Description

Technical Field

[0001] This utility model relates to the field of punching die technology, and in particular to a quick-change device for multi-angle punching dies for square and rectangular tubes. Background Technology

[0002] Square and rectangular tubes are a general term for square and rectangular tubes, which are steel pipes with equal or unequal side lengths. They are made from strip steel through a process of rolling. Square and rectangular tubes have a hollow structure, which makes them lighter in weight while maintaining the same bending and torsional strength. Compared with solid steel, they can save a lot of material and effectively reduce the weight of the structure. Square and rectangular tubes need to be punched during production. By punching holes of specific shapes and sizes into the square and rectangular tubes, they can be connected to other components.

[0003] However, square and rectangular tubes serve different purposes, and their punching dies have different specifications and are applicable to different scenarios. To produce square and rectangular tubes for different purposes, the punches need to be replaced. Replacing punches with traditional dies requires cumbersome steps such as screw disassembly and positioning adjustment, which may take tens of minutes or even longer, resulting in low replacement efficiency. The long replacement time affects the production progress of square and rectangular tubes. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-4 This utility model provides a quick-change device for a multi-angle punching die for rectangular tubes, comprising: a base 1; two first supports 2 fixedly connected to the upper surface of the base 1, arranged left and right; a sleeve 3 rotatably connected inside the first support 2; a placement rack 4 fixedly connected inside the sleeve 3; a through groove 5 provided inside the placement rack 4; two gear rings 6 fixedly connected to the outer surface of the sleeve 3, arranged left and right; the first support 2 is slidably connected to the gear rings 6; a second support 7 fixedly connected to the upper surface of the base 1; a dual-axis motor 8 fixedly connected inside the second support 7; a rotating shaft 9 fixedly connected to the output end of the dual-axis motor 8; a gear 10 fixedly connected to the end of the rotating shaft 9 away from the dual-axis motor 8; the gear 10 meshes with the gear rings 6; the first support 2 is slidably connected to the gear 10; and the first support 2 is slidably connected to the gear 10, arranged left and right.

[0019] A hydraulic cylinder 11 is fixedly connected to the upper surface of the base 1. A connecting plate 12 is fixedly connected to the upper end of the hydraulic cylinder 11. A connecting block 13 is fixedly connected to the lower surface of the connecting plate 12. A T-shaped groove 14 is provided inside the connecting block 13. A T-shaped block 15 is movably connected inside the T-shaped groove 14. A punch 16 is fixedly connected to the lower surface of the T-shaped block 15. Two sliding grooves 17 are provided inside the connecting block 13 and are distributed left and right. A locking block 18 is slidably connected to the inner surface of the sliding groove 17. The rear surface of the locking block 18 contacts the T-shaped block 15. A sliding rod 19 is fixedly connected to the left end of the locking block 18. The interior of the connecting block 13 is slidably connected to the sliding rod 19. A spring 20 is provided on the outer surface of the sliding rod 19. The left end of the spring 20 is fixedly connected to the bottom of the groove 17. The right end of the spring 20 is fixedly connected to the locking block 18. A lever 21 is fixedly connected to the left end of the sliding rod 19. The right surface of the lever 21 contacts the connecting block 13. The lower surface of the connecting plate 12 is slidably connected to the lever 21.

[0020] Working principle: By passing the rectangular tube through the interior of the placement rack 4, the hydraulic rod drives the connecting plate 12 to press down, which in turn drives the connecting block 13 to press down. The pressing down of the connecting block 13 drives the punch 16 to press down and punch the rectangular tube. After one side of the rectangular tube is punched, the dual-axis motor 8 is started. The dual-axis motor 8 drives the rotating shaft 9 to rotate, which in turn drives the gear 10 to rotate. The rotating gear 10 drives the gear ring 6 to rotate, which in turn drives the sleeve 3 to rotate. The sleeve 3 drives the placement rack 4 to rotate, which in turn drives the rectangular tube inside the placement rack 4 to rotate, thus punching holes in different positions of the rectangular tube. When performing a punching operation and needing to replace the punch 16, pull the two levers 21. Lever 21 causes the sliding rod 19 to slide, which in turn causes the locking block 18 to slide, thus freeing the T-block 15 from its restraint. At this point, the punch 16 can be removed along with the T-block 15. To replace the punch 16 with the T-block 15, pull the lever 21 to retract the locking block 18 into the slide groove 17. When the T-block 15 slides to the bottom of the T-groove 14, release the lever 21. Under the force of the spring 20, the spring rebounds, causing the locking block 18 to adhere to the front surface of the T-block 15, thereby replacing the punch 16.

[0021] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
