Description

one

The invention relates to the field of wire processing by the method of plastic deformation and is intended for use in enterprises engaged in the manufacture of electrical and radio equipment.

- A device for straightening a lengthy material is known, containing a rotatably mounted housing, a swinging three-arm arm in the housing, on one arm of which a finger is rigidly mounted, and on the other two correct rollers, guide rollers mounted in the housing, and a clip with a fork are placed mounted concentric to the body with the possibility of axial movement and in contact by means of a plug with a finger of the three-arm lever 1.

The disadvantage of the existing device is limited technological capabilities due to the lack of control of the schaga between the correct rollers, which is necessary to create optimal conditions for straightening wires of different diameters and mechanical properties.

In order to expand technological capabilities, the correct rollers are fixed on the arms of the lever by means of eccentric axes, on which gears are rigidly fixed, connected to each other through an intermediate gear mounted on the swing axle of the three-arm lever. This makes it possible to adjust both the deflection boom and the pitch between the correct rollers depending on the diameter and mechanical properties of the material.

FIG. 1 shows the device, a general view; in fig. 2 is a section AA in FIG. one.

The device consists of a body 1, made in the form of a rotating drum, in which two guide rollers 3 are mounted on fixed axles x 2, and on a semi-axis x 4 there is a swinging three-arm arm 5 with correct elements made in the form of rollers 6 mounted on eccentric axes 7, and a finger 8 interacting with a plug 9 mounted for movement along the axis of the housing. On axles x 7, gears 10 are rigidly fixed, which are interconnected by an intermediate bristle 11 mounted on the swing axis of a three-armed arm. The device works as follows. When axially moving relative to the housing 1, the fork 9 rotates with the help of a finger 8 a swinging three-blade arm 5 with the correct rollers 6, as a result of which the deflection arrow of the straightened material 12 changes.

When rotated with the help of axis 4, the intermediate shchestren 11 and 10 are rotated together with the axles 7. At the same time, the eccentrically located right rollers converge or diverge, i.e. the pitch between them changes. The device for straightening lengthy material can be installed on a special correct or correct cutting machine, as well as on universal equipment.
