Fluoroplastic pipe flanging tooling

Abstract

This utility model discloses a fluoroplastic pipe flanging fixture, relating to the field of flanging forming machine technology. The utility model includes a base and a steel pipe. A U-shaped support frame is movably arranged inside the base, with both ends of the U-shaped support frame penetrating the top of the base. By rotating a screw, the U-shaped support frame can slide along an adjustment groove, adjusting its position and height, thereby adjusting the axial height of the steel pipe. This allows the flanging fixture to be applicable to flanging fluoroplastic pipes of different diameters, enhancing its practicality. Clockwise rotation of the double-ended screw drives two I-shaped sliding blocks to move synchronously closer, driving a motor to rotate the flanging module. This allows the flanging module to approach the fluoroplastic pipe while slowly rotating, simultaneously flanging both ends of the fluoroplastic pipe through the two flanging modules. This improves flanging quality and efficiency, and the flanging operation can be completed by only one person, making it convenient and labor-saving.

Description

Technical Field

[0001] This utility model belongs to the technical field of flanging forming machines, and in particular relates to a flanging tool for fluoroplastic pipes. Background Technology

[0002] To achieve corrosion protection for pipelines, a PTFE (polytetrafluoroethylene) lining is typically installed on the inner wall of the steel pipe. Furthermore, a flange is formed at the pipe end. The flange is created by heating the exposed PTFE lining to soften it, then pressing it against the flange using a mold. After cooling and solidification, a fluoroplastic flange is formed, directly connected to the PTFE lining inside the steel pipe. Generally, a mold and a three-jaw puller are used to flange the fluoroplastic pipe, and the flangering operation must be performed sequentially at both ends of the steel pipe. This process is time-consuming, inefficient, and cumbersome, affecting the quality of the flange. A search revealed that patent application number 202420184741.9 discloses a fluoroplastic pipe flanging fixture, including a support base for supporting a steel pipe and a flanging module for pressing and shaping the end of the fluoroplastic pipe onto the end face of the steel pipe. The fixture is characterized in that: there are two support bases, which are arranged opposite to each other, and the steel pipe is horizontally supported by the two support bases. The support bases are equipped with push rod assemblies that push the flanging module to press the end of the fluoroplastic pipe to form a flanging. The installation height of the push rod assembly on the support base is adjustable.

[0003] However, in actual use, the applicant found that when flanging the fluoroplastic pipe, two people are required to drive the flanging modules on both sides toward the end of the fluoroplastic pipe and manually rotate the flanging modules on both sides. The operation is not convenient and labor-saving. Therefore, we propose a fluoroplastic pipe flanging fixture. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Both ends of the steel pipe rest on the ends of the U-shaped support frame, and a fluoroplastic tube is inserted through the steel pipe. A chamfered slide block is symmetrically slidably connected to the rear side of the base. A double-ended lead screw is rotatably connected to the base via bearings, with the threads at both ends of the double-ended lead screw rotating in opposite directions. Each end of the double-ended lead screw is threaded through the lower ends of two chamfered slide blocks. A motor is fixedly mounted on the outer wall of the upper end of each chamfered slide block, and the motor's transmission end penetrates the chamfered slide block and is coaxially fixedly connected to a flanging module.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A fluoroplastic pipe flanging fixture includes a base 1 and a steel pipe 3. A U-shaped support frame 2 is movably installed inside the base 1, and an adjustment groove 12 is opened inside the base 1. The lower part of the U-shaped support frame 2 slides along the side wall of the adjustment groove 12. A screw 8 is rotatably connected to the adjustment groove 12 via a bearing. The upper end of the screw 8 passes through the top of the base 1 and is fitted with an adjustment disc 81. The screw 8 is threaded through the middle of the U-shaped support frame 2. Both ends of the U-shaped support frame 2 pass through the top of the base 1. A Y-shaped through groove is opened at the upper end of the U-shaped support frame 2 for placing the fluoroplastic pipe. The two ends of the steel pipe 3 are respectively placed on the two ends of the U-shaped support frame 2, and the fluoroplastic pipe is inserted through the steel pipe 3. By rotating the screw 8, the U-shaped support frame 2 can be driven to slide along the adjustment groove 12, and the position and height of the U-shaped support frame 2 can be adjusted, thereby adjusting the axial height of the steel pipe 3. This makes the flanging fixture applicable to the flanging processing of fluoroplastic pipes of different diameters, and its practicality is enhanced.

[0022] A C-shaped slide block 4 is symmetrically slidably connected to the rear side of the base body 1. A guide groove 11 is horizontally opened on the rear side of the base body 1. A guide slider is provided at the lower part of the C-shaped slide block 4, and the guide slider slides along the guide groove 11. A double-ended lead screw 7 is rotatably connected to the base body 1 through a bearing. The threads at both ends of the double-ended lead screw 7 have opposite directions, and both ends of the double-ended lead screw 7 are threaded through the lower ends of the two C-shaped slide blocks 4, respectively. Both ends of the double-ended lead screw 7 are threaded through the guide sliders at the lower part of the two C-shaped slide blocks 4, respectively. One end of the double-ended lead screw 7 extends to the outside of the base body 1 and is fixedly installed. A hand crank 71 is used. A motor 5 is fixedly installed on the outer wall of the upper end of the C-shaped slide 4. The conveying end of the motor 5 passes through the C-shaped slide 4 and is coaxially fixedly connected to the flanging module 6. By rotating the double-headed screw 7 clockwise, the two C-shaped slides 4 move closer to each other synchronously, and drive the motor 5 to drive the flanging module 6 to rotate. This allows the flanging module 6 to move closer to the fluoroplastic tube while rotating slowly. By having the two flanging modules 6 simultaneously perform flanging processing on both ends of the fluoroplastic tube, the flanging quality and efficiency can be improved. Moreover, only one person is needed to complete the flanging operation, which is convenient and labor-saving.

[0023] Working principle: Before flanging, the heated and softened fluoroplastic tube is pulled into the steel pipe 3. 20-50mm long sections of fluoroplastic tube are left at both ends of the steel pipe 3 for flanging. After the fluoroplastic tube cools, the steel pipe 3 is supported on the U-shaped support frame 2. Rotating the adjusting disc 81 drives the screw 8 to rotate. The rotation of the screw 8 causes the U-shaped support frame 2 to slide along the adjusting groove 12, moving the steel pipe 3 vertically until its axis is basically aligned with the axis of the flanging module 6. Then, the sections of fluoroplastic tube left at the ends of the steel pipe 3 are... The fluoroplastic tube is heated to soften it to the point where it can be flanged. Then, the hand crank 71 is manually turned along the needle to drive the double-ended lead screw 7 to rotate. The rotation of the double-ended lead screw 7 can drive the two C-shaped slide blocks 4 to move synchronously closer along the guide slide groove 11. At the same time, the drive motor 5 drives the flanging module 6 to rotate, so that the flanging module 6 moves towards the end of the fluoroplastic tube to fold the end of the fluoroplastic tube until the flanging module 6 is pressed against the end face of the steel pipe 3. After the folded part cools down, the flanging module 6 is released to complete the flanging operation.
