Description

Automatic manufacturing device of flexible tube

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic manufacturing apparatus for a flexible tube composed of a tubular body by a coupling in which both ends of a wound member cross each other while spirally winding a band member of a cloth or rubber and an elongated thin plate such as aluminum.

As is well known, flexible is a tube that is free to bend, and its structure is formed by a tubular member of a thin plate, but is formed into a corrugated wave and has a bend of the pipe by a curved shape, or an elongated thin plate Winding the band member pieces in a spiral shape and joining both ends to each other to form a tubular body. The bendability of the thin plate member allows the tube to be bent freely by the flexible member of the tube and the flexibility of the band member and the connecting member. Due to this free bending feature, flexible pipes are used in many fields such as duct dust absorption and exhaust pipe range hood exhaust pipe of buildings.

In particular, the present invention relates to a flexible tube formed by pressing and fastening both ends with a fastening member while winding an aluminum thin plate in a threaded shape.

Such flexible pipes are used in many fields such as duct pipes, hoses and air supply pipes of buildings due to free bendability as described above, and their preferences are increasing.

Flexible tube of this feature is wound in the wire strip of the aluminum band member of the thin plate as shown in the Republic of Korea Utility Model Publication No. 1997, No. 1997, in the form of a screw thread when the both ends overlap and heat-sealed Maintaining the tubular shape and the flexibility of the thin aluminum to bend freely, and the high temperature by the aluminum material and the use of the iron wire in many uses and folding the round tube into the plate shape to reduce the volume or convenience of storage and movement so as to obtain I've done it.

On the contrary, flexible tubes having elasticity in length while preventing the tube from being crushed by forming a tube by squeezing both ends of the thin plate member with a fastening member of a metal while winding the aluminum strip member of the thin plate with a screw line are known.

Such flexible pipes are used as air pipes in ducts and workplaces, and are becoming preferred in many fields such as heat discharge tubes.

Another flexible tube is press-bonding a non-flammable fabric to the strip member of the aluminum sheet and its back side, so that the aluminum sheet is more firm and fire resistant.

However, the flexible tube formed of the aluminum thin plate member and the metal member is not developed in Korea, so it is dependent on imports.

These importers are mainly importing the devices of Japanese international groups, but their prices are high and they do not disclose the substance with limited imports.

The present invention is to provide a domestic apparatus for producing a flexible tube that has been used a lot.

And the connection member 100 and the belt member 200 which are pivoted by the second pressing roll 42-1 formed on the outer circumferential surface of the forming roll 41 may be continuously connected to each other to form a tubular body. 11 is shown as another embodiment as a connecting member bending device to constitute a vertical rolling roll bending device 50 but the lower rolling roll 51 to form a bending groove 13 and the upper rolling roll 52 In forming the pressing portion 53 and by configuring the roll means step by step to form a bending angle sequentially.

Reference numeral 60 is a pressing dolte of the pressure roll, 61 is a pressure roll conveying device, 62 is a guide roll.

The effect of this invention comprised in this way is demonstrated.

1 is a front view showing the whole of the present invention as shown in the construction of the metal connecting member 100 and the base 1, which constitutes a flat strip member supply device 11, such as aluminum or textile paper, The connection member winding device 10, the band member bending device 30 and the insertion guide 20 and the pressure roll device 40 in the present invention consisting of a guide member in order to the winding winding as shown in FIG. The gas is operated by supplying the member 100 and the band member 200.

When the members supplied by the plate-like member is introduced into the C-shaped bending groove 13 formed on the outer circumferential surface of the bending roll 12 of the connecting member bending device 10 as shown in Fig. By 13 Both ends are bent in a shape to be transferred to the guide guide (21).

The bending roll 12 is of course driven by a power motor and a reducer.

The connection member 100 bent by the above is conveyed along the conveying hole 22 of the guide guide 21, and is supplied by the band member supply device 11 formed in the upper body 1 of the guide guide 21. The band member 200 is supplied to the upper end of the connecting member 100 and introduced into the bending roller 31 of the band member bending device 30 hinged to the guide guide 21.

At this time, the supplied band member 200 is formed larger than the width of the bending roller 31, so that both side portions of the band member 200 are bent downward by the bending ring piece 32 of the bending roller 31 and the guide guide 21. By the conveying hole 22 and the guide hole 23 formed in the The bent piece 201 bent in a shape is formed and conveyed together with the connecting member.

However, in the conveying hole 22 of the guide guide 21, the bent connecting member 100 is already positioned and the bent piece 201 is opened by the opening 102 formed in the member. It is conveyed in the inserted state. As such, when the bent piece 201 of the belt member 200 is inserted into the opening 102 of the connecting member 100 and moved, the first insertion piece protruding from the fastening plate 25 as shown in FIG. The bent piece 201 is inserted into the fixing piece 101 of the outer side, that is, the fixing piece 101 of the connecting member 100, so that the bending piece 201 is positioned inside the fixing piece 104 and is conveyed.

The members to be conveyed as described above are positioned on the inner side of the fixing piece 101 while being pressed along the outer circumferential surface of the forming roll 41 as shown in FIG. 6 by the first pressing roll 42. The bending piece 201 of the belt member 200 is press-coupled to the connection member 100.

The combined members rotating along the forming roll 41 by fixing the band member 200 to one side of the connecting member 100 are transferred to the lower part of the guide guide 21 to pass through the upper part of the forming roll 41.

Then, another bending piece 201 of the belt member 200 which is conveyed along the guide hole 23 of the guide guide 21 is moved under the forming roll 41. The bending piece 201 which is moved in accordance with the opening 102 of the connecting member 100 is inserted into the opening 102 of the connecting member and is transferred.

At this time, the second insertion piece 26-1 fixed to the guide guide 21 at the position where the connection member 100 passes is located at the opening 102 of the connection member 100, and thus, the first insertion piece. As in (26), the bent piece 201 of the strip member inserted into the opening 102 is pushed into the fixing piece 101 of the connecting member like the first insert piece 26.

Accordingly, the fixed piece 101 to be conveyed is pressed by the second pressing roll 42-1 formed on the outer circumferential surface of the forming roll 41 to fix the band member 200 at the inner side, as shown in FIGS. 9 and 10. As described above, the belt member 200 is continuously connected to both sides of the connection member 100 to form a spiral tube.

And Figure 11 shows the bending means of the fixing piece 101 of the connecting member 100 for fastening and connecting the band member 200 of the present invention constitutes a vertical rolling roll bending device 50, the lower rolling roll 51 The bending groove 13 is formed in the upper rolling roll 52, and the pressing portion 53 is formed, and the roll means are configured step by step to form a bending angle sequentially. Step by step implementation has the advantage that can be performed more precisely bending and bending state with a small force.
