DETAILED DESCRIPTION

[0023] The following will be combined with the attached embodiment of the present utility model Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] As shown in the figure, a copper busbar bending device includes a frame 1, a forming mechanism is arranged on the frame 1, and a feeding mechanism is also arranged on the frame 1. The forming mechanism includes two static molds 21 fixedly arranged on the frame 1 and symmetrically arranged, and two movable molds 22 slidably arranged on the frame 1 and respectively matched with the two static molds 21, and a positioning gap 25 is formed between the two static molds 21. The feeding mechanism includes a positioning plate 31 arranged above one static mold 21, a guide plate 32 arranged above the other static mold 21, a mounting plate 33 arranged on the frame 1 away from the guide plate, and a placing plate 34 whose two ends are respectively fixedly connected to the upper end of the guide plate 32 and the mounting plate 33, and a positioning gap 25 is formed between the positioning plate 31 and the guide plate 32. 25 is aligned with a loading gap 35, the width of the positioning gap 25 and the loading gap 35 match the thickness of the copper busbar, the mounting plate 33 is provided with a ejector rod 36 with its end pointing to the positioning plate 31, the ejector rod 36 is sleeved with a ejector spring 37 that abuts against the mounting plate 33, the positioning plate 31 is provided with a loading cylinder 38 with an output shaft facing downward, the output shaft of the loading cylinder 38 is connected with a loading ejector pin 39 that can pass through the loading gap 35, the frame 1 is provided with a feeding port 11 located below the positioning gap 25, the frame 1 is provided with a supporting plate 40 that shields the feeding port 11 and is connected to the output shaft of a driving cylinder 41 arranged on the frame 1, and the upper surface of the supporting plate 40 is flush with the table top of the frame 1.

[0025] Specifically, the movable mold 22 is slidably arranged on the frame 1: the static mold 21 is fixedly connected to the frame 1 by bolts and a limiting convex strip 211 is fixedly arranged on the side end face of the static mold 21; a limiting slide groove 221 matching the limiting convex strip 211 is opened on the side end face of the movable mold 22; the movable mold 22 is placed on the frame 1 and is transmission-connected to the hydraulic cylinder 23 so that the limiting convex strip 211 is kept in the limiting slide groove 221.

[0026] In the above embodiment, the copper busbars to be bent are arranged on the placing plate 34 and located between the positioning plate 31 and the ejecting rod 36. The ejecting rod 36 slides toward the copper busbars under the action of the ejecting spring 37 and pushes the copper busbars, so that the front end of the copper busbar is tightly against the positioning plate 31 and aligned with the feeding gap 35. Then the feeding cylinder 38 drives the feeding ejector pin 39 to move downward and push the front end of the copper busbar, driving the copper busbar to slide downward through the feeding gap 35 and then penetrate into the positioning gap 25 and be built into the supporting plate 40 to realize the feeding of the copper busbar. After the feeding is completed, the feeding ejector pin 39 moves upward to exit the feeding gap 35. At the same time, the next copper busbar is tightly against the positioning plate 31 and aligned with the feeding gap 35 under the push of the ejecting rod 36. Then the hydraulic cylinder 23 drives the movable mold 22 to slide and cooperate with the static mold 22 to ... The mold 21 bends the copper busbar into shape, and then drives the cylinder 41 to drive the supporting plate 40 to slide outward and leave the shielding position of the unloading port 11, so that the positioning gap 25 is connected with the unloading port 11, and the formed copper busbar leaves the positioning gap 25 when the supporting port of the supporting plate 40 is lost and falls through the unloading port 11, realizing the unloading of the copper busbar. After the formed copper busbar is unloaded, the supporting plate 40 is reset to support the next copper busbar loaded into the positioning gap 25. Through the above structure and method, during the operation of bending and forming the copper busbar, it is only necessary to manually arrange the copper busbar on the placing plate 34, which reduces the degree of manual participation, reduces the safety hazards in the production process, saves manpower, and improves the production efficiency by automatically and continuously performing the operations of loading, forming and unloading.

[0027] Preferably, the movable mold 22 is fixedly connected with a guide rod 222 which is parallel to the limiting convex strip 211 and passes through the static mold 21. The guide rod 222 is sleeved with a reset spring 24 located between the static mold 21 and the movable mold 22. During the sliding of the movable mold 22, the guide rod 222 slides in the static mold 21 to provide further guiding effect for the movable mold 22, thereby ensuring the stability of the movable mold 22 when sliding and ensuring the quality of the bending forming. In addition, the reset spring 24 ensures that the movable mold 22 slides into place when the movable mold 22 is reset, thereby ensuring that the movable mold 22 does not interfere with the feeding of the copper busbar.

[0028] Preferably, a baffle plate 42 is provided on each side of the placing plate 34, and the two ends of the baffle plate 42 are respectively connected to the positioning plate 31 and the mounting plate 33, and the spacing between the two baffles matches the length of the copper busbar. When the copper busbar is arranged and placed on the placing plate 34, the baffle plates contact the two ends of the copper busbar, so that the copper busbar can be more conveniently and neatly arranged on the placing plate 34, thereby ensuring the quality of bending and forming.

[0029] Preferably, the baffle plate 42 is in the shape of a U-shaped plate and an adjusting slot 421 is provided on the vertical portion of the baffle plate 42. The positioning plate 31 and the mounting plate 33 are fixedly connected with an adjusting screw 43 that passes through the adjusting slot 421. The adjusting screw 43 is threaded with an adjusting nut 44 that is tightly against the baffle plate 42. After loosening the adjusting nut 44, the baffle plate 42 can slide horizontally on the positioning plate 31 and the mounting plate 33 through the cooperation of the adjusting screw 43 and the adjusting slot 421 to adjust the spacing between the two baffle plates 42 to adapt to the bending operation of copper busbars of different lengths. Moreover, by adjusting the distance of the baffle plate 42 relative to the loading plate 34, the center of the copper busbar can be not located on the center line of the loading plate 34 after being placed on the loading plate 34, so that the two ends of the formed copper busbar can have different bending lengths to meet different needs and have better applicability.

[0030] Preferably, an anti-skid pad layer 311 opposite to the ejection rod 36 is provided on the surface of the positioning plate 31 facing the ejection rod 36, and the copper busbar placed on the front end of the loading plate 34 is tightly against the anti-skid pad layer 311. When the anti-skid pad layer 311 increases the friction force, the front end of the copper busbar is more stably maintained above the loading gap 35 and aligned with the loading gap 35, thereby preventing the copper busbar from sliding downward into the positioning gap 25 due to its own weight and causing interference to the forming operation.

[0031] Preferably, the frame 1 is provided with a feeding cylinder 51 with an output shaft facing the feeding cylinder 51, and the output shaft of the feeding cylinder 51 is connected to a feeding ejector pin 52 located above the moving path of the movable mold 22, so that the feeding ejector pin 52 is aligned with the bent portion at one end of the formed copper busbar. After the supporting plate 40 leaves the shielding position for the feeding port 11, the feeding cylinder 51 drives the feeding ejector pin 52 to move downward to ensure that the formed copper busbar can leave the positioning gap 25 and be discharged through the line of sight of the feeding port 11.

[0032] Preferably, the frame 1 is provided with a discharge inclined plate 12 located below the discharge port 11, and a receiving box 6 is provided below the discharge inclined plate 12. After the formed copper busbar discharged through the discharge port 11 falls onto the discharge inclined plate 12, it slides down along the discharge inclined plate 12 and falls into the receiving box 6, which is convenient for collecting the formed copper busbar.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
