The present invention relates to an apparatus for manufacturing a multi-ply corrugated pipe.

Corrugated pipe is formed to corrugate the plate member to be used for the purpose of absorbing vibration in the pipe, cushioning, preventing noise, expansion and contraction by thermal deformation, and reducing the expansion and noise by connecting to the muffler pipe of the vehicle.

In addition, it is also used for power transmission capable of transmitting torque with relatively low rotational force. In recent years, at least two or more members are formed to overlap each other depending on the use thereof, and thus the elastic absorption and noise reduction caused by heat or vibration, and The situation is demanded to have a great effect of the dust.

In the apparatus for producing such corrugated pipes, conventionally, the hollow cylindrical member is placed in a mold having a corrugation formed therein by a method of embossing by placing a hollow cylindrical member with a predetermined thickness and applying pressure by hydraulic pressure therein.

Therefore, according to this process, when the corrugated pipe is molded into only one layer of member, there is no difficulty in manufacturing the corrugated pipe in its own way, but it is impossible to manufacture a multi-ply corrugated pipe of two or more layers.

An object of the present invention is to provide a multi-ply corrugated pipe manufacturing apparatus that can be more easily and continuously produced a multi-ply multi-ply corrugated pipe.

Another object of the present invention is to provide an apparatus for manufacturing a multi-ply corrugated pipe, which is capable of improving the quality of the corrugated pipe and extending its life.

Another object of the present invention is to provide a multi-ply corrugated pipe manufacturing apparatus that can be automatically cut to the appropriate length according to the application after forming the corrugated pipe.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention provides a pair of upper and lower forming rollers (13) and (14) with a number of wrinkles in consideration of the thickness of the corrugated pipe that is supplied from the bobbin 11 wound around the plate member 12 having a recognized thickness and width. Plate-forming portion 10 for molding the corrugated plate 15; The guide portion 20 for guiding movement of the corrugated plate 15 formed by the plate forming portion 10 to guides of the guide rollers 22 provided on both sides of the base 21, and the guide portion 20 It is located on the bottom surface of the corrugated plate 15 to be supplied and provided with a fixed roller 31 and a moving roller 32 having a corrugation shape and pitch corresponding to the corrugated plate 15, and the fixed roller 31 and It forms a spiral along the upper surface of the moving roller 32 and is located inside the corrugated pipe 1 wound to a predetermined diameter, and is provided to the elevating means 50 between the fixed roller 31 and the moving roller 32. Pleated molding portion 30 is provided with a pressure roller 33 for lifting up and down by pressure molding, and the corrugated plate (1) molded in multiple layers with a predetermined diameter in the wrinkle forming portion 30 to the required length The cutting unit 40 is provided with a cutting torch 41 so as to cut the furnace.

The plate forming part 10 is a structural part for molding the plate member 12 into the corrugated pipe 15 along the corrugated curved surface and size to form the corrugated pipe 1.

That is, the plate member 12 wound flat to a certain thickness and width passes between the forming rollers 13 and 14 in multiple stages while being wound on the bobbin 11, as shown in FIG. According to the cross-sectional shape of the finished corrugated pipe (1) is to be molded into a corrugated plate 15 in the form of wrinkles.

The forming rollers 13 and 14 are curved in a pair of up and down so that only one wrinkle is formed in the center at the closest position of the plate member 12 supplied from the bobbin 11. A pair of male shaped rollers 13 and 14 protruding in the circumferential direction of the arm body with the arm body fitted into the groove are positioned, and then two rows of wrinkles are processed to form two corrugations at the next position. The forming rollers 13 and 14, and the forming rollers 13 and 14 in which three to five pleats are formed in the same structure are sequentially installed in a pair of up and down, respectively, and the plate member 12 therebetween. The corrugated pipe 15 is molded by passing through.

At this time, the forming rollers 13 and 14 for each wrinkle shape are completed, if it is difficult to form a complete pleat in one pair of forming rollers 13 and 14 according to the material and thickness selection, it is in an intermediate shape. The preformed forming rollers 13 and 14 for undergoing the deformation process may be installed at a position just before each wrinkle is completely molded.

The molding rollers 13 and 14 are provided with adjustment levers 16 for adjusting the pressing force according to the thickness of the plate member 12 passing through the forming rollers, and the corrugated plate 15 is driven by the driving force of the motor 60. Are rotated in the direction of travel.

FIG. 2 shows the driving means of the forming rollers 13 and 14, and the corrugated pipes are formed by the shafts 62 and 64 decelerated at a predetermined speed in the reduction gear 61 by the driving of the motor 60. Rotate in the direction of 15).

At this time, since the shafts 62 and 64 have different thicknesses from the molding position of the corrugated pipe 15 to be processed, even when it is necessary to adjust the pressing position as necessary during the molding process, the rotational force is transmitted. As a means for this, it is preferable to install the universal joints 63 and 65, respectively, in which the power transmission is performed in a non-linear state.

The guide portion 20 is positioned therebetween to guide the movement of the corrugated plate 15 formed by the plate forming portion 10 to the wrinkle forming portion 30.

Therefore, the guide rollers 22 which are positioned at both sides of the base 21 are guided so that they can be moved to the corrugated part 30 at a proper feed force, as shown in FIG. 1 of the guide roller 22. In order to have a conveying speed and a tension so that the center sag gently between the fixed roller 31 and the moving roller 32 supporting the lower part of the corrugated plate 15 in the corrugated molding part 30 and the upper part thereof. It is preferable to move at a speed at which the corrugated pipe 1 is formed between the pressure rollers 33 for pressing the corrugated plate 15 so as to be moved at an appropriate feed force.

The reason is, in view of the pressing friction force and the feed speed required when the corrugated pipe 1 is molded, the pressing roller for pressing the corrugated plate 15 from the fixed roller 31 and the moving roller 32 and the upper portion thereof. (33) is rotated and in accordance with the conditions for crimping the corrugated pipe (1) to automatically feed at the speed of the bite feed actively without load in an optimal state, to make the diameter of the finished corrugated pipe (1) constant, flat and straight In order to be processed in a smooth state without bending when the wrinkled plate 15 is formed along the spiral wound.

The corrugated portion 30 is a structural portion for processing the corrugated plate 15 formed in the plate forming portion 10 in a plate shape into a corrugated pipe 1 hollowed out circularly along a spiral.

The pleats 30 have a fixed roller 31 and a moving roller 32 positioned below the pleated plate 15 and a pleated plate passing through the top of the fixed roller 31 and the moving roller 32. A press roller 33 is pressed to the upper portion 15.

As shown in FIG. 6, the pressure roller 33 is wound along the direction in which the corrugated pipe 1 is spirally wound by the shaft 72 decelerated at a predetermined speed by the reduction gear 71 by the driving of the motor 70. As shown in FIG. Have a meeting.

At this time, the shaft 72 has a different power transmission position according to the diameter of the corrugated pipe 1 to be processed, and is not in a straight line as a means for transmitting the rotational force even when the position is moved as needed during the molding process. It is good to install each of the universal joint 73 to the power transmission is performed in the refraction section

As shown in FIG. 7, the movable roller 32 rotates the horizontal screw 35 positioned horizontally by the adjustment of the handle 36 and the vertical screw 38 positioned vertically. Moving means for enabling movement is provided.

That is, the horizontal screw 35 is screwed to the holder 34 holding the moving roller 32 so as to move forward and backward by the rotation of the handle 36 and guide the movement of the holder 34. The vertical screw 38 is coupled to the upper portion of the guider 37, so that the upper and lower movements can be made between the support plates 30a by adjusting the handle 39.

Moving the roller 32 back and forth and up and down in this way requires that the fixed roller 31 and its opened position be adjusted differently according to the diameter of the corrugated pipe 1 to be processed, and also to start the first work. At the time, when the corrugated pipe 15 at the leading end to be moved in a straight state is wound in a circular manner, the process of winding in a cylindrical shape by slightly moving the movement roller 32 upward by adjusting the handle 39 is guided. Because it can play a role.

Therefore, the winding operation of the corrugated pipe 15, which is difficult by hand, is relatively easy and smoothly performed by the guide of the moving roller 32. After finishing the initial winding operation, as shown in FIG. It is to be adjusted before and after winding to the desired diameter.

The pressure roller 33 is located inside the corrugated pipe 1 to press the corrugated pipe 15 passing through the upper surface of the fixed roller 31 and the moving roller 32 at a proper pressure to be in close contact with the material. The crimp tube 1 is molded to a predetermined diameter by maintaining the pressing force and the friction force.

The pressure roller 33 rotates at a constant speed by the rotational force of the motor 70, and is moved up and down by the elevating means 50 to adjust the pressing force, or release the bite at the first work and at the completion of the work. The motor 70 uses a sub-motor capable of finely adjusting its speed, or, in the case of a DC motor, so that the speed control using the slidance can be performed so that the processing conditions of the wrinkle-forming part 30 can be performed. It is desirable to have the molding at different speeds, for example.

The lifting means 50 is a manual adjustment method that is moved up and down by the spiral shaft 52 rotated by the control handle 51 in the drawing, but using an oil, pneumatic in an automatic manner not shown It is also possible to adjust the lifting state by installing a cylinder that makes the piston move forward and backward.

In addition, in the case of the manual adjustment method, by adjusting the stationary motor in place of the control handle 51 may be made to adjust the lifting height by the button.

In the process of processing the pleated molding part 30 having the above-described structure, first, as shown in FIG. 3, the pleated tube 15 having several wrinkles in a straight line is fixed to the roller 31 and the upper portion of the movable roller 32. After passing through the lower portion of the pressurizing roller 33, and then rounded to a predetermined diameter to ensure that the most one of the corrugation bend in line with the second corrugation bend of the corrugated pipe 15 is continuously moved horizontally and then fixed The roller is pressed between the roller 31 and the moving roller 32 and the pressure roller 33 to achieve a spiral.

Therefore, the first corrugated pipe (1) wound in the same process as winding a tape in a cylindrical tube will have a single layer, and then will be wound in a state of being stacked in two layers and then in three layers, The number of layers forming this multiple ply is determined by the number of wrinkles of the corrugated pipe 15 formed by the rolling process.

That is, as shown in FIG. 3, when the corrugation pipe 15 formed with four corrugations is wound in the spiral direction to have the same winding, the corrugated pipe 1 of four layers is formed from the fourth winding operation. Subsequently, a four-ply corrugated tube is formed and subsequently molded.

At this time, since the thickness of the corrugated pipe 15 passing between the fixed roller 31 and the moving roller 32 and the pressing roller 33 is constant, the thickness gradually increases, so that the fixed roller 31 and the moving roller The gap between the 32 and the pressure roller 33 is set to be gradually different so that it can be molded with a suitable pressing force in accordance with the thickness change.

5 shows the state in which the four-ply corrugated pipe 1 is formed by such a process, partially cut out.

4 shows a state in which a two-ply corrugated tube 1 is formed in another embodiment, which is achieved by supplying a corrugated tube 15 having two lines of corrugation formed therein to the corrugated portion 30.

The cut portion 40 is a structural portion that is to be spread so that the corrugated pipe (1) completed in the above process is produced to lead to a single pipe, cut to fit the purpose to a predetermined length.

8 and 9 show an installation state of the cut part 40, and is horizontally supported on the support roller 42 in the moving direction of the corrugated pipe 1 wound in the hollow cylinder by the corrugated part 30. FIG. This cutting is performed by providing a vertical cylinder 45 and a cutting torch 41 which can be moved up, down, left and right by a horizontal cylinder 46 on a substrate 44 mounted on a post 43. The torch 41 is moved by a controller not shown and cuts the corrugated pipe 1 at an appropriate position.

That is, when setting the length of the corrugated pipe 1 to be cut in the controller, the cutting torch 41 is lowered as shown in the eighth degree at the position, and is close to the groove part dug out of the corrugation of the corrugated pipe 1. Flame at a temperature suitable for cutting is formed at the nozzle of the cutting torch 41 and the cutting is started, and is wound in a spiral and is automatically rotated in the process of the pleated molding part 30 to be cut in a circular shape.

At this time, when the cutting torch 41 continues along the groove of the corrugated pipe 1, the cutting torch has a result of cutting as a whole. Thus, the cutting torch moved to the next pitch by performing the cutting operation of one rotation along the groove ( 41) to make a complete cut by performing a linear motion to the position where the first cut was made:

The end of the corrugated pipe 1 cut as described above may not have the effect of being cut in a vertical line, but since the use of the corrugated pipe 1 is used through a joint process by other pipes and welding, it is cut in one layer by one pitch. Will not interfere with the use.

Reference numeral 66 in the drawing shows a sorting box.

The present invention as described above, first, the number of the desired multiple ply and its diameter setting is free and practical and convenient. Second, because all processes are automatic, no operator is required and economical time can be shortened. Third, since the corrugated pipe is actively supplied in the optimal state for processing the molded part, the processing state is smooth and there is no fear of defects.

Fourth, since it is made automatically from the supply of the material to the cutting of the finished product, it is a very useful design, such as to be able to spread the product at a lower price because it is convenient and the number of work is reduced.
