Definitions
- the invention relates to a method and an apparatus for removing residual press and shell of a press disk or die according to the preamble of the claims 1 and 2 (see e.g. EP-A-0 224 115).
- the press disk or die is on End of the pressing process from one end of the press disk or die remaining baling residue and a shell connected to the baling residue depending on the Working methods and the type of tool used in whole or in part surround, with the shell in an annular chamber on the outer edge of the press disk or matrix, or when the shell is pushed up in a special operation the end of the press disk or die opposite the press rest behind this collects.
- the Press residue and the shell are removed.
- the removal of the press residue and, if applicable, that behind the press disk or The shell that is upset is placed on the one that has the press residue on it Front side of the press disk or die along the knife and if necessary one on the opposite side of the face, covered with the upturned shell second knife guided along.
- the first knife forms together with the second Knife or a guide plate a frame in which the knife or the knife and the guide plate a clear distance according to the axial dimension of the press disk or the die through which the press disk or die is moved parallel to their end faces, then the end faces occupying remnants (press remnant and swollen shell) or the one end face supporting press residue is sheared off.
- the shell section enclosing the outer circumference of the press disk or die or the shell that is upset in the ring chamber is replaced by a side in the frame arranged the notch knife or by two notch knives cut twice so that the bowl jams at the notch knife and from the Press disk or die is pressed (DE-AS 25 06 447, DE-OS 26 13 241).
- Knife knife Instead of fixed notch knives are attached to handlebars according to EP 0 224 115 A2 Knife knife known that the feed of the press disk or die at the Scrape the circumference and peel off the shell.
- the object of the invention is to remove the shell from the To achieve press disk or die with even greater certainty.
- This task is solved by radial expansion of the shell to be removed by means of Rolling pressure while rotating the residues on their end faces (press residue, upset shell) liberate the press disk or die and turn the counter this radially adjustable roller or rollers and by subsequently stripping the sufficiently widened shell.
- a device for practicing the method according to the invention are one two knives or a knife and a guide plate at a distance of the axial Dimension of the press plate or die holding frame and a frame Press disk or die parallel to their end faces along the knife or Knife moving slide existing press remainder according to another Feature of the invention with a central, rotatable receptacle for a Press disk or die and at least one radially against the press disk or Expandable rolling mill for adjustable Detach the shell from the press disk or die and means for separating and separate application of the pressure plate or die and the shell downstream.
- An advantageous design of the expanding mill provides three adjustable rolls. It is also advantageous that the receptacle for a press disk or die and the roller or rollers in a horizontal plane with vertical ones Axes of rotation are arranged.
- the shear part 1 is, for example, from DE-OS 25 05 160 or EP 0 224 115 B1 known manner and consists of a receiving table 3 on which the via a suitable transport system supplied by the extrusion press, with the Press rest and the shell-bearing press disks or dies 4 are placed.
- a piston-cylinder unit on one side 5 movable slide 6 and coaxially on the other side a frame 7 for one lower knife 8 and an upper knife 9 are provided.
- the stripping part 2 designed according to the invention as an expanding mill is in the exemplary embodiment provided with three rollers 12 which are rotatably mounted in chocks 13 and with this of piston-cylinder units 14 to move radially to the system axis are. At least one of the rollers 12, in the exemplary embodiment two are through driven a hydraulic motor 27.
- the rollers 12 with their chocks 13 leading roll stand 15 is made of an upper plate 16 and a lower plate 17 and roller guides 18 arranged between these and designed as spacers, Disc guides 19 and chamber walls 20 assembled.
- a support plate 21 can be rotated in from the bottom in the system axis used plate, not shown.
- a piston-cylinder unit 22 is provided, which for protection with a jacket tube 23 is surrounded, which is connected to the support plate 21 and telescopically an inner Includes support tube 24.
- the support plate 21 is provided with lateral flats, so that they are lowered by a fork-like scraper plate 25 can, whereby a press disc or die 4 'freed from the shell when Lowering is stripped and into a groove 26 for return transport to the extruder arrives.
- Pistons are guided in cylinders 28 in the middle of the angle between the rollers 12 as tappets arranged, each carrying a clearing plate 30, the contour of which is in its essential part is determined by the pressure plate or die and two adjacent rollers 12.
- each Broaching plate 30 is provided with two guide pins 31 which are in the bores 32 of the Upper plate 16 and the mounting flanges 33 of the cylinder 28 are guided.
- the top plate 16 and in FIG. 6 the bottom plate 17 shown.
- the disc end guides 19 and the chamber walls 20 with the 5 shows the top plate 16 with the bottom plate 16 and the bottom plate 17 central opening 37 through which the press disk or die observed from above, or how can be applied in a modified version upwards.
- 6 shows the lower plate 17 with its star-shaped opening 40 which is a central opening for the passage of the support plate 21 with the press plate or die 4, the openings 34 and the opening 35 for the Removal of the shell scrap summarized
- the two rollers 12 are on the side of the web the pressure plate or die 4 extended to a distance of at least that Diameter of the press disk or die 4 with the shell.
- the disk guides 19 are used for lateral guidance and to support the pressure plate or die 4 strips 33 serve on the disk guides 19, and on the last path support plate 21 is in its upper position.
- the three rollers 12 are concentric turned on, pressed against the press disk or die 4 and set in rotation
- This rolling process exerted on the shell causes the shell to widen, between the rolling zones to form a loop of the shell parts and their detachment from the circumference of the press disk or die leads.
- the ongoing Rolling and alternating bending stress on the shell usually leads to an early stress
- the shell and the fragments break through one of the openings 34 below the chambers enclosed by the chamber walls 20 or through the opening 35 between the guide strips 33 in a scrap bucket 36.
- the shell expanded by the rolling process can break are supported in that the rollers are provided with cutting edges by the the shell is notched transversely to the rolling direction, which is a defined end position of the Rolls presupposes, in order to damage (notch) the press disks or Exclude matrices.
- the collar diameter including the cutting edge height Basic diameter of the roller should not exceed the depth of the Annular chamber is so that when the roller comes into contact with the press disk or die the cutting edge has not yet reached the bottom of the ring chamber. In any case but the cutting edge height may be less than the shell thickness thus widening the Shell is sufficiently reached by the rolling.
