Portable circle cutting machine suitable for circular thick plate cutting and cutting method thereof

Abstract

The invention provides a portable circle cutting machine suitable for circular thick plate cutting and a cutting method of the portable circle cutting machine. The portable circle cutting machine comprises a cutting machine and a triangular-pyramid-shaped frame. Supporting legs which are used for fixing the frame to a steel plate to be cut are arranged on the three vertexes of the bottom surface of the frame. A stand column which is used for aligning to the circle center of the steel plate to be cut is fixedly arranged below the vertex of the frame. A rotating platform where the cutting machine is placed is arranged on the lower portion of the stand column, a guide rod is transversely arranged on the outer side of the rotating platform, and a guide wheel is arranged at the lower end of the outer side of the guide rod. The portable circle cutting machine can process workpieces with the specifications beyond the working range of the circle cutting machine, can also omit the purchase expense of a circle cutting machine, saves the cost, is high in efficiency, smooth in notch and attractive, has the effect close to the effect of plasma cutting of a machine tool, can be arranged on the horizontal plane or the inclined plane in an attracted mode to conduct 0-45-degree groove cutting, and can be widely applied to petroleum, chemical engineering, shipbuilding and machining enterprises.

Description

technical field [0001] The invention relates to cutting equipment, in particular to a portable circular cutting machine suitable for cutting circular thick plates and a cutting method thereof. Background technique [0002] Steel plate circular cutting usually adopts wire cutting, laser cutting and other methods. The existing methods have some disadvantages: one is to purchase a CNC cutting machine tool, which can process large-size steel plates on a gantry-type CNC plasma cutting machine, but requires the cooperation of a crane and a forklift, which is costly and cannot be realized in a prefabricated structure. The upper part is cut; one is to use manual acetylene gas cutting after scribing, but it is difficult to ensure smooth cutting surface when cutting circles manually, and it is not a small expense to repurchase a special circle cutting machine; in summary, the development of a It is of great significance to develop a portable circular cutting machine that can meet the...
