[0002] In the production process of distribution boxes, as a core component for power transmission, copper bars need to be processed through multiple processes such as cutting, punching, and bending to meet installation requirements. Traditional processing methods usually use split equipment or independent workstations to complete each process: first, the copper bar is cut to a preset length by a cutting device, then manually transferred to a punching device for surface hole processing, and finally transported to a bending station to complete angle forming.

[0003] Chinese Patent Application for Invention CN117359317A discloses an integrated copper bar cutting, punching and bending machine, which includes a working platform, a cutting mechanism and a punching mechanism respectively arranged at both ends of the short side of the working platform.

[0027] Figures 1-9 This is the best embodiment of the present utility model. The following will further describe the present utility model in conjunction with the attached Figures 1-9 drawings.

[0028] Referring to the attached Figures 1-9 drawings, a copper bar cutting and punching integrated device for a distribution box includes a body 1. A shearing mechanism 2 is fixedly installed on the front side of the body 1. The shearing mechanism 2 includes a first fixed seat, a first lifting frame and a cutting tool.

The cutting tool is fixedly installed at the top of the first lifting frame. A punching mechanism 3 is fixedly installed on the front side of the body 1. The punching mechanism 3 includes a second fixed seat, a second lifting frame and a punching die. The second fixed seat is fixedly installed on the front side of the body 1. The second lifting frame is arranged on the surface of the second fixed seat. The punching die is rotatably installed at the top of the second lifting frame. The top of the first lifting frame is higher than the punching die, and the discharge end of the shearing mechanism 2 corresponds to the feeding end of the punching mechanism 3. A feeding channel 4 is fixedly installed on one side of the body 1, and the discharge end of the punching mechanism 3 corresponds to the feeding end of the feeding channel 4. A storage box is fixedly installed at the discharge end of the feeding channel 4. A bending mechanism 5 is fixedly installed on the top of the body 1. The bending mechanism 5 includes a third fixed seat, a hydraulic cylinder, an outer die and an inner die. The third fixed seat is fixedly installed on the top of the body 1. The hydraulic cylinder is fixedly installed on the top of the third fixed seat. The movable end of the hydraulic cylinder is fixedly installed with the outer die. The inner die is fixedly installed on the top of the third fixed seat. An auxiliary feeding fixture 6 is fixedly installed on the top of the body 1, and the auxiliary feeding fixture 6 is located behind the feeding end of the body 1.

[0029] The shearing mechanism 2, the punching mechanism 3, and the bending mechanism 5 can all adopt existing technologies. For example, the relevant structures disclosed in the Chinese utility model patent with the publication number CN117359317A can be used. The specific structures of the shearing mechanism 2, the punching mechanism 3, and the bending mechanism 5 will not be elaborated here.

[0030] The auxiliary feeding fixture 6 includes a support plate 603, a lateral moving member, a clamping moving member, and a rotating moving member. One end of the lateral moving member is fixedly installed on the other side of the machine body 1, and the other end thereof is fixedly connected to the support plate 603. A clamping moving member is arranged on the top of the support plate 603, and a rotating moving member is arranged inside the support plate 603. The moving end of the rotating moving member is slidably connected to the moving end of the clamping moving member.

[0031] Specifically, the first lifting frame drives the cutter to move up and down, so as to segmentally shear the plate passing through the shearing mechanism 2 to obtain a copper row of the required size. The second lifting frame pushes the punching die downward, so as to punch the plate passing through the punching mechanism 3. The sheared and punched plate is conveyed to the storage box through the feeding channel 4. The hydraulic cylinder pushes the outer die close to the inner die, so as to bend the plate placed at the bending mechanism 5 to obtain a copper row of the required shape. The lateral moving member drives the support plate 603 to move laterally, so as to control the lateral position of the plate punching. The moving end of the clamping moving member pushes the moving end of the rotating moving member to slide, so as to control the clamping and fixing of the plate. The moving end of the rotating moving member rotates, so as to push the plate to move longitudinally and control the longitudinal position of the plate punching.

[0032] A control panel is provided at the rear side of the machine body 1, and a feeding channel is opened at the top of the machine body 1. The feeding channel is located behind the shearing mechanism 2.

[0033] Specifically, the operation of each mechanism of the device is regulated and set through the control panel, and the plate is conveyed to the auxiliary feeding fixture 6 through the feeding channel.

[0034] The lateral moving member of the auxiliary feeding fixture 6 includes a fixing plate 601 and an electric push rod 602. The fixing plate 601 is fixedly installed on one side of the machine body 1, and the electric push rod 602 is fixedly installed on the fixing plate 601. The free end of the electric push rod 602 is fixedly connected to the support plate 603.

[0035] Specifically, the electric push rod 602 pushes the support plate 603 to move laterally to adjust the lateral position of the plate.

[0036] The rotating and moving part of the auxiliary feeding fixture 6 includes a servo motor 604, a rotating shaft 605, transmission wheels 606 and clamping parts 607. The servo motor 604 is fixedly installed at the rear side of the support plate 603. The output end of the servo motor 604 penetrates through the support plate 603 and is fixedly connected to the rotating shaft 605. The transmission wheels 606 are rotatably installed on the rotating shaft 605. The number of the transmission wheels 606 is two groups, and the two groups of transmission wheels 606 are respectively located on the upper and lower sides of the support plate 603. The clamping parts 607 are slidably installed inside the sliding grooves of the support plate 603. The number of the clamping parts 607 is four groups, and the four groups of clamping parts 607 are arranged in a circular array with respect to the transmission wheels 606. Conductive gear sets are provided on the surfaces of the rotating shaft 605 and the clamping parts 607, and are meshed with the transmission wheels 606.

[0037] Specifically, the servo motor 604 drives the rotating shaft 605 to rotate. Through the meshing connection of the conductive gear sets and the transmission wheels 606, the clamping parts 607 are driven to rotate, so that the clamping parts 607 push the plate in contact with their bottoms to move longitudinally, and the longitudinal position of the plate is adjusted.

[0038] The rotating shaft 605 is composed of a horizontal shaft and a vertical shaft. The horizontal shaft is fixedly connected to the output end of the servo motor 604, and the vertical shaft is fixedly connected to the inside of the support plate 603, and the horizontal shaft is perpendicular to the vertical shaft. The conductive gear sets include bevel gears and spur gears. Bevel gears are coaxially fixed on one side of the two groups of transmission wheels 606 close to the horizontal shaft and on the horizontal shaft, and the bevel gear on the horizontal shaft is located between the bevel gears on the two groups of transmission wheels 606 and is meshed with them. The number of spur gears is four groups, which are respectively fixedly installed on the four groups of clamping parts 607. Two groups of spur gears are respectively arranged on both sides of the plate to be conveyed, and there is a height difference between the spur gears on both sides of the plate to be conveyed, and they are respectively meshed with the upper and lower two groups of transmission wheels 606.

[0039] Specifically, the servo motor 604 drives the horizontal shaft to rotate. Through the transmission of the bevel gears, the transmission wheels 606 are driven to rotate on the surface of the vertical shaft. Then through the conduction of the spur gears, the clamping parts 607 are driven to rotate, so that the clamping parts 607 push the plate to move. By meshing the two groups of transmission wheels 606 with the spur gears on the surfaces of the clamping parts 607 on both sides respectively, since the rotation directions of the two groups of transmission wheels 606 are opposite, the clamping parts 607 on both sides of the plate can convey the plate and push the plate to move stably.

[0040] The clamping and moving member of the auxiliary feeding fixture 6 includes a bidirectional screw 608, a pressing plate 609, a worm gear 6010, a worm 6011 and a dial 6012. A connecting plate is fixedly installed on the surface of the support plate 603. The bidirectional screw 608 is rotatably installed on one side of the connecting plate. The pressing plate 609 is threadedly installed on the surface of the bidirectional screw 608. The number of pressing plates 609 is two groups. The two groups of pressing plates 609 are symmetrically arranged with respect to the bidirectional screw 608. A through groove is formed on the surface of the pressing plate 609, and the top end of the clamping member 607 is attached to the inner wall of the through groove of the pressing plate 609. The threads at both ends of the bidirectional screw 608 have opposite helix directions.

[0041] Specifically, the rotation of the bidirectional screw 608 drives the two groups of pressing plates 609 to slide on the surface of the support plate 603, so that the pressing plates 609 push the clamping members 607 on both sides of the transmission wheel 606 to move towards or away from each other, thereby clamping and fixing or releasing the plate between the two clamping members 607.

[0042] The worm gear 6010 is rotatably installed on the other side of the connecting plate, and the worm gear 6010 is fixedly connected to one end of the bidirectional screw 608. The worm 6011 is rotatably installed on the other side of the connecting plate, and the worm gear 6010 is meshed with the worm 6011. The dial 6012 is fixedly installed on one end of the worm 6011.

[0043] Specifically, by turning the dial 6012 to drive the worm 6011 to rotate, the worm 6011 drives the worm gear 6010 to rotate, and the worm gear 6010 controls the bidirectional screw 608 to rotate, thereby preventing the bidirectional screw 608 from rotating by itself or being pushed and rotated by the outside world.

[0044] In summary, when the utility model is in use, the staff feeds the plate to be processed into the feeding channel of the machine body 1, so that the plate is located between the bottom ends of the clamping members 607 on both sides of the driving wheel 606, and the dial 6012 is pushed to rotate. Through the conduction of the dial 6012 and the worm 6011, the bidirectional screw 608 is driven to rotate on the surface of the connecting plate, thereby driving the two pressing plates 609 to move towards each other along the surface of the bidirectional screw 608, so that the clamping members 607 with the top ends located in the through grooves of the pressing plates 609 are pushed. The clamping members 607 slide inside the sliding grooves of the support plates 603. At the same time, the spur gears on the surfaces of the clamping members 607 rotate along the surface of the driving wheel 606, and the clamping members 607 on both sides of the driving wheel 606 approach each other until their bottom ends fit against both sides of the plate to clamp and fix it. The staff waits at the bending mechanism 5 and drives the servo motor 604 to drive the horizontal axis of the rotating shaft 605 to rotate. The bevel gear on its surface meshes with the bevel gear on the surface of the driving wheel 606, thereby driving the two driving wheels 606 to rotate on the surface of the vertical shaft. The two driving wheels 606 respectively mesh with the spur gears on the surfaces of the clamping members 607 on both sides, thereby driving the clamping members 607 on both sides to rotate. The clamping members 607 push the plate in contact with their bottom ends to move back and forth, passing the plate through the shearing mechanism 2 to the punching die at the punching mechanism 3 for punching. The longitudinal position of the plate is adjusted by the rotation of the clamping members 607, and the transverse position of the plate is adjusted by the electric push rod 602 driving the support plate 603 to move, so that the position to be punched corresponds to the punching die. After punching, the plate is pulled longitudinally, so that the part of the plate to be sheared moves to the cutter of the punching mechanism 3 for shearing, obtaining a copper bar product that has been sheared and punched. The plate is longitudinally moved again to push the product forward and fall into the feeding channel 4, and it slides and is stored in the storage box in the feeding channel 4. The staff takes it out and puts it into the bending mechanism 5 for bending. By repeating the operation, copper bar products that have been sheared and punched are continuously fed into the storage box, and the staff only needs to repeat the bending work at the bending mechanism 5, reducing the inconvenience and tediousness of the staff transporting the copper bars between various processes and switching between various processes.

[0045] The above is only a preferred embodiment of the present utility model, and it does not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution content of the present utility model still belong to the protection scope of the technical solution of the present utility model.
