Description
Technical Field
The invention relates to the field of machinery, in particular to a forging die for a wind power bearing ring.
Background
The die is a tool for making a blank into a finished piece with a specific shape and size under the action of external force, and is widely used for blanking, forming stamping, die forging, cold heading, extrusion, powder metallurgy piece pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. However, the wind power bearing ring is usually formed by first processing raw materials into a regular shape and then processing the raw materials into a regular shape, and the metal performance of the product is not high.
Disclosure of Invention
The invention provides a forging die for a wind power bearing ring, which aims to solve the problem that a wind power bearing ring blank moves in the die in the prior art.
In order to solve the technical problem, the invention provides a forging die for a wind power bearing ring, which comprises a main die, a core roller and a forging blank. The forging blank is arranged between the main die and the core roller, the core roller is sequentially provided with an upper sharp section, a middle section and a lower sharp section from top to bottom, the middle section is provided with a boss, and the boss is located between the upper end face and the lower end face of the forging blank.
Preferably, the boss is adjacent to an upper end face of the forging blank.
Preferably, the outer edges of the upper end face and the lower end face of the boss are provided with rounded corners.
Preferably, the middle section is of a cylindrical structure.
The invention has the following beneficial effects: according to the forging die for the wind power bearing ring, the boss is arranged in the middle section of the main die and is positioned between the upper end face and the lower end face of the forging blank, so that the inner surface of the forging is provided with the groove, the problem that the forging blank moves in the die when the ring is rolled can be effectively solved by matching the boss and the groove, and the ring rolling forming can be carried out stably. In addition, the metal flow direction at the groove of the forging is coherent, the internal performance of the product is stronger than that of a conventional rectangular reprocessed product, the product has the characteristics of tensile resistance and abrasion resistance, the material is saved by about 8%, the cost is reduced, and the energy consumption of natural gas is saved.
Drawings
Fig. 1 is an overall structure schematic of a forging die for a wind turbine bearing ring according to an embodiment of the invention. FIG. 2
The core roller of the forging die for the wind power bearing ring is shown in the embodiment of the invention.
The forging method comprises the following steps of 1-main die, 2-core roller, 201-upper sharp section, 202-middle section 203-lower sharp section, 204-lug boss and 3-forging blank.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is an overall structure schematic of a forging die for a wind power bearing ring according to an embodiment of the invention, and fig. 2 is a core roller structure schematic of the forging die for the wind power bearing ring according to the embodiment of the invention.
As shown in figures 1 and 2, the forging die for the wind power bearing ring comprises a main die 1, a core roller 2 and a forging blank 3. The forging blank 3 is arranged between the main die 1 and the core roller 2, the core roller 2 is sequentially provided with an upper sharp section 201, a middle section 202 and a lower sharp section 203 from top to bottom, the middle section 202 is provided with a boss 204, and the boss 204 is positioned between the upper end surface and the lower end surface of the forging blank 3 so as to form a groove on the inner surface of the forging.
Further, the boss 204 is adjacent to the upper end face of the forging blank 3, the outer edges of the upper end face and the lower end face of the boss 204 are provided with rounded corners, and the middle section 202 is of a cylindrical structure.
In this embodiment, the forging is wind-powered electricity generation bearing circle, and the material of wind-powered electricity generation bearing circle is multi-alloy steel, 40CrNiMO, and alloy element is more, and metal stress is bigger, and it is more difficult to the shaping. And the gear ring is used for the train, so the requirement on the internal performance of the gear ring is high, the metal streamline is coherent, and the requirements on the tensile performance and the impact performance are high. The middle section 202 is provided with a boss 204, the boss 204 is positioned between the upper end surface and the lower end surface of the forging blank 3, so that a groove is formed on the inner surface of the forging, and the boss 204 and the groove are matched to prevent the forging from moving downwards under the action of gravity.
In summary, the forging die for the wind power bearing ring provided by the invention has the advantages that the boss is arranged in the middle section of the main die and is positioned between the upper end surface and the lower end surface of the forging blank, so that the inner surface of the forging is provided with the groove, the problem that the forging blank moves in the die when the ring is rolled can be effectively solved by matching the boss and the groove, and the ring rolling forming can be carried out stably. In addition, the metal flow direction at the groove of the forging is continuous, the internal performance of the forging is stronger than that of a product which is processed and formed by a conventional rectangular die, and the forging has the characteristics of tensile strength and abrasion resistance.
The above description is only an example of the present invention, and is not intended to limit the present invention, and it is obvious to those skilled in the art that various modifications and variations can be made in the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
