Description

Technical Field

[0001] The utility model relates to the technical field of blanking machines, in particular to a blanking machine for cutting doors and windows. Background Technique

[0002] More and more people choose plastic-steel doors and windows. When making doors and windows, the plastic-steel needs to be processed into a style that can be assembled with each other. Generally, the plastic-steel is cut at an angle and then assembled into a complete plastic-steel door and window. When cutting the door and window profiles, a blanking machine for cutting doors and windows is required.

[0003] In the patent application with the authorization announcement number CN212331181U, the authorization announcement date of January 12, 2021, and the name of "A Blanking Machine for Cutting Doors and Windows", it includes a support plate. A first cutting device is fixedly connected to the upper surface of the support plate. A feeding device is arranged at one end of the upper surface of the support plate away from the first cutting device. The first cutting device includes a first housing, a first cutting motor and a first hydraulic cylinder. The first hydraulic cylinder fixedly connects the first cutting motor and the first housing. The output shaft of the first cutting motor is fixedly connected with a first cutting blade. A first bearing plate is fixedly connected to the side wall of the first housing. A first cutting groove is opened on the side wall of the first housing. One end of the first cutting groove away from the first bearing plate is inclined towards the end away from the feeding device. A second cutting groove is opened on the upper surface of the first bearing plate. The second cutting groove communicates with the bottom end of the first cutting groove. The utility model has the effects of ensuring the cutting accuracy, improving the working efficiency, reducing the production cost and reducing the workload of the staff at the same time.

[0004] When the existing blanking machine for cutting doors and windows is in use, although two sets of cutting structures arranged symmetrically can cut both ends of the profile at the same time, making the cut angles at both ends of the profile have opposite inclination directions, which is convenient for splicing the profiles to form a rectangular door and window frame later. However, this cutting method not only requires two sets of cutting structures to be set, but also needs to cut off the waste at the ends of the profiles to cut out the profiles with cut angles having opposite inclination directions at both ends. This not only makes the production cost of the equipment relatively high, but also generates a large amount of waste, making the production cost of the door and window frame relatively high and inconvenient to use. Therefore, we propose a blanking machine for cutting doors and windows to solve the problems raised above. Content of the Utility Model

[0018] (1) The feeding mechanism drives the workpiece to move towards the box body. After the workpiece moves to the cutting position, the second hydraulic rod clamps and fixes the left and right sides of the workpiece through the first clamping plate, and the third hydraulic rod clamps and fixes the upper and lower sides of the workpiece through the second clamping plate. Then, the cutting mechanism cuts a 45° chamfer at the end of the workpiece. Then, the first clamping plate releases the workpiece, and the second motor drives the rotating frame to rotate 180° through the gear and the transmission gear, so that the rotating frame drives the workpiece to swap positions up and down through the second clamping plate. Then, the feeding mechanism drives the workpiece to continue moving, and then continues to cut the workpiece. Then, the workpiece is flipped again to make the workpiece continue to move, and then the workpiece is cut, so that a workpiece with chamfers with opposite inclination directions at both ends can be directly cut by a single cutting mechanism, and no waste will be generated, effectively saving the production cost of the door and window frame.

[0019] (2) When the second motor works, it can drive the gear to rotate. The gear can drive the rotating frame to rotate through the meshing with the transmission gear, and then can drive the workpiece to swap positions up and down. When controlling the rotation of the rotating frame, the rotating frame rotates reciprocally within a range of 180°, thereby avoiding the torsion of the pipeline of the third hydraulic rod and enabling the third hydraulic rod to work normally.

[0028] Please refer to Figures 1 to 3 , a blanking machine for cutting doors and windows, including a base 1. A box body 2 is fixedly connected to the top of the base 1. A knife groove 3 is opened above the middle of the box body 2. Among them,

[0029] A cutting mechanism is arranged inside the box body 2 corresponding to the knife groove 3. Support plates 11 are symmetrically and fixedly connected to the tops of both sides of the shorter side of the base 1. Second hydraulic rods 12 are symmetrically installed on one side of the support plates 11 close to the middle of the box body 2. A first clamping plate 13 is installed at the telescopic end of the second hydraulic rod 12. Rotating brackets 14 are symmetrically installed on the tops of both sides of the base 1 close to the longer side of the box body 2. A rotating frame 15 is rotatably connected to the inner side of the rotating brackets 14;

[0030] On the inner side of the rotating frame 15, the third hydraulic rods 16 are symmetrically installed up and down. The telescopic ends of the third hydraulic rods 16 are installed with the second clamping plates 17. On the ring side of the rotating frame 15 near the end, the transmission gears 18 are fixedly connected at equal intervals. On the top of the base 1 corresponding to the rotating frame 15, a second motor 19 is installed. On the shaft end of the second motor 19 corresponding to the transmission gear 18, a gear 20 is installed. On the top of the base 1 far from the box body 2, a feeding mechanism is provided;

[0031] The feeding mechanism drives the workpiece to move towards the box body 2. After the workpiece moves to the cutting position, the second hydraulic rod 12 clamps and fixes the left and right sides of the workpiece through the first clamping plate 13. The third hydraulic rod 16 clamps and fixes the upper and lower sides of the workpiece through the second clamping plate 17. Then, the cutting mechanism cuts a 45° cut angle at the end of the workpiece. Then, the first clamping plate 13 releases the workpiece, so that the second motor 19 drives the rotating frame 15 to rotate 180° through the gear 20 and the transmission gear 18, so that the rotating frame 15 drives the workpiece to exchange positions up and down through the second clamping plate 17. Then, the feeding mechanism drives the workpiece to continue to move. After that, the workpiece is continuously cut. Then, the workpiece is continuously flipped and the workpiece continues to move, and then the workpiece is cut, so that a workpiece with cut angles with opposite inclination directions at both ends can be directly cut by a single cutting mechanism, and at the same time, no waste is generated, effectively saving the production cost of the door and window frame.

[0032] Please refer to Figures 1 to 3 As shown in the figure, the cutting mechanism includes a support 4. On the top of the base 1 corresponding to the inner side of the box body 2, the support 4 is fixedly connected. Above the support 4, a sliding frame 5 is slidably arranged. On the inner wall of the box body 2 corresponding to the sliding frame 5, a first hydraulic rod 8 is installed. The telescopic end of the first hydraulic rod 8 is fixedly connected to the sliding frame 5. Inside the sliding frame 5, a first motor 9 is installed. On the shaft end of the first motor 9 corresponding to the tool groove 3, a cutting blade 10 is installed. On one side of the support 4 corresponding to the sliding frame 5, chutes 6 are symmetrically opened. At the bottom of the sliding frame 5 corresponding to the chutes 6, sliders 7 are fixedly connected. The cutting blade 10 is inclined, and the inclination angle of the cutting blade 10 is 45°. When the workpiece moves, the first hydraulic rod 8 is in a shortened state, so that the cutting blade 10 is located on one side of the workpiece. After the workpiece moves to the designated position, the workpiece is limited. The first motor 9 drives the cutting blade 10 to rotate. At the same time, the first hydraulic rod 8 pushes the sliding frame 5 to slide towards the workpiece, thereby driving the cutting blade 10 to move towards the workpiece, and through the inclined cutting blade 10, it is convenient to cut a 45° cut angle at the end of the workpiece.

[0033] Please refer to Figures 1 to 3The pitch of the transmission teeth 18 is equal to the pitch of the gear 20, and the transmission teeth 18 mesh with the gear 20. When the second motor 19 is working, it can drive the gear 20 to rotate. The gear 20 can drive the rotating frame 15 to rotate by meshing with the transmission teeth 18, and then drive the workpiece to switch the upper and lower positions. When the rotating frame 15 is controlled to rotate, the rotating frame 15 is reciprocated within a range of 180°, thereby avoiding the pipeline of the third hydraulic rod 16 from twisting, so that the third hydraulic rod 16 can work normally. The feeding mechanism includes a support The support frame 21 is symmetrically installed on the top of the base 1 away from the box body 2, and the inner side of the support frame 21 near the top is rotatably connected with a conveying roller 22. A third motor 23 is installed on the outer side of the support frame 21. The shaft end of the third motor 23 is fixedly connected to the conveying roller 22. When the third motor 23 is working, it drives the conveying roller 22 to rotate. The conveying roller 22 can drive the workpiece to be loaded through friction. When the workpiece is loaded, the first clamping plate 13 and the second clamping plate 17 both release the workpiece, which is convenient for the conveying roller 22 to drive the workpiece to be loaded.

[0034] Working principle: When using this door and window cutting machine, Figures 1 to 3 As shown, first, the workpiece is driven to move toward the box body 2 by the feeding mechanism. After the workpiece moves to the cutting position, the second hydraulic rod 12 clamps and fixes the left and right sides of the workpiece through the first clamping plate 13, and the third hydraulic rod 16 clamps and fixes the upper and lower sides of the workpiece through the second clamping plate 17. Then, the end of the workpiece is cut with a 45° cutting angle by the cutting mechanism. Then, the first clamping plate 13 releases the workpiece, and the second motor 19 drives the rotating frame 15 to rotate 180° through the gear 20 and the transmission tooth 18, so that the rotating frame 15 drives the workpiece to change its position up and down through the second clamping plate 17. Then, the feeding mechanism drives the workpiece to continue to move, and then the workpiece continues to be cut. Then, the workpiece is turned over, and the workpiece continues to move, and then the workpiece is cut. A single cutting mechanism can directly cut a workpiece with opposite cutting angles at both ends without generating waste. , effectively saving the production cost of door and window frames. When the workpiece moves, the first hydraulic rod 8 is in a shortened state, so that the cutting blade 10 is located on one side of the workpiece. After the workpiece moves to the specified position, the workpiece is limited, and the first motor 9 drives the cutting blade 10 to rotate. At the same time, the first hydraulic rod 8 pushes the sliding frame 5 to slide toward the workpiece, thereby driving the cutting blade 10 to move toward the workpiece, and through the inclined cutting blade 10, it is convenient to cut a 45° cutting angle on the end of the workpiece, and when the second motor 19 is working, it can drive the gear 20 to rotate, and the gear 20 can drive the rotating frame 15 to rotate by meshing with the transmission tooth 18, thereby driving the workpiece to switch the upper and lower positions. When controlling the rotation of the rotating frame 15, the rotating frame 15 is rotated back and forth within a range of 180°, thereby avoiding the twisting of the pipeline of the third hydraulic rod 16, so that the third hydraulic rod 16 can work normally.

[0035] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0036] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
