Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a steel-lined polytetrafluoroethylene pipe processing device. Background Technology

[0002] Due to their excellent temperature resistance and corrosion resistance, steel-lined polytetrafluoroethylene (PTFE) pipes are widely used in various fields such as chemical, pharmaceutical, metallurgical, and food industries. The current processing of steel-lined PTFE pipes requires flanging equipment, cutting equipment, welding equipment, forming equipment, and testing and inspection equipment, etc. Flanging is an important process for steel-lined PTFE pipes. The main purpose of flanging is to turn up one end of the pipe and press it into a fixed angle to enhance the pipe's sealing and stability.

[0003] Existing flanging equipment for processing PTFE-lined steel pipes typically includes a cylinder, an extrusion plate, a base, and two support frames. The cylinder and support frames are all mounted on the base. During operation, the PTFE-lined steel pipe is placed on the support frames, and one side of the pipe is manually heated using a torch. After heating, the extrusion plate is manually held to contact the heated side of the pipe, and the cylinder pushes the extrusion plate to press against the heated side of the pipe, completing the flanging process. However, in the use of existing equipment, due to the varying pipe specifications and the fixed position of the cylinder, the pressure point during extrusion is offset when the pipe is small, potentially leading to uneven force distribution and affecting the overall flanging quality. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steel-lined polytetrafluoroethylene pipe processing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel-lined polytetrafluoroethylene (PTFE) pipe processing device, which is installed on a base and includes a pushing component, a support frame one, and a support frame two. Two support frames one are provided, both fixedly mounted on the base. The support frame two is disposed between the two support frames one and movably mounted in an installation groove provided on the base.

The pushing component is connected to the base through the adjusting component.

[0006] The adjustment component includes a fixed block, a threaded rod, and a positioning block. There are two positioning blocks, which are fixedly disposed on opposite sides of the push component. The two positioning blocks are movably disposed in two positioning slots provided inside the base. The fixed block is fixedly disposed on the side of the push component near the two positioning blocks. One end of the threaded rod passes through the fixed block.

[0007] Preferably, the bottom of the plurality of limiting groups is provided with a pull plate, and the bottoms of the plurality of limiting groups are connected by the pull plate.

[0008] Preferably, the limiting assembly includes a limiting rod and a limiting disc. One end of the limiting rod is fixedly connected to one side of the pulling plate, and the end of the limiting rod away from the pulling plate passes through the support plate. A spring is provided on the outer wall of the limiting rod near the support plate. One end of the spring is fixedly connected to one side of the pulling plate, and the end of the spring away from the pulling plate is fixedly connected to one side of the support plate. The end of the limiting rod near the spring is fixedly connected to one end of the limiting disc. The support plate is provided with a connecting groove that allows the limiting disc to enter. The end of the limiting disc away from the connecting groove extends into the interior of the connecting rod.

[0009] Preferably, two sliding rods are installed inside the mounting slot, and both sliding rods pass through the support frame 2.

[0014] Compared with existing technologies, this steel-lined PTFE pipe processing device, by setting up a fixed block, a threaded rod, and a positioning block, allows for adjustment of the vertical position of the pushing component by rotating the threaded rod, which passes through the fixed block and is fixedly connected to one side of the fixed block. The two positioning blocks ensure the smooth movement of the pushing component. Adjusting the position of the pushing component allows the pressure point to be closer to the center of the pipe when processing smaller pipes, resulting in more uniform force and better overall flanging quality.

[0015] Compared with existing technologies, this steel-lined polytetrafluoroethylene pipe processing device, by setting up a second support frame, allows for adjustments to the position of the second support frame when the pipe length is short and less than the distance between the two first support frames. The adjusted position of the second support frame is then limited by a limiting group, making it adaptable to pipes of different lengths and increasing the versatility of the overall equipment.

Detailed Implementation

[0023] Reference Figure 1-5 This utility model provides a steel-lined polytetrafluoroethylene pipe processing device. The device is installed on a base 1 and includes a pushing component, a support frame 1 7, and a support frame 2 8. There are two support frames 1 7, both of which are fixedly installed on the base 1. The support frame 2 8 is located between the two support frames 1 7 and is movably installed in an installation groove provided on the base 1. A connecting rod 10 is provided on one side of the support frame 2 8 and is movably installed in a sliding groove provided on one side of the base 1. A support plate 11 is also provided on one side of the base 1. The support plate 11 is provided with multiple limiting groups for limiting the connecting rod 10. The pushing component is located on one side of one of the support frames 1 7 and an adjusting component is provided at the bottom of the pushing component. The pushing component is connected to the base 1 through the adjusting component.

[0024] The adjustment assembly includes a fixed block 6, a threaded rod 19, and a positioning block 13. There are two positioning blocks 13, which are fixedly installed on opposite sides of the push assembly. The two positioning blocks 13 are movably installed in two positioning slots 17 inside the base 1.

One end of the threaded rod 19 passes through the fixed block 6, and the upper end of the threaded rod 19 is fixedly connected to a rotating disk 5.

[0025] Specifically, by setting a fixed block 6, a threaded rod 19, and a positioning block 13, the vertical position of the pushing component can be adjusted by rotating the threaded rod 19, since the threaded rod 19 passes through the fixed block 6 and one side of the fixed block 6 is fixedly connected to the pushing component. By setting two positioning blocks 13, the smoothness of the movement of the pushing component can be ensured. By adjusting the position of the pushing component, when processing smaller pipes, the pressure point of the extrusion can be adjusted to the center of the pipe, resulting in uniform force and better overall flanging quality.

[0026] The bottom of multiple limit groups is provided with a pull plate 9, and the bottoms of the multiple limit groups are connected by the pull plate 9. The limit group includes a limit rod 15 and a limit plate 14. One end of the limit rod 15 is fixedly connected to one side of the pull plate 9, and the end of the limit rod 15 away from the pull plate 9 passes through the support plate 11. A spring 16 is provided near the outer wall of the support plate 11 of the limit rod 15. One end of the spring 16 is fixedly connected to one side of the pull plate 9, and the end of the spring 16 away from the pull plate 9 is fixedly connected to one side of the support plate 11. The end of the limit rod 15 near the spring 16 is fixedly connected to one end of the limit plate 14. The support plate 11 is provided with a connecting groove for the limit plate 14 to enter. The end of the limit plate 14 away from the connecting groove extends into the interior of the connecting rod 10. Two sliding rods 18 are installed inside the mounting groove, and both sliding rods 18 pass through the support frame 8.

[0027] By moving the pull plate 9 to the bottom, the limit plate 14 is disengaged from the connecting rod 10. At this time, the position of the connecting rod 10 can be adjusted, that is, the position of the support frame 8 can be adjusted. After adjusting to the appropriate position, by releasing the pull plate 9, the limit plate 14 is moved into the interior of the connecting rod 10 by the force of the spring 16, thus completing the adjustment and limiting of the position of the connecting rod 10. When the length of the pipe is short and lower than the distance between the two support frames 7, the position of the support frame 8 can be adjusted to accommodate pipes of different lengths, making the overall equipment more versatile.

[0028] The pushing component includes a support block 4, a cylinder 3, a pressing plate 2, and a movable plate 20. The upper end of the movable plate 20 is fixedly connected to the bottom end of the support block 4. The cylinder 3 is fixedly mounted on the support block 4. The output end of the cylinder 3 is fixedly connected to one side of the pressing plate 2. A plurality of pulleys 12 are provided on one side of the pressing plate 2. A rotating rod 21 passes through the plurality of pulleys 12. The plurality of pulleys 12 are respectively set in a plurality of wheel grooves provided on the movable plate 20.

[0029] Specifically, during use, the steel-lined PTFE pipe can be placed on two support frames. Then, one side of the steel-lined PTFE pipe is heated manually using a torch. After heating, the extrusion plate 2 is manually supported to contact the heated side of the steel-lined PTFE pipe. The cylinder 3 pushes the extrusion plate 2 to extrude the heated side of the steel-lined PTFE pipe, completing the flanging process. The pulley 12 is set to ensure the stability of the extrusion plate 2 during the movement.

[0030] Working principle: When using this equipment, the steel-lined PTFE pipe can be placed on two support frames. Then, one side of the steel-lined PTFE pipe is heated manually with a torch. After heating, the extrusion plate 2 is manually supported to contact the heated side of the steel-lined PTFE pipe. The cylinder 3 pushes the extrusion plate 2 to extrude the heated side of the steel-lined PTFE pipe, completing the flanging process. The pulley 12 is set to ensure the stability of the extrusion plate 2 during the movement.

[0031] By setting a fixed block 6, a threaded rod 19, and a positioning block 13, the vertical position of the pushing component can be adjusted by rotating the threaded rod 19, since the threaded rod 19 passes through the fixed block 6 and one side of the fixed block 6 is fixedly connected to the pushing component. By setting two positioning blocks 13, the smoothness of the movement of the pushing component can be ensured. By adjusting the position of the pushing component, when processing smaller pipes, the pressure point of the extrusion can be adjusted to the center of the pipe, resulting in uniform force and better overall flanging quality.

[0032] By moving the pull plate 9 to the bottom, the limit plate 14 is disengaged from the connecting rod 10. At this time, the position of the connecting rod 10 can be adjusted, that is, the position of the second support frame 8 can be adjusted. After adjusting to the appropriate position, by releasing the pull plate 9, the limit plate 14 is moved into the interior of the connecting rod 10 by the force of the spring 16, thus completing the adjustment and limiting of the position of the connecting rod 10. When the length of the pipe is short and lower than the distance between the two support frames 7, the position of the second support frame 8 can be adjusted to accommodate pipes of different lengths, making the overall equipment more versatile.
