PATENTEU MAY 1 8157! SHEET 3 OF 3 V v Qu l vAniAsLr. PRESSURE EMBOSSING MACHINE Embossing machines in the past have produced designs in intaglio or in relief on metallic plates or bands by virtue of the passage of the metal between two embossing cylinders or rolls. The embossed design on the cylinders is imprinted in the metal under the pressure with which the two cylinders are forced together. In embossing machines of this type having hydraulic power cylinders pressing the embossing cylinders together, the engaging pressure has been varied by means of metallic wedges between the bearing blocks of the cylinders. These prior art arrangements have the disadvantage that the engaging pressure of the embossing cylinders cannot be varied at will, particularly the pressure at one axial end of the cylinders cannot be varied separately from the pressure at the other end in a convenient manner.
It is an object of the present invention to provide embossing machines of this type that will overcome the above disadvantages and provide for easy and simple adjustment of the engaging cylinder pressure.
The embossing machine of the present invention has embossing cylinders that are pressed together under the constantly applied force of main hydraulic power cylinders acting upon their bearing blocks at the respective axial ends. The resultant engaging force of the embossing cylinders is varied by means of control hydraulic jacks placed between the respective bearing blocks of the embossing cylinders at their opposite axial ends; the jacks at each axial end are controlled separately by means of ram-type hydraulic pistons driven by means of a motorreducer drive group so that the pressure of the jacks may be controlled effectively, easily and independently at each axial end.
Other features, advantages, variations and modifications of the present invention will become more clear from the following detailed description of the drawing wherein:
FIG. l is a somewhat schematic side elevation view of the embossing machine according to the present invention;
FIG. 2 is a somewhat schematic longitudinal front elevation view of the embossing machine according to FIG. 1',
FIG. 3 is a schematic hydraulic circuit diagram for the controls of the FIG. l machine;
FIG. 4 is a somewhat schematic detailed representation of a control jack showing its means for retracting it during changing of the embossing cylinders; and Y FIG, is a partial cross-sectional view taken along line V-V of FIG. 4.
As shown in FIGS. 1 and 2, the embossing machine is provided with rigid upright supports or columns I and la at the respective axial ends of the machine. These supports are somewhat U-shaped, opening upwardly and are closed at their top ends by the transverse frame members 2 and 2a, respectively. The embossing cylinders or rolls 3 and 4 are provided with axially opposite bearing blocks 5, 5a and 6, 6a respectively.
The opposite axial bearing blocks 5 and 5a are relatively fixed to the frame and the lower bearing blocks 6 and 6a are mounted for vertical reciprocation. The bearing blocks at each axial end of the machine 5, 6 and 5a, 6a are separated by means of control hydraulic jacks 8, 9 and 8129a respectively to provide a predetermined stressing or preloading of the embossing cylinders away from each other. The lower bearing blocks 6, 6a are forced toward the upper bearing blocks 5, 5a by means of the main hydraulic power cylinders 10, a, respectively.
The hydraulic control circuit for the preloading jacks and main hydraulic power cylinders is shown in FIG. 3. The control hydraulic fluid is delivered from the supply under pressure through the main conduit 19 that provides pressurized fluid for the main hydraulic power cylinders 10 and 10a, on the one hand, and supplies hydraulic fluid for the jacks 8, 9 and 8a, 9a with their ram pistons 11, 11a respectively, on the other hand, which have the function of regulating the hydraulic pressure within the preloading jacks 8 and 9, 8a and 9a. The pressure accumulators I4 and 14a are mounted respectively in the pressurized hydraulic supply lines for the main power cylinders 10 and 10a.
Each of the jack ram pistons 11 and 11a is controlled by means of a motor-gear reduction drive group I2 and 120, respectively. Such motor-gear reduction drive units are conventional, as described in French Pat. Nos. l,2l3,820 and 1,356,340. These groups may operate independently to produce independent hydraulic prestressing signals or they may be coupled together by means of the clutch 13 operatively connected between the axially aligned shafts 20a. By this means, the opposite axial ends of the embossing cylinders may be provided with the same prestressing force or with different prestressing forces. Suitable valves L and M are provided in the circuit along with pressure gauges N and P to maintain the desired operation. The opposite axial ends of the machine have been shown side-by-side in FIG. 3 along with their jacks and main power cylinders for purposes of illustration.
The hydraulic supply includes a fluid reservoir 22 for the hydraulic fluid, for example, oil, a pump 24 to provide a constant output or supply in a single direction toward the jacks and main hydraulic power cylinders through the appropriate valve A through G such as stopcocks, which are well known in the art, and a motor 23 for driving the pump 24. Once, the hydraulic fluid has been delivered to fill the pressure chambers of the jacks as well as the connecting conduits, valves A and B are closed, while the remaining valves are in an open condition. The hydraulic fluid is delivered to the pump 24 through the filter 25. A pressure limiter or regulator 27 is provided in the main conduit 19 and has a hydraulic return line passing through the cooler 26 to the reservoir 22.
The two jack ram pistons 11 and Ila serve the purpose of supplying to or withdrawing from the jacks 8, 9 and 8a, 9a small quantities of fluid so as to produce a variation in response to the requirements of the preload of each side of the cylinders of the embossing machine. The plunger pistons 110, 1100 of the jack ram pistons 111, 1110 terminate in endless screws Ill, 111a, respectively, each being dependent upon a helical wheel H2, 1120, respectively. The helical wheels I12, ll2a are driven by motor- gear reduction units 12, 12a which include electric motors engaging the corresponding helical wheel by means of a reduction gear train. As before mentioned, the axially aligned shafts 20, 20a are coupled together by means of the clutch 13.
Another particularly advantageous feature of the invention relates to the mounting of the above described components so that the embossing cylinders may be easily removed and replaced. As shown in FIG. 1, the transverse frame members 2 and 2a are secured to the upright supports 7 and 7a by means of bolts 21 and 2111, respectively. By removal of the bolts 21 and 21a, the respective transverse frame members 2 and 2a may be removed to allow upward removal of the embossing cylinder 3 with its bearing blocks 5 and 5a. Also, the control hydraulic jacks 8, 8a, 9, may be retracted by means of the mechanism shown in FIGS. 4 and 5 so that the lower embossing cylinder 4 and its associated bearing blocks 6 and 6a may likewise be removed in the upward direction.
As shown in FIGS. 4 and 5, the jacks 8, 8a and 9, 9a have been illustrated in full lines in their normal working positions; dotted lines have been used to indicate the retracted position of the illustrated jack. Only one jack is illustrated, because they are all substantially identical. For retraction, the jack is mounted on a supporting arm 16, which is mounted for pivotal movement about the pivot pin 17'. The supporting arm 16 and its associated jack is locked in either its horizontal normal position or in its retracted dotted line position by means of an indexing pin 18 that engages a correspondingly aligned bore for locking and is removable therefrom for pivoting of the arm 16.
A stationary hydraulic coupling 28 provides connection between the flexible hydraulic conduit 29 leading to the respective jack and the rigid supply conduit 30 that receives hydraulic fluid from the hydraulic supply 15.
