ABSTRACT
Through the introduction of the British company two roll straighter digestion absorption in the Shanghai lida heavy industry manufacture Co., the research analysis, reverse engineering design, successful improvement design. This paper has the comprehensive research on the two roll straighter, analyzed the principle of two roll straightening machine, roller type curve, roller type characteristics, etc. By using nc machine tool measuring point, find out the roller type curve, thus for roller type of surface processing to provide accurate and reliable reference. The qualitative analysis of the roller shape curve, straightening principle, be helpful for further improvement.
To the transmission system and frame structure, working part, analysis and verification of surveying and mapping. The system of motor, deceleration machine, coupling, bearing etc all according to the national standard, realized the full localization. According to the actual situation of improving the design of structure form, make it more simple, practical and reliable, which is beneficial to the maintenance and operation, etc. Two roller to roll body of the straightener, the roller, frame, bearing key parts of the strength, stiffness and life on the mechanical analysis and calculation, according to our country of the standard of design improvement, succeeded in improving two roll straightening machine.
Keywords: two roll straightening machine, CNC machine tool measuring point, design improvement, roller type curve, mechanics analysis
