Abstract
The utility model discloses an anti-cone roller for producing bearing rings. The anti-cone roller includes a roller head (1), and a roller body (2) which is fixedly connected to the roller head (2), and is characterized in that the roller body (2) is conical in shape. The bearing rings, produced by the roller provided in the utility model, have good quality and high qualified rate.
Description
Technical field
The utility model relates to a kind of roll that race ring is used of producing.
Background technology
Bearing is a kind of common used in industry part.Bearing commonly used comprises two concentric race rings and the roller between two race rings.Bearing enclose all is by, extrusion molding thick to round steel blanking, pier in process of production, cuts the end and become the thick embryo of tubulose, thicker embryo is rolled over expansion, produces race ring through above multiple working procedure.Rolling on the expansion technology is to adopt roll that the thick embryo of tubulose is rolled over expansion.The roll that known production race ring is used comprises roller head and the cylindrical roll body that is connected mutually with the roller head, and the roller head is actively connected on the body of roll by bearing.The thick embryo of tubulose is sleeved on the body of roll, pricks the thick embryo of calendering roller spreading tubulose of roller, reaches to make the thick embryo of tubulose roll over the purpose that expands.The shortcoming of above-mentioned roll is that calendering roller can produce extruding force when big to the body of roll when spreading, and the body of roll is produced to a lateral bending song, and the tube wall of the race ring that expands of rolling is tapered like this, influence the quality of product, so the qualification rate of product is low.
The utility model content
The purpose of this utility model is exactly to solve the roll that existing production race ring uses to roll over the race ring that expands, and produces deformation because of the body of roll when spreading power is big, makes the low problem of product percent of pass.
The technical solution adopted in the utility model is: a kind of anti-inner cone is produced the roll that race ring is used, and it comprises that the roller head reaches the body of roll that is connected mutually with the roller head, it is characterized in that the described body of roll is conical.
Adopt technique scheme, when the roll milling wheel extruding body of roll, the body of roll produces crooked, and tapered roller is in BENDING PROCESS, and cone element will be parallel with center line, offset the crooked influence that produces, thereby reach the purpose of improving the quality of products.
Above-mentioned body of roll angle of taper is 3 to 5 degree.
In sum, the beneficial effects of the utility model are: because the utility model adopts the body of roll is taper, offsets the crooked influence that produces during extruding, so the quality of the product produced of the utility model is largely increased, and the qualification rate of product also is improved.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1, the roller head, 2, the body of roll, 3, roll milling wheel, 4, race ring.
The specific embodiment
A kind of anti-inner cone of the utility model is produced the roll that race ring is used, and as shown in Figure 1, it comprises the roller head 1 and the body of roll 2 that is connected mutually with roller head 1, and it is conical that the described body of roll 2 is.The body of roll 2 angle of taper are 3 to 5 degree.Like this when roll milling wheel 3 spreading race rings 4, the crooked crooked influence that produces of the body of roll of offsetting that faces down of the epicone of the body of roll 2.
Claims (2)
1. an anti-inner cone is produced the roll that race ring is used, and it comprises that roller head (1) reaches the body of roll (2) that is connected mutually with roller head (1), it is characterized in that the described body of roll (2) is conical.
2. roll according to claim 1 is characterized in that the described body of roll (2) angle of taper is 3 to 5 degree.
