External thread grooving correction device for threaded pipe machining

Abstract

The invention relates to the technical field of threaded pipes, and discloses an external thread grooving correction device for threaded pipe machining. The external thread grooving correction devicecomprises a shell, the right part of an inner cavity of the shell is rotationally connected with a grooving cutter, the left end of the shell is fixedly connected with a protective cover, and the upper wall and the lower wall of the left part of the shell are both fixedly provided with magnetic tracks. Positioning bases are fixedly connected to the positions, above and below the grooving cutter, on the left wall of the inner cavity of the shell, a correction column is connected to the left portion of each positioning base in a sliding manner, a rotating gear is rotationally connected to the right side of the correction column on the left portion of each positioning base, and an induction block is connected to an inner cavity of each magnetic track in a sliding manner. According to the external thread grooving correction device for threaded pipe machining, corresponding abutting strips are extruded when the grooving cutter deflects, so that the abutting strips drive push rods to push the induction blocks to move, the rotating gears can synchronously drive the correction columns to reset the grooving cutter, and therefore the machining quality of threaded pipes is effectively improved, and the machining cost of enterprises is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of threaded pipes, in particular to an external thread grooving correction device for processing threaded pipes. Background technique [0002] At present, during the processing of the external thread of the threaded pipe, it is necessary to use a fast-rotating grooving knife to cooperate with the movement of the pipe to create the corresponding thread. After long-term contact with pipe fittings, the slotting knife will gradually deviate from the center of rotation due to stress. At this time, due to the lack of corresponding correction devices, quality problems will occur for workpieces that are still grooving, and when the slotting knife deflection problem is serious , because it cannot break the knife in time to stop the grooving process, it will eventually lead to the scrapping of the pipe fittings, resulting in increased processing costs of the enterprise, which is not conducive to the development of the...

[0002] At present, during the processing of the external thread of the threaded pipe, it is necessary to use a fast-rotating grooving knife to cooperate with the movement of the pipe to create the corresponding thread. After long-term contact with pipe fittings, the slotting knife will gradually deviate from the center of rotation due to stress. At this time, due to the lack of corresponding correction devices, quality problems will occur for workpieces that are still grooving, and when the slotting knife deflection problem is serious , because it cannot break the knife in time and stop the grooving process, it will eventually lead to the scrapping of the pipe fittings, resulting in an increase in the processing cost of the enterprise, which is not conducive to the development of the enterprise

[0003] Aiming at the deficiencies of the prior art, the present invention provides an external thread grooving correction device for threaded pipe processing, which has the advantages of effectively improving the processing quality of the threaded pipe, effectively reducing the processing cost of the enterprise, and solving the problem of The external thread grooving device for general threaded pipe processing cannot effectively improve the processing quality of the threaded pipe during use, and the scrapped products of the threaded pipe during processing will increase the cost of the enterprise.
