Description

Technical Field

[0001] This utility model relates to the field of tapered roller bearing cage processing technology, specifically a tapered roller bearing cage closing device. Background Technology

[0002] The cage of a tapered roller bearing is an important component of the bearing. It is a bearing part that partially encloses all or part of the tapered rollers and moves with them. The cage isolates the tapered rollers, typically guides them, and holds them within the bearing, maintaining an appropriate distance between them to prevent contact and reduce friction and heat generation. It distributes the tapered rollers evenly across the circumference of the raceway, ensuring the load is evenly distributed across the rolling elements, preventing bearing damage caused by load concentration. It guides the tapered rollers in the unloaded areas of the bearing, allowing them to roll smoothly on the correct raceway, improving rolling conditions and preventing harmful slippage. In separable tapered roller bearings, the cage combines the rolling elements with a raceway, preventing the rolling elements from falling out and facilitating bearing installation and removal. Tapered roller bearing cages are widely used in various mechanical devices that need to withstand combined radial and axial loads, such as wheel hub bearings and differential bearings in automobiles, spindle bearings in machine tools, rotor bearings in motors, and bearing components in various drive shafts and speed reducers.

[0003] Currently, when tapered roller bearing cages are processed by die stamping, traditional mechanical stamping relies on rigid dies, concentrating pressure on a single point. This can easily cause localized plastic deformation or fracture of the cage, especially for thin-walled copper cages, affecting the production quality of tapered roller bearing cages.

[0004] Therefore, a tapered roller bearing cage closing device is proposed to solve the above problems. Utility Model Content

Technical problem to be solved by the utility model To address the shortcomings of existing technologies, the purpose of this utility model is to provide a tapered roller bearing cage closing device. This device aims to solve the problem that, under existing technologies, traditional mechanical stamping relies on rigid dies during the closing stamping process of tapered roller bearing cages. The pressure is concentrated at a single point, which can easily cause local plastic deformation or fracture of the cage, especially for thin-walled copper cages, thus affecting the production quality of tapered roller bearing cages.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figure 1-3This embodiment provides a tapered roller bearing cage closing device, including a base 1. A feeding cylinder 14 for feeding material for the closing stamping process is installed on the top of the base 1. A support plate 2 is installed at one top end of the base 1. A stamping rod 21 is installed on the support plate 2. A sleeve 3 capable of moving up and down is installed on the stamping rod 21. Multiple closing die plates 35, capable of simultaneously stamping the tapered roller bearing cage closing process, are installed at equal intervals on the bottom outer side of the sleeve 3. When in use, the tapered roller bearing cage is placed... The material is positioned inside the feeding cylinder 14. Then, the sleeve 3 moves downward to insert multiple ferrule mold plates 35 into the inner side of the tapered roller bearing cage and fit them together. At this time, the downward punching force of the punching rod 21 enables the multiple ferrule mold plates 35 to punch against the inner wall of the tapered roller bearing cage at the same time, thereby quickly completing all the ferrule punching operations of the tapered roller bearing cage. The punching force for each ferrule is uniform, avoiding pressure concentration at a single point, thereby avoiding local plasticization or breakage of the tapered roller bearing cage, and improving the production efficiency and quality of the cage.

[0018] In this embodiment, as Figure 1 and Figure 2 As shown, the top of the limiting cylinder 13 has a groove. The cavity formed between the inner side of the feeding cylinder 14 and the top groove of the limiting cylinder 13 matches the size of the tapered roller bearing cage. The annular groove formed between the inner side of the feeding cylinder 14 and the top of the limiting cylinder 13 communicates with the discharge hole 12. Therefore, when the tapered roller bearing cage is punched, the punching fragments will enter the discharge hole 12 through the annular groove and finally fall into the inner side of the collection drawer 11 for collection, realizing the automatic centralized collection of waste materials.

[0019] In this embodiment, as Figure 1 and Figure 3 As shown, the stamping rod 21 is installed on the top inner side of the support plate 2, and the sleeve 3 is slidably sleeved on the outer ring surface of the stamping rod 21. Three electric push rods 31 are installed at equal intervals on the top outer ring surface of the sleeve 3. The top of each electric push rod 31 is fixedly connected to the bottom inner side of the support plate 2. When the electric push rod 31 starts to extend and retract, it can drive the sleeve 3 to slide up and down on the stamping rod 21.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the bottom of the sleeve 3 is conical, and multiple positioning cylinders 32 are evenly spaced on the inner side of the bottom of the sleeve 3. A telescopic rod 33 is slidably connected to the inner side of each positioning cylinder 32. A limit plate is installed at one end of the telescopic rod 33, and a spring 34 is connected between one end of the positioning cylinder 32 and the limit plate. The spring 34 is sleeved on the outer ring surface of the telescopic rod 33. The other end of each telescopic rod 33 extends outside the sleeve 3. A ferrule mold plate 35 is connected to one end of each telescopic rod 33. When the bottom of the die plate 35 extends into the feed cylinder 14, it fits against the punching position of the tapered roller bearing cage. The punching head of the punching rod 21 is located inside the sleeve 3, and the bottom of the punching head of the punching rod 21 is semi-circular. When the punching rod 21 punches downward, it will instantly squeeze all the telescopic rods 33 to slide outward. Therefore, when the punching rod 21 is started, it can simultaneously drive all the die plates 35 to punch the tapered roller bearing cage at the same time, so as to achieve synchronous punching of the opening.

[0021] Working Principle: When using this tapered roller bearing cage closing device, the tapered roller bearing cage is first placed into the loading cylinder 14 for positioning. Then, the electric actuator 31 is activated, causing the sleeve 3 to slide downwards on the stamping rod 21. This allows all the closing die plates 35 to extend into the loading cylinder 14, aligning with the closing stamping position of the tapered roller bearing cage. At this point, the stamping rod 21 is activated, simultaneously pressing all the telescopic rods 33 outwards through the semi-circular stamping head. This simultaneously drives all the closing die plates 35 to stamp the tapered roller bearing cage, quickly completing all the closing stamping operations. The stamping pressure for each closing is uniform, avoiding pressure concentration at a single point, thus preventing localized plasticization or breakage of the tapered roller bearing cage and improving the production efficiency and quality of the cage.

[0022] All technical features in this embodiment can be freely combined according to actual needs.

[0023] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
