Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
Example (b): it is known from the background art that the threaded connection of PVC pipes is an important connection method when connecting metal fittings, and in the case of non-standard PVC pipes, it is necessary to thread a thread at one end of the PVC pipe. Unlike the tapping process in machining, the tapping of PVC pipe is not done by cutting the material, but by extruding the PVC pipe with a threaded "tap" to produce the corresponding threads.
Referring to fig. 1-3, a pipeline tapping device comprises a central tube 1, a central rod 2 which can rotate in the central tube 1 is arranged in the central tube 1, a tapping head 3 is arranged at one end of the central rod 2, threads for tapping are arranged on the tapping head 3, a guide cylinder 4 which extends into the tapping head 3 is arranged at the front end of the tapping head 3, the front end of the guide cylinder 4 is conical, and a hand wheel 5 is arranged at the other end of the central rod 2; the central tube 1 is provided with a supporting rod 6 which is perpendicular to the central tube 1, and the supporting rod 6 is connected with a base 7 for supporting the device. The outer diameter of the guide cylinder 4 is smaller than the small diameter of the thread of the tapping head 3, the outer diameter of the guide cylinder 4 is equal to or smaller than the inner diameter of the pipeline, and specifically, the difference between the inner diameter of the pipeline and the outer diameter of the guide cylinder 4 is 0-2 mm.
When the PVC pipeline needs the tapping, the one end heating of PVC pipeline is the softened state earlier, later with tapping head 3 stretch into in the one end that the PVC pipeline was heated, rotate tapping head 3 through hand wheel 5, tapping head 3 is at the pipeline internal rotation, the screw thread on the tapping head 3 is the tapping of pipeline inner arm extrusion cutting thread realization to the PVC pipeline, when the tapping, guide cylinder 4 stretches into in the pipeline, guide cylinder 4 plays the guide effect to the motion of tapping head 3 in the pipeline, consequently, tapping head 3 can remove and be difficult crooked along the axial direction of pipeline when tapping, the internal thread quality that becomes at the tapping pipe inner wall tapping is higher, thereby improve the pipeline and metal joint's the quality of being connected. Moreover, the external diameter of guide cylinder 4 is less than the screw thread path of tapping head 3 and can make things convenient for guide cylinder 4 to stretch into the pipeline smoothly, and secondly, the external diameter of guide cylinder 4 is less than the screw thread path of tapping head 3, and after the tapping finishes, when taking out guide cylinder 4 together with tapping head 3 from the pipeline, the internal thread that the tapping has been good is not fragile to guide cylinder 4, when guaranteeing that guide cylinder 4 can stretch into the pipeline smoothly, also makes guide cylinder 4 can not rock by a wide margin in the pipeline.
Be equipped with a plurality of guide ways 41 that extend along the 4 axial directions of guide way on the outer circumference of guide way 4, a plurality of guide ways 41 evenly distributed sets up guide ways 41 on the circumference of guide way 4 for when the external diameter difference of pipeline internal diameter and guide way 4 is very little, guide way 4 is difficult for the card to die in the pipeline, makes things convenient for the removal of guide way 4 in the PVC pipeline.
In order to reduce the mass of the tapping head 3 and the guide cylinder 4, the tapping head 3 and the guide cylinder 4 are hollow. The tapping head 3 can be made of a metal material and the guide cylinder 4 can be made of a plastic material. For PVC pipelines with large diameters, the diameters of the tapping head 3 and the guide cylinder 4 are necessarily large, the tapping head 3 and the guide cylinder 4 are hollow, the using function is not influenced, meanwhile, a large part of mass can be reduced, and the operation is convenient.
The base 7 is provided with a plurality of connecting holes 71, so that the base 7 can be fixed on the ground, a table or a vehicle by using bolts conveniently, and the use is convenient. When using this pipeline chasing bar, stable base 7 can effectively improve work efficiency, according to actual conditions, can use the bolt to fix base 7 on different equipment for the use.
It should be noted that the embodiment of the present invention provides a pipe tapping apparatus, which not only can tap PVC pipes, but also can be used for tapping other plastic pipes.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
