Abstract
The utility model relates to the field of stamping dies, in particular to an intermittent cutting-off mechanism. The intermittent cutting-off mechanism comprises an air cylinder, an upper die seat, a lower die seat, a cylinder carrying plate arranged between the upper die seat and the lower die seat, a punch fixing plate and a punch assembly. The upper die seat is provided with an upper ejector pin and an upper ejector pin spring which are matched with each other. The lower die seat is provided with a lower ejector pin and a lower ejector pin spring which are matched with each other. The punch assembly is provided with a middle ejector rod which corresponds to the position of the lower ejector pin. The punch assembly is composed of a cutting-off punch, a punch fixing block and a punch cushion block, wherein the punch cushion block is arranged between the cylinder carrying plate and the cutting-off punch. According to the intermittent cutting-off mechanism, a traditional structure that the cylinder carrying plate and the punch cushion block are in slope contact is improved into the structure that the cylinder carrying plate and the punch cushion block are in plane contact so that the cylinder carrying plate is enabled to be only subjected to the pulling force by the air cylinder, and therefore accurate and stable movements of the cylinder carrying plate are guaranteed, and punching quality and punching efficiency are improved.
