Description

The invention relates to mechanical engineering and is intended for the mechanical cleaning of welding wires.

Rebel grinding machines are known to have grinding wheels, as well as two cassettes, with which the rotational and translational motion of the wire is communicated to grind its surface.

The disadvantage of such machines is the inability to remove rust and adjacent softened metal layers on separate surfaces.

It is also known a device for cleaning welding wire, consisting of a body with brackets, a shaft with abrasive elements mounted on it. And clamping flanges. To the clamping flanges are suspended goods on flexible steel cables.

For quality wire cleaning, it is necessary to adjust the force of the working tool to the wire to be cleaned, depending on its diameter and surface condition. To do this in a known device. Each working tool must be equipped with a set of interchangeable goods, different from one another. By weight 2.

However, a limited assortment of weights by weight practically does not allow for the smooth control of the pressing force of the working tool to the wire. In addition, the presence of a large number of goods of different mass, as well as the presence of flexible t (cables) and their strengthening on clamping flanges, which must have additional tracks for pre-winding these cables on them, makes the design difficult

15 in service. Among the disadvantages of the known device can also be attributed to the need to hang on the cables and remove cargo from them, which takes a lot of time.

The purpose of the device is to simplify the design and maintenance.

The goal is achieved by the fact that in a device for cleaning welding wire containing a shaft, 25 planted on it freely, at least one pair of disk abrasive tools, Jtotory has grooves for the passage of cleaned wire rigidly connected with 30 disk abrasive tools

the clamping flanges and the pressing mechanism of the disk abrasive tools to the wire to be cleaned, the pressing mechanism of the disk abrasive tools to the wire to be cleaned are made in the form of single-arm levers fixed on the clamping flanges, the free ends of which are opposed in the opposite direction and supplied with weights.

In addition, weights are set movably relative to the longitudinal axis of the lever.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; on gig 3 - section EB of FIG. 1

The device comprises a housing 1 in which the shaft 2 is fixedly mounted. Two clamping flanges 3 and 4 are freely mounted on the shaft, each of which, respectively, has levers 5 and 6. The abrasive elements 7 and 8 are fixed to the flanges 3 and 4 by nuts 9 and 10. At the free ends of the levers 5 and b, loads 11 and 12 are movably mounted. The abrasive elements 7 and 8 have grooves 13 and 14 for the wire to be cleaned 15. The number of clamping flanges with abrasive elements is chosen to take into account the desired surface cleanliness.

The device works as follows.

The wire to be cleaned 15 is placed in the grooves 13 and 14 of the abrasive elements 7 and 8. Due to the fact that the clamping flanges 3 and 4 can rotate freely on the shaft 2, the force of pressing the elements 7 and 8 to the surface of the wire to be cleaned 15 is created by weights 11 and 12 set movably at the free ends of the levers 5 and 6.

The wire to be cleaned 15 is given a progressive movement, during which due to the contact between the wire and the abrasive elements the surface of the wire is cleaned. Since the levers of adjacent tools are turned in the opposite direction.

On the other hand, the elements are pressed to different parts of the wire surface, thereby cleaning the entire surface of the wire. A smooth adjustment of the force of pressing the abrasive elements to the wire being cleaned is carried out by moving loads 11 and 12 along the longitudinal axis of the free ends of the levers 5 and 6,

This device has a simpler design and is much easier to maintain.
