Description

Tux head of rolling system {A TURKS-HEAD OF ROLLING MILL}

The present invention relates to a tux head of a rolling system, and more particularly, to a tux head of a rolling system having four rolling rolls for rolling a wire rod wound on a winding bobbin in a predetermined cross-sectional shape to produce a release wire. It is about.

In general, the release wire is to refer to the wire rod other than the concentric section, the rolling production process is carried out through the tux head is equipped with two pairs of rolling rolls on the rolling stand.

That is, the tux head of the conventional rolling system is a pair of horizontal rolling rolls arranged to the left and right to idle at a predetermined distance to the rolling stand, and a pair arranged vertically in the direction orthogonal to the pair of horizontal rolling rolls It consists of a vertical rolling roll, and a drive unit for directly transmitting a driving force to a pair of vertical rolling rolls installed up and down.

Therefore, the rolling rolls roll while rotating the wire rod passing between them. At this time, since the rolling rolls are provided in four directions, surface roughness is better than drawing, and accurate dimensions and shapes and improved metallization can be obtained. In addition, in a pair of vertical rolling rolls that receive power and rotate through the driving unit, the driving force is transmitted to the wire rod while the rolling function serves to transfer the rolled wire rod in parallel.

However, in the tux head of the conventional rolling system, a pair of vertical rolling rolls disposed up and down rotates while receiving a driving force, but a pair of horizontal rolling rolls disposed left and right only idle in place. Therefore, when the release wire passes between the rolling rolls, a loss of driving force occurs in a pair of horizontal rolling rolls, and thus, a slip phenomenon occurs in a pair of vertical rolling rolls, and thus, rolling often does not proceed smoothly. do.

In order to solve this problem, the present inventors simultaneously drive four rolling rolls to prevent slip phenomenon while applying a uniform reduction force, the tux head of the rolling mill capable of driving in four directions to roll the wire rods (application number: 10-2002-0009788).

As shown in FIG. 1, the tux head of the rolling mill capable of driving in four directions disclosed in Application No. 2002-9788 is connected to a speed reducer (not shown) that decelerates and outputs power of a driving motor (not shown). Universal joint (1a) (1b), the upper drive shaft (3a) rotatably disposed in the frame (2) of the tux head and coaxially coupled to the upper universal joint (1a), and coupled to the upper drive shaft (3a) The upper rolling roll 4a, which is rotated and is rotatably disposed on the frame 2, and is coupled to the lower drive shaft 3b, which is coaxially coupled to the lower universal joint 1b, and coupled to the lower drive shaft 3b. The lower rolling roll 4b, the right driven shaft 5a connected to and rotated in the direction orthogonal to the upper drive shaft 3a through a power transmission means, and the right rolling coupled to the right driven shaft 5a and rotating. The roll 6a and the lower drive shaft 3b are directly driven by a power transmission means. And a left driven shaft (5b) connecting the rotation in a direction, are coupled to the left driven shaft (5b) equipped with a left rolling rollers (6b) which rotates.

The power transmission means includes driving bevel gears 7a and 7b mounted on the upper and lower driving shafts 3a and 3b, respectively, and left and right driving shafts 5a and 5b to mesh with the driving bevel gears 7a and 7b. ) Consists of driven bevel gears (8a) and (8b), respectively.

In addition, the upper and lower rolling rolls 4a and 4b and the left and right rolling rolls 5a and 5b are provided to be movable in four directions on the frame 2 of the tux head through the blocks 9, respectively. The block 9 is provided with an adjustment screw 9a for position adjustment.

When the driving motor is started in the rolling mill configured as described above, its power is transmitted to the upper and lower driving shafts 3a and 3b through the upper and lower universal joints 1a and 1b and rotates in one direction. For this reason, while the upper and lower rolling rolls 4a and 4b rotate, a pressing force is applied to the upper and lower surfaces of the release wire rod passing between them. In addition, power is also transmitted to the left and right drive shafts 5a and 5b through the driving bevel gears 7a and 7b and the driven bevel gears 8a and 8b so that the left and right rolling rolls 6a and 6b are also rotated. Apply a pressing force to the left and right sides of. As a result, all of the four rolling rolls 4a, 4b, 5a, and 5b arranged up, down, left, and right are rotated by receiving the driving force, so that the transfer of the release wire is more smoothly performed, and the reduction ratio is also improved.

On the other hand, when the cross-sectional size of the mold release wire varies, the gap between the upper and lower rolling rolls 4a and 4b and the gap between the left and right rolling rolls 5a and 5b are adjusted through the adjustment screw 9a. Even in this case, between the upper and lower rolling rolls 4a and 4b and the driving bevel gears 7a and 7b so that the meshing between the driving bevel gears 7a and 7b and the driven bevel gears 8a and 8b is precisely engaged. The spacer 10 is arrange | positioned at this. Therefore, the driving bevel gears 7a and 7b and driven bevel gears 8a and 8b are set to be correctly engaged through the thickness of the space 10 and whether it is removed.

However, in the tux head of such a conventional rolling mill, as the positions of the four rolling rolls 4a, 4b, 5a, and 5b are adjusted, the driving bevel gears 7a, 7b and driven bevel gears 8a, 8b are separated. The disadvantage is that the interlocking adjustment is difficult.

That is, since the driving bevel gears 7a and 7b and the driven bevel gears 8a and 8b are interlocked with each other by adjusting or removing the thickness of the spacer 10, it is of course difficult to adjust them. If the correct engagement is not achieved between the two, there is a fear that significant operating noise may occur during rolling.

The present invention is to solve this problem; An object of the present invention is to drive the four rolling rolls through the driving bevel gears and driven bevel gears to drive the power, thereby increasing the reduction rate, that is, the reduction rate of the release wires, thereby increasing the production workability of the release wires To provide the tux head of a rolling system.

In addition, another object of the present invention is to provide a tux head of a rolling system that can be easily adjusted by adjusting the interlocking between the driving bevel gear and the driven bevel gear when adjusting the position of the rolling roll.

Reference numeral "90" denotes a fixing nut for preventing the adjusting screw 84b from rotating arbitrarily.

Next will be described the operation and the effects of the tux head 40 according to the present invention configured as described above.

First, when the driving motor 31 is started in the rolling system, its power is appropriately reduced through the reducer 32. Subsequently, the decelerated power is transmitted to the first drive shaft 42a and the second drive shaft 42b through the first and second universal joints 33a and 33b to rotate.

As a result, while the first rolling roll 51 of the first block 43a and the second rolling roll 52 of the second block 43b rotate, a pressing force is applied to the upper and lower surfaces of the release wire A passing through them. Due to this, the release wire (A) is pushed and transported while rolling.

In addition, the first driving bevel gear 61 and the first driven bevel gear 71 rotate in engagement with each other to directly rotate the third rolling roll 53 of the third block 43c and the second driving bevel gear 62. And the second driven bevel gear 72 are engaged to rotate to directly rotate the fourth rolling roll 54 of the fourth block 43d. Accordingly, the third and fourth rolling rolls 53 and 54 disposed on the left and right sides are also driven directly by receiving power, so that a significant pressing force is also applied to the left and right sides of the release wire A to be rolled and at the same time the release wire ( A) transfer is made more smoothly.

As a result, the first and second rolling rolls 51 and 52 which are vertically positioned and the third and fourth rolling rolls 53 and 54 which are horizontally positioned are simultaneously driven by power to reduce the reduction of the release wire A. The rate is higher, which increases productivity.

On the other hand, when the cross-sectional size of the release wire (A) is different, the first to fourth blocks 43a, 43b, 43c, 43d are appropriately moved to the rolling rolls 51, 52, 53, and 54. ) To adjust the gap.

Even in this case, in order to simultaneously drive the four rolling rolls 51, 52, 53, and 54, the driving bevel gears 61, 62 and driven bevel gears 71, 72 should always be engaged. This is done by the adjusting means 81, 82, 83, 84.

That is, when the first block 43a is moved up and down, the first driving bevel gear 61 is moved by rotating the adjusting screw 82b of the second adjusting means 82 to move the spline shaft 82a up and down. And first driven bevel gear 71 are correctly engaged.

When the third block 43c is moved to the left and right, by loosening the fixing bolt 81b of the first adjusting means 81 and moving the first driving bevel gear 61 to the left and right on the spline shaft 81a, The first driving bevel gear 61 and the first driven bevel gear 71 are correctly engaged.

In addition, in the case where the fourth block 43d is moved left and right, the adjusting screw 83b of the third adjusting means 83 is rotated to move the second drive bevel gear 62 from side to side on the spline shaft 83a. In this way, the second driving bevel gear 62 and the second driven bevel gear 72 are correctly engaged.

In addition, when moving the 2nd block 43b up and down, the 2nd drive bevel gear 62 by rotating the adjustment screw 84b of the 4th adjustment means 84, and moving the spline shaft 84a up and down. ) And second driven bevel gear 72 are correctly engaged.

Therefore, even if the first to fourth blocks 43a, 43b, 43c and 43d are moved, the adjusting screws 82b, 83b and 84b of the adjusting means are rotated or the fixing bolts 81b are loosened and tightened. Accordingly, the engagement of the driving bevel gears 61 and 62 and the driven bevel gears 71 and 72 can be easily and accurately set.

As described in detail above, according to the tux head of the rolling system according to the present invention, the power is transmitted to all four rolling rolls through the driving bevel gear and the driven bevel gear, thereby reducing the reduction rate, that is, the reduction ratio of the release wire. This has the effect of improving the rolling productivity of the release wire.

In addition, even when the rolling roll is mounted on the block, the action effect of easily and accurately setting the interlocking of the driving bevel gear and the driven bevel gear through the adjusting screw or the fixing bolt of the first to fourth adjusting means is also effective. have.
