Patent number: 4070723Abstract: A method for automatically controlling the operation of a rod-working apparatus of the type including a rod-feeding unit which feeds towards a cyclically operating work tool a certain length of rod per work cycle of the tool. There are selected a minimum and a maximum distance through which a rod to be fed towards the work tool is to be permitted to advance per work cycle of the tool. A rod is fed towards and into the range of operation of the tool. The actual distance advanced by the rod during a work cycle of the tool is determined. It is also determined whether the actual distance of advancement falls within the range defined between the preselected minimum and maximum distances. When the actual distance falls outside such range, operation of the rod-feeding unit is terminated.Type: GrantFiled: September 29, 1972Date of Patent: January 31, 1978Assignee: Hagenuk Vormals Neufeldt & Kuhnke GmbHInventors: Hans Jurgen Jess, Karl-Heinz Friederichs

Patent number: 4068546Abstract: A screw machine has a displaceable headstock and is provided with a pusher rod having at its front end a chuck that engages the rear end of a bar that passes axially through the headstock. This pusher rod is connected to a chain drive at least one of whose sprockets is connectable through a clutch to a gear meshing with a rack carried on the headstock. When this clutch is closed the headstock and pusher rod are positively locked together for joint displacement. During feed operations the two are disconnected so that the pusher rod can displace a new length of bar through the headstock, and the pusher rod may be arrested during backward displacement of the headstock in order to allow the chuck thereof to get new purchase on the bar.Type: GrantFiled: July 28, 1976Date of Patent: January 17, 1978Assignee: Hagenuk Vormals Neufeldt & Kuhnke GmbHInventor: Johannes Werkmeister

Patent number: 4068545Abstract: A screw machine has a headstock provided with an openable and closable chuck rotatable at high speed and having a throughgoing aperture of cross-sectional shape complementary to that of a bar to be machined in the screw machine. A feed apparatus for this machine comprises means for detecting the rotational speed of the chuck and for generating a speed output when the rotational speed lies within a predetermined range. In addition, a pusher is provided which only advances the bar into the aperture of the chuck after generation of the output. This pusher is engageable with an abutment that is only displaced out of its way when the speed output is generated. Furthermore the apparatus generates a position output when the bar is properly in place and has a timer which withdraws the bar from the chuck if within a predetermined time limit after generation of the speed output the position output is not generated, indicating that the apparatus is unable to load the bar.Type: GrantFiled: July 28, 1976Date of Patent: January 17, 1978Assignee: Hagenuk Vormals Neufeldt & Kuhnke GmbHInventor: Holger Scheler
