Definitions

  • Crushing is basically the deformation of space consuming or loose material by squeezing it into compact shapes of a substantially smaller volume than that taken up by the pre-crushed material. Crushing is usually performed to render bulky lots of scrap material easily storable and to facilitate their disposal or reuse. The greater proportion of commercial crushing occurs in the preparation of scrap metal for reuse in steel making and a great portion of this scrap is comprised of junked automobiles and automobile parts.
  • the equipment used in crushing is essentially a power press which has its ram connected to move one sidewall of a closed rectangular box towards an opposite stationary sidewall to thereby squeeze the material contained in the box to a predetermined compact size.
  • the above mentioned box is usually' referred to as the squeeze box and the sidewalls are referred to as the movable and stationary platens.
  • the material may be either bailed, sheared into smaller pieces, or utilized in the as-crushed state.
  • the scrap is crushed to a compact column approximately 15 to 22 feet in length and 2 to 3 feet square in cross section. Such columns have to be cut to several smaller sections before the crushed scrap may be utilized in the steel making process.
  • These pieces will be loaded in such compression if, at the time when they are subjected to the compressive force of the press, they are in axial alignment with the travel of the movable platen and are engaged at their opposite ends by the parallel working surfaces of the platens.
  • the resistance offered by the axial compression loading of these pieces can be designated as column resistance. In cases where column resistance occurs the press has to exceed the force necessary to buckle any of such pieces in order to overcome the column resistance and to enable the charge to be compressed to the desired size.
  • the operator retracted the movable platen, repositioned the frame, and again advanced the movable platen with the hope that the new position of the frame would offer less column resistance than in the first instance.
  • crushing of automotive frames was considered to be a hit and miss operation.
  • the compacted pieces often were wider than desirable because the fold present in the buckled cross member would not permit compression beyond a given point.
  • Some problems in cutting the compacted piece were also present. If the buckled section happened to be at the intended cut line, a substantial portion of the cross member would lie on the cut line and transversely to the mouth of the shear and therefore hinder or even prevent cutting at the desired location.
  • the principal object of this invention is to improve the scrap crushing apparatus by substantially reducing the effects of the column like scrap pieces upon the crushing operation.
  • a further important object of this invention is to improve the apparatus for processing automotive scrap by eliminating the effect of the automotive frame cross members upon the crushing and cutting operations of this process.
  • This object is attained by providing a movable platen which is moved towards a stationary platen in a path oblique to the working surfaces of the platens. Because of this direction of motion, any force which will be exerted on a piece positioned between the plat-ens will necessarily have a compressive as well as a turning or moment component and therefore will cause the piece to rotate out of axially aligned position before it can offer any substantial column resistance to the platen movement. By maintaining the platen and the opposite wall parallel to each other, the crushed material will still be of substantially uniform outer contour which is necessary or desirable in many cases yet the uniformity in the consistency of the crushed material will be substantially improved.
  • the oblique platen movement is of particular significance in processing automotive scrap since the automotive frame will collapse or fold in response to the compressive and moment forces exerted by the movable platen. Essentially, the opposite side bars of the frame will be each engaged by one of the platens and will be moved towards each other as well as in opposite directions parallel to each other, thereby causing the cross members to be turned to a generally longitudinal position within the squeeze box without offering any column resistance.
  • the present invention changes the hit and miss type of operation to a predictable and reliable process.
  • Another important advantage is gained by the fact that the side bars of the frame are turned to a longitudinally aligned position in respect to the compacted scrap piece. Because of this, they will be always transversely positioned in respect to the out line of the shearing press and therefore will permit easy cutting at any desired location.
  • FIG. 1 is a top plan view of the crusher embodying the present invention with the crusher cover being open to illustrate the uncrushed charge and with the movable platen being in a retracted position;
  • FIG. 2 is a top plan view of the crusher shown in FIG. 1 with the movable platen being at the end of its power stroke and with part of the cover being broken away to show the deformation of the charge;
  • FIG. 3 is a cross-sectional side view taken on line 3-3 of FIG. 2;
  • FIG. 4 is a cross-sectional end view taken on line 44 of FIG. 3 with the movable platen being shown by broken lines in its retracted position and with the cover being shown in broken lines in its open position;
  • FIG. 5 is a view taken on line 55 of FIG. 3.
  • FIGURES 1 and 2 show the condition of the charge in its uncompressed and in its compressed state respectively.
  • the charge has been placed in the squeeze box 12 when the squeeze box is at its maximum volume as, shown in FIG. 1.
  • the charge is shown to include a column like piece of scrap 14, such as an I-bearn or a channel, which is positioned with its axis perpendicularto the parallel working surfaces 16 and 18 of the movable platen 2t and the stationary platen 22 respec tively.
  • a rectangular box section 24 which is representative of an automotive frame is shown centrally positioned in the squeeze box with its sides 26 being analogous to the cross members of the frame and being positioned perpendicular to the two working surfaces of the platens.
  • the other sides 27 of the box are representative of side bars of the frame and are longitudinally disposed in respect to the squeeze box.
  • the other pieces of scrap are shown to be randomly distributed throughout the box with their axes lying at various oblique angles to the working surfaces.
  • the squeeze box itself is of relatively simple construction. In its open position it is of a rectangular shape having a base platform 28 which rigidly supports the stationary platen 22 and'having a cover 30 pivotally connected to the upper edge of the platen by pins 32. The cover may be moved between the open and closed position by pressure responsive cylinders 34 which are connected to the lever arms 36 of the cover in the customary manner.
  • the movable platen of course forms the other side of the squeeze box.
  • the platen has a cross sectionally channel shaped contour to provide horizontally extending top and bottom flanges 38 and 40. The flanges 38 and 40 are in slidable engagement with the base platform and cover respectively.
  • the side faces 42 of the platen 20 are in similar slidable engagement with the guide faces 44 of the guide blocks 46 which are fixed to the base platform.
  • Two pressure responsive cylinders 50 are connected to the platen and to a source of mechanical power for moving the platen 20 between the positions shown in FIGURES l and 2.
  • the guide faces 44, the sides 42 of the platen, and the cylinders 50 extend in the horizontal plane at an angle oblique to the working surfaces 16 and 18 of the platens.
  • the hydraulic cylinders 34 are actuated to close the cover.
  • the hydraulic cylinders 50 are actuated to advance the movable platen 20 from its retracted position towards the stationary platen 22 along the oblique path defined by the guide faces 44. Because of the oblique path the motion of the platen 20 has a substantial component towards and perpendicular to the working surface 18 of the stationary platen and also a component of motion parallel to the working surfaces and towards the right when viewed in FIGURE 1.
  • the force exerted on the charge of course also has two components identical to those of the platen motion.
  • the movable platen is moved back by cylinders 50 to its retracted position, the cover is opened, and the ram 56 is actuated from a source of power (not shown) to advance the crushed charge towards the shear press which is positioned immediately adjacent one end of the squeeze box.
  • the shear press is provided with a ram 56 which carries a cutting tool 58 and with a corresponding cutting tool 60 mounted in its frame. The actuation of the ram 56 can be coordinated with the operation of the press to cut the crushed charge into pieces of any desired length.
  • An apparatus for compressing scrap metal comprismg:
  • a squeeze box having a base platform, a stationary platen forming one side of the squeeze box and a movable platen forming the other side of the squeeze box, said movable platen being movable between a distant position in respect to said stationary platen and a close position in respect thereto so that uncrushed scrap material can be positioned on said base platform when said movable platen is in said distant position and crushed upon movement of said movable platen towards said close position;
  • An apparatus including shearing means positioned at one end of said squeeze box so that the compressed material can be advanced along said base plaform towards said shearing means to be cut thereby; and the shearing means having a cutting line generally transverse to the end-to-end axis of said squeeze :box.
