Definitions

  • the invention relates to a closure element for a machine frame of a roller press, which is seated at the end as a cover on a frame element.
  • the forces that occur in the machine frame, which holds the two counter-rotating rollers together, are very high. Accordingly, efforts are made to design the machine frame to be appropriately stable.
  • the high-pressure roller press quickly gains in weight thanks to the stable machine frame.
  • the handling of the individual parts of the frame of the high pressure roller press and the transport of the roller press are made more difficult. There are high costs involved in transporting the machine parts to the area where the roller press is to be used, with the areas where the press is to be used are often less developed and far removed from the infrastructure.
  • the European patent application EP 1 374 999 A2 discloses two bridge elements comprising two roller bearings and encompassing two vertical struts like a bracket. It also discloses a machine frame according to the preamble of claim 1.
  • the French patent FR 2 216 105 discloses a four-part removable frame in which two vertical struts and two bridge elements form a four-part frame.
  • the vertical struts can be angled in order to detach the roller bearings arranged between the bridge elements. This Rahman also does not adapt to the dynamic changes in load during operation.
  • German Offenlegungsschrift DE 10 2005 045 273 A1 discloses a machine frame having tuning fork shaped frame members.
  • the machine frame is closed by pivoting frame parts that are firmly closed with the tuning fork-shaped frame during operation.
  • the European patent application EP 1 147 815 A2 discloses a two roll machine with swing arms.
  • the vertical struts can be angled in order to detach the roller bearings arranged between the bridge elements.
  • the swivel arms have no device for adapting to a dynamic load change.
  • a machine frame in the form of a tuning fork which absorbs a self-contained system of forces consisting of roller presses and pressure hydraulics.
  • This machine frame is closed on each side of the machine frame with an open frame section as a lock, which is thrown over the legs of the tuning fork-shaped machine frame, this frame section sitting as a lock in a bay of the legs of the tuning fork-shaped machine frame and against the hammer-head-shaped one that forms a bay Widenings in the legs of the tuning fork-shaped machine frame.
  • This frame section as a closure is itself constructed in a U-shape and rests on the upper leg of a machine frame side of the tuning fork-shaped machine frame and can absorb high, horizontally directed forces of the rollers, whereby the forces of the rollers are transmitted via stub shafts that sit in a bearing block via the bearing block to the frame section as a closure.
  • This construction it is important that the high lateral forces that can occur in the machine frame are evenly transmitted to the legs of the tuning fork-shaped machine frame. Without special precautions, it can happen that the frame section becomes wedged as a lock in the bay of the leg of the tuning fork-shaped machine frame and can therefore only be released from the tuning fork-shaped machine frame during the next disassembly under difficult conditions.
  • the object of the invention is therefore to provide a machine frame for a roller press with a lock that does not become wedged.
  • the object according to the invention is achieved by the machine frame with the lock having the features of claim 1.
  • the closure element also perform a pendulum movement during use.
  • the closure element is therefore not permanently connected to the frame, but provision is made for the closure element to be mounted in a floating manner.
  • floating mounting is understood to mean that the closure element has more than one degree of freedom of movement in use. It can therefore move in more than one degree of freedom in the machine frame. This ensures that the closure element aligns itself under load in such a way that it does not become wedged, but rather clings to the corresponding abutment with all contact surfaces and thus absorbs the maximum design-related force can without the locking element becoming wedged due to undesired placement on the machine frame and thus undesirably tightening there.
  • a machine frame 10 is shown in patent application DE102010015374.5 is described in detail and have two tuning fork-shaped frame elements 11 and 12 as an essential element, which are open to the rear in this illustration.
  • tuning fork-shaped frame elements 11 and 12 are approximately rectangular frames, which give the entire machine frame 10 the necessary torsional stability.
  • two locking elements 21 and 22 are placed onto the tuning fork-shaped frame elements 11 and 12 from above.
  • These closure elements have a U-shape and each of their legs encompasses one leg of the tuning fork-shaped frame end component.
  • the locking elements 21 and 22 engage in bays of the tuning fork-shaped frame elements 11 and 12 and are braced against hammer-head-shaped end pieces 23 and 24 of the tuning fork-shaped frame elements 11 when the roller bearings located inside the tuning fork-shaped frame elements 11 are loaded horizontally. According to the invention it is provided that this Closure elements 21 and 22 are not firmly connected to the tuning fork-shaped frame elements 11, but are floatingly mounted on them.
  • the swimming is achieved in each case by a displaceable bearing 30 which is arranged on the inner side of the connecting piece of the two legs of the U-shaped closure elements 21 and 22 and which there has a ball head joint 31, which in Figure 3 and has a slide plate 32 also shown in FIG Figure 3 is shown.
  • a displaceable bearing 30 which is arranged on the inner side of the connecting piece of the two legs of the U-shaped closure elements 21 and 22 and which there has a ball head joint 31, which in Figure 3 and has a slide plate 32 also shown in FIG Figure 3 is shown.
  • the closure elements 21 and 22 can take almost any position at the moment in which it leans against the hammer head-shaped ends of the tuning fork-shaped frame elements 11 and fall into the position defined by the contact points of the hammer head-shaped end pieces 13 and 14 of Tuning fork-shaped frame elements 11 are given.
  • the floating closure elements 21 and 22 allow on the one hand a quick opening of the tuning fork-shaped frame elements 11 and 12 to change the rollers contained therein, which have to be replaced or refurbished after a predetermined time due to wear, on the other hand the fast-opening closure elements 21 and 22 allow a constant optimal contact with the hammer head-shaped end pieces of the tuning fork-shaped frame elements 11 and 12, which serve as abutments.
  • the securing bolts 40 can each have a split pin, by means of which the securing bolts 40 are secured in the closure element 21 and 22, or they can each have a thread with which the securing bolts 40 is secured in the closure elements 21 and 22.
  • the locking bolts 40 have a larger diameter, than the respective threaded head, not shown here.
