[0002] A cutting device is a specialized piece of equipment used for the precise cutting and processing of various materials. Its main function is to cut raw materials into specific shapes and sizes so that they can be processed into the required parts. This device plays a vital role in the manufacturing industry, especially in the field of metal processing. Hydraulic cutting, as an efficient cutting method, is widely used in the cutting process of metal materials. Hydraulic cutting equipment usually uses high-pressure oil to drive the cutting blade.

[0015] (III) Beneficial Effects
[0016] This utility model has a simple structure and is easy to use. By setting up a clamping mechanism, the second electric push rod is activated, and its movable end pushes the connecting block to move, which in turn causes the control rod to move. Since the control rod is fixedly installed between the two rotating rings, the movement of the control rod will cause the rotating rings to rotate. The rotation of the rotating rings will further drive the second connecting plate to move. Subsequently, the second connecting plate drives the clamping rod to move synchronously toward the center of the fixed ring, thereby achieving the clamping and fixing of the bushing. This not only improves the accuracy of cutting the bushing, but also effectively reduces the waste of production materials. Attached Figure Description

Detailed Implementation
[0024] 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.
[0025] This utility model provides a cutting device, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the cutting device includes a base plate 1, a first electric push rod 2 fixedly mounted on the base plate 1, a cutting box 3 fixedly mounted on the movable end of the first electric push rod 2, and a clamping mechanism disposed inside the cutting box 3 for clamping the bushing.
[0026] The clamping mechanism includes a support block 4 fixedly installed on the inner wall of the bottom of the cutting box 3, a fixing ring 5 fixedly installed on the top of the support block 4, a first connecting plate 6 rotatably installed on one side of the fixing ring 5, a rotating ring 7 rotatably installed on the side surface of the fixing ring 5, a second connecting plate 8 rotatably installed on one side of the rotating ring 7, a clamping rod 9 fixedly installed inside the second connecting plate 8, a control rod 10 fixedly installed between the two rotating rings 7, a second electric push rod 11 hinged to the inner wall of the bottom of the cutting box 3, and a connecting block 12 fixedly installed on the movable end of the second electric push rod 11.
[0027] Multiple first connecting plates 6 are provided, and the first connecting plates 6 are arranged in a ring array on the fixing ring 5. The end of the clamping rod 9 away from the second connecting plate 8 passes through the first connecting plate 6.
[0028] The end of the clamping rod 9 away from the second connecting plate 8 is slidably connected to the inside of the first connecting plate 6, and the connecting block 12 is slidably connected to the side surface of the control rod 10.
[0029] When using this cutting device, first place the base plate 1 in a suitable position, then place the bushing to be cut inside the fixing ring 5, and start the second electric push rod 11. The movable end of the second electric push rod 11 pushes the connecting block 12 to move, and the connecting block 12 drives the control rod 10 to move. Since the control rod 10 is fixedly installed between the two rotating rings 7, the movement of the control rod 10 will drive the rotating rings 7 to rotate. When the rotating rings 7 rotate, they will drive the second connecting plate 8 to move, and the second connecting plate 8 will drive the clamping rod 9 to move. Since the end of the clamping rod 9 away from the second connecting plate 8 is slidably connected to the inside of the first connecting plate 6, multiple clamping rods 9 will move towards the center of the fixing ring 5 at the same time to clamp and fix the bushing. After cutting, the second electric push rod 11 is reset, the clamping rod 9 releases the bushing, and the cut bushing can be taken out. At the same time, the movable end of the first electric push rod 2 pushes the cutting box 3 to rise and fall, so as to adapt to the use of different users, realize the rapid clamping and cutting of the bushing, and improve the cutting efficiency and cutting quality.
[0030] In order to cut the bushing, such as Figure 1 , Figure 2 and Figure 4 As shown, a third electric push rod 13 is fixedly connected to the top of the cutting box 3. The movable end of the third electric push rod 13 passes through the top of the cutting box 3, and a protective cover 14 is fixedly connected to the movable end of the third electric push rod 13.
[0031] A cutting blade 15 is rotatably connected inside the protective cover 14, and a motor 16 is fixedly connected to one side of the protective cover 14. The output end of the motor 16 passes through the protective cover 14 and is fixedly connected to one side of the cutting blade 15.
[0032] When the cutting device is in use, the motor 16 is started, and the motor 16 drives the cutting blade 15 to rotate inside the protective cover 14 to cut the bushing. At the same time, the movable end of the third electric push rod 13 pushes the protective cover 14 and the cutting blade 15 down, so that the cutting blade 15 contacts the bushing to perform the cutting operation. After the cutting is completed, the third electric push rod 13 is reset, driving the protective cover 14 and the cutting blade 15 to rise and move away from the bushing, avoiding unnecessary damage to the bushing and improving the cutting efficiency and cutting quality of the bushing.
[0033] Furthermore, to facilitate the collection of the cut debris, such as... Figure 1 and Figure 2 As shown, a receiving frame 17 is fixedly connected to the bottom of the cutting box 3, and a receiving box 18 is slidably connected inside the receiving frame 17. The receiving box 18 is located directly below the cutting blade 15.
[0034] When the cutting device is in use, the motor 16 is started to perform the cutting operation. The cut debris will fall directly into the receiving box 18 inside the receiving frame 17. When the debris in the receiving box 18 accumulates to a certain amount, the user can directly pull out the receiving box 18 to dispose of the debris in a unified manner. This is convenient and quick, and avoids debris scattering all over the ground, keeping the working environment clean. In addition, the sliding connection between the receiving frame 17 and the receiving box 18 makes the replacement and cleaning of the receiving box 18 very simple, greatly improving work efficiency.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
