Forging die good in demolding effect

Abstract

The invention discloses a forging die good in demolding effect. The forging die comprises an upper die base and a lower die base, wherein a punch is arranged on the upper die base, and a punching groove is formed in the lower die base; the punch moves in the vertical direction to extend into the punching groove, and a limiting assembly is arranged on the upper surface of the lower die base; the limiting assembly comprises a limiting plate and two limiting blocks contained in the limiting plate, and the two limiting blocks move in the left-right direction and abut against each other to form a limiting ring; the limiting ring sleeves the punch, and limiting columns are symmetrically arranged on the portion, on the two sides of the punch, on the upper die base; limiting grooves correspondingto the limiting columns are symmetrically formed in the portions, on the two sides of the punching groove, in the limiting plate; and one end of each limiting block extends into the corresponding limiting groove, and the limiting columns move in the vertical direction to extend into the limiting grooves and push the limiting blocks to move in the left-right direction. The forging die has the advantages that a forge piece and the die can be quickly separated, and the structure is optimized.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a forging die with good demoulding effect. Background technique [0002] Forging is one of the two major components that use forging machinery to exert pressure on metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging can eliminate defects such as as-cast porosity produced in the metal smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings of the same material. For important parts with high load and severe working conditions in related machinery, forgings are usually used, except for plates, profiles or weldments that can be rolled with simpler shapes. [0003] Forging can be divided into free forging, die forging, ring rolling and special forging. Die forging is furt...

AI Technical Summary

Problems solved by technology

The existing die forging cannot be separated from the forging immediately after forging, and requires manual cooperation and manual demoulding. The process is cumbersome and labor-intensive, and the risk factor is high
