Description

1238925

The invention relates to the field of welding, and more specifically to devices for removing burrs, formed by npi butt welding of wire, and can be used, for example, to remove burrs from butt-welded wire before a drawing mill or winding device.

The purpose of the invention is to improve the quality of deburring by ensuring that the deblocking is flush with the surface of the wire that is not deformed during the welding process.

Figure 1 shows the device, a general view; figure 2 is a view of And figure 1; figure 3 - node clamping wire eccentric.

The device for removing burrs during butt welding of a wire contains a drive cutting disk 2 mounted on Stalin 1 and movable in the bed guides in the horizontal direction perpendicular to the wire. lock caliper 3, having the ability to be fixed by means of screw 4 and handwheel 5. Caliper 3 carries the carriage consisting of skewed skulls 6 passed through its holes, on which ends the clamp 7 is fixed in cylindrical holes x split sleeves 8, having through longitudinal grooves, through which eccentrics 9, planted on axis 10 can be rotated. The sleeves 7 of the sleeve 8 have slots 11 for the passage of the wire. The eccentrics 9 are equipped with a handle 12 dp of their rotation. Position 13 marked buttwelded wire.

The device works as follows. /

The welded portion of the wire 13 is placed between the yokes 7 by winding the wire in the slot 11 of the sleeves 7 and the sleeves 8. Then, turning the handle 12 in different directions, press the eccentrics 9 to the bottom surface of the sleeves 8, simultaneously tensioning it. Then the place of welding the wire by shifting the pins 6 relative to the support 3 is retracted to the side relative to the axis of the disk 2. The support 3 with the carriage and. the wire 13 fixed therein by turning the handwheel 5 is brought to the rotating disk 2 until a spark emerges from the contact of the disk 2 with the wire 13. The support is fixed in such a position with a screw 4, so that when you remove the burr, the cut is made to the level of the initial wire diameter neither wear of the disk 2 and the original diameter of the wire 13. Then the carriage is returned to align the welding point with the axis of the disk 2. The shaft is turned together with the sleeves 8 around the axis until the bur is completely removed around the weld.

The use of the device allows processing the welded place flush with the diameter of the original wire, which does not weaken the welding position, and contributes to an increase in productivity of, for example, a drawing machine by reducing the time to eliminate wire breakages at the welding site.
