Description

Technical Field

[0001] This invention relates to the field of forging tooling technology, and in particular to a forging tooling for tapered roller bearing rings. Background Technology

[0002] Bearing rings are ring-shaped parts of radial rolling bearings with one or more raceways. However, the manufacturing of most bearing rings is currently quite complicated, inefficient, and inconvenient to use. In addition, most bearing ring manufacturing involves grinding and other processes after forging or casting, which is not only time-consuming but also labor-intensive. Therefore, the demand for a composite forging mold for tapered roller bearing rings is growing.

[0003] The manufacturing process of bearing rings requires at least four workers to work together in forging, which directly leads to a complex process and a waste of human resources. Therefore, an auxiliary forging fixture is needed to reduce the manpower required in the manufacturing process and optimize the bearing ring manufacturing process. Existing bearing ring forging composite dies lack self-cooling capabilities, causing the dies themselves to easily generate high temperatures after forging. Over time, this directly affects the service life of the dies and inevitably leads to some property damage. Summary of the Invention

The other end of the first connecting beam 122 is fixed to the movable end of the electric telescopic rod 124.

[0056] Preferably, the size of the opening cone 142 is smaller than that of the wide-hole cone 132, and during the forging process, the opening cone 142 preferentially performs the opening operation on the cast iron;

[0057] Preferably, the bottom surfaces of the collar 121, the perforated cone 142, and the wide-hole cone 132 are on the same horizontal plane.

[0059] A limiting strip 115 is installed on the inner wall of the movable sleeve 114, and the limiting strip 115 is slidably placed in the limiting groove 117 on the outer wall of the rotating column 116.

[0060] Preferably, the movable sleeve 114 can only move up and down under the restriction of the limiting strip 115 and cannot rotate independently. The movable sleeve 114 can rotate with the rotating column 116.

[0061] The bottom surfaces of the first connecting beam 122, the second connecting beam 131, and the third connecting beam 141 are all equipped with reinforcing ribs 17. The reinforcing ribs 17 at the lower ends of the second connecting beam 131 and the third connecting beam 141 are fixed to the outer wall of the movable sleeve 114.

[0063] In use, the cast iron is placed at the placement opening 32 by a manual clamp. After the initial forging is completed, the collar 121 is rotated to the placement opening 32 by rotating the telescopic bracket 11. The electric telescopic rod 124 moves downward to put the collar 121 onto the cast iron, and the stamping mechanism 6 performs stamping. The collar 121 is raised, and then the manual controls the demolding base 35 to be set up outside the placement opening 32 by the identification trigger mechanism 16. The collar 121 is lowered so that it is placed on the upper surface of the demolding base 35. Then, the manual assists in demolding with the demolding auxiliary tool. After that, the hole-opening cone 142 is placed at the placement opening 32. Under the stamping of the stamping mechanism 6, a hole is first opened in the cast iron. Then, the manual uses a clamp to turn the cast iron over and performs the hole-opening cone 142 to perform the hole-drilling operation again. Finally, the hole-expanding cone 132 is placed at the placement opening 32 to perform the hole-drilling operation. The main purpose is to expand the hole and finally complete the initial forging of the bearing collar.

[0064] In summary, the device utilizes the main and auxiliary tooling mechanism 1 to load the necessary auxiliary devices required in the bearing ring forging process. At the same time, the number of operators can be reduced to one during the forging process, without significantly reducing the forging speed and efficiency of the bearing rings. Without changing the conventional bearing ring forging process, the forging process of the bearing rings is greatly optimized. In addition, the auxiliary tooling used in the forging process is cooled during the forging process, which improves the service life of the mold. Example

[0065] Reference Figure 1 , Figure 2 and Figure 5 This is the second embodiment of the present invention;

[0066] An auxiliary alignment device 15 is also provided on the outer side of the rotating telescopic bracket 11, and the auxiliary alignment device 15 is fixed on the outer side of the rotating telescopic bracket 11.

[0067] The auxiliary alignment device 15 includes an electric take-up drum 151, which is installed on the outside of the rotating base 111. An electric take-up roller is installed inside the electric take-up drum 151. One end of the electric take-up roller is connected to the pull rope 152, and the other end of the pull rope 152 is connected to the connector 153. The connector 153 is installed on the outside of the movable sleeve 114.

[0068] When the opening cone 142 and the wide-hole cone 132 are placed at the placement opening 32, the operator can observe whether there is a gap between the bottom surface of the opening cone 142 and the wide-hole cone 132 and the upper end surface of the cast iron. If there is a gap, the movable sleeve 114 is pulled down by the pull rope 152 so that the bottom surface of the opening cone 142 and the wide-hole cone 132 contacts the upper end surface of the cast iron.

[0069] It should be noted that the pull rope 152 has a certain strength and is capable of deformation and recovery. In practical applications, the pull rope 152 can be replaced.

[0070] In summary, the main function of the auxiliary alignment device 15 is to assist the punching mechanism in performing punching operations while reducing errors.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
