Dual-purpose threading tool for petroleum pipeline

Abstract

The invention discloses a dual-purpose threading tool for a petroleum pipeline and belongs to the field of machining. The key point of the technical scheme is as follows: the dual-purpose threading tool for the petroleum pipeline comprises a threaded cutter bar, a tool bit and a chip removal device, wherein the tool bit is fixedly connected to the bottom of the threaded cutter bar; the side, closeto the tool bit, of the threaded cutter bar is fixedly connected to the chip removal device; the outer wall of the chip removal device is movably connected to a telescopic rod; the outer wall of thetelescopic rod is movably connected to a split movable rod; a thread is welded to the inner wall of the telescopic rod; the upper wall of the thread is movably connected to the bottom end of the splitmovable rod; and the side, far from the tool bit, of the telescopic rod is fixedly connected to a first chip guide spoon. As the chip removal device is arranged on the outer wall of the threading tool, two chip guide spoons are arranged on the chip removal device and the chip removal device can stretch, so that a flexible effect of the chip removal device is achieved, and the dual purposes are achieved; by arranging a high speed steel cutting edge, the machining efficiency of a threaded hole can be improved; and a chromium carbide wear-resistant layer is arranged, so that wear of the tool bitcan be reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a dual-purpose oil pipe threading tool. Background technique [0002] The dual-purpose oil pipe threading tool is a tool used to process threaded holes on the inner wall of the oil pipe. It includes a threaded cutter rod and a cutter head. The cutter head is connected to the end of the threaded cutter rod, and the cutter head can be aligned with the oil Pipe, so as to achieve the purpose of processing threaded holes, but in use, the thread tool only has the function of processing threaded holes, so that the utilization of the tool is not sufficient, and the tool is prone to wear and tear during work, and the processing speed is slow. [0003] The Chinese patent with authorized notification number CN207372458U discloses a kind of internal thread tool with guiding positioning, which is provided with rollers and anti-shake sliders. By using the anti-shake sliders with rollers as...

[0002] The dual-purpose oil pipe threading tool is a tool used to process threaded holes on the inner wall of the oil pipe. It includes a threaded cutter rod and a cutter head. The cutter head is connected to the end of the threaded cutter rod, and the cutter head can be aligned with the oil Pipe, so as to achieve the purpose of processing threaded holes, but in use, the thread tool only has the function of processing threaded holes, so that the use of the tool is not sufficient, and the tool is prone to wear and tear during work, and the processing speed is slow

[0003] The Chinese patent with authorized notification number CN207372458U discloses a kind of internal thread tool with guiding positioning, which is provided with rollers and anti-shake sliders. By using the anti-shake sliders with rollers as support during processing, the support effect is good and effective. It solves the vibration of the tool rod, improves the surface roughness and precision of the thread, and greatly improves the processing efficiency. However, in actual use, the thread tool cannot achieve dual-purpose effects. When processing threaded holes, a large number of chips will be generated. , and the low flexibility of the chip removal device often leads to incomplete chip removal. At the same time, the thread cutter is not sharp enough and prone to wear, which affects the service life of the cutter head
