[0002] Copper busbar is also called copper busbar. It is an indispensable conductive material for manufacturing motor windings, high and low voltage electrical appliances, switch contacts, and wires for power distribution installation.

[0003] Copper busbars have high mechanical properties, good electrical and thermal conductivity, excellent corrosion resistance, electroplating and brazing properties, beautiful metallic luster and good forming and processing properties. Therefore, various power transmission and transformation equipment and electrical equipment made of them have been widely used in the power field. In recent years, with the continuous and rapid development of the national economy, the production and consumption of copper busbars in my country have also increased significantly, and the quality requirements for copper busbars have also been continuously improved.

When the copper busbars are shaped, cutting is mostly used for cutting and shaping. The cutting process is mostly performed by manual cutting or mechanical cutting. However, whether it is manual cutting or mechanical cutting, it requires multiple and multi-sided cutting work before shaping. This shaping method is inefficient and reduces the overall production speed of the copper busbar production. Therefore, the utility model proposes a motor cam driven copper busbar one-time forming punching machine. Utility Model Content

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] See also Figure 1-5The utility model provides an embodiment: a motor cam driven copper bar forming and punching machine, comprising a frame 1, a punching motor 3 fixedly installed inside the frame 1, the output end of the punching motor 3 is fixedly connected to the input end of a gear transmission box 4, the gear transmission structure inside the gear transmission box 4 is a right-angle connection gear of a bevel gear and a bevel gear, the output ends on both sides of the gear transmission box 4 are fixedly connected to cams 5 through a rotating shaft, and connecting rods 6 are rotatably installed on the two cams 5, and a driving plate 7 is rotatably installed between the top ends of the two connecting rods 6;

[0026] According to the above structure, when the punching motor 3 rotates, it drives the cams 5 on both sides to rotate through the output shaft and the gear transmission box 4. When the cams 5 rotate, the connecting rods 6 connected to them will move up and down on them, thereby driving the driving plate 7 to move up and down through the effect of the cams 5 and the connecting rods 6.

[0027] Guide columns 8 are fixedly installed at the four corners of the lower surface of the driving plate 7. An upper die base 9 is slidably connected between the four guide columns 8. A protruding die head is provided below the upper die base 9. The upper die base 9 and the driving plate 7 are fixedly connected by a number of buffer springs 10. A lower die base 11 is provided below the upper die base 9. A die cavity 12 is provided in the middle position of the upper surface of the lower die base 11. The die head and the die cavity 12 are adapted in size and structure. The lower die base 11 is fixedly mounted on the frame 1. The four guide columns 8 all pass through the lower die base 11 design, and the guide columns 8 are slidably connected to the lower die base 11.

[0028] With this structural design, when the driving plate 7 is lifted up and down, it will drive the upper die base 9 below to perform synchronous lifting and lowering work through the buffer spring 10. When the upper die base 9 descends and contacts the lower die base 11, it will punch and cut the copper bar coil between the two. In this way, the copper bar coil can be punched into the die cavity 12 when the upper die base 9 contacts the lower die base 11, so that the shape of the die cavity 12 can complete the punching and forming of the copper bar into the specified shape, which has the effect of one-time punching and forming.

[0029] When the upper die base 9 contacts the lower die base 11, the upper die base 9 will compress the buffer spring 10 due to the contact pressure. The compression of the buffer spring 10 can play a certain force buffering role when the upper die base 9 contacts the lower die base 11, avoiding collision damage to the die base during the punching process, improving the buffering effect during punching, better protecting the die base, and increasing its service life.

[0030] In this embodiment, in order to provide external protection for the punching structure of the driving plate 7 and improve processing safety, a protective cover 2 is provided on the outer cover of the driving plate 7, and the protective cover 2 is fixedly mounted on the upper surface of the frame 1;

[0031] In this embodiment, in order to convey and export the formed materials after punching, a conveyor belt 13 is provided below the lower die base 11. The materials after punching and forming will fall onto the conveyor belt 13. The conveyor belt 13 can convey and export the fallen materials, thus completing the forming and removing work of the copper bar materials.

[0032] In this embodiment, in order to rewind and recycle the copper bar production coil, a scrap recovery rack 14 is provided on one side of the front end of the conveyor belt 13. A scrap motor is installed on the top of the scrap recovery rack 14. The output shaft of the scrap motor is fixedly connected to the reeling shaft 15. The scrap motor can drive the reeling shaft 15 to rotate and rewind, so that the copper bar coil after punching can be rewound, which is convenient for secondary forging and utilization, thereby improving the utilization efficiency of the structure.

[0033] In this embodiment, in order to ensure the normal feeding of the copper bar forming material coil, a feed roller 16 is installed at the tail end of the frame 1 through a rotating shaft;

[0034] Furthermore, a feed frame 17 is fixedly mounted on the feed end of the lower die base 11, and two feed rollers 18 are rotatably mounted on the feed frame 17 through bearings, wherein the shaft of one of the feed rollers 18 is connected to the output shaft of the feed motor 19;

[0035] With this structural design, the tail end of the punching machine can be used to place the unwinding device of the copper bar coil, and one end of the copper bar coil used for production enters through the feed roller 16, then passes between the two feed rollers 18, passes between the upper die base 9 and the lower die base 11, and is then fixed on the reel 15. Figure 5 As shown;

[0036] In this way, the unwinding and rewinding structures are used in conjunction to complete the rotary feeding of the copper bar coil. After a single punching is completed, the unwinding and feeding is performed once, thereby completing the cyclic punching processing work.

[0037] The coiled material after punching and cutting can be rotated and recovered by the reel 15, so that the coiled material after punching and cutting can be recycled, thereby improving resource utilization efficiency, reducing production costs, and having a better use effect.

[0038] Working principle: When the utility model is in use, the unwinding device of the copper bar coil can be placed at the tail end of the punching machine, and one end of the copper bar coil used for production enters through the feed roller 16, then passes between the two feed rollers 18, passes between the upper die base 9 and the lower die base 11, and is then fixed on the reel 15. The specific coil feeding direction is as shown in the attached manual. Figure 5 As shown;

[0039] In this way, the unwinding and rewinding structures are used in conjunction to complete the rotary feeding of the copper bar coil. After a single punching is completed, the unwinding and feeding is performed once, thereby completing the cyclic punching processing work.

[0040] During actual punching, the punching motor 3 can be rotated. When the punching motor 3 rotates, it drives the cams 5 on both sides to rotate through the output shaft and the gear transmission box 4. When the cam 5 rotates, the connecting rod 6 connected to it will move up and down on it, thereby driving the driving plate 7 to move up and down through the effect of the cam 5 and the connecting rod 6;

[0041] When the driving plate 7 moves up and down, it will drive the upper die base 9 below to move up and down synchronously through the buffer spring 10;

[0042] Among them, when the upper die base 9 descends and contacts the lower die base 11, the die head will punch into the die cavity 12 of the lower die base 11, so that the copper busbar coil between the two is punched and formed by the cooperation of the die head and the die cavity 12. The provided die cavity 12 can be used as a forming cavity of a specified shape. When the upper die base 9 descends and contacts the lower die base 11, the punching and forming of the copper busbar into the specified shape is completed by the cooperation of the die cavity 12 and the die head, which has the effect of one-time punching and forming.

[0043] After the punching is completed, the material falls freely onto the conveyor belt 13, so that the copper busbar formed material can be transported and discharged through the conveyor belt 13;

[0044] After a single punching is completed, the punching motor 3 rotates a certain angle, thereby driving the upper die base 9 to move upward through the cam 5 and the connecting rod 6;

[0045] At this time, the unwinding device and the reel 15 are working, thereby recycling a part of the coil to the reel 15. During the recycling process, the coil at the tail end will be transported a certain distance, so that the new coil surface can be placed between the upper die base 9 and the lower die base 11. At this time, the punching motor 3 rotates again, driving the lower die base 9 to complete a new round of downward pressure punching processing, thereby completing the reciprocating copper busbar punching processing work.

[0046] According to the above description, the motor cam driven copper busbar forming and punching machine of the present invention can drive the lower die base to perform reciprocating lifting and lowering motion through the coordinated use of the motor, cam and connecting rod, thereby completing the forming and pressing punching process of the copper busbar production, and can complete the forming and punching of the specified size in a single pressing operation. Compared with the existing cutting and forming, the present invention can complete the punching process of the copper busbar with the specified outer contour in a shorter time through the punching and forming processing method, and the outer contour can be formed in one time without multiple trimming and cutting, 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.

[0047] 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.

[0048] 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.
