- Each bore 12 is on the surface to be facing the other plate provided with a surrounding circular guide recess 14 for receiving a connecting bar 16, as is most clearly shown in Figs. 4 and 5 and as will be explained below.
- the number of the bores depends on the size of the press. All bores 12 have the same diameter and all recesses 14 have the same diameter and depth.
- the front plate 4 and the rear plate 6 are identical as regards the size and position of openings and bores. All bore surfaces are finished to achieve a smooth surface impeding formation of cracks.
- the spacer elements comprises ten solid circular connecting bars 16 having a predetermined length. These bars are acting as spacers between the front and the rear plate 4, 6 as well as means for connecting the plates together.
- All bars have a center part 16b with a larger diameter D 2 and end parts 16a with a smaller diameter D 1 .
- the length of the center part 16b is exactly the same for all bars in order to constitue spacers between the front plate 4 and the rear plate 6. Further the smaller diameter end 16a of all bars have the same diameter.
- All the connecting bars 16 are connected to the plates in the same way.
- the smaller diameter ends 16a of a connecting bar 16 are inserted with a tight fit in a pair of aligned bores 12 in the front and the rear plates 4 and 6.
- an end surface of the larger diameter center part 16b of said bar is abutting a recess bottom surface surrounding said bore.
- the recess bottom surface forms a plane surface for receiving the connecting bar 16 in a right-angled fashion.
- the circular recess 14 has a slightly larger diameter than the larger diameter center part 16b.
- each connecting bar 16 is attached to respective plate by means of a screw 18 with a washer 20 fastened in a corresponding threaded hole in the smaller diameter end 16a. There is a clearance 22 between the washer 20 and the plate 4 enabling the plate to be properly biased against the connecting bar 16.
