FIELD: mechanical engineering.
SUBSTANCE: device comprises the mechanism for locking pressed parts made of an extensible sleeve. The first power hydraulic cylinder is used for moving parts and can rotate between two vertical unmovable pillars. The pillars are pivotally connected in pair with movable vertical pillars through the top and bottom horizontal clamps. The extensible spring-loaded stop with the drive and the first hydraulic cylinder are axially aligned. The first power hydraulic cylinder receives the second power hydraulic cylinder whose rod is provided with first center and spring. One end of the spring co-operates with the piston, and other end of the spring co-operates with the face of the extensible sleeve. The extensible stop receives the second center with the stack of plate springs that is coaxial to the first center. The bottom clams are provided with a lifting-rotating device.
EFFECT: reduced labor consumption for making and simplified structure.
