A METHOD FOR STRAIGHTENING OF A FECRAL ALLOY TUBE

Abstract

The present disclosure relates to a method for straightening of a tube comprising a ferritic FeCrAI-alloy. One reason for the challenges regarding the cold working of a hollow of a ferritic FeCrAI-alloy into a finished tube is that FeCrAI-alloys have a low ductility. Even if a tube of a FeCrAI-alloy is obtained by cold working a hollow into a tube, the tube can hardly be straightened. This is even more a problem if a tube obtained is annealed, wherein the annealing leads to a deformation of tube along the longitudinal direction of the tube. Therefore, there is a need for a method for straightening of a tube comprising a ferritic FeCrAI-alloy. Thus, according to the present disclosure a method for straightening of a tube is suggested, wherein the method comprises the steps of providing a tube comprising a ferritic FeCrAI-alloy, heating the tube, and straightening and forming the heated tube by stretching.

Abstract

The present disclosure relates to a screening media (1) for a vibratory separator wherein said media comprises of two or more layers of rubber, wherein the layer (10) below the top layer (8) is reinforced with fabric thereby rendering the media more durable. As a result the screening media shows better hole tolerance and increased hole capacity in comparison to its predecessors. Additionally, the fabric-reinforced layer acts as a wear-indicator for the operator of the assembly, since the fabric has a color different from the color of the rubber. When the top rubber layer (8) gets torn due to excessive wear, the fabric-reinforced layer is exposed which serves as an indication for the operator to replace the screen. The screening media is lighter, capable of being rolled into a mat, easy to transport and install, and cost-effective to produce when compared to the screening media used currently in the industry. The rubber screening media described in the present disclosure is manufactured using rotating drum vulcanization process.

Deflection of the cutting edge is estimated based on output from the strain gauge and the accelerometer. In some embodiments, the accelerometer is arranged close to the cutting edge while the strain gauge is arranged where the tool bar is susceptible to the largest strain. In some embodiments, low frequency vibrations of the cutting edge are estimated based measured strain, high frequency vibrations are estimated based on measured acceleration, and medium frequency vibrations are estimated based on output from both sensor types.

Abstract

A computer program (102) includes data defining tool paths for manufacturing a component (108). The component geometry is estimated (403) based on the program. Deviation of a first type is estimated (404) as deviation between the estimated geometry and geometry of the component as defined by a 3D model (102). Deviation of a second type is estimated (409), based on machining process characteristics indicated by sensor data (301) captured during manufacturing (213) of the component, as deviation between a tool path a machine (107) is instructed via the program to provide and an actual tool path provided by the machine. Deviation of a third type is computed (410) as deviation between geometry defined by the 3D model and measured geometry of the manufactured component. An error propagation model is updated (411) based on the estimated and computed deviations for multiple components. The error propagation model approximates relations between deviations of the first and second type and deviations of the third type.

Abstract

A rotor positioning device (113) in a crusher (1) for adjusting a rotational position of a rotor shaft (6). A shaft engager (105) includes a female toothed mating surface (120) for coaxial engagement with a male mating surface (121) at an end of the rotor shaft (6), so they become rotationally interlocked. The shaft engager (105) includes alignable indicator slots (128) that are, in use, alignable with markings (129) associated with an end of the rotor shaft (6), such that said markings become visible through the slots (128) as the rod (104) is rotationally driven by a drive component (107, 108). The markings (129) correspond to hammer positions within the crusher, such that these can be manoeuvred for maintenance (e.g. to top dead-centre positions) before access to the crusher chamber is gained.

Abstract

A rotor locking device (113) in a crusher (1) for locking a rotational position of a rotor shaft (6). A shaft engager (105) includes a female toothed mating surface (120) for coaxial engagement with a male mating surface (121) at an end of the rotor shaft (6), so they become rotationally interlocked. A fastening portion (122) with engager apertures (123) overlaps with a bearing mount (200) surrounding the rotor shaft (6) so it can be fastened therewith. Preferably, the engager apertures (123) are circumferentially elongated in order to accommodate alignment with fastening points (205) in the bearing mount (200), at least when a closest rotational mating position is chosen for alignment. This enables any rotational position of the rotor shaft (6) to be locked, for safety, before having to access the crusher chamber. This safety feature is desirable when the rotor of the crusher (1) has become blocked and requires maintenance.
