Description

Coil tip grinding device {APPARATUS FOR GRINDING TOP PORTION OF COIL FOR REMOVING END MARK}

The present invention prevents end marks in the strip width direction caused by the thickness difference of the strip material when the leading end of the strip is wound in a tension reel operation in which a strip is wound in a steel mill to produce a product in the form of a coil. A coil tip grinding device is provided.

FIG. 1 illustrates a tension reel process of a strip that is generally performed in order to manufacture a slab cast in a steel mill and ship it as a coil product.

That is, as shown in FIG. 1, in order to ship the strip 100 to the coil product 110 or to put it in a continuous process, the strip is continuously connected to the welding machine 120 and wound up in the tension reel 130. will be.

On the other hand, as shown in the main part of Figure 1, since the thickness difference (T) of the strip 100 occurs in the coil tip end portion (110a) in the inner winding portion of the coiled coil 110, after the winding operation of the strip is completed In the coil product 110, an end mark E is generated at a constant pitch, that is, a pitch equal to the circumferential pitch of the strip coil.

Therefore, in order to prevent the end mark (E) from occurring in the inner winding portion of the strip coil 100 as described above, a sleeve (sleeve), which is a cylindrical support cylinder in the inner winding portion when the coil 100 is wound, is The tension reel 130 was placed in the coil inner portion at the beginning of the operation to prevent the end mark E of the coil as described above.

However, in the case of using the sleeve as described above, in order to fix the tip of the coil by fixing the groove in the width direction in the cylindrical sleeve so that the tip of the coil strip to the tension reel 130 at the beginning of the work of the tension reel 130 Since the coil is inserted to guide the strip tip to the elastic extension of the rubber and the machined outer winding fixing groove to perform the coil winding operation, the coil 100 is wound around the strip 100 to which a constant tension is applied. As a separate operation is added, there is a problem in that the winding speed of the tension reel 130 is not matched with the strip line feeding speed, which causes the strip feeding speed, that is, the delay of the production line.

Meanwhile, another conventional coil end mark prevention operation for avoiding the above problem is to grind the tip of the coil strip to maintain a constant angle by using a grinder before the strip 100 is put into the winding machine. It is.

That is, by grinding the tip end portion 110a of the coil 110 inclined with a grinder to prevent the continuous end mark (E) generation of the coil inner peripheral portion due to the thickness (T) of the coil tip portion.

However, in another conventional coil end mark prevention operation by the above grinding method, not only the grinding operation of the coil tip portion 110a, in which the operator grinds the coil tip portion 110a by hand, is significantly delayed, in particular, the processing thereof. There are several problems, such as the degree of inconsistency and the inadequate end-to-end preventive work during worker misoperation.

And, there is also a conventional method of reducing the thickness difference of the coil end portion 110a by the hydraulic press crimping method, which can reduce the working time by processing the coil end portion 110a by one press work, but in the case of a thin strip Since the coil tip 110a cannot be processed at a sharp angle during processing, there is a problem in that the effect of preventing the occurrence of the end mark is insufficient.

The present invention was devised to improve the above-mentioned problems, and its purpose is to generate the coil in the inner portion of the coil due to the difference in thickness of the tip of the coil during winding the coil into a coil for continuous process or product shipment. An object of the present invention is to provide a coil end grinding device which completely prevents end marks.

In addition, another object of the present invention, the coil tip can be ground and tapered at a time automatically and continuously in a continuous operation can be put into the tension reel process in a continuous line to perform a coil winding of the tension reel more quickly to improve the coil manufacturing productivity It is to provide a coil tip grinding device to improve.

4A and 4B, the grinding roll 46 has a coil tip portion along the circumference of the roll body 46b and the roll body 46b in which the shaft portion 46a is integrally formed on both sides. It consists of a grinding jig 46c, which is provided with a plurality of tapered grinding (10a).

Next, FIG. 2 and FIG. 5 show the coil discharge part 60. The coil discharge part 60 of the present invention is pivoted as the operating motor 62a in front of the coil grinding part 40. It is provided with the guide table 62 which is provided in the edge part of the discharge table 64, and guides discharge | emission of the coil 10 by which the front-end | tip part 10a was tapered-grinding so that it may exercise | move.

As shown in FIGS. 2, 4A, and 5, upper, lower, and one sides of the coil grinding part 40 may include a first sensor S1 and a switch for detecting the entry of the coil tip part 10a. Second and third sensors S2 and S3 for detecting the movement of the topping plate 44 and the grinding roll 46 are respectively provided, and the turning operation of the table is performed at the upper and lower points of the discharge table 62. The fourth sensor S4 for sensing is configured to be disposed respectively.

Referring to the operation and effects of the present invention made in the above configuration in more detail as follows.

As shown in FIGS. 2 to 6, when the strip 10 is wound as a tension reel, an end mark is formed in the inner portion of the coil strip 10 wound by the thickness difference of the tip portion 10a. Coil tip grinding device 1 of the present invention to automatically taper the coil tip 10a immediately before the tension reel operation of the strip 10 to effectively prevent the generated is as follows.

First, as shown in FIGS. 2 and 3, the leading end portion 10a of the strip 10, which is continuously connected by welding and wound in a coil, enters the apparatus 1 through the entry table 22. When detected as two photosensors S1 installed above and below the vertical stand 42 of the device 10, the first cylinder 28 of the coil entry portion 20 acting as the sensor (S1) is In the lowering operation, a clamping plate 24 connected to the rod end of the first cylinder 28 clamps the coil tip 10a on the entry table 22.

At this time, as shown in Figures 2 and 6, when operating the operating motor 44a installed in the lower outer portion of the vertical stand 42, the worm wheel (connected to the operating motor 44a and installed in the gear box 44b) The stopper plate 44, which is engaged with the worm shaft 44c, moves upwardly and is horizontally fixed to the upper end of the worm shaft 44c to accurately fix the position of the coil tip 10a that is entered. The plate 44 always enters a constant position during grinding of the coil tip 10a.

And, as described above, when the front end portion 10a of the strip 10 entered as two plates, namely, the clapping plate 24 and the stopping plate 44, is fixed, the vertical stand of the grinding portion 40 The second cylinder 48 mounted upward is lowered.

Therefore, as shown in FIGS. 4 and 6, the movable plate 50 horizontally fixed at the lower end of the rod 48a of the cylinder 48 is lowered integrally and fixed to both sides of the bottom of the movable plate 50. The grinding roll 46, which is equipped with both shaft portions 46a on the bearing block 52, is also lowered integrally, and depending on the position close to the coil tip portion 10a, the grinding roll 46 is horizontally positioned on the movable plate 50. The operating motor 45 on the fixed fixing plate 54 is operated.

As a result, as shown in Figure 4a, the grinding roll shaft portion 46a is connected through the operating motor 45 and the bearing block 52, the grinding roll 46 is shown in Figures 4b and 6 As described above, the coil 10 rotates in the advancing direction.

Therefore, the roll body 46b, which is formed integrally on both sides of the roll shaft portion 46a, which is rotated by the driving motor, is integrally rotated and integrally formed in the width direction along the circumferential surface of the roll body 46b. The grinding jig 46c fixed by the grinding | pulverization grinds the said coil tip part 10a so that it might taper, as shown in the principal part figure of FIG.

Accordingly, the end of the coil 10, which is ground so that the tip portion 10a is tapered by the grinding roll 46, the coil inner winding portion is pressed by a constant pitch interval due to the thickness difference of the tip portion even when the coil 10 is wound as a tension reel. The mark is effectively prevented.

That is, the vertical movement of the grinding roll 46 connected to the bottom of the movable plate 50 is detected by the third sensor S3 by detecting the horizontal plate 54 installed on one side of the movable plate 50. 46) the vertical movement is also adjusted.

In addition, when the grinding operation of the tip portion 10a as described above is performed, the operation motor 62a installed on one side of the discharge table 64 is operated to pivot the guide table 62 connected through a bearing block (not shown). Let's do it.

That is, when the coil 10 initially enters the apparatus, the coil 10 is turned upward to prevent the coil 10 from being discharged. On the contrary, when the grinding of the coil tip portion 10a through the grinding roll 46 is completed, the guide table ( 62) is operated in an initial horizontal state to guide the coil, the tip portion (10a) is ground more smoothly.

Accordingly, after the operator manually grinds the coil tip 10a by hand, it occurs more easily and quickly when winding up the coil strip without delaying the line feeding speed, compared to performing the winding operation of the strip 10. It is possible to effectively prevent end marks.

The fourth sensor S4 is provided at the upper and lower points of the discharge table 62 to adjust the swing width of the guide table 62.

As a result, in the present invention, a coil 10 continuously entering automatically is provided in the present invention, as compared with a conventional worker treating the tip portion 10a of the coil 10 by manual or press work to prevent generation of end marks during coil winding. The tip portion 10a of the () is ground, so that the work is considerably fast while completely preventing the generation of the end mark during winding on the tension reel.

As described above, according to the coil tip grinding device of the present invention, an advantage of completely preventing end marks generated in the inner coil part due to the thickness of the coil tip part during the tension reel operation in which the strip is wound into the coil for continuous processing or product shipment. have.

In addition, the tip of the coil can be ground and tapered automatically and continuously in a continuous operation to be introduced into the tension reel process in a continuous line, thus providing a superior effect of improving coil manufacturing productivity by performing coil winding of the tension reel more quickly. will be.
