Description

Technical Field

[0001] This utility model relates to the field of busbar processing technology, and in particular to a busbar punching and flattening tool. Background Technology

[0002] like Figure 3 A three-dimensional structural diagram of the busbar is shown. Generally, the busbar 1 is bent into various folded structures to different degrees according to the wiring method, and connection holes 10 are processed at both ends by punching. The punching method has the advantages of high efficiency and no burrs on the inner wall of the connection hole 10 after punching. However, during the punching process, the busbar 1 is recessed from one side to the other. When the concave structure is connected by bolts, it will cause the contact area between the wire connector and the busbar 1 to be reduced, or a poor contact structure to be formed. When energized, serious heat generation will occur at the connection point. Secondly, the punching process will form sharp edges on the peripheral edges of the connection hole 10, and these sharp edges will affect the electrical connection effect. Utility Model Content

[0003] This utility model provides a busbar punching and flattening tool to overcome the shortcomings of the prior art and solve the adverse effects of defects in the busbar forming process on the busbar electrical connection, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A busbar punching and flattening tool includes a long strip-shaped base plate. A first elongated hole and a pair of second elongated holes are respectively formed at both ends of the base plate, parallel to its length. The second elongated holes are located on either side of the first elongated holes. Upper plates are respectively provided at the lower ends of the base plate. A pair of fixing screws are threaded onto the upper plates, with the lower ends of the screw caps abutting against the upper side of the base plate. A pull rod is coaxially threaded through the upper plates, and a lower plate is coaxially threaded onto the lower end of the pull rod. A concave seat is fitted onto the pull rod, and limit screws are threaded to both ends of the concave seat. A top of the base plate is provided with… There is an upper pull plate, with a third elongated hole at both ends parallel to its length direction. The pull rod passes through the third elongated hole. Side strips extend upward from both sides of the upper pull plate, with end transverse holes at both ends parallel to its length direction. The rod part of the limit screw passes through the end transverse hole. The concave seat is located on the upper side of the upper pull plate. End plates are bent at both ends of the upper pull plate, and guide screws are threaded onto the end plates. Vertical plates are bent upward at both ends of the bottom plate, with guide holes set vertically on the vertical plates, and guide screws pass through the guide holes.

[0005] Furthermore, a skirt is formed by extending the base plate upwards, and the skirt is located between the vertical plates.

[0006] Furthermore, a lead screw is rotatably mounted on the base plate. The upper end of the lead screw is fixed with a head, and the lower end of the lead screw is connected to a lower nut via a thread. The lower nut is located below the base plate, and a threaded sleeve is connected to the lead screw via a thread. The lower end of the threaded sleeve is welded to the upper pull plate.

[0007] Furthermore, a U-shaped groove is formed on the inner side of the concave seat, and an insert rod is formed in the U-shaped groove. The upper end of the pull rod passes through the U-shaped groove, and the insert rod is inserted into the upper end of the pull rod.

[0008] Furthermore, a conical ring with a conical outer perimeter is coaxially formed on the lower side of the upper plate, with the lower end of the conical ring being the smaller end.

[0009] Furthermore, an upper convex conical ring is coaxially formed on the upper side of the lower plate. The outer periphery of the upper convex conical ring has a conical structure, and the upper end of the outer periphery of the upper convex conical ring is the small end.

[0010] The advantages of the above technical solution are: This invention uses an upper and lower plate to act simultaneously on both sides of the busbar connection hole. When the upper and lower plates apply pressure, the busbar connection hole can be made flat, thereby reducing the adverse effects on the busbar electrical connection caused by the punching process.

[0011] Secondly, in order to facilitate the insertion of the pull rod into the connecting hole, the pull rod is detachably connected to the upper pull plate, and the pull rod is locked to the upper pull plate by a pair of concave seats. In this way, the upper pull plate and the bottom plate can be moved away from each other by rotating the screw, and then the upper and lower plates can be used to flatten and straighten the connecting hole.

[0012] Finally, in order to eliminate the sharp edges on the inner wall of the connecting hole, a tapered ring was installed on the upper plate and an upper convex tapered ring was installed on the lower plate. Attached Figure Description

[0016] Figure 3 A three-dimensional structural diagram of the busbar is shown. Detailed Implementation

[0017] like Figures 1-3As shown, a busbar punching and flattening tool includes a long strip-shaped base plate 2. A first elongated hole 21 and a pair of second elongated holes 20 are respectively formed at both ends of the base plate 2, parallel to its length direction. The second elongated holes 20 are located on both sides of the first elongated holes 21. Upper plates 24 are respectively provided at the lower ends of the base plate 2. A pair of fixing screws are threaded onto the upper plates 24, with the lower ends of the screw caps abutting against the upper side of the base plate 2. A pull rod 22 is coaxially threaded through the upper plates 24. A lower plate 23 is coaxially threaded onto the lower end of the pull rod 22. A conical ring 240 with a tapered outer circumference is coaxially formed on the lower side of the upper plates 24, with the lower end of the conical ring 240 being the smaller end. An upper convex conical ring 230 with a tapered outer circumference is coaxially formed on the upper side of the lower plate 23, with the upper end of the upper convex conical ring 230 being the smaller end. A concave seat 33 is fitted onto the pull rod 22. Limit screws 32 are threaded to both ends of the concave seat 33. An upper pull plate 27 is located above the base plate 2. A third elongated hole 28 is formed at both ends of the upper pull plate 27, parallel to its length direction. The pull rod 22 passes through the third elongated hole 28. Side strips 29 extend upwards from both sides of the upper pull plate 27. End transverse holes 30 are formed at both ends of the side strips 29, parallel to their length direction. The rod portion of the limit screw 32 passes through the end transverse hole 30. The concave seat 33 is located above the upper pull plate 27. A U-shaped groove 34 is formed on the inner side of the 33, and an insert rod 35 is formed in the U-shaped groove 34. The upper end of the pull rod 22 passes through the U-shaped groove 34, and the insert rod 35 is inserted into the upper end of the pull rod 22. The two ends of the upper pull plate 27 are bent into end plates 31, and guide screws 26 are threaded onto the end plates 31. The two ends of the bottom plate 2 are bent upward to form vertical plates 25. The vertical plates 25 are provided with vertically arranged guide holes 250, and the guide screws 26 pass through the guide holes 250. The bottom plate 2 extends upward to form a skirt, which is located between the vertical plates 25.

[0018] A lead screw 37 is rotatably mounted on the base plate 2. An end 38 is fixed at the upper end of the lead screw 37, and a lower nut 39 is threadedly connected to the lower end of the lead screw 37. The lower nut 39 is located below the base plate 2. A threaded sleeve 36 is threadedly connected to the lead screw 37, and the lower end of the threaded sleeve 36 is welded to the upper pull plate 27.

[0019] In this embodiment, the operator inserts the pull rod 22 into the connecting hole 10 of the busbar 1, ensuring that the upper end of the lower plate 23 abuts against the protruding end of the connecting hole 10. Then, the operator inserts the pull rod 22 into the upper plate 24 and the third elongated hole 28. Next, the operator moves the concave seat 33 inward so that the upper end of the pull rod 22 passes through the U-shaped groove 34, and the insert rod 35 is inserted into the upper end of the pull rod 22. Then, the operator rotates the lead screw 37 through the end 38. When the lead screw 37 rotates, it drives the upper pull plate 27 upward. During the movement, the lower wall of the upper plate 24 abuts against the upper side of the busbar 1, and the upper end of the lower plate 23 abuts against the protruding end of the connecting hole 10. When the lead screw 37 rotates, the lower plate 23 applies pressure to the protruding part to make it gradually flat. The lower wall of the upper plate 24 abuts against the recess of the connecting hole 10, thus avoiding excessive pressure from the lower plate 23, which would cause the upper side of the busbar 1 to bulge upward again. At the same time, the inner circumferential edge of the connecting hole 10 is deformed into a conical structure by the conical ring 240 and the upper convex conical ring 230 respectively.

[0020] In practical applications, the position of the upper plate 24 can be adjusted according to the hole spacing of the connecting holes 10. During adjustment, first loosen the fixing screws, then adjust the position of the upper plate 24, and finally fix it with the fixing screws. Then, perform a flattening operation at the connecting holes 10.

Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
