They do not indicate that the device referred to must have a specific direction or operate in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] A copper-clad aluminum alloy and welding equipment and process thereof, such as Figure 1 As shown, it includes a welding table body 1, on which an operation panel 2 is provided. The welding table body 1 is the base of the entire welding system, and is made of steel. Since the steel is strong and durable, it can withstand high temperatures and heavy loads during the welding process, and the steel also has good thermal stability and deformation resistance, which ensures that the welding table body 1 is strong and durable, making it strong enough to support all equipment and operations during the welding process, while also extending its service life. The operation panel 2 is an interface for the operator to interact with the welding system, and it includes various control buttons, switches, display screens and touch screens, which are used to start the welding process, adjust parameters, monitor the welding status, etc.

[0026] A cavity is provided in the welding table body 1, and a cooling device and an alarm device 3 are provided in the cavity. The cooling device includes a cooling barrel 4 for placing coolant. A positioning plate 5 and a limiting plate 6 are provided on the outer peripheral wall of the cooling barrel 4. A button switch 7 for driving the alarm device 3 to sound an alarm is provided between the positioning plate 5 and the limiting plate 6. An elastic member is provided between the positioning plate 5 and the limiting plate 6. The button switch 7 is triggered by the positioning plate 5 and the limiting plate 6 approaching each other. By providing a cooling device, the heat generated during the welding process can be effectively controlled to prevent the equipment from overheating, thereby protecting the equipment and improving the welding quality. By providing an alarm device 3, when an abnormal situation occurs during the welding process, such as excessive temperature, insufficient coolant or blockage of the coolant, the alarm device 3 can be used. An alarm is sounded to remind the operator to take measures to avoid accidents. By setting the positioning plate 5 and the limiting plate 6, when the coolant in the cooling barrel 4 leaks, that is, the overall weight of the cooling barrel 4 and the coolant becomes lighter, the positioning plate 5 and the limiting plate 6 will approach each other until they support the button switch 7 and open it. At this time, the button switch 7 will drive the alarm device 3 to sound an alarm and inform the operator, so that the operator can close the welding table body 1 in time, avoiding the problem of shortening the service life of the equipment due to the excessively high internal temperature of the welding table body 1. At the same time, the alarm is triggered by the physical displacement between the positioning plate 5 and the limiting plate 6, which reduces the risk of equipment damage and does not require complex electronic sensors, thereby reducing the failure rate.

[0027] Specifically, the elastic member is an elastic rope 13, and a plurality of symmetrically arranged columns 12 are provided on the surface where the positioning plate 5 and the limiting plate 6 face each other. The two ends of the elastic rope 13 are respectively connected to the corresponding two columns 12. When the cooling barrel 4 is full of coolant, the distance between the positioning plate 5 and the limiting plate 6 is greater than the height of the button switch 7. When the cooling barrel 4 is partially filled with coolant or is empty, the distance between the positioning plate 5 and the limiting plate 6 is less than the height of the button switch 7. When the coolant level drops to a certain height, the positioning plate 5 and the limiting plate 6 will approach each other due to the tension of the elastic rope 13, triggering the button switch 7 and automatically sounding an alarm. By using the elastic rope 13 and a simple mechanical structure, the use of electronic components can be reduced, reducing costs and maintenance difficulties. By ensuring that the coolant level is always within a safe range, overheating of the equipment due to insufficient cooling can be prevented, thereby improving the safety of the entire welding system. The design can adapt to cooling barrels 4 of different sizes and shapes and has good versatility.

[0028] Furthermore, the limiting plate 6 and the positioning plate 5 are both provided with a connecting block 15, and the positioning plate 5 and the limiting plate 6 are provided with a groove 14 for accommodating the connecting block 15 to be embedded, and the connecting block 15 is rotatably connected in the groove 14 by a rotating shaft, and the column 12 includes a fixing portion 16 and a disassembly portion 17, and the fixing portion 16 is provided with an internal thread, and the disassembly portion 17 is provided with an external thread matching the internal thread, and the end of the disassembly portion 17 away from the external thread is connected to the elastic rope 13, and when the fixing portion 16 is rotated to a horizontal state, the fixing portion 16 is located in the groove 14, and the fixing portion 16 and the disassembly portion 17 of the column 12 are designed to allow quick installation and disassembly, and the internal thread of the fixing portion 16 and the external thread of the disassembly portion 17 make it easy to fix the column 12 in the positioning The plate 5 and the limiting plate 6 are mounted on the plate 5 and the limiting plate 6 without the need for additional tools, which simplifies the installation process and improves operational efficiency. The design of the connecting block 15 and the groove 14 connected by the rotating shaft can conveniently adjust the positions of the positioning plate 5 and the limiting plate 6 to adapt to cooling barrels 4 of different sizes or different installation requirements. At the same time, since the fixing part 16 is located in the groove 14 when the fixing part 16 is rotated to a horizontal state, the fixing part 16 can be stored and protected by the groove 14 during transportation of the positioning plate 5 and the limiting plate 6, thereby avoiding damage to the fixing part 16. When the positioning plate 5 and the limiting plate 6 are installed, the fixing part 16 will be pulled out of the groove 14 and set vertically under the action of the elastic rope 13, thereby ensuring the stability of the equipment.

[0029] A circulating pump 10 is provided in the welding table body 1, and the circulating pump 10 is connected to the cooling barrel 4 through a pipe 11. The circulating pump 10 can continuously extract the coolant from the cooling barrel 4 and circulate it through the pipe 11 system to form a closed loop, so that the coolant flow rate in the cooling barrel 4 remains stable, ensuring the cooling effect of the cooling device and ensuring that the welding area is continuously cooled, thereby improving the welding quality. Two symmetrically arranged data collectors 8 and comparators 9 are provided on the cooling barrel 4. The value of the comparator 9 is the difference between the coolant flow rates collected by the two flow meters, which is used to determine whether the flow rate is uniform. The threshold value of the comparator 9 is V. When the data collected by the comparator 9 is When it is greater than or equal to its threshold, the alarm device 3 sounds an alarm. Specifically, the data collector 8 is a flow meter, which is used to collect the flow rate of the coolant in the cooling barrel 4. Through the above-mentioned setting, when blockage occurs in the cooling barrel 4, the coolant flow rate monitored by the flow meter on one side will decrease, while the flow side on the other side monitors the coolant flow rate output from the circulating pump 10 through the pipeline 11, thereby generating a difference between the two. After receiving the difference, the comparator 9 compares it and issues an alarm to inform the operator that the cooling barrel 4 has a fault. By promptly discovering and solving problems in the cooling system, equipment damage and maintenance costs caused by uneven cooling can be reduced.

[0030] The welding table body 1 is also provided with an automatic wire feeding device and a welding gun; Automatic wire feeding device, which automatically adjusts the wire feeding speed and wire feeding amount according to welding requirements to ensure uniform fusion of materials during welding The welding gun is responsible for performing the actual welding operation.

[0031] The operation of the welding station body 1 includes the following steps: S1: Start the welding table body 1, start the welding table through the operation panel 2, and perform a system self-check to ensure that all components including the automatic wire feeding device and the welding gun are in normal working condition; S2: Input welding parameters through the operation panel 2, including but not limited to welding current, voltage, wire feed speed, welding path, etc.; S3: Place the copper-clad aluminum alloy material to be welded at the designated position on the welding table, ensure that the material is fixed and stable, start the automatic wire feeding device, and start feeding the wire according to the preset welding parameters; S4: The welding gun starts to perform the welding operation according to the instruction of the operation panel 2; S5: During the welding process, if the cooling system detects any abnormality, leakage or blockage occurs in the cooling barrel 4, an alarm will be sounded to ensure the safety and quality of the welding process; S6: After welding is completed, the welding gun automatically stops the welding operation, and the automatic wire feeding device also stops feeding the wire synchronously, and the welding program is ended through the operation panel 2.

[0033] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
