Description

Horizontal metal extrusion press

CO CO O

The invention relates to a horizontal metal extrusion press with tie rods and with at least one rotatable holder, the carries at least three auxiliary pressing tools and around one to the main pressing axis parallel axis is rotatable in order to prevent each of the tools successively through several work or rest positions.

In a known horizontal extrusion press of this type, which is equipped with niLi, two such rotatable holders, their fall Rotary axes together with de.i axes of two tie rods arranged one above the other. However, this leads to a considerable amount of the Press, as this is determined by the distance that the top Liuheste llung for the auxiliary pressing tools of the upper holder of the lower rest position for the auxiliary tools of the lower one

■ has rotatable holder. This amount usually amounts to several meters. Auxiliary devices, such as conveyor drives, at the rest positions are therefore difficult to access.

The invention is based on the object, the amount of Significantly reduce the extrusion press.

This object is achieved according to the invention in that the Dreiisclise fles holder in the middle between two perpendicular in the Distance one above the other arranged tie rods and that two rest positions of the holder are located one above the other, namely the upper rest position below the axis of the upper Zugaukors the horizontal plane and the lower rest position above the horizontal one that receives the axis of the lower tie rod Level. The two rest positions are therefore one above the other In the space between the horizontal planes, which take up the .Aohffeß of the © "regret and the lower tie rod the result is a compact arrangement and easy accessibility of the press parts to be operated.

The upper rest position is preferably that position in which the residue is ejected, while the lower rest position is the one at which the press is loaded with a block will.

If it is a press with four tie rods, then Such an arrangement of two rotatable holders is recommended, one of which is block pick-up and the other of which dies carries that the axes of rotation of the holder in i) urchuiossürricht> ung facing each other with respect to the Hauptpredsenacb.se and in the same horizontal plane as d.i. eau presses—

The holder for the dies can also carry two punches for separating the press residue and the dies and the Punches can have equally large angular distances.

Further objects of the invention emerge from the following description of an exemplary embodiment of the invention with reference to the drawings. Ln these show:

fr'ig. 3 a schematic representation of the distribution of the various processes about the jobs in a trust & preü work game.

Like the fc'ig. 1 and 2 show, the metal extrusion press according to the invention has a hydraulic main cylinder 10 with a main piston 11 displaceable therein and one with the main cylinder through four in i ^fl ig. 2, columns 13 to Ib connected to the counter-holder 12, not shown. A Preüsterapel 17 is attached to the main piston 11, through which a mandrel 18 protrudes, which is used for pressing hollow products, for example for pressing pipes. The main working axis XX of the press is that "', along which the ram 17 and the mandrel Id are advanced at iiiimm bfrangpreßvorgaug.

Furthermore, one of the three nufnelimer 19, 119 and 219 and one of the two die units 20 and 12ü are arranged in the axis 3L-X Pin 22 is rotatable. The drive for rotating this jester or turret is not illustrated. Lr can be designed in any way, for example as an electric motor provided with an overdrive gear. The three transducers i9, ii ) and 219 are located on a circle and the axis of the journal 22, this circle running at the point P in FIG. 1 through the main working axis XX of the press. The three sensors 19, 119 and 219 are located on this circle at an angular distance of 120, so that with each step-by-step rotation of the holder 21 through this angle the next sensor reaches each of the three workplaces λ, B and G, which are also in one Distance from 120 to each other are arranged (Tig. L). The job A is located in the press axis XX and accordingly represents the pressing position. The jobs B and G, however, are outside the actual press. In the illustrated embodiment, one overlies the other. For the sake of simplicity, the three sensors 19, 119 and 219 are shown in FIG. 2 in such a way that they are located in a common plane.

The two die units 2ü and i £ ü are connected to a common holder or llevolverkopi 2Ί with two Hilis devices, e.g. punches 23 and 123 for separating the press restos.

There is also the possibility of separating the press residue to be carried out by means of one of the punching tools 23 or 123.

At the work station B, the PrcPrest 35 with the press disk 36 are simultaneously ejected from the receptacle 219 by means of the ejection tool Jk , and the receptacle is then cleaned by the tool 36.

The loading of the pick-up 19 takes place at the work station Ό , while the work explained at the work stations A and B takes place at the same time. It is therefore possible to carry out several auxiliary work at the same time with the press according to the invention, while the extrusion process is carried out at another work station. In this way, the time required to carry out an extrusion work cycle can be shortened considerably and the output of the press can be increased accordingly. One must take this connection into account that the

time required for the actual extrusion process only a small fraction of the time taken up by the entire work game. This is especially true for the erosion of such metals as iron, which are pressed at high speed and, on the other hand, before and after each pressing process require a greater number of KiIfsarbeit.

The press according to the invention can have more than three sensors be provided and accordingly also ineJar as two have workplaces located outside the tier press. Of course, the number of transducers must match the total number of jobs correspond including those arranged inside and outside the press. Are outside the press If more than two work stations are provided, one can load the sensor with the block and the ram take place while the press residue and the press disk are ejected at the second work station and at the third Work place the cleaning of the transducer takes place. Thereby iaßi, sicii the x'tir the entire work cycle required nof;, shorten i further.
