Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cutting devices, and in particular relates to a semi-automatic cutting device for the arc surface of a tabletting elbow. Background Art
[0002] Flame cutting uses a gas flame (a flame formed by oxygen and fuel gas) to heat the surface of the steel plate to reach the combustion temperature locally, and then introduces a high-purity, high-speed cutting oxygen flow to cause the metal to undergo a violent combustion reaction and release heat. At the same time, the huge kinetic energy of the high-speed cutting oxygen flow is used to blow away the combustion products and form a slit, forming an incision on the material. When using flame cutting devices to cut arc surfaces and spherical workpieces, most factories currently use manual cutting of arc surfaces, which is inefficient and has irregular cutting seams. Since the handheld cutting gun is prone to shaking, the incision on the surface of the workpiece deviates from the specified trajectory, greatly reducing the cutting accuracy and affecting the welding quality. If a large-scale fully automatic elbow cutting machine is purchased, the price is expensive and generally small enterprises cannot afford it. Therefore, it is necessary to design a low-cost, easy-to-operate, and efficient arc surface cutting device. Utility Model Content
