Wright, Silver Lake, Ohio (2994 Silver-lake BlvdL, Cuyahoga Falls, Ohio), and Walter Nagel, Silver Lake, Ohio (2923 Circle Drive, Cuyahoga Falls, Ohio); said Camplliiell alssignor of one-sixth each to said Wright and said age Filed July 19, 1961, Ser. No. 125,189 26 Claims. (Cl. 18-46) This invention relates to presses, and in particular relates to a die spotting or like press.
In the past, die spotting or like operations generally have been accomplished by mounting top and bottom mating sections of the die between vertically relatively movable press platens. Presses available for this purpose, however, require removal of the mating die sections from the press after each die-registering movement of the platens, as for mounting the die sections on a work bench for checking, grinding, or other corrective steps. Repeated removal and remounting of the die sections was tedious and time consuming, and accordingly uneconomical and otherwise unsatisfactory. Because certain inspection and grinding steps were required to be done at a point or points remote from the machine the effective space required for the entire operation was substantial.
One object of the present invention is to provide a die spotting or like press having improved means for relatively moving the die sections between mating relationship and a condition in which the die sections are presented at remote points to have the mating portions thereof conveniently exposed for further work thereon, all without necessitating removal of the die sections from the press.
Another object of the invention is to provide a press of the character described which is automatic for requisite cycles of operation and/or selectively operable through various individual movements of the die supporting means.
Anodier object of the invention is to provide a press of the character described which is readily adjustable to accommodate dies of various sizes, and wherein the platens are self-aligning to eliminate the usual necessity for dies thereon to have registering dowel pins.
Still another object of the invention is to provide a press of the character described having improved means for applying heavy force to urge the die sections into registering relationship, and likewise for applying reversely effective heavy force to urge the die sections apart, as when an article formed in the die tends to bind the die sections together.
A further object of the invention is to provide a press of the character described including vertically relatively movable die-supporting platens, and improved means for moving one of the platens to an inverted position at a point remote from the other platen, to facilitate checking or remedial work on die sections supported on the platens.
These and other objects of the invention will be manifest from the following brief description and the accompanying drawings.

General Description of the Press Referring generally to FIGURES 1 to 9, the numeral 15' designates an article-forming die, including mating top and bottom sections 16 and 17, adapted to be secured to relatively movable, top and bottom platens 18 and 19 respectively. Bottom platen I? is vertically movably supported on one end of an elongated supporting frame 20, between laterally spacedside rails 21, 21 thereof. Top platen 18 is releasably affixed on a platen support 22 vertically movably supported on an upright carriage 23, which is longitudinally, shiftably supported on the side rails 21. In other words, when the carriage 23 is vertically aligned with bottom platen 19, as shown at position B in FIGURE 1, the top platen 18 and its support 22 are vertically movable as a unit on the carriage, to fixed positions with respect to the bottom platen, and the bottom platen is also vertically movable toward and from the fixed top platen, as by means of a hydraulically operated toggle mechanism 25, to be described later. The arrangement is such that the top platen 18, carried by its support 22 on carriage 23, is movable through a ser1es of positions, with respect to the bottom platen 19, IIlCllldlI'lg full and chain-dotted positions A to H, indicated correspondingly in FIGURES 1 to 7.
The Carriage Referring particularly to FIGURES 1, 2 and 3, the carriage 23 includes opposite upright side members 26, 26 and a top cross-head 2'7, and is supported on frame 261 to move horizontally thereon, as by means of longitudinally spaced pairs of rollers 28, 28, on transverse extensions 29 of the side members, these rollers being adapted to roll on tracks 30 affixed on the upper edges of the frame side rails 21. Tilting action of the carriage on the frame is prevented by inturned portions 31, on downward extensions 32 of the carriage side members, engaging under longitudinal guide strips 33, 33 on said side rails 21.
For moving the carriage on the fixed frame 20, power means 35 is provided on the cross-head 27, the same including a reversible electric motor 36 which, through a gear reducer 3'7 and a chain drive 38, rotates a horizontal shaft 39 journalled on the cross-head. Gears 40 on shaft 39 in turn mesh with gears 41 on the upper ends of vertical shafts 42 journalled on the opposite side members 26, for rotating pinions 43 keyed on the lower ends of said shafts, so that meshing engagement of the pinions with racks 44 extending horizontally on the side rails 21 of the frame 2i will move the carriage along the tracks 30. Limit switches LS6 and LS3 are arranged at the left and right hand ends of the frame, as shown in FIG- URE 1, respectively to stop travel of the carriage in alignment with the lower platen 19, or in alignment with laterally spaced trunnion bearings 45, which are affixed on the frame 20, for purposes to be described later (see corresponding positions A and D in FIGURE 1). In these extreme positions of movement of the carriage, corresponding rollers 28 will be in engagement with stops 46, 46 at the respective ends of the frame rails or sides 21 The Top Platen Member Again referring particularly to FIGURES 1, 2 and 3, the top platen 18 and its support 22 are vertically movably mounted on carriage 23 by means of laterally oppositely disposed pairs of vertical screw shafts 49, 49, rotatably mounted between the side-member extensions 29 and bearings 50, 50 on the upper ends of the side members, the four screw shafts being received through threaded bushings 51 non-rotatably affixed in the corresponding corners of the platen support 22. Rotation of the screw shafts 49 in unison in either of opposite directions is effective to raise and lower the platen member 19 on the carriage. These screw shafts also serve as guide means for said vertical movement of the platen member in parallelism to the horizontal.
Power means 52 is provided on the carriage cross-head 27 for driving the four screw shafts 49 in unison, the same including a reversible electric motor 53 which through suitable bevel gear means 54, 54 drive a pair of horizontal shafts 55, suitably journalled on the cross-head. Bevel gear means 56, 56 at opposite ends of each shaft 55 drive the respective vertical screw shafts 49. The arrangement is such that operation of the motor 53 may be electrically controlled, in a manner to be described later, to raise and lower the platen member 19 from and toward positions corresponding to positions A to H indicated in FIGURES l to 7, which will be described in greater detail in connection with the operation of the machine.
The top platen member 18 may be releasably clamped on the platen support 22 to be swung from and toward the same for purposes to be described. Accordingly, the platen 18 and its support 22 may have, at the right-hand sides thereof, cooperating pairs of lugs or bifurcations 57, 57 and 58, 58, respectively, between which laterally spaced links 59, 59 are pivotally connected, so that the lower platen may be swung, as for example from the clamped position indicated at A in FIGURE 1, to the chain-dotted line position indicated at H in FIGURE 1. For locking the platen in clamped relation to the platen support 22, the left side of the platen member may have cooperating pairs of lugs 61, 61 and 62, 62, respectively on platen 18 and its support 22. In the clamped position, aligned apertures 63 and 64 in the cooperating lugs 61 and 62, respectively, may have a cylindrical locking pin 65 received therethrough, the pin being afiixed on the end of a plunger rod 66 of an electrically controlled hydraulic cylinder 67 on the platen support. That is, one such hydraulic cylinder 67 is provided for each pair of cooperating lugs 61 and 62 (see FIGURE 2).
On laterally opposite sides of the platen 18 may be a pair of trunnions 68 adapted to be supportingly engageable in the bearings 45, when the carriage has been moved to position D, and when the locked platen member has been moved downwardly on the carriage for that purpose. In the last mentioned trunnion-engaged position, the locking mechanism 67a is operable in a manner to be described later, to release the same so that the carriage 23 and the top platen support 22 thereon may be variously moved as described above to tilt the top platen from position E of FIGURE 5, through positions F and G of FIGURES 6 and 7, to the angularly inverted position H of the platen shown in chain-dotted lines in FIG- URE 1. Electrical control means for automatic and/or manual operation through these movements will be described in connection with the wiring diagram of FIG- URE 10.
The Lower Platen For vertically moving the lower platen 19 in parallelism, the same may be mounted on the upper end of laterally spaced movable support means 69, 69 which are vertically slidably guided in fixed slide means 70 on the frame 21. For vertically moving the platen in said slide means, the toggle mechanism 25 is connected between a fixed lug 73 on the frame, or in the lower portion of the frame, and lug means '74 aflixed on the underside of the platen 19. The toggle mechanism is operable from a collapsed position thereof shown in FIGURE 1 to a fully extended or pressure-applying position shown in FIG- URE 3, as by means of a plunger shaft 74 of a hydraulic ram 75 connected to the intermediate pivot point 76 of the toggle mechanism. The cylinder 77 of the hydraulic ram is pivoted to the frame at 78 to be swingable with movement of the toggle mechanism. Accordingly, the hydraulic ram 75 is operable through an electrically controled valve VA (see FIGURE 10), and while the carriage is stopped at the left of this pass, to move the lower platen 19 from and toward a relative position shown in full lines in FIGURES l and 2, to the pressure-applying position shown in FIGURES 3 and 4. During this upward movement of platen 19, guide cars 11, 11 on laterally opposite sides thereof engaged within channel-shaped, vertically extending guides 12, 12 affixed on the carriage side members 26, and thereby self-operatively to align platen 14 laterally and transversely with respect to top platen 16. This structure eliminates the usual necessity for having dowel pins on the die sections to assure accurate complemental registry of the same. Conversely, in the lowered position of platen 19, the ears 11 thereon are disengaged from the guides 12 to permit transverse movement of the carriage 23.
Other means than the hydraulic ram 75 and toggle mechanism 25 may be utilized to apply requisite strong operating force to the lower platen 19, in either direction. As an example, hydraulic rams or separate series of hydraulic rams may be utilized for moving the platen 19 to pressure-applying position and to retracting position, respectively.
Operation of the Press Operation of the press for spotting the sectional die or mold 15 will be understood by the following description in connection with the wiring diagram of FIGURE 10 and the drawings generally:
Setting up for Cycle of Operation of Press In setting up the machine or press for a cycle of operation, the operator first closes the Start switch to operate the pump (not shown) for the hydraulic ram 75, and sets selector switch H-A on Hand or manual operating position (see FIGURE 10). Hydraulic-Down switch H-D is now closed to make sure that the toggle-operating ram 75 has been operated through valve VA, to move lower platen 19 to its low or retracted position (see FIGURE 1). Now switch LS-l is closed to set a series of associated electrical circuits in condition for further selective press movement. The Platen-Up switch may now be closed to move top platen member 18c, including support 22, upward on carriage 23 from pre-selected position B, until it is stopped in position A on carriage 23 (FIGURE 1), by operation of a vertically adjustable switch LS-2 for any predetermined limit of such upward movement as required (see full-line position of LS2 in FIGURE 1). Carriage-Right switch is next closed to move carriage 23, with the upper platen member 18c thereon, from posiion A to the right, to centered position A of the carriage, shown in FIGURE 1, thereby to leave the bottom platen free and unobstructed.
Mounting Die on Press With the carriage retained in said A -position, the assembled two-part sectional die 15 is loaded on the lower platen 19, as shown in full lines at the left of FIGURE 1, and the lower section 17 of the die is clamped onto platen 19, as by means of clamps 19a. Now the Carriage- Left switch is held to move the carriage 23 back to position the top platen above die 15, where it is automatically stopped by engagement of a portion of the carriage with switch LS-6 on frame 20. The operator now closes the Hydraulic-Up switch, and thereby through a valve VA to operate the ram 75 and toggle mechanism 72, to urge the bottom platen 19 to its upward limit of movement. The Platen-Down switch now may be held closed as necessary to move top platen member 180 downwardly on the carriage until platen 18 rests on the top die section 17, or until a predetermined dimension corresponding to the exact height of the die is indicated, by a pointer 11c affixed to top platen member 18c, on a scale 11a provided on one carriage side member 26. In this position, indicated at C in FIGURES 3 and 4, the top die section 16 is affixed on the upper platen 18 by means of clamps 18a. Now hydraulic-down switch H-D is closed to lower the bottom platen, which closes switch LS1. The die-mounting cycle of operation is now complete, and the press is in condition either for an automatic cycle of operation, or for manually controlled operation thereof.
Carriage-Right Cycle of Automatic Operation of Press To start a Carriage-Right cycle of automatic operation of the press, the operator now sets selector switch H-A on automatic or Auto, thereby de-energizing latching relays AR and R7, and energizing Carriage-Right relay CR-1, and also energizing latching relay R1, by which latching mechanism 67a of platen member 18c remains locked to retain the upper platen 18 in superposed clamped relation on top platen support 22. Top platen member 18c, with male die section 16 thereon now travels up the carriage 23 until it engages switch LS-Z, to open an LS-2 N.C. contact and stop upward travel of the top platen member in position A, shown in FIGURE 1, in which the male die section 16 clears the female die section 17. Simultaneously the NO. contact of switch LS-2 closes and energizes relay R2, which locks itself in by one set of its contacts. When LS-2 N.O. closes as described, the carriage 23 starts to travel to the right, through the circuit containing LS-3 and contact R1, until the carriage engages and opens right-hand limit switch LS-3 N.C., to stop the right-hand movement of the carriage in position D of FIGURE 1. At the same time that LS-3 N.C. opens, LS-3 N.O. closes to de-energize latching relay R1, while relay R2 remains energized through closed LS-2 ND. The NC. contacts of relay R1, being now open, the top platen member 180 travels down until it engages switch LS-4 to open the same and stop said downward travel in position E of the top platen member in which the trunnions 68 thereon will be cradled in the upwardly presented bearing slots 45 (see FIGURE 5). At the same time the LS4 N.O. contacts close energizing R4 through relay contacts R7 and R3. Upon the trunnions 68 coming to rest in the bearing slots 45, platen 18 will engage switches LSS-L and LSS-R, to close N.O. contacts of the same to the platen-unclamping circuit for unclamping platen 18 through contact R4. The LSS-L NC. and LS5-R N.C. contacts are thereby opened to disconnect the R3 Unlatch or unclamping circuit. When unclamping has been accomplished, a switch LS8 N.O. will be closed to energize timer T-l. After a pre-set time the timer T-l will energize the R7 latching relay, by which one contact R7 energizes unlatching relay R5 and one set of R7 contacts deenergizes the R2 relay. Timer T-1 also energizes latch relay R3.
Now that relay R2 is de-energized and relay R5 is operated for unlatching the locking mechanism 67a, and relays R1 and R3 are energized, switch LS4 causes top platen support 22 to travel up the carriage from position E until the platen support engages switch LS-12, whereby LS-lZ N.C., opens and stops the upward travel of the platen support at a predetermined height as shown in position F of FIGURE 6. At the same time LS-12 N.O. closes to energize relay R-6 through contacts R3-R5, to
cause the carriage to travel to the left, until it engages a switch LS-16 previously rendered effective through contact R3 to open switch LS-16, to stop left-hand travel of the carriage in position H of FIGURE 1, in which the links 59 between top platen 18 and platen support 22 will have caused the platen to tilt on the trunnions 68, through the G-position of FIGURE 7, to the I-I-position of FIG- URE 1, wherein the top platen has been inverted to present the male portion 16 of die 15 upwardly at a convenient working angle. In this position an operator may prepare the die part 16 of a subsequent die-spotting operation in known manner, while die 17 is being likewise prepared at the other end of the press.
Carriage-Left Cycle of Automatic Operation of Press After preparation or treatment of the die sections 16 and 17 as described above (FIGURE 1), the operator closes return cycle switch RC, which energizes latch relay R5 through contact R7. Relay contacts R5 open the latch relay circuit and also drop out relay R6, to cause the carriage to travel to the right until it comes in contact with switch LS3. The contacts of LS-3 N.C. thereby open to stop right-hand travel in position F (FIGURE 6), while switch LS-3 N.O. closes to de-energize the unlatching relay R1, and through contacts R1 and R5, thereby closes the platen-down circuit, and causes the top platen support 22 to travel down the carriage until it engages switch LS4. This causes the LS4 N.C. contacts to open and stop this down travel of platen support 22, in superposed relation to top platen 18, which will then have been tilted back to its original E-position on the trunnion bearings 45 (FIGURE 5 Simultaneously, the LS4 N.O. contacts close, energizing R-10 relay through contact R5. Contact R-10 is thereby made effective, through ram 75 and toggle mechanism 72, to lock the top platen and its support 22 in clamped condition. After fully locked clamping has been accomplished, a plunger engages and closes switch LS-7 ND. and energizes timer T-2 through contacts R5. After a pre-set time, timer T1 energizes latch relay R7, and through contacts R7 opens latch relay circuit R5, while contacts R7 also energize unlatch relay R5 and stop operation of timer T-2. Contacts R5 also de-energize relay R10, and open the Platen-Down circuit and the Carriage-Rig t circuit and also energize latching relay R1, which closes the Platen-Up circuit to cause the top platen member 18 to travel up the carriage. In this movement, switches LS5R and LSS-R N.C., close the energized unlatching relay R3, and the platen member 18c continues to travel up until switch LS2 is engaged, thereby to open contact LS2 NC. and stop the upward travel. At the same time contact LS-Z N.O. closes and energizes relay R6 to cause carriage 23 to travel to the left until it engages switch LS-6, which stops left-hand travel of the carriage with the top die section 16 in position A (FIGURE 1), directly over bottom die section 17. This ends the automatic operation, and the operator now sets selector switch H-A in the Hand position.
At this point, the two die sections 16 and 17 may be clamped together to test the accuracy of article-forming surfaces thereof by various known methods, such as by means of forming an article of suitable checking material in the die, and subsequently checking the formed article. Such clamping of the die sections is accomplished as previously described, namely by closing the hydraulic-up switch H-U, and thereby through valve VA to operate ram 75 and toggle 72, tourge bottom platen 19 to the positive upward limit of movement thereof. Now Platen-Down switch is momentarily held closed as necessary to move the upper platen member down the carriage until the upper die section 16 is complementally engaged with the lower die section 17 to form the article (not shown). This movement may also be checked by the position of pointer 11 with respect to scale 11a (see FIGURE 2). Upon allowing the article to harden the ram and toggle are reversely operated, as described above, forcibly to separate the bottom die section from the top die section, after which the press may be set to repeat the aforesaid automatic operation and return the lower die section to the H position thereof shown at the right of FIGURE 1.
Accordingly, the top and bottom die sections 16 and 17 again will be presented freely upwardly at the righthand and left-hand ends of the press, respectively, whereby an operator or operators may conveniently work on the respective die sections to check the same and the test article made therein, and may correct the dies as necessary. The automatic cycles of operation, through the various positions B to H and return, may be repeated as often as necessary to condition the die for use in continuous production in another machine, without the necessity for removing the die sections from the respective,
platens at any time during the testing or checking cycles of operation of the press. Any modifications, such as grinding operations, which may be required in the two die sections likewise may be accomplished simultaneously while the top die section is in the H-position of FIGURE 1.
The press can be stopped at any time during the right and left cycles of automatic operation, by means of the emergency stop switch ES. By depressing Cycle-Start switch C-S, the press will continue the automatic cycles from the points where they were stopped. If the operator should, for any reason, be required to reverse the direction of a particular operation, from that which the corresponding position of the cycle dictates, he may do so by setting the selector H-A switch for Hand or manual control.
Manual or Hand Operation of Press Any of the various movements of the press, accomplished as described for automatic operation, may be accomplished individually by means of the respective manually operable switches for Hydraulic-Up, Hydraulic- Down, Platen-Up, Platen-Down, Carriage-Right, Carriage-Left, Clamp and Unclamp. These switches, as well as the switches for Emergency Stop (ES), Cycle Start (Cfis), Selector (H-A), and Return Cycle, may be located in a control box 12 on the lower end of a downturned extension 13 of an arm 14 pivoted on the cross-head 27 of the carriage. The arrangement is such that the control box may be moved in a wide are around the carriage 23 for maximum convenience to the operator during various phases of operation of the press.
The clamping mechanism, however, cannot unlock, except under safe conditions. That is, the upper platen 18 and platen support 22 therefor must be fully supported in superposed relation by the trunnions 68 resting in the bearing recesses 45, whereby the safety switches LSR and LSS-L will be held open, as previously described. There is also a safety feature in the hydraulic ram 75, in that it cannot be operated to move the lower platen 19 either up or down unless the carriage 23 is in the extreme left-hand position of FIGURE 1 to close switch LS-fi.
Modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claims.
