Problems solved by technology

[0005] However, because the outer mold is a hard mold and the inner mold is a soft mold, the above-mentioned composite mold has poor bearing capacity during work. Once the impact force is large, the outer mold is likely to be broken when the inner mold is greatly deformed, and the use is stable. The stability is not high, and there is a rope between the inner mold and the outer mold of the mold, the structure is more complicated, and the manufacturing cycle of the mold is longer

Embodiment 1

[0035] A manufacturing process of a prestressed composite mold, the process comprises the following steps:

[0036] A. Mandrel bar material: the cold-work die steel billet is processed by multi-directional forging to make a long strip-shaped mandrel 1 bar with a set cross-section. Among them, it is necessary to forge multiple sides of the bar, so that Obtain cross-section is the mold core 1 of the long bar shape of ellipse (the material of mold core 1 can also be hot working die steel, the shape of the cross section of mold core 1 can also be rhombus or rectangle or square, certainly can be regular polygon or geometric shape);

[0037] B. Composite casting: The outer mold 2 material is cast to cover the outside of the mold core 1 bar through the ordinary composite casting process, so that two materials with different properties, the outer mold 2 material and the mold core 1 bar, are firmly combined into an integrated structure The composite bar material, wherein, the material...

Abstract

The invention provides a technology for manufacturing a prestress compound die and belongs to the technical field of mechanical dies. The technology for manufacturing the prestress compound die solves the problems that an existing compound die is poor in bearing capacity, low in stability and long in manufacturing period. The technology for manufacturing the prestress compound die comprises the following steps that A a die core is made of a bar, B compound casting is conducted, C annealing treatment is conducted, D blanking and cutting are conducted, and E quenching treatment is conducted. The technology for manufacturing the prestress compound die has the advantages of being capable of effectively shortening the manufacturing period of the compound die and enabling the carbon content to be low, environmentally friendly, capable of saving energy and reducing consumption, good in economic benefit and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical moulds, and relates to a composite module, in particular to a manufacturing process of a prestressed composite mould. Background technique [0002] At present, the known hot forging die structure is directly manufactured from a die material as a whole, and the manufacturing process generally includes rough machining of the die steel billet, heat treatment, finishing and nitriding and other surface treatments. The traditional module is a monolithic structure with a low service life; if the hardness is high and the brittleness increases, there is a greater risk of early cracking, so the hardness can only be sacrificed to increase the toughness to meet the use requirements. Because hot forging is processed under high temperature and high pressure, the requirements for molds and mold materials are very strict. In order to improve the quality and service life of molds, mold materials need to be comp...
