Technical Field

[0001] The utility model relates to the technical field of busbar trough contact processing, in particular to tongue-pressing type busbar trough contact processing equipment. Background Art

[0002] Busbar ducts, enclosed metal structures composed of copper and aluminum busbar posts, are used to distribute high power to various components in distributed systems. They are increasingly replacing wires and cables in indoor low-voltage power transmission trunk projects. When connecting busbar ducts in certain locations, the contacts must be machined to ensure stability after connection.

[0003] Related technology (publication number: CN108889841B) discloses a tongue-pressed busbar duct contact and its processing equipment. The disclosed technical solution: The contact and busbar body are integrally formed, eliminating the traditional method of press-riveting the contact to the busbar body. This eliminates the problem of poor clamping force between the contact and the busbar body, and ensures good contact between the contact and the busbar body, enhancing safety. Furthermore, the process is convenient, time-saving, and labor-saving, reducing worker labor intensity and improving work efficiency.

[0004] In the above-mentioned disclosed technical solution, the following problems were found in the related technology: since the bus duct generally has four contacts, and the four contacts are located in a vertical row, when the contacts are processed into tongue shapes, they need to be processed one by one, and the position of the bus duct needs to be continuously changed during the processing. In this regard, we have proposed a new type of tongue-pressing bus duct contact processing equipment.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background technology section of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The following is a combination of specific implementation cases and attached Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0030] A device for processing a tongue-pressing busbar duct contact comprises a processing table 1, a punch 2 being provided on the top of the processing table 1, a die 3 being provided above the punch 2, and a stamping drive component for driving the die 3 to press the punch 2. The punch 2 is fixed to the surface of the processing table 1 in a close-fitting manner, and the die 3 is driven to move above the punch 2 by the movable end of the stamping drive component, so that the die 3 moves toward the punch 2, thereby processing the busbar duct contact into a tongue-pressing shape. A feed frame 4 is slidably provided at the bottom of the processing table 1, and a propulsion assembly for adjusting the position of the feed frame 4 is provided at the bottom of the processing table 1.

[0031] The feed rack 4 slides in contact with the bottom of the processing table 1. The position of the feed rack 4 is adjusted by the propulsion assembly so that the busbar duct drives the contacts to move onto the processing table 1. By adjusting the position of the feed rack 4, each contact is moved forward and backward so that the contacts of the busbar duct can be processed one by one in a tongue-pressing manner, thereby ensuring the efficiency of the busbar duct contact processing. The inner cavity of the feed rack 4 is provided with a loading rack 5 for longitudinal sliding, and the bottom of the feed rack 4 is provided with a lifting drive component for adjusting the height of the loading rack 5. A through groove is provided on the surface of the feed rack 4 from the center to the outside, and the outer walls on both sides of the loading rack 5 slide in contact with the inner walls of the through groove. The busbar duct is fixed on the loading rack 5, and the longitudinal position of the loading rack 5 on the feed rack 4 is adjusted by the lifting drive component.

[0032] The bus duct contacts are sequentially adjusted to positions corresponding to the processing table 1 based on their positions. The feed frame 4 is then driven laterally by the push assembly, driving the bus duct contacts toward the punch 2 on the processing table 1. The punch drive assembly then moves the die 3 toward the punch 2, thereby forming a tongue-shaped portion of the bus duct contact. The push assembly and lift drive assembly then adjust the positions of the bus duct contacts one by one. Through these gradual position changes, each bus duct contact is processed individually, thereby improving the efficiency of the bus duct contact processing process.

[0033] A guide frame 19 is symmetrically fixedly mounted below the processing table 1, affixed to the bottom of the feed frame 4. The guide frames 19 are fixedly mounted on the inner walls of the processing table 1's four legs, so that two parallel guide frames 19 are respectively affixed to the two legs on either side. The two guide frames 19 are spaced a certain distance from the bottom of the processing table 1, allowing the feed frame 4 to slide between the guide frames 19 and the processing table 1. A dovetail guide groove 25 is defined at the top of the guide frame 19, and a dovetail slider 27 is symmetrically fixedly mounted on the bottom of the feed frame 4, slidingly disposed within the inner cavity of the dovetail guide groove 25.

[0034] Through the sliding cooperation between the T-shaped dovetail slider 27 and the T-shaped dovetail guide groove 25, the stability of the feed frame 4 during movement is improved, and position deviation is avoided, thereby ensuring the stability of the feed frame 4 during the lateral position movement process, and further ensuring the quality of the busbar trough contact processing.

[0035] Among them, the propulsion assembly includes a screw 14 that is rotatably arranged below the guide frame 19. The external thread of the screw 14 is connected to the drive seat 16, and the drive seat 16 is fixedly installed at the bottom of the feed frame 4. The fixed seats 28 are fixedly installed on both side surfaces of the two guide frames 19, and bearings are embedded in the opposite surfaces of the two fixed seats 28. The two ends of the screw 14 are respectively embedded in the inside of the two bearings. The motor 17 is fixed on the surface of one fixed seat 28 through the machine cover 18. The output shaft of the motor 17 passes through the inner cavity of the corresponding fixed seat 28 and is fixedly connected to the corresponding end of the screw 14. The motor 17 is electrically connected to the external power supply through a wire. The drive seat 16 is located between the two guide frames 19 and is fixed at the right bottom edge of the feed frame 4. The motor 17 is a drive motor with forward and reverse adjustment.

[0036] When adjusting the horizontal position of the bus duct contact, the motor 17 is connected to the power supply so that the output shaft of the motor 17 drives the screw 14 to rotate, and the drive seat 16 threadedly connected to the screw 14 drives the feed rack 4 to move, so that the feed rack 4 drives the bus duct contact to move toward the processing table 1, making the operation of the bus duct position adjustment process more convenient.

[0037] It is worth noting that an orientation column 15 is provided below the guide frame 19 and is parallel to the lead screw 14. The drive seat 16 is sleeved on the outside of the orientation column 15. The two ends of the orientation column 15 are respectively fixedly mounted vertically on the opposite surfaces of the two fixing seats 28, and the drive seat 16 slides against the outer wall of the orientation column 15.

[0038] In the process of rotating the screw 14 to make the drive seat 16 adjust the position of the feed rack 4, the drive seat 16 slides against the outer wall of the directional column 15 at the same time. The directional column 15 parallel to the screw 14 ensures the stability of the moving direction of the drive seat 16, avoids position deviation, and thus ensures the accuracy of the busbar trough contact processing position.

[0039] In addition, the stamping drive component includes a top frame 8 fixedly mounted on the top of the processing table 1. The top frame 8 is fixedly mounted on the top of the processing table 1 through support columns 24 at the four edges, and the top frame 8 is located above the punch 2. A hydraulic cylinder 9 is provided through the inner cavity of the top frame 8, and a through hole is longitudinally opened in the middle of the top frame 8. The aperture of the through hole corresponds to the cylinder end of the hydraulic cylinder 9, so that the cylinder end of the hydraulic cylinder 9 is fixedly embedded in the inside of the through hole, and the hydraulic cylinder 9 is in a position perpendicular to the top frame 8.

[0040] The die 3 is fixedly mounted on the movable end of the hydraulic cylinder 9 , and the movable end of the hydraulic cylinder 9 is vertically fixedly mounted on the top of the die 3 .

[0041] When the busbar duct contact is subjected to tongue-pressing processing, the movable end of the hydraulic cylinder 9 drives the die 3 to move, so that the die 3 moves toward the busbar duct contact on the punch 2, thereby punching the busbar duct contact into a tongue-pressing shape.

[0042] Anti-deflection guide rods 10 are installed on the outer wall of the die 3, parallel to the hydraulic cylinder 9. These rods extend through the inner cavity of the top frame 8 and outward. Connecting seats 22 are fixedly mounted on the outer walls of both sides of the die 3. The lower ends of the anti-deflection guide rods 10 are vertically fixed to the tops of the connecting seats 22. The upper ends of the anti-deflection guide rods 10 pass through the top frame 8 and are vertically fixed to the bottom of the movable frame. The anti-deflection guide rods 10, parallel to the movable end of the hydraulic cylinder 9, ensure the stability of the die 3's movement direction, thereby guaranteeing the quality of the busbar duct contact processing.

[0043] The lifting drive assembly includes an electric push rod 7 fixedly mounted below the feed frame 4. The movable end of the push rod 7 is fixedly mounted to the bottom of the loading frame 5. The push rod 7 is vertically fixed to the top center of a bracket 29, which is fixedly mounted to the bottom of the feed frame 4. The movable end of the push rod 7 is vertically fixed to the bottom of the loading frame 5. The push rod 7 is electrically connected to an external power source via a wire. Adjusting the height of the loading frame 5 by the push rod 7 sequentially shifts the busbar contacts, allowing them to be processed sequentially.

[0044] The top of the feed frame 4 is provided with a guide rod 11. Four guide rods 11 are respectively fixed vertically on both sides of the top of the feed frame 4. The loading frame 5 is connected to the outside of the guide rod 11 through the connecting ears on both sides. The loading frame 5 drives the connecting ears to slide against the outer wall of the guide rod 11.

[0045] When switching the bus duct contact to be processed, the loading frame 5 drives the bus duct to move up and down, and at the same time drives the connecting ear to slide against the outer wall of the guide rod 11, thereby ensuring the stability of the bus duct contact position adjustment process.

[0046] Furthermore, a guide post 6 is fixedly mounted on the bottom of the processing table 1, and a stabilizing seat 21 is fixedly mounted on the top of the feed frame 4 on the side away from the guide frame 19. The stabilizing seat 21 is sleeved on the outside of the guide post 6. The sliding fit between the stabilizing seat 21 and the guide post 6 prevents the left end of the feed frame 4 from shifting, and the right end of the feed frame 4 is limited by the guide frame 19, thereby ensuring the overall stability of the feed frame 4.

[0047] The top of the punch 2 is provided with a pressing groove 13 opposite to the die 3. After the groove 3 enters the pressing groove 13, the quality of the busbar duct contact stamping is guaranteed.

[0048] This embodiment is a tongue-pressing busbar duct contact processing device, and its working principle is: first, the busbar duct is fixed on the loading frame 5, and the height position of the loading frame 5 is adjusted by the electric push rod 7, and the busbar duct contact is adjusted to the position corresponding to the processing table 1.

[0049] Then connect the motor 17 to the power supply so that the output shaft of the motor 17 drives the screw 14 to rotate, so that the drive seat 16 threadedly connected to the screw 14 drives the feed frame 4 to move, so that the feed frame 4 drives the contacts of the bus duct to move toward the processing table 1.

[0050] Then, the movable end of the hydraulic cylinder 9 drives the die 3 to move, so that the die 3 moves toward the busbar duct contact on the punch 2. After the die 3 enters the pressing groove 13, the busbar duct contact is processed.
