Definitions

  • the invention relates to an extrusion machine for the continuous production of profiles from a formable extruded material.
  • a generic extrusion machine is known from the WO 2015/070274 A1
  • the extrusion machine is used for the continuous production of profiles from a formable extrusion and comprises a base frame, a friction wheel that can be rotated about a drive axis, a tool holder, a locking device and a tool unit supported on the tool holder.
  • the tool holder is mounted on a pivot axis held on the base frame and can be pivoted between a working position and a release position.
  • the locking device holds the tool holder in its working position.
  • the tool unit is also accommodated in a receiving chamber arranged in the tool holder and comprises a stripping element arranged in a stripping area.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide an extrusion machine and a method by means of which a user is able to ensure safe and economical operation of the extrusion machine In addition to this, or independently of this, a higher quality of the manufactured profile should also be achievable. Furthermore, the friction wheel change should be made easier and less dangerous for the operator.
  • the advantage achieved by this is that by providing an additional shielding unit within the extrusion machine in the area in which the extruded material to be formed is heated to the required forming temperature by means of the friction wheel, the ingress of oxygen, such as that present in the ambient air, can be minimized or completely prevented.
  • a gas free of gaseous oxygen can be supplied in order to create an oxygen-poor or oxygen-free atmosphere in this area or machine section. This means that the high initial quality of the still undeformed extruded material can be retained entirely or at least to a very high percentage in the manufactured profile. This means that oxygen absorption can be greatly minimized or completely prevented, particularly in an outer edge area of the profile, and an even higher quality can be achieved in the production of the profiles.
  • At least one of the nozzles is arranged or formed on the tool unit. If at least one of the nozzles is arranged on the tool unit, a reliable shielding effect can be achieved in the area with the highest material temperature. Furthermore, the supply and feeding of the nozzles with the gas, in particular its piping, can also be simplified via the tool unit and the tool holding device.
  • the shielding unit further comprises at least one shut-off flap, and the at least one shut-off flap of the at least one first nozzle is arranged upstream of the first nozzle in the region of the circumferential section of the friction wheel and in the direction of rotation of the friction wheel.
  • the shielding unit comprises a further nozzle arrangement, which further nozzle arrangement is arranged downstream of the at least one second nozzle as seen in the direction of rotation of the friction wheel. This makes it possible to create an additional blocking effect in the area following the stripping area in the direction of rotation of the friction wheel. This makes it possible to provide an additional barrier curtain against the ingress of oxygen.
  • the advantage achieved by this is that by providing the sensor unit for detecting a force transmitted from the tool unit to the tool holding device, Compressive force and, with prior knowledge of the forming force normally required, a conclusion can be drawn so that errors or overloads that occur when there are changes or deviations from this can be quickly identified. This can prevent damage to the extrusion machine, for example, if the forming force increases and the resulting higher measured compressive force.
  • the required or existing forming force can be recorded as compressive force by the sensor unit and stored as a target value for each profile geometry with upper and lower limits. If, for example, the upper limit is exceeded, the speed of the friction wheel can be reduced in order to carry out proper forming operations within the specified limits without causing damage to the machine.
  • the first sensor unit comprises several, in particular four, sensors which are arranged in a peripheral edge region of the tool unit. If several sensors are provided to form the first sensor unit, this can enable more uniform support and pressure determination from the tool unit to the tool holding device.
  • the first sensor unit is connected to a control and/or regulating device for communication purposes. This allows the currently measured and determined forming forces and/or pressure forces of the tool unit to be compared with predetermined forces within certain limits and, if these are exceeded or not met, operating parameters such as the speed of the friction wheel, the feed speed of the extruded material, etc., can be adjusted in order to ensure proper operation of the extrusion machine.
  • Another embodiment is characterized in that at least one tempering element is provided, which is accommodated in the receiving chamber and is arranged in front of the sensor unit in the direction of the friction wheel, wherein the at least one tempering element is designed to dissipate heat from the tool unit. This allows heat to be transferred from the tool unit to the sensor unit. can be minimized or reduced. Furthermore, the prevailing temperature in the area of the sensor unit can be kept constant within certain limits in order to achieve more precise measurement results.
  • a further preferred embodiment is characterized in that the at least one tempering element forms a component of the tool unit. This allows a compact design of the tool unit to be created.
  • a base distance value can be determined, which serves as a reference for temperature-related changes in the length of the first tool component. Due to the temperature-related change in dimensions, namely an increase in the same, further distance values are subsequently determined during the ongoing forming operation in order to draw conclusions about the actual dimensions of this tool component. Furthermore, if the base gap width is set in an initial state in which the extrusion machine and the tool components have a low temperature, in particular ambient temperature, the gap width can be readjusted during the ongoing forming operation based on the determined actual value of the gap width. This can prevent or avoid collisions between tool components of the extrusion machine that are moving relative to one another.
  • the initial determination or setting of the first gap value can also be referred to as the calibration step in order to form a reference basis for the subsequent steps or process features.
  • the adjustment and setting of the gap width can also be referred to as the adjustment step.
  • a procedure is advantageous in which the determination of the first distance value is carried out at an initial temperature of the first tool component in a temperature range between 10°C and 40°C. This ensures that the first tool component in its "cold state" has the usual dimensions without any temperature-related change in length.
  • a further advantageous procedure is characterized in that the first tool component is formed by a friction wheel of the extrusion machine.
  • the first tool component is thus defined as a rotating component, which serves to introduce the necessary forming temperature into the extruded material to be formed.
  • a method variant is also advantageous in which the second tool component is formed by a tool unit received in a tool holding device and held in position in the tool holding device with at least one stripping element facing the first tool component, in particular the friction wheel. This allows a clear relationship to be established between the two tool components for the gap adjustment.
  • tool units being designed or being designed with the same longitudinal dimension in their longitudinal extension, starting from the stripping element up to a tool end surface arranged at a distance from it in the direction of passage of the manufactured profile.
  • Another advantageous approach is one in which the tool holding device is pivotally mounted about a pivot axis held on a base frame and can be pivoted between a working position and a release position. This makes it easy to change tools in the release position.
  • a further advantageous procedure is characterized in that when the second tool component, in particular the tool unit, is in abutting position on the first tool component, in particular the friction wheel, a base angle position of the tool holding device with respect to the base frame is determined and stored in the control and/or regulating device. This allows a relative constantly recurring base position of the Tool holding device can be determined in relation to the base frame and used as a reference basis for subsequent adjustment and alignment processes.
  • Another advantageous variant of the method is one in which, after the second tool component, in particular the tool unit, has been moved away from the first tool component, in particular the friction wheel, a target angular position is determined and stored in the control and/or regulating device. This means that the predetermined angular position of the still "cold" extrusion machine can be determined and recorded before the extrusion machine is put into operation for the forming process.
  • Another procedure is characterized by the fact that after a tool change of the second tool component, in particular the tool unit, has been carried out and when the first tool component, in particular the friction wheel, is at a standstill, the tool holding device together with the second tool component is pivoted from its release position towards the working position until the relative base angular position between the tool holding device and the base frame is reached and the second tool component, in particular the tool unit, is brought into contact with the first tool component, in particular the friction wheel.
  • This makes it possible to control and check whether or not the specified base angular position has been reached when the second tool component is mechanically in contact with the first tool component.
  • a procedure is advantageous in which an error handling routine is started by the control and regulating device when the second tool component, in particular the tool unit, is placed on the first tool component, in particular the friction wheel, before the relative base angular position between the tool holding device and the base frame is reached. This can prevent damage to the machine, which can be quickly and easily identified by an otherwise incorrect positioning of the second tool component in the tool holding device and can be remedied and eliminated before commissioning.
  • a further advantageous procedure is characterized in that the second tool component is formed by a scraping device with a scraper element. It becomes possible to align and adjust the position of another tool component in relation to the first tool component. In this example, this concerns the scraping device with its scraper element.
  • a variant of the method is also advantageous in which the scraper element is placed against the first tool component, in particular against the friction wheel, when approaching and feeding in the direction of the first tool component. This also allows positioning of the scraper element alone and thus the gap setting to be carried out precisely.
  • the advantage of this embodiment of the extrusion machine is that the accessibility to the friction wheel to be changed can be significantly improved, since the entire first bearing device, including the drive wheel, can be adjusted from the working position inside the base frame to a change position outside the base frame.
  • the first bearing device is completely pulled off the drive shaft, whereby the friction wheel is also pulled off the drive shaft and arranged at a distance.
  • a separate arm, in particular an extension arm, with a guide arrangement is provided, which serves to hold the first bearing device during the relative adjustment movement.
  • the coupling device it is possible to keep the entire first bearing device in a fixed position on the base frame.
  • a structural unit of the base frame with the drive unit and the bearing unit, in particular the displaceable first bearing device can be created in the operating state.
  • the first bearing device together with the friction wheel can be made easier for the operating personnel, even with larger and heavier friction wheels, possibly including the drive rings. This can also reduce the risk of accidents and increase user-friendliness. Furthermore, it can also enable and carry out a faster friction wheel change.
  • the second bearing device together with the drive shaft is arranged in a fixed position on the base frame. This enables the drive shaft to be mounted on the base frame in a floating manner during the friction wheel changing process, in which nevertheless, sufficient bearing of the drive shaft is still maintained even during the friction wheel change process.
  • Another embodiment is characterized in that the at least one cantilever arm extends from the base frame to the side facing away from the drive device. This allows a simple and collision-free adjustment of the path of the first bearing device. Furthermore, an unhindered arrangement of the drive device is also possible.
  • Another possible embodiment has the features that the at least one boom arm is arranged vertically above the drive shaft and the first bearing device is held in a suspended arrangement on at least one boom arm or that one boom arm is arranged below the drive shaft and the first bearing device is supported on at least one boom arm.
  • This can further improve accessibility for carrying out the friction wheel change to the relocated and decoupled first bearing device.
  • This also allows sufficient free space to be created in the floor area using aids such as mobile transport devices, lifting devices or the like.
  • the boom arm is arranged on the floor, it is easier to support it directly on the contact surface for the system.
  • a further preferred embodiment is characterized in that the at least one extension arm is held on the base frame. This enables a more precise alignment and positioning of the drive shaft and the first bearing device relative to one another for carrying out the friction wheel changing process.
  • a further embodiment provides that at least one friction wheel is held on the first bearing device, possibly with the interposition of a drive ring. This allows a joint path adjustment of the friction wheel together with the first bearing device to be carried out by the base frame.
  • a further possible embodiment has the features that a support arrangement is provided and the support arrangement comprises at least one support device which at least a support device is or are arranged on at least one side facing away from the friction wheel, preferably on both sides facing away from the friction wheel, of the bearing devices on the drive shaft in a form-fitting manner in the axial direction.
  • the support device comprises at least two support elements and the at least two support elements are arranged on the outside of the drive shaft.
  • the split design of the support device enables a secure and, above all, space-saving arrangement on the drive shaft and easy removal and disassembly.
  • the support elements are preferably designed as half shells and thus surround the drive shaft.
  • first recesses are provided in the drive shaft, spaced apart from one another in the axial direction, and a first support flange is formed between each of the first recesses that are immediately adjacent in the axial direction, and the support elements have second recesses that are designed in opposite directions, and a second support flange is formed between each of the second recesses that are immediately adjacent in the axial direction.
  • the recesses in the form of an annular groove can thus be designed and arranged very precisely on the drive shaft.
  • the support elements which are designed in opposite directions, engage with their second support flanges in the first recesses in the drive shaft. This allows very precise and almost play-free engagement and, associated with this, uniform power transmission.
  • the advantage of this procedure is that the accessibility to the friction wheel to be changed can be significantly improved, since the entire first bearing device and also the drive wheel can be adjusted from the working position inside the base frame to a change position outside the base frame.
  • the first bearing device can be completely pulled off the drive shaft, whereby the friction wheel is also pulled off the drive shaft and arranged at a distance.

  • This also allows sufficient space to be created in the floor area using aids such as mobile transport devices, lifting devices or the like.
  • the arrangement of the boom arm on the floor makes it easier to support the system directly on the contact surface.
  • the advantage of this embodiment of the extrusion machine is that the entire first bearing device does not have to be moved away from the base frame, but the two bearing devices can remain on the base frame for the friction wheel change.
  • the support elements are preferably designed as half shells and thus surround the drive shaft. This means that after the support device has been removed, the drive shaft can be released from its coupling connection to the drive unit without any further significant rotational movement and can be pulled out of the second bearing device in the axial direction until the friction wheel is released.
  • An advantageous possible embodiment is characterized in that several groove-shaped first recesses are provided in the drive shaft, arranged at a distance from one another in the axial direction, and a first support flange is formed between each of the first recesses that are immediately adjacent in the axial direction, and that the support elements have second recesses that are formed in opposite directions, and a second support flange is formed between each of the second recesses that are immediately adjacent in the axial direction.
