[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0014] Depend on Figures 1 to 4 It is known that a clamping device for cutting plastic pipes includes a base plate 1, on which a first support 2 and a second support 3 are provided. The upper part of the first support 2 and the second support 3 is a concave arc-shaped structure. Multiple first rollers 4 are provided at the upper end of the first support 2 and the second support 3. The first rollers 4 at the bottom are drive wheels 5. A cover plate 6 is lifted and lowered on the top of the first support 2 and the second support 3. The cover plate 6 is an upwardly convex arc-shaped structure. A second roller 7 is provided at the bottom of the cover plate 6. The plastic pipe is placed on the first support 2 and the second support 3 and pressed and fixed by the cover plate 6.
[0015] In practical use, this utility model
[0016] The plastic pipe is placed on the first support 2 and the second support 3. The cover plate 6 is lowered to press the plastic pipe. The equipment is started and the drive wheel 5 rotates to drive the plastic pipe to rotate. In this way, the plastic pipe can be cut without moving the cutter. Moreover, there is no need to adjust the position of the plastic pipe. The cutting can be completed in one go. The cutting position is accurate and the cutting efficiency is high.
[0017] A common cutter can be used, which can achieve simple displacement. As the plastic tube rotates, the cutter approaches the plastic tube and gradually cuts it, ultimately achieving the cutting of large-diameter plastic tubes.
[0018] The lower part of the plastic pipe is supported by the first roller 4, and the top is in contact with the second roller 7. When rotating, the first roller 4 and the second roller 7 can greatly reduce the friction and ensure the rotation of the plastic pipe. At the same time, the first roller 4 and the second roller 7 have a certain width and have a limiting effect in the axial direction of the plastic pipe to prevent the plastic pipe from undergoing axial displacement.
[0019] A rotating shaft 8 is inserted inside the first bracket 2 and the second bracket 3. The rotating shaft 8 is connected to the drive wheel 5. A motor 9 connected to the rotating shaft 8 is fixed on the first bracket 2. The motor 9 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the drive wheel 5 to rotate, thereby causing the plastic pipe placed on the first bracket 2 and the second bracket 3 to rotate.
[0020] Hydraulic cylinders 10 are provided on the sides of the first support 2 and the second support 3. The telescopic rod of the hydraulic cylinder 10 is connected to the cover plate 6, forming a structure in which the hydraulic cylinder 10 controls the lifting and lowering of the cover plate 6. When placing and removing plastic pipes, the cover plate 6 is raised, allowing the plastic pipes to enter and be removed smoothly. During the cutting process, the hydraulic cylinder 10 retracts, causing the cover plate 6 to press the plastic pipes tightly, preventing the plastic pipes from shifting and affecting the cutting accuracy.
[0021] The outer sides of the first roller 4 and the second roller 7 are both covered with flexible rubber. When the first roller 4 and the second roller 7 come into contact with the plastic tube, the flexible rubber acts as a buffer and can prevent the plastic tube from axially displacing, thus limiting its axial movement. In addition, the flexible rubber can increase the contact area between the roller 4 and the plastic tube, allowing it to rotate better.
[0022] When cutting, you can choose a suitable cutting position according to the actual situation. It is best to cut outside the first support 2 or the second support 3 to ensure the support of the plastic pipe by the first support 2 and the second support 3, and avoid radial displacement of the plastic pipe that would affect the cutting effect. The cutting position should be close to the first support 2 or the second support 3 to provide better support.
[0023] Compared with the prior art, this utility model has the following advantages: it can clamp the plastic pipe in all directions and rotate the plastic pipe, thus facilitating its cutting. It can complete the one-time cutting and shaping without moving the plastic pipe, improving cutting efficiency and ensuring cutting accuracy.
