Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing technology, and in particular to a pipe fitting traction machine. Background Technology

[0002] Teflon tubing is a high-performance pipe made primarily of polytetrafluoroethylene (PTFE). It possesses excellent high-temperature resistance, corrosion resistance, a low coefficient of friction, and good electrical insulation properties, making it widely used in chemical, electronics, medical, and aerospace industries. In the production process of Teflon tubing, the traction process is crucial for ensuring continuous extrusion, dimensional stability, and surface quality. The traction machine, as a key piece of equipment in this process, directly impacts the consistency of the final product's quality.

[0003] Existing Teflon tube traction machines typically employ one or more pairs of traction tracks or clamping rollers, driven synchronously by a power unit to apply a constant tension to the continuously extruded tubes for stable traction. Such devices can meet basic traction requirements in practical applications and can be integrated with a speed regulation system to achieve continuous operation at different linear speeds.

[0004] However, existing traction machines mostly require manual adjustment of the spacing between the traction tracks or clamping rollers when clamping Teflon tubes of different outer diameters to accommodate changes in tube size. This adjustment process typically involves the disassembly and repositioning of multiple fasteners, and the operation steps are relatively fixed. This limits the flexibility of size adaptation when dealing with multiple batches of small-volume products with different specifications. Therefore, it is necessary to develop a newer technological design to solve these problems. Utility Model Content

[0035] Furthermore, in this application, the technical features described in an open-ended manner include both closed technical solutions composed of the listed features and open technical solutions that include the listed features.

[0036] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings: like Figure 1-7 As shown, the pipe fitting traction machine includes a frame 1, on which a mounting plate 2 is fixedly connected. The mounting plate 2 has a first clamping component 3 and a second clamping component 4 for clamping pipe fittings. A spacing adjustment component 5 is provided between the first clamping component 3 and the second clamping component 4 and the mounting plate 2 to adjust the distance between them. In this embodiment, the positions of the first clamping component 1 and the second clamping component 2 are adjusted by the spacing adjustment component, enabling them to pull pipe fittings of different specifications. This effectively solves the problem of disassembling and positioning multiple fasteners when clamping Teflon pipes of different outer diameters. Of course, it is not limited to this; other devices capable of adjusting the positions of the first clamping component 1 and the second clamping component 2 can also be used.

[0037] Specifically, such as Figure 4 As shown, the spacing adjustment assembly 5 includes a lead screw 51 and a transmission block 52. A screwing part 511 for rotating the lead screw 51 is provided at its end. The transmission block 52 is connected to the lead screw 51, and two transmission blocks 52 are provided. The transmission blocks 52 are fixedly connected to clamping assembly one 3 and clamping assembly two 4. In this embodiment, the lead screw is fixed to the mounting plate by two bearing seats and bearings. Tightening the screwing part drives the lead screw to rotate, which in turn drives the transmission block, which in turn drives clamping assembly one and clamping assembly two to move. However, this is not limited to this; any other component capable of driving clamping assembly one and clamping assembly two to move can be used.

[0038] Specifically, such as Figure 5 , 6As shown, the lead screw 51 has a first threaded section 512 and a second threaded section 513, with opposite directions of rotation. In this embodiment, by setting the first and second threaded sections to have opposite directions of rotation, the two transmission blocks can move in opposite directions along the direction of the lead screw, thereby causing the clamping assembly one and the clamping assembly two to move in opposite directions along the direction of the lead screw, thus enabling the clamping assembly one and the clamping assembly two to adapt to pipe fittings of different specifications. Of course, this is not limited to this; any other mechanism that enables the clamping assembly one and the clamping assembly two to move in opposite directions along the direction of the lead screw can be used.

[0039] Specifically, the spacing adjustment component 5 also includes a sliding block 53 and a sliding guide rail 54. The sliding guide rail 54 is fixedly connected to the mounting plate 2, and the sliding block 53 is slidably connected to the sliding guide rail 54. The sliding block 53 is fixedly connected to the clamping component 1 3 and the clamping component 2 4. In this embodiment, two sliding guide rails are provided on both sides of the lead screw, and four sliding blocks are provided. Two sliding blocks are fixedly connected to the clamping component 1, and the other two sliding blocks are fixedly connected to the clamping component 2. The cooperation between the sliding blocks and the sliding guide rails strictly limits the movement of the clamping component 1 and the clamping component 2 to a straight line along the length of the sliding guide rail, increasing the smoothness and accuracy of the adjustment process. Of course, it is not limited to this; other components that can increase the smoothness and accuracy of the adjustment process can be used.

[0040] Specifically, such as Figure 7 As shown, a guide rail clamp 6 is also provided on the sliding guide rail 54. The guide rail clamp 6 matches the sliding block 53, and the guide rail clamp 6 is slidably connected to the sliding guide rail 54. The guide rail clamp 6 is fixedly connected to the clamping component 3 and the clamping component 4. In this embodiment, the guide rail clamp can lock the sliding block to restrict the sliding of the sliding block on the sliding guide rail, thereby restricting the movement of the clamping component 1 and the clamping component 2. Of course, it is not limited to this; other clamping components that can restrict the movement of the clamping component 1 and the clamping component 2 can also be used.

[0041] Specifically, the guide rail clamp 6 includes a tightening screw 61, a locking base 62, and clamping blocks 63. The locking base 62 is slidably connected to the sliding guide rail 54. The locking base 62 has a cavity for accommodating the clamping blocks 63. Two clamping blocks 63 are provided and disposed within the cavity. The tightening screw 61 is connected to the locking base 62 and the clamping blocks 63. In this embodiment, the locking base and the two clamping blocks have threaded holes for the tightening screw. By tightening the tightening screw, the two clamping blocks move inward along the tightening screw within the locking base, thus clamping the sliding guide rail and restricting the movement of the sliding blocks. Of course, this is not limited to this; other devices capable of restricting the movement of the sliding blocks can be used.

[0042] Specifically, a tensioning lever 611 is provided at the end of the tensioning screw 61. In this embodiment, the tensioning lever facilitates the operator in loosening or tightening the tensioning screw. Of course, it is not limited to this; any other mechanism that facilitates the operator in loosening or tightening the tensioning screw can be used.

[0043] Specifically, such as Figure 1 As shown, both clamping assembly 3 and clamping assembly 4 include a clamping fixing plate 31, a driving wheel 32, a driven wheel 33, a drive source 34, and a transmission belt 35. The sliding block 53, locking base 62, and transmission block 52 are all fixedly connected to the clamping fixing plate 31. The driving wheel 32 and driven wheel 33 are both mounted on the clamping fixing plate 31, and the transmission belt 35 is mounted on the driving wheel 32 and driven wheel 33. The drive source 34 is connected to the driving wheel 32 and is used to drive the driving wheel 32 to rotate. In this embodiment, the drive source is a servo motor, which drives the driving wheel to rotate. The driving wheel drives the driven wheel to rotate via the transmission belt. The transmission belts of clamping assembly 1 and clamping assembly 2 achieve the clamping and traction of the pipe fitting. Of course, this is not limited to this; other components capable of clamping and traction of pipe fittings can be used.

[0044] Specifically, such as Figure 2 As shown, a "V"-shaped groove 351 is provided on the transmission belt 35. In this embodiment, the "V"-shaped groove facilitates the transmission belt to clamp the pipe fitting. Of course, it is not limited to this, and other shapes or structures that facilitate the transmission belt to clamp the pipe fitting can be used.

[0045] Specifically, protective plates 7 are provided on the driving wheel 32 and the driven wheel 33, and the drive source 34 is fixedly connected to the protective plates 7. In this embodiment, the protective plates effectively protect the driving wheel and the driven wheel, and also facilitate the fixing of the drive source. Of course, other protective plates that can achieve the same function can also be used.

[0046] Working principle: During operation, the operator rotates the screw to rotate the lead screw, causing clamping assembly one and clamping assembly two to move in opposite directions along the lead screw. After adjusting the distance between clamping assembly one and clamping assembly two according to the pipe diameter, the operator rotates the tension lever to rotate the tension screw, causing the clamping blocks to move inward along the tension screw. The two clamping blocks lock the guide rail, thereby restricting the movement of the sliding block, and thus restricting the movement of clamping assembly one and clamping assembly two. The drive source is started, and the drive source drives the transmission belt to rotate. The transmission belt drives the driven wheel to rotate, and the pipe is inserted into the "V" groove between the transmission belts of clamping assembly one and clamping assembly two. The rotation of the transmission belts of clamping assembly one and clamping assembly two achieves the traction of the pipe.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
