blank
