The Study On The Mechatronics Technology Of The Metallographic Sample Mounting Press

According to the mechatronics principle, the paper analyzed and designed the whole modelling, mechanical structure and control system of the mounting press. It realized the automatic control through the machine-electricity reasonable combing, software and hardware cooperating, which formed a piece of internal matching rationally and external efficiency.The main structure of the mounting press utilized CAD technology to draw automatically and optimize parameter. As for the executive system was concerned, its function was achieved with step motor, which was used to control speed and the position of the down mold. The executive system included worm gear, guide screw nut and step motor. The machine adopted omni bearing cooling system and heater with good performance. So the sampling time was shorted and the energy was saved. The cover was designed and it could be darwn forth and back by a low-speed motor, which improved the automatic degree.Single -chip microprocessor, which meanwhile realized the low cost and high automation, was adopted for controlling system. It used Fuzzy Algorithm to control the pressure and temperature of the powder. Fuzzy Algorithm was realized easily, and the system could abtain good control result. It realized the measuring of the temperature, pressure and position by using various of sensor technology.The mounting press with novel designing fashion and rational structure could operate without supervision. It improved working efficiency as well as had higher use value and wide application prospect.
