Research For New Internal Expansion Type Clamping Mechanism Floating Cutting Groove Machine

Long distance oil and gas pipeline construction by the topography of the land and municipal,land acquisition and other conditions, the use of substantial increase in the amount of bending.But more than8degrees elbow needs in camber production workshop by medium frequencyheating equipment of hot bending molding, pipe chamfering machine is an important procedurein the pipe production. China’s oil and gas pipeline construction of large-scale development, aswell as a large caliber, high grade pipeline steel pipe and pipe applied to processing equipmenthas brought the huge challenge.Large diameter heat bend pipe beveling machine is oil and natural gas transmission pipeprocessing equipment, through the clamping mechanism for technical analysis, put forwardinside expanding type clamping means, can achieve small size using the pipe diameter aspositioning datum, realizes the pipe clamping positioning, and to ensure that coaxially with thespindle, ensure pipe groove processing quality.The article with "big-diameter hot-bending bend groove machine" project as thebackground, through the research of this topic, the research and development of large diameterhot bending pipe beveling machine internal expanding type clamping mechanism key technologyresearch and analysis, using the3D Solid works design element on the mechanical structuredesign is optimized, and the use of simulation software, the kinematics simulation.This paper is the combination of production and scientific research, the use of theory andpractice, to analyze and study the problems, directly combined with production practice, providea theoretical basis for further optimization of the product. In this paper, by usingthree-dimensional design, dynamic analysis and field test of pipe beveling machine internalexpansion clamping mechanism and determined the optimal scheme, and puts forward a newmethod for processing hot-bending bends.
