Definitions

  • the present invention refers to a platen-press having a movable platen which is driven by toggle levers and which has a convex active surface which is brought into contact by a rolling motion against a fixed platen having a fiat surface.
  • FIG. 1 is an elevation view in section of a press
  • FIGS. 2-5 schematically show for the press various positions of the movable platen relative to the fixed platen
  • FIG. 6 is a sectional view taken along the line VIVI in FIG. 7, and
  • FIG. 7 is a sectional view taken along the line VII- VII in FIG. 6.
  • FIG. 1 there is shown a press whereln frame 1 1s integral with the fixed upper platen 24, againstwh ch the lower movable platen 23, the active face of which is convex, is applied by a rolling motion.
  • the driving of shaft is effected through a wormscrew 9 and a worm-screw 10, supported on the driving shaft 11 having a fly-wheel 12, the drive motor not being represented.
  • a solution to the drive of the lower platen is provided making use of simple means, easy to obtain with accuracy.
  • the toggle levers On the main driving shaft of the toggle levers, performing one revolution per working cycle there is arranged at least one cam imparting a swaying motion to a lever pivoted directly beneath the active face of the movable platen and being continued above of this pivoting point to engage the movable platen to enable the platen to slide and pivot at the same time in relation to thelever, the tying point of the connecting rods joining the main 3,182,588 Patented May 11, 1%65 shaft to the jointing centers of the toggle levers being distant from each other by an are less than 180.
  • FIGS. 2 to 5 correspond to the initial, middle end and lowered position of the movable platen with respect to the fixed platen, that is to the complete working cycle.
  • Opposite connecting rods 17, 18 are linked to the shaft 15 by joints 19 and 20 respectively and operate the median joints of the respective toggle levers 21 and 22, which are connected to the movable platen 23.
  • the platen 23 has a convex surface for cooperating with the plane lower face of the fixed platen 24.
  • the lever extends and its upper free end leads to a block 28 forming a guiding shoe in a slide 29 extending symmetrically with respect to the con vex face.
  • the block or shoe 28 can slide in the platen 23 in a direction substantially normally to the surface of the platen 23 while undergoing pivotal movement with respect to the upper end of lever 26.
  • the movable platen is constrained to perform a perfect rolling motion without sliding against the platen 24 in the manner as shown.
  • the joints 19 and 20 will pass at a lower symmetrical position as shown in FIG. 5.
  • the joint 19 is then to the right and the joint 20 to the left.
  • the centers of the two toggle levers will occupy their nearest positions to each other (the farthest are realized in FIG. 3) and the two ends of the platen 23 will be simultaneously lowered so as to provide a gap between the two platens, said gap permitting the transport between the platens of the pieces already processed and those to be processed.
  • FIGS. 6 and 7 show in detail an embodiment of the movable platen guiding means which has been described with respect to schematic representation.
  • a rectilinear groove 31 is provided, constituting slide 29 and in which is slidably supported shoe 28.
  • 33 represents a tool which is applied to the face of platen 23.
  • This latter platen 23 is driven in the manner already described in FIGS. 2-5 by toggle levers.
  • the shaft 15 supports the cam 16 and operates the lever 26 pivotally connected at 37 to the shoe 28.
  • the lever 26 is rotatably supported on axle 27 which is secured to element 39 of the frame. Screws (not shown) extending along axes 40 secure axle 27 to element 39 at the head 41 of the axle 27.
  • a similar head 42 and screws (not shown) and extending along axes 42, 43 secure pivot 37 in position at the end of the lever 26.
  • a spring 44 urges the roller 45 of the driven end of the lever 26 against the cam 16.
  • a platen press comprising a fixed platen, a movable platen having a convex surface and opposite ends, toggle levers connected to said movable platen, a drive shaft adapted for rotation, a pair of connecting rods connected to the drive shaft and to the toggle levers to cause the toggle levers to alternately lift one end of the movable platen and then the other end of the movable platen as the drive shaft undergoes rotation, a cam supported on said drive shaft, a lever having opposite ends and secured for pivotal movement intermediate said ends about a fixed axis, one of said ends of said lever being in contact with said cam to follow the motion thereof as the drive shaft undergoes rotation, and means connecting the opposite end of the lever to the movable platten for pivotal movement and for sliding motion in a direction normal to the surface of the movable platen to constrain the movable platen to undergo a swaying movement concurrent with the raising and lowering of the ends thereof to cause the surface of the movable platen to roll without sliding on the fixed plate
  • a platen press as claimed in claim 1 wherein said means connecting the opposite end of the lever to the movable platen includes a shoe, a slideway extending along a line which divides the convex surface symmetrically, said shoe being supported in said slideway for sliding movement and means pivotally connecting said opposite end of the lever with the shoe.
