BACKGROUND OF THE INVENTION
Field of the Invention
The present invention is generally directed to a forming-and- cutting method and device for producing vinyl tile with rolled edges, and more particularly, to a method and device to produce vinyl tiles with rolled edges in a single integrated operation.
Description of the Related Art
The method for cutting vinyl tiles generally uses a hydraulic press to directly press-cut vinyl tiles, as show Figure 1.. First, uncut vinyl tile 15 that has been rolled and embossed is put on a lower die 14, and a piston rod 11 driven by a hydraulic system pushes an upper die base plate 12 to press downward. A cutting die 13, screwed to . the upper die base plate 12, is constructed with a blade seat 131 and four cutting tools 132 based on the size to be cut. The blade seat 131 screwed to the upper die base plate 12 and the four cutting tools 132 are screwed to the circumference of the blade seat 131. Therefore, as shown in Figure 2 (b) , when the cutting die 13 presses downward, the cutting die 13 cuts the uncut vinyl tile 15 to produce vinyl tiles 16 of the size designated by the cutting die 13 and the lower die 14. The vinyl tiles 16 cut by this method do not have rolled edges, as shown in figure 2 (c) . In order to have the same level of pavement quality as ceramic tiles, the method for producing vinyl tiles with rolled edges generally comprises two steps: first, a blade is used to produce vinyl tiles without rolled edges 16, and second, a manufacturing process, such as milling and/or grinding, is used to produce the rolled edges of vinyl tiles. This process requires a lot of time and labor.
Summary of the Invention
The present invention aims to provide "a forming-and-cutting method and device for producing vinyl tiles with rolled edges" . The invention is generally a forming-and-cutting method and device for producing vinyl tiles with rolled edges, and more in particular, a method and device for producing vinyl tile with rolled edges in a single integrated operation.

Detailed Description of the Preferred Embodiment
Figure 3 is a construction drawing of the press forming-and- cutting machine for producing vinyl tiles with rolled edges in accordance with the present invention. This press forming-and- cutting device comprises mainly a hydraulic cylinder 21, an upper die bracket 22, an upper die base plate 23, an upper die base platform 24, an upper press forming-and-cutting die 3 and a lower die (including: lower die plate 41, damper 42, and lower die base plate 43) . The upper press forming-and-cutting die 3 shown in Figure 4 comprises mainly a blade seat 31, a blade 32, a press forming die 33, a linear bearing set 34 and a disk spring 35. The press forming die 33 shown in Figure 5 comprises mainly the die plate 331 and the ejector device (including: ejector 336, ejector spring 337 and ejector nut 338). In Figure 5 (a) , a cylindrical groove 333 is machined in the center of the plate 331, four threaded holes 334 are evenly distributed around the grooves, four bolt holes 332 for die hanging are machined at the center of four edges, and four spot-faced holes 335 are drilled in the four corners' on the die plate 331. As shown in' Figure 5 (c) , the ejector devices (including: ejector 336, ejector spring 337 and ejector nut 338) are embedded in the spot-faced holes 335, where each ejector 336 is put through a corresponding spot-faced hole 335, is compressed against the ejector spring 337, and then is fixed by screwing to the ejector nut 338. In Figure 5 (d) , outward-tilted triangular protruding slope 339 is used to produce rolled edges, and the length and slope of this triangular slope are the length and slope of the rolled edges.
Moreover, Figure 6 shows the structure of the press forming- and-cutting die 3 designed in this invention. The round bar 341 of the linear bearing is mounted on the cylindrical groove 333 in
the center of the die plate 331 by screwing to the threaded hole 334 with bolt 342. The slide block 343 of the linear bearing is mounted in the spot-faced hole 234 of the upper die base plate 23 by screwing with bolt 344. Thus the press forming die 33 can move vertically relative to the upper die base plate 23. Two disk springs 35, based on the force needed for pressing rolled edges, are mounted on the round bar 341. Four bolts 330, passing through the spot-faced holes 233 of the upper die base plate 23, are used to bolt these two disk springs 35 to the threaded hole 332 on the die plate 331. Thus the press forming die 33 is hanging under the upper die base plate 23 with a tension force of the disk spring 35. The blade seat 31 is bolted to the upper die base plate 23 with bolt 311 and then the blade 32 is screwed to the blade seat 31 with bolt 321 with the tips of the blade lower than the press forming die 33. The upper die base plate 23 with press forming- and-cutting die 3 mounted is then bolted to the screw die bracket 22 with bolt 231.
The forming-and-cutting method and process for producing vinyl tile with rolled edges of this invention are shown in Fig. 7. There are four major steps: (1) Feeding stock 51, uncut vinyl tile that has been rolled and embossed is positioned on the lower die 41 of the press. (2) Pressing rolled edges 52, the piston rod 21 of the hydraulic cylinder driven by the hydraulic system push the upper die base plate 23 and the press forming die 33 downward such that the triangular protruding slope of the press forming die 33 first touches the vinyl tile stock and forms the desired size and slopes of rolled edges. At this time, the ejector 336 on the press forming die 33 is compressed. (3) Cutting 53, as the hydraulic cylinder continues pushing downward, the press forming die 33 finally touches the vinyl tile stock and the disk spring 35 that can sustain the designed force is compressed, thus keeping the press forming die 33 still. The blade 32 presses downward relative to the press forming die 33 to cut the vinyl tile with rolled edges to size the blade 32 and lower die 41 are designed to produce. (4) Ejecting and returning, raising the piston rod 21 of the hydraulic cylinder to lift the press forming die 33 and return
it to its original position. At the same time, the cut vinyl tile is separated from the press forming die 33 by the ejection of the ejector 336 of the press forming die 33. Thus the end product of the vinyl tile with rolled edges 61, as shown in figure 8, is produced.
In sum, the forming-and-cutting method and device for vinyl tile with rolled edges in accordance with the present invention can effectively press and directly cut out the vinyl tile with rolled edges in a single integrated operation, thus improving upon the conventional two-stage manufacturing methods and devices that require more time and labor.
Now that the invention has been described,
