Definitions

  • the invention relates to a straightening apparatus 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 mounted in two body parts forming a basic body and being movable relative to one another, the body parts being arranged on guides and having a locking mechanism.
  • the known locking mechanisms have an eccentric which is connected to a lever and, depending on the force applied by hand, holds the two body parts which are movable relative to one another in a closed position due to frictional forces. To open it, the lever is moved into an open position and the two body parts have to be brought into their open position by hand or by means of a tool, which on the one hand is complex and on the other hand also entails the risk of damage.
  • the object of the invention is to improve a straightening apparatus with the features of the preamble of claim 1 in such a way that a zero position once defined can be maintained even over longer periods of time without the need to readjust or replace parts.
  • the invention provides a straightening apparatus which can only assume two positions, a defined open position and a defined closed position in the zero position, which is clearly defined by the latching of a releasable latching connection.
  • the straightening apparatus shown in Fig. 1 has a base body 1, which consists of two body parts 2 and 3.
  • the two body parts 2 and 3 are arranged on two parallel guide pins 4, which serve as guides.
  • the guide pins 4 are firmly connected to a body part 2 or 3, while the other body part 2 or 3 is slidably arranged on the guide pin 4.
  • the guide bolts 4 are each arranged or fastened in a through bore 5 penetrating the base body 1, the bore 5 in the body parts 2 and 3 each having an extension 6, 6 'in which a helical spring 7 is arranged on the respective guide bolts 4 which is supported against the ends of the extension 6, 6 '.
  • the coil spring 7 is covered by a protective sleeve 8 in the exemplary embodiment.
  • the protective sleeve 8 is dimensioned such that on the one hand it does not hinder the abutting of the body parts 2 and 3 and on the other hand completely covers the helical spring 7 and accordingly also the guide pin 4 in the open position of the straightening device, so that both the spring 7 and the guide pin 4 and their trajectories are protected from contamination.
  • the body part 2 has an odd number of straightening rollers 9 and the other body part 3 has an even number of straightening rollers 9, which are arranged at a gap and at equal intervals from one another.
  • An eccentric 10 in the form of a disk is rotatably mounted on both side surfaces of the body part 3.
  • the eccentric 10 is articulated via a pull rod 11 articulated on it by means of a fastening pin 12 on the body part 2 by means of a fastening pin 12 '.
  • the eccentrics 10 on both sides are connected in the exemplary embodiment to a common operating lever 13, which is designed as a transparent protective hood, which completely covers the straightening rollers 9 from above in the closed position of the straightening apparatus.
  • cover plates 14, 14 ' are arranged on the body parts 2 and 3, which have a height which slightly exceeds that of the straightening rollers 9 used in their working position, and on one of which the operating lever 13 - the protective hood - is in the closed position of the Straighteners supports.
  • the guide pin 4 each has a transverse groove 15 on its lower side directed towards the bottom of the straightening apparatus, which transverse groove for receiving one of the free ends 16, 16 'in each case centrally by means of a screw 17 in a recess in the bottom attached leaf spring 18 is used.
  • the leaf spring 18 is biased such that it presses against the transverse groove 15 and engages in it, i. H. forms a defined locking connection.
  • the straightener works as follows.
  • the straightening apparatus is in a defined open position by means of the coil springs 7, the operating lever 13 (the protective hood) being almost vertical and allowing unimpeded access to the straightening rollers 9 and for introducing a straightening good.
  • the leaf spring 18 is located outside the transverse grooves 15 of the guide bolts 4.
  • the operating lever 13 is pivoted from the practically vertical open position into the horizontal position, the two Body parts 2, 3 due to the eccentric and tie rod connection against the force of the coil springs 7 are moved towards each other until the leaf spring 18 engages in the transverse grooves 15 in the guide pin 4. In this locking position, the two body parts 2, 3 and thus also their straightening rollers 9 are arranged in a defined zero position.
  • the protective hood can also have lateral transverse walls 22 with a slot 23 or a bushing or eyelet for guiding or for the passage of a straightening good. This creates an almost closed straightening room that is largely protected from external contamination.
  • the leveling room can be connected to a vacuum source (not shown), the suction openings in the direction of movement of the leveling material preferably being in the immediate vicinity behind the respective contact point between the leveling roller and leveling material are arranged.
