This paper introduces the design process of the press, from determining the transmission scheme, to determining the size parameters and motion analysis of the pressure and main mechanism, to selecting the motor, and finally designs and calculates the main components of the press transmission system.
This time, through the movement analysis and comparison of centering, positive offset and negative offset crank-slider mechanism, the appropriate mechanism is selected to achieve the design purpose. The selection of motor adopts a better calculation method, and the motor is selected by calculating the energy A consumed by the press in a working cycle and the energy consumption composition of each part. Through these preliminary design processes, with the help of AUTOCAD and other auxiliary analysis software, a more reasonable press can be designed.
Key words: crank press; Stamp; Crank and slider mechanism.
abstract
Crank press is a kind of metal forming machine driven by crank, which is widely used and has high production efficiency. It is suitable for sheet metal stamping, bank batching, marking and metal forming. Based on the process that metal is plastically deformed and broken into parts by exerting strong pressure on metal blank. The lathe bed can be tilted by adjusting an appropriate angle, so that printed matter, iron filings and the like can slide under the action of gravity. If the crank press is equipped with an automatic feeding mechanism, semi-automatic stamping can be realized. Crank press is one of the most commonly used cold stamping equipment, which is used as the working platform of cold stamping die. It has the advantages of simple structure and convenient use. Generally used in agricultural machinery, electric power industry, automobile and tractor industries.
This paper introduces the design process of printing machine design. First, determine the transmission scheme, then determine the size parameters and motion analysis of the press body, then select the motor, and finally design and calculate the main components of the transmission system.
In this paper, the central, positive offset and negative offset slider-crack mechanisms are deeply studied, analyzed and compared with each other, and then the appropriate mechanism is selected to achieve the goal. A better method is used to select the motor. The motor is selected by calculating the energy consumption A of the press in a working cycle and the composition of each component. Through these preliminary treatments, and with the help of AUTOCAD and other aided design and analysis software, we can design a very reasonable press.
