BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building lattice-like exterior panel, and more particularly, to a chamfering device for building lattice-like exterior panel that can make chamfers of four corners of the exterior panel without defect.

In general, the exterior of a building is a tile or a coated paint on a concrete structure, and a slab or an exterior panel is attached on a steel structure. However, tiles and slabs have disadvantages such as detachment over time, and have a disadvantage that they have to be removed and disposed of when changing the exterior of a building.

Recently, the building is being renovated by repairing only the exterior through renovation such as remodeling, reforming, etc. without breaking down the old building which is not at the end of its life, repairing the interior and exterior of the building, and repairing the building as a whole through extension and renovation.

In the case of fixing the exterior of the building through renovation, an aluminum composite panel containing polyethylene material is inserted between aluminum and aluminum, or an aluminum panel made of only aluminum by inserting a honeycomb-shaped honeycomb core between aluminum and aluminum. Aluminum composite panels are not flame retardant, and there is a problem that fumes and poison gas are emitted due to polyethylene in the event of fire. In recent years, the strength of the aluminum composite panel is slightly lower than that of the aluminum composite panel. Mainly used.

In order to use the aluminum panel on the exterior of the building, a lattice frame is laid on the exterior of the building, and a hollow box-shaped aluminum panel made by processing as shown in FIG. It is easy to renovate and easy to install in new buildings. It is widely used for durability, light weight, and exterior appearance of buildings.

In order to manufacture a box-shaped aluminum panel as shown in Figure 1, first, each corner of the aluminum panel cut into a square of a certain size should be chamfered as shown in FIG.

It includes.

Inside the outer case 11 is provided with an inclined scrap discharge guide box 14 to freely drop the V-shaped scrap 70 generated when chamfered by the circular saw 33 as shown in Figure 6 and 7 An end portion of the scrap discharge guide box 14 protrudes outward from the outer case. Accordingly, the V-shaped scraps can be easily discharged and collected outside.

In addition, the outer case 11 is provided with a sawdust suction port 15 for sucking and discharging the sawdust scattered when chamfering. The sawdust suction port 15 is provided with a sawdust reducer (not shown) can suck the sawdust scattered inside the main body 10 during chamfering can keep the inside of the main body 10 clean.

And one side of the main body 10 is provided with an on / off control button 16 for supplying power to the main body 10, the lower portion is provided with a roller 17 to be easily movable.

On the other hand, the work table 20 is composed of a plurality of legs 21 and the top plate 22 is provided with an aluminum panel 50 is chamfered in all directions by the cutter 30 on the top plate 22. On one side of the upper plate of the work table 20, the pair of circular saws 33 are passed through the lower V-shaped cutout portion 23 is formed so as to chamfer the aluminum panel 50.

In addition, the worktable 20 is installed at both sides of the movable vertical stopper 24 and the V-shaped cutout 23 for determining the vertical position of the aluminum panel 50 to adjust the horizontal position of the aluminum panel 50. A movable transverse stopper 25 for determining is installed. The longitudinal stopper 24 is preferably composed of a rubber magnetic plate to move the removable.

As shown in FIG. 8, the horizontal stopper 25 is provided with a chamfer size adjusting opening 60, and the chamfering size adjusting opening 60 includes a support 61 attached to one side of the work table 20; An adjusting handle 62 having a screw shaft 621 which is screwed to the support 61; And the horizontal stopper 25 coupled to the screw shaft 621 and the horizontal stopper 25 while being moved back and forth along the guider 63 by the screw shaft 621 which is moved back and forth according to the rotation of the adjustment handle 62. ) Includes a pusher 64 for moving back and forth.

The effect of the chamfering device of the building grid type exterior panel of the present invention configured as described above will be described in detail.

As shown in FIG. 9, the user places the aluminum panel 50 on the workbench 20 and forms a corner at which the chamfer of the aluminum panel 50 is to be chamfered to the V-shaped cutout 23 of the workbench 20. It is set appropriately using the longitudinal stopper 24. That is, the horizontal stopper 25 is rotated by adjusting the handle 62 of the chamfer size adjusting opening 60 to adjust the position while moving the screw shaft 621 forward and backward, and the rubber magnetic plate of the vertical stopper 24 is attached and detached. Adjust the position. In this way, the position of the corner chamfer of the aluminum panel 50 is determined and set by the horizontal stopper 25 and the vertical stopper 24.

The corner of the aluminum panel 50 to be chamfered is accurately positioned on the V-shaped cutout 23 of the work table 20 using the horizontal stopper 25 and the vertical stopper 24, and then the control button of the main body 10. Press the on button of 16 to apply power to the main body 10, and when the operation pedal 40 is pressed, the air cylinder jig 13 is operated so that the piston 131 descends while the gripper 132 is made of aluminum. Press the edge of the panel 50 to hold the aluminum panel 50 does not move when cutting the chamfer.

Subsequently, the circular saw 33 rotates and descends, that is, as shown in FIG. 6, the air cylinder for elevating and operating the pedestal 34 provided with the circular saw 33 and the driving motor 31 for rotating the circular saw 33 ( As the piston 351 of the lower portion 35 is lowered, the pedestal 34 descends as shown in FIG. 7, and naturally passes through the V-shaped cutout 23 of the work table 20, while the corner of the aluminum panel 50 is V-shaped as shown in FIG. 9. The chamfer will be performed.

When the chamfering is completed by the driving of the circular saw 33, and the user releases the foot from the operating pedal 40, the circular saw 33 and the pistons 35 and 131 of the air cylinder jig 13 are raised. After the user places the four corners of the chamfered aluminum panel 50 as shown in FIG. 10 using the horizontal stopper 25 and the vertical stopper 24 set on the work table 20 in the same order as in FIG. 3. What is necessary is just to chamfer as mentioned above.

As described above, the chamfer is naturally formed by the circular saw 33, the air cylinder jig 13, and the V-shaped cutout 23, and the dents of the chamfers generated by chamfering with a hydraulic press as in the prior art, Quality defects such as cutting of the fold line are not generated, thereby increasing the yield of the product.

On the other hand, the V-shaped scrap 70 generated by the chamfer as described above, as shown in Figures 6 and 7, fall freely falling into the inclined scrap discharge guide box 14 while the freely falling out of the scrap discharge guide box Collected through the end of 14.

And sawdust is scattered in the main body during chamfering, the sawdust is scattered by the sawdust reducer (not shown) through the sawdust outlet 15 to maintain the cleanliness of the interior of the body.

As seen through the configuration of the present invention and its operation, the present invention can be smoothly performed by chamfering the four corners of the aluminum panel using the circular saw and the V-shaped cutout of the workbench through which the circular saw passes. Since defects such as crushing of chamfered portions or cutting of folds of chamfered portions are not generated, production yield is increased, thereby minimizing losses caused by defective products.
