1. Field of the Invention
The present invention relates to a system manufacturing composite aluminum panels continuously by using metal (aluminum) cores being expanded continuously in manufacture of composite aluminum panels.
2. Description of the Related Art
Up to now, for manufacture composite aluminum panels inserted honeycomb cores, honeycomb type metal (hereinafter refer to as aluminum) cores are expanded in a certain length by a manual expanding device, hot-melt film layers are put on the upper and the lower sides of the expanded cores and on the film layers aluminum plates are put, the objects are pressed in hot presses, to give composite aluminum panels.
But in this case expanding devices of aluminum cores should be operated manually and thus the cores can not expanded continuously.
Accordingly the standardized panels can not be manufactured continuously.
Now, referring to the accompanying drawings, a method for expanding cores for composite aluminum panel by the conventional device for expanding cores and a conventional process for preparing panels by using the expanded cores will be described as follows.
As shown in FIG. 5, a fixing part Fa fixing a left end of pre-expanded raw material 1001 for honeycomb type cores comprising a supporter 300 fixed on the upper one side of a base 200, a number of air pressure cylinders 400 ascending and descending on the supporter 300, a stair type bracket 600 fixed on the lower ends of rods 500 of the cylinders 400, a holding rod 900 for taking needle rods 700 mounted on the bracket 600 and having a number of holes 800 capable of inserting and drawing needle rods 700 for fixing on a number of holes 1002 of honeycomb type cores; a transferring part R comprising the supporter 300, a number of the air pressure cylinder 400, the stair type bracket 600 and a holding rod 900 for taking needle rods having a number of inserting and drawing holes 800 identical to those of the fixing part Fa, and a pinion gear (not shown) established on the lower end of the supporter 300, engaging with a rack 1003 established on the upper both sides of the base 200 to transfer right and left; and plate 100 for expanding the honeycomb type core formed between the fixing part Fa and transferring part R.
But to manufacture the expanded honeycomb type cores from raw material for core by the conventional device for expanding honeycomb type core, after a number of needle rods 700 are inserted perpendicularly in the inserting and drawing holes 800 for the needle rods of the fixing part Fa manually, by means of ascent and descent of ascending and descending cylinder the bracket 600 fixed on the lower part of the cylinder is gone up and come down to ascend and descend the holding rod 900 for taking needle rods 700 fixed on the bracket 600, and by means of ascent and descent of the holding rod 900 the lower ends of the needle rods 700 inserted in the inserting and drawing holes 800 of the holding rod 900 are fixed, by means of inserting, in the holes 1002 of the honeycomb type core expanded partially in left end of raw material for the honeycomb type core.
At this time, by means of the pinion gear (not shown) fixed on the lower end of the transferring part R engaged with the rack established on the upper both sides of the base 200, the transferring part R is transferring manually to lie adjacent to the fixing part Fa, then the lower ends of the needle rods 700 inserted in the inserting and drawing holes 800 for needle rods of the holding rod 900 fixed on the transferring part R are inserted in the holes 1002 of the honeycomb type core expanded partially or manually of the right end of the raw material (core-raw material) 1001 for the honeycomb type core and the transferring part R is transferred manually in the right direction to give expanded honeycomb type core from the raw material 1001 for the honeycomb type core.
However, in the conventional device, the needle rods 700 for taking the core-raw material 1001 should be inserted manually in the inserting and drawing holes 800 for needle rods, the transferring part R also should be transferred manually in right and left, length and width of the honeycomb type core manufactured by the device also are restricted, that is, in one device cores having restricted length and width only are manufactured.
Accordingly this device has faults that various sorts of cores having different length and width cannot be made.
Furthermore, in manufacturing composite aluminum panels by using honeycomb type cores expanded by this device because all of honeycomb type cores, hot melting films and aluminum plates as raw materials for manufacturing the panel should be layered only manually, the raw materials cannot be layered in the same mode.
Accordingly by means of the above-mentioned conventional device standardized articles cannot be produced and also long and large panels cannot be produced continuously.
