Description

(54) SCRAP BREAKER

The invention relates to the processing of metals by pressure and can be used for the mechanical removal of scale from a filament metal of circular cross section, for example, in production lines of wire production in the hardware industry. A device for removing scale containing a frame, a body mounted in a frame rotatably around its axis together with bending rollers, and a drive rotating the body relative to the axis of movement of the wire is known. A drawback of the device is that when the axial speed changes, the wire speeds up. rotation of the casing remains unchanged, which leads to deterioration of the conditions for cleaning the wire from scale, especially at the time of starting or stopping the line. A descaler containing a bed, a case installed in a bed rotatably around its axis and bending rolusi installed in a case are known, some of which are rigidly fixed in the case and others are installed with the possibility of radial movement perpendicular to the axis of wire 2 movement. The fact is that when operating rotary descalers for cleaning steel wire, the optimum ratio of axial dragging of the wire and rotation of the body with bending rollers is but it is such that when moving the wire length of the hull made to last three turns. Changing this ratio in the direction of decreasing it impairs the quality of wire cleaning, and in the direction of increasing it unnecessarily increases the energy consumption without improving the quality of cleaning. And at the time of starting or stopping the line, even residual twisting of the wire is possible.

The aim of the invention is to improve the quality of wire cleaning.

In order to reach the goal, the caliper is equipped with a mechanism for synchronizing body rotation and wire stripping, performed in the form of a salt wheel rigidly mounted in the stanchion coaxially with the body and the tail of the sun with the 1st gear-satellite wheel fixed on the axis mounted in the body and kinematrically associated with a roller rigidly mounted in the housing.

FIG. 1 depicts an ox sharpener, general view; in fig. 2 is a section A-A (along the axis of the drive bending roller) in FIG. one; in fig. 3 - section bB (along the axis of the gear and planetary gears), in FIG. 2.

The descaler contains a frame 1, the body 2 mounted therein with a capacity of rotation around its axis, its hollow semi-axes 3 resting on the bearing assemblies 4, is rigidly fixed. those in stash 1 (fig. 1),

In the housing 2 there are rigidly fixed bending rolts 5 and bending rollers 6 fixed on the housing 2 with the possibility of their radial 1 moving perpendicularly to the axis of the wire being cleaned 7.

In case 2, a 1 "mechanism" is used to synchronize the rotation of the case to the movement of the wire, connecting the bending rollers to the case,

The bending rollers 5 are rigidly mounted on the shafts 8 (Fig. 2, 3), bearing on the subcrop 9, mounted in glass 1O rigidly fixed in the housing 2o

A shaft 11 is mounted on the shaft 8: gear 11, located with a tapered wheel 12 mounted on the shaft 13 (FIG. 3), the shaft 13 on the rolling shaft 14 is mounted in the housing 15 fixed rigidly in the housing 2

A t & a st satellite 16 is also mounted on the shaft 13, which is located with the head of the solar sensor 17, rigidly mounted on the base 1 and is centered on the axis of motion of the wire.

The rotating body 2 is closed from the top by an enclosure 18, an eye / sneak in the vessel 19 (Fig. 1).

The descaler is working sped;

The wire to be cleaned is passed through the desalting agent and drags the mill. When driving around the 7

Bpaniemie radiates from: an ibing roller 5, each through a conical pair 11-12 transmits the rotation to the satellite gear 16, the Satellite; 1 16; rotates around its axis and runs along the sun wheel 17, pulls the body 2 behind it, which begins to rotate around wire in bearing units 4.

Due to the bending of the katash and the rollers 5 k b and its twisting in front of the entrance and unwinding at the exit of the descaler, caused by the rotation of the housing 2 ,. on noBepxiiocTH wire swelling and separation of scale. 5 A maximum wire in the descaler is created at the exit.

When changing the speed of the wire moving, respectively, from Iv econ, the frequency of the upper bending roller and, thus, the speed of the slugging beam, and changing — ie, the velocity of the body's enemy — takes place smoothly and continuously, both during operation and at the time of starting and stopping the line.

The bending gear ratio — the casing is chosen so as to provide a technologically grounded ratio of the speed of stirring the wire AND casing,

In order to avoid a possible slippage of the rogueman, the moment when the wire begins to move, the caster can be supplied with additional sun wheels and associated with them 5 rolling rollers.

The invention makes it possible to improve the conditions for cleaning wires, especially at the time of starting and stopping the litigation, and also to eliminate expensive electrical equipment previously used for wire speeds and rotation of the orpus.

From the use of the invention, an economic giJxjjeKT will constitute only 5 thousand rubles a centu- lentalist, in terms of using sync equipment,
