Definitions

  • This invention relates to a rod switch and, more particularly, to apparatus arranged to cause the rolled product of a rolling mill selectively to enter one of a plurality of paths.
  • the device usually used consists of a switch pipe which is swingable in a horizontal direction so that its exit opening can be brought alternately in front of the inlets of two guide members lying side by side.
  • the drive for the swinging movement is so designed that the switch pipe, during the passage of the respective strips and for a short time before the passage through the rear end of the rod, is pressed with an increasing control pressure against the rod which is running through it in the direction of the other position of swing.
  • the pipe is pushed with a jerk into the other position.
  • a further object of the present invention is the provision of a rod switch of simple and rugged construction for introducing the front ends of lengths of rolling mill product into desired paths.
  • a still further object of this invention is the provision of a rod switch in which the danger of a cobble due to malformed rod rear end is eliminated.
  • FIG. 1 is a plan view of a rod switch embodying the principles of the present invention
  • FIG. 2 is a vertical sectional view of the invention taken on the line IIII of FIG. 1,
  • FIG. 3 is a vertical sectional view of the invention taken on the line IIIIII of FIG. 2, and
  • FIGS. 4, 5, 6 and 7 are schematic plan views of the apparatus showing the sequence of operation.
  • this invention provides for the arrangement between the switch pipe and the receiver of a swingable control part which is capable of swinging relative to the switch pipe.
  • the control part is connected to the switch pipe by pressure devices which oppose the adjusting forces of the rod passing through it, so that, immediately after a rod passes through the control guide, it will move into axial alignment with the switch pipe and will be directed toward the other receiver opening.
  • the advantage of this arrangement is that the rods can pass through the guide system without interruption and can be introduced safely into the corresponding one of the two receiver openings.
  • the guide areas of the control guide are formed in the shape of a funnel with the enlargement in the direction of the inlet side.
  • the control guide is connected to the switch pipe by an elastic means which, in the preferred example, is a leaf spring.
  • the switch pipe can be moved during the passage of a rod into a position in front of the next receiver opening and to receive the next rod. This can be done without moving the rod too far out of its direction of flow because the rod adapts itself to the running direction because of the flexible connection between the switch pipe and the control guide.
  • the end of the rod has left the control guide, it flips back to a position of alignment with the switch pipe because of the force of the spring, so that the next rod can enter the proper receiver opening only a fraction of a second later.
  • the rod switch indicated generally by the reference numeral 10
  • the receiver is provided with a first opening and a second opening 16 leading, respectively, to pipes 17 and 18 which, in the preferred embodiment, lead to rod reels (not shown).
  • the forward end of the switch pipe 13 rests on a support 19 having adjustable stops 21 and 22. It is provided with a motor 23 for bringing about swinging movement from one extreme position to another. When it rests against the stop 22 it is directed axially into the opening 15 of the receiver 12; when it is resting against the stop 21 it is directed toward the opening 16 of the receiver 12.
  • the switch pipe 13 is pivotally mounted some distance rearwardly on a vertical pivot (not shown) for horizontal motion- At the exit end, the pipe has mounted on it the control guide 14 which is swingable relative to the switch pipe 13 but only in the horizontal plane.
  • Mounted on the exit end of the switch pipe 13 is a sleeve 24 having abutments 25 and 26in which are mounted the ends of elongated leaf springs 26 and 27.
  • the sleeve 24 is provided adjacent the control guide 14 with further abutments 28 and 29 which also restrain the leaf springs 26 and 27.
  • Extending from the upper and lower parts of the control guide 14 are abutments 31 and 32 to which are locked the other ends of the springs 26 and 27.
  • the control guide 14 is separated from the end of the switch pipe 13 and the springs 26 and 27 constitute its sole support. Passing axially through the control guide 14 is a passage 33 which, in the preferred embodiment, is a surface of revolution in the form of a cone, having its large end adjacent the switch pipe 13 and its small end adjacent the receiver 12.
  • the rod pressure thus moves the control guide 14 so that, even though the larger end of the passage 33 is still in substantial alignment with the exit end of the switch pipe 12, the smaller end of the passage 33 is directed toward the opening 16 of the receiver, so that, as is obvious in FIG. 5, the rod 34 passes through the elements with a minimum of bending.
  • Apparatus for alternately introducing bendable rolling mill product which arrives one length after the other through a switch pipe and enters two receiver pipes arranged adjacent one another, wherein the switch pipe can be directed toward one receiving pipe during the running of the rod through the other receiver pipe,
  • control guide which is swingable relative to the switch pipe and is swingable by the forces of the rod passing through them, wherein the control guide is arranged in such a Way that immediately after the termination of the rod force the control guide adjusts itself to be directed in axial direction to the switch pipe which has already arrived in front of the next receiving pipe.
  • control guide is connected by elastic members to the switch pipe.
  • control guide has a passage for rod which has a larger diameter in the direction of the inlet side.
  • a rod switch comprising (a) a receiver having two openings located in closely adjacent relationship,
  • a rod switch comprising (a) a receiver having two openings leading to rod pipes located in closely adjacent relationship,
  • control guide is provided with a passage in the form of a surface of revolution having a large diameter at the end adjacent the switch pipe and a relatively small diameter adjacent the receiver.
