Description

Technical Field

[0001] The utility model relates to the technical field of pipe expansion, in particular to a plastic pipe expansion device. Background Art

[0002] As an important component of chemical building materials, plastic pipe fittings are widely accepted by users for their superior performance, hygiene, environmental protection, and low consumption. Common molding methods for plastic parts include injection molding, blow molding, etc. During the production process and actual use of plastic pipe fittings, the inner diameter of the pipe is different from that of pipe fittings of different standards during the use, so the fittings need to be expanded.

[0003] The publication number in the existing public technology is: CN216829995U. A hole-expanding device for plastic pipe fittings includes a mounting tube, a driving shaft is rotatably connected in the mounting tube, an inner grinding head is fixedly connected to the lower end surface of the driving shaft, a fixed base is fixedly connected to the lower end side wall of the mounting tube, a clamping mechanism for clamping the PE pipe during hole-expanding is provided on the fixed base, a driving mechanism for driving the clamping mechanism is provided on the side wall of the mounting tube, a cross-clamping groove is provided in the driving shaft, a driving rod is provided in the cross-clamping groove, and two symmetrically arranged cross-clamping blocks are fixedly connected to the side wall of the driving rod. The utility model sets a mounting tube, a driving shaft, an inner grinding head and other structures, utilizes the limiting of the driving shaft in the mounting tube during the rotation process, cooperates with the driving shaft to drive the inner grinding head to grind the inside of the pipe fitting, so as to achieve the hole-expanding process and avoid the deformation reset process of hole-expanding in the way of deformation of the inner diameter of the pipe fitting.

[0004] However, the above patent still has certain disadvantages when used: although it can expand the hole of the pipe by means of an internal grinding head, the size of the internal grinding head is relatively single, which results in a relatively limited size of the hole that can be expanded, and it is not possible to perform expansion operations of different sizes well. Subsequently, personnel are required to frequently disassemble, install and replace the internal grinding head, which is time-consuming and labor-intensive, and the use effect is not very good. Moreover, it directly performs extrusion when expanding the hole. Since the texture of the pipe is relatively hard, direct extrusion can easily cause the pipe to rupture, thereby affecting the subsequent hole expansion process and the use of the pipeline, resulting in loss and waste of the pipe.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0030] According to an embodiment of the utility model, a hole expanding device for a plastic pipe is provided.

[0031] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, a reaming device for plastic pipes according to an embodiment of the utility model comprises a workbench 1 and a base 14, an operating frame 7 is arranged at one side of the top of the workbench 1, a fixing plate 18 is installed at the top surface of the operating frame 7 and at the position directly below the workbench, a sliding rod 8 is fixedly installed between the top of one side surface of the fixing plate 18 and the surface of the operating frame 7, a reaming tube 15 is slidably connected to the outer periphery of the sliding rod 8, and the reaming tube 15 is concentrically arranged in multiple groups, and the inner surface of the reaming tube 15 located on the outside is symmetrically provided with a guide slide groove 16, and the reaming tube 15 located on the inside is symmetrically provided with a guide slide groove 16. A guide rod 17 is symmetrically installed at the top position of the surface, and the guide rod 17 is connected to the guide slide groove 16. Positioning holes 9 are symmetrically opened on the surface of the end of the reaming tube 15. A reset spring 13 is symmetrically connected to the surface of the end of the reaming tube 15 between the positioning holes 9, and the other end of the reset spring 13 is connected to the operating frame 7. Between the reset springs 13, a second hydraulic rod 10 is symmetrically installed at the internal top position of the operating frame 7 and the top position of the workbench 1. A mounting box 11 is fixedly installed at one end of the second hydraulic rod 10, and a third hydraulic rod 12 is arranged inside the mounting box 11.

[0032] In one embodiment, a plurality of groups of support plates 2 are symmetrically installed on the other side of the top of the workbench 1, a first hydraulic rod 3 is symmetrically installed on the surface of the support plate 2, one end of the first hydraulic rod 3 is connected to an adjusting clamp ring 4, a processing ring 5 is installed at one end of the support plate 2 near the operating frame 7, and an electric heating ring 6 is installed around the inner part of the processing ring 5. The end position of the pipe to be processed can be heated by the electric heating ring 6 to soften it to a certain extent, so as to facilitate the subsequent smooth hole expansion process.

[0033] In one embodiment, the adjusting clamp ring 4 is composed of a half ring and a spring. The adjusting clamp ring 4 can be used to clamp pipes of different sizes, and the structure of the spring can refer to the structure of the reset spring 13. The specific type can be adjusted according to personnel needs.

[0034] In one embodiment, a base 14 is fixedly installed at the bottom of the workbench 1, and the entire device can be fixed by the base 14 to enhance the overall stability.

[0035] In one embodiment, a slope is provided at the other end of the reaming tube 15. The slope is provided to ensure that the reaming tube 15 can be effectively inserted into the internal position of the reaming tube 15 that needs to be expanded to achieve the expansion operation, thereby avoiding the phenomenon that the reaming tube 15 directly contacts the pipe and cannot be inserted into the pipe.

[0036] In one embodiment, the size of the positioning hole 9 is the same as the size of the end position of the third hydraulic rod 12. The positioning hole 9 is provided to ensure that the third hydraulic rod 12 can be smoothly aligned with it, so as to facilitate the subsequent pushing of the reaming cylinder 15 at the designated position to realize the reaming process of the pipe.

[0037] In one embodiment, a telescopic rod is provided in the empty position in the middle of the reset spring 13. The telescopic rod is provided to support the reset spring 13 to prevent the reset spring 13 from collapsing due to its own weight. At the same time, it can effectively support and fix the unused reaming tube 15.

[0038] In one embodiment, the reaming tube 15 is made of metal material, which ensures the quality of the reaming tube 15 and ensures that it can smoothly expand the tube.

[0039] Working principle: In actual use, personnel can place the pipe that needs to be expanded in the middle position of the support plate 2, and then the relative movement of the first hydraulic rods 3 on both sides can drive the adjusting clamp ring 4 to clamp the pipe. Since the surface of the adjusting clamp ring 4 is provided with a movable half ring and a spring, the compression of the spring can achieve the purpose of clamping pipes of different sizes, thereby expanding the overall use range of the device and facilitating subsequent expansion operations. Then the end position of the pipeline that needs to be expanded can be moved to the inner position of the processing ring 5, and the end of the pipe can be heated to a certain extent by the electric heating ring 6 on the surface of the processing ring 5, so as to facilitate the subsequent expansion process, avoid the hard pipe from being squeezed and damaged, reduce the damage to the pipe, and improve the overall expansion simplicity and expansion quality. Then, when the heating of the pipe is completed, the third hydraulic rod 12 can be moved to the position that needs to be expanded by moving the second hydraulic rod 10 up and down. The surface position of the reaming tube 15 to be used is determined, and then the reaming tube 15 of the corresponding size can be pushed out by the push of the third hydraulic rod 12, so that the pipe can be reamed of the corresponding size. Since the reaming tubes 15 are provided with multiple groups and cover each other, there is no need for manual loading and unloading and replacement during operation, which can effectively reduce the tediousness of operation and expand the operation range of the device, so as to facilitate better use. Since the reaming tubes 15 are connected by guide grooves 16 and guide rods 17, it can be ensured that when reaming tubes 15 of different sizes are used, other reaming tubes 15 will not be affected. At the same time, the unused reaming tubes 15 can be pulled and fixed by the reset spring 13, so as to further reduce the probability of the unused reaming tubes 15 moving, ensure that they can be moved in a targeted manner, and improve the use effect of the device. The device as a whole has the advantages of small reaming damage, various reaming types, and convenient use.
