Description

Technical Field

[0001] This utility model belongs to the technical field of punching and corner cutting devices, and particularly relates to a punching and corner cutting device for processing ultra-high voltage transmission towers. Background Technology

[0002] Ultra-high voltage (UHV) AC transmission refers to AC transmission projects and related technologies with voltage levels of 1000kV and above. UHV transmission technology is characterized by long distance, large capacity, low loss, and economy. UHV AC transmission requires the use of UHV transmission towers for power transmission.

[0003] For example, patent CN215614186U discloses a punching and corner-cutting device for sheet metal shell processing, including a corner-cutting support and a corner-cutting top plate. The corner-cutting top plate is fixedly connected to the corner-cutting support through four sets of support columns. A corner-cutting bottom plate is fixedly installed on the upper end of the corner-cutting support. A vertically downward corner-cutting cylinder is fixedly installed on the corner-cutting top plate. A corner-cutting upper seat is fixedly installed at the output end of the corner-cutting cylinder. A corner-cutting upper plate is fixedly installed at the lower end of the corner-cutting upper seat. The corner-cutting upper plate and the corner-cutting bottom plate cooperate to drill and cut corners on the shell sheet. A feeding component for feeding and conveying the shell sheet is installed on the corner-cutting support. This utility model facilitates the subsequent forming processing of the shell sheet by drilling and corner-cutting. The automated feeding and drilling and corner-cutting processes effectively reduce manual steps in the processing, reduce processing costs, and effectively improve processing efficiency.

[0004] Existing punching and corner-cutting devices for UHV transmission tower processing suffer from strip displacement after punching, leading to changes in the subsequent punching position of the strip. Therefore, we propose a new punching and corner-cutting device for UHV transmission tower processing. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a punching and corner-cutting device for processing ultra-high voltage transmission towers, thereby preventing the strips from shifting after punching.

[0006] In view of this, the present invention provides a punching and corner-cutting device for processing ultra-high voltage transmission towers, including a punching base, a punching frame fixedly connected to the top edge of the punching base, a pneumatic push rod fixedly connected to the top of the punching frame, a lifting frame fixedly connected to the output end of the pneumatic push rod, a punching mold fixedly connected to the bottom end of the lifting frame, a corner-cutting mold provided on one side of the punching mold, a punching pad fixedly connected to the top of the punching base, a positioning screw provided on the inner wall of the punching base, a sliding plate threadedly connected to the outer wall of the positioning screw, positioning guide grooves provided at both ends of the sliding plate, a connecting column slidably connected in the groove of the positioning guide groove, a telescopic base plate installed on the outer wall of the connecting column, a limit rod penetrating through the inner wall of the telescopic base plate, a telescopic frame fixedly connected to both ends of the telescopic base plate, and a guide roller screwed to one end of the telescopic frame.

[0007] Based on the above structure, the positioning screw drives the two sets of positioning guide grooves to slide synchronously through the sliding plate. The sliding of the positioning guide grooves drives the telescopic base plate to slide along the outer wall of the limiting rod through the connecting column. The sliding of the telescopic base plate causes the guide roller at one end of the telescopic frame to fit against both sides of the strip, thereby limiting the strip and preventing the strip from shifting after stamping, which would cause the subsequent stamping position of the strip to change.

[0008] Preferably, the punching die is strip-shaped and the corner-cutting die is rhomboid. In this embodiment, the strip-shaped punching die and the rhomboid corner-cutting die facilitate the control of the punching and corner-cutting shapes of the strip.

[0009] Preferably, the outer wall of the stamping pad has punching slots that correspond one-to-one with the punching die and the corner cutting die. In this embodiment, it is beneficial for the punching die and the corner cutting die to slide through the stamping pad to perform punching and corner cutting operations on the strip.

[0010] Preferably, the positioning guide groove is inclined, and the telescopic base plate forms a telescopic structure with the positioning guide groove, the connecting column, and the limiting rod. In this embodiment, the positioning guide groove slides through the connecting column to drive the telescopic base plate to slide along the outer wall of the limiting rod, thereby realizing the stable sliding operation of the telescopic base plate.

[0011] Preferably, the guide rollers are provided in two sets, and the two sets of guide rollers are symmetrical about the central axis of the stamping pad. In this embodiment, the sliding of the telescopic base plate drives the guide roller at one end of the telescopic frame to fit against both sides of the strip, thereby limiting the position of the strip.

[0012] Preferably, an adjusting frame is fixedly connected to one end of the stamping base. An adjusting screw is provided on the inner wall of the adjusting frame. An adjusting base is threadedly connected to the outer wall of the adjusting screw. A connecting frame is fixedly connected to both ends of the adjusting base. A limit baffle is fixedly connected to one end of the connecting frame. In this embodiment, the adjusting screw drives the adjusting base to slide, and the sliding of the adjusting base drives the limit baffle at one end of the connecting frame to slide synchronously. Then, the strip is placed on the stamping pad, so that one end of the strip fits against the outer wall of the limit baffle, thereby realizing the adjustment operation of the cutting length of the strip.

[0013] Preferably, the connecting frame is L-shaped, and the limiting baffle and the stamping pad are located on the same horizontal line. In this embodiment, by setting the connecting frame in an L-shape, it is beneficial to improve the stability of the limiting baffle sliding, so that one end of the strip is in contact with the outer wall of the limiting baffle, thereby realizing the adjustment operation of the cutting length of the strip.

[0014] The beneficial effects of this utility model are:

[0015] 1. The punching and corner cutting device for processing ultra-high voltage transmission towers, by setting a limit baffle, adjusting the screw to drive the adjusting base to slide, the adjusting base to drive the limit baffle at one end of the connecting frame to slide synchronously, and then placing the strip on the punching pad, so that one end of the strip fits against the outer wall of the limit baffle, thereby realizing the adjustment operation of the cutting length of the strip corner.

[0016] 2. The punching and corner cutting device for processing ultra-high voltage transmission towers uses guide rollers and positioning screws to drive two sets of positioning guide grooves to slide synchronously through a sliding plate. The sliding of the positioning guide grooves drives the telescopic base plate to slide along the outer wall of the limiting rod through the connecting column. The sliding of the telescopic base plate causes the guide roller at one end of the telescopic frame to fit against both sides of the strip, thereby limiting the strip and preventing the strip from shifting after punching, which would cause the subsequent punching position of the strip to change.

[0025] This application discloses a punching and corner-cutting device for processing ultra-high voltage transmission towers, including a punching base 1, a punching frame 2 fixedly connected to the top edge of the punching base 1, a pneumatic push rod 3 fixedly connected to the top of the punching frame 2, a lifting frame 4 fixedly connected to the output end of the pneumatic push rod 3, a punching mold 5 fixedly connected to the bottom end of the lifting frame 4, a corner-cutting mold 6 provided on one side of the punching mold 5, a punching pad 7 fixedly connected to the top of the punching base 1, a positioning screw 8 provided on the inner wall of the punching base 1, a sliding plate 9 threadedly connected to the outer wall of the positioning screw 8, positioning guide grooves 10 opened at both ends of the sliding plate 9, a connecting column 11 slidably connected in the groove of the positioning guide groove 10, a telescopic base plate 12 installed on the outer wall of the connecting column 11, a limit rod 13 penetrating through the inner wall of the telescopic base plate 12, a telescopic frame 14 fixedly connected to both ends of the telescopic base plate 12, and a guide roller 15 screwed to one end of the telescopic frame 14.

[0026] Based on the above structure, the positioning screw 8 drives the two sets of positioning guide grooves 10 to slide synchronously through the sliding plate 9. The sliding of the positioning guide grooves 10 drives the telescopic base plate 12 to slide along the outer wall of the limiting rod 13 through the connecting column 11. The sliding of the telescopic base plate 12 drives the guide roller 15 at one end of the telescopic frame 14 to fit with both sides of the strip, thereby limiting the strip and preventing the strip from shifting after stamping, which would cause the subsequent stamping position of the strip to change.

[0027] In one embodiment, the punching die 5 is strip-shaped, and the chamfering die 6 is rhomboid in shape.

[0028] In this embodiment, the strip-shaped punching die 5 and the rhomboid-shaped chamfering die 6 facilitate the control of the punching and chamfering shapes of the strip.

[0029] In one embodiment, the outer wall of the stamping pad 7 is provided with punching grooves that correspond one-to-one with the punching die 5 and the chamfering die 6.

[0030] In this embodiment, it is advantageous for the punching die 5 and the corner cutting die 6 to slide through the stamping pad 7 to perform punching and corner cutting operations on the strip.

[0031] In one embodiment, the positioning guide groove 10 is inclined, and the telescopic base plate 12 forms a telescopic structure with the positioning guide groove 10, the connecting column 11, and the limiting rod 13.

[0032] In this embodiment, the positioning guide groove 10 slides through the connecting column 11 to drive the telescopic base plate 12 to slide along the outer wall of the limiting rod 13, thereby realizing the stable sliding operation of the telescopic base plate 12.

[0033] In one embodiment, two sets of guide rollers 15 are provided, and the two sets of guide rollers 15 are symmetrical about the central axis of the stamping pad 7.

[0034] In this embodiment, the sliding base plate 12 drives the guide roller 15 at one end of the telescopic frame 14 to fit against both sides of the strip, thereby limiting the position of the strip.

[0035] In one embodiment, an adjusting frame 16 is fixedly connected to one end of the stamping base 1. An adjusting screw 17 is provided on the inner wall of the adjusting frame 16. An adjusting base 18 is threadedly connected to the outer wall of the adjusting screw 17. A connecting frame 19 is fixedly connected to both ends of the adjusting base 18. A limit baffle 20 is fixedly connected to one end of the connecting frame 19.

[0036] In this embodiment, the adjusting screw 17 drives the adjusting base 18 to slide, and the sliding of the adjusting base 18 drives the limiting baffle 20 at one end of the connecting frame 19 to slide synchronously. Then, the strip is placed on the stamping pad 7 so that one end of the strip is in contact with the outer wall of the limiting baffle 20, thereby realizing the adjustment operation of the cutting length of the strip.

[0037] In one embodiment, the connecting frame 19 is L-shaped, and the limiting baffle 20 and the stamping pad 7 are located on the same horizontal line.

[0038] In this embodiment, by setting an "L"-shaped connecting frame 19, it is beneficial to improve the stability of the sliding of the limiting baffle 20, so that one end of the strip fits against the outer wall of the limiting baffle 20, thereby realizing the adjustment operation of the cutting length of the strip.

[0039] In this embodiment, the punching and corner-cutting device for processing ultra-high voltage transmission towers is used to first adjust the cutting length of the strip corner. The operator rotates the adjusting screw 17, which drives the adjusting base 18 to slide. The sliding of the adjusting base 18 drives the limiting baffle 20 at one end of the connecting frame 19 to slide synchronously. Then, the strip is placed on the punching pad 7 so that one end of the strip is in contact with the outer wall of the limiting baffle 20, thereby realizing the adjustment operation of the cutting length of the strip corner.

[0040] Then, the operator rotates the positioning screw 8, which drives the two sets of positioning guide grooves 10 to slide synchronously through the sliding plate 9. The sliding of the positioning guide grooves 10 drives the telescopic base plate 12 to slide along the outer wall of the limiting rod 13 through the connecting column 11. The sliding of the telescopic base plate 12 drives the guide roller 15 at one end of the telescopic frame 14 to fit against both sides of the strip, thereby limiting the strip and preventing the strip from shifting after stamping, which would cause the subsequent stamping position of the strip to change.

[0041] Finally, the pneumatic push rod 3 drives the punching mold 5 and the corner cutting mold 6 at the bottom of the lifting frame 4 to slide vertically. The punching mold 5 and the corner cutting mold 6 slide through the stamping pad 7 to perform punching and corner cutting operations on the strip.
