Description
The present invention relates to a roll-forming assembled roller, and more particularly, to a roll-forming assembled roller, in which at least one circular disk for maintaining a gap between a pattern plate for forming a pattern on a surface of a steel sheet and a pattern is sandwiched between shafts By forming rolls to be rollable, it is possible to arrange a pattern disc and a circular disc in accordance with a desired pattern to assemble the rollers and use the rolls for roll forming.
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.
SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and it is an object of the present invention to provide an apparatus and a method for assembling and using a roller having a desired pattern by sandwiching at least one circular disc and at least one pattern disc on a shaft, The present invention has been made in view of the above problems, and it is an object of the present invention to provide an assembled roller for roll forming, which can reduce the manufacturing cost and increase the productivity due to the replacement operation.
Particularly, the present invention can form a pattern of various complex shapes according to the number of pattern discs and circular discs sandwiched between the shafts and the order of fitting, and therefore, it is possible to easily form desired complex shapes by reassembling roll- Another object of the present invention is to provide a prefabricated roller for roll forming,
In addition, the present invention can reduce the wear rate of the pattern original plate which substantially forms the pattern by manufacturing the pattern original plate with duralumin excellent in abrasion resistance and making the circular original plate of steel, thereby prolonging the life of the forming roller, There is another purpose in providing the rollers.

(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.
