Abstract
Punch cutting machine is a special machine designed to improveworking efficiency, the machine is mainly used for leather cutting.
Through the analysis of the design requirements and design principles of leather blanking machine, the overall scheme is determined, the selection of transmission parts is completed, and the non-standard parts and the overall structure of the machine tool are designed. In order to realize the expected function of blanking machine, its transmission system is designed. The transmission scheme is drawn up, the transmission ratio at all levels is allocated, the design of power and motion parameters is completed, the structure is designed, and the relevant calculation andverification are carried out. According to the requirement of cutting leather by the blanking machine, the crank slider mechanism is selected to control theworking stroke, and the movement of the crank slider mechanism is analyzed. The designed Longmen leather blanking machine has the advantages of highworking efficiency, accurate movement, stable and reliable transmission, safe use and easy maintenance, meets the requirements of cutting and drying the blanking, is convenient to adjust theworking stroke, and can ensure the accurate removal of the required leather style.
