Abstract
The utility model provides a chambering mold for a bearing ring forge piece. The chambering mold comprises a machine table, a motor, a chambering wheel and a chambering core. Lateral sides of the chambering wheel are indented inwards to form a circle of chambering wheel groove, the middle section of the bottom of the chambering wheel groove is a horizontal plane, and the horizontal plane extends towards the two sides to form two arc faces. The chambering core is provided with a circle of protrusions, the chambering wheel is connected with the motor, the motor is embedded into the machine table, the chambering core is arranged on the machine table below the chambering wheel, and the chambering wheel groove corresponds to the protrusions on the chambering core. The chambering mold can save a large amount of raw materials, reduces production cost and improves production efficiency.
Description
[technical field]
The utility model relates to a kind of bearing ring forging hole expansion die.
[background technology]
Staving press is a kind of swaging equipment, operation principle is: the annular blank forging is enclosed within on the milling roller, the rolling wheel of driven by motor rotation drives blank forged piece under the effect of frictional force and milling roller rotates together, under the effect of cylinder pressure, place the mould of rotation rolling the annular blank forging, make blank forging wall thickness reduction, the inside and outside circle diameter of ring increases, and makes the forging finished product through rolling.
Existing bearing ring blank forging generally forms the forging finished product of a straight barrel type after staving press processing, and then through further processing, become outer surface to the sphere of bending two ends the forging finished product processing cart of straight barrel type, inner surface has the forging finished product of a circle raceway groove; Therefore there is following shortcoming in prior art: 1, the part fallen of straight barrel type forging finished car can not recycle, and causes raw material to waste in a large number, and production cost increases; 2, operation is many, length consuming time, and production efficiency is low.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of bearing ring forging hole expansion die, can save a large amount of raw material, reduces production costs, and enhances productivity.
The utility model is achieved in that
A kind of bearing ring forging hole expansion die, described hole expansion die comprises a board, a motor, reaming wheel and a reaming core, described reaming wheel side caves inward and forms a circle reaming race, described reaming wheel trench bottom stage casing is a horizontal plane, and described horizontal plane extends to form two arcwall faces to both sides; Described reaming core is provided with a circle projection, and described reaming wheel links to each other with motor, and described motor embeds in the board, and described reaming core is arranged on the described board below the reaming wheel, and the corresponding setting of projection on described reaming race and the described reaming core.
Further, described projection is an arc-shaped protrusions.
The utility model has the advantage of:
Described reaming wheel side caves inward and forms the described reaming wheel of circle reaming race trench bottom stage casing is a horizontal plane, described horizontal plane extends to form two arcwall faces to both sides, bearing ring forging outer surface rolls through the reaming race, forms a cambered surface to bending two ends; Described reaming core is provided with a circle arc-shaped protrusions, and bearing ring forging inner surface rolls through arc-shaped protrusions, forms a circle raceway groove; Therefore the bearing ring forging is through just forming the finished product of a standard after the reaming of the present utility model, and only operation has just been finished the workload of two operations, has namely saved a large amount of raw material, has reduced production cost, has improved again production efficiency.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is reaming wheel partial side TV structure schematic diagram of the present utility model.
Fig. 2 is reaming cored structure schematic diagram of the present utility model.
Fig. 3 is structural representation of the present utility model.
[specific embodiment]
See also Fig. 1, Fig. 2 and shown in Figure 3, embodiment of the present utility model is described in detail.
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of bearing ring forging hole expansion die that the utility model is related, described hole expansion die comprises a board 1, a motor (not shown), reaming wheel 2 and one reaming core 3, described reaming is taken turns 2 sides and is caved inward and form a circle reaming race 21, stage casing, described reaming race 21 bottom is a horizontal plane 211, described horizontal plane 211 extends to form two arcwall faces 212 to both sides, bearing ring forging (not shown) outer surface rolls through reaming race 21, forms a cambered surface to bending two ends; Described reaming core 3 is provided with prominent 31 an of circle, described reaming wheel 2 links to each other with motor, described motor embeds in the board 1, and described reaming core 3 is arranged on reaming and takes turns on the described board 1 of 2 belows, and the projection 31 corresponding settings on described reaming race 21 and the described reaming core 3; Described projection 31 is an arc-shaped protrusions.
Described reaming core 3 is provided with a circle arc-shaped protrusions 31, and bearing ring forging inner surface rolls through arc-shaped protrusions 31, forms a circle raceway groove.
Therefore the bearing ring forging is through just forming the finished product of a standard after the reaming of the present utility model, and only operation has just been finished the workload of two operations, has namely saved a large amount of raw material, has reduced production cost, has improved again production efficiency
Although more than described the specific embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
