Semi-automatic short distance cutting machine and its cutting method

Abstract

The invention provides a semi-automatic short-range cutting machine and a cutting method thereof and relates to a small-sized machine used for cutting a profile steel docking groove. The semi-automatic short-range cutting machine comprises a cutting torch (8), on which a manual micromatic setting device (6) is arranged; the manual micromatic setting device (6) is installed on a machine base (3); the machine base (3) is installed on a rail (1-5) in an adjustable quadrilateral mechanism (1) through a rail slider (2); an angle adjustment device (7) is installed at the bottom of the manual micromatic setting device (6); the machine base (3) is provided with a permanent magnet direct current deceleration motor (5); a gear rack (4) is used for realizing the transmission between the permanent magnet direct current deceleration motor (5) and the rail (1-5) so as to drive the cutting torch (8) to run to finish cutting task; a strong-force magnetic base (1-1) consists of two adjacent rotary fixing points and two rotary or clamped fixing points in the adjustable quadrilateral mechanism (1) so that the whole machine is firmly fixed on a processed workpiece. The invention fills the blank in the prior art; the semi-automatic short-range cutting machine has advantages of simple structure, portability and capability of site operation; and the provided cutting method can effectively guarantee cutting quality.

Description

technical field [0001] A semi-automatic short-distance cutting machine and a cutting method thereof are small-scale equipment used for cutting butt joint grooves of steel structure sections. Background technique [0002] The cutting of actual section steel, especially the cutting of H-section steel grooves, mostly requires on-site welding butt joint groove workshops. Since the relevant national standards require that the grooves should be uniform, smooth, and free of uneven defects, the previous production methods There are many problems. For example, using manual gas cutting with line drawing or using a semi-automatic gas cutting car to open the bevel. Manual gas cutting requires a high level of operation for workers. Due to the large size of the gas cutting car, it is inconvenient to operate. Also there is no small-sized automatic cutting machine that can have portable equipment, and facilitate on-site operation, and can guarantee the quality of processing. In addition, d...

[0002] The cutting of actual section steel, especially the cutting of H-section steel grooves, mostly requires on-site welding butt joint groove workshops. Since the relevant national standards require that the grooves should be uniform, smooth, and free of uneven defects, the previous production methods There are many problems. For example, using manual gas cutting with line drawing or using a semi-automatic gas cutting car to open the bevel. Manual gas cutting requires a high level of operation for workers. Due to the large size of the gas cutting car, it is inconvenient to operate. Also there is no small automatic cutting machine that can have portable equipment, and facilitate on-site operation, and can guarantee the quality of processing

In addition, due to the narrow space in the web of the H-beam and the short groove length, the processing requirements are high, and the technical requirements for the designers in the industry are also higher.

Therefore, no ideal small-scale machine technology for cutting steel structural section steel grooves has been found so far no matter whether it is a patented invention or in the domestic and foreign markets.
