Definitions

  • ABSTRACT 52 US. Cl ..214/1 QD, 18/16 R, 18/34 R, A device for finishing complementary die or mold parts and 72/448, 72/470, loo/DIG. 18 similar complementary parts has a base plate for supporting a [51] Int. Cl.
  • the invention relates to a device for finishing die or mold parts and other complementary parts, and more particularly, to a device of this kind in which one part to be finished such as the top part is supported by a support member which is linearly movable toward and away from a second support member supporting thereon the second part to be finished such as the bottom part, the first support member being also swingable from an operating position into a position for finishin g the part supported on said member.
  • finishing is intended to refer to correcting irregularities or flaws as may interfere with the operation and use of the complementary parts.
  • BACKGROUND Devices of the general kind above referred to as now known are generally so arranged that the first support member is suspended at an angle of about 90 relative to the second support member when the first support member is fully swung out as much as possible.
  • the part supported by the first support member is then hanging just outside of the device, and as a result at least some portions of this part are not or at least not conveniently accessible for finishing.
  • Convenient accessibility of the swung out suspended part is particularly important when the device such as a press is designed for finishing large parts. In such case, the operator may have to step upon an elevated platform as otherwise he would not be able to reach all positions of the part.
  • a more specific object of the invention is to provide a novel and improved finishing device or press which permits placement of the lower part in a position in which both parts are accessible with equal ease.
  • the device or press of the invention also provides for lowering of the upper part into complementary or coacting position with the lower part for checking whether the two parts are fully satisfactory, or whether further finishing work is necessary.
  • a support plate mounting this part can be swung out of the device or press by an angle of more than 90.
  • a pivotal movement through about 140 is sufficient, but it is sometimes preferable to provide for a pivotal movement through 180 to bring the two parts into planar alignment.
  • Guide and support means for guiding the swingable support plate while being pivoted out of the device or press are preferably provided.
  • FIG. 1 is a diagrammatic elevational view of a finishing device or press showing the two parts to be finished in positions for movement into coaction with each other;
  • FIG. 2 is a similar elevational view of the device or press showing the lower part to be finished in a laterally displaced position and the support plate for the upper part swung out of the device or press by an angle of more than 90";
  • FIG. 3 is an elevational view similar to FIG. 2, but showing the support plate and the upper part thereon moved out of the device or press by an additional angle;
  • FIG. 4 is an elevational view similar to FIG. 3, but showing the support plate and the upper part thereon in a position swung out by an angle of 180, so that the two parts are substantially coplanar disposed, both facing upwardly;
  • FIG. 5 is an elevational diagrammatic view of a device or press with a modified drive means for pivoting and guiding the support plate supporting the upper part to be finished;
  • FIG. 6 is an elevational diagrammatic view of a finishing device or press in which the guide and drive means for the pivotal support plate are further modified;
  • FIG. 7 is a diagrammatic elevational view of a modification of the means for supporting the pivotal support plate for the upper part to be finished.
  • the exemplified finishing device or press as shown in FIGS. 1 to 4 comprises a crossbar or head 1 fixedly mounted on guide members such as v uprights or columns la.
  • the columns support displaceably thereon a slidable member or ram 2, the bottom side of which has hinged thereto by means of a hinge 4 a support plate 3.
  • Member 2 and plate 3 are up and down movable from the uppermost position of FIG. 1 into the lowermost position of FIG. 4.
  • the device is shown vertically arranged. Such arrangement is often the preferred one, but it should be understood that it is also within the concept of the invention to arrange members la in horizontal position in which case member 2 and plate 3 are horizontally displaceable.
  • Pivotal plate 3 is held in the horizontal position of FIG. 1 by a drive means 5 which when operated effects the pivotal movements of the plate into the positions shown in FIGS. 2 to 4, and more fully described hereinafter.
  • the base part of the device or press comprises a carriage or sled 6 which can be laterally displaced on a base member 7 such as a table from the position of FIG. 1 into the position of FIG. 2.
  • Carriage 6 supports a part 8 to be finished. This part may be visualized as the lower half of a die or mold facing upwardly. A complementary upper part 9 of the die or mold is suitably mounted facing downwardly on support plate 3.
  • Slidable member 2 and plate 3 are lowered into the position in which the parts 8 and 9 engage with each other.
  • a check can then be readily made whether the two parts have the required complementary shape -for instance, two mold parts should engage with each other without gaps or openings therebetween.
  • Checking of the two parts can be effected by injecting between the parts a suitable medium, for instance, by means of a conventional pressurized spray device, as is diagrammatically indicated at 30.
  • the check medium is selected in accordance with the type of work involved; generally, it should be a medium which can be injected at low temperature between the two parts and is harmless so that working men nearby are not injured if the two parts are not tight and part of the check medium is blown out or leaks out.
  • a device as hereinbefore referred to may be a heavy press or ram weighing several tons so that the forces to be controlled are very considerable.
  • the two parts 8 and 9 may be die parts for shaping metal or other material between the two parts when the slidable member 2 is lowered in the manner of a ram against an anvil, coacting with carriage 6 and table 7 acting as anvil.
  • a drive for moving the slidable member 2 up and down and a drive 5 for pivoting support plate 3 may be visualized as hydraulic drives, but of course other suitable drives can also be used.
  • FIG. 1 shows the device or press in a position in which parts 8 and 9, which may be visualized as having been finished, are ready for coaction with each other.
  • FIG. 2 shows the hydraulic drive 5 operated for pivoting plate 3 from the position of FIG. 1 into the position of FIG. 2.
  • Such pivoting of the plate is effected by means of a connecting rod 13 linked by a pin 14 to one end of plate 3, the other end of which is linked to slidable member 2 by hinge 4 as previously described.
  • the drive 5 itself, or more specifically, its cylinder 50, is guided and supported by a rest 16 on a bracket 15 extending from crossbar 1.
  • pivoting of plate 3 through an angle of more than 90 swings the plate clear out of the way ofcolumns la.
  • FIG. 2 also shows that the carriage 6 is laterally displaced into a position spaced apart from the columns. Displacement of the carriage which is supported on rollers or wheels 6a can be effected manually or preferably, by a drive means shown as a motor 35 releasably coupled to an axle of wheels or rollers 60, as it is diagrammatically indicated in FIG. 1.
  • the carriage is preferably displaced prior to the pivoting of plate 3.
  • FIG. 4 shows the lower end position of plate 3 in which the same rests on guide tracks 12 in a position substantially coplanar with carriage 6.
  • the mold or die part 9 is now positioned facing upwardly and is freely accessible, as is mold or die part 8.
  • FIG. 4 also shows that cylinder 5a is now in an approximately vertical position so that it does not interfere with working on mold or die part 8.
  • Part 8 together with its carriage, may be lifted if necessary by suitable hoist means.
  • a hoist motor 40 secured by a bracket 41 to table 7.
  • a frame 42 serves to support hoist ropes 43 and 44 guided over suitable pulleys 45 and detachably secured to carriage 6, as it is indicated at 46.
  • the hydraulic drive means 5 and more specifically, the cylinder 5a thereof, is hinged to about the middle of sliding member or ram 2. As this member is lowered, the cylinder is guided by an abutment surface 17 on crossbar l.
  • the figure shows the working position of the device or press in full lines, the movable parts being shown in an intermediate position (corresponding to FIG. 2) by dashed-dotted lines, and in the end position (corresponding to FIG. 4) by dashed lines.
  • cylinder 5a' of hydraulic drive means 5 is guided by a rope or chain 18 attached at one end to sliding member or ram 2 and at the other end to cylinder 5a.
  • An intermediate point of the rope is guided over a pulley 19 on crossbar 1.
  • the plate is supported and guided by guide 12 pivoted to table 7, as already mentioned.
  • the guide can also be mounted separate from the device or press either on the floor or on a separate platform.
  • pivoting of support plate 3 is again effected by means of hydraulic drive means 5 and the connecting rod 13 which is linked at one end to plate 3 by pin 14.
  • the same end of the plate also mounts rolls or coasters 11.
  • FIG. 7 shows an arrangement in which pin 14 is held in a claw 20 on the end of rod 13.
  • the claw is open on its side facing support plate 3 and formed with a guide surface 21, the purpose of which will be more fully explained hereinafter.
  • Guide 12 extending from table 7 mounts a curved guide surface 23.
  • the figure shows support plate 3 and claw 20 in three different operational positions designated by A, B and C.
  • the sliding member or ram 2 is preferably lowered by means of its drive (drive 10) in the direction of arrow 22, so that the support plate 3 eventually reaches the position in which its roller 11 rests on curved surface 23. Further lowering of member or ram 2 now moves plate 3 into the position C and finally into its lower horizontal position (see FIG. 4).
  • Pin 14 is freed of claw 20 as the rod 13 and thus the claw participate in the movement of sliding member or ram 2 while pin 14 continues its relative movement in the direction of the pivoting of plate 3.
  • the control of drives 5 and 10 of the press or device is preferably so arranged that the aforedescribed sequence of movements of the plate while being pivoted and also reaching either end position is assured and occurs automatically in both directions.
  • the entire press or device may be arranged in horizontal position, that is, in a position in which the members la are horizontal while the crossbar 1, the sliding member or ram 2 and the table 7 are vertical.
  • a device for finishing complementary mold parts, die parts and other complementary parts comprising in combination:
  • a base member for supporting a first part to be finished
  • guide members slidably guiding said slidable member for linearly displacing the same relative to the base member
  • a support plate for supporting thereon a second part to be hinge means hinging the support plate to the slidable member, said support plate being pivotal between a position substantially parallel to the slidable member and an angular position more than 90 out of said parallel position;
  • a guide means extending from said base member substantially planar therewith, said guide means constituting a support and a guide for the support plate as the same is being pivoted relative to the slidable member.
  • the device according to claim 1 and comprising a first drive means including a connecting rod, and hinge means linking said connecting rod to said pivotal support plate, and a second drive means drivingly coupled to said slidable member at about the middle thereof for displacing said member, said first drive means being supported by said slidable member.
  • a crossbar extends across said guide members attached thereto at a fixed distance from said base member, and guide means on said crossbar to guide said first drive means for controlling the angular position of the first drive means during displacement of the slidable member by the second drive means.
  • said guide means comprises a rope secured at one end to said slidable member and at the other end to said first drive means, said rope being guided at an intermediate point by a guide means on said crossbar.
  • a drive means is releasably coupled to the support plate by coupling means for pivoting the support plate, said coupling means including an open claw supported by the drive means and a pin on the plate, said pin sliding out of the claw in a predetermined pivotal position of the support plate but remaining engaged therewith in all other pivotal positions of the plate.
