Description

Plate cutting apparatus

The present invention relates to a plate cutting machine, and more particularly, it is possible to maintain a comfortable working environment by preventing dust generated in the process of cutting the plate from leaking to the outside, and a rotating blade for cutting the plate is external. It relates to a plate cutting machine that can prevent safety accidents by not being exposed to.

In general, in the conventional cutting of plate materials such as aluminum, the worker cuts while moving the rotary saw blade while the plate is fixed, but this decreases workability and cuts the plate consistently and precisely because the operator works while moving the rotary saw blade directly. It was difficult to do.

In order to solve this problem, there has been disclosed a method of cutting a plate material by a rotating saw blade part that reciprocates from one side of the bed to the other side while the plate material is fixed to the top of the bed.

Such a plate cutting device can increase the efficiency of constantly cutting the plate, but it was very inconvenient to supply a heavy plate to the cutting position of the rotary saw blade from the top of the bed to the front and rear, left and right, rotational movement control, and pushing the rotary saw blade.

In addition, the plate cutting device has a problem of high risk of a safety accident due to carelessness of an operator because the rotating saw blade of the rotating saw blade is always protruding from the top of the bed and reciprocates.

In addition, since the plate material to be cut is supported only by the bed-shaped transverse support, the cutting operation may cause flow errors, thereby reducing processing precision.

So, in order to solve this problem, a technique described in Korean Patent Registration No. 10-0709310 as shown in FIGS. 1 to 3 has been proposed, the technical feature of which is a transverse support 2b for supporting a plate to be cut. In the bed (2) having a rotating saw blade (5) protruding from the lower side of the upper side to reciprocate along the rail (7) to cut a plate material such as aluminum, in the one side of the bed (2), the plate material back and forth A first support 12 in which a plurality of moving rollers 11 moving in the direction are arranged upward, and a second support 22 in which a plurality of moving rollers 21 moving in the left and right direction are arranged upward. Wow, the rotating plate 32 installed on the upper part of the bearing 31 for moving the plate material in the rotational direction, and a plurality of driving rollers 81a, 81b, 81c driven by a drive motor to move and supply the plate material to the rotating saw blade part 5 side. ) Is raised to protrude from the bottom of the bed (2) to the top by the first, second, third, and fourth lifting and lowering cylinders (15) (25) (35) (85), respectively. It is provided to operate downward, and a movable screw 102 is rotatably installed in parallel with the horizontal support 2b on the upper part of the bed 2, and an auxiliary support 106 that is cross-guided along the horizontal support 2b is installed. It is provided to support both sides of the plate and pressurize the upper surface of the plate by installing a pressurizing fixture 120 that moves up and down by the operating cylinder 125 in the center of the base 110 installed above the bed 2 And, the rotating saw blade (5) and the rail (7) is installed the support 40, the fifth lifting cylinder 45 is installed at the bottom, and the rotating saw blade (5) at both ends of the lower bed (2) Each of the limit switches (L1) (L2) for touch operation is installed, but the limit switch (L1) is a rotating saw blade unit that cuts and transfers the rotating saw blade unit 5 to return to its original position, and the limit switch (L2) is a rotating saw blade unit that returns to the original position. (5) It is characterized in that it is made to operate the stop control.

However, the technology described in Korean Patent Registration No. 10-0709310 can minimize safety accidents by allowing the rotating saw blade to be exposed to the outside only when cutting the plate material, and the advantage of minimizing flow errors by effectively clamping the plate material. However, since the rotary saw blade is completely exposed to the outside, safety accidents may still occur, and when cutting the plate, a large amount of dust is generated, and such dust cannot be removed.

On the other hand, there are further provided contact members 336 made of rubber or synthetic rubber on both sides of the auxiliary guide hole 332 formed under the clamp 330, the contact member 336 when fixing the plate, It is fixed in close contact and prevents the dust generated when cutting the plate from leaking to the outside, so that the dust can be stably collected through the auxiliary guide hole 332.

In addition, as another embodiment of the present invention, as shown in Figs. 7 to 10, cover portions 350 are provided to be elevating and descending on both sides of the clamp 330, so that the upper surface of the bed 200 and the plate are It is in close contact with the upper surface to prevent leakage of dust generated when cutting the plate.

Here, the cover part 350 includes an installation plate 360 installed on both sides of the clamp 330 and a guide groove 362 formed at a predetermined interval along the length direction of the installation plate 360 and the installation plate. It consists of a plurality of cover members 370 provided on the outside of 360 and provided to be elevating and descending along the guide groove 362.

In addition, the cover member 370 includes a cover plate 372 provided on the outside of the installation plate 360 and a guide protrusion formed on the inner side of the cover plate 372 so as to correspond to the guide groove 362 It consists of 374 and a support protrusion 376 protruding from both sides at the end of the guide protrusion 374.

At this time, support grooves 364 into which the support protrusions 376 are inserted are formed on both sides of the inner end of the guide groove 362.

So, the guide protrusion 374 and the support protrusion 376 of the cover member 370 forming the cover part 350 are inserted into the guide groove 362 and the support groove 364 and are lowered by their own weight. To move to the upper end of the guide protrusion 374 without being separated by the separation preventing member 378 provided at the upper end of the guide protrusion 374 and maintaining a downward movement, wherein the clamp 330 is located on the upper surface of the bed 200 When fixing the upper surface of the plate material, as shown in FIG. 10, the cover member 370 stably covers not only the upper surface of the plate material, but also the upper surface of the bed 200 positioned stepped with the plate material.

That is, when the clamp 330 moves downward while the cover member 370 is moved downward by its own weight, the lower end of the cover member 370 is the upper surface of the plate material located above the bed 200 The cover member 370 located at the side of the plate material moves downward and moves until the lower end contacts the upper surface of the bed 200, so that there is no difference between the plate material and the bed 200. It covers all the steps up to the chin.

Accordingly, dust generated when cutting the plate material is stably prevented from leaking to the outside by the cover member 370, so that the working environment can be comfortably maintained.

Of course, dust generated in the process of cutting the plate may be sucked and removed by a cyclone provided outside as described above, and when the cyclone is not used, dust collected by the cover unit 350 after work is separately It will be removed using the cleaning equipment.
