The present invention relates to a cutting device of a lounge used for collecting flat plates by thinly cutting the hull (land) from the ingot (generally known as digestion) when the hull is worn out.

When the hull is worn and the ship is dismantled, it is dismantled and sold scrap of metal materials (bar, plate, section steel) as recycled goods.

For this reason, as a method of dismantling the hull, the horizontal protrusions of the hull floating on the sea are gas-cut (generally referred to as large resolution), and the mass is suspended using a marine crane or a crane extending from the land. Raise this and cut gas from the ground to Sophie and weld the plate which has rectangular section or T-shaped section which has required thickness and height in the longitudinal direction of the ingot base material (outer plate) to the required size. As shown in FIG. 6, the tip of the crater is kept substantially parallel to the weld thickness portions C at both ends of the lounge B, which are arranged at a predetermined distance on the base material (outer plate) A. In addition, gas cutting was used to produce and collect the plates.

As a result, the operating speed at the time of gas cutting is slow, the amount of gas and labor cost required for cutting per hour is high, and the slack caused by gas cutting occurs, and the total weight of iron at the time of dismantling is greatly reduced due to slack, and the lounge is dismantled. If the base material (outer plate) is reused, it will not be possible to make uniform and flat melt cutting. Therefore, leave uneven welded portions on the upper surface of the base material, and do not add work such as smooth grinding or gas smooth melt cutting in the later process. There was a defect that must be made.

In the prior art, since the gas amount and labor cost required for gas cutting of the lounge are expensive, and there is a defect that cannot be flat melted cutting, the present invention slides the cutting machine horizontally on the plate to weld the glass to the lounge. The purpose of the present invention is to improve the work efficiency by press-cutting and cutting the weld bar of the plate, and to provide a uniform and high quality plate at a low price.

The cutting machines having a shear angle of about 5 ° are opposed to each other, and when the cutting machine is equipped with a bed equipped with a lifting device, a plate having a plurality of lounges is placed on the bed to raise the bed. Press-cutting both ends of the plate to the lower surface of the cutting machine and the upper surface of the bed, and slide the cutting machine horizontally on the plate while elongating the shaft bar associated with the cutting machine to press-cut and cut the weld skin of the lounge.

The bed is raised by placing a plate on which a plurality of lounges (13a) and (13b), which are divided and divided into required sizes on the bed, are raised, and the plate is pressed against the lower surface of the cutting machine and the upper surface of the bed to connect the cutting machine. In order to alternately extend the shaft bar, the cutting machine having a shear angle of about 5 ° back and forth slides the plate horizontally and presses the plurality of lounges 13a and 13b so that the lounges 13a and 13b are moved inward from the outside. While cutting the tip in a circular arc shape toward the end, the cutting machine slides the plate horizontally to smoothly cut the weld surface of the plate surface, and is pressed by the cutting machine lower surface and the bed upper surface. Because of the pinching, the sheet forms a flat shape.

In addition, it is possible to remarkably improve the work efficiency because a plurality of lounges can be cut while alternating cylinders.

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing a cutting device of a lounge of the present invention, and FIG. 2 is an explanatory view showing a conveyance state of the lounge.

As shown in FIG. 1, it is mounted on both ends of the baseplate 1. As shown in FIG. A cylinder support (3) (3) supporting the hydraulic cylinder (4) is fixed to the fixed base sheet (2), and the cylinder support (3) and (3) are connected in a transverse direction with a connecting frame, and the hydraulic cylinder is installed. The rear portion of the cutting machine 6 is joined to the tip of the shaft bar 4a of (4) to form a horizontal cutting device 7, and the space portion on the base plate 1 positioned between the base sheets 2 described above. Hydraulic jacks (8) and (8) are installed in the side, and a flat plate-mounted plate (9) is fixedly attached to the upper surfaces of the hydraulic jacks (8) and (8) to form a bed (10) freely lifting up and down. The cutting device of the lounge is configured by combining the horizontal cutting device (7) and the free lifting bed (10).

Referring to the state of use and operation of the lounge of the present invention, as shown in FIG. 2, a plate 12 having a plurality of lounges 13, which is divided into required sizes on the conveyance trolley 11, is placed. As shown by the arrow P on the bed 10 of which elevation is as high as the conveyance trolley 11, the board | plate material 12 is supplied and supplied.

Next, the hydraulic jacks 8 and 8 are raised to press and hold both ends of the plate 12 on which the plurality of lounges 13 are welded to the upper surface of the plate mounting base 9 and the lower surface of the cutting machine 6 and 6. Let's do it.

Subsequently, as shown in FIG. 3, the cutting machine 6 fixes and attaches the rectangular cutting edge 6b which has a rectangular cross section under the horizontal one side edge of the sheet | seat 6a of the cross section L, and is fixed. At the inner edge of the sheet 6a, one end of each rectangular shape was cut off. A plurality of (4) ribs 6c in shape are fixed and reinforced, and a cutting machine 6 having a shear angle of 5 ° is formed as a ratio of the front width 5 and the rear width 3.

As shown in FIG. 4, both ends of the plate 12 having the lounges 13a and 13b fixed to the upper surface of the plate mounting base 9 and the lower surface of the cutting machine 6 are pressed and squeezed as indicated by the arrow U. The shaft bars (4a) (4a) fastened to the rear of the cutting machines (6) and (6) are alternately operated with a cylinder pressure of about 140 kg / cm ² .

As shown in FIG. 4 and FIG. 5, the cutting machine 6, 6 presses the edges of the lounge 13a, 13b on the board 12 inward by sliding the top surface of the board 12 horizontally, and welding it. In addition to cutting the flesh portion 13c, the cutting blade 6b cuts and removes the weld portion 13c.

Since the cutting edge of the lower surface of the cutting machine slides the plate horizontally, the weld strips on the upper surface of the sheet are smoothly removed and pressed together by the pressing surface of the lower surface and the bed of the bed. By operating the shaft bar alternately, it is possible to cut a plurality of lounges, thereby significantly improving work efficiency and providing a good flat plate of uniform quality at a low cost.
