Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing equipment, in particular to a flame cutting machine. Background Technique

[0002] Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, etc., and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between components or parts. When using steel structures, a flame cutting machine is needed to cut and process the steel structures.

[0003] The existing patent CN216462370U discloses a numerically controlled flame cutting machine for steel structure processing, including a column, a moving structure, a fixing structure, a fixing plate, a handwheel, a screw rod, a slider, a sliding plate, a connecting rod, a limiting plate and a flame cutting machine body. The beneficial effect of the utility model is that when the screw rod rotates, it will drive two sliders to slide by threads. Since the thread directions at both ends of the screw rod are opposite, the two sliders will slide relatively. When the two sliders approach each other, the slider will drive the sliding plate and two connecting rods thereon to approach each other, and then the two groups of connecting rods will clamp and fix the steel plate on the fixing plate, which greatly facilitates the fixing work of the steel plate. Subsequently, the power supply of the flame cutting machine body is connected, the flame cutting machine body is started, and the moving structure is used to drive the flame cutting machine body to move, so that the flame cutting machine body quickly cuts the steel plate. At the same time, when the steel plate is cut, the two sections of the steel plate are still clamped and fixed by two limiting plates respectively, which greatly improves the stability of the steel plate cutting.
