Description

Technical Field

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

[0002] A copper busbar punching machine is an industrial device specifically designed for punching copper busbars. This machine typically consists of two main parts: a manual or electric pump and a working head. The punch is driven by a hydraulic system to perform precise punching operations. The design of the copper busbar punching machine enables it to operate efficiently and stably in various working environments, including outdoor construction sites and factory interiors.

[0003] Existing copper busbar punching machines include some smaller models that offer advantages such as small footprint, flexible processing, ease of operation and maintenance, and suitability for small-batch or customized production. However, these smaller punching machines still require manual fixation of the copper busbar during operation. Furthermore, during ejection, the copper busbar may stick to the punch head, requiring continuous hand support until it touches the ejection pad before falling. This can affect punching accuracy due to operator hand movement. Therefore, a new solution is needed to address the issue of operators still needing to hold the copper busbar during production, which affects its stability during punching. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a copper busbar punching machine, which increases the stability of the punching machine during operation by setting a clamping component on the punching support platform.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A copper busbar punching machine includes a base and a hydraulic cylinder. A punching support platform is provided on the base. A punch is installed at the end of the hydraulic cylinder. Several L-shaped support rods are fixedly connected to the side of the punching support platform away from the punch. One end of the support rod connected to the punching support platform is parallel to the punching support platform. The other end of the support rod away from the punching support platform is perpendicular to its other end. A lifting plate is slidably connected between adjacent support rods on the side away from the punching support platform. A clamping plate is rotatably connected to the side of the lifting plate away from the punch. The clamping plate is engaged with the end of the support rod parallel to the punching support platform.

[0006] The present invention is further configured such that: the clamping plate is recessed inward to form a plurality of grooves, and the support rod is inserted into the grooves during use; the length of the grooves is the same as the thickness of one end of the support rod parallel to the punching bearing platform; and the protruding parts between adjacent grooves and the two sides of the support rod that are close to each other are all configured as arcs.

[0007] The present invention is further configured such that: the lifting plate is T-shaped, and the protruding part of the lifting plate is slidably connected to the end of the support rod away from the punch.

[0008] The present invention is further configured such that: the end of the adjacent support rod away from the punch and the opposite side is recessed inward to form a sliding groove; the two ends of the lifting plate in the width direction are slidably connected to the inner wall of the sliding groove; and the bottom surface of the sliding groove is on the same plane as the upper surface of the punching support platform.

[0009] The present invention is further configured such that a buffer sheet is fixedly connected to the side of the lifting plate near the punching support platform, and the buffer sheet has elastic deformation properties.

[0010] The present invention is further configured such that: both sides of the hydraulic cylinder in the width direction are rotatably connected to rotating rods for supporting the lifting platform, and the rotating rods are configured as L-shaped.

[0011] The present invention is further configured such that the distance between the clamping plate and the rotating rod is greater than the distance between the clamping plate and the end of the support rod perpendicular to the punching bearing platform.

[0012] In summary, this utility model has the following beneficial effects: A copper busbar punching machine has several L-shaped support rods on a punching support platform. A lifting plate is slidably connected to the end of the support rod away from the punching support platform. A clamping plate is rotatably connected to the side of the lifting plate away from the punch. After the copper busbar is placed on the support platform, the lower surface of the lifting plate abuts against the copper busbar. The clamping plate is rotated to make the groove engage with the support rod, thereby fixing the copper busbar. A buffer plate is fixedly connected to the side of the lifting plate near the punching support platform to reduce wear on the copper busbar during clamping. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] This type of copper busbar punching machine, such as Figure 1 , Figure 2 As shown, the device includes a base 1 and a hydraulic cylinder 2. A punching support platform 3 is mounted on the base 1. A punch 4 is installed at the end of the hydraulic cylinder 2. When punching is required on a copper busbar, the copper busbar is placed on the punching support platform 3, and the punch 4 moves downwards to punch the copper busbar. Four L-shaped support rods 5 are welded to the side of the punching support platform 3 away from the punch 4. The end of the support rod 5 connected to the punching support platform 3 is parallel to the punching support platform 3, and the upper surface of the end of the support rod 5 connected to the punching support platform 3 is on the same plane as the upper surface of the punching support platform 3, ensuring that the support rod 5 does not affect the placement of the copper busbar on the punching support platform 3. One end of the punching support table 3 is perpendicular to the other end. A lifting plate 6 is slidably connected between two support rods 5 on the same side of the machine base 1 and away from the punching support table 3. A clamping plate 7 is rotatably connected to the side of the lifting plate 6 away from the punch 4. The clamping plate 7 is engaged with the support rod 5 at one end of the punching support table 3. When it is necessary to punch the copper busbar, the copper busbar is placed on the punching support table 3, and the clamping plate 7 is held by hand to apply a pushing force to the lifting plate 6 so that the lifting plate 6 moves downward. When the lower surface of the lifting plate 6 is in contact with the copper busbar, the clamping plate 7 is rotated to engage with the support rod 5, thereby fixing the copper busbar and then processing it.

[0019] like Figure 1 , Figure 2 As shown, the clamping plate 7 is recessed inward to form several grooves 8. In practical use, the operator can insert the support rod 5 into the groove 8 at one end parallel to the punching support table 3. The length of the groove 8 is the same as the thickness of the end of the support rod 5 parallel to the punching support table 3. After rotating the clamping plate 7 downward, the end of the support rod 5 parallel to the punching support table 3 is inserted into the groove 8 to fix the position of the clamping plate 7. The several grooves 8 on the clamping plate 7 can be used to accommodate copper busbars of different thicknesses. The protruding part between adjacent grooves 8 and the cross-sectional shape of the support rod 5 near the ground are arc-shaped. The arc shape can reduce the resistance when inserting the support rod 5 into the groove 8, making the insertion process smoother.

[0020] like Figure 1 , Figure 2 As shown, the lifting plate 6 is T-shaped. The protruding part of the lifting plate 6 is slidably connected to the end of the support rod 5 away from the punch 4. The two support rods 5 located on the same side of the base 1 have their ends away from the punch 4 recessed inward to form a sliding groove 9. The protruding part of the lifting plate 6 is slidably connected to the inner wall of the sliding groove 9. The setting of the sliding groove 9 limits the movement direction of the lifting plate 6, so that the lifting plate 6 can stably cooperate with the punching support table 3 to clamp and fix the copper busbar. The bottom surface of the sliding groove 9 is on the same plane as the upper surface of the punching support table 3, which avoids the lifting plate 6 from being stuck during the downward movement and thus being unable to effectively clamp the copper busbar.

[0021] like Figure 3 As shown, a buffer sheet 10 is bonded to the side of the lifting plate 6 near the punching support table 3. The buffer sheet 10 is made of rubber and has elastic deformation properties. When the lifting plate 6 moves downward to clamp the copper busbar, the buffer sheet 10 fits against the copper busbar. The setting of the buffer sheet 10 can reduce the wear caused to the copper busbar. At the same time, the elastic deformation properties of the buffer sheet 10 can allow the same groove 8 to accommodate more copper busbar thicknesses.

[0022] like Figure 3 As shown, both sides of the hydraulic cylinder 2 in the width direction are rotatably connected to rotating rods 11 for supporting the lifting plate 6. The rotating rods 11 are L-shaped. When the punching machine is not in use, the upper surface of the protruding part of the rotating rod 11 abuts against the lower surface of the lifting plate 6 to provide support for the lifting platform. The setting of the rotating rod 11 can fix the lifting plate 6 above the punching support platform 3, so that the operator will not be disturbed by the lifting plate 6 when placing the copper busbar. After the copper busbar is placed in the correct position, a pulling force is applied to the rotating rod 11 to make the rotating rod 11 rotate, so that the supporting force of the rotating rod 11 on the lifting plate 6 disappears, and the lifting plate 6 moves downward, causing the lower surface of the buffer plate 10 to abut against the upper surface of the copper busbar.

[0023] like Figure 1 , Figure 2 As shown, the distance between the clamping plate 7 and the rotating rod 11 is greater than the distance between the clamping plate 7 and the support rod 5 at one end perpendicular to the punching support platform 3. The clamping plate 7 is set on the side away from the punching support platform 3, which reduces the impact of the clamping plate 7 on the copper busbar models that the punching support platform 3 can originally place.

[0024] Working principle: A copper busbar punching machine. When in use, the operator places the copper busbar in the corresponding position of the punching support platform 3, rotates the rotating rod 11 to make the supporting force on the lifting plate 6 disappear, the lifting plate 6 slides downward and the buffer plate 10 abuts against the copper busbar. The operator applies a pushing force to the clamping plate 7 with his hand to make the clamping plate 7 rotate downward and squeeze the buffer plate 10 so that the groove 8 is engaged with the support rod 5, thereby clamping and fixing the copper busbar and then performing the punching operation on the copper busbar.

[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
