Abstract

Deburrer for butt-welded wires has a rotating grinding wheel which contacts the periphery of the wire to be deburred and is guided both in a circle about the wire and also parallel to it. Preferably the wire is held in a self-centering clamp and the driven wheel is on a rotatable bushing which is rotatably mounted or guided in a helical motion coaxial to the wire. The motor driving the wheel is mounted the bushing, which is mounted on a pipe receiving the wire and is guided by a helical groove on the pipe periphery. Time and power requirements and environmental effects are minimal, and accidents are prevented.

that a rotating grinding wheel in contact with the burr to be deburred is used, which is guided both in a circle around the bratt and parallel to it. In this way, manual work can be switched off and, by appropriate covering of the zintegrated border, there is a possibility of accidents and a harmful and disruptive influence on the environment if there is little. Time expenditure can be prevented _t

The device shown has a self-centering one Clamping device 1, the mode of operation of which, for example, in the case of a centrally clamping "clamping - odei vice is known, and therefore does not require any further explanation here. This Spanrivorrichtung 1 is on - '. A plate "~ ■ -" 5 and has interchangeable jaws 2 with built-in prismatic grooves 3 (Pig * 4), which make it possible to use curly wires of 4 different diameters to be clamped centrically.

On the opposite side of the plate 5, a bracket 6 is fastened at the level of adjustment by means of adjusting screws 7. A tube 8 with a slot 25 directed upwards and widened to the rear is attached to the top of the console. .Am the circumference of the Hohres is a helical groove 9 with. äsESKxBxHiteHgsiH several.

package 17 picks up and adjusts itself with pre-tensioning so supported against the bridge 18 attached to the bushing 1o. By adjusting the nut 19, the Swivel the grinding motor 14 around the pivot point 12 in the direction of the wire plane or in the opposite direction so that the Grinding wheel 2o depending on the wire diameter with its face on the wire 4 is applied.

This adjustment only has to be made when changing to a different diameter or after a certain amount of wear and tear on the grinding wheel 2o can be made. The wire to be deburred 4 is clamped in the jig 1 that the burr 21 laterally touches the outer side surface of the grinding wheel 2o. When the lid 22 of a hood is pivoted down the grinding motor 14 is switched on via a limit switch 23. By about a quarter turn on the handwheel 24, which is limited by a stop 26, the disc grinds 2o in a helical movement around the wire axis from the edging burr 21. The slope of the helical Hat 9 is chosen so that the grinding movement entire face width of the grinding wheel 2o experiences even wear.

During this grinding movement, the wire 4 is enclosed in the tube 8 and by the rotatable sleeve 1o. By reverse The direction of rotation of the grinding motor 14 is in its Starting position retracted by a stop
