Description

Technical Field

[0001] This invention relates to the field of high-pressure forming equipment for graphene materials, and in particular to a high-pressure forming device and method for graphene high-speed steel bearings. Background Technology

[0002] Bearings are widely used in various high-speed rotating equipment, new energy battery production lines, kiln cars and high-temperature equipment, military industry, steel metallurgy, boiler fans, liquid nitrogen equipment, solar cells, nanoelectronics, sensors, cement plant equipment, dust conveying equipment for spraying, and other high and low temperature operating equipment due to their high strength and excellent wear resistance.

[0003] Currently, the domestic market mainly uses traditional bearings lubricated with high and low temperature greases or oils. Regardless of whether imported or domestic bearings are used, they suffer from high prices and short lifespans. Furthermore, repeatedly adding lubricating oil inside the bearings causes environmental pollution and impacts environmental protection. Graphene solid-state lubricated bearings use high-purity graphite as a solid lubricant, which is non-toxic and harmless to the environment, providing long-term continuous lubrication. This offers cleaning-free, maintenance-free, and environmentally friendly bearing components for equipment in various industries, significantly extending equipment lifespan.

[0004] In the traditional manufacturing process of graphene solid-state lubricated bearings, the high-pressure forming process typically relies on manual operation. This method suffers from inconsistent finished product quality and low production efficiency. Especially during graphite material placement and high-pressure forming, uneven pressure or insufficient graphite filling can easily lead to inconsistent surface hardness and internal voids in the bearing. Consequently, problems gradually emerge in subsequent bearing manufacturing processes, primarily manifesting as surface defects and cracks that expose the internal rolling elements, preventing them from undergoing further processing. This results in material waste and low production efficiency. Therefore, there is an urgent need to research high-pressure forming equipment for graphene solid-state lubricated bearings that can ensure high efficiency and consistency in manufacturing. Summary of the Invention

[0005] The purpose of this invention is to provide a graphene high-speed steel bearing high-pressure forming device and method with high automation, high production efficiency and high product quality stability.

[0006] The technical solution to achieve the purpose of this invention is: a high-pressure forming device for graphene high-speed steel bearings, comprising a human-machine interaction system, an automatic loading and unloading system, a high-pressure forming system, and a control system.

[0007] The human-computer interaction system is used to display the device's operating status and related parameters, and to perform device start-up, stop, mode switching, and parameter setting operations.

[0008] The automatic loading and unloading system is used for loading graphene high-speed steel bearings and unloading finished products.

[0009] The high-pressure forming system is used to perform high-pressure forming operations on graphene high-speed steel bearings.

[0010] The control system is used to control the synchronous operation of each component.

[0011] Furthermore, the human-machine interaction system includes a display control screen and manual control buttons. The display control screen is located at the upper end of the high-pressure forming device and is used to display the operating status and related parameters of the equipment. The manual control buttons are located at the lower end of the display control screen and are used to start, stop, switch modes, and set parameters of the equipment.

[0012] Furthermore, the automatic loading and unloading system includes a vibrating conveyor belt, a drive motor, a bearing mounting base, a proximity switch sensor, a mechanical claw truss, a first servo motor, a truss guide rail, a second servo motor, an automatic demagnetizer, a magnetic mechanical claw, and a suction claw.

[0013] The vibrating conveyor belt is located at the right end of the high-pressure forming device and is driven by a drive motor to transport the bearings. A bearing mounting seat is provided at the end of the vibrating conveyor belt, and a proximity switch sensor is provided at the lower end of the bearing mounting seat. The vibrating conveyor belt transports the high-speed steel bearings to be processed to the bearing mounting seat, and the bearings are stably arranged by vibration during the transmission process. When the proximity switch sensor detects that the bearing mounting seat is full, the vibrating conveyor belt stops transmitting to avoid the bearings piling up and affecting subsequent operations.

[0014] The mechanical claw truss is located at the upper end of the high-pressure forming device and is controlled to move by the first servo motor. The lower end of the high-pressure forming device is provided with a truss guide rail. The magnetic mechanical claw is located on the mechanical claw truss and is driven to move by the second servo motor. The magnetic mechanical claw is equipped with a positioning sensor. When the positioning sensor detects that the bearing has entered the bearing fixing seat, the magnetic mechanical claw is driven by the truss guide rail and the mechanical claw truss to send the bearing into the high-pressure forming system for high-pressure forming operation, and then removes the high-pressure formed bearing out of the high-pressure forming system.

[0015] The magnetic mechanical claw is equipped with an automatic demagnetizer at the top and a suction claw at the bottom. The automatic demagnetizer uses demagnetization technology to eliminate the magnetism of the high-speed steel bearing before the magnetic mechanical claw grips it.

[0016] Furthermore, the high-pressure forming system includes a servo press frame, a servo press, a high-pressure forming ejector pin, a mold frame, and a high-pressure forming mold. The high-pressure forming mold is equipped with a material spreading platform and a bearing pressing groove.

[0017] The high-pressure forming push rods are of two types, which perform double-sided high-pressure forming on the upper and lower end faces of the high-speed steel bearing from the top and bottom respectively; the high-pressure forming mold includes a base and a top cover, the high-speed steel bearing is placed between the base and the top cover of the high-pressure forming mold, graphite material is evenly filled to the upper and lower surfaces of the bearing, and the graphite material is ensured to be evenly filled during the high-pressure forming process.

[0018] The servo press frame is located in the middle of the high-pressure forming device. A mold frame is set below the servo press frame, and a lower high-pressure forming ejector rod is set at the center of the top of the mold frame. A servo press is set at the top of the servo press frame, and an upper high-pressure forming ejector rod is set below the servo press. A high-pressure forming mold base is set at the top of the mold frame. A bearing pressure groove is set in the center of the high-pressure forming mold base, and a material spreading platform is set on the upper surface of the base for evenly spreading graphite material in the bearing pressure groove of the base. A bearing pressure groove is set in the center of the high-pressure forming mold cover, corresponding to the bearing pressure groove of the base. A material spreading platform is set on the upper surface of the high-pressure forming mold cover for evenly spreading graphite material in the bearing pressure groove of the cover. The upper and lower high-pressure forming ejector rods correspond to the bearing pressure grooves on the high-pressure forming mold. The inner diameter of the bearing pressure groove is the same as the outer diameter of the high-pressure forming ejector rod. They are detachable devices and are arranged vertically. The upper high-pressure forming ejector rod performs the bearing high-pressure forming operation under the action of the servo press.

[0019] Furthermore, a graphite material filling device is provided above the high-pressure forming mold to lay graphite material on the base and top cover of the high-pressure forming mold respectively, and to ensure the uniform laying of graphite material through a metering and distribution mechanism.

[0020] Furthermore, the upper end of the high-pressure forming mold cover is provided with a bearing inner ring plug, which is set on the lathe surface and moved by a magnetic mechanical claw to fix the bearing inner ring during the high-pressure forming of graphite material, thereby ensuring the stability of the bearing during the forming process.

[0021] Furthermore, the high-pressure molding system has a synchronous operation safety start mechanism and is equipped with safety light curtains on both sides to ensure that there are no foreign objects inside the servo press and that both hands must be used simultaneously to perform the high-pressure molding operation.

[0022] Furthermore, the control system includes a control cabinet, a main controller, and an exhaust system;

[0023] The control cabinet is located at the bottom of the high-pressure forming device. The main controller is installed in the control cabinet, and an exhaust system is installed on the side of the control cabinet to reduce the temperature of the control cabinet and reduce dust pollution.

[0024] Furthermore, the front end of the control cabinet is equipped with a graphite material storage funnel, which is used to store the graphite material residue on the high-pressure forming device during the high-pressure forming process, thereby keeping the equipment clean.

[0025] A method for high-pressure forming of graphene high-speed steel bearings includes the following steps:

[0026] Step 1, Automatic feeding: Start the high-pressure forming device, place the high-speed steel bearing to be processed on the vibrating conveyor belt, and transfer it to the bearing mounting seat through the vibrating conveyor belt. After the proximity switch sensor at the end of the bearing mounting seat senses the high-speed steel bearing, it sends a signal to the main controller.

[0027] Step 2, Automatic Demagnetization: After receiving the sensor signal, the main controller controls the magnetic mechanical gripper to remove the high-speed steel bearing from the bearing holder. During the removal process, the automatic demagnetizer at the upper end of the magnetic mechanical gripper demagnetizes the high-speed steel bearing.

[0028] Step 3, Laying the bearings: After demagnetization, the magnetic mechanical gripper lays the high-speed steel bearings between the high-pressure forming molds;

[0029] Step 4, Double-layer material laying: Graphite material is laid on the base of the high-pressure forming mold. The magnetic mechanical claw places the high-speed steel bearing in the inner ring of the mold. After the bearing is placed, the upper cover of the high-pressure forming mold is lowered to cover the bearing. After the plug is placed in the inner ring of the upper cover of the high-pressure forming mold, the upper layer of graphite material is laid to ensure the stability of the high-pressure forming of graphite material.

[0030] Step 5, Double-sided molding: After the graphite material is laid, the high-pressure molding system is started. The high-pressure molding push rod on the upper side uses a servo press to perform double-sided molding on the upper and lower end faces of the high-speed steel bearing, ensuring that the pressure is evenly distributed on the upper and lower surfaces of the bearing.

[0031] The significant advantages of this invention compared to existing technologies are:

[0032] (1) Double-sided molding of the upper and lower end faces of the high-speed steel bearing ensures that the pressure is evenly distributed on the upper and lower surfaces of the bearing, which improves the finished product quality of the graphene high-speed steel bearing, especially in terms of bearing surface hardness and internal density.

[0033] (2) The automatic loading and unloading system and servo pressure system are adopted to realize the automation of graphene solid lubricated bearing production, improve production efficiency, reduce labor costs, and are suitable for large-scale production.

[0034] (3) The pressure during the pressing process is precisely controlled by a servo pressure system to ensure the uniform distribution of graphite material in the mold and the molding quality, thereby improving the quality consistency of the final product and reducing errors caused by human operation.

[0035] (4) The two-hand start mechanism is adopted. High pressure molding will only be performed when the start button is pressed at the same time, which improves the safety of operation and reduces potential operational risks.

[0036] (5) The precision material spreading device in the high pressure forming mold ensures the uniform spreading of graphite material. Excess material is recycled and reused through the graphite material storage funnel, reducing graphite material waste, improving material utilization, and enhancing the economic efficiency of production.

[0037] (6) The equipment is easy to maintain and environmentally friendly. The exhaust system in the control cabinet effectively reduces the temperature and dust accumulation during equipment operation, extends the service life of the equipment, keeps the working environment clean, reduces the maintenance needs of the equipment, and improves the operating environment.

[0038] (7) Through the human-computer interaction system, operators can intuitively control the operation of the equipment, set relevant parameters, and monitor the production process at any time. The operation is simple and suitable for operators of different levels.

[0039] (8) The demagnetization process is efficient and stable. The automatic demagnetizer ensures that the bearing is thoroughly demagnetized before each gripping, eliminating product defects that may be caused by magnetic residue in subsequent processes, thereby ensuring the stability and quality of graphene high-speed steel bearing products.
