A swaging device for swaging the end of an elongated work piece such as a wire strip.

摘要

The invention relates to an upsetting device for upsetting the ends of elongated workpieces such as pieces of wire and the application of such a device in a wire-working machine for manufacturing pins. …??The prior art comprises upsetting devices with an upsetting tool which can be moved backwards and forwards by means of a slide, to which it is connected for an at all times joint movement. …??The disadvantage of this connection in short-stroke designs of the slide is that, even with the upsetting tool drawn back, there is too little space for a tool change between the slide and the workpiece to be upset, making it necessary to remove beforehand the clamping tools for holding the workpiece and then reinstall them. …??It is the object of the invention to avoid this removal and installation and to make the upsetting device operate as precisely and quietly as possible and with as little maintenance as possible. …??The solution to this object is that the upsetting tool (54) is mounted apart from the upsetting slide (12), with the ability for displacement in its direction of movement, in its own longitudinal guide (48/52, 58/50) separate from the guide (34) of the slide and that the upsetting tool (54) rests with non-positive engagement against that part (42) of the upsetting slide (12) which acts on it. …??The advantage of this solution to the object is the possibility of removing the upsetting tool as a unit together with the guide without having to remove the clamping tools in order to gain access to it. …IMAGE…
