Roll forming is one of the plastic working methods in which a plurality of forming rollers are sequentially arranged, and the plate material is sequentially formed through a series of forming flows through each of the forming rollers to form a desired cross-sectional shape on the flat plate. Such roll forming is generally used in a large number of cold roll forming processes, and is characterized in that it is suitable for mass production of long-length products having the same cross-sectional shape, and can also form complicated shapes that are difficult to be processed by bending and pressing . Patent Documents 1 to 4 disclose techniques relating to various roll forming devices, methods of using the roll forming devices, and the like.

Patent Document 1 relates to a rotary multi-stage roller apparatus of a roll forming machine, in which a plurality of roller sets are used to form a sheet material into a predetermined shape, wherein each of the plurality of roller sets includes a plurality of rollers, The sheet material is formed by passing the sheet material through the plurality of rollers included in the roller set. It also includes one or more rotatable stands and one or more stationary stands. The rotatable stand includes two or more roller sets, and the stationary stand includes a fixed roller set. The rotary stand includes two or more rotary parts on which the rollers set at the same position among the rollers included in the rotary stand are mounted, and the roller set set on the rotary stand by rotating the two or more rotary parts Is replaced. This configuration has the advantage of increasing the productivity by reducing roller replacement time.

Patent Document 2 has an effect of reducing unmanned and working personnel by automating a loading device for loading a finished product by operating a post-process immediately before cutting the end of a roll forming process.

Patent Document 3 is directed to a method for manufacturing a pleated smooth pipe using a roll forming apparatus and more particularly to a method for manufacturing a pleated smooth pipe using a roll forming apparatus, And a method for manufacturing a pleated smooth tube using a roll forming apparatus capable of improving flowability.

Patent Document 4 discloses a roll-forming machine comprising a row of forming stations including a stand and frames for a carrier of a pair of rollers displaceably mounted on the stand, , Wherein the sheet metal strip is driven through a series of forming stations that hold the sheet metal strip therebetween with roller pairs directed toward each other and form a sheet metal strip above the roller edges, To a roll-forming method.

However, the rollers used in such conventional roll forming apparatus have the following problems.

(1) As shown in Fig. 1, the roller is formed in a generally cylindrical shape, and a pattern of a predetermined shape is formed on the outer surface thereof in a form necessary for molding.

(2) If the pattern formed on the surface of the roller is too complicated to obtain the shape of the product to be roll-formed, it is impossible to form a pattern on one roller. Roll forming is performed in a desired shape through a plurality of formed rollers. Therefore, not only is the number of rollers increased, but also a lot of time and cost is required to manufacture a single roller.

(3) On the other hand, a roller having a pattern formed on its surface may be partially damaged when forming. As such, if any part of the pattern or any of the patterns is broken or crushed, it is not possible to roll-form the desired shape, so the entire roller must be replaced with a new one.

(4) Since one of the rollers must be replaced due to breakage of the pattern portion, which is considered to be finer than the defect or breakage of the roller itself, the maintenance cost of the roll forming apparatus is increased and the roll forming operation And the productivity drops.

(5) Since a pattern to be formed is to be formed on the surface of a cylindrical shape, it is difficult to perform the pattern forming operation on a limited surface, and in the case of complicated patterns, it is difficult to form the pattern on the roller.

Thus, various equivalents And variations may be present.

(Configuration)

2 to 4, the assembly type roller for roll forming according to the present invention includes a shaft 100 having a predetermined length, a pattern 210 formed on the outer circumferential surface of the shaft 100, And at least one circular disc 300 which is inserted into the shaft 100 and is key-locked so as to be positioned between the at least one pattern disc 200 and the pattern disc 200.

In particular, since the present invention can form a desired pattern by assembling at least one pattern disc 200 and at least one circular disc 300, a complicated shape can be easily processed, and even if breakage or the like occurs, So that they can be used alternately.

Also, according to the present invention, various complex patterns can be easily assembled and used according to the number of inserts of the pattern disc 200 and the circular disc 300 and the insertion order.

Hereinafter, each configuration will be described in more detail as follows.

As shown in Fig. 2, the shaft 100 is manufactured to have a predetermined length for manufacturing the assembled roller according to the present invention.

Particularly, as shown in FIG. 2, the shaft 100 has a key groove 110 formed on its outer surface over its entire length. The key groove 110 is used to fix a pattern disc 200 and a circular disc 300, which will be described later, with a key 111 manufactured by a conventional technique inserted therebetween.

As shown in FIG. 2, the pattern plate 200 is formed in a disk shape, and a pattern 210 is formed in a predetermined shape on a whole rim. In the drawing, the pattern 210 shows an example in which a waveform is formed so as to be capable of being formed.

As shown in FIG. 2, the pattern disc 200 has a mounting hole 220 formed at its center so as to be inserted into the shaft 100. The key groove 221 is further formed in the mounting hole 220 so as to protrude above the shaft 100 and the key 111 provided in the key groove 110 is fitted so that even if the shaft 100 rotates, Thereby preventing the disc 200 from rotating.

2, the circular disc 300 has the same shape as the pattern disc 200, but does not have the pattern 210 formed thereon. That is, the circular disk forms a mounting hole 310 so as to be inserted into the shaft 100 at the center. The key hole 311 is further formed in the mounting hole 310 so that the key 111 is inserted into the key groove 110 so as to protrude above the shaft 100. Even if the shaft 100 rotates, Thereby preventing the disc 300 from rotating.

The present invention as described above can be configured as shown in FIG. 3 by repeatedly fitting the pattern disc 200 and the circular disc 300 one by one to the shaft 100, as shown in FIG. That is, in the assembled roller according to the present invention, the pattern disc 200 is assembled in the odd-numbered order and the circular disc 300 is placed in the even-numbered order in the order of fitting to the shaft 100, have.

In the preferred embodiment of the present invention, although not shown in the drawing, the fixture is further provided at both ends of the shaft 100, so that the pattern disc 200 and the circular disc 300 sandwiched between the shaft 100 and the circular disc 300 are not detached It is desirable to be able to maintain a state as it is.

In the preferred embodiment of the present invention, the pattern disc 200 and the circular disc 300 may be made of any material that is used to manufacture rollers used in roll forming, The circular disc 200 is made of duralumin, and the circular disc 300 is made of a steel material. This is to increase the life of the prefabricated roller by reducing the abrasion and breakage rate of the pattern original plate 200 by fabricating the pattern original plate 200 which substantially forms the pattern with duralumin having excellent durability.

Meanwhile, according to the present invention, it is possible to obtain a prefabricated roller capable of performing roll forming in various forms according to the size and arrangement order of the pattern disc 200 and the circular disc 300.

(1) The diameter of the pattern disc 200 and the circular disc 300

The pattern disc 200 has a maximum diameter D larger than a diameter d of the circular disc 300, as shown in FIG. This is because the circular disc 300 having a small diameter is brought into contact with the steel sheet and the pattern steel sheet 200 having a large diameter is pressed against the steel sheet to obtain a waveform pattern It is for this reason.

(2) The thickness of the pattern disc 200 and the circular disc 300

The pattern disc 200 and the circular disc 300 may have the same or different thicknesses T and t as shown in FIG. That is, when the thickness T of the pattern disc 200 is increased, the thickness of the pattern is increased in proportion thereto. If the thickness t of the circular disc 300 is reduced, the effect of narrowing the distance between the pattern and the pattern You can expect.

Accordingly, it is preferable that the thickness T of the pattern disc 200 is equal to or greater than the thickness t of the circular disc 300. This is because the pattern forms the structural rigidity of the steel sheet to be roll-formed, so that the pattern forming portion is widened and the interval between the patterns is narrowed, thereby enhancing the structural rigidity of the roll-formed molded article.

Of course, the thickness T of the pattern disc 200 may be made thinner than the thickness t of the circular disc 300 when structural rigidity is not required to a great extent or if a pattern of a pattern is formed.

In the preferred embodiment of the present invention, the pattern disc 200 has a thickness T of 8 to 12 mm and the circular disc 300 has a thickness t of 3 to 5 mm desirable. This is because it is easy to form a pattern at the edge of the pattern original plate 200, and in particular, the pattern original plate 200, which is so thin, can form a large pattern by stacking several patterns. Likewise, the circular disk 300 can be easily adjusted in its thickness by using a plurality of thin sheets corresponding to the intervals between the patterns.

(3) Insertion order of pattern disc and circular disc

Fig. 3 shows an example in which an odd-numbered pattern plate is sandwiched by a shaft, and an even-numbered pattern plate is sandwiched by a circular disk. However, the assembled roller according to the present invention can be assembled in various patterns through various insertion sequences.

First, the number of discs is sandwiched by two. In other words, by assembling two pattern discs at the odd-numbered stage and sandwiching the two circular discs at the even-numbered stage, the size of the pattern doubles and the interval between the patterns doubles as compared with the assembled roller of FIG.

In addition, the number of circular discs between the pattern discs is different. That is, by arranging three pattern discs at the odd-numbered positions and sandwiching the two circular discs at the even-numbered positions, the gap between the pattern and the pattern can be formed differently at different ratios. The same effect can be expected when the number of pattern discs located between circular discs is different.

Particularly, in the case of varying the number of patterns, the pattern disc inserted at the odd-numbered position can be inserted differently. That is, three different patterns can be formed by inserting three discs of the first pattern disc and five discs of the second pattern disc. This is also the case for circular discs forming an interval.

As described above, according to the present invention, the pattern original plate for pattern formation and the circular original plate for maintaining the gap can be assembled by being inserted into a shaft in a predetermined size and order so that an operator can easily and quickly assemble In particular, the maintenance cost can be reduced because only a partially damaged disk can be used.

In addition, according to the arrangement of the pattern disc and the circular disc, various complicated patterns can be easily assembled to form a roll, thereby improving work efficiency and productivity.
