Definitions

  • the invention relates to a profile rolling machine for producing profiles, z. B. in the form of threads on blanks.
  • the profile rolling machine comprises two rolling jaws, each having a profile, and a first drive means for at least one of the two rolling jaws for generating a linear movement of the two rolling jaws relative to each other.
  • For rolling in the thread or profile of the blank is inserted with the aid of an insertion between the two dies.
  • the insertion is offset by means of a second drive means in a linear reciprocating motion.
  • From the DE 43 40 162 A1 is a method for thread rolling or smooth rolling of sleeve or bolt-shaped workpieces, in particular of metal, known by means of jaw tools, wherein the workpiece between the jaws of a two-jaw tool is used, which has the roll profiling on the mutually facing surfaces and by relative movement of the jaws and the workpiece to each other, the rolled section is applied to the workpiece.
  • the workpiece is rotated by means of a drive means in rotating motion and fed to the inlet of the mutually parallel, non-driven rolling dies.
  • the dies are moved in opposite directions relative to each other by the rotating workpiece in engagement with the dies
  • the workpiece is released from the dies in the outlet area of the dies.
  • a thread rolling machine for rolling thread in bolts is known.
  • the carriage carrying a thread rolling jaw is guided longitudinally displaceable.
  • the carriage is reciprocated by a push rod connected to a gearbox so as to push the thread rolling jaw along a distance corresponding to the diameter of the threaded bolt to be threaded.
  • the European patent EP 1 509 348 B1 discloses an automatic rolling machine having an insertion device comprising a shuttle provided with a means for receiving a blank to be processed from a magazine and placing it in a working position between two dies.
  • the pendulum element or the insertion device is driven by a linear motor.
  • the present invention seeks to provide an alternative drive means for an insertion in a profile rolling machine.
  • the motor for driving the insertion device is in the form of a servomotor.
  • Blanks are understood to mean, in particular, bolts and sleeves.
  • profile in the sense of the invention also includes, for example, threads.
  • the claimed use of the servomotor has the advantage over the known linear motor that the servomotor can be better sealed against dirt and moisture.
  • standard products can be used for the servomotor, gearbox and encoder.
  • the servomotor is associated with a rotary encoder in the form of an electrical control or a mechanical rotary encoder for limiting the angle of rotation of the servo motor.
  • FIG. 1 It shows the essential components of the profile rolling machine 100 according to the invention. It comprises a first and a second rolling jaw 110-1, 110-2, which are moved relative to one another with the aid of a first drive device 120.
  • Blanks 200 are fed via a magazine with a feed rail 300 to the inlet of the two dies 110-1, 110-2.
  • the profile rolling machine has an inserting device 130.
  • a Einsetzschieber 134 of the insertion singles each of the dies to the next arranged blank 200 in the feed rail 300 of the other, juxtaposed blanks and pushes the blank in the inlet between the two dies.
  • FIG. 2 shows a first embodiment of the insertion device 130 according to the invention. It comprises an insertion slide 132, which is linearly reciprocally mounted in two bearings. At its end facing the feed rail 300, the insertion slide 132 is connected to the insertion slide 134. With the aid of a second drive device 140, the carriage is set in the said reciprocating motion.
  • the drive device 140 comprises a servomotor 142 whose angle of rotation via a mechanical rotary encoder 144 or a corresponding electrical control to a predetermined Angle range is limited.
  • the servomotor with the rotary encoder drives - preferably via a planetary gear 148 - a shaft 145 which has an insertion lever 146 at its end opposite to the servo motor. With the aid of the insertion lever 146, the rotational movement of the servomotor 142 is transmitted to the insertion carriage 132.
  • the insertion lever 146 shown first embodiment in the form of a horseshoe or U-shaped.
  • the insertion lever 146 forms the first part of a coupling between the second drive device 140 and the insertion slide 132.
  • the second part of the coupling forms a roller 133 mounted on the insertion slide 132, which extends transversely to the longitudinal direction of the slide 132, between the two engages both legs 146-1, 146-2 of the insertion and between these is preferably performed without play.
  • the engagement of the pin between the two legs of the U-shaped insertion lever allows the desired reciprocation in the two directions R F and R E.
  • the insertion device 130 comprises a compression spring 136, which presses the insertion slide 132 in the direction R F on the inlet E between the two dies.
  • the return movement of the insertion slide 132 with the Einsetzschieber 134 is then carried out by means of the servo motor 142 by this by the angle ⁇ about the rotation axis Z pivots counterclockwise and thereby moves the Einsetzschlitten 132 by means of the insertion lever 146 in the direction R E.
  • a tension spring could also be provided which pulls the insertion slide 132 with the insertion slide 134 away from the inlet between the rolling dies. Then, the forward movement of the carriage and the slide on the inlet E out with the help of the Einsetzhebels 146 and the servomotor should be done.
  • FIG. 3 shows a second embodiment of the insertion lever 146 according to the invention.
  • the insertion lever 146 in the second embodiment consists of only one leg 146 '.
  • the provision of the spring 136 is absolutely necessary.
  • the spring 136 at the in FIG. 3 be shown arrangement as a compression spring to move the Einsetzschlitten 132 with the Einsetzschieber 134 in the direction of inlet E between the dies.
  • the leg 146 'of the insertion lever 146 is here tangent to the side of the roller or the bearing 133, which faces the inlet E. In this way, a return movement of the carriage against the force of the compression spring from the inlet between the dies is made possible when the servo motor pivots about the rotation axis Z in the counterclockwise direction by the angle ⁇ .
  • the spring 136 could also in the second embodiment according to FIG. 3 alternatively be designed as a tension spring. Then, the leg 146 'of the insertion lever would have to abut in the second embodiment on the side of the roller or the bearing 133, which faces away from the inlet E, in order to realize the reciprocation of the carriage by an interaction with the tension spring.
