Description

one

The invention relates to the processing of metals by pressure, in particular to devices for cutting pipes and rolled products.

The purpose of the invention is to increase the reliability of the device for cutting pipes and rolled products.

FIG. 1 shows a device for cutting pipes and rolled products; general view; on fi1. 2 shows section A-A in FIG. one.

The device for cutting pipes and rolling consists of a shock knife 1 mounted between the plates of the drive shaft 2 mounted on bearings 3 in the housing 4. To balance the drive shaft 2 between the plates on the opposite side of the shock knife 1, a counterweight 5 is mounted. On the same shaft as the impact knife 1 a rubberized pulley 6 is installed. On the inside of the cover of the housing 7, a dovetail tail spring sector 8 is installed by connecting the outer surface equal to half the circumference

The device for cutting pipes and rolling works as follows.

From the electric motor 12, the drive shaft 2 is driven into rotation, while the impact knife occupies a stable position (Fig. 2). When the eccentric shaft 9 rotates at an angle of 90 °, the spring-loaded sector 8 moves to the zone along which the rubberized pulley 6 rolls along the lateral surface of the spring-loaded sector 8, while the impact knife I rotates through an angle of 180 °, and its inertia and under action of centrifugal force, as a result of this, it does not go through a cutting zone at high speed. After this, the impact knife 1 takes a stable position (Fig. 2) due to the displacement of the center of gravity, and the spring-loaded sector 8 returns to its original position under the action of the spring 10, at which the rubberized pulley 6 does not contact the rubberised 1-kV 6. Spring-loaded spring 8 The random highlight 8 moves in one direction with the help of the eccentric shaft 9, and returns 10D by the action of the spring 10. The eccentric shaft 9 is mounted on the cover of the housing 7. In the housing 4 a fixed blade 11 is fastened.
