Definitions
- the invention relates to an extrusion press which has a block feed device for linear loading of a block to be pressed in an extruder with a frame comprising a linear guide rail and with a loading slide which is arranged linearly displaceable in the direction of a linear guide track on the linear guide device, wherein the loading slide a driver part for Includes holders of the block to be loaded.
- Such extruders in particular operated as a hydraulic extruder, with a pressing device for pressing a block to a semifinished product and with a block feeding device for loading the to be pressed, z. B. coming out of a furnace block in the extruder, where the block is then introduced by a block loader in a forming die preceded by a block receiver, are well known from the prior art, for example as a linear loader.
- linear loaders build very complex and they are therefore often very expensive in terms of their production and / or maintenance.
- generic block feed devices or linear loaders comprise a belt drive for driving a loading carriage along a linear guide rail.
- these belt drives are relatively susceptible to wear, which requires maintenance more frequently than desired.
- the invention has the object of further developing generic block feeders or linear loaders in order to overcome at least the aforementioned disadvantages at least partially.
- a block feed device for linear loading of a block to be pressed in an extruder with a frame comprising a linear ar Operationss worn and with a loading carriage, which is arranged linearly displaceable in the longitudinal direction of a linear guide rail on the linear guide device, wherein the loading carriage a Cartridge part for holding the block to be loaded, and wherein the block feeding device is characterized by a multi-part loading carriage with at least one relative to the linear guide linearly displaceable slide base and in addition with a linear with respect to both the linear guide device and relative to the carriage lower part linearly displaceable carriage upper part.
- the multipart loading carriage consisting of the carriage base and at least the carriage upper part can with a single functional component a additional distance to be generated with respect to a delivery route for loading the block to be loaded by the carriage upper part is extendable from the carriage base, or vice versa.
- the present block feed device has a loading carriage which can be extended in the longitudinal direction of the linear guide track and which has telescoping slide parts, namely the slide lower part and at least the slide upper part.
- the present loading carriage according to the invention has a variable basic length, which in the longitudinal direction of the linear guide track, if necessary, can be increased to support a delivery of a block to be loaded.

- the carriage upper part can be mounted displaceably on the slide lower part independently of a movement of the slide lower part, whereby both slide parts of the loading slide can be moved independently along the guide track.
- the carriage upper part can for this purpose have an independent drive, as well as the slide lower part.
- the Blockzu Bactuniques can be structurally simple to build when a transmission gear is arranged between the carriage upper part and a drive unit of the loading carriage. For example, by means of the drive unit of the loading carriage, the carriage upper part can be moved relative to the carriage lower part and about a linear guide rail, while the carriage lower part is displaced relative to this linear guide rail.
- Such a transmission gear can be constructed constructively varied.
- the carriage upper part relative to the slide lower part can be displaced by the same distance, as the slide lower part against especially the linear guide rail.
- other gear ratios can be selected, if this is advantageous for an application.

This eliminates the need to integrate the block feeder within auxiliaries of the extruder, which so far with regard to commissioning an increased installation effort is required. This is not applicable here.
