Description

Disc processing device for single-layer lamination {A MANUFACTURING APPARATUS OF STACKING VENEER SHEETS FOR CIRCULAR PLATE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk processing apparatus, and more particularly, to an apparatus for processing a disk, which is a heat cutting member used in a high voltage transformer using a single plate lamination agent.

 In general, in order to reduce the power loss during transmission of electricity generated in the power plant through each transformer, high voltage, especially high voltage, such as 22,000V, 154,000V, 345,000V. Therefore, the peripheral parts of the transformer to maintain such a high voltage is made of an insulation material, and for this purpose, a phenol resin board having a heat resistance temperature of 105 ° C. or a wooden end plate impregnated with a phenol resin was used. Due to this use is almost eliminated, instead, a single plate laminate made by stacking a plurality of laminates formed by thinly slicing wood is used as an insulation.

Currently, the supporting members made of plate type supporting coil windings of transformers, upper and lower pressers, and wire supporting bars made of rod type, and insulating nuts and insulating bolts joining them are laminated wood laminates. The use of is dominant.

This is due to the explosive increase in electric power demand, so long distance transmission and bivariate are mostly used. In order to minimize the loss of current at the power plant, special high voltage transformer should be used. Therefore, special high voltage transformer is used. With various insulation materials, single-layer laminates as transformer components and supporting components are used, and their usage is gradually increasing due to the explosive increase in electric power demand due to the superiority of their functions.

FIG. 2 is a perspective view showing a master plate processing apparatus for single-layer laminate according to a preferred embodiment of the present invention. FIG.

As shown in FIG. 2, the apparatus for processing a single plate laminate according to the present invention includes a rotating plate 100, a jig unit 110, a frame 200, a center support unit 300, and a grooving machine 400. Is done.

First, the rotating plate 100 is installed horizontally on the ground where the end plate laminate 10, which is a processing material, is mounted, and is rotated through a drive motor (not shown). The rotary plate 100 is provided with a jig portion 110 for fixing the plate-shaped end plate lamination 10 to the upper surface.

The jig unit 110 is recessed groove 112 formed in the center direction on the upper surface of the rotating plate 100, the lower portion is constrained to the locking jaw formed in the recessed groove 112, the upper nut (N) It is preferred that the screw portion 114 is coupled to. The jig unit 110 is installed on two or more of the rotating plate to allow the material 10 to be stably fixed in the rotation process.

Therefore, since the screw portion 114 can be moved along the recessed groove 112, it is possible to fix the material having various diameters.

In addition, a wooden safety plate 102 may be installed on the upper part of the rotating plate 100 to prevent the rotating plate from being damaged or the cutting part of the grooving machine or the like being damaged.

Next, the frame 200 is installed on the upper side of the rotating plate 100, the center support portion 300 and the grooving machine 400 is installed on the frame 200.

The center support part 300 presses the center of the material 10 fixed to the rotating plate 100 so that the cutting process can be made around the center, and the support shaft 310 is the material 10 using a hydraulic pressure. To pressurize the top surface.

Next, the grooving machine 400 has a moving part 404 capable of moving the cutting part 402 which is horizontally moved along the rail 10 installed on the frame 200 and is vertically movable. Should be included.

The grooving machine 400 may form a recess in the material. When the processing is completed, the grooving machine 400 cuts the material in a circular shape.

In addition, the frame 100 may be further provided with a drill 500 that is vertically movable.

The drill unit 500 serves to form a through hole in the material 10, and should include a hydraulic machine in which the drill is movable vertically.

In addition, the nature of wood processing, air must be supplied to reduce the sawdust treatment and heat generated during the processing.

Accordingly, the grooving machine 400 includes a cutting unit 402, a moving unit 404 for moving the cutting unit 402 up and down, and an air supply for supplying air to an end of the cutting unit 402. It is preferable to comprise a part.

Figure 4 is a perspective view showing a master plate processing apparatus for single-layer laminate according to another preferred embodiment of the present invention.

As shown in FIG. 4, the air supply unit is provided with an air nozzle 710 through which the air supplied through the air supply device can be injected. Similarly, the air nozzles 720 and 730 may also be installed in the center support unit 330 and the drill unit 500. This can be installed.

In addition, the rotating plate 100, the center support portion 300, the grooving machine 400 and the drill portion 50 allows the user to be continuously processed through the operation panel 600, and control the operation Insulation discs can be produced automatically by allowing them to be made automatically.

The specific use aspect of the disc processing apparatus for single-layer laminated materials which concerns on this invention is demonstrated.

Figure 3 is an operation of the original plate processing apparatus for monolayer laminate according to an embodiment of the present invention.

As shown in (a) of FIG. 3, when the single layer laminate 10 is fixed to the upper surface of the rotating plate 100 through the jig part 110, the center support part 300 is operated to support the support shaft 310. It comes into contact with the central upper surface of the material. However, in order to prevent damage to the material due to the pressing of the support shaft 310, the reinforcing member 20 may be placed on the center of the material so that the support shaft 310 is in contact with the reinforcing member.

When the process is completed, as shown in (b) of Figure 3, the rotating plate 100 is rotated, the grooving machine 400 is moved along the rail 10 to the correct position and then moving the moving part 404 Through the cutting portion 402 is in contact with the upper surface of the material 10 to form the depression (2).

In addition, as shown in FIG. 3C, the drill part 500 is also vertically lowered to form through holes in the material. However, in the above process, the rotation of the rotating plate 100 should be stopped, and the through hole may be formed at a desired point by using the horizontal movement of the drill unit and the rotating movement of the rotating plate 100.

Finally, when the above process is completed, as shown in (d) of FIG. 3, the original plate 1 is cut from the raw material 10 using the grooving machine 400 while rotating the rotary plate 100.

As described above, the present invention has a main technical idea, and the embodiment described above with reference to the drawings is only one embodiment, so the true scope of the present invention should be determined by the claims.
