Are installed so that both ends protrude from the housing 110 and the shaft bearing housing 38 fixedly installed in the housing 110 so that the first pulley 32 is at one end and the wheel holder 36 is at the other end. Heel holder 36 to be rotated by the drive motor 50 is connected to the shaft 34, the first pulley 32 and the belt 40 of the shaft 34 and the second pulley 52 of the rotating shaft. The first and second rollers 212 and 214 are formed at a lower portion of the cutting wheel 20 and the first and second guide rails 112 and 14 to be transported by the shaft 34. Guide hole 232 is formed so that the cutting wheel 20 is partially protruded to 230 to cut the cutting object 10 at the cutting position. It is configured to include a round trip frame 210 and the body 310, in which the housing 110, the support 320 of a predetermined height in the downward direction in the right and left sides of the upper surface of the installation provided.

The cutting wheel 20 is disc-shaped to the shaft 34 by a cutting wheel holder 36 formed at one end of the shaft 34 inserted into the shaft bearing housing 38 fixedly installed inside the housing 110. It is built up.

A first pulley 32 is formed at the other end of the shaft 34 through which the shaft bearing housing 38 is inserted and fixedly coupled to the cutting wheel 20 with the wheel holder 36. It is called a wheel fixing rod (30).

The drive motor 50 is provided with a second pulley 52 to be connected to the first pulley 32 and the belt 40.

The cutting wheel 20 mainly uses a grinding wheel and a diamond cutting wheel.

However, the grinding wheel is a diamond cutting wheel is mainly used to be easily broken when hit by the cutting object (10) during rotation or while rotating.

The shaft 34 transmits the rotational force to the cutting wheel 20 fixed to the wheel holder 36, the shaft bearing housing 38 to the housing 110, the shaft 34 coupled to the cutting wheel 20 It serves to fix.

The shaft bearing housing 38 is fixed to the inner wall of the housing 110, and the shaft 34, the wheel holder 36, and the cutting wheel 20 are rotated by the drive motor 50.

The first pulley 32 and the second pulley 52 are connected to the belt 40 so that the shaft 34 rotates by the rotation of the drive motor 50.

The cutting wheel 20 is rotated by the rotation of the shaft 34, and the cutting wheel 20 rotating at a high speed becomes the cutting position, and the cutting object 10 is transferred to the cutting position to cut the cutting work. .

Rotation ratios of the first pulley 32 and the second pulley 52 may be the same or different according to various conditions such as the material and thickness of the cutting object 10.

One or more number of the belt 40 may be provided, but in the present invention, two numbers of the belt 40 are installed.

The drive motor 50 has a rotation speed different according to the performance, but in the present invention, the drive motor 50 having a rotation speed of about 3600 rpm is used.

One side of the housing 110 of the body 310 described above is provided with a driving button 120 for simultaneously driving the driving motor 50 and the cutting oil motor 190 to be described later.

The drive button 120 of the present invention is pressed once to drive the drive motor 50 and press once more to stop the drive motor 50.

And, the lower portion of the support 32 of the body 310 is provided with a cutting oil circulation cylinder 150 for circulating to supply the cutting oil 140 to the cutting wheel 20.

The first and second guide rails 112 and 114 are formed at both edges of the upper end of the housing 110.

The first and second guide rails 112 and 114 are formed to guide the reciprocation of the reciprocating frame 210 of the transport means to be described later.

In this case, the cross section of the first guide rail 112 is triangular, and the second guide rail 114 is planar.

The reason why the cross section of the first guide rail 112 is triangular is to prevent the first and second rollers 212 and 214 of the reciprocating frame 210 from leaving the first and second guide rails 112 and 114 during transportation. to be.

That is, the groove 213 is formed so that the first roller 212 formed in the lower portion of the reciprocating frame 210 matches the shape of the first guide rail 112 so that the first roller 212 in the first guide rail 112 is formed. ) Is not allowed to escape.

In addition, the reason that the second guide rail 114 is in a planar shape is that the second guide rail 114 also has the first and second guide rails 112 and 14 as the cross section is formed in a triangular shape like the first guide rail 112. This is because it is troublesome to keep the parallelism of.

Thus, the second roller 214 of the reciprocating frame 210 rotates in rolling contact along the second guide rail 114.

In addition, a cutting oil reservoir 130 is formed in the housing 110 to collect the cutting oil 140 supplied to the cutting wheel 20, and to an outlet 132 formed in the cutting oil reservoir 130. The cutting oil 140 is discharged and collected in the cutting oil circulation barrel 150 through the cutting oil discharge hose 184.

In addition, a hook hole 160 through which the housing 110 is lifted is formed on the front surface of the housing 110, and a part of the driving motor 50 is exposed on the rear side of the housing 110.

In this case, the reason why the driving motor 50 is exposed is to cool the air generated by the air as soon as it is driven and generated.

In order to protect the belt 40 connecting the first and second pulleys 32 and 52, a protector 170 is installed at a side of the housing 110.

The reciprocating frame 210 is used to fix the cut object 10 and transfer it to the cutting position.

First and second rollers 212 and 214 are formed at the lower portion of the reciprocating frame 210 so as to be transported by the first and second guide rails 112 and 114 of the housing 110 and the cutting wheel 20 at the bottom plate 230. The guide hole 232 is formed so as to protrude a part to cut the cutting object 10 at the cutting position.

In addition, first and second cover plates 216 and 218 which are connected to the first and second hinges 217 and 219 to open and close are formed at the upper end of the reciprocating frame 210, and partially protrude from the inside of the reciprocating frame 210. The fixing part which fixes the cut object 10 is formed.

One or more first hinges 217 are provided at rear ends of the reciprocating frame 210 and the first cover plate 216.

In this case, the reason why the first hinge 217 is formed is that the first cover plate 216 and the first cover plate 216 connected to the first cover plate 216 in the reciprocating frame 210 to check the wear degree of the cutting wheel 20 and the like. This is to allow the two cover plates 218 to be opened together.

In addition, at least one second hinge 219 is installed at a central portion of the second cover plate 218 to be parallel to the first hinge 217.

In this case, the reason why the second hinge 219 is installed is to open the second cover plate 218, which is about half of the first and second cover plates 216 and 218, and to fix the cut object 10 to be described below. ) And the interlocking vise 222.

In addition, another reason why the first and second cover plates 216 and 218 are installed is to prevent scattering of chips generated when the cutting wheel 20 cuts the cutting object 10.

Of course, only one first cover plate 216 may be installed, and the first and second cover plates 216 and 218 may be formed of a transparent plate.

The lower surface of the second cover plate 218 is fixedly attached to the cutting oil supply hose 180 to supply the cutting oil 140 to the cutting wheel (20).

The first and second rollers 212 and 214 described above are formed at both edges of the reciprocating frame 210.

The first roller 212 is made of one or more grooves 213 is formed in the center of the circumferential surface is inserted into the triangle of the first guide rail 112 of the housing 110 to rotate, one or more formed The second roller 214 rotates in rolling contact with the second guide rail 114 of the housing 110 that is planar.

In addition, the bottom plate 230 of the reciprocating frame 210 is formed with a guide hole 232 penetrating a predetermined width and a predetermined length.

The guide hole 232 is a cutting oil which is ejected through the cutting oil supply hose 180 to a portion where the cutting wheel 20 which rotates at high speed is partially protruded into the reciprocating frame 210 to cut the cutting object 10. It is also where the 140 is discharged to the cutting oil reservoir 130.

In addition, a bracket 240 is formed at an edge lower end of either the side of the first roller 212 or the second roller 214 or both sides of the front surface of the reciprocating frame 210, the locking pin on the bracket 240 242 is formed.

The bracket 240 prevents the reciprocating frame 210 from being reversed more than a predetermined time, and the locking pin 242 prevents the reciprocating frame 210 from moving forward or more when the upper end of the housing 110 is caught.

That is, the reason why the bracket 240 and the locking pin 242 is formed is to prevent the cutting wheel 20 from being damaged by being caught by the reciprocating frame 210 that is slidably moved during the cutting operation.

When the locking pin 242 is lifted upward, the locking of the reciprocating frame 210 is released to move the reciprocating frame 210 to the front of the operator.

Therefore, when the reciprocating frame 210 is reversed, the locking pin 242 is reversed along the upper end of the housing 110, and the lower recess of the locking pin 242 is caught on the upper end of the housing 110, so that the reciprocating frame 210 is Is locked.

The fixing part is fixed to the bottom plate 230 of the reciprocating frame 210, the fixed vise 220, and the forward / backward corresponding to the side of the fixed vise 220, tightening the cutting object 10 therebetween The interlocking vise 222 is fixed to the vertical plate 230a integrally formed at the front end of the bottom plate 230, and the handle is constructed to protrude outward to move forward / backward in the rotational direction to move the interlocking vise 222. It is formed by the moving handle 223 to move backward.

The fixing vise 220 is fixed to the upper surface of the base plate 230 at a right angle to the guide hole (232).

In addition, the cutting object 10 to be cut is placed in front of the fixed vise 220.

In this case, in order to cut the cutting object 10 at a predetermined interval, an extension bar 224 is formed at one side of the fixed vise 220 and a ruler 225 is installed thereon.

The extension bar 224 may be drawn on the scale itself to serve as a ruler 225.

Therefore, the scale indicating piece 226 is formed in the extension bar 224.

The end portion of the scale indicating piece 226 indicates the scale of the ruler 225, and can be linearly moved on the ruler 225 and fixed at an arbitrary position.

The interlocking vice 222 is installed to linearly reciprocate along the guide hole 232 formed in the bottom plate 230 of the reciprocating frame 210.

In addition, a cutting groove 234 is formed at the lower portion of the fixed vise 220 and the interlocking vise 222 to coincide with the guide hole 232.

The cutting groove 234 is formed so that the cutting wheel 20 does not interfere with the cutting of the cutting object 10.

The movement handle 223 extends from the interlocking vise 222 to protrude toward the front of the reciprocating frame 210.

When the moving handle 223 is turned clockwise, the interlocking vise 222 is moved in the direction of the fixed vise 220, and when turned counterclockwise, it moves in the opposite direction of the fixed vise 220.

In addition, the end of the movement handle 223 is perforated, and it is easy to insert a rotation rod (not shown) therein to hold the rotation rod and rotate the movement handle 223.

There are four supports 320 at the lower portion of the body 310, the height adjustment port 330 is attached to the lower portion of each support 320.

When the body 310 is inclined, the height adjusting device 330 is adjusted so that the body 310 is not inclined.

When the body 310 is tilted, the cutting wheel 20 may also be bent, such that the cutting wheel 20 may be damaged during the cutting operation.

A cutting oil motor 190 is installed at an upper end of the cutting oil circulation barrel 150 below the body 310. It is dipped to supply the cutting oil 140 to the cutting wheel 20.

The cutting oil motor 190 is connected to the cutting oil supply hose 180 to supply the cutting oil 140 pumped up to the suction pipe 192 to the cutting wheel 20.

Cutting oil 140 is installed to be supplied to the cutting wheel 20 to operate the drive button 120.

A cutting oil control valve 182 is installed at a part of the cutting oil supply hose 180 to adjust the amount of the cutting oil 140.

The cutting oil 140 supplied in this way passes through the cutting oil discharge hose 184 through the discharge port 132 and is discharged into the cutting oil circulation barrel 150 to be collected.

The lower portion of the cutting oil circulation barrel 150 is formed with a wheel 152 for movement.

The reason why the wheel 152 is formed is that there is a risk of deterioration when the cutting oil 140 is old. Therefore, the wheel 152 needs to be replaced after the predetermined period of time.

An outlet (not shown) is installed at one side wall between the support members 320 to supply power to the driving motor 50 and the cutting oil motor 190, and a power plug of the driving motor 50 and the cutting oil motor 190 is provided. Plug (not shown) into this outlet and connect external power to the outlet.

Referring to the operation of the present invention configured in this way in detail as follows.

With the cutting wheel 20 fixed to the shaft 34, plug all plugs (not shown) into the power source.

The movement handle 223 is turned counterclockwise to widen the gap between the fixed vise 220 and the interlocking vise 222.

The cutting object 10 is brought into contact with the fixed vise 220, and the moving handle 223 is turned clockwise so that the interlocking vise 222 firmly fixes the cutting object 10.

At this time, the position to be cut of the cutting object 10 is to be placed in the cutting groove 234.

If the cut object 10 is to be cut at a predetermined interval, the scale indicator 226 is moved at a predetermined interval, and the cut object 10 is also cut at a predetermined interval.

When the driving button 120 of the housing 110 is pressed, the driving motor 50 rotates, the cutting wheel 20 rotates together, and the cutting oil motor 190 also operates so that the cutting oil 140 is supplied to the cutting wheel 20. do.

Lifting the locking pin 242 on the upper end of the housing 110 to the state that the reciprocating frame 210 can move and then slowly push the reciprocating frame 210 in the direction of the cutting wheel 20 to rotate at high speed by hand to avoid The cut object 10 is cut by the cutting wheel 20.

When the reciprocating frame 210 is pushed at a high speed, the cutting wheel 20 may be broken while suddenly touching the cutting wheel 20 that rotates at a high speed.

The chips generated while cutting are collected in the housing 110 without being scattered to the outside by the first and second covers.

When the cutting object 10 is cut, the reciprocating frame 210 is moved to its original position, and the driving button 120 is pressed to stop the driving motor 50 and the cutting oil motor 190.
