The technical field to which the invention relates.

The present invention relates to a device and method of manufacturing the spiral duct, more particularly, to a device and method of manufacturing the spiral curved duct, in which the straight line connecting the boxes are combined into one unit with both ends of the curved box that allows you to securely connect the bent section formed at the straight edge, with a folded section formed on a wavy edge that prevents the release of unsuitable products by ensuring smooth cutting metal strip through a wavy line in the longitudinal direction.

The level of technology

Curved duct, in which the band-shaped metal plate is twisted into a spiral shape, and the side edges of the metal plates which engage and are fastened to each other, is disclosed in Japanese patent publications No. S59-27478 and S63-50595.

However, as known from the prior art solutions, the metal strip is continuously cut to form parts of large width and details of small width, and then dumped the remains, the metal tape is wasted.

To prevent waste of material, available in Korean patent publication No. 1990-17678 offers"Metal tape for making spiral duct, shown in figure 1.

Namely, a single sheet metal strip is cut into two metal tapes, each of which has areas of greater width and areas of lesser width are alternately formed in its longitudinal direction. That is, each metal strip has one straight side edge and the other wavy side edge, reducing, thus, the waste metal tape to a minimum.

Using one or two metal strips on the straight side edge of the formed double-curved element, and the wavy lateral edge in the vertical direction along the entire length is formed by a single curved element. Metal tape is twisted into a spiral; at the same time the area of greater width is located on the outer curved section, and a portion of less width is located on the inner curved section. Further, the adjacent single curved element and double-curved element sequentially injected into each other, and then to finish the curved duct, pressed.

Figure 2 shows a conventional device for manufacturing a curved duct.

As shown in the drawing, the metal strip 3 is extended between the first forming rollers 11 of the device for manufacturing a curved duct so as to form on the L-shaped bent element 4 on both edges of the metal strip 3.

Then L-shaped bent elements 4 are bent again using a pair of upper and lower forming rollers 14 located in front of the first roller 11 so as to form an almost C-shaped double curved elements 5.

Next, as shown in figure 3, the metal strip 3 having a double-curved elements 5, is cut and divided by nesting roller 18 having a wavy groove 17 formed on its outer periphery (roller diameter the same as the curved duct), as well as incoming roller 20, which has a wavy blade 19, the corresponding wave trough 17.

In addition, at the same time, the metal strip 3 is cut; both cut edges wavy blade 19 are pushed into the chute 17 so as to form a L-shaped profiles, thus creating a single pair of curved elements 6.

Further, as shown in figure 4, a single curved elements 6 two metal strips 2 are bent in the direction of the double-curved elements 5 through located in the front upper support roller 21, and third lower forming roller 25, with almost a diamond shape and supported in the axial direction of the bearing 24 of the slide 23, worn by slipping on a horizontal drive shaft 22.

Below is a description of the operation of the apparatus for manufacturing spiral duct in accordance with the exemplary embodiment of the present invention.

First on the forming rollers serves the metal strip 300, wound on the coil 700 in the form of a roll.

All metal strip 300 extends through the first forming roller 111 tilt.

Then the metal tape 300 passes through the second forming roller 112 tilt, so that the two straight edges of the metal tape thibaudia down.

Then the metal tape 300 passes through the third forming roller 113 tilt, so bent down straight edges of the metal tape is thibaudia up for the formation of the convex elements in the form of double-curved elements 310.

After that, the metal strip 300 that passes through the third forming roller 113 slope, passes through the marking rollers 210 for applying a marking on the bottom surface of the metal strip 300 in the form of wavy lines. At this point, the rotation angle of marking rollers 210 should be changed periodically in a horizontal direction.

Then inclined straight edges of the metal strip passes through the forming rollers 120 a vertical section to form a vertically bent section.

In addition, the metal strip passes through the separating rollers 220 to change the horizontal angle of rotation for cutting along a wavy line and separation of the metal tape on the two cut metal tape. At the same time the metal tape is cut in a wavy line, wavy edges are formed by single curved elements having the form "the".

Next vertically oriented sections of the two curved edges of the metal strip is additionally bent inwards through the forming rollers 130 of the inner slope.

Then the wavy edges of the metal strip 300 pass through the second komkoobrazuyuschih rollers 400 to be formed in the convex single curved elements 320.

Further divided metal bands go through to rawaudio rollers 600, and each of the two shot the metal strips served in edging device 500 to uncoil metal strip, fasten a single curved element 320 and double-curved element 310, and then compress them into the connection points for the formation of durable duct.

Moreover, as shown in figa and 17B, when the cutting rollers are parallel to the metal strip on the site of the injection and the site of the end of the metal strip to cut the metal strip into two rectilinear parts, and then twist each cut the metal strip, it is possible to make a duct in which a straight line connecting the boxes S formed into a single unit with curved duct C.

As you can see from the above, since the horizontal angle of rotation of the cutting rollers is changed periodically in order to continuously cut the metal strip in straight lines and wavy lines, it is possible to form a duct, in which the straight line connecting the boxes are combined into a single unit with a curved duct.

In addition, it is possible to change the period and amplitude of the wave form, in which the metal strip is cut cutting rollers to freely control the diameter of the duct.

In addition, since the cut coccinellinae tape smoother than provide known solutions, where the blade and the groove formed on the surfaces of the two rollers can be accurately and securely fasten a single curved element with a double-curved element on the parts of their seams.
