Definitions

  • the invention relates to an actuating device for the pressure rollers and / or deflection shells of reels, in particular underfloor reels, in hot strip mills, in which each, for example by a Genlenk square, supported and guided roller and / or shell support for closing and opening the pressure roller unit relative to Has p eldorn can be operated by a combined pneumatic hydraulic actuator.
  • Belt reel, especially underfloor reel, in hot strip mills are equipped with a pressure roller unit, which usually comprises three or four pressure rollers and / or deflection shells, each of which has its own adjusting device.
  • a large-volume pneumatic cylinder is usually used to actuate each adjusting device when the pressure rollers and / or deflection shells are turned on and swiveled away.
  • hydraulic shock absorber cylinders have been used for actuating devices for the pressure rollers and / or deflection shells of underfloor reels, which to a certain extent are combined pneumatics - Form hydraulic actuator.
  • hydraulic shock absorber cylinders differ from an ordinary hydraulic cylinder in that they contain a piston-shaped accumulator in their piston rod. Sealed nitrogen gas is located behind one side of the accumulator piston movable in the piston rod, while the other side of the accumulator piston can be acted upon by the hydraulic pressure acting on one side of the working piston displaceable in the hydraulic cylinder.
  • the relevant side of the piston displaceable in the hydraulic cylinder is pressurized with hydraulic fluid, the accumulator piston within the piston rod is brought into a position in which the pressure of the hydraulic fluid and the pressure of the nitrogen gas are balanced.
  • the purpose of the invention is to remedy this defect. It is therefore the goal of her to create an actuating device of the generic type with which not only the positioning of the pressure rollers against the coiler mandrel before the entry of the strip start and the pivoting of the same after the strip entry securely enables, but also for the pivoting of the pressure rollers the circumference of the bundle before the end of the band allows a pre-positioning during the winding phase of the band, that the remaining stroke for applying the rollers is carried out at a reduced speed, and thus their impact energy against the belt bundle can be limited to a minimum.
  • this object is basically achieved by the characterizing features of the first claim.
  • an actuating device designed in this way is that all the primary movement sequences are carried out by the hydraulic cylinders and therefore the hydraulic fluid allows an adjustable, constant actuating speed by means of an adapted control, regardless of the load changes.
  • the pneumatic cylinder In the applied state of the pressure rollers, while the tape is running in, the pneumatic cylinder is - as before - in operation, whereby it causes an approximately constant spring rate because, due to the high compressibility of the air and the large volume connected downstream, there is no noticeable increase in force on the cylinder when the pressure rollers are displaced .
  • a further feature of the actuating device, which is essential to the invention, is specified in the second claim. This not only creates a minimal overall length for the pressure cylinder, but also ensures that the primary actuating movements are carried out exclusively by the hydraulic cylinder and that the specified spring rate of the pneumatic cylinder is maintained in any case.
  • the mandrel 1 of an underfloor reel is assigned a pressure roller 2 and a deflection shell 3, which are seated on a common roller and / or shell carrier 4.
  • the roller and / or neck holder 4 is supported and guided by a four-bar linkage 5, the two rocking levers 6 and 7 of which are mounted in a fixed frame 8 such that they can be pivoted to a limited extent about the axes 9 and 10.
  • the piston rod 12 of a pneumatic hydraulic actuating device 13 engages on the rocker arm 6 via an arm 11, which in turn is supported on a bracket 14 of the stationary frame 8.
  • the pneumatic hydraulic actuator 13 in turn consists of a pneumatic cylinder 15, in the cylinder housing 16 of which a plunger 17 is seated, which has a limited stroke path 18 of relatively short length.
  • the plunger 17 is designed as a relatively large-volume hollow piston and is in permanent communication with the pressure chamber 20 of the cylinder housing 16 via at least one passage 19 in the piston crown.
  • the pneumatic cylinder 15 has a considerable volume of air, which ensures an approximately constant spring rate over the maximum stroke path 18 of the plunger 17.
  • the plunger 17 of the pneumatic cylinder 15 is supported in its extended position, as can be seen in the drawing.
  • a double-acting hydraulic cylinder 22 is formed within the plunger 17 and a piston rod-like extension 21 adjoining it upward a line 26 can be connected to this pressure fluid supply source.
  • the differential piston 27 of the hydraulic cylinder 22 is fixedly connected to the piston rod 12.
  • the differential piston 27 By applying pressure fluid to the pressure chamber 23 of the hydraulic cylinder 22, the differential piston 27 is moved upward within the plunger piston 17 or its extension 21 and the piston rod 12 is thus moved upwards.
  • the pressure roller 2 and the deflection shell 3 are thus set against the circumference of the winding mandrel 1 via the four-bar linkage 5 and the roller and / or shell carrier 4.
  • the feed speed for the pressure fluid into the pressure chamber 23 the setting speed for the pressure roller 2 and the deflection shell 3 can be controlled as desired.
  • the contact pressure of the pressure roller 2 against the winding mandrel 1 can also be regulated.
  • Each set position of the differential piston 27 can be fixed in that hydraulic fluid is also present in the pressure chamber 25 of the hydraulic cylinder 22 and thus fixes the differential piston 27 in the respective position and dampens the movements of the piston rod 12.
  • This mode of operation is particularly important in the event that the pressure roller 2 and / or the deflection shell 3 is to be placed in a preposition during the winding phase of the coil before the end of the tape enters the underfloor reel, from which the remaining stroke for applying the pressure roller 2 or deflecting shell 3 is carried out against the circumference of the collar at a lower feed speed in order to limit the impact energy to the circumference of the belt collar to a minimum and to avoid damage to the belt.
  • the pressure chamber 23 of the hydraulic cylinder 22 is relieved of the pressure fluid and, on the other hand, pressure fluid is guided through the line 26 into the pressure chamber 25. This will make the differential piston 27 pushed downward, so that the four-bar linkage 5 of the roller and shell carrier 4 with the pressure roller '2 and the deflection shell 3 moves away from the winding mandrel 1 via the piston rod 12.
