Description

Technical Field

[0001] The present invention relates to the technical field of door and window processing, and particularly to a trimming device for low-energy consumption door and window processing. Background Art

[0002] When doors and windows are being produced and processed, their edges need to be cut. The existing method for trimming doors and windows is usually to fix the doors and windows first, and then move the cutting machine to cut the doors and windows. When the existing trimming device is trimming, it usually only guides the cutting machine through a single-side slide rail. After long-term use, it is easy to cause the cutting machine to be unstable during movement, and the practicability is relatively low.

[0003] For this reason, the Chinese patent with the publication number "CN222588228U" discloses a "precision positioning trimming device for broken bridge door and window processing". Its main structure includes a trimming platform. Four corners of the lower surface of the trimming platform are fixedly installed with support feet. A first rectangular groove is opened on the upper surface of the trimming platform. Rectangular sliding grooves are opened on both the front and rear sides inside the first rectangular groove. A sliding plate is slidably installed inside the two rectangular sliding grooves. A clamping device is arranged on the sliding plate. Driven by a driving motor, the threaded rod rotates to drive the moving plate to move. The movement of the moving plate drives two T-shaped sliders to slide inside the corresponding T-shaped sliding grooves through the support plate and the connecting plate. By setting the T-shaped sliding groove, the T-shaped slider and the connecting plate, the movement of the support plate is limited. The double slide rail arrangement makes the cutting blade more stable during cutting.

[0004] In actual processing, the above-mentioned precision positioning trimming device for broken bridge door and window processing can only trim one side of the door and window during a single operation, resulting in relatively low work efficiency. Summary of the Invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 and Figure 2 , a trimming device for low-energy consumption window and door processing, including a trimming platform 1 with support legs 2 installed at the bottom, an extended support plate 3 arranged in the width direction of the trimming platform 1, and two cutting blades 4 capable of trimming windows and doors. First, fix the window and door to be cut on the upper surface of the trimming platform 1 according to requirements, and make the cutting area of the window and door located outside the length edge of the trimming platform 1.

[0021] In order to achieve the biaxial trimming function and thus improve the working efficiency, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, it is necessary to set up a threaded drive mechanism 5, which internally has a rotatable horizontal threaded rod 56, a moving base 58 sleeved around the outer periphery of the horizontal threaded rod 56 and capable of moving directionally when the horizontal threaded rod 56 rotates, a horizontal limiting rod 57 capable of preventing the moving base 58 from rotating, and a double-shaft motor 512 fixedly installed on the top of the moving base 58. Rotate the handwheel 55 directionally. At this time, the horizontal threaded rod 56 rotates directionally. Due to the function of the threaded structure connection, the moving base 58 will move directionally, causing the moving base 58 to move directionally to one end of the horizontal threaded rod 56. Then install the doors and windows, and start the double-shaft motor 512. At this time, the rotors of the double-shaft motor 512 will drive the two cutting blades 4 to rotate synchronously. Then reverse the handwheel 55. According to the above principle, the cutting blades 4 will perform edge cutting work from one side of the doors and windows until the cutting on this side of the doors and windows is completed, and then stop rotating the handwheel 55, thus realizing the double-shaft edge cutting function and improving the work efficiency.

[0022] For the specific structure of the threaded drive mechanism 5, please refer to Figure 3 and Figure 4 , including two symmetrical vertical support bases 51. There is a shaft installation hole 52 in the vertical support base 51. A rotatable first rotating shaft 53 is installed inside the shaft installation hole 52 of the vertical support base 51. One end of one of the first rotating shafts 53 is fixedly installed with a handwheel 55. The opposite ends of the two first rotating shafts 53 are fixedly installed with a horizontal threaded rod 56 through a first coupling 54. The two vertical support bases 51 fixedly install a horizontal limiting rod 57 directly below the horizontal threaded rod 56. The inside of the moving base 58 is provided with an internally threaded hole 59 and a limiting sliding hole 510 with both ends in an open state. The internally threaded hole 59 is installed around the outer periphery of the horizontal threaded rod 56 through a threaded structure. The limiting sliding hole 510 is sleeved around the outer periphery of the horizontal limiting rod 57. The top of the moving base 58 is fixedly installed with a motor fixing seat 511.

The threaded structure includes an internal threaded structure arranged inside the internally threaded hole 59 and an external threaded structure arranged around the outer periphery of the horizontal threaded rod 56, and the internal threaded structure matches the external threaded structure. The axis lines of the two rotors of the double-shaft motor 512 are perpendicular to the plane where the length of the edge cutting platform 1 is located.

[0023] In order to achieve edge cutting work on doors and windows at different distances, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, it is necessary to set up two hydraulic telescopic linkage mechanisms 6, which are internally provided with a hollow rotating outer shell 61 that can rotate with the rotor of the double-shaft motor 512 and is hollow inside, a piston plate 67 placed inside the hollow rotating outer shell 61 and capable of moving axially along the hollow rotating outer shell 61, and a horizontal telescopic rod 68 that can move with the piston plate 67 and drive the cutting blade 4 to rotate. It is used in cooperation with hydraulic equipment. The hydraulic equipment is used to fill the buffer liquid into the liquid flow channel 65. Under the action of the liquid pressure, the piston plate 67 will drive the horizontal telescopic rod 68 to elongate, so as to perform edge trimming work on doors and windows farther away. Due to the reaction force of the first helical spring 69, the piston plate 67 and the horizontal telescopic rod 68 will be maintained at the working length, so that the cutting blade 4 can perform edge trimming work on doors and windows at different distances.

[0024] For the specific structure of the hydraulic telescopic linkage mechanism 6, please refer to Figure 5 and Figure 6 , and it also includes a first helical spring 69. One end of the hollow rotating outer shell 61 is installed with a third coupling 62 fixedly connected to the second coupling 513. A horizontal component activity cavity 63 is arranged inside the hollow rotating outer shell 61. A liquid limiting flow cavity 64 is arranged at one end of the horizontal component activity cavity 63 close to the third coupling 62. A liquid flow channel 65 communicating with the external space and the liquid limiting flow cavity 64 and internally installed with a liquid valve is arranged on the circumferential surface of the hollow rotating outer shell 61. A piston plate 67 capable of moving axially along the horizontal component activity cavity 63 is placed inside the hollow rotating outer shell 61 at the position of the horizontal component activity cavity 63. A first rod body perforation 66 communicating with the external space is arranged at one end of the hollow rotating outer shell 61 far from the liquid limiting flow cavity 64. A horizontal telescopic rod 68 passing through the first rod body perforation 66 is fixedly installed at the end of the piston plate 67 facing the first rod body perforation 66. A first helical spring 69 in a compressed state is sleeved outside the rod body of the horizontal telescopic rod 68 inside the horizontal component activity cavity 63. One end of the horizontal telescopic rod 68 outside the hollow rotating outer shell 61 is fixedly installed at the installation end of the cutting blade 4. The structural radius of the liquid limiting flow cavity 64 is smaller than the structural radius of the horizontal component activity cavity 63. The structural shape of the cross-section of the first rod body perforation 66 is the same as that of the cross-section of the horizontal telescopic rod 68, both of which are polygonal structures, and the structural size of the cross-section of the first rod body perforation 66 matches the structural size of the cross-section of the horizontal telescopic rod 68.

[0025] In order to achieve the function of quickly fixing doors and windows, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8, it is necessary to set up an elastic pressure clamping mechanism 7, which is internally provided with a longitudinal hollow shell 71 fixedly installed on the upper surface of the extended support plate 3 and in a hollow state inside, an inner movable plate 75 placed inside the longitudinal hollow shell 71 and capable of moving along the axial direction of the longitudinal hollow shell 71, a second helical spring 77 placed inside the longitudinal hollow shell 71 and exerting a downward elastic pressure on the inner movable plate 75, and a contact plate 710 that moves with the inner movable plate 75 and can achieve a contact clamping effect on the surface of the door and window. Pull the T-shaped linkage 78 upward. When the pulling force is greater than the elastic pressure of the second helical spring 77, the second helical spring 77 will be continuously compressed, and the T-shaped linkage 78 and the contact plate 710 will move upward. Then, place the door and window on the upper surface of the trimming platform 1 according to the cutting requirements, and then release the pulling force on the T-shaped linkage 78. Under the elastic pressure of the second helical spring 77, the contact plate 710 will move downward and achieve a contact clamping effect on the door and window, thereby realizing the rapid fixing function of the door and window.

[0026] For the specific structure of the elastic pressure clamping mechanism 7, please refer to Figure 7 and Figure 8 , and it also includes a T-shaped linkage 78. The bottom of the longitudinal hollow shell 71 is provided with a bottom fixing plate 72 integrally structured with it and fixedly installed on the upper surface of the extended support plate 3. The inside of the longitudinal hollow shell 71 is provided with a longitudinal component moving cavity 73. The top of the longitudinal hollow shell 71 is provided with a second rod body perforation 74 communicating with the top of the external space and the longitudinal component moving cavity 73. Inside the longitudinal hollow shell 71 in the longitudinal component moving cavity 73, an inner movable plate 75 capable of moving along the axial direction of the longitudinal component moving cavity 73 is placed. The upper end of the inner movable plate 75 is fixedly installed with a longitudinal telescopic rod 76 passing through the second rod body perforation 74. The top of the longitudinal telescopic rod 76 outside the longitudinal hollow shell 71 is fixedly installed with a T-shaped linkage 78. A compressed second helical spring 77 is sleeved around the rod body of the longitudinal telescopic rod 76 inside the longitudinal component moving cavity 73. Two longitudinal contact rods 79 are fixedly installed at the bottom ends of the two ends of the T-shaped linkage 78. A contact plate 710 is fixedly installed at the bottom end of each longitudinal contact rod 79. The cross-sectional structure shape of the second rod body perforation 74 is the same as that of the longitudinal telescopic rod 76, both are polygonal structures, and the cross-sectional structure size of the second rod body perforation 74 matches the cross-sectional structure size of the longitudinal telescopic rod 76.

[0027] In use, it is used in conjunction with a hydraulic device. The hydraulic device is used to fill the buffer liquid into the liquid flow channel 65. Under the action of the liquid pressure, the piston plate 67 will drive the horizontal telescopic rod 68 to elongate, so as to perform the edge cutting work on the doors and windows further away. Due to the reaction force of the first helical spring 69, the piston plate 67 and the horizontal telescopic rod 68 will be maintained at the working length. Rotate the hand crank 55 directionally. At this time, the horizontal threaded rod 56 rotates directionally. Due to the function of the threaded structure connection, the moving base 58 will move directionally, so that the moving base 58 moves directionally to one end of the horizontal threaded rod 56. Pull the T-shaped linkage 78 upward. When the pulling force is greater than the elastic pressure of the second helical spring 77, the second helical spring 77 will be continuously compressed, and the T-shaped linkage 78 and the contact plate 710 will move upward. Then place the doors and windows on the upper surface of the edge cutting platform 1 according to the cutting requirements, and then release the pulling force on the T-shaped linkage 78. Under the elastic pressure of the second helical spring 77, the contact plate 710 will move downward and hold the doors and windows in a contact clamping effect. Start the double-shaft motor 512. At this time, the rotors of the double-shaft motor 512 will drive the two cutting blades 4 to rotate synchronously. Then reverse the hand crank 55. According to the above principle, the cutting blades 4 will perform the edge cutting work on one side of the doors and windows until the cutting on this side of the doors and windows is completed, and then the rotation of the hand crank 55 can be stopped.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
