Description

one

The invention relates to the processing of metals by pressure.

A pulling device of a multiple drawing mill is known, which contains a shaft (puck) located on a shaft mounted in a housing, a pulling drum (washer) whose working surface is made of multifaceted T |.

Such a traction device, which provides longitudinal and transverse elastic vibrations of the drawn wire, which reduce the frictional forces in the deformation areas, has a drum that wears quickly due to the uneven fit of the turns of the wire to its multifaceted working surface. In the process of dragging, the friction force between the working surface and the wire windings that rise along it, displaced by the incident thread, is unevenly distributed, which causes accelerated wear of the drum ribs.

The aim of the invention is to reduce the wear of the drum and the reduction of the rub of rubbing honey with the drum and the turns of the wire.

To do this, the drum is equipped with a vibrator, including a cam ring,

mounted on the end of the drum, and vahanmo acting with a ring spring-loaded kick NICKY installed in the case of drawing

cars.

FIG. 1 shows a drawing device of a dragging machine, a longitudinal section; in fig. 2 Dan A-A section; in fig. one,

The traction device of the dragging machine comprises a traction drum 1 mounted on a shaft. The axle oscillations mounted in the housing 2. The dd communication to the drum of axial oscillations is equipped with a vibrator, including a cup ring 3 fixed on the end of the drum adjacent to the casing 2, and rings 3 interacting with the cams located in the slots of the casing 2 and fitted with springs 5.

The number and mass of impactors 4, the height of the cams of the ring 3, as well as the rigidity of the springs 5 are determined by the kinematics of the process of drawing and the mechanical properties of the materials of the drum 1 and the wire being pulled.
