Abstract

The invention relates to an insert splicing type die. The insert splicing type die comprises an outer ring die, an inner ring die and connecting keys, wherein the inner ring die is arranged in the outer ring die and is connected to the outer ring die through the connecting keys; the outer ring die is of a ring shape and is provided with a first groove and a second groove, wherein the first groove and the second groove are symmetrically formed; the inner ring die is round and is provided with a first gap and a second gap, wherein the first gap and the second gap are symmetrically formed, and two guide rod holes are formed; the connecting keys are triangular, and the grooves of the outer ring die and the gaps of the inner ring die correspond and are connected through the connecting keys. The outer diameter of the outer ring die is D, the inner diameter of the outer ring die is d, the outer diameter of the inner ring die is d, and the D / d value ranges from 1.6 to 2.5. A lower die is made of high-speed steel. According to the insert splicing type die, the problem that the lower die is short in service life due to being easily cracked is solved, the service life of the lower die is prolonged, and the work efficiency is improved.

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...
