120MN Hydraulic Press Technological Transformation Study

The 120MN free forging hydraulic press that imported from Czech is large-scale and key equipment of a enterprise. Being restriction of design means and manufacturing capacity at that time, this apparatus have had some fault, for example, outmoded structure, high rate of failure the shorter cycle of maintenance, low productivity, and it cause serious influence on production. For this reason, must carry on technological transformation to the hydraulic press, to lengthen the service life of the parts, improve apparatus precision, efficiency and dependability.This subject has studied the design characteristic of the noumenon structure of the hydraulic press and transform scheme, employ the law of finite element, carry on analysis of intensity and rigidity to the activity crossbeam structure. Combine repairing process of the main noumenonn parts with technological transformation. According to the development trend of the forging hydraulic press, main research results and characteristic are as follows:1. Have study the structure, principle and characteristic of the hydraulic press, has analyzed the subject problem that the hydraulic press exists, have propose the technological transformation main method of the hydraulic press, has summarized domestic and international relevant research results; 2. Take the research emphasis on the application of the general optimizes design method in new activity crossbeam, optimize the structural parameter of the activity crossbeam, guarantee the design plan reaches the best; 3. Have set up the finite element mechanics model of the activity crossbeam, has carry on the finite element analyze of three-dimensional to this structure's intensity, received some important results such as the stress distributed state of this component, etc.; 4.Have studied the repair craft scheme of the hydraulic press, has put forward the correct dismantlement of the hydraulic press and installation process rules of the large-scale.The technological transformation of this hydraulic press is with strong points, modern techniques, and it is short, with low costs, profitable. This subject has offered the reference on technology in designing the new hydraulic press and...
