Although this method is simple in structure, it has obvious drawbacks in actual use: the bolts need to be tightened or loosened one by one, the disassembly and assembly process is cumbersome and time-consuming, the blade replacement is inefficient, and the bolts are prone to loosening after long-term impact and vibration, resulting in the blade not being firmly fixed, which not only affects the consistency of the bending angle, but also poses a safety hazard of the blade falling off. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology, such as the need to tighten or loosen bolts one by one, the cumbersome and time-consuming disassembly and assembly process, the low efficiency of replacing blades, and the fact that bolts are prone to loosening after long-term impact and vibration, resulting in the blades not being securely fixed. This not only affects the consistency of bending angles but also poses a safety hazard of blades falling off. The present invention provides a blade fixing component for the cutting mechanism of a bending machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a blade fixing assembly for a bending machine cutting mechanism, comprising a bending machine body, a fixing mechanism fixedly connected to the outer surface of the bending machine body, a positioning mechanism provided on the outer surface of the fixing mechanism, the fixing mechanism including a mounting plate, the mounting plate being fixedly connected to the bending machine body, a bending blade sleeved on the inner wall of the mounting plate, a knob provided on the outer surface of the mounting plate, a bidirectional lead screw fixedly connected to the outer surface of the knob, a moving plate sleeved on the outer surface of the bidirectional lead screw, and a locking block fixedly connected to the outer surface of the moving plate.

[0006] In a preferred embodiment, the positioning mechanism includes a positioning block, a slide rod is fixedly connected to the outer surface of the positioning block, a fixing rod is sleeved on the inner wall of the slide rod, the slide rod and the fixing rod are slidably connected, and one end of the fixing rod is fixedly connected to the inner wall of the locking block.

[0007] In a preferred embodiment, a spring is sleeved on the outer surface of the fixing rod, and the two ends of the spring are respectively fixedly connected to the inner wall of the locking block and the outer surface of the sliding rod.

[0008] In a preferred embodiment, the inner wall of the mounting plate is provided with a plurality of sliding grooves, and the inner wall of the sliding grooves is slidably connected to the movable plate.

[0009] In a preferred embodiment, the inner wall of the movable plate is provided with a screw hole that matches the thread line on the outer surface of the bidirectional lead screw.

[0010] In a preferred embodiment, one end of the bidirectional lead screw is fixedly connected to a bearing, the bearing is placed inside the mounting plate, and the bearing is fixedly connected to the mounting plate.

[0011] In a preferred embodiment, one end of the bending blade is provided with a slot that matches the locking block, and the slot engages with the locking block.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention ensures the normal operation of the bending process through the main body of the bending machine. A fixing mechanism secures the bending blade, guaranteeing proper bending operation. To fix the bending blade, it is first inserted into the mounting plate. Then, by rotating a knob, a double-acting screw rotates within the bearing.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: a blade fixing assembly for a bending machine cutting mechanism, including a bending machine body 1, a fixing mechanism 2 fixedly connected to the outer surface of the bending machine body 1, a positioning mechanism 3 provided on the outer surface of the fixing mechanism 2, the fixing mechanism 2 including a mounting plate 21, the mounting plate 21 fixedly connected to the bending machine body 1, a bending blade 22 sleeved on the inner wall of the mounting plate 21, a knob 23 provided on the outer surface of the mounting plate 21, a bidirectional lead screw 24 fixedly connected to the outer surface of the knob 23, one end of the bidirectional lead screw 24 fixedly connected to... A bearing 25 is attached and placed inside the mounting plate 21. The bearing 25 is fixedly connected to the mounting plate 21. A movable plate 27 is sleeved on the outer surface of the double-acting screw 24. The inner wall of the movable plate 27 has a screw hole that matches the thread line on the outer surface of the double-acting screw 24. A locking block 28 is fixedly connected to the outer surface of the movable plate 27. One end of the bending knife 22 has a locking groove that matches the locking block 28. The locking groove and the locking block 28 are engaged and connected. The inner wall of the mounting plate 21 has multiple sliding grooves 26. The inner wall of the sliding grooves 26 is slidably connected to the movable plate 27.

[0020] In this embodiment, the bending machine body 1 ensures the normal operation of the bending work, and the bending blade 22 is fixed by the fixing mechanism 2 to ensure the normal operation of the bending work. When fixing the bending blade 22, the bending blade 22 is first inserted into the mounting plate 21. Then, the double-acting screw 24 is rotated inside the bearing 25 by rotating the knob 23. Since the double-acting screw 24 is threadedly connected to the moving plate 27, the moving plate 27 is moved in opposite directions or in the opposite direction while the double-acting screw 24 is rotating. The moving plate 27 moves inside the slide groove 26, which drives the locking block 28 to move, so that the locking block 28 engages with the slot opened in the bending blade 22, thus completing the fixing of the bending blade 22.

[0021] Example 2 like Figures 1-4As shown, the positioning mechanism 3 includes a positioning block 31, a slide rod 32 is fixedly connected to the outer surface of the positioning block 31, a fixing rod 33 is sleeved on the inner wall of the slide rod 32, the slide rod 32 and the fixing rod 33 are slidably connected, one end of the fixing rod 33 is fixedly connected to the inner wall of the locking block 28, and a spring 34 is sleeved on the outer surface of the fixing rod 33, the two ends of the spring 34 are respectively fixedly connected to the inner wall of the locking block 28 and the outer surface of the slide rod 32.

[0022] In this embodiment, when the bending blade 22 is inserted into the mounting plate 21, the positioning mechanism 3 performs initial positioning of the bending blade 22. The bending blade 22 presses against the positioning block 31, causing the positioning block 31 to move towards the locking block 28. The movement of the positioning block 31 drives the sliding rod 32 to move along the fixed rod 33. While the sliding rod 32 moves, it presses against the spring 34, putting the spring 34 in a compressed state. Then, after the slot opened by the bending blade 22 passes the positioning block 31, the spring 34 rebounds and causes the positioning block 31 to reset, making the positioning block 31 tightly fit against the inside of the slot, thus initially fixing the bending blade 22. Then, the movement of the moving plate 27 drives the locking block 28 to engage with the slot. While the locking block 28 moves, it presses against the positioning block 31, putting the spring 34 in a compressed state, and then the locking block 28 tightly fits against one side of the positioning block 31, thus completing the fixing of the bending blade 22.

[0023] Working principle: like Figures 1-4 As shown, in this utility model, when the bending blade 22 is inserted into the mounting plate 21, the positioning mechanism 3 performs initial positioning of the bending blade 22. The bending blade 22 presses against the positioning block 31, causing the positioning block 31 to move towards the locking block 28. The movement of the positioning block 31 drives the sliding rod 32 to move along the fixed rod 33. While the sliding rod 32 is moving, it presses against the spring 34, putting the spring 34 in a compressed state. Then, after the slot opened by the bending blade 22 passes the positioning block 31, the spring 34 rebounds, causing the positioning block 31 to return to its original position, so that the positioning block 31 fits tightly against the inside of the slot, thereby achieving the bending... The blade 22 is initially fixed. Then, by rotating the knob 23, the double-acting screw 24 is driven to rotate inside the bearing 25. Since the double-acting screw 24 is threadedly connected to the moving plate 27, the moving plate 27 moves in opposite directions or in the opposite direction as the double-acting screw 24 rotates. The moving plate 27 moves inside the slide groove 26, which drives the locking block 28 to move. Then, the moving plate 27 drives the locking block 28 to engage with the slot. As the locking block 28 moves, it presses the positioning block 31, so that the spring 34 is in a compressed state. Then, the locking block 28 and the positioning block 31 are tightly fitted together, thus completing the fixing of the folding blade 22.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
