Description

1

The invention relates to mechanical engineering and can be used for the mechanical cleaning of welding wire from an oxide film and rust of a rank. all areas of industry where welding with filler wire is used.

The purpose of the invention is to increase the productivity and quality of wire cleaning.

Figure 1 shows a device for mechanically cleaning a wire; FIG. 2 is view A of FIG. 1; on fig.Z - section bb-on figure 1.

The device comprises a base 1, on which the sleeves 2 and 3 are fixed, with a hollow spindle 4 mounted on the bearings and a detachable shaft 5 rotating around a common axis and kinematically coupled to each other by means of a planetary gear train. The sun gear gear 6 is connected to the race 2 and also serves as a bearing cap, the satellite gear 7 is mounted on the shaft 8 rotating on the bearings mounted in the driving spindle 4 and fixed to it by the cap 9, and the central wheel 10 is fixed on the end of the split shaft 5. The detachable shaft 5 consists of two parts interconnected by a threaded connection, by means of which a cleaning tool 11 is simultaneously attached to it with an outer working surface (for example, a iglo-cutter).

The driving spindle 4 is a welded structure consisting of two sleeves rigidly interconnected by a strap 12, One of the sleeves is connected to the wedge sheave 13, and the second with a flange 14.

In the radial grooves, the brackets 12 are installed with the possibility of adjusting the guide 15, which is a round rod with a central opening made equal to the diameter of the wire to be cleaned, which have thrust collars and tips at the ends. In the middle part of the guide, a groove is cut with an emphasis across the width, which serves to hold the wire on the guide when pressed against the cleaning tool. Stop height less than diameter

cleaned wire. The shaft 5 is made detachable in order to reduce the loss of working time when replacing a worn cleaning tool.

To expand the possibilities of using the device as a cleaning tool, abrasive wheels and the like can be used instead of a needle cutter. tool with outer work surface.

The device works as follows.

The wire to be cleaned is passed through the left centering die 16, the guide 15 and the right centering die 17 and is fixed to the winding drum (not shown). After the rotation of the winding drum is communicated by means of a V-belt transmission, the driving spindle 4 and the separable shaft 5, which is kinematically connected to it through a planetary transmission, rotate, i.e. pulling the wire being cleaned through the cleaning tool and simultaneously moving the wire in a circular orbit.

To increase the relative speed of movement of the wire being cleaned relative to the working surface of the cleaning tool, which allows to increase the wire drawing speed (performance), the forward ratio of the planetary gears is chosen so that in one revolution of the driving spindle 4 with the wire being cleaned around the cleaning tool, the cleaning tool performed three turns, and relative to the wire being cleaned - two turns.

If necessary, this gear ratio can be increased or decreased. During the rotation of the cleaning tool 11 and the wire to be cleaned relative to the cleaning tool, an intensive cleaning of the wire occurs. The pressing force of the wire being cleaned to the cleaning tool 11 is carried out by adjusting the guide 15 in the radial grooves of the bracket 12 of the driving spindle 4. When the cleaning tool 11 is worn, a similar adjustment is made.
