[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] like Figure 1-5 As shown, a cutting device for processing fire doors includes a worktable 1, a cutting mechanism located on the worktable 1, a first motor 2 located on the worktable 1, a threaded rod 3 connected to the output end of the first motor 2, a movable table 5 connected to the threaded rod 3, a guide rod 4 passing through the movable table 5 and arranged parallel to the threaded rod 3, and a clamping mechanism for pressing the door frame against the worktable 1. The two ends of the threaded rod 3 are respectively connected to the output end of the first motor 1 and the worktable. The clamping mechanism includes a U-shaped push plate 21 located above the worktable 1 and a sliding assembly connected to the U-shaped push plate 21. The components include a T-shaped rod 16, an L-shaped rod 15 that is sleeved on the T-shaped rod 16 and slides along the T-shaped rod 16, a sliding plate 13 that is fixedly connected to the bottom of the L-shaped rod 15, a first spring 14 whose two ends are respectively connected to the sliding plate 13 and the inner surface of the worktable 1, a moving plate 12 located on the moving table 5 and cooperating with the bottom of the L-shaped rod 15 to allow the L-shaped rod 15 to move in the vertical direction, a second spring 17 that is sleeved on the T-shaped rod 16, and the two ends of the second spring 17 that are fixedly connected to the top of the L-shaped rod 15 and the bottom of the T-shaped rod 16, respectively. The T-shaped rod 16 is an inverted T-shape.

[0017] The workbench 1 is equipped with rollers 22, and a U-shaped push plate 21 is located directly above the rollers 22. The door frame to be cut is placed on the rollers 22, and then the U-shaped push plate 21 presses the door frame firmly. The workbench 1 is equipped with a first mounting side and a second mounting side, with an included angle of 90° between the first mounting side and the second mounting side. Both the first mounting side and the second mounting side are equipped with U-shaped push plates 21. The cutting mechanism is located between the first mounting side and the second mounting side, which are arranged vertically.

[0018] Two movable plates 12 are provided, located on one side of the threaded rod 3 and the other on the side of the guide rod 4. The movable plate 12 located on the threaded rod 3 side has a first inclined plate at its left end, and the movable plate 12 located on the guide rod 4 side has a second inclined plate at its right end. When the movable table 5 moves away from the first motor 2 and performs cutting, the first inclined surface of the slide plate 13 located on the threaded rod 3 side passes through the first inclined plate and enters below the movable plate 12, so that the U-shaped push plate 21 presses against the frame strip and performs cutting.

[0019] The sliding assembly includes a sliding rod 18 fixedly connected to the side of the T-shaped rod 16, a strip hole located on the side of the U-shaped push plate 21 and inclined, and a fixed rod 19 whose two ends are fixedly connected to the inner surface of the strip hole. The other end of the sliding rod 18 is sleeved on the fixed rod 19 and moves along the length of the fixed rod 19. A third spring 20 is provided on the sliding rod 18. The two ends of the third spring 20 are connected to the sliding rod 18 and the fixed rod 19 respectively. The elastic force of the third spring 20 is less than that of the second spring 17. The L-shaped rod 15 drives the second spring 17 to move downward. Then the second spring 17 presses the T-shaped rod 16 and the sliding rod 18 to move downward. The sliding rod 18 moves along the fixed rod 19, that is, while pressing the door frame, it drives the door frame to move.

[0020] The cutting mechanism includes a fixed plate 10 located on the moving table 5, a cutting blade 11 connected to the fixed plate 10 via a rotating shaft 9, a second gear 8 fixedly mounted on the rotating shaft 9, and a first gear 7 meshing with the second gear 8. The center of the first gear 7 is connected to the output end of the second motor 6, and the rotating shaft 9 is rotatably mounted on the fixed plate 10 via a bearing.

[0021] A collection box 23 is provided on the workbench 1. The collection box 23 is located at the bottom of the workbench 1 and is used to collect the chips and waste generated during cutting.

[0022] The working principle is as follows: When in use, place the frame strips of the two fire door frames on the rollers 22 on both sides of the workbench 1 and make the long strips of the frame strips stick to the first and second mounting sides on the workbench 1. Then start the first motor 2 and the second motor 6. The first motor 2 drives the threaded rod 3 to rotate, causing the moving table 5 to move towards the rollers 22. At the same time, the moving table 5 slides on the guide rod 4, and the moving table 5 drives the cutting blade 11 to move. The second motor 6 drives the first gear 7 to rotate. The first gear 7 drives the rotating shaft 9 to rotate through meshing with the second gear 8, that is, drives the cutting blade 11 to rotate. The moving table 5 drives the moving plates 12 on both sides to move.

[0023] After the moving platform 5 moves a certain distance towards the first motor 2, the moving plate 12 and sliding plate 13 on one side of the threaded rod 3 come into contact, causing the sliding plate 13 to move downward and stretch the first spring 14. The sliding plate 13 drives the L-shaped rod 15 to move downward. The L-shaped rod 15 pushes the T-shaped rod 16 and U-shaped push plate 21 downward through the second spring 17. Since the elastic force of the second spring 17 is greater than that of the third spring 20, when the U-shaped push plate 21 contacts the frame strip, it continues to move with the moving plate 12. The sliding rod 18 moves downward and slides on the fixed rod 19. The third spring 20 is compressed, causing the U-shaped push plate 21 to push the frame strip to move, so that the top surface of the frame strip contacts the second mounting side of the worktable 1. After both sides of the frame strip contact the worktable 1, the second spring 17 is compressed as the L-shaped rod 15 continues to move, causing the U-shaped push plate 21 to press the door frame tightly. As the moving table 5 continues to move, the sliding plate 13 slides at the bottom of the moving plate 12, and the U-shaped push plate 21 maintains the pressure on the frame strip. The movement of the cutting blade 11 cuts one end of the frame strip at a 45-degree angle, and the cut material falls into the collection box 23. At the same time, the second inclined plate of the moving plate 12 on one side of the guide rod 4 is located at the bottom of the L-shaped rod on the side of the guide rod 4. That is, the second inclined plate pushes the L-shaped rod 15 upward, thereby pushing the sliding plate 13 on one side of the guide rod 4 to move upward.

[0024] After the cutting blade 11 moves to the side away from the first motor and cuts the frame strip, the moving plate 12 on the threaded rod 3 side will disengage from the sliding plate 13. At this time, the first spring 14 will reset, which will drive the sliding plate 13 and the L-shaped rod 15 to reset. The second spring 17 and the third spring 20 will reset, causing the T-shaped rod 16 to reset. That is, the U-shaped push plate 21 first moves to the side away from the first motor 2, driving the frame strip to move to the side away from the first motor 2, and then moves upward to reset. Subsequently, the first motor 2 reverses, causing the moving table 5 to move to the side of the first motor 2. At this time, the sliding plate 13 on the guide rod 4 side will press the frame strip in the same way, and the cutting blade 11 will cut the door frame on the other side at a 45-degree angle.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
