Abstract
The utility model discloses a molybdenum crucible forging die. The forging die comprises an upper die and a lower die, wherein the punch of the upper die is over against the orifice of the lower die. The forging die is characterized in that the cavity of the lower die is an inverted trapezoid. The forging die has a simple structure, is convenient to use and can save raw materials and production cost.
Description
Technical field
the utility model belongs to field of machining, is specifically related to a kind of molybdenum crucible forging die.
Background technology
Duan Mo is the instrument of hot forging, and section mould impression is processed and the concavo-convex opposite respective shapes of required forging, and makes suitable somatotype.Forge piece blank reheating is heated in the forging range on the recrystallization temperature of metal, is placed on the Duan Mo, utilize the pressure of forging equipment blank forging to be become to have the forging of overlap or minimum overlap again.According to the difference of the equipment of use, forging die divides hammer forging die, mechanical press forging die, screw press forging die, upset forging die etc.Forging die is processed the metal under the condition of high temperature, and condition of work is relatively poor, need bear repeated stock load and alternating hot and cold effect, produces very high stress.Also can long-living friction effect during metal flow.Therefore mould should have high intensity, hardness, wearability, toughness, oxidative resistance, heat conductivity and hot-cracking resistance under operating condition.Molybdenum crucible adopts the FMo-1 molybdenum powder to produce, and extrudate density is greater than 9.8g/cm3, and serviceability temperature is greater than 1100 ℃.Be mainly used in industries such as metallurgical industry, rare-earth trade, monocrystalline silicon, artificial crystal.Existing molybdenum crucible production is to adopt ￠ 200 ㎜ straight hole moulds to produce semi-finished product, and then cuts, and so not only wastes raw material, and has also increased cost of labor.
Summary of the invention
the utility model purpose is: provide a kind of simple in structure, easy to use, can economize in raw materials and the molybdenum crucible forging die of production cost.
The technical scheme of
the utility model is: a kind of molybdenum crucible forging die, comprise upper die and lower die, the drift of patrix and the die orifice of counterdie over against, it is characterized in that, the die cavity of said counterdie below being little above big stairstepping.
are further, the single order of the die cavity of said notch cuttype below being little above big truncated cone-shaped.
The utility model has the advantages that:
are simple in structure, easy to use, can economize in raw materials and production cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the molybdenum crucible forging die structure chart of the utility model.
The specific embodiment
embodiment: molybdenum crucible forging die as shown in Figure 1; Comprise upper die and lower die; The drift of patrix and the die orifice of counterdie below over against, the die cavity of counterdie being little above big stairstepping, the single order of the die cavity of notch cuttype below being little above big truncated cone-shaped.Compare original employing ￠ 200 ㎜ straight hole moulds and produce semi-finished product, and then cut, the utility model can be practiced thrift half the material, even if press 280 yuan of Mo 1 ㎏, each can practice thrift 2240 yuan.
above embodiment is merely the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
Claims (2)
1. a molybdenum crucible forging die comprises upper die and lower die, the drift of patrix and the die orifice of counterdie over against, it is characterized in that, the die cavity of said counterdie below being little above big stairstepping.
