Description

Sheet material cutting apparatus {HEAVY BOARD CUTTING DEVICE}

The present invention relates to a device for cutting a high weight or low weight plate by firmly setting and fixing a reciprocating moving saw blade part. More specifically, the present invention relates to a device for moving a plate material on an upper end of a bed, freely moving, To a cutting tool which can simultaneously perform cutting and post-processing by a rotary saw blade.

In general, cutting of a heavy or low-weight plate material such as aluminum cuts a workpiece while moving the rotary saw blade while the plate material is fixed. However, since such an operation is performed by an operator while moving the rotary saw blade, workability is lowered, There is a problem in that it is difficult to perform cutting with a certain precision.

To solve this problem, a method has been disclosed in which a heavy saw blade is cut by a rotary saw blade portion which reciprocally moves from one side of the bed to the other side while fixing the heavyweight plate material on the upper portion of the bed.

Such an operation can increase the efficiency of cutting the heavy-weight plate constantly, but it has been very inconvenient to adjust the movement of the plate having a high weight from the top of the bed to the cutting position by the rotating saw blade.

That is, since it is difficult to manually perform the operation of adjusting the cutting position while moving the plate material in the front, rear, right, or left direction on the upper part of the bed, there is a problem that the workability is very inconvenient because it is performed using a separate forklift or the like.

In addition, when the aluminum plate is moved by a forklift or the like as described above, there is a problem that serious residual adsorption occurs on the aluminum plate due to the moving operation.

In addition, since the rotary saw blade of the rotary saw blade portion reciprocates in a state where the rotary saw blade protrudes to the upper portion of the bed, there is a high risk of a safety accident due to carelessness of the operator.

In order to solve such a problem, there has been provided a high-weight plate cutting apparatus of Utility Model Registration Nos. 20-0402634 and 20-0414113 previously filed and registered by the present applicant.

The above-described sheet material cutting device is configured to rotate and transfer the sheet material placed on the upper end of the bed by the rising and falling rollers, which makes it impossible to rapidly rotate and transfer the sheet material.

Further, there is a problem that it is very difficult to cut different sheet materials at one time, and it is only possible to cut by a cutting saw blade, and it is troublesome to use a separate apparatus for the post-processing of the cutting surface.

Further, since there is no apparatus for setting the cutting position of the plate material, it is troublesome to adjust the cutting position of the plate material by artificially.

In addition, the conventional sheet material cutting apparatus has a problem that the discharge of sludge generated during processing is not easy.

On the other hand, the sludge recovered in the recovery tank 410 is compressed and discharged by a separate press.

A process of cutting the plate material by the plate material cutting device configured as above will be described.

First, when the workpiece is pushed into the bed 110 of the machining unit 100 with the workpiece being pushed into the bed 110 in a state where the workpiece to be cut is placed on the workpiece loading unit 200, the workpiece is loaded on the roller 203 of the workpiece loading unit Bed. At this time, it is preferable that air is jetted from the air nozzle 111 provided on the bed.

When the plate material is injected in the state in which the air is sprayed as described above, the plate material is levitated on the bed 110 finely by the air. The worker can easily push the plumbed material into the material supply unit 300 installed in the rear side.

When the plate material is fed into the material supply unit 300, the drive motor M1 is operated to advance the plate feeder 330 to the position where the plate material is inserted. In the advanced state, the cylinder 344 of the pressurizer 340 is actuated to push and rotate the rotating piece 342 so that the pressing block 345 presses the plate material.

In this state, the drive motor M1 rotates in the reverse direction to feed the sheet material transfer unit 330 rearward, and the sheet material pressed by the presser is transferred backward.

On the other hand, even when the nozzle 322 provided on the bed 320 of the material supply unit 300 blows air, the plate material is easily pushed backward.

In this state, the control unit 500 inputs the width and the length quantity to be cut, and then operates.

When the input is completed, the driving motor M1 is driven to advance the plate conveying unit 330 to push the plate material into the processing unit 110. At this time, if the width of the plate is short or long, the following operation is performed to perform the setting.

That is, after the plate material is sent to the machining portion 110 by the plate feeder 330 as described above, the cylinder 353 is operated to rotate the rotator 352 so that the plunger 355 is positioned on the side of the plate material Thereafter, the motor 356 operates to cause the plunger to move to the side by pushing the side of the plate material.

After the completion of the transfer, the plate adherer 140 provided at the fixing part 130 is positioned at the side of the inserted plate, and then the actuating button of the cylinder 144 provided at the control part is pressed to operate the cylinder 144, ) Further presses the side portion of the plate member to come into close contact with the one side portion.

The cylinder S1 of the fixing portion 130 is operated to lower the clamp 132 and the pressing member 134 presses the plate 132 to the plate member 140. [ As shown in Fig.

Then, the cylinder S4 of the processing means 120 is operated to move the support table 121 up and down. The drive motor M4 is operated and the pinion 128 provided on the axis of the drive motor moves the cutting saw blade 125 and the polishing saw blade 126 along the rak 127 Thereby allowing the transfer to the side.

As the cutting saw blade 125 and the polishing saw blade 126 are conveyed, the fixed plate material is cut, and at the same time, the surface of the polishing saw blade 126 is polished to the cut-off portion.

At this time, the sludge caused by the cutting and polishing is transferred to the sludge recovery unit 400 by the sludge transfer unit 129, transferred by the transfer belt of the sludge recovery unit, and recovered to the collection bottle 410.

Thus, when the cutting and polishing process is completed, the cylinder S4 of the processing means is operated in reverse to lower the support table 121, and the motor S4 is rotated in the reverse direction to return the processing means to the original position.

As described above, the plate material cutting apparatus of the present invention has a merit that not only a low weight but also a high-weight plate material can be fed and conveyed and can be freely moved and set, and the plate material having been set is firmly fixed, In addition, by machining the cut surface, it is not necessary to further cut the cut surface, thereby improving the work efficiency.
