Research On Application Of CNC Electro-Hydraulic Bending Machine Tool And Mechanical Compensation

Modern metal sheet metal bending has become an indispensable part of the sheet metal industry processing and gradually occupied an important position in it.In the study of bending machine tool found in the choice of hydraulic compensation system,there are slow response,poor linear compensation variable,high maintenance costs and environmental pollution and other shortcomings.With the development of electric power,electronic technology and motor manufacturing technology,the new hydraulic compensation system which directly drives the bending machine of the machine to replace the bending machine has become a new development direction.The mechanical compensation system provides a set of bending machine tools that are faster than the hydraulic compensation system,with a compensated amount of work that can be linearly compensated and has a very good stability at work.In this design process to learn the basic principles of bending machine tools,while the bending machine tool industry at home and abroad the current market trends in the development of a detailed study in the study found that the hydraulic compensation system in the metal sheet metal bending production In the shortcomings of the lack of summary,we will these shortcomings and difficulties as a mechanical compensation system design program in the key points.First of all,the mechanical compensation system is analyzed and developed on the compensation increment and parameters,and the design scheme is worked out.At the same time,the finite element analysis is used to analyze the frame and the sliders.Through the analysis of the analysis found to replace the hydraulic compensation control system in the stability and compensation of incremental linear changes in the lack of solution.In view of these problems,the mechanical compensation scheme is to drive the motor by compensating the internal compensation ramps by compensating the relative movement of the slanting block to complete the compensation work in the bending process.In the research firm with the strong support of the application of our design,CNC electro-hydraulic bending machine to mechanical compensation system instead of hydraulic compensation system design program so that the machining accuracy has been significantly improved.
