Description

[0001] Slitting Machine [0002]

The present invention relates to a slitting apparatus for cutting a raw material continuously supplied in the same manner as a coil steel sheet in a longitudinal direction, and in particular, To a slitting device for preventing quality deterioration.

Generally, the slitting apparatuses are generally made of steel sheet coils, hot-rolled steel sheets, cold-rolled steel sheets, electro-galvanized steel sheets, composite electro-galvanized steel sheets, hot-dip galvanized steel sheets, aluminum steel sheets, stainless steel sheets, laminated steel sheets, Quot; device "

1, a conventional slitting apparatus includes a roller cutting unit 5 for cutting a steel sheet 1 supplied from a feeding apparatus along a longitudinal direction thereof, A plurality of ring-shaped upper and lower knives 6 are provided on the outer periphery of the upper and lower rollers 5a and 5b which are rotated in the direction of the arrow A, and the spacing between the knives 6 is maintained by spacers.

Therefore, when the steel sheet 1 continuously fed by the feeding device is passed between the upper and lower rollers 5a and 5b, the sharp edges of the upper and lower knives 6 of the steel sheet 1 are shifted from each other And is cut as it is cut by the scissors along the longitudinal direction while being misaligned. At this time, a circular ring 7 made of rubber having frictional force is provided on the outer periphery of the spacer provided between the knives 6 to smoothly transfer the material.

Accordingly, when a plurality of knives are installed on the upper and lower rollers, a gap between the knives is adjusted to obtain a narrow width plate having a desired dimension. The cut narrow plate is placed on a winding roll located in front of the roller cutting portion And is wound and circulated in the form of a roll plate.

On the other hand, when a raw material supplied from a feeding device is cut to a desired size by using a plurality of knives spaced apart from each other at a predetermined interval, it is only necessary to cause a squirming with a width smaller than a desired dimension at one side edge or both side edges of the raw material .

Because these scarlet parts are rarely usable, they are collected separately through separate routes. At this time, a guide is provided in front of the roller cutting portion so that the corner portion of the raw material is separated from other narrow plate members so that the corner portion of the raw material does not move in the winding roll direction.

However, in the conventional slitting apparatus described above, since the guide provided at the front of the slitting apparatus has a structure that does not simply rotate to guide only the corner portions of the raw material, fine metal powder is generated due to friction with the corner portions of the raw material Which adversely affects the working environment as well as adversely affecting the quality of the product cut to a desired dimension.

As a result of investigating the prior art relating to the slitting apparatus of the present invention, a number of patent documents have been searched and some of them will be described as follows.

Patent Document 1 discloses an image forming apparatus in which an edge-up portion remaining on both side edges of a film obtained by cutting wide-width film fabrics is provided on an upper feed roller and a lower feed roller which are pressed against a first take-up shaft and a second take- The cross-sectional structure of the roller is made to be the first rubber layer for buffering, and the second rubber layer for flat pressing by pressing the edge portion is covered with the double layer, thereby preventing the film from being wound up more stably Up structure of a slitting winder for a thin film which can improve the quality of a product.

Patent Document 2 discloses a method of recovering scrap, which is mounted on a slitting apparatus for continuously slitting and cutting a steel coil into a plurality of unit steel coils so as to continuously guide the movement of scrap, And a drum and a driving unit for winding the scrap moved. One of the plurality of guide rollers is coupled to an elevation guide hole formed vertically to the support plate, and supported by the elastic force of the spring, And a variable guide roller (GR), so that the coarse steel sheet coils generated at both sides of the steel coil can be easily wound without breaking.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a method of cutting a metal material, It is an object of the present invention to provide a slitting apparatus capable of preventing the deterioration of the quality of cut products by improving the working environment.

According to an aspect of the present invention, there is provided a cutting device for cutting a raw material supplied from a feeding device using a plurality of cutting knives installed at upper and lower rollers, A roller cutting portion for cutting along the longitudinal direction in the size; And an edge guide portion provided in front of the roller cutting portion so that the edge portion of the raw material cut by the cutting knife does not move in the winding roll direction,

The edge guide portion includes a positioning bar positioned in front of the roller cutting portion and having a hole formed at a predetermined interval, and an edge guide guiding the corner portion of the raw material without friction and being coupled to the hole of the positioning bar .

According to the slitting apparatus of the present invention, the edge guide portion includes a movable member to which the positioning bar is attached and is rotatably installed on one side of a support for supporting both ends of the upper roller and the lower roller, And a locking member provided on the movable member so as to prevent the movable member from rotating.

According to the slitting apparatus of the present invention, the edge guide includes a guide roller for guiding a corner portion of the raw material while rotating, and a support shaft inserted in a hole of the positioning bar and rotatably supporting the guide roller .

Further, according to the slitting apparatus of the present invention, the pair of edge guides are provided at regular intervals so as to guide the corner portions generated on both sides in the width direction of the raw material.

Further, according to the slitting apparatus of the present invention, the raw material is a metal plate wound in a coil shape.

The slitting apparatus of the present invention is characterized in that, in a process of guiding a corner portion generated during a cutting process of a raw material using a cutting knife of a roller cutting portion to a path different from a conveying path of a cutting product, So that no metal powder due to friction between the metals is generated, thereby improving the working environment and preventing the quality of the cut product from being deteriorated.

According to the slitting apparatus of the present invention, since the edge guide is coupled to the hole of the positioning bar and its position is determined, it is possible to stably guide the corner portion regardless of the position where the cornering occurs, and the positioning of the edge guide There is an effect that it becomes easy.

Further, according to the slitting apparatus of the present invention, since the positioning bar is attached to the movable member and rotated, and the movable member is fixed by the lock member, it is possible to prevent the interference of the positioning knife There is no effect.

Further, according to the slitting apparatus of the present invention, since a pair of edge guides are provided on the positioning bar at regular intervals, there is an effect that the corner portions generated on both sides of the raw material can be simultaneously guided.
