[0016] 3. Beneficial effects:

[0017] Adopting the technical solution provided by the present utility model, compared with the prior art, the door and window drain hole punching machine of the present utility model has the following specific contents:

[0018] (1)When punching the door and window profiles is required, the door and window profiles are loaded through the loading device. When the position where the door and window profiles need to be punched moves below the punching rod, the second hydraulic rod drives the first clamping plate and the second clamping plate to move towards the door and window profiles, so that the first clamping plate directly abuts against the surface of the door and window profiles, while the second clamping plate abuts against the door and window profiles through the support frame, fixing the door and window profiles. Then the first hydraulic rod drives the punching rod to move downward to punch the door and window profiles. At the same time, the second clamping plate supports the bottom of the punched hole of the door and window profiles through the support frame, which can effectively prevent the punched hole of the door and window profiles from deforming during punching, avoid subsequent correction of the door and window profiles, and thus improve the punching efficiency of the door and window profiles.

[0019] (2)When the support frame needs to be replaced according to the shape of the door and window profiles, the pull rod drives the block to move out of the inside of the clamping groove against the spring force, so that the support frame can drive the guide rod out of the guide groove, and at the same time can drive the T-shaped block out of the T-shaped groove, completing the disassembly of the support frame. Then take out the support frame to be installed, so that the support frame drives the guide rod to insert into the guide groove, and at the same time the support frame drives the T-shaped block to insert into the T-shaped groove. When the T-shaped block abuts against the curved surface of the block, the block is pushed against the spring force and retracts into the inside of the block groove. When the block groove is aligned with the clamping groove, the spring pushes the block into the clamping groove, fixing the T-shaped block in the T-shaped groove and at the same time fixing the guide rod in the guide groove, and thus the installation of the support frame can be completed. Through this quick disassembly and assembly mechanism, the support frame can be quickly replaced, and thus it is convenient to quickly replace the support frame according to the shape of the door and window profiles.

[0029] Please refer to Figures 1 to 4 , a punching machine for drainage holes of doors and windows, comprising a base 1, a top frame 2 is arranged on the top of the base 1, and the four corners of the bottom of the top frame 2 are fixedly connected to the base 1 through columns 3. Among them,

[0030] At the middle of the top end of the top frame 2, a first hydraulic rod 4 is installed. At the telescopic end of the first hydraulic rod 4, a lifting frame 5 is installed. At the bottom of the lifting frame 5, a punching seat 6 is installed. At the bottom of the punching seat 6, a punching rod 7 is fixedly connected. At the middle of the top end of the base 1, a door and window profile 8 is provided. At the top of both sides of the base 1, fixing frames 9 are symmetrically and fixedly connected. On one side of the fixing frame 9 close to the door and window profile 8, a second hydraulic rod 10 is installed;

[0031] At the telescopic ends of the second hydraulic rods 10 on both sides of the base 1, a first clamping plate 11 and a second clamping plate 12 are respectively installed. On one side of the second clamping plate 12 close to the door and window profile 8, a support frame 13 is installed. At the position corresponding to the punching rod 7 on the support frame 13, a punching slot 14 is penetrated. The support frame 13 and the second clamping plate 12 are detachably connected through a quick disassembly and assembly mechanism;

[0032] When it is necessary to punch the door and window profile 8, the door and window profile 8 is loaded through a loading device (the loading device is a prior art and has nothing to do with the problems to be solved by this solution, so it is directly cited). When the position where the door and window profile 8 needs to be punched moves below the punching rod 7, the second hydraulic rod 10 drives the first clamping plate 11 and the second clamping plate 12 to move towards the door and window profile 8, so that the first clamping plate 11 directly abuts against the surface of the door and window profile 8, while the second clamping plate 12 abuts against the door and window profile 8 through the support frame 13 to fix the door and window profile 8. Then the first hydraulic rod 4 drives the punching rod 7 to move downward to punch the door and window profile 8. At the same time, the second clamping plate 12 supports the bottom of the punching position of the door and window profile 8 through the support frame 13, which can effectively prevent the punching position of the door and window profile 8 from deforming during punching, avoid subsequent correction of the door and window profile 8, and thus improve the punching efficiency of the door and window profile 8.

[0033] Please refer to Figures 1 to 4 , the positions of the punching rod 7 and the punching slot 14 correspond to each other, and the external dimension of the punching rod 7 matches the internal dimension of the punching slot 14. The top of the support frame 13 at the punching slot 14 fits against the bottom of the punching position of the door and window profile 8.

[0034] Please refer to Figures 1 to 4, the quick disassembly and assembly mechanism includes a bracket 15. The second clamping plate 12 is fixedly connected to one side of the bottom end of the support frame 13 with a bracket 15. The bracket 15 is symmetrically penetrated by a guide groove 16. The support frame 13 is fixedly connected with a guide rod 17 at the bottom corresponding to the guide groove 16. A T-shaped groove 18 is opened at the top of the second clamping plate 12 close to the support frame 13. A T-shaped block 19 is fixedly connected to one side of the support frame 13 corresponding to the T-shaped groove 18. A clamping groove 20 is opened on the side of the T-shaped block 19 away from the support frame 13. A clamping block groove 21 is opened on the inner wall of the T-shaped groove 18 corresponding to the clamping groove 20. A pull rod groove 22 is opened on the outside of the second clamping plate 12 corresponding to the clamping block groove 21. A spring 23 is installed inside the clamping block groove 21. A clamping block 24 is installed on the opening side of the spring 23 close to the clamping block groove 21. A pull rod 25 is fixedly connected to one end of the clamping block 24 corresponding to the pull rod groove 22. The guide rod 17 is a cylinder, and the outer diameter of the guide rod 17 is matched with the inner diameter of the guide groove 16. The clamping block 24 is a rectangular column, and the upper part of the clamping block 24 away from the spring 23 is a curved surface. When it is necessary to replace the support frame 13 according to the shape of the door and window profile 8, the clamping block 24 is driven by the pull rod 25 to move out of the inside of the clamping groove 20 against the elastic force of the spring 23, so that the support frame 13 can drive the guide rod 17 to move out of the guide groove 16, and at the same time can drive the T-shaped block 19 to move out of the T-shaped groove 18, and the support frame 13 is disassembled. Then, the support frame 13 to be installed is taken out, and the support frame 13 drives the guide rod 17 to insert into the guide groove 16. At the same time, the support frame 13 drives the T-shaped block 19 to insert into the T-shaped groove 18. When the T-shaped block 19 abuts against the curved surface of the clamping block 24, the clamping block 24 is driven to shrink into the inside of the clamping block groove 21 against the elastic force of the spring 23. When the clamping block groove 21 is aligned with the clamping groove 20, the spring 23 pushes the clamping block 24 to insert into the clamping groove 20, fixes the T-shaped block 19 in the T-shaped groove 18, and at the same time fixes the guide rod 17 in the guide groove 16, so as to complete the installation of the support frame 13. Through this quick disassembly and assembly mechanism, the support frame 13 can be quickly replaced, and thus it is convenient to quickly replace the support frame 13 according to the shape of the door and window profile 8.

[0035] Working principle: When using this punching machine for the drainage holes of doors and windows, as Figures 1 to 4As shown, first, when punching the door and window profile 8 is required, the door and window profile 8 is loaded by a loading device (the loading device is an existing technology and has nothing to do with the problems to be solved by this solution, so it is directly cited). When the position where the door and window profile 8 needs to be drilled moves below the punching rod 7, the second hydraulic rod 10 drives the first clamping plate 11 and the second clamping plate 12 to move towards the door and window profile 8, so that the first clamping plate 11 directly abuts against the surface of the door and window profile 8, while the second clamping plate 12 abuts against the door and window profile 8 through the support frame 13 to fix the door and window profile 8. Then the first hydraulic rod 4 drives the punching rod 7 to move downward to punch the door and window profile 8. At the same time, the second clamping plate 12 supports the bottom of the drilled hole of the door and window profile 8 through the support frame 13, which can effectively prevent the drilled hole of the door and window profile 8 from deforming during drilling, avoid subsequent correction of the door and window profile 8, and thus improve the punching efficiency of the door and window profile 8. When the support frame 13 needs to be replaced according to the shape of the door and window profile 8, the pull rod 25 drives the block 24 to move out of the inside of the card slot 20 against the elastic force of the spring 23, so that the support frame 13 can drive the guide rod 17 out of the guide groove 16, and at the same time can drive the T-shaped block 19 out of the T-shaped groove 18 to complete the disassembly of the support frame 13. Then take out the support frame 13 to be installed, so that the support frame 13 drives the guide rod 17 to insert into the guide groove 16, and at the same time the support frame 13 drives the T-shaped block 19 to insert into the T-shaped groove 18. When the T-shaped block 19 abuts against the curved surface of the block 24, the block 24 is pushed to shrink into the inside of the block slot 21 against the elastic force of the spring 23. When the block slot 21 is aligned with the card slot 20, the spring 23 pushes the block 24 to insert into the card slot 20 to fix the T-shaped block 19 in the T-shaped groove 18 and at the same time fix the guide rod 17 in the guide groove 16, and thus the installation of the support frame 13 can be completed. Through this quick disassembly and assembly mechanism, the support frame 13 can be quickly replaced, and thus it is convenient to quickly replace the support frame 13 according to the shape of the door and window profile 8.

[0036] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
