Definitions
- the invention relates to a collar transfer device
- a coilbox is one
- the metal collar which usually has a mass of about 10 to 40 t and a relatively high temperature, from about 900 ° C to 1100 ° C, take damage on its outer turn. A piece on the outer circumference is then scrap.
- the transfer of the metal collar takes place on support rollers whose
- Part-turn actuators, z. B a hydraulic cylinder. It creates a sequence of movements that resembles a "wandering wave” and moved the metal collar in a "wave trough".
- the metal collar is alternately supported by two or three support rollers.
- the federal government is supported in a first fret position by means of two arranged on a first frame part support rollers. The collar is moved out of this position by tilting and lowering this frame part at the same time. This is a smooth transition to the in the transport direction
- a stable position of the waistband can be achieved if the waistband is supported in alternating sequence by two or three idlers during the transfer. In order not to damage the surface of the belt, it is favorable if the peripheral speed of each in
- Figure 1 shows a metal collar, after winding in a winding position, wherein the unwinding process has already been started;
- Figure 2 is a representation of Figure 1 temporally following
- FIG. 3 shows a constellation temporally adjoining the representation of FIG. 2, in which the
- Metallbund was moved horizontally and is supported in the unwinding by two adjacent support rollers;
- Figure 4 is a representation of Figure 3 temporally following
- FIG. 5 shows the representation of FIG. 4
- FIG. 6 is a continuation of the scenario of FIG.
- Support roller is raised so that the metal collar is again supported by three support rollers;
- Figure 7 is a representation, at the end of the horizontal
- Transfer operation in which the metal collar is completely transferred to the unwinding position and is supported in this position again by two support rollers and by a retaining roller on a Rolling in the horizontal direction can be limited.
- FIG. 1 shows a metal collar 4, which is located in a winding-up position 5 of a coil box (not shown). This coil box is arranged between a roughing mill and a finishing mill of a rolling mill.
- Coilbox is used for winding and unwinding of the strip 2.
- the metal strip 2 coming from the roughing street can have a temperature of usually about 900-1100 ° C .; the fully wound metal collar 4 usually has a mass of about 10 to 40 t.
- the metal collar 4 is continuously unwound.
- the metal collar 4 rolls in each case with its outer turn at the bottom side arranged ground or support rollers 11, 12,13, 14, 15 from.
- the carrying rollers 11, 12 are arranged on a common frame part 29.
- the support rollers 13 and 14 each on an associated pivot arm.
- the two pivot arms point to Aufwickelposition 5. They are by means not shown Schenkantriebe each about an associated axis 27th
- FIG. 1 shows a constellation in which the winding is already completed.
- the band end 2 of the metal collar 4 is already unwound a bit.
- the tape head of the tape 2 is already supplied to a driver or a finishing mill, not shown.
- the metal collar 4 is in the winding position 5 shown in FIG. 1, no new pre-strip can be wound up in the coil box.
- the winding station in the coil box is occupied. It must therefore be released as soon as possible this Aufwickelplatz.
- the method according to the invention provides an approach for a gentle transfer of the metal bundle in the coil box.
- the collar transfer takes place by
- the two support rollers 11, 12 are mounted on a cross member of a first frame member 29 and rotationally driven.
- the first frame part 29 consists of a crosspiece and a longitudinal piece. The crosspiece and the longitudinal piece are rigidly interconnected. As shown in Figure 1 easy to
- the crosspiece and the longitudinal piece form the shape of a "T".
- the longitudinal piece of the first frame part 29 is articulated on the end to a second frame part 30.
- the first frame part 29 and the second frame part 30 together form the support frame 7.
- the support frame 7 functions as an angle lever: both the first frame part 29 and the second frame part 30 are each about an associated pivot axis 25
- Support frame 7 tilted and lowered at the same time. As can be seen from FIG. 2, this tilting and lowering movement takes place by the first frame part 29 being pivoted about the axis of rotation 25 in the direction of the arrow 18, and at the same time the second frame part being pivoted downwards in the direction of the arrow 17. Due to gravity and by the
- FIG. 5 now shows a scenario after a continuation of this principle.
- the lateral movement is supported by pivoting the first carrying roller 13 in the direction of the arrow 23.
- the unwinding trough 32 in FIG. 5 has moved to the left by a further distance.
- the first support roller 13 and the second support roller 14 support in this
- the first support roller 13 and the second support roller 14 are pivoted counterclockwise upwards, whereby the metal collar 4 is raised.
- the transfer of the metal collar 4 is completed.
- the metal collar 4 is now in the unwinding position 6.
- a roller 10 acts in this last movement section as a retaining role or support role and prevents the metal collar 4 due to the rigid arrangement of the support roller 15 too far in the direction of Driver rolls.
- the support or retaining roller 10 along the double arrow 9 in the horizontal direction is variable.
- the principle of moving a progressive floor sink has the advantage that the metal collar is constantly in a trough, that is in a stable position.
- the transfer of the metal collar 4 of support roller to support roller can be done comparatively gently by appropriate employment of the support rollers.
- each of the rollers 11, 12, 13, 14 is rotationally driven.
- the peripheral speed is set so that no slip occurs between the speed of the belt 2 and the rotational movement of the roller.
- the linear speed component resulting from the pivoting movement of the roller also becomes
