[0002] A busbar is a conductor system used to efficiently transmit and distribute electrical energy. It has the following features: centralized power transmission: the busbar can connect multiple power lines in a centralized manner, improving power transmission efficiency and reducing energy loss; large current carrying capacity: copper or aluminum busbars can carry large currents of 1000A-5000A, and are suitable for high-power industrial applications, data centers and renewable energy systems; optimized distribution system: in distribution boxes or electrical cabinets, busbars can simplify wiring, improve installation efficiency, and make electrical panels more beautiful and safer; prevent accidental contact with live parts: insulated busbars can reduce the risk of electric shock and are suitable for non-professional operations such as residential distribution boxes; reduce mechanical damage: compared with traditional cables, the busbar structure is more stable and not easily damaged by vibration or external force. It is widely used in power distribution, industrial equipment, data centers, electric vehicles and other fields.

[0003] In the prior art, the busbar is a flat metal sheet structure, which needs to be punched on the surface of the metal sheet or grooved at the edge to facilitate the connection of the line. In the prior art, the metal sheet needs to be fixed on the clamping part and then punched through the stamping structure, resulting in low punching efficiency, low mechanization level and high labor input. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a busbar punching device with a high degree of automation.

[0005] The technical solution adopted to solve the above technical problems is: a busbar punching equipment, including a punching processing platform that provides a punching place, a unloading hole is opened through one side of the upper surface of the punching processing platform for unloading the busbar after punching, and a metal bar conveying structure is provided on both sides of the unloading hole on the upper surface of the punching processing platform.

[0006] Through the above technical solution, the punching processing platform provides a platform for metal bar transmission, punching and unloading. The unloading hole allows the metal bars to slide into the collection frame inside the punching processing platform when they form a bus after punching, which is convenient for collection. The metal bar conveying structure can convey the unpunched metal bars and the punched bus to the designated location.

[0007] The upper surface of the punching processing platform is provided with two symmetrically arranged limiting guide platforms for pressing down the metal strips at a position above the metal strip conveying structure and the discharge hole.

[0008] Through the above technical solution, the limiting guide table can press the metal strip in a straight line during the transmission process to prevent the metal strip from deviating from the transmission track or tilting during the transmission process, which affects the stamping yield.

[0009] An automatic feeding structure is provided on the upper surface of the punching processing platform away from the discharge hole and located at the end surface of the limiting guide platform. A punching structure for metal strip punching is installed on the side of the automatic feeding structure close to the discharge hole.

[0010] Through the above technical solution, the automatic feeding structure can discharge the stacked metal bars one by one and push them to the lower position of the punching structure, so as to facilitate accurate punching of them by the punching structure.

[0011] Furthermore, the metal bar conveying structure includes several support shafts rotatably connected through a support plate and two conduction slots opened on the surface of the punching processing platform. Conveying teeth are fixedly connected through both ends of the support shafts. The conveying teeth pass through the corresponding conduction slots. The outer side of the conveying teeth is wrapped with rubber material. Several transmission pulleys are fixedly connected through the middle positions of the support shafts.

[0012] Through the above technical solution, the transmission teeth can pass through the conduction slots, and the outer sides of the transmission teeth and the pressure guide wheel are wrapped with rubber material, so that the friction and extrusion transmission force between them and the metal strips or buses are greater and more stable, so that the metal strips or buses can run at a uniform and stable speed. At the same time, the rubber material has good softness and will not cause damage to the metal strips or buses.

[0013] Furthermore, several of the transmission pulleys are connected by a transmission belt, and one end of the support shaft away from the automatic feeding structure passes through the punching processing platform. A power motor is provided on one side of the punching processing platform, and the driving end of the power motor and the support shaft passing through the side wall of the punching processing platform are both fixedly connected with a power pulley, and a power belt is provided between the two power pulleys.

[0014] Through the above technical solution, the support shaft can fix and support the transmission teeth through the support plate, and the transmission belt can transmit power so that several transmission teeth rotate at the same speed and in the same direction at the same time, thereby generating a driving force on the metal bar or bus, so that the bus and metal bar are transmitted, and the power motor serves as the power source, and the power of the power motor is transmitted through the power pulley and the power belt.

[0015] Furthermore, two control doors for removing materials are provided on one side of the punching processing platform, and a number of evenly distributed pressing guide wheels are rotatably connected to the lower surface of the limiting guide platform. The outer wall of the pressing guide wheel is wrapped with rubber material, and a number of evenly distributed punching discharge holes are penetrated through the upper surface of the punching processing platform below the punching structure.

[0016] Through the above technical solution, the control door can be used to remove the waste generated by punching and the bus after punching. The pressing guide wheel can press the metal strips and the bus down so that they will not leave the limit guide table during transportation, and the pressing guide wheel will cause rolling friction with the metal strips and the bus without sliding friction.

[0017] Furthermore, the automatic feeding structure includes a material storage box fixedly connected to the upper surface of the punching processing platform, a sliding slot is provided at the bottom of the material storage box close to the punching structure, two symmetrically arranged backflow preventers are provided at the bottom positions on both sides of the material storage box, and a top sealing cover is provided on the top of the material storage box.

[0018] Through the above technical solution, the storage box can stack and store metal bars to be punched, and the punching discharge holes can allow the metal waste generated by punching to leak into the punching processing platform for centralized collection. The anti-backflow device prevents the conveying teeth from slipping when squeezing and conveying the metal bars at the bottom of the storage box and causing them to slide out.

[0019] Furthermore, several evenly distributed clamping springs are fixedly connected to the lower surface of the top sealing cover, and several of the clamping springs are fixedly connected to a clamping plate at one end away from the top sealing cover. The top positions on both sides of the storage box are welded and fixedly connected with downward pressing buckles for fixing the top sealing cover.

[0020] Through the above technical solution, when the top sealing cover is fixed by pressing the buckle, the spring presses down the pressing plate, so that the stacked metal strips are pressed downward, allowing the metal strips to pass through the backflow preventer.

[0021] Furthermore, the backflow preventer includes a fixed mounting bracket fixedly connected to the side wall of the storage box, two symmetrically arranged limiting guide pillars are fixedly connected to the inner side of the fixed mounting bracket, extrusion slots are opened on both sides of the storage box at the position of the fixed mounting bracket, an extrusion slider is slidably connected to the extrusion slot position, the limiting guide pillar is slidably connected to the side wall of the extrusion slider, and a reset compression spring is fixedly connected between the extrusion slider and the inner wall of the fixed mounting bracket.

[0022] Through the above technical solution, the fixed mounting frame supports the entire structure of the backflow preventer, and the limiting guide column can support and limit the extrusion slider so that the extrusion slider can slide in the horizontal direction. The upper surface of the extrusion slider is arranged in an arc shape away from the fixed mounting frame. After the metal bar under the backflow preventer is transmitted out, the lowermost metal bar is pressed to the position below the backflow preventer under the action of downward pressure, and there is no arc-shaped slope under the extrusion slider, so the metal bar will not be squeezed above the backflow preventer, and the reset compression spring allows the extrusion slider to be quickly reset.

[0023] Furthermore, the punching structure includes an assembly bracket fixedly connected to the side wall of the storage box, the assembly bracket is fixedly connected to a punching hydraulic press, an induction feeding mechanism is fixedly connected to a position below the outer wall of the punching hydraulic press, the telescopic end of the punching hydraulic press faces downward and is fixedly connected to a mounting plate, and the lower surface of the mounting plate is fixedly connected to a punching mold.

[0024] Through the above technical solution, the punching hydraulic press can be fixedly installed by assembling the bracket. The induction feeding mechanism can energize the power motor when the punching hydraulic press is reset to transport the metal strip. The induction feeding mechanism is disconnected when the punching hydraulic press is pressed down, so that the metal strip to be punched is located directly below the punching die. The metal strip is punched through the punching die. The mounting plate can threadably fix the punching die, making it convenient to replace punching dies of different models.

[0025] Furthermore, the inductive feeding mechanism includes a fixed mounting ring fixedly connected to the outer wall of the punching hydraulic press, the outer wall of the fixed mounting ring is fixedly connected to a conductive separation frame, the conductive separation frame is made of insulating material, and two symmetrically arranged conductive pole blocks are provided on both sides of the inner side of the conductive separation frame, and a number of evenly distributed compression springs are fixedly connected between the conductive pole blocks and the inner wall of the conductive separation frame.

[0026] Through the above technical solution, the fixed mounting ring can fix the induction feeding mechanism on the outer wall of the punching hydraulic press. The conductive separation frame is made of insulating material to avoid leakage. The conductive pole blocks can turn on or off the circuit when they contact each other.

[0027] Furthermore, the lower surfaces of the two conductive pole blocks that are close to each other are inclined, and an insulating separation plate with a "convex" shape for separating the two conductive pole blocks is provided below the conductive separation frame. The upper surfaces of the conductive pole blocks are fixedly connected with internal terminals, and the upper surface of the conductive separation frame is fixedly connected with two symmetrically arranged external terminals. The insulating separation plate is fixedly connected to the upper surface of the mounting plate, the bottom of the insulating separation plate is insulated, and two conductive conductive parts are provided above the insulating separation plate.

[0028] Through the above technical solution, the compression spring makes the conductive pole block fully contact with the conductive part above the insulating separation plate, so that the conductive pole blocks can be in contact with each other and conduction can be achieved. The bottom of the insulating separation plate is made of insulating material, which will not short-circuit when connected to the conductive pole block when moving upward, and the two external terminals are respectively connected to the positive and negative poles of the power supply through wires, and the external terminals are then connected to the two internal terminals on the same side through wires, and the two internal terminals on the other side are connected to the power motor through wires.

[0029] The beneficial effects of the present invention are as follows: (1) The present invention can realize that the metal strip is uniformly and stably conveyed on the surface of the punching processing platform by setting an anti-backflow device and a metal strip conveying structure, and the upper and lower surfaces are tightly clamped, and no deviation occurs during conveyance, so that the punching quality is high, and the waste chips and finished products generated by punching are collected in a centralized manner, so that the equipment has a high degree of mechanization, does not require excessive human resources, and effectively reduces labor costs; (2) The present invention sets an induction feeding mechanism, when the punching hydraulic press is pressed down, the insulating separation plate moves down, and the conductive pole blocks on the side away from each other are disconnected, so that the power motor is powered off, and the metal sheet remains stationary, and can be punched by the punching die. When the punching hydraulic press moves up and resets, the two conductive parts above the insulating separation plate connect the conductive pole blocks on the side away from each other, so that the power motor is started, and the metal sheet moves normally, realizing conveyance, and avoiding the metal sheet moving all the time to affect normal punching.

[0052] At this time, the punching hydraulic press 60 is in a retracted state, and the conductive part above the insulating separation plate 623 connects the two conductive pole blocks 622 that are far away from each other, so that the power motor 10 is energized, and the conveying teeth 52 rotate, and under the action of the anti-backflow device 73 and the pressure guide wheel 12, the metal strip is conveyed normally, so that the metal strip to be punched moves to the bottom of the punching die 64, and the telescopic end of the mounting plate 63 moves down, so that the insulating separation plate 623 moves down and separates from the conductive pole blocks 622 that are far away from each other, so that the power motor 10 is powered off, and the metal strip will not be conveyed. The punching die 64 accurately punches the metal strip to form a bus, and the waste generated by punching falls to the lower position of the punching processing platform 1 through the punching discharge hole 8 for centralized collection. When the punching hydraulic press 60 is reset, the induction feeding mechanism 62 is reset, so that the power motor 10 is energized, and the metal strip and the punched bus continue to be conveyed. When the bus is pushed to the position of the discharge hole 3, the bus falls into the punching processing platform 1 through the discharge hole 3 for centralized collection.
