Description

Technical Field

[0001] This utility model relates to the field of forging core roller technology, specifically a forging core roller device. Background Technology

[0002] The existing Chinese patent document CN111846885B discloses a conveying device for feeding billets for ring forging production to a mandrel. The device includes a conveying track, one end of which has a receiving shell. The inner wall of the receiving shell is fixedly connected to the front and rear side walls of the conveying track. Both the front and rear side walls of the receiving shell have through holes. One of the through holes contains a baffle, and the bottom of the baffle's side wall has a square hole containing a cam. A rotating shaft is fixedly sleeved on the cam. One end of the rotating shaft passes through the side wall of the baffle and extends outward. The rotating shaft is rotatably connected to the baffle via a rotating sleeve. The upper side wall of the receiving shell has a strip-shaped hole matching the rotating shaft. This conveying device for feeding billets for ring forging production to a mandrel can conveniently and quickly convey the billet and place it onto the mandrel. It also allows two mandrels to be used alternately, facilitating billet collection.

[0003] However, in the above-mentioned schemes and existing technologies, there are still some shortcomings in the design of the outer diameter of the mandrel used for forging stepped gears. The straight cylindrical shape may cause the inner diameter machining amount of the gear to be unevenly distributed during forging. Specifically, the machining amount at the upper end of the gear is smaller, while the machining amount at the lower end is larger. This imbalance in machining amount makes the overall mass of the forging larger. Therefore, it can be optimized and improved.

[0004] Therefore, this utility model proposes a forging core roller device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a forging core roller device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a forging core roller device, comprising a base, a driving device, and a bracket, wherein the driving device is fixedly disposed on one end of the base, and the bracket is fixedly disposed on the base;

[0007] Its features include a core roller assembly, a snap-fit ​​assembly, and a fixing assembly. The core roller assembly is fixedly mounted on a bracket, the snap-fit ​​assembly is mounted at the end of the bracket, and the fixing assembly is mounted on the snap-fit ​​assembly.

[0008] Preferably, the core roller assembly has end caps fixedly provided at both ends of the core roller, large-diameter core rollers are uniformly arranged on the core roller, and a transition surface connects the large-diameter core rollers with the core rollers.

[0009] Preferably, the snap-fit ​​protrusion in the snap-fit ​​assembly is fixedly disposed at the end of the bracket, and the snap-fit ​​protrusion has an installation groove inside.

[0010] Preferably, the snap-fit ​​protrusion in the snap-fit ​​assembly is fitted with an end head, and the top of the end head is fitted with a snap-fit ​​rod.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1-2 A forging mandrel device includes a base 1, a drive device 2, and a bracket 3. The drive device 2 is fixedly installed on one end of the base 1, and the bracket 3 is fixedly installed on the base 1. The device also includes a mandrel assembly 4, a snap-fit ​​assembly 5, and a fixing assembly 6. The mandrel assembly 4 is fixedly installed on the bracket 3, the snap-fit ​​assembly 5 is installed at the end of the bracket 3, and the fixing assembly 6 is installed on the snap-fit ​​assembly 5.

[0021] The core roller assembly 4 has end caps 402 fixedly provided on both ends of the core roller 401. Large-diameter core rollers 403 are evenly arranged on the core roller 401, and a transition surface 404 connects the large-diameter core rollers 403 and the core roller 401.

[0022] When in use, the drive device 2 is activated to provide power support for the entire device. The base 1 ensures the overall stability of the device. The core roller 401 in the core roller assembly 4 starts to rotate under the drive of the drive device 2. Since the ends 402 are fixed on both sides of the core roller 401, the core roller 401 remains stable during rotation. The large-diameter core rollers 403 evenly arranged on the core roller 401, and the transition surface 404 between the large-diameter core roller 403 and the core roller 401, can guide the metal to flow evenly when forging stepped gears, effectively improving the unevenness of the gear inner diameter machining amount, making the forging process more efficient and precise, and laying the foundation for the subsequent production of high-quality forgings.

[0023] Example 2: Based on Example 1, please refer to... Figures 2-3 The snap-fit ​​protrusion 501 in the snap-fit ​​assembly 5 is fixedly installed at the end of the bracket 3, and the snap-fit ​​protrusion 501 has an installation groove 502 inside.

[0024] The snap-fit ​​protrusion 501 in the snap-fit ​​assembly 5 is adapted to snap-fit ​​end 402, and the top of end 402 is adapted to snap-fit ​​rod 503.

[0025] In use, the snap-fit ​​protrusion 501 fixed at the end of the bracket 3 plays a key role. The end 402 of the core roller assembly 4 is adapted to snap-fit ​​with the snap-fit ​​protrusion 501. This connection method is convenient and quick. When the core roller 401 rotates under the drive of the drive device 2, the snap-fit ​​protrusion 501 can stably support the end 402 and ensure the stability of the core roller 401 rotation. At the same time, the snap-fit ​​rod 503 adapted to snap-fit ​​at the top of the end 402 further enhances the firmness of the connection. In the actual forging process of stepped gears, this tight and stable connection enables the core roller assembly 4 to operate stably, ensuring the smooth progress of the forging process and improving the quality of forgings and production efficiency.

[0026] Example 3: Based on Example 2, please refer to... Figures 3-4 The mounting groove 502 in the snap-fit ​​assembly 5 is provided with a mounting hole 504 at its end. The mounting hole 504 and the fixing hole 505 are fixedly connected by a fixing pin 506. The fixing hole 505 is provided on the snap-fit ​​rod 503.

[0027] The sliding protrusions 601 in the fixing component 6 are evenly distributed on the snap-fit ​​protrusions 501. The snap-fit ​​protrusions 501 are adapted to snap-fit ​​on the snap-fit ​​grooves 602. The snap-fit ​​grooves 602 are provided on the fixing cover 603.

[0028] In use, the mounting hole 504 at the end of the mounting groove 502 is precisely aligned with the fixing hole 505 on the snap-fit ​​rod 503, and then the fixing pin 506 is used to tightly fix it, so that all parts of the snap-fit ​​assembly 5 are tightly connected. The sliding protrusion 601 in the fixing assembly 6 is evenly surrounded around the snap-fit ​​protrusion 501. The snap-fit ​​protrusion 501 and the corresponding snap-fit ​​groove 602 on the fixing cover 603 are tightly fitted and snapped together, ensuring that the core roller assembly 4 works smoothly and continuously. When the core roller assembly 4 needs to be replaced, the operator only needs to easily pull out the fixing pin 506 and slide the fixing cover 603 along a specific trajectory to quickly disassemble the core roller assembly 4 and replace it with a component suitable for the new task. The whole operation is simple and smooth, which greatly improves the maintenance efficiency of the equipment and the continuity of production, and provides strong support for the flexible adjustment of the enterprise's production rhythm.
