Abstract: Prior to the forming of bar material, without creating internal stresses, on transverse transport presses, bars are sub-divided into sections of equal volume, the end-pieces of each bar having to be discarded before further processing. To provide for the automatic and material-saving discarding of the end pieces, two light barriers are installed in the feed zone of the bars, the distance (a) between these light barriers being newly stored in a microprocessor as each bar is fed in, and this distance being converted, by calculation, to three further distances (b, c, d). By reference to these data, the microprocessor controls the discarding operation, with one, or at the most two, section lengths being discarded per bar, according to whether the interface between two successive bars is located in the central region of the section length in question, or in one of its two end-regions.

Abstract: Incorporated with a heading machine for cutting continuous wire stock into required lengths for subsequent heading operation, the shearing apparatus includes a movable shear element against which is clamped a wire length to be cut off and which is reciprocated with respect to a fixed shear element. For reciprocating the movable shear element, which is carried by a slide, there is provided an actuator lever having a pusher member operatively mounted on its free end. The pusher member pushes the slide via an abutment thereon during the forward or cutting stroke of the movable shear element and, during the return stroke, via an air cylinder secured to the slide and held under constant supply of pressurized air. Upon completion of the return stroke, the air cylinder retracts to permit the actuator lever to pivot through an additional angle, with the consequent creation of a space between pusher member and abutment, so that the actuator lever can be pivoted back unloaded through the additional angle before commencing the forward stroke of the movable shear element.

Abstract: The assembly is for shearing rod sections with a movable cutter carriage carrying a shearing blade between a resting position and a shearing position. A reciprocating impact head is used to drive the cutter carriage. The impact head is moved into contact with an adjacent end of the cutter carriage to effect motion of the cutter carriage to the shearing position. The cutter carriage is biased toward the impact head and the resting position to effect the return stroke motion of the cutter carriage. The contact of the impact head with the adjacent end of the cutter carriage is broken on completion of the return stroke to draw the impact head a predetermined distance back to a starting position from which the impact head is ready to strike the adjacent end of the cutter carriage with considerable momentum upon the starting of the next shearing cycle.

Abstract: A control system is disclosed for a hot forging machine which is supplied with lengths of stock. The system provides automatic rejection of workpieces cut from the rearward end of one length of stock and the forward end of a subsequent length of stock. The system includes a sensor which laterally deflects the rearward end of a length of stock as such rearward end approaches a control point to produce a signal to reset the system. As the forward end of the subsequent length of stock passes the control point, a second signal is generated to actuate the stock movement measuring system. Stock movement is measured by a measuring roller which engages and is turned by the stock as it moves toward the cutter. The rotation of the measuring roller drives a pulse generator which supplies a signal to a counter. When a first predetermined number of pulses have been generated following the movement of the forward end of a length of stock past the control point, it is known that a first predetermined length has passed and rejection of workpieces is established. When a second predetermined number of pulses have been counted to indicate passage of a second predetermined length, the normal cutter operation is re-established to terminate rejection of workpieces.
