DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0044] A tool slide 1 according to the invention has a slide bed 2, a slide body 3, and a driver 4.

[0045] In the case shown, the slide part 3 is arranged so that it is suspended on the slide bed 2; the slide part 3 can be lifted up from the driver 4. The driver 4 is usually positioned on a first tool half (the lower one in the case shown), while the slide part 3 is positioned above the slide bed 2 on a corresponding second (upper) tool half (not shown).

[0046] The slide bed 2 is embodied as approximately box-shaped and has an elongated rectangular groove 5; next to the elongated rectangular groove 5, screw holes 6 are provided to accommodate corresponding screws (not shown). The groove and the adjacent surfaces 7 delimiting the groove form a bearing surface for L-shaped slide strips 8, which rest on the surfaces 7 and extend into the groove with one L-leg 9. The L-shaped slide strips 8 have mounting holes 10 for screwing in mounting screws for insertion into screw holes 6.

[0047] The L-shaped slide strips 8 have diverging surfaces 11 oriented toward the groove center with which they delimit a prismatic intermediate space between themselves. Toward the slide body 3, the L-shaped slide strips 8 have slide surfaces 12, which are embodied as flat and are oriented perpendicular to a depicted x axis 13.

[0048] Toward the surfaces 12, the slide body 3 has corresponding slide surfaces or slide strips 14, which are embodied as sliding partners for the L-shaped slide strips 8.

[0049] Symmetrical to the vertical axis, a guide part 15 embodied as a tongue 15 or guide stud 15 extends upward between the slide strips 14 and into the groove 5, In particular, the guide stud 15 has a prismatic cross-section, In this case, the guide stud 15 has elongated prismatic surfaces 16 with which it can rest against the surfaces 11 of the L-shaped slide strips 8.

[0050] Oriented toward the driver, the slide body has other slide strips 17, which are inclined relative to the x axis 13 and correspond to prismatic slide surfaces 18 of the driver 4. The strips 17, because they are connected to the slide body, constitute liftable slide strips, which are brought into an operative connection with the surfaces 18 when the upper pan and bottom part of the tool are brought together.

[0051] Since the guide surfaces of the L-shaped slide strips 8 and the corresponding surfaces 12 of the strips 14 are perpendicular to the x axis 13 and are also perpendicular to the guide stud 15, this embodiment is referred to as a so-called flat guide.

[0052] The roof-like inclined corresponding sliding elements 17, 18 between the slide body and driver form a so-called prism guide.

[0053] Since it is necessary to achieve an exact fit and guidance of the tool slide, particularly between the slide bed and the slide body, the guidance of the slide body in the slide bed must be adjustable or more precisely, the slide strips 8 and guide stud 15 must be adjusted relative to one another.

[0054] To this end, (FIGS. 2 through 5) the mounting holes 10 in the slide strips 8 are embodied as oblong holes so that the strips can be moved along the mounting screws 20 and thus along an adjustment direction 21.

[0055] The movement of the slide strips 8 along the direction 21 does not change anything yet with regard to possibly existing gaps or spaces between the surfaces of the slide strips 8 or L-legs 9 and the surfaces 16 of the guide stud 15. With regard to the longitudinal span or the direction 21, therefore, the contact surfaces 22 of the L-legs 9 of the L-shaped slide strips 8 on the slide bed 2 are inclined. This means that the short L-legs 9, which protrude into the groove 5, are embodied as slightly wedge-shaped relative to the direction 21 and change in thickness over their longitudinal span. The wedge shape or inclined surface has a slope of 1-5 degrees, for example.

[0056] The contact surfaces 11 on the L-legs 9 of the L-shaped slide strips 8 are oriented toward corresponding surfaces 16 of the guide stud 15.

[0057] To adjust the play, the groove site walls 19 are also embodied with corresponding inclined surfaces or are embodied as inclined in wedge-like fashion. A sliding along the direction 21 therefore causes the slide strips 8 to move toward the guide stud 15 or away from it. Since this simultaneously causes the slide strips to come closer to each other or move farther away in the transverse direction, i.e. the direction 23, the oblong boles 10 are embodied so that they also enable a floating support in the direction 23 around the screws 20.

[0058] Because of the corresponding inclined surfaces 19/22, a movement along the direction 21, therefore causes the distance between the L-legs 9 and the surfaces 16 to be reduced or eliminated. In this case, it is possible for both of the slide strips 8 to be moved or for only one slide strip 8 to be moved.

[0059] In order to adapt the slide strips 8 to the guide stud 15 and thus also to adapt the exact position of the slide body in the slide bed, it is possible, for example, to perform the adjustment from a stop position. of the screws 20 in the oblong holes 10 (FIG. 4). In this open adjustment (FIGS. 4 and 5), there is a gap 25, for example, between a corresponding wall 16 (FIG. 5) of the guide stud 15 and the corresponding wall 11 of the slide strips 8.

[0060] If the L-shaped slide strips 8 are then slid in the direction 21 (FIG. 2), then the gap 25 is closed by means of the inclined surfaces 11 (FIG. 3).

[0061] As explained above, this can be used to adjust a production-induced offset between the slide bed with the slide part in the upper part of the slide and the driver in the lower part (FIGS. 6 through 8).

[0062] To this end, the slide bed with the slide part is mounted on the tool with play between the slide strips 8 and the guide said 15. The gap dimensions between the corresponding surfaces 11 of the L-legs 9 and 16 of the guide stud 15 therefore each have a respective gap with a gap dimension that depends on the slope of the inclined surface, the production tolerances, and the position of the slide parts relative to one another. After the slide strips 17 are placed onto the driver 4, a production-induced offset between the slide bed with the slide part on the one hand and the driver on the other is compensated for. The slide centers itself. in this centered state, the L-shaped slide strips 8 can still be slid further so that finally, in the contacting state, the guide play and the gaps are eliminated. This ensures that even in the brought-together state of the press, extremely strict tolerances are set by means of the movable slide strips.

[0063] In the brought-together, centered state, the consequently adjusted guide play is still ensured by a fixing device 26. The guide play therefore no longer changes during the opening of the tool and thus of the tool slide.

[0064] Such a fixing device 26 is shown in various embodiments in FIGS. 13 through 16.

[0065] By way of example, FIGS. 15 and 16 show the guide strip 8, whose length is embodied so that one of the oblong holes 20 with the fixing screw 27 at the back end of the slider is uncovered in the brought-together state and the position of the slide strip 8 can thus be fixed by means of the screw.

[0066] FIGS. 13 and 14 show another solution for the positioning of the fixing device 26. In this depiction, a screw 29 inserted into a counterbore 28 of the slide strip 8 through an oblong hole 30 engages in the slide bed 2, and an underlying check element 31. The check element 31 can be slid into position by means of an adjusting screw 33 connected to a thread 32, thus adjusting the position of the slide strip 8. The tightening of the screw 29 in the slide strip 8 clamps the latter in the slide bed 2 by means of the check element 31, Which results in a securing of the adjusted guide play. Other fastening elements of the slide strip are accessible after the parts of the slide are moved, apart.

[0067] In the invention, it is advantageous that the adjustable slide strips and their L-shaped form on the one hand and the prismatic guide stud 15 on the other achieve a very compact, but also very stable guidance of the slide body 3 in the slide bed 2 and in addition, extremely strict tolerances can be set in a simple way.

[0068] The invention thus relates to a tool slide, in particular a wedge drive, which has at least one slide bed 2 and one slide pan 3; the slide part 3 is supported on the slide bed 2 in sliding fashion and in order to absorb transverse forces, a groove 5 and a stud 15 protruding into the groove are provided, which restrict a transverse motion of the slide part 3 in the slide bed 2; between the stud 15 and the groove 5, at least one sliding element 8 is provided; a driver 4 is provided that can be removed from the slide part 3 and between the slide pan 3 and the driver in the contacting state, there is a prism guide composed of inclined elements 17 of the slide body 3 and corresponding inclined surfaces 18 of the driver 4; and between the slide bed 2 and the slide body 3, as flat guide is embodied so that the sliding elements 8 of the slide bed 2 and corresponding sliding elements 14 of the slide body 3 are perpendicular to the an x axis 13, thus enabling a movement transverse to the x axis 13.

[0069] The invention also relates to a tool slide in which the sliding element 8 has a wedge-like, inclined surface 22 oriented toward the groove 5 with which it rests on a corresponding surface 19 of the groove wall 5 and the corresponding groove wall 19 has a corresponding wedge-like inclined surface so that an axial movement of the sliding element 8 in a longitudinal direction 23 reduces or enlarges a gap 25 between the stud 15 and the sliding element 8.

[0070] The invention also relates to a tool slide in which the sliding elements are L-shaped slide strips 8 or slide plates 8, which have surfaces 11 oriented toward the groove center with which they delimit an intermediate space between themselves and, oriented toward the slide body 3, have slide surfaces 12, Which are essentially flat and perpendicular to an x axis 13; the guide part 15 or the guide stud 15 extends upward into the groove 5 symmetrically to the vertical axis; and the guide stud 15 has elongated surfaces 16 with which it rests against the surfaces 11 of the L-shaped slide strips 8.

[0071] The invention also relates to a method for compensating for a production-induced offset in a tool slide, in particular a tool slide; the tool slide includes a slide bed 2, a slide body 3, and a driver 4; between the slide body 3 and the driver 4, a self-centering guidance is provided, which when the slide body 2 is placed onto the driver 4, centers the slide body 3 on the driver 4 transversely to an x axis 13, and the slide body 3 is supported on the slide bed 2 in a floating fashion transversely to the x axis by means of a fiat guide so that the production-induced offset is compensated for as part of the centering of the slide body 3 on the driver 4 in the transverse direction; and after the compensation of the production induced offset, sliding elements 8 between the slide bed 2 and the slide body 3 are slid and adjusted so that the slide surfaces rest in form-fitting fashion against a stud 15 protruding into a groove 5 along the x axis 13 and thus the floating support transverse to the x axis 13 is canceled.
