Description

Technical Field

[0001] This utility model relates to the field of conductive copper busbar production technology, specifically a conductive copper busbar punching machine. Background Technology

[0002] Conductive copper busbars are a type of strip conductor material processed through a specific process. Their surface is usually plated with an anti-oxidation and anti-corrosion metal coating to prevent oxidation and corrosion, thereby improving conductivity and service life.

[0003] Conductive copper busbars are mainly used in conductor equipment for transmitting high currents. They possess excellent conductivity and mechanical strength, and are widely used in power electronics, communication electronics, new energy power, railway transportation, and marine engineering.

[0004] Conductive copper busbars require punching during production, which necessitates the use of a punching machine. Traditional punching machines, when performing hydraulic punching on conductive copper busbars, often result in the ends of the busbars lifting up due to the lack of clamping and anti-jumping devices on both sides. This lifting can potentially damage personnel or objects, posing a certain processing hazard. Therefore, this utility model proposes a punching machine that can clamp and prevent the conductive copper busbars from lifting. Utility Model Content

[0005] The purpose of this invention is to provide a conductive copper busbar punching machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a conductive copper busbar punching machine, comprising a working base plate, a punching table fixedly installed at the center of the upper surface of the working base plate, a support column fixedly installed on the back of the punching table, the support column adopting an "L" shaped structure design, a punching top plate fixedly installed at the top of the support column, lower roller supports fixedly installed on both outer walls of the punching table, a plurality of lower pressing rollers rotatably installed in the lower roller supports via a rotating shaft, the plurality of lower pressing rollers being linearly distributed at equal intervals, side extension plates fixedly installed on both outer walls of the punching top plate, at least two sets of pressing cylinders fixedly installed on the side extension plates via bolts, the output end of the pressing cylinders being connected to pressing telescopic rods, an upper roller support fixedly installed between the bottom ends of the plurality of pressing telescopic rods, a plurality of upper pressing rollers rotatably installed in the upper roller support via a rotating shaft.

[0007] Preferably, the upper pressing roller and the lower pressing roller are arranged in a mirror image opposite each other, and a plurality of the upper pressing rollers are linearly distributed at equal intervals.

[0008] Preferably, a punching cylinder is fixedly installed at the center of the upper surface of the punching top plate, and a punching telescopic rod is movably connected to the output end of the punching cylinder.

[0009] Preferably, a punching head is fixedly installed at the bottom end of the punching telescopic rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model uses a clamping cylinder to drive a clamping telescopic rod to extend and retract normally. When the clamping telescopic rod extends, the upper roller bracket at the bottom of the clamping telescopic rod can be lowered, thereby reducing the distance between the upper and lower clamping rollers. The upper and lower clamping rollers on both sides can clamp the two ends of the conductive copper busbar to prevent it from jumping, thus preventing the two ends of the conductive copper busbar from lifting up during punching, improving the safety of punching, reducing safety hazards, and having a good clamping and anti-jumping effect.

[0012] The distance between the upper and lower clamping rollers can be controlled by adjusting the extension length of the clamping telescopic rod. This allows for effective adjustment of the clamping force between the upper and lower clamping rollers during actual use, providing a dynamic adjustment feature to prevent jumping. It is also suitable for punching and clamping conductive copper busbars of varying thicknesses. In practical use, it offers dynamically adjustable clamping force and a wide range of applicable thicknesses, effectively improving the flexibility of the structure, reducing usage limitations, and featuring a simple overall structure with low manufacturing and maintenance costs, making it suitable for widespread application.

For example, "connected" can be 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; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-4 The present invention provides an embodiment of a conductive copper busbar punching machine, comprising a working base plate 1, a punching table 2 fixedly installed at the center of the upper surface of the working base plate 1, a support column 5 fixedly installed on the back of the punching table 2, and a punching top plate 6 fixedly installed at the top of the support column 5. The support column 5 adopts an "L" shaped structure design, so that the punching top plate 6 and the support column 5 can be used as the overall frame of the punching mechanism.

[0022] Lower roller supports 3 are fixedly installed on both outer walls of the punching table 2. Several lower pressing rollers 4 are rotatably installed inside the lower roller supports 3 via a rotating shaft. The lower pressing rollers 4 are linearly distributed at equal intervals. The lower pressing rollers 4 can ensure the bottom contact effect with the conductive copper busbar. The rolling connection of the lower pressing rollers 4 can ensure normal rolling contact with the conductive copper busbar during pressing, ensuring that the conductive copper busbar can be rolled and fed under the action of the external feeding structure.

[0023] Side extension plates 7 are fixedly installed on both outer walls of the punched top plate 6. At least two sets of clamping cylinders 8 are fixedly installed on the side extension plates 7 by bolts. The output end of the clamping cylinder 8 is connected to a clamping telescopic rod 9. An upper roller bracket 10 is fixedly installed between the bottom ends of several clamping telescopic rods 9. Thus, the clamping cylinder 8 can drive the upper roller bracket 10 to perform up and down lifting work through the clamping telescopic rod 9. Several upper clamping rollers 11 are rotatably installed inside the upper roller bracket 10 through a rotating shaft.

[0024] Furthermore, the upper pressing roller 11 and the lower pressing roller 4 are arranged in mirror image opposite each other, and a plurality of upper pressing rollers 11 are linearly distributed at equal intervals;

[0025] Based on the above structure, the clamping cylinder 8 can drive the clamping telescopic rod 9 to perform normal extension and retraction. When the clamping telescopic rod 9 extends, the upper roller bracket 10 at the bottom of the clamping telescopic rod 9 can be lowered, thereby reducing the distance between the upper clamping roller 11 and the lower clamping roller 4. Thus, the upper clamping roller 11 and the lower clamping roller 4 on both sides can perform anti-jump clamping work on both ends of the conductive copper busbar, preventing the conductive copper busbar from tilting up at both ends during punching, improving the safety of punching processing, reducing safety hazards, and having a good clamping and anti-jumping effect.

[0026] The distance between the upper clamping roller 11 and the lower clamping roller 4 can be controlled by adjusting the extension length of the clamping telescopic rod 9. In actual use, the clamping force between the upper clamping roller 11 and the lower clamping roller 4 can be freely adjusted, thus providing the technical characteristics of dynamic adjustment of clamping force to prevent jumping. It can also be used for punching and clamping conductive copper busbars of different thicknesses. In actual use, it has the practical effect of dynamically adjustable clamping force and wide range of applicable thicknesses, effectively improving the flexibility of structural use, reducing usage limitations, and the overall structure is simple with low manufacturing and maintenance costs, making it suitable for widespread use.

[0027] In this embodiment, in order to ensure the normal punching effect of this utility model, a punching cylinder 12 is fixedly installed at the center of the upper surface of the punching top plate 6, and a punching telescopic rod 13 is movably connected to the output end of the punching cylinder 12.

[0028] Furthermore, a punch head 14 is fixedly installed at the bottom end of the punch telescopic rod 13;

[0029] With this structural design, the punching cylinder 12 can drive the punching head 14 to descend and punch through the punching telescopic rod 13, thereby ensuring normal punching of conductive copper busbars.

[0030] Working principle: In actual use, the conductive copper busbar needs to be connected to a uniform feeding mechanism to ensure the normal punching and feeding of the conductive copper busbar.

[0031] During punching, the conductive copper busbar enters from one side of the punching machine through an external uniform feeding mechanism. After entering, the conductive copper busbar is placed between the lower clamping roller 4 and the upper clamping roller 11. Since the upper and lower clamping rollers are all installed on the roller support in a rolling manner, the rolling connection of the clamping rollers can ensure normal rolling contact with the conductive copper busbar during clamping, ensuring that the conductive copper busbar can perform rolling feeding under the action of the external feeding structure.

[0032] When the conductive copper busbar enters between the lower clamping roller 4 and the upper clamping roller 11, the clamping cylinder 8 can work. The clamping cylinder 8 can drive the clamping telescopic rod 9 to perform normal extension and retraction. When the clamping telescopic rod 9 extends, the upper roller bracket 10 at the bottom of the clamping telescopic rod 9 can be lowered, thereby reducing the gap between the upper clamping roller 11 and the lower clamping roller 4, thus clamping and preventing the conductive copper busbar from jumping.

[0033] When the conductive copper busbar enters the punching table 2, the punching cylinder 12 can drive the punching head 14 to descend and punch through the punching telescopic rod 13, thereby ensuring the normal punching operation of the conductive copper busbar and the normal use of this utility model.

[0034] During the continuous feeding operation of the external feeding structure, the punched conductive copper busbar can pass through the gap between the lower clamping roller 4 and the upper clamping roller 11 at the other end to ensure the discharge effect.

[0035] According to the above description, the present invention can perform anti-jump clamping work on both ends of the conductive copper busbar by means of the upper clamping roller and the lower clamping roller arranged on both sides, so as to avoid the situation that the two ends of the conductive copper busbar will lift up when punching, improve the safety of punching process, reduce safety hazards, and have a good clamping and anti-jumping effect.

[0036] The distance between the upper and lower clamping rollers can be controlled by adjusting the extension length of the clamping telescopic rod. This allows for effective adjustment of the clamping force between the upper and lower clamping rollers during actual use, providing a dynamic adjustment feature to prevent jumping. It is also suitable for punching and clamping conductive copper busbars of varying thicknesses. In practical use, it offers dynamically adjustable clamping force and a wide range of applicable thicknesses, effectively improving the flexibility of the structure, reducing usage limitations, and featuring a simple overall structure with low manufacturing and maintenance costs, making it suitable for widespread application.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
