Description

Reinforcement Duct Manufacturing Equipment

The present invention relates to an apparatus for manufacturing a reinforcing duct, and it is possible to selectively manufacture a duct with a groove and a duct without a groove by using a single manufacturing apparatus, so that the plate material can be supplied without being pushed and not crushed when forming the tube It relates to an apparatus for manufacturing a reinforcing duct that can have a uniform surface shape, whether with grooves or not, and can retain deformation resistance against external loads and vibrations.

More specifically, the apparatus for manufacturing a reinforcing duct of the present invention sequentially arranges a groove forming part for forming a groove and a carving part for forming a comb pattern, and includes hydraulic cylinders on both sides of the lower roller of each of the groove forming part and the carving part. The process of forming a groove or knurling a comb pattern by separating or closely adjusting the upper and lower rollers of the groove forming part and the upper and lower rollers of the carving part by connecting them and keeping each lower roller horizontally and moving up and down in a single manufacturing process It can be selectively applied as a device, but it is a method of manufacturing a reinforcing duct that can improve the feeding ability of plate materials and simultaneously improve strength and appearance by creating a uniformly patterned surface regardless of whether or not grooves are formed. It's about the device.

In general, a duct is installed in a building as a passage for moving air for ventilation and ventilation. Usually, a tin plate is processed to form a straight pipe body.

However, the conventional duct formed of a conventional tube body has no foldability and flexibility, and has a large volume, so it is very difficult to manufacture and transport as well as construction work.

In order to solve this problem, a duct made in the form of a foldable bellows has been proposed, which is manufactured in the form of a spiral corrugated pipe by bonding a nonwoven fabric and aluminum fabric to a spirally formed iron piece.

However, in the duct using the adhesive, harmful substances are generated from the adhesive, so there is a problem that the working environment is polluted and the health of the worker is harmed. There was a problem that the lifespan was shortened due to falling.

To improve this, a method of producing a duct having a single tubular shape by bending both side ends of a metal plate in opposite directions has been developed and used to interconnect the bent parts while winding in a spiral.

However, in this case, there is a problem in that the overall rigidity is lowered, so a method of increasing the strength by forming a groove on the surface of the duct is used. This increase causes difficulties, is uneconomical, and causes inefficiencies in the work process.

In addition, when a device that forms a groove in a duct and a device that does not form a groove share the latter part of forming a tube body, the duct without a groove has a uniform and uniform surface pattern, which reduces the aesthetic aspect. Problems are occurring.

In this case, the feeding lower roll 420 is in a state in which the feeding upper roll 410 and the plate are engaged with the feeding upper roll 410, the rotational force of the It can be rotated by interlocking with it.

All of the lower feeding gears 421 included in the description below may be selectively configured in the feeding unit 400 or may be optional.

The feeding lifting plate 426 may be provided in a shape similar to the above-described carving lifting plate 325 .

That is, the feeding lifting plate 426 is coupled to both ends of the rotating shaft connecting the feeding lower roll 420 and the feeding lower gear 421, and the feeding lifting plate 426 is fixed, and the rotating shaft can rotate. , may be mounted on the lower portion of the feeding unit 400 of the frame 20, and its shape may be configured in a manner similar to that of the above-described carving plate 325.

That is, openings may be provided in the lower portions of both sides of the frame 20 at positions corresponding to the lower feeding rolls 420 , respectively, and the feeding lifting plates 426 are mounted in the openings to cover the openings, but feeding the lifting plates 426 . ) may be provided in a shape of pinching the edge of the opening of the frame 20 by forming a recess in a 'C' shape.

Accordingly, the frame 20 may serve as a guide to enable the feeding elevator plate 426 to move up and down along the recess in a pinched state with the feeding elevator plate 426 .

A plurality of feeding hydraulic cylinders 422 are provided, respectively, mounted on the lower portion of the feeding lifting plate 426 , and the plurality of feeding lifting plates 426 may be simultaneously raised and moved from both sides.

When the feeding lifting plate 426 is moved up and down, the feeding lower roll 420 and the feeding lower gear 421 connected by the same rotation axis as the feeding lifting plate 426 can also be moved up and down while maintaining the horizontal.

The feeding hydraulic distributor 423 may be provided to receive hydraulic pressure from the feeding hydraulic pump 424 and distribute the same hydraulic pressure to the plurality of feeding hydraulic cylinders 422 .

As a result, the feeding hydraulic cylinder 422 moves the feeding lifting plate 426 up and down, but by the same hydraulic pressure at both ends, the cylinder operates so that the raising and lowering are performed while maintaining the horizontal level, so that the feeding lifting plate 426 is horizontal without being inclined It is possible to smoothly move up and down while maintaining the , so that the lower feeding roll 420 and the lower feeding gear 421 are horizontally maintained in the lower part of the feeding unit 400 and can be moved up and down smoothly.

Accordingly, even if the lifting and lowering movement of the feeding lower roll 420 is repeated a number of times according to the selection of the manufacturing process, it can be a feature that can accurately and stably maintain a horizontal state.

Therefore, when the feeding lower roll 420 rises according to the lifting operation of the feeding hydraulic cylinder 422, a gap is formed at a predetermined interval to correspond to the thickness of the feeding upper roll 410 and the plate material P, and it is kept in close contact. location can be

Conversely, when the feeding lower roll 420 descends according to the lowering operation of the feeding hydraulic cylinder 422, the feeding upper roll 410 and the plate material P may be spaced apart by a distance exceeding the thickness.

However, the feeding lower roll 420 does not move down by the duct manufacturing process in the reinforcing duct manufacturing apparatus 10 of the present invention, and may be arranged by descending for additional purposes other than the manufacturing process, such as maintenance or cleaning. .

That is, the lower feeding roll 420 may be configured to always maintain a position in close contact with the lower feeding roll 420 in the manufacturing process.

Meanwhile, the feeding hydraulic pump 424 and the carving hydraulic pump 324 may be connected to the same hydraulic tank 600 to receive hydraulic pressure.

The operations of the groove forming unit 200 , the carving unit 300 , and the feeding unit 400 are briefly summarized as follows based on the above description.

First, if you want to configure the reinforcing groove (G) in the plate material (P), the groove forming part 200 is in close contact with the reinforcing groove on the surface of the plate material (P) by the processing protrusion 211 of the upper groove roll 210. (G) is processed, the carving part 300 is spaced apart to pass the plate material P, and the feeding part 400 knurls the comb shape on the surface of the plate material P while maintaining a close contact state. have.

On the other hand, if you do not want to configure the reinforcing groove (G) in the plate (P), the groove forming part (200) is spaced apart to just pass the plate (P), and the carving part (300) is in close contact with the plate (P). A comb pattern is generated on the surface and supplied to the feeding unit 400, and the feeding unit 400 knurls the comb pattern on the surface of the plate material (P), but the comb pattern shape is already provided on the surface of the plate material (P). Therefore, there is no difference from the existing state, and it can be moved as if it were just passed.

The comb pattern formed on the surface of the plate (P) may have an effect of moving the plate (P), and the reinforcing groove (G) may have deformation resistance against external load and vibration of the duct.

A comb-shaped bead is formed on the outer circumferential surface of the feeding upper roll 410 so that the plate material P can be pushed while gently pressing, and the feeding unit 400 supplies the plate material P to the tubular body forming unit 500, which is a subsequent process. However, it may have the advantage of allowing the plate material P to be accurately supplied without being pushed.

At this time, if the feeding upper roll 410 is flat without a comb pattern bead on the outer circumferential surface, it is not possible to push the plate material P in a tight state when transporting it, and sliding and crushing may occur. In this case, the tubular type Since it is difficult to quantitatively supply the plate material P to the cast part 500 at a constant speed, an error may occur in the tubular body forming process.

The tubular body forming part 500 is located at the tip of the feeding part 400 and may function to form a helical tubular body and cut the plate material P transferred from the feeding part 400 into a predetermined length.

The tube body forming part 500 connects the connecting grooves L1 and L2 created on the edge of the plate P in the groove forming part 200 while spirally winding the plate material P to each other with a lock seam. It is possible to make a duct of a shape, and when the duct is formed to a predetermined length set in advance, the tube body can be cut by a cutting member to complete the manufacture of the duct.

At this time, the reinforcing groove (G) may or may not be configured on the surface of the plate material (P) of the reinforcing duct of the present invention. , a comb pattern may be formed on the surface of the plate material P regardless of the presence or absence of the reinforcing groove G.

Based on the above description, an example of use of the reinforcing duct manufacturing apparatus 10 according to a preferred embodiment of the present invention will be described as follows.

The thin metal plate material P to be manufactured as a duct moves through the supply unit 100 , the groove forming unit 200 , the carving unit 300 , and the feeding unit 400 in order, and in the tube body forming unit 500 , the duct At least one reinforcing groove (G) may be created on the surface of the duct in this process, and as the connection grooves (L1, L2) created on the edge of the duct are combined, the spiral-shaped tube body may be formed, and a comb-shaped knurling may be processed on the surface of the duct.

First, the supply unit 100 unwinds the plate material P wound on the take-up reel 110 and inserts it into the connection groove processing roll 120, and an unfolding process is performed. Connection grooves L1 and L2 may be formed in the .

The plate material P is transferred from the supply unit 100 to the groove forming unit 200 .

In the groove forming part 200 , at least one reinforcing groove G may be formed on the surface of the plate P by the processing protrusion 211 provided on the outer peripheral surface of the grooved roll 210 .

The reinforcing groove (G) can function to have deformation resistance against external loads and vibrations after the duct is installed by increasing the strength of the duct and improving the vibration absorption force applied to the duct.

In this case, the formation of the reinforcing groove (G) on the surface of the plate (P) in the groove forming portion (200) may be optionally carried out.

Therefore, if you want to form the reinforcing groove (G), the upper grooved roll 210 and the lower grooved roll 220 are spaced apart only by a gap corresponding to the thickness of the plate material (P) and positioned so that they can be in close contact with each other. .

On the other hand, if you do not want to form the reinforcing groove (G), lift the groove hydraulic cylinder 213 to move the lifting plate 212 upward to raise the groove upper roll 210 to transport the plate material (P). P) It can be positioned so that it is not pressurized on the surface.

At this time, the lower groove roll 220 transfers the plate material P to the carving unit 300 , which is a subsequent process, in a fixed state.

The carving unit 300 forms a predetermined gap between the carving upper roll 310 and the carving lower roll 320 in a fixed position, and is in close contact with each other to accommodate the inlet of the plate material P.

A comb-shaped bead is formed on the upper carving roll 310 and provided, and the lower-carving lower roll 320 may be provided with or without a comb-shaped bead.

The upper carving roll 310 and the lower carving roll 320 pressurize the surface of the plate material P while rotating and simultaneously transfer, and at this time, a comb-shaped bead provided on the outer circumferential surface of the carving upper roll 310 . Due to this, it is possible to feed while strongly engaging the plate material (P), and due to this, a comb pattern may be knurled on the surface of the plate material (P).

In the carving part 300 , similarly to the groove forming part 200 , knurling of a comb pattern may be selectively performed.

If you want to knurl the comb pattern on the surface of the plate (P), it is enough to accommodate and pressurize the inlet of the plate (P) in a close contact with the upper carving roll 310 and the lower carving roll 320 positioned in place.

On the other hand, if you do not want to engrave the comb pattern on the surface of the plate (P), lower the carving hydraulic cylinder 322 to lower the carving lifting plate 325 and lower the carving lower gear 321 and the lower carving roll 320. By moving the carving upper roll 310 to be spaced apart from the plate material P by more than the thickness, it can be arranged so that it cannot be pressed on the surface of the plate material P.

At this time, if the reinforcing groove (G) is formed on the surface of the plate material (P) in the groove forming part (200), the carving part (300) must be provided so as not to knurl the reinforcing groove (G) to be transferred to the subsequent process without being damaged. Therefore, if the groove forming part 200 is configured in close contact, the carving part 300 should be spaced apart.

Similarly, if the groove forming portion 200 is configured to be spaced apart so that the reinforcing groove G is not formed, the carving portion 300 should be able to be configured in close contact.

The plate material P passing through the groove forming part 200 and the carving part 300 may be in one of two forms.

One is a state in which the reinforcing groove (G) is formed on the surface of the plate material (P) and there is no comb pattern, and the other one may be in a state in which there is no reinforcing groove (G) and there is a comb pattern.

The former is manufactured through a process in which the groove forming part 200 is in close contact and the carving part 300 is spaced apart, and the latter is manufactured in a state in which the groove forming part 200 is spaced apart and the carving part 300 is in close contact. Thus, the plate material P may be introduced into the feeding unit 400 in one of the former and the latter two forms.

The feeding unit 400 passes through the groove forming unit 200 and the carving unit 300 and transfers the plate material P with the reinforcement groove G or the comb pattern formed thereon to the tube body forming unit 500, which is a subsequent process. can do.

The feeding upper roll 410 is provided with the same comb-shaped bead as the carving upper roll 310, and the feeding lower roll 420 may be provided without the comb-tooth pattern being formed.

The feeding part 400 can feed the plate material P by strongly engaging the plate P due to the comb-shaped bead provided on the outer peripheral surface of the feeding upper roll 410, so that the plate material P has a knurled comb pattern on the surface. can

However, the feeding lower roll 420 may be provided with a feeding groove 425 in a shape and position corresponding to the reinforcing groove (G), and thus the reinforcing groove (G) is provided on the surface of the plate (P) and reinforced when it is transported. The groove (G) is accommodated in the feeding groove (425) and can pass through the feeding portion (400), so that the reinforcement groove (G) is not damaged.

After all, if the reinforcing groove (G) is formed in the plate (P) in the groove forming part (200), the plate (P) passes through the spaced carving part (300), a comb pattern is not generated and the reinforcing groove (G) is not damaged. It passes through the feeding unit 400 in a non-destructive state, and the reinforcing groove (G) is maintained in an undamaged state after the passage, but a comb pattern may be generated.

On the other hand, if the reinforcing groove (G) is not formed in the plate (P) in the groove forming part (200), the plate (P) passes through the closely-contacted carving part (300) and a comb pattern is generated, and then the feeding part (400) The same comb pattern is pressed while passing, but since it is an already formed comb pattern, it can pass through the feeding unit 400 without a separate influence.

In any case, the plate material P after the process of the feeding unit 400 has been completed may be in a state knurled in a comb pattern on the surface, but may or may not be provided with a reinforcing groove G. .

Therefore, it is possible to remove the factors that inhibit the appearance of the surface condition is different depending on the case where the reinforcing groove (G) is provided and the case where the reinforcing groove (G) is not provided as in the conventional duct manufacturing apparatus, and the reinforcing groove (G) is Even if it is not provided, it is possible to retain deformation resistance against external loads and vibrations due to the comb pattern.

The appearance impeding factor may include a case in which a groove is formed as shown in FIG. 6 , wherein the groove in FIG. 6 is a plate material (P) when a reinforcing groove (G) is not formed in the conventional duct manufacturing apparatus. ), an unintentional stripe is not generated in the corresponding portion of the feeding groove 425 , which means that it is misunderstood as a flaw caused by a process error, and the preference is lowered due to an uneven appearance.

Due to this, there were difficulties in the field in which sales were difficult due to being mistaken for a defect in the product even though it was a normal product. Through the strong feeding force of the roll 310 and the feeding upper roll 410, it has the ability to constantly supply the plate material P without being pushed, and at the same time, a uniform comb pattern is formed on the surface, thereby solving the above problems. It can be a solution to overcome.

The tubular body forming unit 500 makes a tubular duct by connecting the connecting grooves L1 and L2 with a lock seam while spirally winding the plate P transferred from the feeding unit 400, and the duct of a predetermined length is set in advance. When formed, it is possible to finish all the processes of the reinforcing duct manufacturing apparatus 10 of the present invention by cutting.

On the other hand, if a foreign material is caught in the feeding unit 400 or a situation requiring maintenance occurs, the feeding hydraulic cylinder 422 is lowered to move the feeding lower gear 421 and the feeding lower roll 420 to the lower side. can take

Similarly, in the case of maintenance, cleaning, etc. in the groove forming unit 200 and the carving unit 300 , related measures may be taken through the upward movement of the grooved upper roll 210 and the downward movement of the carving downward roll 320 .

The embodiments of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and equivalent other embodiments are possible therefrom.

Therefore, it will be well understood that the present invention is not limited to the form mentioned in the above detailed description. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
