Description

Technical Field

[0001] The utility model relates to the technical field of polypropylene graphite tube processing, in particular to a clamping device for polypropylene graphite tube processing. Background Art

[0002] Graphite tube is a tube made of graphite as the main raw material, which has good corrosion resistance and good heat transfer, but graphite is easy to crack, and has low bending and tensile strength, and low pressure resistance. Polypropylene is a thermoplastic synthetic resin with excellent performance. It is a colorless, translucent, thermoplastic, lightweight general-purpose plastic with chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high-wear processing performance. This has made polypropylene rapidly developed and applied in many fields such as machinery, automobiles, electronic appliances, construction, textiles, packaging, agriculture, forestry, fishery and food industry since its advent. The graphite tube modified by polypropylene is a polypropylene graphite tube, which has high strength, excellent heat transfer performance, and strong corrosion resistance, which can increase the scope of use and service life of the graphite tube.

[0003] Patent No. CN213828718U discloses a clamping device for processing corrugated pipes, which includes two bottom plates, and four pulleys are fixedly mounted on the bottom of the bottom plates. The clamping device for processing the bellows is convenient for the rotating screw to rotate inside the support box through the rotating motor and the rotating bearing, and the lifting shaft is lifted and lowered outside the supporting box through the rotation of the rotating screw, so that the height of the clamping box is driven by the connecting rod, and then the clamping height of the bellows is adjusted according to the use requirements. The transmission screw rotates inside the clamping box through the transmission motor and the transmission bearing, and the two movable shafts move toward the opposite or separated side through the rotation of the transmission screw, so that the clamping plate is driven to move by the extension rod, and then the two clamping plates are used to clamp and fix the main body of the bellows, and the bottom plate is moved by the pulley, so that the clamping spacing is adjusted according to the length of the bellows, and the purpose of convenient use is achieved. The clamping device of the above scheme is also suitable for the processing and clamping of polypropylene graphite tubes. Since no translation component is set, it is not convenient to translate the polypropylene graphite tube when processing the polypropylene graphite tube, which is not convenient for the actual processing of the polypropylene graphite tube, and affects the reinforcement efficiency of the polypropylene graphite tube. To this end, we propose a clamping device for processing polypropylene graphite tubes. Utility Model Content

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-3 As shown, a clamping device for processing polypropylene graphite tubes includes a bottom plate 1 and two groups of bottom plates 1 are used together to process and clamp the polypropylene graphite tubes, and also includes a clamping plate 2 arranged above the bottom plate 1 for clamping, the inner wall of the clamping plate 2 is installed with equidistant pulleys 4 for translating the polypropylene graphite tube, the inner wall of the clamping plate 2 is opened with equidistant mounting grooves 3, the mounting grooves 3 are movably connected to the pulleys 4, the end surface of the pulley 4 close to the inner side of the clamping plate 2 is flush with the inner wall of the clamping plate 2, and the outer wall of the clamping plate 2 is welded to the side of the pulley 4 A limit plate 5 is provided, and a bolt 6 for limiting the pulley 4 is threadedly connected to the side surface of the limit plate 5; a mounting groove 3 is provided on the surface of the clamping plate 2 to install the pulley 4. When processing the polypropylene graphite tube, with the support of the pulley 4, it is convenient to support the polypropylene graphite tube to move horizontally in the clamping plate 2, and then it is convenient to process different positions on the surface of the polypropylene graphite tube, thereby increasing the processing efficiency of the polypropylene graphite tube. At the same time, the bolt 6 is used to limit the pulley 4, so as to facilitate the limiting effect of the pulley 4 after supporting the movement of the polypropylene graphite tube.

[0018] Among them, a retractable and movable disc 9 for reinforcement is installed on the side of the base plate 1, a symmetrical fixed plate 10 is welded at the bottom of the base plate 1, a movable plate 8 is inserted on the side of the fixed plate 10, and a disc 9 that can be raised and lowered is installed under the movable plate 8. A screw 7 is threadedly connected to the outer end of the upper surface of the movable plate 8, and the bottom of the screw 7 is fixedly connected to the disc 9; after the clamping plates 2 of the two groups of base plates 1 clamp the polypropylene graphite tube, the movable plate 8 is pulled out and the screw 7 is rotated to make the disc 9 contact with the working plane, which reinforces the device and prevents the center of gravity of the device from shifting after the polypropylene graphite tube is clamped, thereby preventing the stability of the device from being affected.

[0019] It should be noted that the utility model is a clamping device for processing polypropylene graphite tubes. When working, firstly, the movable plate 8 is pulled out and the screw rod 7 is rotated to make the disc 9 contact with the working plane, so as to reinforce the device and prevent the center of gravity of the device from shifting after the polypropylene graphite tube is clamped, thereby affecting the stability of the device. Then, the polypropylene graphite tube is placed between the two groups of clamping plates 2, and the clamping plates 2 are controlled to clamp and fix the polypropylene graphite tube (the movement control of the clamping plates 2 has been disclosed in patent number CN213828718U). When processing the polypropylene graphite tube, the rotation restriction of the pulley 4 can be released by loosening the bolt 6, because the end face of the pulley 4 close to the inner side of the clamping plate 2 is flush with the inner wall of the clamping plate 2, so the pulley 4 can support the translation of the polypropylene graphite tube, thereby facilitating the processing of different positions on the surface of the polypropylene graphite tube, thereby increasing the processing efficiency of the polypropylene graphite tube, and the rotation restriction of the pulley 4 can be restored by tightening the bolt 6 after adjustment, which is convenient to operate.
