Description

Technical Field

[0001] The utility model relates to the technical field of pipe flaring, in particular to a tetrafluoroethylene pipe flaring and flanging device. Background Technique

[0002] Tetrafluoroethylene pipes, also known as polytetrafluoroethylene pipes, are pipes made of polytetrafluoroethylene (PTFE) material. PTFE is a polymer material with excellent corrosion resistance, high temperature resistance, wear resistance and low friction coefficient. Therefore, tetrafluoroethylene pipes are widely used in the fields of chemical industry, petroleum, pharmacy, electronics, machinery, etc. When processing tetrafluoroethylene pipes, a flaring and flanging device is required.

[0003] For example, a Chinese patent (Publication No.: CN218535621 U) discloses a pipe flaring and flanging device, including a base. A placement rack for placing tetrafluoroethylene pipes is arranged on the base. An expansion part for flaring the tetrafluoroethylene pipes is also arranged on the base. A driving part for driving the expansion part to move along one side of the placement rack is arranged on the base. An auxiliary extrusion assembly is arranged on one side of the expansion part. By setting the expansion part, the driving part and the auxiliary extrusion assembly, the pipe edge of the tetrafluoroethylene pipe can be flared for the second time, thereby improving the flaring effect.

[0004] The above technical solution also has the following defects. Although in this pipe flaring and flanging device, by setting the expansion part, the driving part and the auxiliary extrusion assembly, the pipe edge of the tetrafluoroethylene pipe can be flared for the second time, thereby improving the flaring effect. However, in actual use, the sliding frame slides more smoothly in the T-shaped groove to drive the extrusion plate to move stably. However, when the sliding frame is moving, it is easily affected by force, and it may slide out from the right side of the T-shaped groove on the base, resulting in the sliding frame falling and being damaged. Based on this, a tetrafluoroethylene pipe flaring and flanging device is proposed to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a tetrafluoroethylene pipe flaring and flanging device, which has the advantages of improving the stability of the device, etc., and solves the problem that in actual use of the existing tetrafluoroethylene pipe flaring and flanging device, the sliding frame is easy to slide out from the right side of the T-shaped groove on the base, resulting in the sliding frame falling and being damaged.

[0006] To achieve the above object, the utility model provides the following technical solution: A tetrafluoroethylene pipe flaring and flanging device, including a base, an expansion assembly and a clamping assembly are arranged on the base. A chute is opened on the upper surface of the base. A slider is slidably connected to the inner wall of the chute. A support rod is fixed to the top of the slider. A driving motor is fixed to the right side of the support rod. An extrusion plate is fixed to the output shaft of the driving motor. A stabilizing mechanism is arranged on the support rod and the base;

[0007] The stabilizing mechanism includes a connecting plate fixed to the outer surface of the support rod, a starting component, and a fixing component;

[0008] The starting component includes an adjusting rotating rod whose one end is rotatably connected to the front surface of the support rod through a bearing and the other end penetrates outside the connecting plate. A handle is fixed to the front surface of the adjusting rotating rod. A first bevel gear is fixed to the outer surface of the adjusting rotating rod. Second bevel gears are meshed on both the left and right sides of the outer surface of the first bevel gear. A worm whose one end is rotatably connected to the inner side wall of the connecting plate through a bearing is fixed to the inner wall of the axis of the second bevel gear. A worm gear is meshed on the outer surface of the worm. A bidirectional screw rod that is rotatably connected between the front and rear sides of the inner cavity of the connecting plate through a bearing is fixed to the inner wall of the axis of the worm gear. Moving blocks are threadedly connected to both the front and rear sides of the outer surface of the bidirectional screw rod.

[0009] Furthermore, thread strips are fixed to the outer surfaces of the left and right worms, and the spiral directions of the two thread strips are opposite.

[0010] Furthermore, two support seats are fixed to the inner front side wall of the connecting plate, and the support seats are rotatably connected to the worms.

[0011] Furthermore, a rotating hole that is rotatably connected to the adjusting rotating rod is formed in the front surface of the connecting plate.

[0012] Furthermore, the left and right bidirectional screw rods are symmetric about the center line of the support rod.

[0013] Furthermore, the fixing component includes a limiting block fixed to the lower surface of the moving block and penetrating outside the connecting plate. The fixing component further includes two guiding plates fixed to the upper surface of the base. Guiding grooves are formed on the opposite sides of the two guiding plates.

[0014] Furthermore, the guiding grooves are slidably connected to the limiting blocks, and the cross section of the limiting blocks is L-shaped.

[0015] Furthermore, two moving holes are formed in the lower surface of the connecting plate, and the moving holes are slidably connected to the limiting blocks.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] After the first flaring of the PTFE pipe flaring and flanging device through the clamping component and the flaring component, the slider is placed in the chute, the adjusting rotating rod is rotated, so that the two moving blocks drive the limiting block to move into the guiding groove. Then, the driving motor drives the pressing plate to rotate to the right side of the PTFE pipe, and the flaring component presses the pressing plate again to perform secondary flaring on the pipe edge of the PTFE pipe, improving the flaring effect. During the process of the flaring component driving the pressing plate to move and press, the support rod will be driven to move. At this time, the limiting block moves along the guiding groove, enabling the support rod to move stably and preventing it from sliding out from the right side of the base under the influence of external forces, resulting in the dropping and damage of the component and affecting the working efficiency of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 and Figure 3 , a PTFE pipe flaring and flanging device in this embodiment includes a base 1, a flaring component 2 and a clamping component 3 are arranged on the base 1, a chute 4 is opened on the upper surface of the base 1, a slider 5 is slidably connected to the inner wall of the chute 4, a support rod 6 is fixed to the top of the slider 5, a driving motor 8 is fixed to the right side of the support rod 6, a pressing plate 9 is fixed to the output shaft of the driving motor 8, and a stabilizing mechanism 7 is arranged on the support rod 6 and the base 1.

[0025] It should be noted that the stabilizing mechanism 7 ensures that the device can move stably when performing secondary extrusion on the PTFE pipeline, avoiding slipping out from the right side of the base 1 under the influence of external forces, further protecting the device and improving the stability of the device during operation.

[0026] Please refer to Figures 1 to 4 , in order to make the device more stable when performing flaring operation on the PTFE pipeline, the stabilizing mechanism 7 in this embodiment includes a connecting plate 712 fixed on the outer surface of the support rod 6, a starting component and a fixing component. The starting component includes an adjusting rotating rod 701 whose one end is rotatably connected to the front surface of the support rod 6 through a bearing and one end penetrates to the outside of the connecting plate 712. A handle 702 is fixed on the front surface of the adjusting rotating rod 701. A first bevel gear 703 is fixed on the outer surface of the adjusting rotating rod 701. Both the left and right sides of the outer surface of the first bevel gear 703 are engaged with a second bevel gear 704. A worm 705 whose one end is rotatably connected to the inner side wall of the connecting plate 712 through a bearing is fixed on the inner wall of the axis center of the second bevel gear 704. Threaded bars are fixed on the outer surfaces of the left and right worms 705, and the spiral directions of the two threaded bars are opposite. A worm gear 706 is engaged with the outer surface of the worm 705. A bidirectional screw 707 whose one end is rotatably connected between the front and rear sides of the inner cavity of the connecting plate 712 through a bearing is fixed on the inner wall of the axis center of the worm gear 706. Moving blocks 708 are threadedly connected to both the front and rear sides of the outer surface of the bidirectional screw 707. By rotating the handle 702, the adjusting rotating rod 701 and the first bevel gear 703 are driven to rotate. The first bevel gear 703 is engaged with the second bevel gear 704, so that the second bevel gear 704 drives the worm 705 to rotate. The worm 705 is engaged with the worm gear 706, and the worm gear 706 drives the bidirectional screw 707 to rotate, so that the two moving blocks 708 move in opposite directions at the same time, providing power for the subsequent adjustment of the position of the fixing component.

[0027] Among them, two support seats are fixed on the inner front side wall of the connecting plate 712. The support seats are rotatably connected to the worm 705, and the support seats provide support and rotational connection for the worm 705. A rotating hole rotatably connected to the adjusting rotating rod 701 is formed on the front surface of the connecting plate 712. The left and right bidirectional screws 707 are symmetric about the center line of the support rod 6, ensuring the synchronous movement of the moving blocks 708 and improving the work efficiency and accuracy.

[0028] Meanwhile, the fixing component includes a limiting block 709 fixed to the lower surface of the moving block 708 and penetrating to the outside of the connecting plate 712. The fixing component further includes two guiding plates 710 fixed to the upper surface of the base 1. Guiding grooves 711 are formed on the opposite sides of the two guiding plates 710. The guiding grooves 711 are slidably connected to the limiting block 709. The cross-section of the limiting block 709 is L-shaped. Two moving holes are formed on the lower surface of the connecting plate 712. The moving holes are slidably connected to the limiting block 709. The moving block 708 drives the limiting block 709 to slide along the guiding grooves 711 of the guiding plates 710, which is convenient to ensure that the device can move stably when performing secondary extrusion on the tetrafluoroethylene pipe, and avoid sliding out from the right side of the base 1 under the influence of external force, resulting in the dropping and damage of the components and affecting the working efficiency of the device.

[0029] The working principle of the above embodiment is as follows:

[0030] First, the clamping component 3 is used to clamp the tetrafluoroethylene pipe, and the flaring component 2 is used to perform flaring operation on the tetrafluoroethylene pipe. Then, the slider 5 can be placed inside the chute 4 formed on the base 1, which can provide a certain sliding track for the slider 5. Then, the adjusting rod 701 is rotated by the handle 702, driving the first bevel gear 703 to rotate. The first bevel gear 703 meshes with the second bevel gears 704 on the left and right sides, causing the second bevel gears 704 to rotate, and then driving the worm 705 to rotate. The worm 705 meshes with the worm gear 706, and the worm gear 706 drives the bidirectional screw 707 to rotate. Due to the special design of the bidirectional screw 707, the two moving blocks 708 will move in opposite directions at the same time. A limiting block 709 is fixed to the lower surface of the moving block 708. The limiting block 709 penetrates the connecting plate 712 and is slidably connected to the guiding grooves 711 on the guiding plates 710. Therefore, when the moving block 708 moves, it will drive the limiting block 709 to move into the guiding grooves 711. Then, the driving motor 8 drives the pressing plate 9 to rotate, and the pressing plate 9 can rotate to the exact right side of the tetrafluoroethylene pipe. Then, the flaring component 2 can extrude the pressing plate 9 again, so that the pressing plate 9 performs secondary flanging on the pipe edge of the tetrafluoroethylene pipe, thereby improving the flanging effect. During the process of the flaring component 2 driving the pressing plate 9 to move and extrude, it will drive the support rod 6 to move. At this time, the limiting block 709 moves along the guiding grooves 711, enabling the support rod 6 to move stably, so that the support rod 6 is not easily affected by external force when moving, resulting in its own sliding out from the right side of the base 1, causing the components to drop and be damaged, and affecting the working efficiency of the device.
