The present invention relates to a roller used in a rolling process or the like.

In general, in order to produce a rolled material in a steel mill, a rolling process is performed, and the rolling process is performed by inserting slabs, blooms, billets, etc., produced in a continuous casting process, between two rotating rolls to form a thin and long shape. will be.

The rolling mill is a device for forming a plate, a bar, etc. through plastic deformation of the material while passing the material between the rollers rotating at room temperature or high temperature. A transfer guide is installed between the rolling mill and the rolling mill to transfer the rolled material to the roller side of the next process.

When the reinforcing bar is produced in the rolling mill, reinforcing bars are continuously produced, which are cut to a predetermined length and loaded and stored.

It is an object of the present invention to provide a prefabricated roller which can divide and manage a fuselage.

An assembly roller according to an embodiment of the present invention for realizing the above object is a drive flange shaft, which is formed to be connected to the drive shaft, the body is formed to extend in a cylindrical shape, detachably coupled to one end of the body, the drive shaft And a driven flange shaft detachably coupled to the other end of the body, the driven flange shaft being connected to the driven shaft.

Here, the body may further include a mounting portion, which is formed concave to receive the drive or the barrel flange shaft on at least one of the major surfaces of both ends.

Here, the body may further include an alignment portion formed in the center of at least one of the major surfaces of both ends, concave to receive the projection protruding from the center of the drive or the cylinder flange shaft.

Here, a plurality of bolt holes may be formed in the main surfaces of both ends of the body and the driving and driven flange shafts in a circumferential direction corresponding to each other.

According to the assembled roller according to the present invention configured as described above, it is possible to take necessary measures for the part by separating the roller into several parts in case of damage or the like at one part of the roller.

1 is a cross-sectional view showing the assembled roller 100 according to an embodiment of the present invention,
2 is an exploded cross-sectional view of the assembled roller 100 of FIG.
3 is a side view of the assembled roller 100 of FIG. 1.

Hereinafter, with reference to the accompanying drawings, the assembled roller according to a preferred embodiment of the present invention will be described in detail. In the present specification, the same or similar reference numerals are assigned to the same or similar configurations in different embodiments, and the description thereof is replaced with the first description.

1 is a cross-sectional view showing the assembled roller 100 according to an embodiment of the present invention.

Referring to this drawing, the assembled roller 100 may include a body 110, a driving flange shaft 120, and a driven flange shaft 130.

The body 110 may be formed as a cylindrical body extending with a generally circular cross section. The body 110 may be cast as a metal material.

The drive flange shaft 120 is detachably coupled to one end of the body 110. The drive flange shaft 120 may be connected to the drive shaft of the motor to be a part receiving power.

The driven flange shaft 130 is detachably coupled to the other end of the body 110. The driven flange shaft 130 may be arranged in a symmetrical form with the drive flange shaft 120 with respect to the central portion of the body 110. In addition, the centers of the drive flange shaft 120 and the driven flange shaft 130 may be disposed to match the center line (C) of the body (110).

2 is an exploded cross-sectional view of the assembled roller of FIG. 1.

Referring to this figure, the mounting surface 111 that is formed more concave than the periphery of the main surface of both ends of the body 110 may be formed. By the mounting portion 111, the edge portion of the main surface can form a relatively protruding sleeve (112).

In the mounting portion 111, an alignment portion 113 that is formed concave corresponding to the center of the body 110 may also be formed. The alignment unit 113 may be formed to have a smaller diameter than the mounting unit 111.

In the mounting portion 111, the bolt hole 114 may also be opened. The bolt holes 114 may be formed in plural numbers spaced apart from each other along the circumferential direction of the mounting portion 111 or the body 110.

The drive flange shaft 120 may include a flange 121 and a shaft 122.

The flange 121 may be formed to have an area corresponding to the area of the mounting portion 111, and may be formed to be seated on the mounting portion 111.

The shaft 122 is formed to protrude from the flange 121 and is connected to the drive shaft. The shaft 122 will be formed at a position corresponding to the center of the flange 121 and also corresponding to the center line C of the body 110.

The protrusion 123 may be formed on the opposite side of the surface from which the shaft 122 of the flange 121 protrudes. The center of the protrusion 123 will be formed to coincide with the center of the flange 121 and the shaft 122.

A bolt hole 124 may be formed along the circumferential direction of the main surface of the flange 121. The bolt holes 124 may be formed of a plurality of dogs spaced apart from each other.

The driven flange shaft 130 may include a flange 131 and a shaft 132.

The flange 131 may be formed to have an area corresponding to the area of the mounting portion 111, and may be formed to be seated on the mounting portion 111.

The shaft 132 is formed to protrude from the flange 131, and is connected to the drive shaft. The shaft 132 will be formed at a position corresponding to the center of the flange 131 and also corresponding to the center line C of the body 110.

The protrusion 133 may be formed on the opposite side of the surface from which the shaft 132 of the flange 131 protrudes. The center of the projection 133 will be formed to coincide with the center of the flange 131 and the shaft 132.

A bolt hole 134 may be formed along the circumferential direction of the main surface of the flange 131. The bolt holes 134 may be formed of a plurality of dogs spaced apart from each other.

According to this configuration, the flange 121 of the drive flange shaft 120 is inserted into the mounting portion 111 of the body 110 is seated. At this time, the protrusion 123 of the flange 121 is inserted into the alignment portion 113 of the body 110.

After the flange 121 and the protrusion 123 are seated in the mounting portion 111 and the alignment portion 113, respectively, the fastening pieces 140 are inserted into the bolt holes 114 and 124 to fasten them.

The manner in which the driven flange shaft 130 is fastened to the body 110 may be according to the manner in which the above driving flange shaft 120 is fastened to the body 110.

3 is a side view of the assembled roller of FIG. 1.

Referring to this drawing, the drive flange shaft 120 is wrapped by the sleeve 122 of the body 110.

The shaft 122 is positioned at the center of the flange 121 of the driving flange shaft 120. The fastening piece 140 for fastening the flange 121 to the body 110 may be arranged to draw a circle about the shaft 120 above.

Such a prefabricated roller is not limited to the configuration and manner of operation of the embodiments described above. The above embodiments may be configured such that various modifications may be made by selectively combining all or part of the embodiments.
