6 Claims. 1 This invention relates to piercing, holing, perforating, or coring mechanisms, and particularly to a device for partially perforating or piercing a material normally difficult to make clean-cut, accurate, and symmetrical holes therein.
Devices or punches for making holes or apertures in materials are well-known, the present invention, however, performing an operation whereby a multiplicity or plurality of apertures are made in a material in which it is difficult to cut or punch smooth, uniform, and sharp holes. It has been found that the desired type of opening cannot be made simply by in serting a pointed punch or rod and withdrawing it from the material. holes partially through the material are desired, the simultaneous making of the holes has been difficult to perform with known equipment.
With the present invention, not only are a large number of clean-cut holes possible, but
"they are uniform and may be of diiierent shapes. The particular material being cored is Fiberglas which has been molded with a resinous binder, or other similar type of binder, into squares or tiles of rectangular form, and which have been found to have desirable sound absorbing characteristics. By the use of such tile, acoustic absorption can be increased, and the sound absorption characteristic may be controlled by the number, diameter, spacing, and depth of the holes in the material. The material has several important features; namely, it
, is fire proof, it may be decorated by painting or otherwise, it is termite-proof, and it is almost indestructible by the elements. It has been found, however, that by coring the material as mentioned above, it is provided with increased sound absorbing qualities and may be given a predetermined sound absorbing characteristic within the audio range. Furthermore, it can be repeatedly painted with any type paint after punched, without any decrease in sound absorption.
The principal object of the invention, therefore, is to facilitate the coring of a solid or felted material.
Another object of the invention is to provide an improved coring device for Fiberglas blocks or tile.
A further object of the invention is to provide a device for punching a large number of holes in a Figerglas tile block in which the holes are uniform and clean-cut.
A still further object of the invention is to pro- Since a large number of vide an improved coring device for Fiberglas, mineral, or rock wool fiber tile.
Although the novel features which are believed to be characteristic of this invention will be pointed out with particularity in the appended claims, the manner of its organization and the mode of its operation will be better understood by referring to the following description read in conjunction with the accompanying drawings, forming a part hereof, in which:
Fig. 1 is a perspective view of the coring or punching device of the invention.
Fig. 2 is a plan view of the device shown in Fig. 1.
Fig. 3 is a cross-sectional view of the invention taken along the line 33 of Fig. 2.
Fig. 4". is a perspective view of the product obtained after passing through the invention.
Fig. 5 is an enlarged cross-sectional view showing the invention in a coring position.
Figs. 6 and 7 are detailed views showing modifications for heating the punching rods, and
Fig. 8 is a perspective view of varying shapes of punching rods which may be used in the invention.
Referring now to the drawings, in which the same numerals refer to like elements, a base plate 5 is mounted upon suitable legs or posts 6, and under which are attached a pair of hydraulic cylinders l. Slidably mounted on four posts [0, the posts being mounted on the base plate 5, is an index-pressure unit 8 including a backing plate i2 and insulator plate 25 and a punch rod actuating and heating unit 13. The plate 12 is of material having a very low thermal expansion. Between the plate 12 and the base plate 5 are studs l5 with their associated nuts I6 and surrounded by coil springs IT. A pair of piston rods 20 pass through the base plate 5 and the plate [2, and are adapted to pull the plate l2, and, consequently, the plate 25 toward the base plate 5 when air or other hydraulic fluid is forced into the cylinders through conduits 22. When the hydraulic pressure is released, the springs I! will raise the plate 12 to the nuts 16 of the studs l5.
The plate. l2 and plate 25 are fastened together by bolts M, or other suitable means, and are provided with a plurality of indexing holes 24. The plate 25 is formed of a number of laminated sheets of asbestos or similar heat insulating material. Attached to the base plate 5 to position the article 30 to be perforated, are guides or runners 3|, these guides having a height slightly less than the width of the block or tile 30, so as "48 by machine screws 49.
cable or cord 62'.
.ing of the material.
heights may be used for other materials. A simi-.
lar back stop is provided to further position or align the material.
The Perforating or die unit l3, as shown in Figs. 1-5, inclusive, comprises a plurality of punch rods 33 having heads 34 positioned between a metal rod holder plate 36 and a heat conducting plate 31, the latter being of a material such as copper, which has good heat conductivity. To heat the plate 31, a plurality of heating wires or conductors 3B are molded or threaded in the heating plate 39 held in position by a metal plate 40. The heat conducting plate 37 and the heating plate 39 are fastened to rod holder plate 36 by a plurality of machine screws such as shown at 4!.
Above plate 43 is a heat insulating pad 33, the .pad and plate 40 being fastened to a press shoe Electrical energy is supplied to the heating conductors through a Thus, as the pad 39 is heated, the heat is distributed to the heads of the punching rods 33 by the conductor plate 31, so that "the rods may become heated to any desired temperature required.
on the top surface of the press shoe 33, is a yoke 4'4, in which a connecting rod 45 is attached, the other end of the rod being connected to the crank 43 of a shaft 41. Thus, rotation of the shaft 4? will oscillate the punch or die unit l3, and, consequently, the punch or perforating rods 33. An insulating pad'52 is attached to plate 36 by screws 53. To orient the punch rods 33 accurately with respect to index-pressure plate unit 8, the rod holder plate '36 is attached to press shoe 48 by precision sleeve spacers 55 through which stripper bolts, such as shown at 35, pass. Nuts 66 are used on the bolts 65. Surrounding the die unit I3 is further insulating material 61.
In'operati'on, the Fiberglas block 30, or other material to be apertured, is inserted between the guide runners 3i, hydraulic fluid is introduced in the cylinder 1, and the index and pressure plate combination 8 is brought down on the block 30. Theplate 8 may first compress the block 30 or the plate 8 may be forced down by the unit I3 as it is lowered, whilethe hydraulic unit or other locking device maintains it in position. It is only necessary that the block 33 be under pressure during the coring operation. The shaft 41 is then rotated and the rods 33 pass in and out of block 33 to a predetermined depth approxichrome platecbare at this temperature, the contact surface of. plate is approximately 350 degrees F. i
There are several features of the device which enter into the making of the clean-cut holes in the fibrous material: (1) Pressure on the fiber block creates an increased density therein durin the coring operation to produce sharp perimeters for the'holes; (2) The guiding of'the punch rods 33 by theindexpressure unit 8 'keepsthe axes of therods parallel at all times; (3 The heating of the die rods softens the material and binder to allow-them to reform to make a smooth wall for the holes; (4).The oscillation of the punch rods in the holes reforms thefibres by repeated pierc- All of these features are that Fiberglasmay be cored with clean, uniform V holes at uniform distancesapart very effectively. Althoughthe rods, which may be of copper and provided in the device rality of holes described above, and cored blocks are produced which have a plurality of uniform and clean-cut holes.
Referring now to Figs. 6 and 7, the perforating rods 33 may also be heated differently from that shown in Figs. 1 to 5, inclusive. In Fig. 6, the rod 33 is heated from a direct current energy source, such as 50, through protective resistors 5!. In this manner, the electrical energy Passes directly through the head 33. Therod 33 could also be split and the slot filled with a dielectric material so that the electrical current would actually pass through the sides of the rod, the rod acting as a resistor to electric current and thereby becoming hot. It is understood that alternating current may also be used. An inductive heatin method is shown in Fig. 7, whereby the induction coil 54 surrounds the rod. The coil 54 may travel with the rod or the rod 33 could pass through an opening in the coil.
Referring now to Fig. 8, a cylindrical type of rod 33 is shown, together with a squareor-rectangularly shaped rod 53, a triangularly shaped rod 5?, a crescent shaped rod 58, and a slot rod 59. These rods will make holes of the shape indicated at 6%), 61, 32, 63, andfi-l. The type or shape of core hole 33 can be successfully made with the invention, which isnot practical with coring or perforating devices now; known in the art. It is to be understood that any combination of these rods and other shapes thereof may, be used to form pleasing patterns, such as rosettes, stars, and similar geometric designs, for decorative purposes.
