る。DETAILED DESCRIPTION OF THE INVENTION Due to the structure of the frame of the C-type frame press machine, the frame deforms (opens in the front) as shown by the dotted line during processing (FIGS. 1 and 2). At this time, the machining center line a is rotated by a certain inclination amount θ with Q as the rotation center, as indicated by a'. As a result, the punch P and die D become misaligned (Fig. 8), causing mold galling at part K. The production line must be stopped to repair the mold that caused mold galling, resulting in large costs to the company. causing damage.

（図１０，１１，１２，１３）でもよい。 In other words, in a C-frame press machine in which the slide SS is attached to the slide sliding surface S provided on the front surface of the C-frame F in a normal manner so that it can slide up and down, the The convex surface of a cylindrical bolster V (Figs. 4 and 5), which has approximately the same curvature, is placed front and back on the concave surface of a cylindrical bed B (Fig. 3), which has a curvature approximately centered around the rotation center Q determined at the position of . The rod L fixed to this cylindrical bolster V can slide precisely within the rod guide hole G provided in the frame F near the sliding surface S (Fig. 6, 7). (Figure 1,
2, 3, 6, 7, 12, and 13, the slide, connecting rod, gear mechanism, etc. were omitted, but only the slide SS was written in Fig. 6. ) Note that the sliding surfaces (concave and convex surfaces) of the cylindrical bed B and the cylindrical bolster V, as well as the sliding surfaces of the rod L and the rod guide hole G, are shown as the sliding surfaces of a sliding bearing in this figure. , the sliding surface may use many bearings such as rolling bearings. Further, the bed and the bolster may be spherical (FIGS. 10, 11, 12, 13).

ス機械と同等の強さ（剛性）を発揮する。 Therefore, even if the frame opens forward during machining and the machining center line rotates from a to d', the cylindrical bolster V also rotates around Q as shown in Figure 9, so the punch P and die D misalignment does not occur and mold galling does not occur. In addition, since the slide SS slides on the sliding surface S provided on the frame F, it exhibits the same strength (rigidity) as a normal press machine against eccentric loads and impact vibrations during processing.
