The present invention relates to a new arrangement for die setting machines with loose matrices and exclusion wedges guided in a circuit on rods. The invention is shown in Figs. Fig. Ι is a perspective overall view of the essential parts of the invention in two different working stages in side view partial cut. Figures 4 through 6 illustrate details.

The matrices A, which can be provided with several images, as assumed in the drawing, arrive in a known manner, for. As by their own weight (Fig. 1), in the range of a Ff Stöfservorrichtung ^1/2/3 * to be pushed according to the intercepted to be set mark in various altitude and behufs Stöfservorrichtung by the formation of the line to the side /. The dies are lined up with corresponding guide grooves a ^{1 on} their lower edge on a rail c ¹ which protrudes from a fixed table top C. The latter is appropriately inclined towards the horizon.

The rear ends of the exclusion wedges B are on guide rods b ^l b ^x , which they encompass with cutouts b. Such guide rods are expediently arranged on both sides of the table C in such a way that two groups of exclusion wedges are used. The guides b ^l b ^x are firmly connected to the table C.

As can be seen from Fig. 1, the exclusion wedges B are supported against a tab b ^{2 of} the table. They are triggered by the double keys b ^r > δ ° shown in FIG. 6, which are hinged to a lever b ³ , while rods b ^l b * also hinged to this lever lie in the area of the respective foremost exclusion wedges. By alternately striking the buttons b ⁶ , an exclusion wedge per group is alternately triggered in this way. The triggered exclusion wedge falls with its front end on the table C and lies in the path of the collecting dies. In this way, the line shown in FIG. 1 arises with the gradual advancement of the collecting matrices and the exclusion wedges. When the line is formed, the outermost die is supported against a plate H shown in FIG. 4 (longitudinal section through FIG. 1) which, by means of a rod h, engages a lever / 2 ¹ h ^z and recedes to the left to the same extent as the line advances.

When the matrices and exclusion wedges of a row are together, the worker lifts the plate H, places it against the end of the line and now pushes the matrix line onto the movable table adjoining C / (Fig. I) by means of the plate H. A guide rail ζ ' ⁹ protruding from the latter forms the extension of the guide ^{rail c 1} in such a way that the dies open when stepping over

Claims (1)

table I cannot change their mutual position. The exclusion wedges B step with their guide openings b on guides / over which are carried by movable swing arms L and when the line is transferred from c to / lie exactly in the extension of the guide rods b ^l (see also Fig. 2 and Fig. 5, section after xx of Fig. 1). When the line was shifted onto the movable table I , the abutment i ³ visible in FIG. 4 fell down so that its upper end intersects with the plane of the tables. The die line is supported on the left against a slide H ¹ under spring pressure h ⁶ . If the die line arrives in this way with the intermediary of the plate H, as described, with its left end in contact with the stop i ^{2 of} the table /, the stop i ^s is raised again, e.g. B. by the lever ft ³ , in such a way that the die line is now under the influence of the spring-loaded slide H ' leans against the upper end of the stop z ³ and this is thereby raised. The table is now raised / against the forming wheel M (FIG. 2) and, at the same time, the exclusion wedges are driven in for the purpose of spreading the line, by the following means. In the guide shaft i of the table / moves a plate z '°, which on the one hand ^{carries the previously mentioned guide rail z 9} , on the other hand is hinged to a lever i * (FIG. 3). This lever rests with a roller z ' ⁵ on the edge of a cam plate z' °, in such a way that when the cam plate rotates, lever z ⁴ rests in time and praises the table / with the die line on it against the forming wheel M. The aforementioned swing arms L, which carry the guides /, are ^{hinged to lever Z 1} (Fig. 2 and 3), the latter are rotatably mounted in the guide shaft i of the table / and with their lugs on the plate i ¹⁰ in the Fig 2. Support as can be seen in that the levers Z ^{1 are} under the pressure of spiral springs Z ² . The arms L are connected by tie rods Z ³ to a two-armed lever Z ⁴ which is mounted in the shaft i ^{at Z 5} and which also carries a weight ^{on an arm / 6.} The double lever Z ⁴ for its part is finally connected by a tie rod Z ⁷ to an angle lever Z ⁸ , the second arm of which is pressed against a cam disk P with a roller. When the cam plate Z ⁹ revolves, the weight on the lever Z ⁰ comes into effect and thereby causes the arms L to swing inward and thus the two-sided driving of the exclusion wedges into the line. This process takes place when the table / the form wheel has almost reached it, whereby at the same time the exclusion wedges B, which up to that point rose diagonally from the line, are aligned with the matrices to the line by pulling the arms L against the pressure of the springs Γ ² be pushed down. The Giefstopf N lies against the mold slot, and now with the position shown in Fig. 3 of the parts of the Gufs of the line. After the end of the casting, the table sinks back into its starting position in two paragraphs. In the first paragraph, the table reaches a height at which the table top / with a channel w ¹ (Fig. 3) cuts off and the guides Z are exactly in the continuation of the guides b ^x (Fig. 1). The springs Z ² come back into effect and ventilate the Ausschlufskeile B in such a way, that below the same the u access to the serrations a ~ (Fig. 1) of the matrices there is provided specifically for the purpose, that in the channel ^l movable offshoot the matrices in the cutouts detect it and the whole Matrizenzeile can pull up to the lapping apparatus. Simultaneously with the ventilation of the Ausschlufskeile B, the guide rail is retracted z ⁹ due to the noses of the levers Z ¹ ', such that Matrizenzeile DAF by the offshoot first aligned, then can be comprehended, and finally pulled up. As soon as the die line has been removed, hook bars V (Fig. 4) come into action, which push the exclusion wedges B from the guides Z onto the guides b ^x and move them along these until the exclusion wedges hit the guide pieces b ^{l due to the gravity} slide down. A guide ^{plate C "20} carries the front ends of the exclusion wedges in such a way that the wedges slide on this guide when they return to their initial position and do not clash with the new line that has been put together in the meantime. In the second paragraph the table / together with the oscillating frame L sinks back into the initial position shown in FIG. 1, in which the line now set to C is transferred to the table /.
