Description

Technical Field

[0001] This utility model belongs to the technical field of lithium-ion battery negative electrode material preparation equipment, specifically a lifting structure for quick replacement of tire molds. Background Technology

[0002] In the preparation of lithium-ion battery anode materials, graphitization is one of the key processes. It mainly involves heating the anode material in a high-temperature furnace to increase the degree of graphitization, thereby improving the electrochemical performance of the lithium-ion battery. The furnace core plate, as the core component that supports the anode material in the high-temperature furnace, directly affects the graphitization effect and production efficiency.

[0003] In current technologies, traditional mold replacement methods involve friction between the mold base plate and the equipment base plate. When the mold is heavy, pushing it in is difficult and time-consuming, easily scratching the base plate. Therefore, to address these issues, a lifting structure for rapid mold replacement is proposed. Utility Model Content

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Please see Figures 1-3This utility model provides a lifting structure for quick mold replacement, including a mold support base plate 4 and a base plate 6. Several heavy-duty universal balls 1 are fixedly connected to the upper end of the mold support base plate 4, and a top extension cylinder 5 is fixedly connected to the bottom end of the mold support base plate 4. An oil-free bushing 2 is sleeved on the upper end of the mold support base plate 4, and an installation workpiece 3 is fixedly connected to the upper end of the oil-free bushing 2. During operation, the top extension cylinder 5 drives the mold support base plate 4 to move up and down, thereby synchronously raising and lowering the heavy-duty universal balls 1, the oil-free bushing 2, and the installation workpiece 3 on the mold support base plate 4. The heavy-duty universal balls 1 reduce friction between the mold and the mold support base plate 4, facilitating mold movement and adjustment on the mold support base plate 4. The oil-free bushing 2 guides and lubricates the relative movement between the mold support base plate 4 and the installation workpiece 3, preventing direct contact and wear. The installation workpiece 3 is used to stably fix the oil-free bushing 2, ensuring the overall structural connection stability.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, the top of the equipment base plate 6 has several mounting holes, and the oil-free bushing 2 is attached to the bottom of the equipment base plate 6 below the mounting holes. During operation, the mounting holes provide an accurate positioning position for the oil-free bushing 2, ensuring that the oil-free bushing 2 can be accurately installed on the equipment base plate 6. The installation method of attaching from the bottom of the equipment base plate 6 allows for a tighter fit between the oil-free bushing 2 and the equipment base plate 6, reducing the gap between them, improving the stability of the oil-free bushing 2 during operation, and preventing the overall structural accuracy from being affected by installation position deviation.

[0024] Furthermore, such as Figure 1 As shown, the oil-free bushing 2 is fixedly connected to the equipment base plate 6 by the mounting workpiece 3. During operation, the mounting workpiece 3 firmly fixes the oil-free bushing 2 to the equipment base plate 6, preventing the oil-free bushing 2 from loosening or falling off during operation. This fixing method is not only reliable, but also facilitates the subsequent disassembly and replacement of the oil-free bushing 2, reducing maintenance costs and difficulty, and ensuring the long-term stable operation of the overall lifting structure.

[0025] Furthermore, such as Figure 2As shown, the ball of the heavy-duty universal ball 1 is made of bearing steel, and the outer shell is made of 45# steel plate. During operation, the ball of the heavy-duty universal ball 1 is made of bearing steel. After quenching and tempering, this steel achieves a Rockwell hardness of HRC60-65. Its microstructure consists of uniform and fine tempered martensite, combined with densely distributed carbide particles, giving it excellent resistance to plastic deformation in hardness tests. Under actual working conditions, when the mold weight reaches five tons, the surface of the bearing steel ball undergoes a 48-hour continuous friction test, with a wear of only 0.02mm. Its excellent fatigue resistance ensures that no spalling occurs under 100,000 cycles of load. The outer shell is manufactured from 45# steel plate through a stamping process. After quenching and tempering, the yield strength is increased to 355MPa, and the elongation reaches 16%, achieving a perfect balance between strength and toughness. To enhance structural stability, annular reinforcing ribs are installed on the inner side of the shell, with a thickness increased by 2mm compared to conventional designs; the outer side is hard chrome plated, achieving a surface hardness of HV800, effectively resisting external impacts such as forklift collisions. Finite element analysis verifies that when subjected to a 20kN lateral impact force, the maximum deformation of the shell is controlled within 0.3mm, maintaining precise constraint on the sphere at all times, ensuring the omnidirectional ball can move flexibly within a ±360° rotation range without jamming.

[0026] Furthermore, such as Figure 1 As shown, the oil-free bushing 2 is a mixture of copper alloy and polytetrafluoroethylene (PTFE). During operation, the copper alloy exhibits good thermal conductivity and wear resistance, while PTFE possesses excellent self-lubricating properties and chemical stability. The oil-free bushing 2, made from this mixture, combines the high strength and wear resistance of the copper alloy, enabling it to withstand the wear caused by the relative movement between the substrate 4 and the mounting workpiece 3, with the self-lubricating properties of PTFE. This eliminates the need for additional lubricating oil, achieving good lubrication and reducing frictional resistance. Furthermore, it resists corrosion from various chemicals, extending the service life of the oil-free bushing 2.

[0027] Working Principle: This lifting structure for quick mold changing firstly attaches the oil-free bushing 2 to the bottom of the equipment base plate 6 through several mounting holes at the top. Then, the mounting workpiece 3 secures the oil-free bushing 2 to the equipment base plate 6, completing the installation and fixation of the oil-free bushing 2 to the equipment base plate 6. Several heavy-duty universal balls 1, with bearing steel bodies and 45# steel shells, are fixedly connected to the upper end of the mold support base plate 4. The bottom end is fixedly connected to the top extension cylinder 5. The oil-free bushing 2 is fitted onto the upper end of the mold support base plate 4. Bearing steel has high hardness, wear resistance, and fatigue resistance, ensuring that the heavy-duty universal balls 1 maintain good performance even under long-term mold pressure and friction, and are not prone to wear or damage. 45# steel... The steel plate has good strength and toughness, providing stable support and protection for the ball of the heavy-duty universal ball 1, preventing deformation of the outer shell under external impact, and ensuring the normal rotation function of the heavy-duty universal ball 1. The oil-free bushing 2 is a mixture of copper alloy and polytetrafluoroethylene (PTFE). Copper alloy has good thermal conductivity and wear resistance, while PTFE has excellent self-lubricating properties and chemical stability. The oil-free bushing 2 made of the two has both the high strength and wear resistance of copper alloy, which can withstand the wear caused by the relative movement between the substrate 4 and the mounting workpiece 3, and the self-lubricating properties of PTFE, which can achieve good lubrication without the need for additional lubricating oil, reducing frictional resistance. At the same time, it can also resist the corrosion of various chemicals and extend the service life of the oil-free bushing 2. When mold replacement is required, the top extension cylinder 5 is activated, driving the film support plate 4 upward. The film support plate 4 drives the heavy-duty universal ball 1, the oil-free bushing 2, and the mounting workpiece 3 to rise synchronously. The heavy-duty universal ball 1 reduces the friction between the mold and the film support plate 4, allowing the operator to easily push the mold onto the film support plate 4 to the appropriate position. After adjustment, the top extension cylinder 5 drives the film support plate 4 downward, placing the mold stably in the designated position. Throughout the process, the oil-free bushing 2 guides and lubricates the lifting and lowering movement of the film support plate 4, ensuring the smoothness and accuracy of its movement. The coordinated work of all components enables rapid mold replacement, improving work efficiency. At the same time, the use of high-quality materials and reliable connection methods ensures the stability and service life of the overall structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
