Definitions
- the invention relates to a method for separating partial lengths in Extrusion of rounded or curved metallic extruded products, wherein the Preßauer in a counter-spar of an extrusion press upstream Mold formed and then curved by the action of external forces or is bent.
- the invention is based on the object, a method of the type mentioned to create, with which desired without detriment to the extrusion product Separate part lengths.
- the Extruded product is cut to length by flame cutting.
- This can be advantageous a burner medium made of different gas compositions and Use mixing ratios. Suitable are the usual gases, such as oxygen, acetylene, propane, butane, natural gas, etc. and their mixtures.
- a preferred further proposal provides that the squeezed product in Production flow is cut to length by plasma cutting.
- join in realize the said burner inserts short cycle times when disconnecting what It allows a defined material condition and the economy of the Extrusion (extrusion rate) to adjust accordingly.
- the burner head - or the burner heads - as close as possible to the Extrusion product can be with regard to the separation time and the Quality of the cut to achieve optimized efficiency. It lies here in the context of the method according to the invention, the burner head depending on Component profile from the outset so adapt or interpret that a nationwide admission over the entire profile is guaranteed.
- Another proposal of the invention provides that the - in the starting position behind the rounding tool arranged - burner head during the separation process of a Robot according to the current radius of curvature of the extruded product is positioned.
- the already existing from an extruder on an extrusion line higher-level computer-controlled robot also allows that at high Extrusion speeds and large extrusion cross sections of the robot Burner head in the extrusion direction leads to the profile thus at a defined Place to separate.
- the combustion head is mounted on a linear axis - e.g. disposed on the rounding tool - guided and impinged with gas.
- the Jerky gas supply assists that the profile in no time is disconnected.
- the Passing a mark by a control loop an impulse on the Burner unit is triggered. Immediately upon reaching the mark becomes so, e.g. caused pneumatically, the profile applied to the separation medium.
