DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. , And this does not mean that the technical idea and scope of the present invention are limited.

A rolling mill 1 having a uniform load distribution according to a preferred embodiment of the present invention forms grooves having various shapes on a metal strip by pressing the upper and lower portions of the linearly transported metal strips, A rolling roller 100 having a coupling groove 130 formed at the center of both sides thereof so as to uniformly distribute a load for pressing the lower portion of the rolling roller 100 and a coupling formed at one side of the rolling roller 100 through the center of the rolling roller 100, A rotary shaft 200 fixedly coupled to the groove 130 to support and rotate the rolling roller 100 and a coupling groove 130 formed on the other side of the rolling roller 100 positioned on the rotary shaft 200, The sleeve 300 is rotated together with the rolling roller 100 and the sleeve 300 coupled to the coupling groove 110 of the rolling roller 100 is coupled to the end of the rotation shaft 200 to prevent the sleeve 300 (Not shown).

Hereinafter, the constituent members of the rolling mill 1 having a uniform load distribution according to a preferred embodiment of the present invention and the connection relationship thereof will be described with reference to FIGS. 2 to 3 as follows.

Here, the rolling roller 100 is made of a metal material having excellent durability such as iron, and presses the upper and lower surfaces of the metal strips linearly transported by a device such as a winch to form a constant thickness of the metal strip And forms a groove having various shapes such as a spiral or rhombic pattern on the upper surface of the metal strip.

In order to form grooves on the metal strip by pressing the metal strip, the protrusions 110 are formed on the outer circumferential surface of the rolling roller 100 in various shapes, It is preferable that the outer peripheral surface of the rolling roller 100 located at the lower portion is formed only on the rolling roller 100 and is formed flat without the protrusions 110. [

A through hole 120 is formed in the center of the rolling roller 100 so that the rotating shaft 200 to be described later can be inserted into the through hole 120. A through hole 120 is formed in the center of the through hole 120, 200 and the sleeve 300 are fixedly coupled to each other to be rotatable together.

The engagement groove 130 may be formed on the outer side of the through hole 120 so that the rotation shaft 200 and the sleeve 300 to be described later can be coupled to both sides of the rolling roller 100. [ And is formed radially outwardly of the insertion groove 131 so that the rotary shaft 200 inserted into the insertion groove 131 and the sleeve 300 can be fixed to the insertion groove 131 And a fixing groove 132.

That is, since the engaging groove 130 in which the insertion groove 131 and the fixing groove 132 are formed integrally is formed on both sides of the above-described rolling roller 100, the load of the rolling roller 100, which presses the metal strip, And not distributed to the center, but distributed evenly throughout the whole.

The rotating shaft 200 is inserted into the through hole 120 formed at the center of the rolling roller 100 and fixed to the coupling groove 130 formed on one side of the rolling roller 100, Like the above-described rolling roller 100, is made of a metal material having excellent durability such as iron, and connected to a device for generating a rotational force, such as a driving motor, though not shown, It is a role to play.

The rotary shaft 200 has a predetermined length and is connected to a device for generating a rotational force to transmit a rotational force to the rotary shaft 200. The rotary shaft 200 is extended from the connection part 210 to be described later And a first coupling member 210 which is fixedly coupled to the coupling groove 130 of the rolling roller 100 and is positioned between the coupling portion 210 and the supporting portion 220. The supporting portion 220 supports the sleeve 300, (230).

The end of the support part 220 is formed with a male screw thread so that the fixing nut 400 to be described later can be fastened. The first engagement part 230 is engaged with the engagement groove of the rolling roller 100 (130) so as to correspond to the coupling groove (130).

The roller 120 is positioned on the supporting portion 220 of the rotating shaft 200 protruding through the through hole 120 of the rolling roller 100 and fixedly coupled to the coupling groove 130 of the rolling roller 100 The sleeve 300 is provided with the sleeve 300 so as to smoothly rotate the rolling roller 100 fixedly coupled to the rotation shaft 200 and to rotate the rolling roller 100 on the support portion 220 of the rotation shaft 200, (100) to prevent it from flowing in the left and right directions.

The sleeve 300 may include an insertion portion 310 having an inner hollow formed therein so as to be inserted into the support portion 220 of the rotary shaft 200. The insertion portion 310 is integrally formed with the insertion portion 310, And a second engaging portion 320 fixedly coupled to the engaging groove 130 of the first engaging portion 100. The second engaging portion 320 corresponds to the engaging groove 130 so as to be engageable with the engaging groove 130 of the rolling roller 100 described above in the same manner as the first engaging portion 230 of the rotating shaft 200 It is preferable that they are formed in the same shape and size.

A fixing nut 400 is fastened to an end portion of the support portion 220 of the rotary shaft 200 protruding through the through hole 130 of the rolling roller 100. The fixing nut 400 is fixed to the rotary shaft 200 The sleeve 300 is fixed to the inner surface of the support shaft 220 so that the sleeve 300 can be engaged with the male thread formed at the end of the support 220 of the rotary shaft 200. [ A female thread is formed. The fixing nut 400 is the same as the fixing nut according to the related art, and will be omitted for the sake of simplification of the description.

Accordingly, since the rotary shaft 200 and the sleeve 300 are fixedly coupled to the defect grooves 130 formed on both sides of the rolling roller 100, the load of the rolling roller 100 is reduced to one side And the sleeve 300 can be prevented from being damaged and defective. In addition, the thickness and the groove of the metal strip to be pressed can be fixed The productivity is improved.
