Description

Technical Field

[0001] This utility model relates to the field of copper busbar production technology, specifically a copper busbar extrusion forming mechanism. Background Technology

[0002] Traditional extrusion presses rely on manual labor for die changing and positioning, resulting in large positioning errors and easily causing the copper busbar forming dimensions to exceed tolerances. This necessitates repeated adjustments, reducing production efficiency. Furthermore, traditional mechanical locking or bolt fixing methods are prone to loosening due to vibration, affecting the stability of the extrusion process. This patent, however, utilizes an extrusion die changer, employing a lifting threaded rod assembly and a lifting gear assembly to drive a concave insert limiting block for precise positioning. The repulsive force between the extrusion electromagnet and the extrusion magnet pushes a convex telescopic insert block, working in conjunction with a buffer spring, to stably fix the die. Real-time monitoring by a position sensor ensures installation accuracy and reduces manual intervention. Regarding copper busbar heating and temperature control, traditional resistance heating or gas heating suffers from poor temperature uniformity and large temperature gradients inside and outside the copper busbar, easily leading to uneven plastic deformation, cracks, or residual stress. Moreover, it suffers from low heating efficiency, long heating times, and high energy consumption, making real-time temperature feedback control difficult. Therefore, this patent was developed through in-depth research addressing these issues. Utility Model Content

[0013] 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.

[0014] 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. Example

[0015] Please see Figure 1-2 In traditional extrusion press applications, there are significant technical deficiencies in the die replacement and copper busbar heating temperature control processes. Regarding die replacement, the traditional method relies on manual positioning, which not only results in large positioning errors but also easily leads to out-of-tolerance copper busbar forming dimensions due to die installation deviations, requiring repeated adjustments and significantly reducing production efficiency. Furthermore, the fixing methods are unstable; traditional mechanical locking or bolt fixing methods are prone to loosening due to vibration, severely affecting the stability of the extrusion process. Therefore, this application protects a copper busbar extrusion forming mechanism. A pair of tension screw modules operate, driving a loop-shaped tension limiting block. A pair of extrusion hydraulic push rods inside the loop-shaped tension limiting block operate, driving the extrusion stretching blocks on their push ends. This causes the pair of extrusion stretching blocks to extend and retract relative to each other, thus extruding the copper raw material. Simultaneously, a coiled inductive heater inductively heats the copper material, softening the copper busbar. Through extrusion stretching, the copper busbar is stably and horizontally stretched and transported to the inside of the packaging box 3. The lifting drive 11 inside the convex lifting hole 5 on the extrusion limiting block 4 inside the packaging box 3 then moves... The lifting drive motor 11 drives the lifting gear assembly 10 on its drive end, which in turn drives the lifting threaded rod assembly 8, which in turn drives the lifting threaded tube assembly 9, which in turn drives the convex lifting block 6. This causes the convex lifting block 6 to extend and retract stably along the convex lifting hole 5. The convex lifting block 6 drives the concave insert limiting block 7, which in turn limits the replaceable insert limiting plate 13 through the concave horizontal telescopic groove 12 on the concave insert limiting plate 7. When the replaceable insert limiting plate 13 is inserted into the concave horizontal telescopic groove 12, it squeezes the conical block 17. The pressure is achieved by multiple conical blocks 17 arranged in a V-shape, so that when the replaceable insert limiting plate 13 is located at the deepest part of the concave horizontal telescopic groove 12, the multiple conical blocks 17 are evenly inserted into the positioning holes on the replaceable insert limiting plate 13. During insertion, the conical blocks 17 are pressed and extended towards the inner side of the telescopic extrusion groove 14, while the conical blocks 17 drive the convex telescopic insert block 15 on it, and at the same time stretch the buffer spring 16. When the fixed position is reached, the buffer spring 16 is stretched by elastic deformation, thereby achieving verticality. By energizing the extrusion electromagnet 18, the extrusion electromagnet 18 magnetically repels the extrusion magnet 19, thereby pushing a pair of molds into the groove. The magnetic repulsion compression fixation is achieved by the compression magnet 19 driving the convex telescopic insert block 15 on it. The convex telescopic insert block 15 and the conical block 17 on it vertically limit and fix the replaceable insert limiting plate 13. This allows for rapid mold replacement and rapid magnetic repulsion compression fixation of the mold, thereby relatively compressing and fixing the replaceable mold. The cooling tank and external water source are diverted to the atomizing spray pipe by a pump. Multiple atomizing nozzles on the atomizing spray pipe spray the copper busbar with atomized water at both ends. At the same time, the stirring cooling fan diffuses the atomized water around the copper busbar, resulting in rapid cooling. In summary, during the mold installation stage, the extrusion mold changer begins operation. The lifting drive motor 11 drives the lifting gear assembly 10 to rotate, causing the lifting threaded rod assembly 8 to rotate. Since the lifting threaded tube assembly 9 is fitted onto the lifting threaded rod assembly 8 and the convex lifting block 6 is installed on the lifting threaded tube assembly 9, the convex lifting block 6 will move up and down within the convex lifting hole 5, driving the concave insert limiting block 7 to the appropriate position. Next, the mold is positioned and fixed. After the replaceable mold is installed on the replaceable insert limiting plate 13, it is inserted into the concave horizontal telescopic groove 12. The extrusion electromagnet 18 is energized to generate magnetism, which generates a repulsive force with the extrusion magnet 19 on the convex telescopic insert block 15, pushing the convex telescopic insert block 15 to move within the telescopic extrusion groove 14, allowing the conical block 17 to insert into the positioning hole of the replaceable insert limiting plate 13 to achieve initial positioning. The buffer spring 16 ensures accurate positioning, and the position sensor detects whether the replaceable insert limiting plate 13 is inserted in place to ensure accurate mold installation. In the copper busbar pretreatment stage, a coiled inductive heater is installed on the processing support 2 and processing table 1 to heat the copper busbar. Temperature sensors distributed in the heating area monitor the temperature in real time and provide feedback to the control system. The control system adjusts the heating power according to the deviation between the preset and actual temperatures to ensure the copper busbar reaches the appropriate softening temperature. In the copper busbar stretching stage, pairs of stretching screw modules are installed parallel to each other on the processing table 1, with a loop-shaped stretching limit block installed on top. The operation of the stretching screw modules moves the loop-shaped stretching limit block, and a pair of extrusion hydraulic pushers on its inner side push the extrusion stretching block to apply stretching force to the copper busbar. Simultaneously, a tension sensor on the processing support 2 detects the stretching force in real time and provides feedback to the central control unit. The central control unit adjusts the running speed of the stretching screw modules and the thrust of the extrusion hydraulic pushers according to a preset range to ensure smooth stretching. In the copper busbar extrusion stage, the stretched copper busbar is moved to the extrusion die, where a suitable replaceable die has been installed and positioned. With the cooperation of the stretcher and other components, it is extruded into the die to form the desired shape. Finally, during the copper busbar cooling stage, a cooling tank is set up on processing table 1, and atomizing spray pipes installed on it are connected to a cooling water source via a pump. Multiple atomizing nozzles can spray atomized water to cool the copper busbar. Multiple stirring cooling fans installed on processing support 2 can accelerate airflow and enhance the cooling effect. The filter screen in the cooling tank filters impurities. Three valves connect the cooling tank and the atomizing spray pipes, allowing the cooling method to be selected as needed. Temperature sensors continue to monitor temperature changes during the cooling process, and the control system adjusts parameters such as the spray water volume of the atomizing spray pipes and the speed of the stirring cooling fans accordingly, so that the copper busbar is cooled evenly and quickly to reach the appropriate hardness, completing the entire extrusion molding process.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
