BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic inner ring manufacturing apparatus for packing an iron coil, and more particularly, to an automatic inner ring manufacturing apparatus for packing an iron coil, which can produce an inner ring of various diameters with a simple operation and reduce a defect rate.

As shown in Fig. 1, the inner ring 1 for packing the iron coil serves to protect the steel coil during transportation by a packing member attached to the inner diameter portion of the produced iron coil.

The inner ring 1 is formed in an annular shape in cross section in the shape shown in Fig. 1 and overlapped with both ends in the shape of "a ". At this time, the projecting portion is coupled to the inner diameter of the iron coil shown in FIG. 1 to serve as a protector for protecting the inner diameter edge portion of the inner diameter end and the side face of the iron coil.

The manufacturing method of the inner ring 1 is firstly bent in a "? &Quot; shape using a long straight plate member 3. The bending utilizes multiple rolls, bending about 30 degrees in the initial roll, and bending at 90 degrees in the final roll at 60 degrees on the second roll.

The bent plate is processed into an annular inner ring by using two conical rolls to finally complete it. The conical roll is a conical roll formed with a horizontal portion and a constant inclination, and the diameter of the inner ring 1 is determined by the inclined size.

In the case of the above apparatus, the diameter of the inner ring 1 is determined by the angle of the cone roll, so that it is inconvenient to replace the cone roll in order to manufacture the inner ring 1 of different diameter.

Further, in the apparatus, in the process of bending the plate, the plate may be bent due to the characteristics of the roll. This warpage is formed on the side surface of the bent plate material. The side face of the plate material is a portion in contact with the inner diameter of the iron coil and is an important portion rounded in the subsequent annular machining. If the steel material is deviated from the design shape due to an unexpected warping, a bad inner ring can be produced and a problem is posed.

The inner ring manufacturing apparatus according to the present invention comprises a bending section, a feeding device 10, an orthogonal section 30 and an annular section 40, as shown in Fig.

The feeding device 10 comprises a plate material supply portion 11, a tensioner 12, and a feeding portion 13.

3, the plate material supply unit 11 includes a rotating supply shaft 11a, a supply motor 11b for rotating the supply shaft 11a, a rotary reel (not shown) fixed to the supply shaft 11a, And a tension sensing unit 11d for sensing the tension of the seat 3 released from the rotary reel 11c.

Here, the rotating reel 11c can be separated from the supply shaft 11a when necessary. The rotary reel 11c is horizontally disposed on the ground so that the plate 3 is fed in a direction perpendicular to the ground in a subsequent process.

Further, the plate 3 is wound around the rotary reel 11c, and the plate 3 released from the rotary reel 11c is supplied to the process after passing through the tension detecting portion 11d.

The tension sensing unit 11d is configured in the form of a pneumatic cylinder that presses the plate 3 to the side. When the tension of the plate 3 is higher than a certain level, the stroke of the tension sensing unit 11d is reduced, The supply motor 11b functions to rotate. That is, when the tension force of the plate member 3 is equal to or higher than a certain level, the supply motor 11b rotates to release the plate member 3.

The sheet material 5 discharged from the sheet material supply unit 11 is supplied to the tensioner 12 shown in FIG.

The tensioner 12 serves to regulate the supply of the plate 3 to a subsequent process and includes a base 12a and a plurality of guides 12b crossing the base 12a, A plurality of moving rollers 12d coupled to the upper end of the moving body 12c to rotate along the moving body 12c, a pneumatic cylinder 12f connected to the moving body 12c, And a plurality of guide rollers 12e that engage with the guide rollers 12e.

The base 12a is formed in a rectangular cross section and a guide roller 12e is coupled to each side of the plate 12 and the sheet material 3 supplied from the sheet material supply unit 11 and the plate material 3 ) And supplies it to the subsequent process.

On the other hand, the moving body 12c is attached to a rod where a stroke of the pneumatic cylinder 12f is generated, and pneumatic pressure is supplied to both sides of the piston in the pneumatic cylinder 12f, So that the moving body 12c is transported downward.

When the plate member 3 passes over the moving roller 12d and the tension of the plate member 3 is greater than the force due to the pressure difference of the pneumatic cylinder 12f, the moving member 12c moves, 3) acts to reduce the tension of the plate material (3), and in the opposite case acts to increase the tension of the plate material (3) so as to maintain the tension at a constant level. The tension of the plate material (3) The pressure difference acting on the piston side of the piston.

The guide rollers 12e may be arranged in various forms other than the arrangement shown in FIG.

On the other hand, the plate member 3 having passed through the tensioner 12 is supplied to the feeding portion 13.

5, the feeding part 13 is constituted by a pair of opposing rollers and is constituted of an inlet roll 13a to which the plate 3 is fed and a pair of rollers facing each other, A sheet guide 13c disposed between the pulling roll 13a and the pulling roll 13b and guiding the sheet 3 includes a sheet guide 13c which is provided between the sheet guide 13c and the sheet roll 13b, And a plurality of feeding rolls 13d disposed at a position opposite to the guide 13c to feed the plate 3.

Wherein the drawing roll 13a, the drawing roll 13b and the feeding roll 13d are driven to rotate at the same linear velocity and the plate guide 13c includes a partially opened portion 13e, And the feeding rolls 13d are positioned in the portion 13e.

At least three feeding rolls 13d are advantageous in terms of feeding the sheet material 3, and five feeding rolls 13d are provided in the embodiment of the present invention.

On the other hand, the plate material 3 having passed through the feeding portion 13 is fed to the bent portion.

As shown in Fig. 6, the bending portion is a portion for bending the rectangular plate so that its cross-section is in the shape of a letter "A", as a first processing roll 21, a second processing roll 22 and a third processing roll 23, . Here, the angle of the upper end of the first processing roll 21 is inclined at 30 degrees, the upper end of the second processing roll 22 is inclined at 60 degrees, and finally the angle of the upper end of the third processing roll 23 is 90 degrees When the plate member 3 passes through the third processing roll 23, it finally becomes "a ".

Three first, second and third flat rolls 24 are formed so as to correspond to the first, second and third processing rolls 21, 22 and 23, respectively, The first and second processing rolls 22 and 23 are positioned between the first and second flat rolls 24 and 23 and between the first and second processing rolls 21 and 22 and 23, , 2,3 flat rolls (24).

The lower portions of the first, second, and third flat rolls 24 and the first, second, and third processing rolls 21, 22, and 23 are preferably the same diameter, So that the linear velocity of the plate material 3 is constant.

The rolls are operated by gears with the same power source.

The feeding device 2 is positioned before the first processing roll 21 and automatically feeds the plate material 3 to the bending part and the feeding device 2 feeds the plate material between the rolls using two rolls Which is the same as a conventional feeding device, and is operated by a gear, which is also a power source of the same power source.

The plate member 3 bent at the bent portion is formed with a side surface and a bent upper surface, and is conveyed to the calibrating unit 30.

As shown in FIG. 7, the calibration unit 30 is provided with first and second calibration rolls 31 and 32 arranged to face each other with a gap therebetween, . In this case, the first and second calibrating rolls 31 and 32 are cylindrically shaped, and the side surface of the plate material bent at the bent portion passes between the first and second calibrating rolls 31 and 32. The upper surface of the plate member bent at the bent portion passes over the upper portion of the first calibration roll 31. In the orthogonal portion 30, the side surface of the plate member bent at the bent portion is pressed and flattened to impart straightness.

The first and second calibrating rolls 31 and 32 preferably have the same diameter and are driven at the same rotational speed so that the linear velocity of the plate 3 is constant.

The plate material is "sequentially bent" by the first working roll 21, the second working roll 22 and the third working roll 23 whose upper ends are inclined at the bent portions, so that unpredictable warping and bending Lt; / RTI > In particular, warping and bending formed as a continuous wave on the side surface of the plate material may cause process errors and defects in the later-described annular processing step. In addition, the side surface of the plate member is a portion contacting the inner circumferential surface of the packaged coil to fix the coil. Therefore, the poor inner circumferential ring can not completely contact the inner circumferential surface of the coil due to warpage and bending generated on the side surface of the plate during packaging of the coil, and the bonding force is weak.

In order to solve such a problem, the calibrating unit 30 of the present invention ensures the flatness and straightness of the side surface of the plate member bent by the first and second calibration rolls 31 and 32.

The plate member 3 calibrated by the calibration unit 30 is conveyed to the annular portion 40.

The annular portion 40 is a portion for machining the plate member 3 bent in the "a" shape into an annular ring 1 of an annular shape. As shown in Fig. 8, the upper roll 41, the lower roll 42 , The side rolls 43 and the knife 50 as the pressing means are finally finished into the annular inner ring 1 by the plate material 3 bent by the four constitutions.

The upper roll 41 rotates about the horizontal axis and the lower roll 42 is separated from the upper roll 42 by a predetermined distance and corresponds to the upper roll 41, But it is advantageous to reduce the interference with the knife 50 because the diameter is smaller than that of the upper roll 41. [

The upper roll 41 is tapered to linearly deform the linear plate 3 in an annular shape and the taper is formed so that the plate 3 is bent in the lateral direction of the upper roll 41 desirable.

The lower roll 42 is driven by the power that branches off from the power shaft of the upper roll 41, but may be driven by a separate power if necessary.

On the other hand, a side roll 43, which rotates in a vertical axis, is positioned at the side of the lower roll 42. The side rolls 43 are adjacent to the lower rolls 42 and may be rotated by a separate power. If necessary, the side rolls 43 may be driven and rotated only by friction of the plate material without any additional power.

The upper surface of the bent plate is interposed between the upper roll 41 and the lower roll 42 and the side is interposed between the lower roll 42 and the side roll 43 and transported. In this case, the bent plate member is moved to a constant line speed matching the design request by the lower roll 42 and the side roll 43 because the flatness and straightness of the side are improved by the rectifying unit 30 . As a result, process defects and errors can be reduced.

On the side surface of the lower roll 42, a knife 50 as a pressing means is located. The end of the knife 50 is formed in a relatively sharp shape and is in frictional contact with the side surface (more specifically, the outer side surface) of the plate material 3. Since the pressing force of the knife 50 is supported by the side rolls 43, it is directly transmitted to the plate member 3, and the plate member 3 is rounded by the pressing force. That is, the plate member 3 can form a ring shape by the knife 50.

In this case, the bent plate member 3 can be brought into frictional contact with the contact force matching the design request with the knife 50, since the flatness and straightness of the side are improved by the orthogonal portion 30. As a result, process defects and errors can be reduced.

The knife 50 is installed on a knife guide 55 for forward and backward transport and the knife 50 moves according to the knife guide 55. If necessary, And is fixed to the knife guide 55. The knife 50 moves in the longitudinal direction along the knife guide 55 and the diameter of the inner ring 1 can be adjusted according to the degree of movement of the knife 50.

On the other hand, two support rolls 47 for supporting the processed plate material 3 are disposed on the upper end of the knife 50. The two support rolls 47 are used to simply process the plate material 3, It is not driven by a separate power.

The transfer of the knife 50 can be controlled manually and, if necessary, can be automatically adjusted by mounting a separate actuator.

It is preferable that the knife 50 has a sharp end which is configured to press the plate 3 from the side to induce deformation.

The knife 50 may be installed perpendicularly to the rotation axis of the upper roll 41. However, the knife 50 may be partially inclined outwardly of the plate 3 to avoid interference with the plate 3.

Further, the annular portion 40 of the present invention may further include a curvature correcting device for correcting the plate material rounded by the knife 40. [ The curvature correcting apparatus includes a main body 60, a moving member 61, and third and fourth correcting rollers 62 and 63 as shown in Fig. However, the curvature correcting device may not be an essential component of the present invention.

The main body 60 is a member that forms the appearance of the curvature correcting device. The movable member 61 is slidably engaged with the main body 60 (see arrow A in Figs. 11 and 12). The third and fourth calibrating rollers 62 and 63 are disposed on the moving member 61 and at least one of the third and fourth calibrating rollers 62 and 63 is slidably engaged with the moving member 61 12).

The third and fourth straightening rollers 62 and 63 are disposed adjacent to each other so as to come in contact with the side surface (in detail, outer side surface) of the plate material 3 rounded by the knife 50. Therefore, the rounded plate member 3 is sequentially circumscribed by the third correcting roller 62 and the fourth correcting roller 63.

In the process of rounding the plate material 3 by the knife 50, the property of the plate material 3, the feeding error of the plate material 3, the upper roll 41, the lower roll 42, the side rolls 43, The curvature of the plate material 3 may not be constant due to the subtle detachment of the knife 50. [

The curvature correcting apparatus is a device for calibrating the curved plate material 3 so that the curved plate material 3 has a constant curvature. When the rounded plate material 3 is in contact with the third and fourth correcting rollers 62 and 63 in sequence, (See the dotted line a in Figs. 9 and 12).

When the radius of the inner ring 1 is changed, at least one of the shifting member 61 and the third and fourth correcting rollers 62 and 63 is slid so that the third and fourth correcting rollers 62, Can be adjusted to contact the outer surface of the rounded plate material (3).

That is, the radius of the inner ring 1 can be changed, and the main body 60 is not always arranged to face the center of the inner ring 1, so that the third and fourth correcting rollers 62, 3, sliding movement of at least one of the third and fourth correcting rollers 62 and 63 as well as the sliding movement of the moving member 61 is required.

The inner ring manufacturing apparatus 100 according to the above construction is configured such that the entire roll is driven by a single motor, and the same sheet material 3 is fed at the same speed in consideration of the diameter of each roll, And the sheet material 3 is fed vertically into the initial feeding device 10, finally the annular inner ring 1 is produced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, And all of the various forms of embodiments that can be practiced without departing from the technical spirit.
