Abstract

The invention relates to an insert splicing mold, which comprises an outer ring mold, an inner ring mold and a connecting key. The inner ring mold is placed in the outer ring mold and connected by the connecting key; Groove, the second groove, the groove is opened symmetrically; the mold of the inner ring is circular, has the first notch, the second notch, the notch is opened symmetrically, and there are two guide rod holes; the connecting key is triangular, and the mold of the outer ring is concave The groove corresponds to the notch of the inner ring mold and is connected by a connecting key. The outer diameter of the outer ring mold is D, the inner diameter of the outer ring mold is d, the outer diameter of the inner ring mold is d, the value of D / d is in the range of 1.6 to 2.5, and the lower mold is made of high-speed steel. The invention solves the problem that the lower mold is easy to crack and has a short service life, improves the service life of the lower mold and increases the working efficiency.

Description

technical field [0001] The invention relates to the field of mechanical forging, in particular to an insert splicing die. Background technique [0002] As a kind of forging equipment, the stamping machine is often widely used in the mold casting process. It relies on the stamping machine and the mold to exert external force on the plate-shaped strip, so that the strip can be plastically deformed or separated, so as to obtain the stamping of the required shape and size. pieces. Stamping includes two kinds of deformation process and separation process. The separation process is also called blanking. Its purpose is to separate the stamped parts from the strip along a certain contour line, while ensuring the quality requirements of the separation section. The purpose of the forming process is to make the strip plastically deform without breaking the billet to make a blank of the required shape and size, but the use of the punching machine is very dangerous. The punching machine...
