Abstract
In today's economy growing, the pipe has been applied to by more and more fields, including the Marine economy, petroleum chemical industry production and construction, urbanization construction of natural gas transportation, has e another necessity of economic development. This design is to analyze the present situation of bend groove device at home and abroad, the advantages and disadvantages of when the cutting groove, conceived a processing quality and production capacity can meet the market demand of a bend the bevel gear design. This paper analyzes the theory of the device, the overall structure, the working principle and the choice of the key motor, the calculation of the machine tool and the calculation design of the clamping device. Mainly includes the general layout design of the machine tool, the selection calculation, the calculation of cutting force of the motor, V belt transmission design and calculation, the calculation of bearing selection, the design and calculation of the wheel, the design calculation of clamping device, the design calculation of feeding device, etc. It also includes the design of the floating tool holder, which can ensure that the irregular shape of the workpiece and the defective pipe fittings can be processed according to the process , the machining equipment of elbow groove is designed.
Keywords: Elbow; elbow beveling device; the status quo at home and abroad
