Definitions
- a die cutting block configured for cutting one or more sheets of paper is comprised of a base plate formed from low carbon steel plate.
- a steel rule blade is heat treated and toughened to a Rockwell C Hardness of approximately 40 following forming.
- the ends of the rule are aligned, clamped into position and welded together.
- the thickness of the base plate may vary depending upon the height of the steel rule.
- a design matching the outline of the steel rule design is cut into and through the base plate as with an electrical discharge machining (EDM) center.
- EDM electrical discharge machining
- the width of the design outline is machined to substantially match the width of the steel rule, within certain tolerances.
- the machining of the base plate results in at least two separate pieces.
- the first piece comprises the outside portion of the design outline and the second portion comprises the inside or "cut-out” portion of the design outline.
- the material removed during machining provides the space necessary to insert the blade therein so as to be ultimately held between the outside and inside portions.
- the die cutting apparatus is f-ormed by laying the outside portion of the base plate on a flat surface and positioning the inside portion within the base portion, also upon the flat surface.
- a preformed steel rule having a contour to substantially match the contour of the gap formed between the outside portion and the inside portion is pressed into the gap.
- the ⁇ steel rule is pressed until it is approximately flush with the back surface of the base plate. This is accomplished by pressing the steel rule until it abuts against the flat surface.
- FIG. 1A is a back view of a first embodiment of a die cutting apparatus in accordance with the principles of the present invention
- FIG. IB is a cross-sectional side view of the die cutting apparatus illustrated in FIG. 1A
- FIG. 2A is a cross-sectional side view of a second embodiment of a die cutting apparatus in accordance with the principles of the present invention
- FIG. 2B is a close-up detail of the die cutting apparatus illustrated in FIG. 2A
- FIG. 3A is a top view of a second embodiment of a preformed blade in accordance with the principles of the present invention
- FIG. 3B is a top view of a base plate for use with preformed blade illustrated in FIG. 3A in accordance with the principles of the present invention
- Such steel rule may be heat treated and toughened to a Rockwell C hardness of 40 following forming. It is desirable to provide an interference fit between the blades 24 and 26, and the surfaces of the base portion 12 forming the channels 20 and 22 for assembly purposes. That is, during the assembly process, after the base portion 12 is cut, the blades 24 and 26 are pressed into the channels 20 and 22, respectively.
- the interference fit allows the assembly to hold itself while the base portion 12 is bonded to the blades 20 and 24, as by spot welds, such as spot welds 28, 29, 30. and 31 formed on the back side 32 of the base portion 12, as by TIG welding.
- the spot welds may subsequently be partially ground away to provide a relatively flat back surface 32 to the die cutting apparatus 10. As better shown in FIG.
- FIG. 3A a steel rule blade 100 has been bent into a preformed shape, in this example a hexagon.
- the blade 100 is formed by first providing an elongate strip of steel, forming a desired contour in the blade 100 by forming bends 101, 102, 103, 104, 105 and 106 and then attaching the two opposing ends of the strip with a transversely extending weld 108.
- FIG. 3A a steel rule blade 100 has been bent into a preformed shape, in this example a hexagon.
- the blade 100 is formed by first providing an elongate strip of steel, forming a desired contour in the blade 100 by forming bends 101, 102, 103, 104, 105 and 106 and then attaching the two opposing ends of the strip with a transversely extending weld 108.
- a base plate 110 has been cut, as by EDM machining a channel 112 into the base plate 110, to separate the base plate 110 into an outer portion 114 and an inner portion 116.
- an inner surface 118 is formed on the outer portion 114 and an outer surface 120 is formed on the inner portion 116.
- Such inner and outer surfaces 118 and 120 respectively, define the contour of the channel 112 and are configured to substantially match the contour of the preformed blade 100, or vise versa.
- the width of the cut and the subsequent gap or channel 112 formed as a result of such cutting is such that the blade 100 can fit within the base plate 110 in the channel 112.
- the method 200 includes the steps of cutting 202 the base plate to form one or more desired channels having a particular contour or shape for receiving one or more blades therein. Such cutting may be achieved by an EDM machining process or other cutting methods known in the art.
- the cut or machined base plate is then placed 204 upon a support surface for receiving the pre-shaped or preformed steel rule.
- One or more segments of steel rule blade are shaped 206 into a desired contour.
- more than one segment may be joined together as by welding to form a single shape (as may be necessary for complex configurations where bending will not necessarily achieve the desired shape) or more than one segment may be shaped to form various contours to provide various cutting edges in the finished product, though not necessarily forming part of the same contour or shape .
- Each rule blade is then pressed 208 into the base plate until the non-cutting edge of the rule is substantially flush with the back side of the base plate.
- the rule is then attached 210 to the base plate as by spot welding or other methods of bonding or attachment known in the art.
- the first inner portion 306 lies within the outer portion 304 and the second and third inner portions 308 and 310 each lie within the first inner portion 306.
- Each of the portions 304, 306, 308 and 310 are separated by a respective blade 312, 314, and 316.
- a fourth blade 318 is provided in a elongate channel or slot 320 formed in the first inner portion 306, in this example to form the mouth of the smiley face.
- Such a blade 318 may be a straight edged blade or a perforation blade to form a perforation cut.
- the channels in the base plate 302 may form separate pieces, such as inner portions 306, 308 and 310, it is also part of the present invention to form channels 320 that form open sided contours as desired.
- the blade 318 can be inserted and attached to the base plate 302 as herein described. While the blades forming the interior cuts described herein have been illustrated as being comprised of elongate, thin blade members, it is also contemplated that such blade members may be formed from punch type members such as those found on paper punches and the like. For example, if it is desired to cut eyes out of a sheet of material that is being die cut into the shape of a person or animal, elongate posts may be received within the insert holding one of the blades. The elongate posts may then be provided with sharpened edges for punching a hole in the material being cut. Furthermore, the posts may be held in place by providing a hole in the base plate.
