Description

Technical Field

[0001] This utility model relates to the field of copper busbar production technology, and more specifically, to an adjustable copper busbar bending device. Background Technology

[0002] Copper busbars, also known as copper busbars or copper busbars, are long conductors made of copper with a rectangular or chamfered (rounded) rectangular cross-section. Copper busbars are used in circuits to transmit current and connect electrical equipment. They are widely used in electrical equipment, especially in complete sets of power distribution equipment, particularly in electrical cabinets in substations. However, due to the special application of copper busbars, the manufactured copper busbars need to be bent to adapt to installation requirements.

[0003] The copper busbar bending die in the relevant technology can only bend copper busbars at the same angle at a time. If it is necessary to bend copper busbars at different angles, the bending die needs to be changed, which wastes production time. Utility Model Content

[0015] In some embodiments, the moving member is fixedly connected to the straight plate; the moving member is a semi-flexible, semi-rigid moving rod that can deform.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This application provides an adjustable copper busbar bending machine, which includes: a bending mechanism 10, including a lower die 11 for placing the copper busbar; and an upper die 12 disposed above the lower die 11 for impacting the lower die 11 and bending the copper busbar; the lower die 11 and the upper die 12 are formed by combining two adjustable straight plates 13. A lifting mechanism 20 is disposed above the upper die 12 for driving the upper die 12 to perform vertical linear motion. An adjusting mechanism 30 includes a pushing component 31 disposed above the upper die 12 and located at the output end of the lifting mechanism 20 for pushing the straight plates 13 to rotate and thus adjusting the angle of the upper die 12; limiting components 32 disposed on both sides of the straight plates 13 for limiting the running trajectory of the straight plates 13; and a lifting component 33 disposed below the lower die 11 for lifting the lower die 11 and straight plates 13 to change the angle.

[0025] Understandably, the lower die 11 and upper die 12 are mold components combined to process the copper busbar. For example, they can be concave-convex dies or guide dies, but are not limited to these. The upper die 12 and lower die 11 can have their angles adjusted without disassembly to process copper busbars with different bending angles. For example, they can be two independently set straight plates 13 connected together by hinges or other connecting parts, or a single straight plate 13 that is not completely cut, with a connecting sheet metal between the two cut sides, but are not limited to these. The lifting mechanism 20 is a component that drives the upper die 12 to rise and fall, thereby impacting the lower die 11 to stamp the copper busbar. For example, it can be a pneumatic lifting mechanism 20 or a hydraulic lifting mechanism 20, but is not limited to these. The adjusting mechanism 30 is a component that changes the angle between the two straight plates 13 by pushing the straight plates 13 to rotate, thus affecting the angle of the stamped copper busbar. For example, it can be a cam mechanism set between the two straight plates 13, or an inclined push rod mechanism, but is not limited to these. The pushing component 31 is the part that pushes the straight plate 13 to move. For example, it can be a push rod mechanism or a cam structure, but it is not limited to these. The limiting component 32 is the part that converts the linear motion of the straight plate 13 pushed by the pushing component 31 into rotational motion. For example, it can be a semi-circular plate 322 with a fixed arc track, or a crank-slider mechanism, but it is not limited to these.

[0026] As can be seen from the above, the four straight plates 13 are combined into an upper mold 12 and a lower mold 11 by hinges or other means in the equipment, so that the angles of the upper mold 12 and the lower mold 11 can be changed to adapt to diverse processing scenarios. An adjustment mechanism 30 is provided, which will automatically push the straight plate 13 to move, reducing the labor intensity of workers.

[0027] As is known, in some embodiments, please refer to Figure 1 or Figure 2 The upper mold 12 and the lower mold 11 are arranged opposite to each other; a rotating component 14 is provided between the two straight plates 13 to allow the two straight plates 13 to be rotatably connected.

[0028] Understandably, the rotating component 14 is a component that connects two straight plates 13, and the two straight plates 13 can rotate. For example, it can be a hinge, or a pivot installed between the two straight plates 13, but it is not limited to these.

[0029] With this configuration, the rotating component 14 positioned between the straight plates 13 allows the straight plates 13 to rotate and adjust their angle.

[0030] As is known, in some embodiments, please refer to Figure 1 The lifting mechanism 20 has a telescopic rod 21 connected to the push assembly 31, and a driver 22 connected to the telescopic rod 21.

[0031] Understandably, the telescopic rod 21 drives the upper mold 12 to impact the lower mold 11 by moving it up and down. For example, it can be a plastic telescopic rod 21 or a metal telescopic rod 21, but it is not limited to these. The driver 22 is a component that provides the power for the telescopic rod 21 to extend and retract. For example, it can be an electric motor or a pump, but it is not limited to these.

[0032] As is known, in some embodiments, please refer to Figure 1 and Figure 3 The pushing assembly 31 includes a driving member 311 disposed at the top of the telescopic rod 21; a moving member 312 disposed between the driving member 311 and the straight plate 13 for pushing the straight plate 13 to move; and a fixing member 313 disposed on the pushing assembly 31 and symmetrically distributed on both sides of the moving member 312 for pressing against the straight plate 13 and thus fixing the straight plate 13. The moving member 312 is fixedly connected to the straight plate 13; the moving member 312 is a deformable semi-flexible and semi-rigid moving rod. The limiting assembly 32 includes a plurality of cylindrical shafts 321 disposed on the side of the straight plate 13, and a semi-circular plate 322 fixedly connected to the driving member 311 to change the straight plate 13 from linear motion to rotation; the semi-circular plate 322 is provided with an arc-shaped groove 323 sleeved on the cylindrical shafts 321.

[0033] Understandably, the driving component 311 drives the movement of the moving component 312 and the fixing component 313. The moving component 312 rests against the straight plate 13. When the driving component 311 drives the moving component 312 to move the straight plate 13, the straight plate 13 moves linearly to both sides. At the same time, because the cylindrical shaft 3131 on the straight plate 13 moves along the arc groove 323 on the semicircular plate 322, the linear motion of the straight plate 13 is converted into a rotational motion around the connecting component. After the straight plate 13 rotates to a set angle, the fixing component 313 rests against the straight plate 13 to fix the straight plate 13. During the stamping process of the upper die 12, the wobbling of the straight plate 13 causes instability of the stamped copper busbar. For example, the driving component 311 can be an air pump, the moving component 312 is a telescopic rod 21 connected to the air pump, and the fixing component 313 is a push rod evenly distributed on the air pump and located on both sides of the moving component 312. The push rod can push against the straight plate 13 to fix the straight plate 13. Alternatively, the driving component 311 can be a hydraulic pump, the moving component 312 can be a cam mechanism driven by the hydraulic pump, the hydraulic pump drives the cam to rotate, thereby driving the straight plate 13 to rotate to change the angle between the two straight plates 13, and the fixing component 313 is a push rod to fix the straight plate 13, etc., but not limited to these.

[0034] With this configuration, the push component 31 pushes the straight plate 13 to rotate, thereby changing the angle between the straight plates 13. Then, the fixing part 313 holds the straight plate 13 in place, thus realizing the change of the angle of the upper mold 12 and improving production efficiency.

[0035] As is known, in some embodiments, please refer to Figure 2 The fixing groove 324 is used to fix the straight plate 13 and thus fix the angle of the upper mold 12.

[0036] Understandably, when the straight plate 13 is rotated to a suitable angle, a fixing groove 324 is needed to fix the straight plate 13. For example, it can be a square groove, in which a fixing block is directly inserted for fixing, or it can be a round groove, in which threads are set on the cylindrical shaft 321, and then a nut is screwed in to fix the upper mold 12, etc., but it is not limited to these methods.

[0037] With this configuration, the fixing groove 324 horizontally fixes the straight plate 13 to prevent it from continuing to slide.

[0038] As is known, in some embodiments, please refer to Figure 2 The lifting components 33 are evenly distributed on both sides of the straight plate 13 of the lower mold 11.

[0039] Understandably, the lifting assembly 33 is distributed on the lower mold 11. The lifting assembly 33 is set perpendicularly to the straight plate 13 of the lower mold 11 and is a component used to lift the lower mold 11 and thus change the angle of the lower mold 11. For example, it can be a pneumatic lifting assembly or an electric lifting assembly, but it is not limited to these.

[0040] With this configuration, the lower die 11 and the upper die 12 maintain the same angle, improving stamping accuracy.

[0041] As can be seen from the above, after adjusting the upper and lower molds to the required angles, the upper mold is fixed with fasteners and restrictors, the copper busbar is placed on the lower mold, and the lifting mechanism is activated at the same time. The lifting mechanism drives the upper mold to impact the copper busbar downwards.

[0042] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
