Metal extrusion and pipe press

The invention relates to a metal extrusion and pipe press, their press parts for the aligned position of the mandrel, block pick-up and die in longitudinal slide ways are led.

Means and devices are required to bring the mandrel, die and block picker into a precisely aligned position known, the partially rigid or adjustable guides or special adjustment devices for the Concern housings that carry the ram or mandrel, die or block pick-up.

In a known press of this type, for example, the block pick-up carried and guided in longitudinal slideways is known and counter bar to be arranged in the press base frame so that it can be adjusted transversely to the press axis. For this purpose, eccentrics that can be rotated about vertical bearings are provided, the plates guided in separate slideways push through.

By turning the eccentric pin using a tool a laterally horizontal shifting of the guided plates can be achieved, whereby the aligned The position of the die and the receiver in relation to the mandrel is to be established

The misaligned position of these press parts can

various causes during the press operation.

So are different stresses by effective forces, including uneven expansion as a result The influence of heat is often the reason for a misaligned position.

The aim is therefore not only to always keep all the relevant press parts in alignment with one another set by special devices, but to force them constantly.

This problem is dealt with in the problem on which the invention is based. Sine little tree filling »easy to manufacture, hardly maintenance-required lateral forced guidance, which is used for long-stroke press parts such as sliding crossbeams and The subject of the invention is block pick-up, which is ideally suited and insensitive to thermal expansion.

The task is solved by a fixed, narrow one in the middle of the press, from the cylinder spar to Beam extending to the opposing spar, on which the sliding crossbeam, the block pick-up and the opposing spar are laterally guided in the longitudinal direction by sliding pieces arranged on both sides of the carrier.

A pair of sliding pieces is assigned to each of the sliding crossbars, the block pick-up and the counter-member attached to them in an articulated and adjustable manner.

The rigid, centrally arranged guide beam ensures a relatively simple, precise and yet not very complex management of the decisive factor in the Press parts involved in the aligned position in the direction of the press axis.

Although the carrier Terhältnlsmaßig is kept narrow, it is, due to its solid construction, especially against _{Warneausdehrmngsgefahr:..} An insensitive guide element.

In addition, occurring forces are to a large extent by added to the guide element. This is particularly important for panel frame constructions.

The sliding pieces arranged to the left and right of the carrier are preferably in the Eugelpfannen of the transducer or The counter bar and the sliding cross-member are stored, thereby ensuring the best possible adjustability to the guide beam is achieved.

In the drawing, an embodiment of the metal extrusion and drilling press according to the invention is shown.

Counter beam 4, block pick-up 7 and sliding cross-member 8 are each provided with claw-like extensions 9 which surround the guide support 6 in the area of the guide surfaces 11
