Description

Technical Field

[0001] This utility model belongs to the field of polytetrafluoroethylene (PTFE) pipe technology, and specifically relates to a PTFE pipe cutting device. Background Technology

[0002] Polytetrafluoroethylene (PTFE) pipe, also known as Teflon pipe, F4 pipe, or PTFE tube, is a high-performance piping material. PTFE pipe has a wide operating temperature range, from -60℃ to +260℃, with some sources indicating an upper limit of +250℃ or +260℃. Within this temperature range, its mechanical properties change very little. It exhibits excellent corrosion resistance, being resistant to all strong acids, alkalis, oxidants, and various organic solvents. It also boasts a low coefficient of friction, making it a good friction-reducing and self-lubricating material, with a static friction coefficient lower than its dynamic friction coefficient. Currently, PTFE pipes need to be cut according to assembly dimensions during installation at construction sites. However, current cutting methods often involve on-site cutting with a blade, which is unstable and results in aesthetically unappealing cuts with skewed edges. Therefore, the inventor has proposed a PTFE pipe cutting device. Utility Model Content

[0023] This specific embodiment is a polytetrafluoroethylene (PTFE) tube cutting device, the structural schematic diagram of which is shown below. Figure 1 , Figure 2 As shown, the system includes a support base 1, a lifting plate 2, a cutting disc 7, and a lifting plate 5. A support beam 4 is fixed to the upper surface of the support base 1. The lifting plate 2 is positioned above the support beam 4, and a lifting column 3 is fixedly connected to the bottom of the lifting plate 2. The lifting column 3 is vertically positioned and slides into the support beam 4. A limiting rod 8 protrudes from the upper surface of the support base 1. The limiting rods 8 are spaced apart in pairs, with gaps between them for installing polytetrafluoroethylene (PTFE) tubes. A pressure plate 17 is provided at each gap, and the pressure plate 17 slides into the gap. The lifting plate 5 has an installation groove 10 in its center, and the cutting disc 7 is fixed inside the installation groove 10. A drive motor 6 is fixed to the outer wall of the lifting plate 5, and the drive motor 6 is connected to the cutting disc 7. A sliding groove 18 is vertically opened on the inner side wall of the support beam 4. The bottom of the lifting column 3 passes through the sliding groove 18. A slider 9 protrudes from the end of the lifting plate 5 and is adapted to slide in the sliding groove 18. The bottom of the lifting column 3 is fixedly connected to the sliding groove 18. The support base 1 has a cutting groove at its center, and the cutting disc 7 corresponds to the cutting groove.

[0024] Reference Figure 3The upper surface of the lifting plate 2 is provided with a handle 15, and a movable rod 13 is fixedly fixed at the center of the bottom end of the lifting plate 2. A spring 12 is fixedly connected to the end of the movable rod 13 away from the lifting plate 2. A fixed column 14 is slidably sleeved at the bottom of the movable rod 13. The fixed column 14 is fixedly embedded in the upper surface of the support beam 4, and the interior of the fixed column 14 is a hollow structure. A spring 12 is fixedly connected to the end of the movable rod 13 that slides into the fixed column 14. The spring 12 is vertically arranged, and the end away from the movable rod 13 is fixedly connected to the inner wall of the fixed column 14.

[0025] Reference Figure 4 The inner wall of the limiting rod 8 is vertically provided with a lifting groove. The end of the pressure plate 17 slides along the lifting groove. The end of the pressure plate 17 is vertically threaded with an adjusting screw 16, which is rotatably connected to the bottom end face of the lifting groove.

[0026] Working principle: In use, first place the PTFE tube to be cut between the limiting rods 8. The limiting rods 8 can accommodate multiple PTFE tubes at the same time. After aligning the position of the PTFE tube to be cut with the cutting disc 7, rotate the adjusting screw 16. The pressure plate 17 moves downward under force, pressing the PTFE tube tightly. Two sets of pressure plates 17 are symmetrically arranged on the support base 1, pressing the part to be cut and the uncut part respectively. Then press the handle 15. The handle 15 drives the lifting rod to move downward. The lifting rod slides along the support beam 4 and drives the lifting plate 5 to descend synchronously, raising the tube. As plate 2 descends, it applies pressure to moving rod 13, causing moving rod 13 to move towards the interior of fixed column 14. Spring 12 is compressed under force. As lifting plate 5 moves downward, cutting disc 7 approaches the cutting groove and contacts the PTFE tube to cut it. Then, the grip rod 15 is released, spring 12 elastically returns to its original position, and moving rod 13 upward, thereby lifting plate 2 upward. The sliding rod 11 drives lifting plate 5 to move upward synchronously. At this time, cutting disc 7 can move upward away from PTFE tube. After adjusting PTFE tube to a new cutting position, lifting plate 2 can be pressed again to perform cutting operations.
