Definitions

  • the invention relates to a straightener for wire-shaped, multi-wire or tubular straightening material with a plurality of rotatable straightening rollers arranged in two parallel planes, the axes of rotation of which are stored in cassettes which are arranged in a housing holder.
  • the cassettes of both levels can be immovable or the cassettes of one level or both levels can be arranged to be adjustable by means of an adjusting device.
  • the cassettes are rectangular and have grooves in which pins engage, on which they are guided in a straight line.
  • the ends of the pins lie in grooves in the upper and lower cover plates of a multi-part housing holder, which makes it possible to clamp the cassettes against one another.
  • the cassettes of the one level are arranged in such a way that they are each supported against a spring which presses the cassette against an opposing feed screw. By screwing the delivery screw in or out, the cassette and thus its straightening roller can be adjusted against the straightened goods or away from the straightened goods.
  • the object of the invention is to improve a straightening apparatus of the type mentioned in such a way that, on the one hand, the cassettes can be exchanged without great effort and, on the other hand, a high level of precision in straightening and long tool life are ensured, the play required being minimized and the precision of reproducible setting should be increased.
  • the cassettes with a hollow cylindrical housing make it possible to arrange them easily replaceable in easily produced, precisely positioned fitting bores with practically no play, which ensures high reproducible accuracy and simple production.
  • the straightening apparatus shown in FIG. 1 has straightening rollers 1 arranged in two parallel planes A and B, the axes of rotation 2 of which are rotatably mounted in cassettes 3.
  • a cassette 3 consists of a hollow cylinder 3 ', which is closed on one side by a cover 4 and in whose open end the axis of rotation 2 carrying the leveling roller 1 is inserted.
  • the axis of rotation 2 is supported for axial support by means of a ball bearing 5 at the end of the cassette 3 on the cover side, the track for the balls 6 being executed in the hollow cylinder 3 'on the one hand and in the axis of rotation 2 on the other hand.
  • needle bearings 7 are arranged in the upper part of the hollow cylinder 3 'directly between the inner wall of the hollow cylinder 3' and the axis of rotation 2.
  • the straightening roller 1 has on its underside facing the cassette 3 an annular groove 8 which is intended to receive the upper open end of the hollow cylinder 3 '.
  • This arrangement produces a labyrinth seal which enables the use of a straightener with such cassettes, even in damp and dusty rooms. This protects the bearings of the axis of rotation from dirt, which increases their service life. Due to the direct arrangement of the thrust ball bearing and the radial bearing, i. H. without outer and inner ring, the game is minimized.
  • the lid 4 of the cassette 3 can also be made in one piece with the hollow cylinder 3 '.
  • the connection of the straightening roller 1 with its axis of rotation 2 can in any way, for. B. also be done by gluing, which makes it possible to remove the straightening rollers 1 from the axis of rotation 2 without significant effort and to replace them by new straightening rollers 1 or by straightening rollers 1 with other diameters and / or recesses, ie it is not necessary, but possible, replace the entire cassette 3.
  • the cassettes 3 are arranged in the plane A in a housing holder 9 in fitting bores 10 executed therein, the diameter of which is selected such that the hollow cylindrical cassettes 3 can be inserted without play. Since such fitting bores 10 can be carried out very precisely and easily, this ensures a high level of precision in the arrangement of the cassettes 3 in a simple manner, even with every exchange.
  • the cassettes 3 are arranged in fitting bores 10 ′ in the plane B, said bores being embodied in a guided movable sliding block 11.
  • the sliding block 11 has a threaded bore 12 into which an adjusting spindle 13 engages. The free end of the adjusting spindle 13 is guided through a wall 14 of the housing holder 9 and carries an adjusting knob 15.
  • the adjusting knob 15 is axially movable on the adjusting spindle 13, but is non-rotatably arranged. Inside the adjusting knob 15, a helical spring 16 is arranged on the adjusting spindle 13, which is supported at one end against a projection of the adjusting knob 16 and at the other end against a disk 17, which is attached to both the adjusting knob 15 and the adjusting spindle 13, e.g. B. is fixed by a screw 18. By this arrangement of the coil spring 16, the adjusting button 15 is thus biased against the wall 14 of the housing holder 9.
  • the wall 14 has a recess in the area of the contact surface of the adjusting knob 15, in which a rubber disk 19 is arranged.
  • the rubber washer 19 serves, in addition to the pressure by the helical spring 16, to increase the friction, so that the adjusting button 15 cannot be adjusted independently even when there are strong vibrations during the work of the straightening apparatus.
  • a friction-increasing material e.g. B. also a plastic, leather or the like can also be applied directly to the adjustment button 15 and / or directly on the wall 14.
  • B snap-in connections (not shown) be provided.
  • the friction connection can be released, this enables an easy and thus also a very precise adjustment of the adjusting spindle 13 and therefore also of the sliding block 11. If no exact adjustment is necessary, the axial adjustment of the adjusting knob 15 can also be dispensed with; it is then only necessary to apply more force to adjust the adjusting knob 15 in order to overcome the frictional connection.
  • any known axial guidance of the sliding block 11 and the corresponding choice of the pitch of the thread can ensure a very precise, easily re-adjustable position of the cassettes 3 and thus the leveling rollers 1 of the plane B.
  • the bearings of the axis of rotation 2 can be periodically supplied with a lubricant, e.g. B. by a closable drilling system (not shown) in the axis of rotation 2 when the straightener is at a standstill. It is also possible to provide a lubricant depot with outlet openings to the bearings 5, 7 within the wall of the hollow cylinder 3 ', which can optionally also be connected to a supply line system within the housing holder 9 (both not shown).
