The driven shaft 20 is positioned above the main coaxial shaft 10 so as to be positioned above the spacing space between the plurality of main coaxial axes 10. [

The driven shaft 20 is a rotary shaft having the same diameter as the main coaxial shaft 10 and has the same circular cross section, and no separate rotation drive device and power supply device are connected. That is, in the insertion space A formed between the main coaxial shaft 10 and the above-described main coaxial shaft 10, the metal plate P to be bended (in the form of a cone, The metal plate P to be bended is rotated with the plurality of main shafts 10 and the single main shaft 10 as the main coaxial shaft 10 is rotated when a metal plate of a straight straight line or a straight metal plate which can be a cone- The metal plate P to be bent is discharged in one direction as the upper and lower surfaces of the main coaxial shaft 10 of the main shaft 10 come into close contact with each other and are discharged in one direction (towards the front of the main coaxial shaft 10) To have a structure that is accompanied together.

In addition, the driven shaft 20 is provided so as to be able to move up and down between the main coaxial axes 10 and to adjust the left and right angles. Shaped bending target metal plate P passing between the driven shaft 20 and the driven shaft 20 can be bent in a cone shape, which will be described in detail below in the bending operation portion 30 portion.

The main coaxial shaft 10 is provided so as to be rotatable upright and the mounting recesses H are formed at the both ends thereof.

The movable body 32 is internally provided so as to correspond to each of the mounting recesses H formed in the columnar portions 31 on both sides of the main coaxial shaft 10. The plurality of The moving bodies 32 are provided with both end portions of the driven shaft 20 inserted and mounted.

The pneumo-hydraulic pressure portion 33 is connected to the moving body 32 from the upper portion of the column portion 31 to allow the moving body 32 to flow upward and downward. So that the moving body 32 can be moved up and down. Since the plurality of moving bodies 32 can be separately operated by the pneumatic / hydraulic pressure units 33, the slave shafts 20 having both ends connected to the plurality of moving bodies 32 can be adjusted in the left and right heights, It is possible to adjust the inclination of the left and right at a predetermined angle? Without being horizontal with the main coaxial shaft 10.

The display unit 34 can be externally checked for the movement height and angle? Of the driven shaft 20. The indicator 35 is formed on the moving body 32 moving up and down, A scale portion 36 is formed in the mounting groove H of the column portion 31 to which the moving body 32 corresponds and to which the moving body 32 is moved so that the upper, When the elevation (the height of the movable body 32) and the elevation of the both ends of the driven shaft 20 are different from each other at both ends or one end of the driven shaft 20 through the indicator 35 and the scale unit 36, Allow the angle to be known.

The position intermittent portion 40 is bent in the insertion space A between the main shaft 10 and the driven shaft 20 when the bending metal plate P is to be discharged to the front surface So that the target metal plate P is not moved in the longitudinal direction of the main coaxial shaft 10 or the driven shaft 20.

That is, the main coaxial shaft 10 is rotated in a tilted state at a predetermined angle?, Whereby the upper and lower surfaces of a part of the entire width W of the metal plate P to be bent (bent portion) The metal plate P to be bent is lifted upwards and the driven shaft 20 or the main coaxial shaft 10 is lifted up while being bended and discharged. Since a force to move in the longitudinal direction of the stator 1 is generated

The position intermittent portion 40 for this purpose is composed of a mounting plate 41 and an intermittent member 44.

The mounting plate 41 is spaced forward from the main coaxial shaft 10 on one side (ex: front side) of the main coaxial shaft 10 and is provided continuously in the longitudinal direction of the main coaxial shaft 10 And such a mounting plate 41 is installed in a lower frame connecting the plurality of pillars 31 for fixing both ends of the main coaxial shaft 10 to each other.

The support member 42 is rotatably mounted on the mounting plate 41. The support member 42 is rotatably mounted on the mounting plate 41. The supporting member 42 is rotatably mounted on the mounting plate 41, And a bearing B is mounted on the inner and lower ends of the support body 42. The rotation shaft 43 is installed in the support body 42 in the longitudinal direction upright, (B).

That is, the intermittent body 44 is detachably installed vertically on one of the plurality of mounting plates 41 in accordance with the size of the metal plate P to be bent, so that the main shaft 10 and the driven shaft 20 In the whole length, the work space to be bendable is determined.

The position of the mounting plate 41 corresponding to the width W of the metal plate P to be bent from one of the column portions 31 is determined according to the size of the metal plate P to be bent among the plurality of mounting plates 41, The intermittent member 44 is fitted to the mounting plate 41 and fixed in the upright position. Of course, when the intermittent body 44 is erected upright, the rotation bar 43 is erected upright above the height of the follower shaft 20 at the front side where the metal plate P to be bent is bent and discharged. When the bendable metal plate P bends and bends while bending, a force for moving the bending target metal plate P in the longitudinal direction of the follower shaft 20 is generated. However, The one end of the target metal plate P is closely adhered to restrict the movement of the driven shaft 20 in the longitudinal direction and the rotation of the rotating rod 43 in contact with the metal plate P .

Of course, after the metal plate P to be bent is bent and formed into a cone shape through the above-described configuration, a shape correcting operation is performed so that both ends of the cone-shaped metal plate P to be bent can be accurately matched and matched, The brazing operation, the finishing work of rotating the end fittings in the insertion space (A) must be performed, and all of these operations are carried out in the state of being bent in the upper part of the driven shaft 20 and forming a cone shape.

Hereinafter, a method of manufacturing a metal cone-type bending according to the present invention having the above-described structure and structure will be described in detail.

1. A step S10 in which a plurality of main coaxial axes 10 are rotatably installed on the same horizontal line and a step S20 in which a subordinate axis 20 is installed on the main coaxial axis 10, A plurality of main coaxial axes 10 are rotatably arranged so as to be horizontal with respect to the ground, and a subordinate axis 20 is disposed above the plurality of main axes 10.

2. A bending target metal plate P inserted between the main coaxial shaft 10 and the driven shaft 20 is provided adjacent to the main coaxial shaft 10 so as not to move in the longitudinal direction of the main coaxial shaft 10 during the bending operation, The metal plate P to be bent is inserted between the main coaxial shaft 10 and the driven shaft 20 and is discharged and bent so that the metal plate P to be bent is inserted into the bendable metal plate P, But the metal plate P to be bent is pushed to one side while being bent and discharged toward one direction (front side).

The position intermittent portion 40 is vertically erected on the entire surface of the main shaft 10 or the driven shaft 20 in accordance with the width W of the metal plate P to be bent before the bending operation, Work is progressed and discharged only between the position intermittent portion 40 provided with the target metal plate P and the column portion 31 so as not to move in the longitudinal direction of the main shaft 10 during the bending operation.

3. The installation height of the driven shaft 20 and the left and right angles? Are set in accordance with the predetermined cone angle of the metal plate P to be bent (the angle at which the cone gradually decreases or increases in diameter from one side to the other) A step S40 in which the main coaxial shaft 10 is rotated and a metal plate inserted into the insertion space A between the main coaxial shaft 10 and the driven shaft 20 becomes a cone shape S50: The step of adjusting the height of the driven shaft 20 to be positioned between the main coaxial shaft 10 and the degree of inclination of the left and right sides of the driven shaft 20 without being horizontal, And the bending operation portion 30 is installed.

That is, when the distance between the main shaft 10 and the driven shaft 20 is too great, the driven shaft 20 is disposed between the main coaxial axes 10 that are mutually corresponding to each other. The upper and lower surfaces of the plate material are brought into close contact with the main shaft 10 and the driven shaft 20 between the main shaft 10 and the driven shaft 20 so that the plate material is moved in one direction The follower shaft 20 should be height-adjusted up and down so as to be arranged at a preset height with the main shaft 10.

When the slave shafts 20 are arranged so as to be parallel to the left and right sides of the driven shaft 20, the metal plate P to be bent, which is inserted into and discharged from the insertion space A, is discharged without bending , And the left and right heights of the subordinate shafts 20 capable of upward and downward flow can be finely adjusted so as to be arranged at a predetermined angle (?) Which is not horizontal but tilts to one side.

The metal plate P to be bent which has been inserted into the insertion space A is guided by the slave shaft 20 inclined at a predetermined angle? Or when the entire width W of the plate material is all pressed, the more pressed width portions are bent and bent.

In other words, the main coaxial shaft 10 is rotated, and the metal plate P to be bent is passed between the main coaxial shaft 10 and the driven shaft 20, And the left and right tilt is finely adjusted, the metal plate P to be bent is bent in a cone shape.

However, instead of making the cone shape of the angle desired by the user in a single operation, the angle? Of the driven shaft 20 is gradually changed to be a predetermined angle desired by the user, P is repeatedly passed between the driven shaft 20 and the rotating shaft. As a result, the metal plate P to be bent in the straight plate material is gradually bent to a circular section and bent so that the diameter is reduced to such a degree that the both ends are gradually faced by the repeated process.

4. The method according to claim 1, wherein in operation S60, both ends of the metal plate to be bent are interposed between the metal plate P to be bent and the insertion space A, In the case of the shape correcting operation in which both ends of the metal plate to be bent are operated so as to correspond to each other, in the case of the shape correcting operation in which the brazing operation is performed (S70), the cone-shaped metal plate in which the brazing operation is completed is rotated in the insert space (A) It is necessary to move both ends of the metal plate P to be bent to the left, right and up and down so that both end portions face each other in the same manner. A correction mechanism C such as a clamp and a turnbuckle is used. The present invention can be variously changed by the user. (That is, after the bending operation of the metal plate P to be bended, when the both ends are shifted to the left and the right without being matched, the other side of one end and the other end are clamped in a diagonal shape with a clamp and then tightened with a turnbuckle, So that both ends can be faced in the same manner by using a turnbuckle or by using various striking devices (such as a hammer) as described above.

After the shape correcting operation as described above, the opposite end portions are welded to each other to form an integral body. Then, the conical bent metal plate P thus formed is sandwiched between the main coaxial shaft 10 and the driven shaft 20, While the coaxial shaft 10 is being rotated, the finishing work is performed so that the entire circle is fitted.

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. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
