Abstract
Flying shears for thin hot strip are to be configured in such a way tha t very fast running strip con be securely cut. For the purpose it is proposed that one of the cutting tool drums of mounted on a rocker, that an adjusting device consists of drives effecting the cutting movement and support elements located between said drives and the rockers and that the support elements are shortenable to an effective position effecting a cut.
Description
High-speed shears for cutting rolled strip to length The invention relates to flying shears with cutting tools located on drums facing each other, which tools are accelerable by at least one driving device assigned to them to a peripheral speed corresponding to the speed of the strip to be cut and with separately controllable adjusting device assigned to one of the drums.
Similar shears have become known through DIE-OS 21 38 478. These shears are, however, intended for the cutting of fast-running wire. For the cutting of strips, DE-OS 41 28 970 discloses linear guides for the drums, which guides are located in stands. In this case, blades are used, which require very exact synchronization between drum drive and adjusting drive in order to be able to execute a correspondingly clean cut. Through this very e:Kact synchronization, such shears are relatively slow.
The invention is based on the object of further developing flying shears for the cutting of hot strip in such a way that good cutting resullrs are guaranteed even at strip speeds of up to 30 m/sec and with minimal strip thicknesses.
For the solving of this object it is proposed that one of the drums is mounted on rockers, that the adjusting device consists of drives effecting the cutting movement and support elements located between said drives and the rockers and that the support elements are shortenable to an effective position effecting a cut. A
further solution proposal consists in that one of the drums is mounted on rockers, that the rockers are supported by means of support elements, that the support elements are shortenable to an effective position effecting a cut, that the adjusting device has cranks which are connected with the second drum, and said second drum is capable of leading to the cut through paraxial displacement towards the first drum.
Through this design of the shears it is achieved that the drums can always be driven at a peripheral speed corresponding to the speed of the strip to be cut or at a peripheral speed slightly lowered in comparison with said speed respectively.
Thereby the cutting tools can always execute the cutting movement without a cut being made. Only when a cut is to be executed are the support elements brought into effective postion. The next cutting movement of the cutting tools then leads to the cut.
There is also the possibility to leave only the drums constantly at a corresponding peripheral speed and to drive the adjusting device only for a cut.
Alternatively the driving device for the drums can naturally also be brought to a standstill during the times in which no cut is to be made. In order to accelerate these drums for the cut, however, substantially greater motor outputs are required than if the drums were to run constantly at a corresponding peripheral speed.
It is of advantage if the support elements are lockable in their effective length. By this means it is achieved that a spring-back between the drums is limited to a minimum so that cuts as exact as possible can be made. 1I\lith corresponding dimensioning of the support elements, the power transmission can be effected directly by them, i.e.
without corresponding locking.
Through the use of chisel and anvil as cutting i:ools, a very exact synchronization, as is required with cutting blades, is not necessary. Nonetheless, a synchronization between the driving devices and the drives or cranks respectively is appropriate, whereby, however, slight slips can be compensated through the fact that larger jacket areas act as an anvil.
It is advisable to bring the support elements into their effective position before the beginning of the working stroke of the drives or cranks respectively. By this means it is guaranteed that the support elements are already in effective position during the cut and irregularities cannot occur through adjustments of the support elements during the cut.
In the case of the very thin hot strips to be cut here, it has been shown that the strip starts are very difficult to guide after a cut. It is therefore of great importance to integrate the cutting devices into a corresponding coiler or to place said cutting devices at a minimum distance in front of the coiler respectively.
In one aspect, the present invention resides in flying shears with cutting tools located on respective first and second drums arranged facing each other, which tools are accelerable by at least one driving device associated therewith to a peripheral speed corresponding to a speed of a strip to be cut wherein the second drum is mounted on rockers associated with a separately controllable adjusting device consisting of drives effecting the cutting movement and support elements located between said drives and the rockers and that the support elements are shortenable to an effective cutting position to produce a cut.
In another aspect, the present invention resides in flying shears with cutting tools located on drums facing each other, which tools are accelerable by at least one driving device associated therewith to a peripheral speed corresponding to a speed of the strip to be cut and with a separately controllable adjusting device associated with a first one of said drums, wherein the second other one of said drums is mounted on rockers which are supported by means of support elements which are shortenable to an effective cutting position to produce a cut, the adjusting device has cranks which are connected with the first drum, and said first drum is movable to produce the cut through paraxial displacement towards the second drum.
The invention is explained in greater detail by means of a drawing in which Figure 1 shows in schematic representation shears according to the invention, Figure 2 shows a further solution compared with Fig. 1 for the adjusting drive, Figure 3 shows the schematic representation of further shears according to the invention, and Figure 4 shows shears according to the invention integrated into a coiler.
Figure 1 shows shears 1 which have a drum 2 and a drum 3. The drum 3 is carried by a rocker 4. One arm of the rocker 4 is mounted pivotably around the pivot point 5.
The drum 2 has a chisel 6, whereas the drum 3 is equipped with an anvil 7. The drums 2 and 3 are rotary-driven by driving devices 8 to a peripheral speed corresponding to the speed of the running strip 9. Thereby a mechanical or electrical or electronic synchronization respectively is provided between the drives 8 and thus 3a between the drums 2 and 3. At the second end of the rocker 4, a support element 10 is located, which support element is adjustable in its length and consists essentially of a piston-cylinder unit 11. The support element 10 is lined to a crank 12 which is acted upon by a drive 13.
The function of the shears 1 is as follows: The drums 2 and 3 are kept constantly at a corresponding peripheral speed or brought before a cut to the necessary peripheral speed respectively by the drives 8. The crank 12 is likewise constantly driven or brought before a cut to the corresponding rotational speed respectively.
Thereby the ratio of the peripheral speeds between the drum 2 and the crank 12 can be set, for example to 1:8. A possible synchronization between the drum 2 and the crank 12 is indicated by the line 14 or the line 14' respectively. Through the rotary movement of the crank 12, the crank 3 is moved constantly to and fro along the arrow 15.
If this adjusting movement is to lead to the cut, the piston-cylinder unit 11 is driven together before the crank reaches the lower dead poinit and arrested if applicable. By this means the drum 3 is pivoted to a substantially reduced distance from the drum 2. On the next reaching of the lower dead point of the crank 12, the corresponding cut is then executed. Through the synchronization between the crank 12 and the drum 2 it is achieved that, when the crank 12 is positioned at the lower dead point, the chisel 6 is facing the anvil 7, so that the strip 9 can be separated.
Figure 2 shows that, instead of the adjusting drive consisting of the crank 12, the drive 13 and the support element 10, a piston-cylinder unit 16 can be used, whereby this piston-cylinder unit has two separately pressurizable pistons. The upper piston corresponds to that of the piston-cylinder unit '11, whereas the lower piston replaces the crank 12 and the drive 13.
Figure 3 shows shears 1' which consist of the drums 2' and 3', whereby the drum 3' is held on the rocker 4'. The drum 2' is eccentrically mounted by means of a crank 12'.
By means of an arresting device 17, the rocker 4' can be locked in the lower position of the piston of the piston-cylinder unit 11'. The function of the shears 1' is as follows:
The drums 2' and 3' are constantly driven or accelerated before a cut to a corresponding . CA 02323356 2006-10-11 peripheral speed respectively by the motor 8'. The same applies to the crank 12', which is acted upon by the drive 13'. By this means the drum 2' executes, besides the circular movement effected by the driving device 8', a superimposed stroke movement effected by the crank 12'. If the strip 9' is to be cut, the piston-cylinder unit 11', before the chisel 6' reaches its upper point in the drawing, is retracted and blocked by the arresting device 17. By this means the distance between the drums 2' and 3' is so strongly reduced that the strip 9' is separated by the chisel 6' on the next reaching of the upper dead point.
Figure 4 shows a reverse coiler 18, whereby the strip 9 is led over a guide pulley 19 to the coiler 20. If the coiler 20 has the given number of windings and the strip 9 is to be cut, the drum 2' ' is pivoted against the coiler 21, whereby the pivoting movement can be executed as specified with respect to Fig. 1 or Fig. 3. The coiler 21 acts as the corresponding anvil. After the executed cut, the strip 9 can be coiled immediately into the coiler 21.
Similar shears have become known through DIE-OS 21 38 478. These shears are, however, intended for the cutting of fast-running wire. For the cutting of strips, DE-OS 41 28 970 discloses linear guides for the drums, which guides are located in stands.
