Abstract
The utility model discloses a forging die for a mud pump air bag blank. The forging die for the mud pump air bag blank is characterized by being composed of an upper die body, a lower die body and a punching die body, a semispherical inner cavity is formed in the middle of the lower die body, a lower through hole is formed in the bottom of the semispherical inner cavity, a cone-frustum-shaped inner cavity is formed in the middle of the upper die body, an upper through hole is formed in the upper portion of the cone-frustum-shaped inner cavity, the upper die body is buckled to the upper portion of the lower die body, the diameter of the circumferential surface of the upper edge of the semispherical inner cavity is the same as the diameter of the circumferential surface of the lower edge of the cone-frustum-shaped inner cavity, the upper portion of the punching die body is in the shape of a cone frustum, the lower portion of the punching die body is cylindrical, and the lower portion of the punching die body is the same as the shape of an inner cavity of the mud pump air bag blank. The forging die for the mud pump air bag blank has the advantages that the forging technology is simple, the mud pump air bag blank can be formed through forging in a one-time mode, the quality of the blank is good, materials are saved, machining time is shortened, machining difficulty is lowered, and machining cost is reduced.
Description
Technical field
The utility model relates to a kind of forging mold, specifically a kind of forging mold of mud pump air bag blank.
Background technology
The forging mode of traditional mud pump air bag is that material is forged into the cylindrical shell with through hole, as shown in Figure 1, then kill hole with mould and become blank, as Fig. 2, the defect of this processing mode is: when cylindrical shell is swaged into spheroid, endoporus gauffer defect is more, remove more difficult, Forging Technology complexity, forging times used is 3 fire, increased machining period, difficulty of processing is large, has improved processing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of Forging Technology simple, and only with can forging and molding once fire, blank profiling be effective, saves material and machining period, reduction difficulty of processing, the forging mold of the mud pump air bag blank of minimizing processing cost.
In order to reach above object, the technical scheme that the utility model adopts is: the forging mold of this kind of mud pump air bag blank, it is characterized in that: it is by counterdie, patrix and punch die form, the middle part of counterdie is provided with hemispherical inner chamber, bottom at hemispherical inner chamber is provided with lower through-hole, the middle part of patrix is provided with taper type inner chamber, the top of taper type inner chamber is provided with through hole, patrix is to being buckled in the top of counterdie, the upper diameter along disc of hemispherical inner chamber is identical with the lower diameter along disc of taper type inner chamber, the top of punch die is frustum, bottom is cylindric, identical with the cavity shape of mud pump air bag blank.
The beneficial effects of the utility model are: Forging Technology is simple, and only with once fire energy forging and molding, blank quality is good, has saved material and machining period, has reduced difficulty of processing and processing cost.
