Abstract

The utility model provides a hot forging mould which is mainly used in a shaping mould of a high speed hot press forge shaping station. The hot forging mould comprises a mould body, wherein the inner cavity of the mould body is provided with a mosaic mould integrating the mould body into a whole. The mosaic mould is contacted with a forgeable piece, and adopts alloy material different from the mould body. Because the mould is the mosaic mould, the inner cavity of the mould contacted with the forgeable piece adopts the material with higher rigidity, other parts of the mould adopt common mould materials with better toughness, thereby simultaneously meeting property requirements of heat and abrasion resistant and toughness. Meanwhile, because the part of the mould contacted with the high temperature forgeable piece is smaller, the adopted special heat and abrasion resistant materials are little, especially, the especial materials can be locally replaced after being worn by using for a long time according to specific conditions, compared with the whole hot forging mould, the mosaic mould has perfect property, saves the material cost, lowers the manufacture cost, and obviously improves the quality and the service life of the mould.

Description

A kind of hot forged mould

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of hot forging forming mould.

Background technology

At present, known hot forged mould structure is directly made by a kind of mold materials is whole, and manufacturing process roughly is the roughing of mould steel material base, heat treatment, surface treatments such as mill processing and nitrogenize.Forge hot is owing to be the processing of carrying out under HTHP power, and very harsh to the requirement of mould and mold materials thereof etc., for the quality and the service life of improving mould, mold materials needs precious metals such as nickel, tungsten, molybdenum and constitutes, and its price is very expensive.After mold materials increased precious metal, though reach the performance requirement of heat-resistant antifriction, impact flexibility did not have the common die material good.Hot forged mould because the shaping impulsive force is big, requires mould to have certain toughness except requiring to have the heat-resistant antifriction performance simultaneously.And unitary mould is difficult to heat-resistant antifriction and impact flexibility is taken into account.

Summary of the invention

In view of the above deficiency of prior art, the utility model provides a kind of and has that heat-resistant antifriction and toughness and material cost are cheap relatively, the inserted hot forged mould of longer service life concurrently.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of hot forged mould, comprise die ontology, and the inner chamber of die ontology is provided with one and forms the embedding die of one with die ontology.Embedding die contacts with forging, and the employing alloy material different with die ontology.

The utility model compared with prior art, owing to be inserted mould, only the inner chamber that contacts with mould at forging partly adopts the very high material of hardness, then adopts the fabulous common die material of toughness in other parts of mould, so satisfied the performance requirement of heat-resistant antifriction and toughness simultaneously.And because the part that contacts with high warm forging is smaller, the special heat-resistant and wear-resistant material that adopts is few, especially special material can carry out local replacing as the case may be after wearing and tearing for a long time, therefore compare with the hot forged mould of integral body, inserted mould is function admirable not only, and saved Master Cost, and reduced manufacturing cost, significantly improved the quality and the service life of mould.

Description of drawings

Fig. 1 is a hot forging and the schematic diagram that contacts of mould.

Fig. 2 is an inserted hot forged mould structural representation of the present utility model.

Fig. 3 is an inserted hot forged mould structure upward view of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Shown in Figure 3 as Fig. 1 Fig. 2,1 is the mould part that does not contact with hot forging, and 2 is the special material mould part that contacts with hot forging, and 3 is hot forging.

At the mould part 2 that contacts with hot forging 3, can adopt the material of optimum according to its invalid characteristic with heat-resistant antifriction, and the mould part 1 that does not contact with hot forging adopts general low price mold materials, adopts built-up welding then or inlay under the suitable magnitude of interference to become one.Inlaying can be hot jacket, and cold cover or machinery are pressed into mode.

Claims

1, a kind of hot forged mould comprises die ontology, and the inner chamber that it is characterized in that die ontology is provided with one and forms the embedding die of one with die ontology.

2, hot forged mould according to claim 1 is characterized in that the part that described die ontology inner chamber contacts with forging is provided with an embedding die, and forms one with the die ontology inner chamber.
