Description

Technical Field

[0001] This utility model relates to the technical field of liquid metal forging production, specifically to a refining agent addition device for liquid forging of bearing rings. Background Technology

[0002] Refining agent for liquid forging of bearing rings is a chemical preparation used in the production process of liquid forging of bearing rings to refine the molten metal. By using the refining agent, the quality of the molten metal can be effectively improved, thereby improving the quality and performance of the liquid forging of bearing rings, reducing the scrap rate, and increasing production efficiency. The refining agent addition equipment is a special device used in the process of metal smelting (such as liquid forging of bearing rings) to accurately add the refining agent to the molten metal according to the process requirements.

[0003] However, existing technologies still have the following problems:

[0004] Existing equipment mostly uses single-screw or gravity-fed conveying. For hygroscopic solid refining agents (such as those containing chloride or fluoride salts), they are prone to caking in the silo. Furthermore, single-screw conveying is prone to material accumulation due to uneven local pressure, causing pipeline blockage. Liquid refining agents, on the other hand, suffer from problems such as adhesion to pipe walls and unstable conveying volume, which seriously affect the continuity of the smelting process. In addition, traditional equipment often relies on manual control of the feeding amount or uses simple motor speed regulation, which cannot accurately match the refining agent addition ratio according to the weight of the molten metal to achieve quantitative control. Utility Model Content

[0005] To address the problems of refining agents easily caking and clogging in the silo and the inability to deliver refining agents in a quantitative manner, the purpose of this invention is to provide a refining agent addition device for liquid forging and melting of bearing rings.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a refining agent addition device for liquid forging of bearing rings, comprising a support platform, a bracket fixedly installed on the upper surface of the support platform, a conveying device fixedly installed inside the bracket, a hopper fixedly connected to the upper end of the conveying device, a second stirring paddle and a first stirring paddle rotatably connected inside the hopper, one end of the second stirring paddle and the first stirring paddle both penetrating the hopper and fixedly connected to a synchronous pulley, a synchronous belt being sleeved on the outer surfaces of the two synchronous pulleys, a servo motor fixedly installed on one side of the upper surface of the bracket, and the output end of the servo motor being fixedly connected to one end of one of the synchronous belts.

[0007] Preferably, the conveying device includes a housing, the outer surface of which is fixedly connected to a support, two screws are symmetrically rotatably connected inside the housing, a transmission box is fixedly connected to one end of the housing, one end of each of the two screws passes through the transmission box and is fixedly sleeved with a driven gear, a driving gear is rotatably connected inside the transmission box, and a reduction motor is fixedly installed on the upper surface of one side of the support platform, the output end of the reduction motor is fixedly connected to one end of the driving gear.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] This invention utilizes a combination of a hopper, a mixing paddle, and a conveying device. The hopper contains a second and a first mixing paddle, with a series of rotating mixing rods distributed around its outer surface. These rotating rods break up agglomerates of solid refining agent through centrifugal and shear forces. Combined with the gravity assistance of a conical support platform, the material converges towards the central discharge port, creating convective mixing and preventing localized agglomeration. The conveying device employs a twin-screw symmetrical rotating structure. Through the meshing of the driving and driven gears, a stable reduction ratio is achieved, ensuring a constant feed rate per screw rotation. Quantitative conveying is achieved by adjusting the screw speed using a geared motor. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Figure 1-3 As shown, this utility model provides a refining agent addition device for liquid forging of bearing rings, including a conical support platform 11. A bracket 12 is fixedly installed on the upper surface of the support platform 11. A conveying device 13 is fixedly installed inside the bracket 12. A hopper 14 is fixedly connected to the upper end of the conveying device 13. A second stirring paddle 19 and a first stirring paddle 20 are rotatably connected inside the hopper 14. Multiple stirring rods are distributed around the outer surface of the two paddles to disperse and mix the refining agent. One end of the second stirring paddle 19 and the first stirring paddle 20 passes through the hopper 14 and is fixedly connected to a synchronous pulley 21. The two synchronous pulleys 21 are driven by a synchronous belt 22. A servo motor 24 is installed on the bracket 12 to drive the synchronous belt 22. A tensioning wheel 23 is provided on one side of the hopper 14 to abut against the synchronous belt 22 to prevent slippage and ensure transmission accuracy. A feeding port 15 is opened on the upper surface of the hopper 14, and a screen 16 is fixed on the inner wall to filter large particle impurities.

[0017] The conveying device 13 includes a housing 25, the outer surface of which is fixed to the support 12. Two screws 26 are symmetrically rotatably connected inside. A transmission box 28 is fixed to one end of the housing 25. The ends of the two screws 26 pass through the transmission box 28 and are sleeved with driven gears 29. A driving gear 30 with a diameter larger than that of the driven gear 29 is rotatably connected inside the transmission box 28. A reduction motor 31 is installed on the support platform 11 to drive the driving gear 30. Through gear meshing, speed reduction and torque increase are formed to ensure that the screws 26 stably push the refining agent.

[0018] The upper surface of the shell 25 has a feed inlet 27 that is connected to the bottom discharge port of the hopper 14, so that the mixed refining agent enters the conveying device 13 under the action of gravity. The lower surface of the end of the shell 25 has a discharge port 32 that is connected to the small hopper 17 and the equal diameter tee 18 in sequence. One end of the equal diameter tee 18 is connected to the conveying hose, and the other end is connected to the output end of the air compressor. The refining agent is mixed with the compressed air here to form a gas-solid flow, which is injected into the smelting furnace through the hose to achieve residue-free blowing.

[0019] The conical structure of the support platform 11 utilizes gravity to assist material flow and reduce sedimentation; the stirring rods on the outer surface of the two stirring paddles can form a convective mixing effect when rotating at high speed, ensuring uniform composition of the refining agent. The entire equipment achieves precise addition and efficient delivery of the refining agent through modular design of filtration by screen 16, conveying by twin screws 26, and gas-solid mixing and blowing.

[0020] Working principle: The operator pours solid or liquid refining agent into the feed port 15 at the top of the silo 14. The refining agent first undergoes preliminary filtration through the screen 16 to remove impurities or agglomerated materials with particle sizes exceeding the set value, preventing them from clogging the subsequent conveying channel or affecting the mixing effect. After the servo motor 24 is started, it drives the second stirring paddle 19 and the first stirring paddle 20 to rotate at high speed in the silo 14 through the transmission system composed of the synchronous belt 22 and the synchronous pulley 21. The stirring rods on the outer surface of the stirring paddles disperse and mix the refining agent to ensure that its components are evenly distributed and to prevent agglomeration. Afterwards, the refining agent enters the conveying device 13 from the discharge port.

[0021] In the conveying device 13, the geared motor 31 drives the drive gear 30 to rotate. The drive gear 30 meshes with the driven gear 29, driving the two screws 26 to rotate synchronously. By controlling and adjusting the output frequency of the geared motor 31, the rotation speed of the screws 26 is changed, thereby achieving precise control of the conveying volume.

[0022] The refining agent is pushed to the discharge port 32 by the screw 26 and falls into the small hopper 17. Then it is combined with the compressed air flow output by the air compressor through the equal diameter tee 18. The gas-solid mixture is injected into the smelting furnace through the conveying hose (not marked in the figure).

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
