Design And Dynamic Analysis Of Automatic Freezing Plate Molding Machine

With the developing of industrial automation, the demand of auto-manufacture in factory is highly increasing. The operating system with purely mechanical work is inefficient, which can not satisfy the production requirements of modern society. At present, the strength state enterprises have their own R&D center. They have the ability to do new products developing, processing technology research and processing design. But the technological forces of many private enterprises and small state enterprises are weak. They are still difficult to solve their technical problems.A new type of automatic freezing plate molding machine is designed in this thesis, in order to improve the production efficiency. The process of freezing plate molding belongs to sheet metal forming. Sheet metal forming, as one of the craftwork methods in stamping formation, is widely used in practical production.The automatic freezing plate molding machine can make the flat aluminous sheet metal into the freezing plate automatically. The PLC is used to control the hydraulic system, and the hydraulic system is to control the operating system. The PLC has the advantages of easy to compiler program; convenient to modification, etc. the hydraulic control system has the advantages of move smooth, longevity, high-level efficiency, etc. The automatic freezing plate molding machine has the advantages of saving manpower and improving efficiency. It fully embodies the advantages of MECHATRONICS.The main contents of the thesis are summarized as follows:1. After studying the overview of material forming technology, and the production technology of freezing plate, the automatic freezing plate molding machine is designed. The sizes of the main components in the automatic freezing plate molding machine are determined by analyzing the forces acting on the components.2. According to the needs of working procedure, the most logical hydraulic control system is designed.3. A PLC control system is designed to control the hydraulic system. 4. Do the simulation of the dynamic pressure and the dynamic speed of the hydraulic cylinders when the hydraulic cylinders extend by using Power Bond Graph and MATLAB.
