Definitions
- the invention relates to a method for rolling pipes in tube sheets of the type mentioned in the preamble of claim 1 above.
- a method of this type is known from DE-A 2 331 341.
- the rolling mandrel which is engaged with axially parallel rolling rollers, is displaced in the direction of the rolling rollers until the required adhesive expansion is achieved.
- the adhesion expansion is measured as the torque occurring at the drive motor and when the set torque corresponding to the desired adhesion expansion is reached, at least the mandrel feed is switched off by the drive machine.
- This object is achieved in that the size of the adhesion expansion is determined by means of an ultrasound measurement of the changing thickness of the tube wall during the expansion.
- the invention also relates to a device for carrying out the method and is based on a device according to DE-A 2 331 341 with a tube roller driven by a drive machine and a rolling-in control device on which the desired adhesion expansion value can be set.
- an ultrasonic measuring head is provided in the tube roll, which is connected to the roll-in control device.
- the measuring arrangement it is primarily important that an ultrasonic field component penetrates into the tube wall.
- Mirror arrangements can be interposed.
- the ultrasound head is preferably arranged substantially perpendicular to the axis of rotation of the tube roller.
- the device is based on a tube roller as described in DE-A 2 331 341.
- a tube roll has at least several roll rolls arranged axially parallel in a rotatable roll body and an at least axially advanceable conical roll mandrel for the spreading of the roll roll.
- the ultrasonic measuring head is expediently arranged in the roller body.
- the ultrasonic measuring head is connected to the roll-in control device via a slip ring connection.
- the space between the measuring window and the inner tube wall is filled with a liquid.
- this liquid can also dissipate the heat released during the rolling in if the annular space is not only filled statically with the coupling liquid, preferably water, but is flowed through by it.
- the method according to the invention enables Feed and rotation are rigidly coupled with each other because the wall thickness is measured directly. There is therefore no need for a separate coupling between the advance movement and the rotary movement.
- the rotational movement of the rolling mandrel is transmitted to the rolling body via the rolling rollers. It is therefore preferable that the rolling mandrel and the rolling body are in rotational engagement with one another via the rolling rollers without a clutch.
- the tubular roller 1 has a basic component 2, in which a roller body 3 is rotatably mounted via bearings 4 and 5.
- roller body 3 In the roller body 3, three roller rollers 6 are mounted axially parallel in corresponding slots 3a of the roller body.
- a rolling mandrel 7, which extends conically towards the front, is displaceably arranged, by means of which the rolling rollers 6 can be spread.
- the geometry of the rolling rollers 6 is adapted to the conicity of the rolling mandrel 7.
- the rolling mandrel 7 is connected to a drive 8 which can advance and rotate the rolling mandrel 7.
- the arrangement of the roller rollers 6 in the slots 3a and the placement of the roller rollers on the surface of the mandrel 7 transmit a rotary movement to the roller body 3.
- An ultrasonic measuring head 9 is arranged in the roller body between the slits 3a formed at 120 ° , the measuring window 9a of which is aligned radially with the inner wall IW of a tube R to be rolled into a tube sheet RB.
- the ultrasonic measuring head 9 is connected to a slip ring device 11 via lines 10.
- the grinding device 11 in the basic component 1 is connected via line 12 to a rolling-in controller 13, to which the adhesion expansion value to be achieved is predetermined via a setpoint adjuster 13a.
- the rolling-in control device can control a switch 14, which in turn can switch the drive on or off.
- the expansion process can be logged using a display and / or writing device 15.
- the basic component 2 is provided with a water connection 2a, so that the annular space between the mandrel 7 and the roller body 3 can be filled with water, which exits via the slots 3a and also fills the annular space between the outer surface of the roller body and the inner wall IW of the tube.
- sealing measures are required, two of which ring seals 16 and 17 are shown in FIG. 1.
- the person skilled in the art is readily able to provide appropriate seals, such as, B. seal 18 to provide. For the sake of simplicity, these are not all shown.
- the application of water can take place statically, so that there is no through-flow, or else flowing, so that the heat generated during rolling can also be dissipated by means of the coupling liquid.
- the impulses attributable to the impingement of the ultrasonic field on the inner tube wall IW and on the tube sheet RB can be discriminated from one another, so that a continuous thickness measurement is possible.
- Ultrasonic measuring methods for determining thickness are known per se.
