Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a blanking sheet for press-

The present invention relates to a cleaning facility, which is a pretreatment process in a blank sheet press processing facility, and more particularly, to a cleaning facility in which a cleaning facility is installed directly on a floor of a facility without pits, The present invention relates to a cleaning apparatus for a blank sheet for press working which can reduce the manufacturing cost by simplifying the blank sheet.

Generally, in the operation of press-forming a panel, a blank sheet as a steel sheet is transported and conveyed through a conveying conveyor to perform cleaning, which is a pre-processing step of press processing in a cleaning facility. Then, in order to precisely perform press- Is completed, a blank sheet, which is a steel sheet, is formed into a required shape in a press facility to obtain a desired panel product.

In the press line of the blank sheet, a cleaning facility for cleaning the supplied blank sheet, which is one of the pre-processing processes, is installed in the operation line. The cleaning facility of the conventional blank sheet is provided with a cleaning facility installed in the up- Is installed in a pit formed in a space lower than the floor of the factory and is used to adjust the rising and falling of the washing facility by using the up and down screw jack of the up-down device. Such a washing facility of the conventional blank sheet, The manufacturing cost of the equipment is increased naturally because of the cumbersome work. In addition, there is a problem that the equipment mounting ability for aligning the work transfer line of the blank sheet is naturally complicated.

Accordingly, it is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide a method of manufacturing a press sheet for a blank sheet, And it is an object of the present invention to provide a cleaning apparatus for a blank sheet for press working which can lower the unit cost.

In order to accomplish the above object, according to the present invention, in a pretreatment process for cleanly cleaning a blank sheet, which is an iron plate, before putting the blank sheet into a press facility, the cleaning frame for supplying the cleaning oil is moved up and down by the up- Wherein the upper cleaning frame of the cleaning frame is connected to an up-down screw jack installed in a connection bracket fixed to the periphery, the upper and lower cleaning frames of the cleaning frame are installed at upper and lower portions along the guide shaft, The upper cleaning frame and the lower cleaning frame are integrally or separated from each other by a rotary clamp.

The cleaning facility for the blank sheet for press working according to the present invention can be installed without installing the pit which is a special pit on the floor of the factory at the time of installing the facility, so that the manufacturing cost of the facility can be lowered by a simple structure .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing a washing facility for washing a blank sheet of a steel sheet, which is provided between a conveying conveyor 100 of a blank sheet and an aligning device 200 and is a pre-pressurizing process, (Not shown in the drawing) is fed by the conveying conveyor 100 in the direction of arrow A to be inserted between the upper and lower cleaning frames 1a and 1b of the cleaning facility. The blank sheets inserted into the upper and lower cleaning frames 1a and 1b Cleaned by washing oil as known in the art, and then moved to the aligning device 200 disposed on the same work line, aligned and precisely put into the press facility to perform steel plate panel molding.

That is, according to the present invention, in the pretreatment process for cleanly cleaning the blank sheet, which is a steel sheet, before the blank sheet is put into the press facility, the cleaning frame for feeding the blank oil is moved up and down by the up- In the cleaning facility, the upper cleaning frame 1a of the cleaning frame 1 is connected to the up-down screw jack 4 of the up-down driving part 3 installed in the peripheral mounting bracket 2, The upper and lower cleaning frames 1a and 1b of the frame 1 are divided into upper and lower portions along a plurality of vertical guide shafts 7 provided on a support 6 of a floor 5, The lower cleaning frame 1b is in a locked state or a separated open state integrally connected by the rotary clamp 8.

3, the up-down driving unit 3 includes a motor 9 fixedly mounted on the floor 5, both gear boxes 11 connected to the driving shaft 10 of the motor 9, And the screw jack 4 of the up-down driving part 3 is connected to the upper cleaning frame 1a of the cleaning frame 1 and the connection bracket 2 It is directly connected by mediation.

Therefore, when the motor 9 is driven, the power is transmitted to the screw jack 4 through the gear box 11 so that the entire cleaning frame 1 moves in the direction of arrow B as shown in Fig. So as to move up and down.

As shown in FIG. 3 (B) and FIG. 5, the upper and lower cleaning frames 1a and 1b can be operated in the unlocked state separated from the locked state integrally by the rotary clamp 8 5 (C) shows a locking structure in which the upper and lower cleaning frames 1a and 1b are connected to each other by the operation of the rotary clamp 8. FIG. 5 (D) shows the upper and lower cleaning frames 1a and 1b, Which is separated by the rotary clamp 8.

When the rotary clamp 8 as shown in Fig. 5 (C) locks, the upper and lower cleaning frames 1a and 1b are integrally operated together. When the rotary clamp 8 is released as shown in Fig. 5 (D) The frames 1a and 1b are configured to operate separately from each other.

Next, the operation of the present invention will be described.

The blank sheet, which is a steel sheet carried along the direction of arrow (a) in Fig. 1, is put into the upper and lower cleaning frames 1a and 1b of the cleaning frame 1 and cleaned by washing water as is well known, (200) and wait for the press facility to be inserted.

2, the cleaning frame 1 made up of the upper and lower cleaning frames 1a and 1b is entirely raised by the action of the screw jack 4 of the up-down driving unit 3, The blank sheet is directly fed into the aligning apparatus 200 through the bypass conveyor 12. The upper and lower cleaning frames 1a and 1b are integrally connected to each other by a rotary clamp 8 as shown in FIG. 5 (C), and the operation of the screw jack 4 of the up- As shown in Fig. 2, or can be lowered as shown in Fig.

The upper and lower cleaning frames 1a and 1b of the cleaning frame 1 for maintenance or internal inspection are removed from the lower cleaning frame 1 The upper cleaning frame 1a is lifted up on the basis of the upper and lower washers 1b and 1b. At this time, when the rotary clamp 8 operates the up-down driving unit 3 in the released state as shown in FIG. 5D, 3, the screw jack 4 of the upper cleaning frame 1a is lifted up along the vertical guide shaft 7 only.

When the inner cleaning operation of the upper and lower cleaning frames 1a and 1b is completed, the upper cleaning frame 1a is returned to its original position. When the rotary clamp 8 is switched to the locked position as shown in FIG. 5C, (1a, 1b) are designed to operate integrally.

The present invention is a cleaning facility for cleaning a blank sheet as a steel sheet before press forming, and it is not necessary to separately construct a pit on the floor of a factory when installing the facility, and the manufacturing cost of the facility can be reduced by simplifying the structure, Respectively.
