Definitions

  • At least one wall portion is movable with respect to a fill box for precompression of scrap supplied thereto adjoining a cutter.
  • Vertical pivot means journal the wall portions at a location transverse to direction of scrap supply.
  • Fluid ac tuator means move at least one wall portion to swing about the axis of the pivot means.
  • Fluid actuator means are also provided at each of opposite ends of at least one wall portion movable with respect to an opposite wall portion. Only a partial cover transverse to the wall portions is provided for facilitating supply of scrap between the wall portions of the till box.
  • HELLMUT GALTER PATENTEU 0m 5 IHYI sum 2 OF 2 INVIZN'I'ORv HELLMUT GALTER SCRAP CUTTER This invention relates to a scrap cutter with precompression of the introduced scrap through a fill box with movable sidewalls.
  • Most hydraulically operable large scrap cutters are provided with cutting force of many hundred tons generally of the type having a'fill boxfor the scrap with building elements for precompression of the loose scrap filled therein. So it is known to provide movable sidewalls or side pushers which exert unifonn movement over the entire length of the fill box in a direction normal to the feed movement of the scrap.
  • Other solutions provide a folding box exerting folding movement likewise simultaneously over the entire length of the fill box and compressing the scrap. By these means the introduction of scrap is to be facilitated under a press or ram in the acl tual knife-guiding frame.
  • This precompression procedure is one event of the working sequence for each single filling of the box.
  • the working sequence accordingly is as follows: Filling the scrap, precompression procedure and finally stepwise feeding of the prepressed scrap extrusion to the knife by means of a be replenished and likewise scrap cannot be refilled into the box while the prepressing occurs.
  • The, collective scrap material must be supplied at one time during the filling procedure a and precludes the feeding of the cutter with continuously 3 operating conveyor means such as carrier belts, shaking conveyors and so forth. Fill materials of many 'tons' weight must be kept available by correspondingly applicable crane apparatus at exact filling time points. The simultaneous supply of collective fill materials also results in strong noise and dust'trouble. 6'
  • An object of the invention is to eliminate these disadvantages and to provide a scrap cutter with which the power input is kept small for precompression of supplied scrap and also that the total weight of the scrap cutter compared to known embodiments is minimized.
  • This purpose is inventively met by having at least one sidewall or one part thereof swingable at least about one of the two ends of the sidewall provided with joints having pivotal axis normal against the other sidewall, whereby swinging results by means of a hydraulic cylinder device.
  • a further development of the invention lies therein that the two sidewalls or movable parts of the sidewalls are swingable independently of each other about pivots offset with respect to each other at permanent locations with normal pivot axis.
  • both sidewalls or the movable parts of the sidewalls are secured to the cutter side end of the fill box by means of links with normal pivot axes the positions of which are adjustable transverse to the feed direction independently of each other with hydraulic cylinders.
  • the movable sidewalls of the fill box are provided above the stationary sidewalls of the fill box and liewith their lower edge movable adjacent to table surfaces and laterally on the upper edge of the stationary sidewalls.
  • FIG. 1 is a plan view upon a scrap cutter with a pivotable sidewall
  • FIG. 2 is a plan view upon a scrap cutter with two pivotable sidewalls and positioned across from fixed location of turning links;
  • FIG. 3 is a plan view upon a scrap cutter with turning links adjustable transverse to the feed direction
  • FIG. 4 is a section taken along line lV-lV in FIG. 3.
  • the precompression forces for pressing together the scrap supplied into the scrap cutter is kept within reasonable bounds so that the entire scrap cutter does not become too heavy.
  • the purpose of the invention is achieved by a step-formed feed pusher that works together with a swingably provided sidewall of the fill box.
  • the sidewall 4 of the fill box is pivotally joumaled by means of a fixed pivot joint 13 on the cutter side end of the fill box.
  • a hydraulic cylinder actuator 9 engages the pivot joint 14 of the sidewall 4 and swings the sidewall 4 in a direction toward the stationary sidewall l.
  • the feed of the scrap occurs in this sample embodiment by means of a step-formed pusher 3, which is guided on the stationary sidewall l and which is actuated by the hydraulic cylinder means 8 with a back-and-forth movement having a short stroke.
  • the fixed sidewall 1 of the fill box 2 forms an acute angle with respect to the feed direction of the scrap.
  • the fixed sidewall 1 guides and supports the stepped pusher 3 which carries out a short-stroke forward and rearward movement.
  • the sidewall 4 adapted for swing movement presses the supplied scrap against the step-type shoulders of the pusher It is notable that the scrap on its way over the length of the fill box also encounters difi'ering cross sections and is forced to occupy the same.
  • the scrap finally is pushed forward by means of 5 the pusher 3 and is repeatedly pressed with changing engagement points of the swingable sidewall 4 until the scrap comes to the stamper 5 and cutters 6, which are provided conventionally in the cutter guide frame 7.
  • a hydraulic cylinder means 8 moves the stepped pusher 3 and a further hydraulic cylinder means 9 moves the swingable sidewall 4.
  • the fill box can-have a partial cover 10 although a sufficiently longer part of the box is open at the "top-to permit continuous replenishment of new scrap.
  • the backwall of the fill box also can be adapted as a funnel-formed configuration.
  • the sidewalls 4a, 4b are pivotally joumaled with joints 13a, 13b having displaced positioning with respect to each other.
  • the hydraulic cylinders 9a, 9b engage the joints 14a, 14b of the sidewalls 4a, 4b.
  • a known feed pusher 11 serves for forwarding the precompressed scrap.
  • the swingable sidewalls 4a, 4b of the fill box 2 serve as pressure jaws whereby each sidewall is forced by the hydraulic cylinder means 9a, 9b in the direction toward the oppositely located sidewall.
  • the pivot points or joints 13a, 13b, 14a, 14b about which the sidewalls swing have offset positioning with respect to each other.
  • the feed pusher 11 functions only when the two press jaws or sidewalls are moved from their operating position into their starting posijusted by means of hydraulic cylinder devices 16 and 16 transversely with respect to the feed direction.
  • the cylirider devices 9A, 16 and 9B, 16 the movable walls 4A and' lBcan be moved in acute angles and also parallel to the feed direction independently of each other.
  • FIG. 4 represents the cross section taken at line lV-IV in FIG. 3.
  • table surfaces 17 and 17' connected therewith, upon which the movable sidewalls 4A and 4B are 5 movably supported with their lower edges.
  • a channel 12 located in the knife cutting plane and into which the precompressed scrap arrives after opening or separation of the two pressure jaws or walls.
  • the precompressed scrap located in the channel 12 also is transferred by means of the feed pusher 11A to the stamper or ram 5A and cutter means 6A of frame 7A.
  • a scrap precompression apparatus adapted to be used adjacent a scrap cutter including a fill box supplied with scrap for precompression, said precompression apparatus comprising: at least a pair of sidewall portions between which scrap is received in the fill box and having opposite ends spaced from each other, pivot means defining a turning axis and joumaling the end of at least one sidewall portion to swing with respect to the other sidewall portion of the fill box, and fluid actuator in which more than one pivot means offset with respect to each other in permanent locations are provided for said sidewall portions to swing independently of each other.
  • a scrap precompression apparatus in which both sidewall portions at ends thereof have said pivot means, and separate fluid actuator means provide independent adjustment of said sidewall portions.
  • a scrap precompression apparatus in which the fill box also has fixed sidewall portions with top edges and defining table surfaces, said pair of sidewall portions both being movable above said fixed sidewall portions of the fill box, and a bottom edge of said sidewall portions movably engages said top edges of said fixed wall portions adjoining said table surfaces.
  • a scrap precompression apparatus in which fluid cylinder means are provided at each end of said one sidewall portion and a partial cover adjoining the cutter end thereof is transverse to said sidewall portions between which scrap is supplied.
