[0024] See also Figure 1-3 The utility model provides an embodiment: a gas-liquid driven copper bar forming and punching machine, comprising a machine base 1, a machine table 2 is fixedly mounted on one side of the upper surface of the machine base 1, an outer shield 3 is fixedly mounted on the upper surface of the machine table 2, a fixing plate 4 is fixedly mounted on the top of the outer shield 3, a driving cylinder 5 is mounted on the fixing plate 4, and the driving cylinder 5 is one of a pneumatic cylinder or a hydraulic cylinder;

[0025] The output end of the driving cylinder 5 is telescopically connected to a driving rod 6, and guide columns 20 are fixedly installed at the four corners of the fixed plate 4. The bottom end of the driving rod 6 is fixedly installed with an upper template 7, and the four corners of the upper template 7 are slidably connected to the four guide columns 20. An upper die base 8 is fixedly installed below the upper template 7, and a punching die head 9 is fixedly installed at the center of the lower surface of the upper die base 8. A lower template 21 is fixedly installed between the bottom ends of the four guide columns 20, and a lower die base 10 is fixedly installed on the upper surface of the lower template 21. A punching die cavity 11 is opened at the center of the outer surface of the lower template 21 and the lower die base 10;

[0026] With this structural design, when the copper busbar needs to be punched and formed, the driving cylinder 5 can be operated. The driving cylinder 5 drives the driving rod 6 to extend. When the driving rod 6 is extended, it will simultaneously drive the upper template 7 and the upper die base 8 at the bottom to descend, so that the copper busbar production coil between the two can be punched into the punching die cavity 11 of the lower die base 10 through the punching die head 9 below the upper die base 8, thereby completing the punching and forming of the copper busbar into the specified shape through the outer contour design of the punching die head 9 and the punching die cavity 11.

[0027] In this embodiment, in order to facilitate the discharge of the copper bar material after punching, a conveyor belt 12 is provided below the lower template 21. The conveyor belt 12 is fixedly mounted on the machine base 1 through a bracket. The material after punching and forming will fall onto the conveyor belt 12. The conveyor belt 12 can transport and discharge the formed material, thereby completing the forming and material removal work of the copper bar material.

[0028] In this embodiment, in order to facilitate the feeding of the coiled material for punching the copper bar, a primary guide roller 18 is rotatably mounted on the tail end of the upper surface of the machine table 2 through a bearing seat, and a secondary guide roller 19 is fixedly mounted on the machine table 2 between the primary guide roller 18 and the lower die base 10;

[0029] The copper bar coil can pass through the primary guide roller 18 and the secondary guide roller 19 under the action of the external unwinding device and enter between the upper die base 8 and the lower die base 10, thereby completing the material guiding work for the copper bar coil punching production;

[0030] In this embodiment, in order to rewind and recycle the copper bar coil waste after punching, a side frame 13 is fixedly installed on the machine base 1 at one side of the tail end of the conveyor belt 12, a transmission box 14 is fixedly installed on the top of the side frame 13, and a winding motor 15 is fixedly installed on the outer wall of one side of the bottom end of the transmission box 14. A winding shaft 17 is rotatably installed inside the upper part of the transmission box 14 through a bearing, and a driven wheel is fixedly sleeved on the outer end of the tail end of the winding shaft 17;

[0031] Furthermore, the output shaft of the winding motor 15 is fixedly connected to the rotating wheel 16 through a coupling, and the rotating wheel 16 is connected to the driven wheel of the winding shaft 17 through a belt transmission;

[0032] With this structural design, in actual use, one end of the copper bar coil is unwound by the unwinding device, and the unwound coil enters through the primary guide roller 18, then passes through the secondary guide roller 19, and then passes between the upper die base 8 and the lower die base 10, and is finally fixed on the reel 15;

[0033] The winding motor 15 can drive the winding shaft 17 to rotate through the rotating wheel 16 and the belt, so that the copper bar coil after punching and cutting can be wound and recycled through the rotation of the winding shaft 17, thereby improving resource utilization efficiency, reducing production costs, and having a good use effect.

[0034] Working principle: Before use, the unwinding device for the copper bar coil can be placed at the feed end of the tail end of the punching machine, and the copper bar coil for production is fed in through the primary guide roller 18, then passes through the secondary guide roller 19, and then passes between the upper die base 8 and the lower die base 10, and finally fixed on the reel 15. In this way, the unwinding and rewinding structures are used in conjunction with each other to complete the rotary feeding of the copper bar coil. After a single punching is completed, the unwinding and feeding are performed once, thereby completing the cyclic punching process.

[0035] During punching, the driving cylinder 5 can work, and the driving cylinder 5 drives the driving rod 6 to extend. When the driving rod 6 extends, it will synchronously drive the upper template 7 and the upper die base 8 at the bottom to descend, so that the copper bar production coil between the two can be punched into the punching die cavity 11 of the lower die base 10 through the punching die head 9 below the upper die base 8, thereby completing the punching and forming of the copper bar into the specified shape through the outer contour design of the punching die head 9 and the punching die cavity 11;

[0036] After a single punching is completed, the formed material automatically falls onto the conveyor belt 12, so that the copper bar material after punching and forming can be transported and discharged through the conveyor belt 12;

[0037] At this time, the drive cylinder 5 drives the upper die base 8 to rise and reset through the drive rod 6, and the reel 15 and the unwinding device rotate at a certain angle. The reel 15 recycles a part of the coil. During the recycling process, the coil at the feed end will be transported for a distance, so that the new coil surface can be placed between the upper die base 8 and the lower die base 10. At this time, the drive cylinder 5 drives the lower die base 8 to descend again to perform the punching work;

[0038] By performing reciprocating operations in the above manner, the forming process of cyclic punching of the copper busbar can be completed.

[0039] The gas-liquid driven copper bar forming and punching machine of the utility model is driven by the power of the driving cylinder, thereby driving the lower die base to perform reciprocating lifting and lowering movements, thereby completing the forming, pressing and punching processing of the copper bar production. The forming and punching of the specified size can be completed in a single pressing operation, with fast forming speed and high production efficiency.

[0040] Compared with the existing cutting and forming method, the present invention can complete the punching process of the copper busbar's specified outer contour in a shorter time through the punching and forming processing method. The outer contour can be formed in one time without the need for multiple trimming and cutting processes, which greatly improves the forming efficiency of the copper busbar and the overall production speed of the copper busbar, and has a better use effect.

[0041] The utility model can also recycle the copper busbar coil after punching, thereby effectively improving the reuse efficiency of the copper busbar metal, reducing resource loss, improving structural utilization, reducing production costs, meeting the requirements of sustainable environmental protection processing, and having good practicality.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
