Diameter-adjustable pipe fitting cutting device and cutting method thereof

Abstract

The invention discloses a diameter-adjustable pipe fitting cutting device and belongs to the technical field of pipe fitting cutting. The diameter-adjustable pipe fitting cutting device comprises a baseplate, wherein a clamp support plate is arranged on the left side of the top of the baseplate; a dovetail guide is arranged on the outer wall of the right end of the clamp support plate; a round table lug is arranged on the outer wall of the right end of the clamp support plate and located at the front end of the dovetail guide; a fixed link is arranged at the right end of the round table lug; external threads are formed at the right end of the outer wall of the fixed link; an eccentric round disk sleeves the outer wall of the fixed link; a movable V-shaped block is arranged at the right endof the clamp support plate; and a fastening screw is arranged at the tops of a movable turnover clamp plate and a fixed clamp plate through through holes. The cutting device suitable for pipe fittings with different diameters finishes fixation of the pipe fittings with different diameters through the V-shaped block and a clamp plate component and finishes cutting of the pipe fittings with different diameters through a combined cutting component, so that the university of the pipe fitting cutting device is improved.

Description

technical field [0001] The invention relates to the technical field of pipe cutting, in particular to a diameter-adjustable pipe cutting device and a cutting method thereof. Background technique [0002] For pipe fittings with larger diameters, it is generally used in a ring with a larger diameter, and the cutting device is installed on the ring so that it can move circumferentially. The pipe fittings penetrate from the center of the ring and adjust along the radial direction of the ring. The telescopic position of the cutting knife is used to achieve cutting. Due to the large diameter difference between different pipe fittings, when clamping the pipe fittings, it is necessary to use different clamps, and only clamp the two ends of the pipe fittings. When cutting, the pipe fittings have a large bending moment. It is easy to jam the gear, and the incision will be jagged, the quality is poor, and it needs a manual hand-held cutting machine to cut, which is unstable, poor in sa...
