Description

Technical Field

[0001] This invention belongs to the field of copper busbar production and processing technology, specifically relating to an integrated bending and punching device for copper busbar processing. Background Technology

[0002] A copper busbar, also known as a copper busbar or copper busbar, is a long conductor made of copper with a rectangular or chamfered (rounded) rectangular cross-section (rounded copper busbars are now generally used to avoid point discharge). It serves to transmit current and connect electrical equipment in a circuit.

[0003] During the processing of copper busbars, holes need to be punched at both ends for easy connection in circuits. After punching, the busbars need to be bent. In daily life, most copper busbar processing involves punching and bending on separate punching and bending machines. This means that after punching the copper busbar on the punching machine, it needs to be transferred to the bending machine for bending, which increases unnecessary time costs and leads to low processing efficiency. When bending the copper busbar, it is placed between the bend and the bending base, and the bending head compresses the copper busbar to cause deformation. However, for most copper busbar bending machines, different angles of bending require bending bases with different angles. When different angles of bending are required, the bending base needs to be disassembled and replaced. This process of disassembling and replacing the bending base also affects work efficiency and urgently needs optimization. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated bending and punching device for copper busbar processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

An electric actuator is fixed to one end of the base. A hydraulic cylinder is fixed to the output end of the electric actuator. A geared disc is rotatably connected to the output end of the hydraulic cylinder. A rack meshes on the geared disc. The rack is fixedly connected to the base. A mounting plate is fixed to the other side of the geared disc. A punching head for punching copper busbars is connected to the other side of the mounting plate. A bending head for bending copper busbars is also connected to the other side of the mounting plate. A punching seat that mates with the punching head and a bending seat that mates with the bending head are also provided on the processing table.

[0007] Preferably, the bending seat includes two bending plates and a rotating shaft. The rotating shaft is vertically fixed on the end face of the processing table. The ends of the two bending plates are hinged to the rotating shaft. The included angle between the two bending plates corresponds to the bending angle of the copper busbar. An angle adjustment component for adjusting the included angle between the two bending plates is also provided on the processing table.

[0008] Preferably, the included angle adjustment component includes:

[0009] Two connecting blocks are fixed to the bottom ends of two bending plates respectively. A movable groove is provided through the processing table. The movable groove is an arc-shaped groove with the rotating shaft as the center. The connecting blocks are set in the movable groove.

[0010] Two rotating blocks are fixed to the bottom of two connecting blocks respectively, and through holes are provided on both rotating blocks;

[0011] A connecting rod, which passes through two through holes, and a connecting plate is fixed in the middle of the connecting rod, with a threaded hole through the connecting plate;

[0012] A threaded rod, which is disposed through a threaded hole, is used to drive the connecting plate.

[0013] Preferably, the electric actuator, hydraulic cylinder, punching seat, and bending seat are all configured in two sets, and the two sets of electric actuator, hydraulic cylinder, punching seat, and bending seat are symmetrically arranged about the center of the processing table.

[0014] Preferably, a groove is formed along the length of the top end face of the bending plate, and a slider is movably disposed in the groove. A support frame is also provided above the bending plate. The support frame includes two support rods, which are rotatably connected at the middle. The sliders are rotatably connected to the bottom of the support rods. An electromagnet is also fixed at the bottom of the groove. The sliders are made of magnetic metal.

[0015] Preferably, the mounting plate is a circular plate, and two mounting blocks are symmetrically arranged on the mounting plate. The punching head and the bending head can be detachably mounted on the two mounting blocks.

[0016] Preferably, the mounting block has an insertion hole, and the punch head and the bending head are fixed with insertion blocks, and the punch head and the bending head are mounted on the mounting block through the insertion blocks.

[0017] Preferably, two abutment blocks are also fixed on the bending seat, and the two abutment blocks are respectively fixed on the side wall of the two bending plates that are far apart from each other.

[0018] Preferably, the abutment is made of non-slip rubber.

[0019] Preferably, the mounting block and the mounting plate are rotatably connected, a counterweight is fixed at the bottom of the mounting block, the insertion hole is inclined and the insertion hole port is inclined upward.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. This invention integrates the two processing functions of punching and bending copper busbars into one machine by setting a punching head and punching seat on the processing table of the equipment, and a bending head and bending seat for bending copper busbars. This eliminates the transfer step in the prior art where the copper busbar is punched on the punching machine and then transferred to the bending machine, thereby reducing time costs and improving processing efficiency.

[0022] 2. This invention provides a bending seat composed of two bending plates with an adjustable included angle. The included angle between the two bending plates is adjusted by rotating a threaded rod, thereby achieving the effect of adjusting the angle of the bending seat. This eliminates the need for disassembling and replacing the bending seat in the prior art, optimizes the operation, and further improves the efficiency of bending copper busbars.

[0023] 3. This invention, by setting support frames on the bending plates on both sides, generates an interaction force between the two bending plates connected by support rods on both sides when the copper busbar is bent. Under the action of this interaction force, the bending plates can remain stable during the bending process of the copper busbar, thereby ensuring the bending effect of the integrated equipment on the copper busbar.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] Example 1:

[0041] like Figure 1-4As shown, a bending and punching integrated equipment for copper busbar processing includes a processing table 1, a base 11 fixed on the upper surface of the processing table 1, an electric push rod 12 fixed at one end of the base 11, a hydraulic cylinder 13 fixed at the output end of the electric push rod 12, a gear plate 14 rotatably connected to the output end of the hydraulic cylinder 13, a rack 15 meshing on the gear plate 14, the rack 15 being fixedly connected to the base 11, a mounting plate 2 fixed on the other side of the gear plate 14, a punching head 3 for punching copper busbars connected to the other side of the mounting plate 2, a bending head 4 for bending copper busbars connected to the other side of the mounting plate 2, a punching seat 5 cooperating with the punching head 3 on the processing table 1, and a bending seat 6 cooperating with the bending head 4 on the processing table 1.

[0042] It should be noted that: such as Figure 6 , 7 As shown, when the equipment is in its initial state, the output end of the hydraulic cylinder 13 is aligned with the middle of the bending seat 6, and the bending head 4 is located at the lower end of the mounting plate 2 and directly opposite the middle of the bending seat 6.

[0043] When it is necessary to punch a copper busbar, first place the copper busbar inside the punching seat 5, then start the electric actuator 12 to push the hydraulic cylinder 13 to the position directly opposite the punching seat 5. At this time, under the combined action of the gear plate 14 and the rack 15, the mounting plate 2 rotates. At this time, the punching head 3 is located at the lower end of the mounting plate 2 and cooperates with the punching seat 5. Then start the hydraulic cylinder 13. Under the action of the hydraulic cylinder 13, the punching head 3 outputs towards the copper busbar to perform punching processing on the copper busbar.

[0044] After the copper busbar is punched, the output end of the hydraulic cylinder 13 returns to the initial position. At this time, the electric actuator 12 is driven to drive the hydraulic cylinder 13 back to the initial position. At this time, the bending head 4 is located at the lower end of the mounting plate 2 and is directly opposite the middle of the bending seat 6. The punched copper busbar is then placed between the bending seat 6 and the bending head 4. Finally, the hydraulic cylinder 13 is started to make the bending head 4 output towards the copper busbar to perform bending processing on the copper busbar.

[0045] The above configuration, by setting a punching head 3 and a punching seat 5 for punching copper busbars, and a bending head 4 and a bending seat 6 for bending copper busbars on the processing table 1 of the equipment, and simultaneously, when the electric push rod 12 is activated, the punching head 3 and the bending head 4 are switched at the corresponding positions through the cooperation of the gear plate 14 and the rack 15, so as to realize the punching and bending processing of copper busbars respectively. The two processing functions of copper busbar punching and bending are integrated into one machine, eliminating the transfer step of the copper busbar being punched on the punching machine and then transferred to the bending machine in the prior art, thereby reducing time costs and improving processing efficiency.

[0046] It is worth noting that when the hydraulic cylinder 13 is in the initial position, the gear plate 14 is located at the beginning of the rack 15. When the punching head 3 is located at the lower end of the mounting plate 2 and cooperates with the punching seat 5, the gear plate 14 is located at the end of the rack 15 and disengaged from the rack 15. At this time, the mounting plate 2 will no longer rotate under the pushing action of the electric actuator 12, so that the punching head 3 will remain in a state of facing the punching seat 5.

[0047] The advantages of the above setup are: under the subsequent push of the electric actuator 12, the punch head 3 can maintain its engagement with the punch seat 5, thereby enabling the punch head 3 to punch holes at different positions on the copper busbar without adjusting the position of the copper busbar, thus improving the functionality and ease of operation of the integrated equipment and ensuring work efficiency.

[0048] Example 2:

[0049] The difference between this embodiment and Embodiment 1 is that, in order to enable the bending seat 6 to bend copper busbars at different angles, such as... Figure 1 , 3 As shown in Figure 5, the bending seat 6 includes two bending plates 61 and a rotating shaft 62. The rotating shaft 62 is vertically fixed on the end face of the processing table 1. The ends of the two bending plates 61 are hinged to the rotating shaft 62. The included angle between the two bending plates 61 corresponds to the bending angle of the copper busbar.

[0050] Furthermore, in order to facilitate the adjustment of the included angle between the two bending plates 61, an included angle adjustment component 7 is also provided on the processing table 1 for adjusting the included angle between the two bending plates 61.

[0051] The included angle adjustment assembly 7 includes: two connecting blocks 71, two rotating blocks 72, a connecting rod 73, and a threaded rod 74.

[0052] Two connecting blocks 71 are fixed to the bottom ends of two bending plates 61 respectively. A movable groove 16 is provided through the processing table 1. The movable groove 16 is an arc-shaped groove with the rotating shaft 62 as the center. The connecting blocks 71 are set in the movable groove 16. Two rotating blocks 72 are fixed to the bottom of the two connecting blocks 71 respectively. A through hole 721 is provided through the two rotating blocks 72. The connecting rod 73 passes through the two through holes 721. A connecting plate 731 is fixed in the middle of the connecting rod 73. A threaded hole 732 is provided through the connecting plate 731. A threaded rod 74 is provided through the threaded hole 732. The threaded rod 74 is used to drive the connecting plate 731.

[0053] When the copper busbar needs to be bent at different angles, by rotating the threaded rod 74, the connecting plate 731, which is threadedly connected to the threaded rod 74, will move along the threaded rod 74. At the same time, the connecting rod 73 also moves with the connecting plate 731, thereby driving the two connecting blocks 71 located in the movable groove 16, thereby achieving the effect of adjusting the included angle between the two bending plates 61.

[0054] When the threaded rod 74 rotates clockwise, the two connecting blocks 71 move toward both ends of the movable groove 16, at which time the included angle of the bending seat 6 increases; when the threaded rod 74 rotates counterclockwise, the two connecting blocks 71 move toward the middle of the movable groove 16, at which time the included angle of the bending seat 6 decreases.

[0055] The above configuration, by setting up a bending seat 6 composed of two bending plates 61 with adjustable included angle, and then adjusting the included angle between the two bending plates 61 by rotating the threaded rod 74, achieves the effect of adjusting the angle of the bending seat 6. This eliminates the steps of disassembling and replacing the bending seat 6 in the prior art, optimizes the operation, and further improves the efficiency of bending copper busbars.

[0056] Example 3:

[0057] The difference between this embodiment and Embodiment 2 is that, as Figure 1 , 3 As shown in Figure 5, in order to further improve the efficiency of punching and bending copper plates by the integrated equipment, the electric push rod 12, hydraulic cylinder 13, punching seat 5 and bending seat 6 are all set in two groups, and the two groups of electric push rod 12, hydraulic cylinder 13, punching seat 5 and bending seat 6 are symmetrically arranged about the center of the processing table 1. At the same time, the worm gear 75 is coaxially fixed on the threaded rod 74, and the drive motor 76 is also fixed at the bottom of the processing table 1. The worm 77 that meshes with the worm gear 75 is fixed at the output end of the drive motor 76.

[0058] With the above settings, two copper busbars can be punched and bent simultaneously, thereby further improving the equipment's processing efficiency for copper busbars.

[0059] Furthermore, such as Figure 8 As shown, a groove 63 is provided along the length of the top end face of the bending plate 61. A slider 64 is movably mounted in the groove 63. A support frame 65 is also provided above the bending plate 61. The support frame 65 includes two support rods 651, which are rotatably connected in the middle. The sliders 64 are rotatably connected to the bottom of the support rods 651. An electromagnet 66 is also fixed at the bottom of the groove 63. The sliders 64 are made of magnetic iron.

[0060] In the above configuration, when bending the copper busbar, the angle between the two bending plates 61 must first be adjusted. After the angle adjustment is completed, the electromagnet 66 at the bottom of the slide 63 is activated, causing the electromagnet 66 to attract the slider 64, thereby fixing the two support rods 651. At this time, during the bending process of the copper busbar, an interaction force will be generated between the two bending plates 61 connected by the support rods 651 on both sides of the bending seat 6. Under the action of the interaction force, the bending plates 61 can be kept in a stable state during the bending process of the copper busbar, thus ensuring the bending effect of the integrated equipment on the copper busbar.

[0061] like Figure 1 , 2 As shown, the mounting plate 2 is a circular plate, and two mounting blocks 21 are symmetrically arranged on the mounting plate 2. The punching head 3 and the bending head 4 can be detachably mounted on the two mounting blocks 21. The mounting blocks 21 are provided with insertion holes 211. Insertion blocks 212 are fixed on the punching head 3 and the bending head 4. The punching head 3 and the bending head 4 are mounted on the mounting blocks 21 through the insertion blocks 212.

[0062] Furthermore, the mounting block 21 is rotatably connected to the mounting plate 2, and a counterweight block 22 is fixed at the bottom of the mounting block 21. The insertion hole 211 is set at an angle, with the port of the insertion hole 211 tilted upwards.

[0063] The above configuration, by detachably setting the punching head 3 and bending head 4, facilitates the replacement of punching heads 3 and bending heads 4 of different specifications, thereby making the integrated equipment suitable for punching and bending copper busbars of different specifications, further demonstrating the functionality of the integrated equipment; at the same time, the upward tilt of the insertion hole 211 port can prevent the punching head 3 or bending head 4 from detaching from the mounting block during processing, thereby ensuring the normal processing of copper busbars by the equipment; wherein the mounting block 21 is rotatably connected to the mounting plate 2 and the bottom end of the mounting block 21 is fixed with a counterweight block 22, through the above cooperation, the insertion hole 211 port can always be in an upward position.

[0064] like Figure 4 , 6 As shown, two abutment blocks 67 are also fixed on the bending seat 6. The two abutment blocks 67 are respectively fixed on the side wall of the two bending plates 61 that are far apart from each other, and the material of the abutment blocks 67 is anti-slip rubber.

[0065] With the above settings, when the equipment punches the copper busbar, the included angle between the two bending plates 61 can be adjusted to 180°. At this time, the abutment block 67 can abut against the copper busbar, thereby improving the stability of the copper busbar during the punching process and thus improving the punching effect of the equipment on the copper busbar. At the same time, the abutment block 67 made of anti-slip rubber material can further improve the abutment effect on the copper busbar.

[0066] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
