Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy tubular busbar production technology, specifically to a quenching device for aluminum alloy tubular busbars. Background Technology

[0002] In the field of quenching processing of aluminum alloy tubular busbars, existing technologies suffer from several critical issues that urgently need to be addressed. Firstly, traditional quenching equipment has a low degree of automation, relying heavily on manual operation of the cabinet doors, workpiece loading and unloading, and quenching transfer. This not only results in low production efficiency and high costs but also poses significant safety hazards. Furthermore, the limited single-batch processing capacity makes it difficult to meet the demands of large-scale production. Secondly, process parameter control is relatively crude. Key parameters such as quenching temperature, time, and cooling rate lack precise monitoring and dynamic adjustment, leading to unstable performance of the tubular busbars. In addition, unreasonable cooling system design allows the quenching liquid temperature to rise easily due to continuous heating, reducing the cooling rate and further affecting quenching efficiency and uniformity. This can even lead to excessive temperature differences between the workpiece surface and core, generating thermal stress and causing deformation or cracking. Moreover, environmental and safety design is inadequate. Waste gases generated during quenching (such as inhalable particulate matter and toxic gases) are directly emitted, endangering the health of operators. Some equipment lacks necessary safety protection measures, increasing the risk of accidents. Although the industry has made some progress in the process of technological evolution in areas such as cooling system optimization (e.g., the introduction of spiral cooling pipes and heat dissipation tanks), automation integration (e.g., electric motor-driven cabinet doors and hydraulic telescopic platforms), and process parameter control (e.g., the linkage between temperature sensors and controllers), it has not yet effectively integrated core requirements such as automated loading and unloading, precise process control, environmental and safety protection, and adaptation to diverse processes. In view of this, in-depth research was conducted on the above issues, which led to this case. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a quenching device for aluminum alloy tubular busbars, comprising a processing support, a heating box, and a quenching pool. The processing support is installed on the quenching pool, the heating box is installed on the processing support, and a support unloader is installed on the heating box and the quenching pool. A quencher is installed inside the quenching pool, and a heater is installed inside the heating box. The support unloader includes a pair of trapezoidal spliced ​​support blocks, each trapezoidal spliced ​​support block having multiple support grooves. Support rollers are installed on the support grooves. Multiple insert blocks are installed on the trapezoidal spliced ​​support blocks, each trapezoidal spliced ​​support block having multiple insert grooves. A pair of sealed hydraulic doors and a pair of concave fitting boxes are installed on the heating box. The concave fitting boxes are inserted into the side wall of the heating box, and horizontal telescopic support blocks are installed on the concave fitting boxes. The support block is connected to the trapezoidal splicing support block. A pair of horizontal extrusion hydraulic push rods are installed on the inner side of the concave package box. The pushing end of the pair of horizontal extrusion hydraulic push rods is connected to the horizontal telescopic support block. Two pairs of lifting return blocks are installed on the inner side of the heating box. A convex lifting block is installed on the inner side of the pair of lifting return blocks. A lifting and transporting hydraulic push rod is installed on the inner side of the heating box. The pushing end of the lifting and transporting hydraulic push rod is connected to the convex lifting block. A telescopic shaft barrel is installed on the convex lifting block. A telescopic convex shaft is installed on the inner side of the telescopic shaft barrel.

[0004] Preferably, the support unloader further includes an eye-shaped bracket, an eye-shaped insertion slot is provided on the inner side of the quenching pool, the eye-shaped bracket is movably inserted into the inner side of the eye-shaped insertion slot, a plurality of support rollers are installed on the eye-shaped bracket, two pairs of lifting and stretching slots are provided on the side wall of the quenching pool, a stretching hydraulic push rod is installed on the inner side of the two pairs of lifting and stretching slots, the pushing end of the two pairs of stretching hydraulic push rods is connected to the eye-shaped bracket, a drive gear set is installed on the plurality of support rollers, and a stretching drive machine is installed on the drive gear set.

[0005] Preferably, an ultrasonic stirrer is installed on the inner side of the quenching tank.

[0006] The heating chamber is also equipped with a temperature monitoring module and a control module. The temperature monitoring module monitors the temperature inside the heating chamber in real time and transmits the temperature data to the control module. The control module is electrically connected to the heater and compares the received temperature data with a preset temperature range. When the temperature inside the heating chamber is lower than the lower limit of the preset temperature range, the control module controls the heater to increase the heating power; when the temperature inside the heating chamber is higher than the upper limit of the preset temperature range, the control module controls the heater to decrease the heating power or stop heating, thereby ensuring that the temperature inside the heating chamber remains stable within a suitable range and guaranteeing the heating quality of the aluminum alloy tubular busbar. Simultaneously, the control module is also electrically connected to the pair of sealing hydraulic doors. Before the heating operation begins, the control module controls the sealing hydraulic doors to close and checks their sealing status. If a leak is detected, the control module issues an alarm signal to remind the operator to check and handle the issue, preventing heat loss due to sealing problems and affecting the heating effect. Preferably, the quenching tank is equipped with a liquid level monitoring device and a temperature regulating device. The liquid level monitoring device is used to monitor the liquid level of the quenching medium in the quenching tank in real time and transmit the liquid level data to the control module. The control module has a preset safe liquid level range. When the monitored liquid level is lower than the lower limit of the safe liquid level range, the control module issues a liquid level shortage alarm signal to remind the operator to add quenching medium in time. When the liquid level is higher than the upper limit of the safe liquid level range, the control module issues a liquid level over-limit alarm signal to prevent the quenching medium from overflowing. The temperature regulating device is electrically connected to the control module and is used to regulate the temperature of the quenching medium in the quenching tank. The control module controls the temperature regulating device to adjust the temperature of the quenching medium to a suitable range according to the preset quenching process requirements, and monitors and adjusts the temperature in real time during the quenching process to ensure that the aluminum alloy tubular busbar is in a stable quenching temperature environment during the quenching process, thereby improving the quenching quality. In addition, the side wall of the quenching tank is also provided with a heat insulation layer to reduce the heat exchange between the quenching tank and the external environment, further stabilizing the temperature of the quenching medium. A preferred processing rack is equipped with an operation control panel, which is electrically connected to the control module. Operators can input various process parameters such as heating temperature, heating time, quenching medium temperature, and liquid level, as well as control commands for starting, stopping, and operating various components, through the operation control panel. The operation control panel is equipped with a display screen to show the device's operating status, various monitoring data (such as heating chamber temperature, quenching tank liquid level and temperature), and alarm information, allowing operators to monitor the device's operation in real time. Simultaneously, the device is equipped with safety protection devices, including protective railings around the heating chamber and quenching tank to prevent operators from accidentally contacting high-temperature components or the quenching medium and suffering burns or other injuries. The electrical system of the device is equipped with a leakage current protection device; when leakage is detected, the leakage current protection device quickly cuts off the power supply to ensure the operator's safety. Furthermore, the device is equipped with an emergency stop button; in case of a sudden emergency, the operator can press the emergency stop button to immediately stop the device and prevent the accident from escalating.

[0011] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0012] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0013] Example Please see Figure 1-2 Traditional quenching equipment (such as closed quenching furnaces or quenching boxes) has a fixed volume and limited single-batch processing capacity, requiring manual loading and unloading, resulting in low production efficiency and high costs. During the quenching process, the temperature of the quenching liquid is prone to rise due to continuous heating of the tubular busbar, leading to a decrease in cooling rate and a prolongation of quenching time, affecting efficiency. Existing equipment mostly relies on manual operation of the box door, workpiece loading and unloading, and quenching transfer, posing safety hazards and limiting efficiency. For example, although a certain patent uses an electric motor to drive the box door, it does not integrate workpiece handling with process parameter control. Therefore, this application protects a quenching device for aluminum alloy tubular busbars. The device transports the aluminum alloy tubular busbar to a pair of trapezoidal splicing support blocks 3, on which multiple support grooves 4 are located on support rollers 5. The horizontal telescopic hydraulic push rod 16 inside the concave housing 8 extends and retracts, driving the horizontal telescopic support block 9 at its pushing end. This causes the horizontal telescopic support block 9 to stably extend and retract horizontally along the inner side of the concave housing 8. The horizontal telescopic support block 9 drives the trapezoidal splicing support block 3 above it, and the device inserts... Inserting block 6 into the inner side of the insertion slot 7, thereby interlocking and fixing a pair of trapezoidal splicing support blocks 3. Simultaneously, multiple support rollers 5 support the aluminum alloy tubular busbar. A heater heats the aluminum alloy tubular busbar, and a pair of sealed hydraulic doors seal the heating box 1. The lifting and transporting hydraulic push rod 13 extends and retracts, driving the convex lifting block 12 on the pushing end. This allows the convex lifting block 12 to rise and fall stably on a pair of lifting loop blocks 11. The convex lifting block 12 moves to both sides of the aluminum alloy tubular busbar, and then extends... The horizontal telescopic hydraulic push rod 16 inside the telescopic barrel 14 extends and retracts, driving the telescopic convex shaft 15 on the push end. This causes the telescopic convex shaft 15 to stably extend and retract horizontally along the inner side of the telescopic barrel 14. The electromagnetic expansion joint 18 inside the telescopic convex shaft 15 operates, driving the telescopic cylindrical block 19 on it. This causes the telescopic cylindrical block 19 to extend and retract beyond the inner side of the telescopic groove 17 on the telescopic convex shaft 15. The telescopic ball 20 on the telescopic cylindrical block 19 provides extended support to the inner side of the aluminum alloy tubular busbar, supported by a pair of trapezoidal splicing support blocks 3. The aluminum alloy tubular busbar is contracted, exposing the quenching pool 2 at the bottom of the heating box 1. By loosening the aluminum alloy tubular busbar, it falls into the inner side of the quenching pool 2, thereby achieving rapid sealed quenching of the aluminum alloy tubular busbar. The extension and retraction of the hydraulic push rod drives the eye-shaped support on it to move up and down stably. The eye-shaped support drives the support roller 5 on it. The operation of the stretching drive machine drives the drive end of the stretching drive machine to drive the drive gear set. The drive gear set drives the support roller 5 on it, thereby stretching, lifting and horizontally transporting the aluminum alloy tubular busbar. In summary, initially, the aluminum alloy tubular busbar is transported to the support rollers 5 inside the multiple support slots 4 of a pair of trapezoidal splicing support blocks 3. Subsequently, the horizontal telescopic hydraulic push rod 16 inside the concave set box 8 extends and retracts, causing the horizontal telescopic support block 9 to stably extend and retract horizontally along the inner side of the concave set box 8. This, in turn, causes the trapezoidal splicing support block 3 to insert the insertion block 6 into the insertion slot 7, so that the pair of trapezoidal splicing support blocks 3 are mutually inserted and fixed. The multiple support rollers 5 support the aluminum alloy tubular busbar, which ensures that the position of the aluminum alloy tubular busbar remains stable during subsequent heating and other operations, and will not shift due to equipment vibration or other factors, thus ensuring processing accuracy. Next is the heating process. The heater heats the aluminum alloy tubular busbar, while a pair of sealed hydraulic doors seal the heating chamber 1. Before heating, the sealing performance of the heating chamber 1 should be checked to ensure that the sealed hydraulic doors can close normally without any air leakage, so as to ensure a stable heating environment and improve heating efficiency and quality. Because the sealed heating chamber 1 can reduce heat loss, the aluminum alloy tubular busbar is heated in a relatively constant temperature environment, ensuring that it is heated evenly and avoiding local insufficient temperature due to heat loss, which would affect the quenching effect. Next is the handling of the aluminum alloy tubular busbar. The lifting and handling hydraulic push rod 13 extends and retracts, causing the convex lifting block 12 on the pushing end to rise and fall stably within a pair of lifting loop blocks 11. This moves the convex lifting block 12 to both sides of the aluminum alloy tubular busbar. Before the convex lifting block 12 moves to both sides of the aluminum alloy tubular busbar, the positions of the telescopic shaft barrel 14 and the telescopic convex shaft rod 15 must be adjusted to ensure that the telescopic convex shaft rod 15 can accurately reach the appropriate position to provide extended support for the aluminum alloy tubular busbar. The horizontal telescopic hydraulic push rod 16 inside the telescopic shaft barrel 14 extends and retracts, causing the telescopic convex shaft rod 15 on the pushing end to extend and retract stably horizontally along the inner side of the telescopic shaft barrel 14. The electromagnetic expansion joint 18 inside the convex shaft 15 operates, driving the telescopic cylindrical block 19 to extend and expand out of the telescopic groove 17 on the convex shaft 15. The telescopic ball 20 on the telescopic cylindrical block 19 provides extended support to the inner side of the aluminum alloy tubular busbar. During the extension support process, the operating status of the electromagnetic expansion joint 18 must be monitored in real time to prevent abnormal extension and contraction of the telescopic cylindrical block 19. Through the combined operation of lifting and conveying, horizontal extension and expansion support, the heated aluminum alloy tubular busbar can be accurately moved from the heating position to a suitable position to prepare for subsequent quenching. At the same time, the extension support method can avoid damage to the surface of the aluminum alloy tubular busbar.Next is the quenching process. A pair of trapezoidal splicing support blocks 3 retract, exposing the quenching pool 2 at the bottom of the heating box 1, loosening the aluminum alloy tubular busbar and allowing it to fall into the quenching pool 2, achieving rapid sealed quenching. Before the aluminum alloy tubular busbar falls into the quenching pool 2, it is necessary to check whether the temperature, liquid level, and other parameters of the quenching medium in the quenching pool 2 meet the requirements. During the falling process, the retraction speed of the trapezoidal splicing support blocks 3 should be controlled to ensure that the aluminum alloy tubular busbar falls smoothly into the quenching pool 2. Rapid falling into the quenching pool 2 allows the aluminum alloy tubular busbar to cool down quickly, achieving the quenching effect, improving its structure and properties. Sealed quenching can reduce the heat exchange between the quenching medium and the external environment, ensure the temperature stability of the quenching medium, and improve the quenching quality. Finally, the aluminum alloy tubular busbar is stretched, lifted, and transported horizontally. The stretching hydraulic push rod extends and retracts, driving the eye-shaped support on it to rise and fall stably. The eye-shaped support drives the support roller 5 on it. The stretching drive motor runs, driving the drive end of the stretching drive motor to drive the gear set. The drive gear set drives the support roller 5 on it, thereby stretching, lifting, and transporting the aluminum alloy tubular busbar horizontally. Before stretching, lifting, and transporting horizontally, the stretching hydraulic push rod, stretching drive motor, and other equipment must be inspected and adjusted to ensure normal operation. During transportation, the speed and force of stretching, lifting, and horizontal transport must be reasonably controlled according to the specifications and processing requirements of the aluminum alloy tubular busbar. Through stretching, lifting, and horizontal transport operations, the quenched aluminum alloy tubular busbar can be further processed, such as adjusting its shape and position, to meet different processing needs, and it can also prepare for subsequent processing steps.
