Portable flame cutting machine for cutting oval shape and application method thereof

Abstract

The invention relates to the field of steel plate cutting and particularly relates to a portable flame cutting machine for cutting an oval shape. The portable flame cutting machine is mainly composed of a flame cutting machine and an oval control mechanism; the oval control mechanism comprises a magnetic base, a cross-shaped sliding groove, a radius adjusting transverse rod and a cutting nozzle height adjusting rod; the cross-shaped sliding groove is fixedly mounted on the magnetic base; sliding blocks are mounted in two vertical and horizontal sliding grooves of the cross-shaped sliding groove; each sliding block is connected with a radius difference adjusting rod through a bearing; the radius adjusting transverse rod is simultaneously connected with two radius difference adjusting rods through fasteners; one end of the radius adjusting transverse rod is connected with the upper end of the cutting nozzle height adjusting rod through a fastener; and the lower end of the cutting nozzle height adjusting rod is also connected with a cutting nozzle of the flame cutting machine through fasteners. The portable flame cutting machine provided by the invention is used for carrying out oval cutting, and the angle of the cutting nozzle can be adjusted, so that a welding groove is formed in a cutting seam; and the groove and cutting are finished at the same time, so that the product quality and the working efficiency are improved.

Description

technical field [0001] The invention relates to the field of steel plate cutting, in particular to a portable flame cutting machine for cutting an ellipse and a usage method thereof. Background technique [0002] With the wide application of steel structures in the industrial and civil construction markets, the types of steel structures manufactured are becoming more and more complex, and the quality and precision requirements are also getting higher and higher. In the manufacturing process, elliptical holes and elliptical parts will be cut. It is necessary for the workers to draw the elliptical cutting trajectory manually, then use the flame torch to cut manually, and then polish the welding groove according to the design requirements. The quality of manual cutting is often not up to the standard. To meet the requirements, the use of grinding wheels to grind the groove requires a lot of labor. Contents of the invention [0003] In view of the above technical problems, th...
