Definitions
- the invention has for its object a straightener for Straightening strips to be fed to the entrance of a press, preferably metal strips to create, in the case of simplified constructive structure of the straightening unit essential the synchronization of the adjustment of the Components serving the straightener bear are less susceptible to possible dirt and easier to maintain are.
- each crossbeam on their cover plate facing outer surface two bevels, between which and the straightener cover plate each an adjustable Wedge gate valve is arranged.
- each an adjustable Wedge gate valve By adjusting the between the traverse and the straightener cover plate arranged Wedge gate in one direction or the other can be reduce or enlarge the possible truss stroke.
- This Adjustment or adjustment of the truss stroke can be done for the one on the inlet side of the straightening unit and the one on the Traverse provided on the outlet side of the straightening unit separately make.
- the trusses in relation adjusted on the straightener cover plate, this adjustment the trusses are made in the vertical direction.
- the adjusting device is a pressure piece has that against a mounted on the straightening bear Pendulum plate rests, and the pressure piece and the pendulum plate at the mutually assigned contact surfaces in the direction of flow of the straightener with the same radius of curvature are concave or convex or convex or concave.
- the one held on the straightening bar upper straightening rollers is such a full-surface system between the mutually assigned contact surfaces of the adjusting device Thrust piece and the directional bear side Pendulum plate and thus an even application of force guaranteed by the adjustment device on the straightening bar.
- the truss stroke can advantageously be used for both trusses can be adjusted separately.
- the two should be one Traverse associated wedge slide each have a nut and be adjustable by means of a threaded spindle.
- the threaded spindle speaking has two opposite thread sections. At a rotation of the threaded spindle with a direction of rotation the two wedge slides move towards each other to or away from each other so that they are at the same vertical level arranged support surfaces for the bevels of the train the traverse assigned to them.
- the threaded spindle can also be operated manually become.
- the guidance of the straightening device can be advantageously in different straightening or positioning positions or the upper straightening rollers held on it, if the slider on the two in Direction of travel of the straightener front and rear ends each of the straightening bear preferably a hardened slider has, the corresponding areas of the frame of the straightening unit, preferably a hardened guide piece assigned.
