Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy battery box shell extrusion, and in particular to an aluminum alloy battery box shell extrusion device and a working method thereof. Background Art

[0002] The background technology of the aluminum alloy battery box shell extrusion device mainly involves the extrusion molding process of aluminum alloy materials. With the continuous advancement of battery technology, especially in the field of new energy vehicles and energy storage systems, aluminum alloy materials have gradually become the main materials for battery box shells due to their lightweight, good thermal conductivity and strong corrosion resistance. Aluminum alloy battery box shells are usually manufactured using aluminum alloy profile extrusion molding technology. Extrusion molding technology is a process in which aluminum alloy ingots are plastically processed at high temperatures to form profiles of different cross-sections through a die mouth. This technology has the advantages of high production efficiency, high material utilization, and good processing accuracy. In the production of aluminum alloy battery box shells, the extrusion device usually needs to meet the following requirements: The battery box shell requires high dimensional accuracy and surface quality, especially in the design of the shape and inner cavity structure. The extrusion molding process of aluminum alloy has a high operating difficulty, and the stability of the equipment must be ensured to avoid product defects. Since aluminum alloy materials are easily deformed at high temperatures, the cooling system is crucial to maintaining product quality. Improper cooling can cause surface defects of aluminum alloys or deformation of finished products. With the development of manufacturing technology, more and more aluminum alloy battery box shell production lines use automated equipment to improve production efficiency and reduce the impact of human factors.

[0003] In the existing aluminum alloy extrusion forming technology, the cooling system often has a certain amount of energy waste during long-term operation. The function of the cooling system is to quickly cool the extruded aluminum alloy profile to room temperature to avoid deformation and defects, but traditional cooling methods (such as water cooling or air cooling) usually have the following problems, resulting in energy waste: In some traditional cooling systems, in order to ensure that the aluminum alloy profile can be cooled in time, the flow rate of the coolant is usually large, or the cooling fan needs to continue to operate at high power. This overcooling will lead to unnecessary energy consumption. If the temperature distribution during the cooling process is uneven or the cooling speed is not ideal, it may take longer or more energy to achieve the ideal cooling effect.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs an aluminum alloy battery box shell extrusion device and a working method thereof, which solves the above technical problems. Summary of the invention

[0005] The technical purpose to be achieved by the present invention is to design an aluminum alloy battery box shell extrusion device and a working method thereof to solve the problem of certain energy waste in the cooling system during long-term operation in the prior art.

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0007] The aluminum alloy battery box shell extrusion device of the present invention includes a base, a driving motor, a control cabinet, a feeding box, a transport pipe, a spiral feeding rod, a discharging mechanism and a molding mechanism. The driving motor is installed on the base, the control cabinet is installed on the side of the driving motor, the feeding box is installed on the side of the control cabinet, the transport pipe is installed on the side of the feeding box, the spiral feeding rod is installed inside the transport pipe, the discharging mechanism is installed on the side of the transport pipe, and the molding mechanism is installed on the side of the discharging mechanism. The spiral feeding rod feeds the material into the molding mechanism through the discharging mechanism, and the discharging mechanism realizes a control switch for replacing and circulating the cooling water in the molding mechanism once during a single molding operation.

[0008] The discharging mechanism comprises a discharging block, a control panel, a control block, a rotating shaft, a driving blade and a driving gear. The discharging block is installed on the side of the transport pipe, the control panel is installed on the top of the discharging block, the control block is installed inside the discharging block, the rotating shaft is installed in the middle of the discharging block, the driving blade is installed on the rotating shaft, and the driving gear is installed at both ends of the rotating shaft.

[0009] The discharging block includes a transition channel, an extrusion channel and an installation cavity. The transition channel is opened on the side where the discharging block and the transport pipe are installed, the extrusion channel is opened in the middle of the discharging block, and the installation cavity is opened on both sides of the extrusion channel. The cross-sectional shape of the transition channel is set to be a trapezoid, wherein the side with a larger opening area is set on the outside.

[0010] The control disk includes an extrusion pipe, an exchange pipe, a connection cavity and an exchange flow channel. The extrusion pipe is installed in the middle of the control disk, the exchange pipe is installed on the side of the control disk, the connection cavity is opened inside the control disk, the connection cavity is set in an annular shape, and the exchange flow channel is opened on the side of the control disk.

[0011] The control block comprises a reciprocating tooth, a switch block and a return spring. The reciprocating tooth is arranged on the top of the control block, the switch block is installed on one side of the control block, and the return spring is installed on the other side of the control block.

[0012] The molding mechanism comprises a fixed seat, a telescopic rod, a support spring and an inner mold assembly. The fixed seat is mounted on the base, the telescopic rod is mounted on the fixed seat, the support spring is mounted outside the telescopic rod, and the inner mold assembly is mounted inside the fixed seat.

[0013] The inner mold assembly includes an inner mold base, an inner mold core, a cooling pipe and a feed port. The inner mold base is installed inside the fixed base, the inner mold core is installed inside the inner mold base, the cooling pipe is installed outside the inner mold base, and the feed port is opened in the middle of the cooling pipe. The inner mold base is set as a hollow structure.

[0014] A working method of an aluminum alloy battery box shell extrusion device, which is applicable to the above-mentioned aluminum alloy battery box shell extrusion device; the steps of the method are as follows:

[0015] S1: The operator selects appropriate aluminum alloy raw materials according to production requirements and puts them into the feeding box of the device to ensure that the raw materials enter the feeding area accurately;

[0016] S2: The drive motor starts, driving the spiral feeding rod to transport the raw materials in the feeding box into the discharging mechanism. The control system starts the drive motor, and the motor drives the spiral feeding rod to rotate through the reduction mechanism. The spiral feeding rod adopts a variable pitch design, with a smaller pitch at the front end to ensure stable feeding, and a larger pitch at the rear end to improve the conveying efficiency. The raw materials are pushed by the spiral feeding rod and move evenly to the discharging mechanism;

[0017] S3: When the raw material enters the extrusion channel through the transition channel, it drives the driving blades to rotate, causing the driving gears installed at both ends of the rotating shaft to rotate. The meshing motion of the driving gears and the reciprocating teeth drives the control block to move backward. The connecting cavity and the exchange flow channel are connected. After the cooling water enters the connecting cavity through the exchange flow channel, it enters the cooling pipe through the exchange flow channel.

[0018] S4: After the cooling water enters the hollow inner mold base through the cooling pipe and circulates, it flows out from another cooling pipe to achieve circulating cooling; the cooling water forms turbulence inside the inner mold base to improve the heat exchange efficiency; after the cooling water absorbs the heat of the mold, the temperature rises and flows out through the auxiliary cooling pipe.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) The present invention solves the problem that in traditional cooling systems, cooling water usually flows continuously, and the cooling system will continue to run regardless of the raw material filling process or the molding process, which will lead to a large amount of energy waste. By controlling the switch of the cooling system during the raw material filling process, the cooling water flow is started only when needed (such as when entering the extrusion molding stage), and the cooling system is turned off when cooling is not needed, thereby effectively avoiding unnecessary energy consumption. This on-demand switch control greatly improves the energy utilization efficiency of the system and reduces energy waste.

[0021] (2) The flow of cooling water in the present invention is only started in key links, such as extrusion molding and cooling process, ensuring the cooling effect while not extending unnecessary time or consuming extra energy due to overcooling. The control system can adjust the flow of cooling water in real time according to production needs, avoiding excessive or uneven cooling during the cooling process, and improving the working efficiency and molding accuracy of the entire system.

[0022] (3) The present invention reduces unnecessary operation of the cooling system, which can reduce the load on the cooling water equipment and reduce wear and failure caused by long-term operation, thereby extending the service life of the cooling system and the entire device. This also reduces the maintenance cost and maintenance frequency of the equipment. By accurately controlling the switch of the cooling system, it can be ensured that the cooling water is circulated only when the raw material is extruded and needs to be cooled, avoiding additional heat loss caused by the long-term flow of cooling water. This helps to better maintain the stable temperature of the equipment and the molding material, thereby improving production quality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] like Figure 1-10 As shown, the aluminum alloy battery box shell extrusion device of the present invention includes a base 1, a drive motor 2, a control cabinet 3, a feed box 4, a transport pipe 5, a spiral feeding rod 6, a discharging mechanism 7 and a molding mechanism 8. The drive motor 2 is installed on the base 1, the control cabinet 3 is installed on the side of the drive motor 2, the feed box 4 is installed on the side of the control cabinet 3, the transport pipe 5 is installed on the side of the feed box 4, the spiral feeding rod 6 is installed inside the transport pipe 5, the discharging mechanism 7 is installed on the side of the transport pipe 5, and the molding mechanism 8 is installed on the side of the discharging mechanism 7. The spiral feeding rod 6 feeds the material into the molding mechanism 8 through the discharging mechanism 7. In a single molding operation, the discharging mechanism 7 realizes the control switch for replacing and circulating the cooling water in the molding mechanism 8 once. The base 1 serves as a supporting platform for the entire device to ensure the stable installation of each component and the stable operation of the equipment. The drive motor 2 is responsible for providing power, and is precisely controlled through the control cabinet 3 to ensure the coordinated operation of the motor and other components. The feeding box 4 works with the transport pipe 5 to accurately feed the material into the spiral feeding rod 6, which pushes the material forward by rotating to ensure the continuous supply of the material. The discharging mechanism 7 is responsible for the discharge of the material and the replacement of the cooling water during the forming process. The forming mechanism 8 is the core part that finally shapes the material into the required profile, ensuring the high-precision manufacturing of the aluminum alloy battery box shell.

[0038] like Figure 3As shown, the discharging mechanism 7 includes a discharging block 71, a control panel 72, a control block 73, a rotating shaft 74, a driving blade 75 and a driving gear 76. The discharging block 71 is installed on the side of the transport pipe 5, the control panel 72 is installed on the top of the discharging block 71, the control block 73 is installed inside the discharging block 71, the rotating shaft 74 is installed in the middle of the discharging block 71, the driving blade 75 is installed on the rotating shaft 74, and the driving gear 76 is installed at both ends of the rotating shaft 74. The discharging mechanism 7 is an important part of the aluminum alloy battery box shell extrusion device, and its function is to accurately feed the material sent out by the spiral feeding rod 6 into the forming mechanism 8 after a series of adjustments and treatments. The discharging mechanism 7 includes components such as a discharging block 71, a control panel 72, a control block 73, a rotating shaft 74, a driving blade 75 and a driving gear 76. The design of the discharging block 71 is to ensure the stable transmission of the material, and the transition channel 711 and the extrusion channel 712 inside it provide a reasonable flow path for the material. The control panel 72 and the control block 73 are arranged to precisely control the cooling water circulation, thereby preventing the influence of too high or too low temperature on the material forming. The combination of the rotating shaft 74 and the driving blade 75 can effectively adjust the conveying speed and cooling effect of the material, thereby preventing the quality problems caused by overcooling or insufficient cooling. The driving gear 76 ensures the efficient operation of the entire discharging system.

[0039] like Figure 4 As shown, the discharging block 71 includes a transition channel 711, an extrusion channel 712 and an installation cavity 713. The transition channel 711 is opened on the side where the discharging block 71 and the transport pipe 5 are installed, the extrusion channel 712 is opened in the middle of the discharging block 71, and the installation cavity 713 is opened on both sides of the extrusion channel 712. The cross-sectional shape of the transition channel 711 is set to be a trapezoid, wherein the side with a larger opening area is set on the outside. The design of the discharging block 71 is to ensure that the material can reach the molding area smoothly and efficiently from the transport pipe 5. The trapezoidal design of the transition channel 711, especially the side with a larger opening facing outward, helps to better guide the material into the extrusion channel 712, avoiding the blockage problem caused by overcrowding or poor flow of materials. The middle opening of the extrusion channel 712 can effectively concentrate the material for precise extrusion, ensuring uniformity during the molding process. The setting of the installation cavity 713 provides convenience for subsequent assembly and maintenance, making the disassembly and cleaning of the equipment more efficient and quick.

[0040] like Figure 5As shown, the control disk 72 includes an extrusion pipe 721, an exchange pipe 722, a connecting cavity 723 and an exchange flow channel 724. The extrusion pipe 721 is installed in the middle of the control disk 72, the exchange pipe 722 is installed on the side of the control disk 72, the connecting cavity 723 is opened inside the control disk 72, the connecting cavity 723 is set in an annular shape, and the exchange flow channel 724 is opened on the side of the control disk 72. The design of the control disk 72 is to effectively regulate the flow and exchange of cooling water to ensure the accuracy of temperature control during the molding process. The setting of the extrusion pipe 721 and the exchange pipe 722 allows the material to have a good heat exchange with the cooling water during the extrusion process to maintain the best cooling effect. The annular structure of the connecting cavity 723 can ensure the uniform flow of cooling water, and the design of the exchange flow channel 724 helps to make real-time adjustments during the flow of cooling water, optimize the overall cooling effect, prevent local overheating or insufficient cooling, and thus ensure the accuracy and consistency of each molding process.

[0041] like Figure 6 As shown, the control block 73 includes a reciprocating tooth 731, a switch block 732 and a reset spring 733. The reciprocating tooth 731 is arranged on the top of the control block 73, the switch block 732 is installed on the side of the control block 73, and the reset spring 733 is installed on the other side of the control block 73. The control block 73 is designed to accurately control the flow and replacement of cooling water. The function of the reciprocating tooth 731 is to cooperate with other components to achieve precise regulation of the cooling water flow; the switch block 732 is installed on the side of the control block 73 to open and close the fluid channel, thereby realizing the switch control of the cooling system and ensuring the controllability of the cooling effect. The reset spring 733 can reset the switch block 732 after each operation to ensure the normal operation of the system at different stages and avoid misoperation or equipment jamming.

[0042] like Fig. 9 As shown, the forming mechanism 8 includes a fixed seat 81, a telescopic rod 82, a support spring 83 and an inner mold assembly 84. The fixed seat 81 is installed on the base 1, the telescopic rod 82 is installed on the fixed seat 81, the support spring 83 is installed on the outside of the telescopic rod 82, and the inner mold assembly 84 is installed inside the fixed seat 81. The forming mechanism 8 is a key link in the production process of the aluminum alloy battery box shell, which determines the shape and quality of the final product. The fixed seat 81 provides a stable support platform to ensure the precise positioning of the inner mold assembly 84. The setting of the telescopic rod 82 and the support spring 83 can adjust the position of the inner mold assembly 84 according to production requirements, so as to adapt to the molding requirements of battery box shells of different sizes and shapes. Through this flexible and adjustable design, it can better adapt to the production of products of different types and batches, and improve the versatility and production efficiency of the equipment.

[0043] like Fig.10As shown, the inner mold assembly 84 includes an inner mold base 841, an inner mold core 842, a cooling pipe 843 and a feed port 844. The inner mold base 841 is installed inside the fixed base 81, the inner mold core 842 is installed inside the inner mold base 841, the cooling pipe 843 is installed outside the inner mold base 841, and the feed port 844 is opened in the middle of the cooling pipe 843. The inner mold base 841 is set as a hollow structure. The inner mold assembly 84 is the part of the forming mechanism 8 that directly contacts the aluminum alloy material and is responsible for accurately shaping the material into the required profile. The inner mold base 841 provides a stable support for the inner mold core 842, and its hollow structure design helps to improve the heat dissipation performance of the mold, thereby improving the forming quality of the aluminum alloy profile. The inner mold core 842 ensures that the size and shape of the aluminum alloy profile meet the requirements through precise design. The setting of the cooling pipe 843 provides the necessary cooling channel for the material, avoiding the forming defects caused by uneven cooling. The feed port 844 is designed in the middle of the cooling pipe 843, so that the cooling water can flow better through the entire forming area, ensuring uniform cooling and high-quality forming of the aluminum alloy profile.

[0044] A working method of an aluminum alloy battery box shell extrusion device, which is applicable to the above-mentioned aluminum alloy battery box shell extrusion device; the steps of the method are as follows:

[0045] S1: The operator selects appropriate aluminum alloy raw materials according to production requirements and puts them into the feeding box 4 of the device to ensure that the raw materials accurately enter the feeding area;

[0046] S2: The driving motor 2 is started, driving the spiral feeding rod 6 to transport the raw materials in the feeding box 4 into the discharging mechanism 7. The control system starts the driving motor 2, and the motor drives the spiral feeding rod 6 to rotate through the reduction mechanism. The spiral feeding rod 6 adopts a variable pitch design, with a smaller pitch at the front end to ensure stable feeding, and a larger pitch at the rear end to improve the conveying efficiency. The raw materials are pushed by the spiral feeding rod 6 and move evenly to the discharging mechanism 7;

[0047] S3: When the raw material enters the extrusion channel 712 through the transition channel 711, the driving blade 75 is driven to rotate, so that the driving gears 76 installed at both ends of the rotating shaft rotate, and the driving gear 76 and the reciprocating gear 731 mesh and drive the control block 73 to move backward, and the connecting chamber 723 and the exchange channel 724 are connected. After the cooling water enters the connecting chamber 723 through the exchange channel 724, it enters the cooling pipe 843 through the exchange channel 724;

[0048] S4: After the cooling water enters the hollow inner mold base 841 through the cooling pipe 843 and circulates, it flows out from another cooling pipe 843 to achieve circulating cooling; the cooling water forms turbulence inside the inner mold base 841 to improve the heat exchange efficiency; after the cooling water absorbs the heat of the mold, the temperature rises and flows out through the auxiliary cooling pipe 843.

[0049] During the working process of the present invention, the operator selects suitable aluminum alloy raw materials according to production requirements and puts them into the feeding box 4. At this time, the feeding box 4 ensures that the raw materials enter the feeding area accurately and prepares for the subsequent feeding work. After the driving motor 2 is started, it drives the spiral feeding rod 6 to rotate. Through the reduction mechanism, the motor drives the spiral feeding rod 6. The spiral feeding rod 6 adopts a variable pitch design. The front pitch is small to ensure stable feeding, and the rear pitch is large to improve the conveying efficiency. Under the push of the spiral feeding rod 6, the raw materials are evenly transported from the feeding box 4 to the discharging mechanism 7. When the raw materials enter the extrusion channel 712 through the transition channel 711, the driving blades 75 installed in the discharging mechanism 7 are driven to rotate, and the driving gear 76 on the rotating shaft 74 is meshed with the reciprocating teeth 731, driving the control block 73 to move backward. In this way, the control block 73 moves to make the connecting chamber 723 and the exchange channel 724 communicate, and the cooling water enters the connecting chamber 723 through the exchange channel 724, and then flows into the cooling pipe 843 to start the cooling process. The cooling water enters the inner mold base 841 through the cooling pipe 843 and circulates in the hollow structure. The cooling water forms turbulence in the inner mold base 841 to improve the heat exchange efficiency. In this way, the cooling water absorbs the heat of the mold, and after the temperature rises, it flows out through the auxiliary cooling pipe 843, achieving cyclic cooling.

The raw materials are pushed by the screw feeding rod (6) to move evenly toward the discharging mechanism (7); S3: When the raw material enters the extrusion channel (712) through the transition channel (711), the driving blade (75) is driven to rotate, so that the driving gear (76) installed at both ends of the rotating shaft rotates, and the driving gear (76) and the reciprocating teeth (731) mesh and move to drive the control block (73) to move backward, so that the connecting chamber (723) and the exchange channel (724) are connected, and the cooling water enters the connecting chamber (723) through the exchange channel (724), and then enters the cooling pipe (843) through the exchange channel (724); S4: After the cooling water enters the hollow inner mold base (841) through the cooling pipe (843) and circulates, it flows out from another cooling pipe (843) to achieve circulating cooling; the cooling water forms turbulence inside the inner mold base (841) to improve the heat exchange efficiency; after the cooling water absorbs the heat of the mold, the temperature rises and flows out through the auxiliary cooling pipe (843).
