Forcing device for axially forcing a pin from a bore

摘要

The invention relates to a forcing device for axially forcing a tapered pin from a tapered bore via a threaded stem attached to the tapered pin. The forcing device consists of a basic body which surrounds the workpiece in a U shape and into one leg of which a pressure body can be screwed. According to the invention, this pressure body is of two-piece design with two parts which lie concentrically one inside the other and can be driven separately; specifically it consists of a sleeve-shaped clamping screw with knurled collar and a pressure spindle arranged in the interior of the clamping screw. The forcing device can first of all be secured to the workpiece with the clamping screw in such a way that it is locked against tilting. With the pressure spindle to be subsequently actuated, the forcing pressure can then be produced and the tapered pin can be forced out of the tapered bore. The pressure spindle can be designed essentially like a socket spanner with socket, shoulder and rotary shank. Here, the forcing pressure is produced with the retaining nut and the threaded stem of the tapered pin itself by slackening and forcibly turning back the nut - anticlockwise procedure.
