摘要:
A process for producing Phillips-head screwing tools or the like, especially in the form of bits, by cold forming from a workpiece section (W) cut to length from a profiled rod. In order to produce bits of high precision, that the workpiece section (W) which is developed at one end with a hexagon profile and adjoining it with a section with supportable front end (16) is introduced, with axial spring-loaded support, into a press tool (P), whereupon the cheek plates (51) of this press tool (P) produce the Phillips-head shape or the like by a displacement towards the center which is controlled by a conical envelope surface (55) which tapers towards the front end (16).
摘要:
A device on a slider crank for generating a motion relative to the a slider (press ram 5) of a part (ejecting spring pin 6) mounted on the slider, wherein such motion is taken off a crankpin (1) upon rotation of the crankpin around a crankshaft axis and transmitted along a pushrod (connecting rod 4) to the part (ejector spring pin 6). For this purpose, revolving parts (wheel 22, 34, 38; disk 98, 100, belt 102; disk 142, 148, belt 150) transmit rotary motion on the connecting rod (26, 28; 144) (FIG. 1).
