Description

Technical Field

[0001] This utility model relates to the field of hole punching pliers, and in particular to a manual hole punching pliers for aluminum alloy doors and windows. Background Technology

[0002] Currently, door and window opening and drainage are completed using door and window punching machines. These machines are 1.2 meters long, 1.2 meters wide, and 1.2 meters high, making them inconvenient to move. Furthermore, they are mostly made of steel and weigh over 500 kg. Drainage holes need to be pre-punched during door and window production. If this step is forgotten before assembling the finished product, the only solution is to disassemble the finished door and window, punch the drainage holes, and then reassemble it. This causes significant inconvenience to production, and repeated disassembly and reassembly also affects the lifespan of the doors and windows.

[0003] An existing manual hydraulic pliers for opening drain holes (publication number: CN211679546U) has at least the following drawbacks:

[0004] In the aforementioned patent, holes are made using both a concave die and a drain hole punch. However, the size of the pliers head is fixed, which limits the maximum distance between the concave die and the drain hole punch. When drilling holes in some larger profiles, it becomes impossible to fit the pliers head over the profile. Furthermore, when it is necessary to replace the concave die and the drain hole punch and to remove the bolts, the operating space between the concave die and the drain hole punch is relatively narrow, making it inconvenient to use and presenting certain limitations. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a manual drilling pliers for aluminum alloy doors and windows.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0025] Reference Figures 1-5 A manual drilling pliers for aluminum alloy doors and windows includes a plier head 1, with a drilling head 2 disposed inside the plier head 1. It also includes an adjustment assembly for adjusting the drilling head 2. The adjustment assembly includes a movable frame 3, which is movably sleeved on the outside of the plier head 1. A first limiting hole 5 is provided on one side of the plier head 1. A fixing plate 6 is movably sleeved inside the first limiting hole 5 and fixedly sleeved with the movable frame 3. A threaded hole 7 is provided on the top surface of the fixing plate 6, and a first threaded post 8 is threadedly connected to the inner circular wall of the threaded hole 7. The top and bottom surfaces of the first limiting hole 5 are respectively provided with… The device includes a limiting groove 9, which is threadedly connected to the first threaded post 8. A circular groove is provided on the bottom surface of the limiting groove 9. A worm gear 10 is movably sleeved on the inner circular wall of the circular groove. The worm gear 10 is fixedly sleeved with the first threaded post 8. A fixing hole 11 is provided on one side of the pliers head 1. A worm 12 is movably sleeved on the inner circular wall of the fixing hole 11. Two limiting rings 13 are movably sleeved on the outer circular wall of the worm 12. The limiting rings 13 are fixedly sleeved with the fixing hole 11. A drilling assembly is provided for drilling holes in aluminum alloy door and window profiles. A replacement assembly is provided for replacing the drilling head 2.

[0026] In use, when the user needs to drill holes in the profile and adjust the distance between the drilling head 2 and the upper mold 20, the crank 14 is manually turned to drive the worm gear 12 to rotate. The rotating worm gear 12 drives the worm wheel 10 to rotate, and the rotating worm wheel 10 drives the first threaded post 8 to rotate. Thus, the first threaded post 8 and the threaded hole 7 convert the rotational motion into linear motion. Therefore, the fixed plate 6 and the moving frame 3 are limited by the first limiting hole 5, so that the fixed plate 6 moves up and down inside the first limiting hole 5, and the moving frame 3 moves to increase the distance between the drilling head 2 and the upper mold 20. Thus, the drilling head 2 and the upper mold 20 are suitable for some profiles with thicker cross sections.

[0027] In this embodiment, the drilling assembly includes: a fixed frame 15, which is movably sleeved on the outside of the movable frame 3. Second circular through holes are respectively opened on both sides of the fixed frame 15. A fixed post 17 is movably sleeved on the inner wall of the second circular through hole. The fixed post 17 is fixedly installed with the movable frame 3. A support hole 21 is opened on the top surface of the movable frame 3. A movable plate 4 is movably sleeved inside the support hole 21. A second limiting hole 16 is opened on one side of the movable plate 4. The second limiting hole 16 is movably sleeved with the fixed frame 15. The replacement assembly includes: two second threaded posts. 18. Two second threaded posts 18 are fixedly installed on the top surface of the movable plate 4 and the inner top surface of the pliers head 1, respectively. An upper mold 20 is provided on the inner top surface of the pliers head 1. Two third circular through holes are respectively opened on the top surface of the punching head 2 and the bottom surface of the upper mold 20. The third circular through holes are movably connected to the second threaded posts 18. Nuts 19 are threadedly connected to the outer circular wall surface of the second threaded posts 18. A crank 14 is fixedly installed at one end of the worm gear 12. Handles 22 are fixedly installed on the bottom surface of the pliers head 1 and the bottom surface of the fixed frame 15, respectively. The movable frame 3 is made of steel.

[0028] In use, after adjustment, hold the two handles 22 to rotate the fixing frame 15 and pull the moving plate 4 to move the punch head 2 to the bottom, so that the punch head 2 and the upper mold 20 are fitted into the outside of the profile. Manually turn the two handles 22 to rotate the fixing frame 15 and the clamp head 1, so that the fixing frame 15 pushes the moving plate 4 upward, so that the punch head 2 and the upper mold 20 cooperate to perform the punching operation. When it is necessary to replace the punch head 2 and the upper mold 20, adjust the moving frame 3 to move to the bottom, so that the punch head 2 and the upper mold 20 are separated to leave operating space, and then turn the two nuts 19 to remove them from the outside of the second threaded post 18. The punch head 2 can be removed from the outside of the second threaded post 18. The operating space is large, which is convenient for use.

[0029] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0030] When the user needs to drill holes in the profile using the provided clamp head 1, and needs to adjust the distance between the drilling head 2 and the upper mold 20, the crank handle 14 is manually turned to rotate the worm gear 12. The rotating worm gear 12 drives the worm wheel 10 to rotate, which in turn drives the first threaded post 8 to rotate. This converts the rotational motion of the first threaded post 8 and the threaded hole 7 into linear motion. The first limiting hole 5 then limits the movement of the fixed plate 6 and the moving frame 3, causing the fixed plate 6 to move up and down within the first limiting hole 5. This movement of the moving frame 3 increases the distance between the drilling head 2 and the upper mold 20, making the drilling head 2 and upper mold 20 suitable for profiles with thicker cross-sections. After adjustment, the user holds the two handles 22 to rotate the fixed frame 15, pulling the moving plate 4 to move the drilling head 2 to its lowest position, thus securing the drilling head 2 and upper mold 20 into the profile. Turning the two handles 22 rotates the fixing frame 15 and the pliers head 1, which in turn pushes the moving plate 4 upward so that the punch head 2 and the upper mold 20 can work together to perform the punching operation. When it is necessary to replace the punch head 2 and the upper mold 20, adjust the moving frame 3 to the bottom so that the punch head 2 and the upper mold 20 are separated to leave room for operation. Then, turn the two nuts 19 to remove them from the outside of the second threaded post 18, so that the punch head 2 can be removed from the outside of the second threaded post 18. The large operating space makes it convenient to use. This achieves the effect of adjusting the distance between the pliers head 1 and the punch head 2. Turning the crank handle 14 can make fine adjustments to the moving frame 3. The worm gear 12 and the worm wheel 10 have a self-locking structure, so the worm wheel 10 will not rotate on its own and the moving frame 3 will not move up and down on its own. This makes it suitable for profiles of different sizes and facilitates the replacement of the punch head 2 and the upper mold 20. It is convenient to use and quite practical.
