The present invention relates to an apparatus for manufacturing a curved tube curvature for a flanged shim type duct, and more particularly, to improve work efficiency and to prevent work by manufacturing a curved tube in a flanged shim type duct. The present invention relates to a bend curvature manufacturing apparatus for shim type ducts having a flange to improve quality.

In general, the building is equipped with an air conditioner for indoor air conditioning and air circulation / purification, the duct (DUCT) is installed to supply the air conditioning air discharged from the air conditioner inside the building.

The duct is to be installed in a straight line and curve while connecting a plurality of ducts made of a predetermined length to each other, when forming a duct while forming a flange to maintain the strength of the connection and the connection portion of the duct A lot of seam-type ducts formed by overlapping each side are used.

When the duct as described above forms a square or a circular duct in a straight line, the duct is folded into a square or a circle, and the connecting portion forms a core to be joined, and then each duct is connected by a flange.

Here, the straight portion can be easily manufactured when manufacturing the flange-shaped shim type duct, but the curved portion of the curved portion is relatively difficult to manufacture, and most of them are manufactured by hand.

That is, as shown in FIGS. 10 and 11, the shim type curved pipe is formed by cutting both side plates 50 according to a predetermined curvature in advance and then combining the upper and lower plates 51 and 52 to the bar. First, the first core portion (fitted portion) 55 forming the flange 53 and the core portion 54 is formed at both ends of the two side plates 50 cut at a predetermined curvature.

In the state in which the flange 53 and the first core portion 55 are formed on the side plate 50, the upper and lower plates 51 and 52 corresponding to the curvature of the side plate 50 should be coupled. Forming 52) at a predetermined curvature is manually bent by the operator in accordance with the side plate 50.

That is, since the flanges 53 protrude from both ends of the upper and lower plates 51 and 52, and the second core 56, which is a portion in which the first core 55 is fitted, is formed at both ends. In general, the upper and lower plates 51 and 52 are bent by hand by being unable to be bent by an apparatus consisting of three rollers used to bend a duct.

Here, the upper and lower plates 51 and 52 in which the upper and lower plates 51 and 52 of the duct on which the flange 53 is formed cannot be introduced into the apparatus as described above, and the second core 56 is formed between the three rollers. Injecting the second core 56 is pressed, so that the first core 55 cannot be fitted at the time of assembly, so that the above apparatus cannot be used.

However, as described above, when the upper and lower plates of the duct formed with the flange and the second core portion are manually bent and the side plates are combined, not only about 2-3 workers are required to bend the pipe but also the upper and lower plates are bent by the operator. Therefore, there is a problem that the shape of the curved tube is very irregular.

In addition, bending the upper and lower plates in accordance with the side plate produced with a predetermined curvature in advance makes the work of joining the first and second cores very inconvenient, and the accuracy of the joining portion is reduced, resulting in deterioration of overall assembly, quality and appearance of the duct. There is a problem.

Accordingly, an object of the present invention is to solve the above problems, and when forming the upper and lower plates of the duct with the flange and the core portion formed with curvature, while forming the upper and lower plates of the curved pipe while preventing the work efficiency degradation and the quality of the curved pipe by manual operation An object of the present invention is to provide a bend curvature manufacturing apparatus for a shim type duct with a flange formed so as not to be pressed.

In order to realize the above object, the present invention is installed on the upper portion of the base and is installed upright on both sides of the base, and is installed so as to rotate between the vertical plate and the surface portion of the upper and lower duct plate is fixed A first forming roller having a plurality of first receiving portions formed therein so as to protrude from the first supporting portion at intervals and a plurality of first receiving portions inserted therein; A second molding roller formed such that the core portion is not pressed, a third molding roller spaced apart from the first and second molding rollers so as to apply a predetermined curvature to the upper and lower plates passing through the first and second molding rollers, and the upper and lower plates. To insert the flange formed between the first and second forming rollers, to raise the second forming roller and to lower it when bending. The lift generated by means, operable to configure them in the above-described the first and second forming rollers in close contact state with the driving means is provided to rotate interlocking.

The first and second forming rollers 5 and 8 and the third forming roller 9 are provided to be spaced apart from each other so as to apply a predetermined curvature to 2).

That is, even if the upper and lower plates 51 and 52 having the second core portion 56 formed therebetween pass through the first and second forming rollers 5 and 8, the second core portion 56 may be formed without curvature. The first and second storage parts 4 and 6 and the support parts 3 and 7 formed in the first and second molding rollers 5 and 8 are alternately formed to form a top plate when forming a curved pipe. Since the bending directions of the 51 and the lower plate 52 are opposite to each other, the curvature forming operation of the upper plate 51 and the lower plate 52 can be performed in one step.

Of course, if only one of the first and second forming rollers 5 and 8 forms the support part and the receiving part, the upper plate 51 or the lower plate 52 can only be curvature-molded one by one, resulting in a very low work efficiency. One machine is required for forming the 51 and the lower plate 52, respectively.

In addition, the first and second forming rollers 5 and 8 are rotated at a predetermined speed by a driving means, which is a motor 10 fixed to the lower part of the base 1 and the motor 10.

In particular, the second forming roller 8 is configured to be liftable by lifting means, which means that the lifting means is provided with a flange 53 formed on the upper and lower plates 51 and 52 of the duct. When inserting between the two shaping rollers 5 and 8, the 2nd shaping roller 8 is raised and lowered during curvature processing.

As shown in Figs. 4 and 5, the elevating means is inserted into the vertical moving hole 16 perpendicular to the vertical plate 2, and the vertical moving hole 16 is inserted into the vertical moving hole 16 The elevating block 17 configured to be rotatable while being guided by the elbow and supported at both ends of the second forming roller 8 by a bearing or the like, and the cylinder rod R at the upper end of the elevating block 17. Is connected and consists of a cylinder 18 fixedly installed on top of the vertical plate 2.

In particular, the guide block 19 is fixed to the outer surface of the elevating block 17 in order to adjust the height of the elevating block 17, and screwed vertically to both ends of the guide block 19, the height An adjustable stop bolt 20 and a stopper 21 for limiting the lowered position while contacting the stop bolt 20 when the lifting block 17 is lowered are provided. Rotate to adjust the height can be adjusted.

Of course, when the lifting block 17 is raised, the first and second forming rollers 5 and 8 are spaced apart, so that the flange 53 of the duct can be easily passed, and when the first and second gears are lowered, 14, 15) to be engaged.

The third forming roller 9 is installed by the moving means so as to be movable in the horizontal direction so as to adjust the curvature of the duct, as shown in FIG. 6 on the vertical plates 2 on both sides. Moving blocks which are inserted into the horizontal moving holes 22 and the horizontal moving holes 22 on both sides, which are formed so as to move, and both ends of the third molding roller 9 are supported by a bearing or the like to rotate and move. 23, the groove 24 formed at one end of the moving block 23, and the nut 25 is fixed to the end in order to be freely rotatable in the groove 24 and to the vertical plate (2) Screw 26 and the handle 27 installed in the screw 26 and the screw 26 to reciprocate with the moving block 23 during rotation, and the moving block 23 so that the nut 25 does not fall into the groove 24 ) To the fixing plate 28 and the two screws 26 described above. Provided by the third sprockets 29 and connecting them consists of a chain 30, which rotates interlocking.

In particular, a power means is installed to transmit power when the third molding roller 9 moves, and as shown in FIG. 2, a fourth sprocket (1) is installed at one end of the first molding roller 5. 31), an idle sprocket 32 installed on the vertical plate 2 so as to correspond to the fourth sprocket 31, a fifth sprocket 33 provided at one end of the third forming roller 9, It consists of a chain 34 connecting the fourth and fifth sprockets 31 and 33 and the idle sprocket 32, so that the fifth sprocket 33 moves in a horizontal state so that power is transmitted even when it is moved. This is done smoothly.

Referring to the operation and effect of the present invention as described above, as shown in Figure 7a to operate the cylinder 18 to raise the elevating block 17, as well as to raise the second forming roller 8 installed therein. .

The second molding roller 8 is raised, and the handle 27 is rotated to move the moving block 23 and the third molding roller 9 installed therein so that the rollers 5, 8, 9), the upper plate 51 and the lower plate 52 on which the flange 53 is formed are inserted between the first and second forming rollers 5 and 8.

When the upper plate 51 and the lower plate 52 are introduced between the first and second forming rollers 5 and 8 together, the upper plate 51 and the lower plate 52 of the duct are simultaneously formed, thereby maintaining a constant curvature. I can make it.

When the upper plate 51 and the lower plate 52 are inserted between the first and second forming rollers 5 and 8, the second forming roller 8 is lowered as shown in FIG. 7B, and the third forming roller 9 is moved. When the first and second forming rollers 5 and 8 are brought into close contact with each other, the first and second supporting parts 3 and 7 come into contact with each other as illustrated in FIGS. 8 and 9. 51 and the surface part of the lower board 52 are pressed, and the 1st, 2nd storage part 4 and 6 are in the state which accommodated the 2nd core part 56. As shown in FIG.

When the motor 10 is operated in this state, the first gear 14 is rotated by the chain 12 and the first and second sprockets 11 and 13, and the second installed in the second molding roller 8. Since the gear 15 is engaged with the first gear 14, the second forming roller 8 rotates in a direction opposite to the first forming roller 5.

In addition, since the fifth sprocket 33 installed on the third molding roller 9 is connected to the fourth sprocket 31 provided on the other end of the first molding roller 5 by the chain 34, The forming roller 9 also rotates at the same speed.

As described above, when the first, second, and third molding rollers 5, 8, and 9 rotate at the same speed and rotate in the direction pushing the upper plate 51 and the lower plate 52, the upper plate 51 and the lower plate ( 52 is automatically molded to a predetermined curvature.

At this time, the upper plate 51 and the lower plate 52 inserted between the first and second forming rollers 5 and 8 are inserted in opposite directions, respectively, which is upper and lower plate 51 and lower plate when forming the curved pipe. This is because the bending direction of 52 is reversed.

When the upper plate 51 and the lower plate 52 are molded to a predetermined curvature by the rotation of the first, second and third forming rollers 5, 8 and 9, the second core 56 and the flange 53 are affected. It is formed without the bar, because the molding by the roller can be molded with a very uniform curvature and the work can be completed in a short time.

When the upper plate 51 and the lower plate 52 are formed to have a predetermined curvature, the upper plate 51 and the lower plate 52 are connected to the side plate 50 of the curved pipe that is previously formed, and the first core 55 and the upper and lower plates 51 and 52 of the side plate 50 are formed. The second core 56 of the) is combined to produce a curved pipe.

In this case, in order to change the curvature of the curved pipe, the horizontal position of the third molding roller 9 is changed by rotating the handle 27. When the handle 27 is rotated, the chain 30 is rotated. The two screws 26 connected to the third sprocket 29 rotate together and reciprocate, and the moving block 23 connected thereto reciprocates in the horizontal movement hole 22, whereby the third molding roller 9 ) Position is changed to change the curvature of the duct.

As described above, the present invention enables the fabrication of the curved pipe of the duct, which is formed with a flange and is coupled to the core, without manufacturing by hand, so that it can be manufactured quickly and uniformly by a molding roller, thereby improving the efficiency of manufacturing the pipe of the duct and unnecessary operator's need. There is an advantage to prevent waste.
