4 Claims.
Use is made, for the purpose of stamping dies for the stereotyping process, of presses designed in such a manner as to apply a high pressure. Dies to be employed for shaping stereos must be pressed in a uniform manner, and possess a uniform thickness, so as to avoid, as much as possible, the making-ready operations connected with the preparation of the die, of the cast stereo, and lastly on the printing machine itself. Inequalities of the thickness of the dies may be caused, for instance, by the fact that the mould to be shaped is not placed exactly in the middle of the table of the stamping press, or, in the case of autotypes, for example, which, as is well known, require a higher pressure than composition by the fact that the distribution in the mould is irregular or one-sided.
In accordance with the subject-matter of this invention, for the purpose of removing these in- 20 conveniences, the movable stamping part of the stamping press is fitted with long guides, which are suitably designed to extend over practically the full height of the press. Lead stampings, which, as is well known, require a high pressure, and a particularly clear-cut and uniform impression, can also be made with stamping presses fitted with a device in accordance with the subject-matter of this invention. For the production of lead stampings, use was hitherto made of the well-known Albert fractional stamping process, in which the work is carried out only by stages, and which implies the use of presses of special type, fitted with the necessary devices. The stamping operation itself is of long duration. When, however, use is made of presses fitted with a device in accordance with this invention, the stamping can be carried out in one operation. Time can thus be saved, and the necessity of purchasing a special press for lead stamping purposes avoided. A further advantage of the application of the subject-matter of this invention is to be found in the fact that blurring, which is particularly liable to occur if either the table or the head of the press work out of true, is there- 45 by avoided. It is evident that other materials can also be pressed. This invention can also be applied to hydraulic die-presses, the plunger being lifted clear of the guides of the table, with which it need only be connected loosely.
The drawing hereto attached, and to which reference is made, illustrates, by way of an example, two modes of execution of the subjectmatter of this invention on presses, as follows:
Figures 1 to 3 show a mechanically-operated press, Figure 1 being a front view; Figure 2 a side elevation; and Figure 3 a section through the guides.
Figures 4 and 5 show a hydraulic press, Figure 4 being a front view; Figure 5 a side elevation; and Figure 6 a section through the guide.
The press-frame 1 of Figures 1 to 3 is fitted, for example, with four guides 3, 4, 5 and 6, connected with the table 2 operated by toggle levers 12 and 13. These toggle levers may be worked by a drive of any description. The table 2 carries, for instance, the composition S to be pressed. .The pairs of guide bars 3 and 4 and 5 and 6 are stiffened by transversal connections 7 and 8 operable through slots 9 and 11 in the press frame 1.
The device described above may be fitted not only on presses with a movable table, as in the case of the modes of execution referred to, but also on presses with a movable head. v
In Figure 4, part 15 is the frame of the press. The table 16 is operated by a plunger 17 worked by a liquid of any description. With the table 16 are connected guides 18 and 19, which can be stiffened and combined into a frame 24 by means of connecting parts 20, 21, 22 and 23. This frame 24 slides along the surfaces 26, 27, 28, 29, 30, 31 32 and 33 of the frame 15. The frame 24 is adjustable in the direction of the sliding surfaces 30 and 31 and 32 and 33, by means of the connecting parts 20. 21, 22 and 23. Auxiliary strips 35 and 36 are provided for the purpose of adjustment in relation to the sliding surfaces 27 and 28, and, 26 and 29. The plunger 17 is completely independent of the guide of the table 16, with which it need be connected loosely only. Such a connection may consist only of a ball 3'7 and of a cap 38.
I claim:
1. Gui-ding means for the press table of a die stamping press comprising a pairof guide elements fixedly secured to the press table at the rear and having plane surfaces in direct sliding engagement with plane surfaces of the frame of the press at opposite sides of the rear portion thereof, respectively, and another pair of guide elements fixedly secured to the press table at the front thereof and having plane surfaces in direct sliding engagement with plane surfaces of the frame at opposite sides of the front portion thereof, respectively, all of said guide elements extending above and below the press table and being of a length substantially equal to the height of the press frame.
2. Guiding means for the press table of a die stamping press comprising a plurality of guide elements fixedly secured to the press table and 3. Guiding means as set forth in claim 1 in which connecting members rigidly connect the guide elements of the respective pairs.
4. Guiding means as set forth in claim 2 in which connecting members rigidly connect certain of the guide elements.
