[0002] Angle steel is a long strip of steel with two sides perpendicular to each other at right angles, also known as angle iron. It is divided into equal-leg angle steel and unequal-leg angle steel. Among them, the two sides of equal-leg angle steel are equal in width. Angle steel has a wide range of uses. As long as it is used in building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, reaction towers and warehouses, in order to obtain angle steel of appropriate length during production and use, it is usually necessary to use a cutting machine, such as an acetylene positioning cutting machine, to cut longer angle steel.

The setting of the translation plate in the utility model facilitates better limiting of the connecting frame, and the setting of the cutting machine body facilitates better cutting of angle steel, flat The arrangement of the first limiting bead and the second limiting bead in the shifting plate facilitates better reduction of the friction between the connecting frame and the rod body. However, the driving mechanism structure for adjusting the position of the cutting machine body in the above-mentioned positioning cutting machine is complex and inconvenient to install and maintain. The above-mentioned positioning cutting machine cannot fix the angle steel during the cutting process of the angle steel, which easily causes the angle steel to shift during the cutting process, affecting the cutting quality. In addition, the position adjustment of the above-mentioned positioning cutting machine is inconvenient, which is not conducive to adjusting the position of the positioning cutting machine according to the storage position of the angle steel, increasing the workload of transporting the angle steel, and is not conducive to saving manpower. Therefore, in order to solve the above-mentioned problems, the utility model proposes an acetylene positioning cutting machine for angle steel processing. Utility Model Content
