Novel hard alloy pipe fitting

Abstract

The invention discloses a novel hard alloy pipe fitting which comprises a bottom frame. A column rod is fixedly arranged on the top end face of the bottom frame. An installation frame is fixedly arranged on the top end face of the column rod. A machining frame is arranged at the left side end of the installation frame. First penetrating ports are bilaterally symmetrically formed in the bottom endface of the machining frame. Adjustment and control cavities extending up and down are formed in the inner top walls of the first penetrating holes. Conic frames are installed on the bottom walls of the adjustment and control cavities in a running fit mode. Toothed rings are fixedly arranged on the peripheries of the conic frames. Second penetrating ports opposite to the first penetrating ports are formed in the conic frames in an up-down run-through mode. Adjustment and control frames are installed in the adjustment and control cavities in a sliding fit mode. Conic wheels used for being engaged with the conic frames are installed at the bottom ends of the adjustment and control frames in a running fit mode. Drill bits are fixedly installed on the bottom end faces of the conic wheels and extend into the second penetrating ports and the first penetrating ports. A through hole is formed between the bottom ends of the adjustment and control cavities in the left side and the right side ina communicating mode.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing, in particular to a novel cemented carbide pipe fitting. Background technique [0002] During the production and processing of cemented carbide pipe fittings, the punching of cemented carbide pipe fittings in the prior art mainly relies on manual adjustment and replacement of the drill bit, and the use efficiency is low. When the drill bit needs to be replaced repeatedly, it needs to be disassembled repeatedly, which greatly affects the cemented carbide pipe fittings. The preparation quality and preparation speed, and the traditional drilling equipment is not convenient to adjust the rotation direction of the drill bit. Therefore, the drilling limitations are strong, the use is inconvenient, and the production and processing efficiency of the cemented carbide pipe fittings is affected, which needs to be improved.
