Description

Die setting and line casting machine, in which the in the mold cast line is trimmed by a foot knife. As is well known, in matrix setting and line casters - the line cast in the mold through a foot pruning (knife brought to the right height when working this so-called The greatest accuracy of the foot knife is required, as there are only small differences in height stand out in the lines when printing and make the whole print appear unclean. Small differences in height can arise when the mold carrier passes by there is no precise guidance of the two parts against each other on the foot knife. The guides previously provided for this purpose are now carried out in accordance with the invention improved in that a roller guide is provided, which the mold carrier secures against any evasion towards the knife. One can use the roller guide can be adjusted in order to compensate for margins caused by wear and tear. -, In the drawing are several exemplary embodiments of the invention shown, namely: Fig.z a view from behind of the mold carrier, Fig. Z is a view from the right of Fig. R. Fig. 3 is a plan view of the leadership of the Mold carrier, Figs. 4 and 5 each show two further embodiments the guidance in the plan.

The illustrated embodiments relate to matrix setting and line casting machines of known design, in which a rotating, the casting mold containing gear is used, which is driven intermittently. Naturally the invention is also applicable to other types, including those with straight lines and pouring molds moved here and those, l: where the knife executes the movement, while the mold is stationary, and the like can be used.

The casting wheel a carrying the casting mold b is, as usual, mounted on a pin which is carried by the casting wheel slide c. The casting wheel slide carries in a known manner the knife d which is used to trim the line footer.

In order to prevent the casting wheel from deviating from the knife when the line is trimmed, according to the invention, a bracket e @ is attached to the casting wheel slide in the vicinity of the knife d. This bracket carries rollers f and g, which are used to guide the casting wheel while the knife is being cut. The roller f is immovably mounted in the bracket by means of its pivot 1a, it lies against the rear side of the casting wheel, that is, the side on which the knife is also seated. In order to be able to adjust the position of this role precisely, the bracket e is slidably attached to the carriage c; it is guided on it by means of a groove and is tightened after correct setting by the clamping screw i. The rollers a, two of which are shown in the drawing, lie against the outside of the gearwheel and prevent it from deviating outwards, that is to say away from the knife d. These rollers are arranged on angularly bent pins k, which pass through bores in the bracket e and are held in their position by nuts. By adjusting these nuts ;; i. the roller g can be adjusted so that it guides the gear exactly and any deviation outward during the cutting of the line by the knife is excluded.

Instead of the fixed setting of the roller g by the nuts m can also the embodiment shown in Fig. 4 can be selected, in which the Bolt k by a spring ii., Which is on one side against the bracket c, on the other side against a collar o attached to the pin k, in contact is held on the casting wheel. The springs 7a must of course be so strong; that they prevent the casting wheel from deviating while the line is being trimmed.

To prevent rotation of the pin k in the bracket e, the Insert the bolt into a slot q in the guide using a pin p.

If you want to make the spring pressure of the springs n adjustable, you can According to Fig. 5, instead of the collar, provide adjusting nuts r 'which on the with Threaded end of the bolt k are fitted and an adjustment of the pressure enable the springs 7a.

Compared to the known guides, the one described above has in particular, the advantage that there is no rapid wear of the sliding surfaces can and that, in the event of such wear and tear, a simple adjustment is possible is.

One can, if the casting wheel is made of soft metal, that Reduce wear even further by the fact that at the points of the, casting wheel, with which the rollers come into contact during the cutting process, hardened steel plates touches down.

Claims (3)
