This embodiment is provided to more fully describe the present invention to those skilled in the art. Thus, the shape of the elements in the figures has been exaggerated to emphasize a clearer description.

In addition, although specific terms are used in the drawings and specification of the present invention, they are used for the purpose of describing the present invention only and are not used to limit the scope of the present invention described in the claims or the claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.

The rotary cutting apparatus having a lightweight spacing member according to the present invention is a device that cuts and rewinds the steel material provided in a wide-width coil state 7 to have various widths, and turns it into a coil state 9 again.

A rotary cutting apparatus having a lightweight spacing member according to the present invention includes a rotary shaft 3, a cutting member 5 for cutting the material by being pinched by the rotary shaft 3, a cutting member 5, And a spacing member 1 interposed between the steel strips 1 and 2 to adjust the cutting interval of the steel strips.

The rotary shaft 3 is located between the coil 7 having a wide width which is not cut and the coil 9 having a certain standard width and has a constant shape but preferably a cylindrical shape.

The cutting member 5 has a predetermined shape but preferably has a thin disc shape. The cutting member 5 is accommodated in the rotary shaft 3 and rotates together with the rotary shaft 3 to cut the steel material.

The cutting member 5 may be formed of a predetermined material, but it is preferable to use a special steel as a metal material.

The spacing member 1 includes a ring-shaped body portion 11 including a receiving hole 111 to be inserted into the outer diameter of the rotating shaft 3, and the body portion 11 11 has an outer surface 112 which is parallel to the rotating shaft 3 and has a predetermined width and forms a ring-shaped outer circumferential surface, an inner surface 113 forming an outer circumferential surface of the receiving hole 111, And a through hole 115 formed to penetrate the body part 11 so as to reduce the weight of the body part 11. [

The body portion 11 may be formed of a predetermined material, but it is preferable that the body portion 11 is made of metal.

The outer surface 112 may have a width ranging from 5 mm to 100 mm. The receiving hole 111 has an outer diameter of about 220 mm. The side surface 114 has a width of about 60 mm.

The through hole 115 is formed to penetrate the outer surface 112 and the inner surface 113 in the circumferential direction as shown in FIG. 3 (a). However, as shown in FIG. 3 (b) The through hole 115 may be formed to penetrate through the side surface 114 when the predetermined width of the through hole 115 is not sufficient to form the through hole 115. [

The through holes 115 may be formed to penetrate the outer surface 112 in two rows in the circumferential direction when the outer surface 112 has a predetermined width.

According to one embodiment of the present invention, as shown in FIG. 4, the spacing member 1 further includes a surface portion 13 formed to surround the outer surface 112 outside the outer surface 112 .

Since the surface portion 13 is formed to surround the outer surface 112 of the body portion 11, it is possible to prevent the surface of the steel material from being damaged even if the spacing member 1 rotates at a high speed, It is possible to prevent contaminants such as flour, which are generated during cutting, from flowing into the through holes 115 formed in the outer surface 112.

The surface portion 13 is made of a material having a hardness lower than that of an iron plate material cut with a predetermined elasticity, preferably urethane, and may be formed by injection molding urethane or the like into the outer groove 116 to be described later .

As shown in FIG. 5, the surface portion 13 may be received in an outer groove 116 formed in the outer surface 112.

The outer groove 116 includes a horizontal surface 116a embedded in the outer surface 112 at a predetermined depth and parallel to the outer surface 112 and an outer surface 112a connecting both ends of the horizontal surface 116a and the outer surface 112 And is defined as a connecting surface 116b.

6 and 7, the outer grooves 116 connect the both ends of the horizontal surface 116a and the horizontal surface 116a with both ends of the outer surface 112, And the surface portion 13 may be formed so as to surround the entirety of the outer surface 12.

8 and 9, the body part 11 includes an inner groove 117 which is formed in the inner surface 113 to be inserted into the body part 11, Weight can be further reduced.

When the spacing member 1 is changed to adjust the cutting area of the steel material, the spacing member 1 is significantly weighted by the through hole 115 and the inner groove 117 The risk of accidents due to fatigue of the worker can be lowered, and the occurrence of chronic occupational diseases such as back pain can be prevented.

Further, when the steel material is cut, the surface portion 13 is formed on the outer surface 112 of the interval member 1 rotating at a high speed by the rotating shaft 3, so that the surface of the steel material can be prevented from being damaged. In addition, the surface portion 13 can prevent the contaminants such as flour, which are generated when the steel material is cut, from flowing into the through holes 115 formed to reduce the weight of the spacing member 1.

The foregoing detailed description is illustrative of the present invention. In addition, the foregoing is intended to illustrate and explain the preferred embodiments of the present invention, and the present invention may be used in various other combinations, modifications and environments. That is, it is possible to make changes or modifications within the scope of the concept of the invention disclosed in this specification, within the scope of the disclosure, and / or within the skill and knowledge of the art. The embodiments described herein are intended to illustrate the best mode for implementing the technical idea of the present invention and various modifications required for specific applications and uses of the present invention are also possible. Accordingly, the detailed description of the invention is not intended to limit the invention to the disclosed embodiments. It is also to be understood that the appended claims are intended to cover further embodiments.
