Definitions

• the invention relates to a descaling device comprising a housing, a shaft, a shaft bearing, a nozzle head, and a medium coupling.
• the shaft bearing is arranged in the housing, and the shaft is mounted in the housing by the bearing to enable rotation.
• the shaft and the nozzle head are connected to each other in a non-destructive manner.
• the medium coupling has a medium connection for supplying a medium, and the shaft has a cavity for guiding the medium supplied at the medium connection to the nozzle head.
• a scale washer typically consists of several such descaling devices.
• a scale washer also includes a high-pressure generating device. This device pressurizes a medium to approximately 200 to 420 bar. This medium is, for example, water.
• a scale washer is usually part of a hot forming machine, which shapes heated workpieces. Heating improves formability. Examples of such hot forming machines are hot rolling mills and forging presses. During hot forming, the temperature of a heated workpiece is often above its recrystallization temperature. The heat of the workpiece causes scale to form on its surface. Scale is an impurity consisting of iron oxide. Scale that forms immediately after heating a workpiece is particularly stubborn compared to scale that forms later and is called primary scale. Scale that is not removed from a workpiece is detrimental to that workpiece.
• a medium pressurized by the high-pressure generating device is fed into a descaling device at the medium connection of the medium coupling.
• the medium coupling directs the fed medium from the medium connection into the shaft cavity.
• the shaft cavity then directs the medium to the nozzle head.
• the nozzle head converts the pressure into kinetic energy and ejects the medium towards the workpiece.
• the kinetic energy of the medium causes the scale to be removed from the workpiece surface upon impact.
• the removal of scale from a surface is also known as descaling.
• the effectiveness of descaling depends on the velocity of the medium, and thus on the pressure of the medium, as well as the distance of the nozzle head from the workpiece. Therefore, the medium is pressurized to the highest possible level, and the nozzle head is positioned as close to the workpiece as possible.
• the nozzle head together with the shaft, performs the rotary motion determined by the shaft bearing.
• the shaft is driven by a motor, located separately from the descaling device, via additional drive components.
• a descaling device of the type described and also a scale washer are, for example, described in the patent specification.
• DE 43 28 303 C2 known.
• Further exemplary nozzle heads are from DE 92 16 438 U1 , US 3850 373 A or DE 10 2015 206393 A1 known.
• the object of the present invention is therefore to provide a descaling device of the type described, which reduces at least one of the described disadvantages.
• the descaling device of the described type has a motor which is arranged on the shaft in the device housing between the nozzle head and the medium coupling to generate the rotary motion of the shaft.
• This motor arrangement eliminates the need for additional drive components required to transmit rotary motion from a separately mounted motor to the shaft of a descaling device. This also eliminates the maintenance of these components, increases reliability, facilitates adaptability, and simplifies maintenance of the descaling device, particularly through improved accessibility due to the absence of these additional drive components. Furthermore, the descaling device is more compact than previously known descaling devices and enables a modular design for a descaling scrubber.
• the descaling device is arranged in close proximity to a hot workpiece in a hot forming machine. It is therefore exposed to the environmental influences of the hot forming machine. These environmental influences include, in particular, high temperatures, humidity, and particles such as removed, i.e., dissolved, scale. Therefore, in one embodiment of the descaling device according to the invention, the device housing hermetically encloses the motor. This hermetic enclosure of the motor ensures that that the motor itself is protected from environmental influences.
• the device housing is designed in such a way that no particles and preferably also not the descaling medium can penetrate it.
• the motor is designed as an electric motor.
• An electric motor generally comprises a motor shaft, a rotor mounted on the motor shaft, a motor housing, a stator located within the motor housing, and a bearing for supporting the motor shaft within the motor housing.
• the device housing also serves as the motor housing, the shaft also as the motor shaft, and the shaft bearing also as the motor shaft bearing.
• the stator is located within the device housing, and the rotor is mounted on the shaft.
• advantageous nozzle head speeds lie in the range of 500 rpm to 600 rpm. If alternating current with a frequency between 50 Hz and 60 Hz is available to supply the electric motor with electrical energy, an asynchronous motor with six pole pairs is particularly suitable.
• the shaft of an asynchronous motor with six pole pairs rotates at 500 rpm when powered by an alternating current of 50 Hz and at 600 rpm when powered by an alternating current of 60 Hz.
• the shaft is not made from a single workpiece, but comprises a first partial shaft and a second partial shaft, wherein the first partial shaft and the second partial shaft are connected to each other in a non-destructive manner.
• the shaft consists only of the first and second partial shafts.
• a first component, such as the first partial shaft, and a second component, such as the second partial shaft, are connected to each other in a non-destructive manner if, after the components are separated, they remain unchanged compared to their connected state. This also implies, in particular, that reconnecting the components is readily possible.
• a non-destructively detachable connection between the first and second partial shafts is implemented, for example, by a thread in the first partial shaft along a longitudinal axis of the first partial shaft and a thread complementary to this thread in the second partial shaft along a longitudinal axis of the second partial shaft.
• the first and second shaft sections can be easily and non-destructively connected by screwing them together and easily and non-destructively disconnected by loosening the screw connection.
• a sealing device is preferably also provided in the connection between the first and second shaft sections. This sealing device is, for example, at least one annular seal.
• this embodiment provides that the first shaft section is connected to the nozzle head, the shaft bearing is located exclusively on the first shaft section, and the medium coupling is located on the second shaft section.
• the medium coupling is located on the shaft, specifically on the second shaft section, thus creating a contact surface between the shaft and the medium coupling. Due to the rotational movement of the shaft within the medium coupling, both the shaft and the medium coupling wear at this contact surface. In this embodiment, when the wear on the shaft at the contact surface reaches a critical level, it is no longer necessary to replace the entire shaft, but only the second shaft section, without having to involve the shaft bearing.
• the first and second partial shafts each have a blind hole with an open end and a closed end.
• the blind hole of the first partial shaft and the blind hole of the second partial shaft together form the shaft cavity.
• the closed end of the first partial shaft is located at the nozzle head and the closed end of the second shaft is located at the medium coupling.
• the shaft is sealed at its ends by the closed ends of the blind holes.
• at least one end of the shaft is often sealed with a screw.
• sealing one end of a shaft with a screw is disadvantageous because, during operation of a descaling device, the injected medium exhibits strong pressure fluctuations, which exert a pulsating force on the screw in the longitudinal direction, causing the screw to loosen and allowing the medium to escape from the end of the shaft.
• the medium coupling comprises a coupling housing, a cover, and a sealing device.
• the coupling housing has a coupling cavity
• the cover which is detachably connected to the coupling housing without damage, closes the coupling cavity.
• the detachable connection between the cover and the coupling housing is implemented, for example, by a screw connection with at least one screw, the thread for which is formed in the coupling housing. To remove the cover, the At least one screw is unscrewed from the thread, and for assembly, at least one screw is screwed back into it.
• the sealing device is integrated into the coupling cavity to seal between the shaft and the medium connection.
• the sealing device thus ensures that any medium fed in at the medium connection is directed into the shaft cavity and does not, for example, leak between the shaft and the coupling housing.
• the medium coupling and the shaft are designed such that the sealing device can be removed and inserted when the cover is removed. This means that the sealing device can be pulled out of the shaft cavity and pushed into it, and conversely, it can be removed from the shaft and slid onto it.
• the design of the medium coupling relates in particular to the coupling housing and the sealing device.
• the design of the medium coupling and the shaft is such, for example, that both the coupling cavity and the shaft each have the shape of a vertical circular cylinder, and the sealing device is bounded by the outer shape of a hollow cylinder that is adapted to the coupling cavity and to the shaft within the coupling cavity.
• the sealing device consists of several sealing elements. This design thus allows for easy removal and insertion of the sealing device.
• the previously described contact surface between the shaft and the medium coupling is located between the shaft and the sealing device belonging to the medium coupling. Due to the rotational movement of the shaft within the sealing device, both the shaft and the sealing device wear down at the contact surface. In this design, the sealing device can be easily inspected after simple removal from the coupling housing. Furthermore, if the wear on the sealing device at the contact surface reaches a critical level, it can also be easily replaced.
• the coupling housing is separate from the device housing, and the coupling housing and the device housing are connected to each other in a non-destructively detachable manner.
• the non-destructively detachable connection between the coupling housing and the device housing is implemented, for example, by a screw connection with at least one screw, the thread for which is formed in the device housing.
• the at least one screw is unscrewed, and to assemble it, the at least one screw is screwed in.
• the shaft comprises a first partial shaft and a second partial shaft, and the medium coupling is arranged on the second partial shaft
• the coupling housing is designed and arranged on the device housing such that, with the coupling housing removed, the second partial shaft can be removed from the first partial shaft and mounted onto the first partial shaft.
• the second partial shaft is removable from the first partial shaft if the connection between the second partial shaft and the first partial shaft can be both disconnected and connected when the coupling housing is removed.
• the contact surface on the shaft can be advantageously inspected, and, if the wear on the shaft's contact surface reaches a critical level, the shaft can also be advantageously replaced.
• one embodiment of the descaling device incorporates cooling channels in the housing, and the housing is further designed to transfer the heat from the motor and/or radiant heat from the workpiece, particularly in front of the nozzle head, to a medium present in the cooling channels.
• cooling channels are formed in the part of the housing closest to the warm workpiece.
• another embodiment provides for the motor itself to transfer the heat generated during operation to a medium present in the shaft cavity. This design of the motor is achieved, for example, when its thermal conductivity is sufficiently high to ensure adequate heat transfer to the medium. This is often the case with an electric motor.
• the nozzle head of the descaling device is positioned as close as possible to the workpiece and ejects a descaling medium onto the scale-covered surface of the workpiece. This causes the scale to be blasted off the workpiece surface and also strike the nozzle head, which is subject to wear from the impact of the scale. Therefore, in a further embodiment, the nozzle head is provided with a nozzle head carrier and a nozzle holder.
• the nozzle holder contains at least one A nozzle is arranged for ejecting a medium, and at least one channel is formed in the nozzle head carrier for guiding the medium from the shaft cavity to the at least one nozzle.
• the nozzle carrier and the nozzle head carrier are connected to each other in a non-destructively detachable manner, and the nozzle head carrier and the shaft are connected to each other. Accordingly, the nozzle carrier is positioned in front of the nozzle head carrier with respect to the workpiece, and the nozzle carrier is subject to wear from scale.
• the non-destructively detachable connection between the nozzle head and the nozzle head carrier is implemented, for example, by a screw connection with at least one screw, the thread for which is formed in the nozzle head carrier. To remove the nozzle head, the at least one screw is unscrewed, and to install it, the at least one screw is screwed in. With this embodiment, it is no longer necessary to replace the entire nozzle head when a critical level of wear is reached; instead, replacing only the nozzle carrier is sufficient.
