Abstract

The invention discloses a rotary cutter head for a pipe cutting machine. The cutter head comprises a cutter head body with a center hole, a cutter feeding mechanism is arranged on the cutter head body, the cutter feeding mechanism comprises a slider-crank mechanism, the slider-crank mechanism comprises a shifting block, a mandrel and a sliding block, and a radial sliding groove in radial sliding fit with the sliding block is formed in the cutter head body. A rotary cutting cutter assembly is fixed to the sliding block, a cavity used for containing the shifting block is formed in the cutter head body, the shifting block is of a V-shaped structure, the two side ends of the shifting block are a main touch arm and a rotating arm respectively, the mandrel penetrates through the rotation centerof the shifting block and is hinged to the cavity, and a shifting working face is formed at the top of the rotating arm. A shifting groove in contact fit with the shifting working face is formed in the sliding block, and the broach mechanism of the pipe cutting machine drives the main touch arm to move and drives the rotating arm to rotate around the rotation center. The cutter head is compact instructure, stable in operation, high in automatic pipe cutting efficiency, adjustable in pipe cutting diameter and accurate in cutting size.

Description

technical field [0001] The present application relates to the technical field of pipe cutting machines, in particular to a rotary cutter head for pipe cutting machines. Background technique [0002] Steel pipe is a hollow profile, the most common cross-sectional shape is circular, and it is widely used in fluid transmission and structure composition. When steel pipes are used to manufacture mechanical parts, they are first cut to length by a cutting process. The equipment commonly used in the cutting process is a pipe cutting machine. Most of the pipe cutting machines currently on the market are lathe-type pipe cutting machines, that is, the steel pipe is rotated, the cutter is fixed, and the processing method is fed radially along the steel pipe. Since the steel pipe usually has a length of 6-12m, the noise after the overall rotation is large, the energy consumption is high, the feeding positioning method is backward, and the fixed length of the workpiece is not accurate, ...
