Hydraulic Servo Position Control System In The Application Of Tube Straightening Machine

Metallurgical equipment straightening machine is an important part of quality control, including pipe straightening machine is one of the major component. With the theory of metal pressure processing, servo control theory and wide application of hydraulic systems, as well as the further improvement in the basic disciplines, making steel products to the performance indicators has improved even more. However, hydraulic servo control system in single pipe straightening machine in the application of the rapid pressure system is still relatively slow development of straightening equipment branch.In-depth analysis of this article Tianjin Pipe Group Co., Ltd. JGL-168series based on the principle of straightening machine, combining the features of our products in accordance with the requirements of the hydraulic servo control system preliminary design, while under the original calculation demonstrates the feasibility of device characteristics. The hydraulic servo control system and related theories of a comprehensive system for the future roll tube straightening machine oblique transformation to provide a theoretical basis. In this paper, the project roll tube straightening machine oblique pressure servo system as the research object, on the oblique roll tube straightening machine working principle, performance characteristics are described. Change the company for the steel product features and quality requirements, according to position feedback for design optimization. In this paper, the development of hydraulic servo system control program, system diagram, the system static and dynamic quality analysis and determine the calibration characteristics. Theoretical advantages and disadvantages of control method. And use MATLAB on the ramp roller pipe straightening machine servo-pressure system simulation, etc. are described.Research, the combination of equipment, work characteristics and product structure, expand the number of trials and feasibility studies. Input-output ratio in the enterprise under the premise of optimal depth analysis of the advantages and disadvantages of hydraulic servo system, combined with characteristics of enterprises to optimize the design of hydraulic servo system to achieve the best return on investment.
