Description

THIN SKIN FOR USE IN A PRESS DESCRIPTION OF THE INVENTION A thin die adapted for use in a press is described and, more particularly, a thin die adapted for use in a press is described, a system including a thin die and a press, and a method for manufacturing a thin die adapted for use in a press. Cutting dies and sheet presses are used to cut various patterns of laminated materials. The presses may take the form of a die platen press or a roll die press. The presses are designed to apply uniform pressure to a die to cut through a sheet or a plurality of sheets simultaneously. The dies can also be used to stamp images on laminated materials. Typically, the sheets are placed between the die and a tool holder or cushion cutting cushion, with the steel rule and the die extending through the sheets and slightly toward the cutting tool holder when pressure is applied to the die. The die-cutting presses are used commercially, as well as by consumers. Typically, a variety of shapes are provided by the various available dies. For example, typical dies include shapes that vary from letters in the alphabet, numbers, and various other shapes, such as moons, stars, animals, trees, and various other shapes. Typically, the dies include a base material, such as laminated wood or plastic, which houses a steel rule that is formed in the desired cut shape. A rubber material is then glued to the laminated wood or plastic base so that the rubber extends over the height of the sharp edge of the bent steel rule form, so that the rubber protects the steel rule and acts as an ejector means for ejecting the cut sheet material from the steel rule after the cutting process. A thin die adapted for use in a press is disclosed. The die is described herein including a base or support portion that provides rigidity to the die assembly. The base includes an indentation defining a flange around the peripheral edge of the base. A thin die lodges in the indentation of the base and the thin die adheres to the indentation of the base by means of an adhesive. The thin die is placed in the indentation of the base so that the raised or raised portions of the thin die move away from the indentation in the base to allow the thin die to cut into and stamp a laminate. The ejection foam is adhered to the side of the relief portion of the thin die by an adhesive so that the ejection foam protects the relief portion of the thin die and provides a means of ejecting the cut out form of the laminate. Also disclosed is a die and press system using the thin die described herein. A die press is included in the system, which may be a die platen press or a roll die press. The die press includes a cutting tool holder that allows the die to cut through the laminate material and into the cutting tool holder, if a die platen press is used. The system further includes a thin die adapted for use with a matrix press. The thin die includes a base portion, a thin die portion, and an ejection foam portion, wherein the base portion and the ejection foam portion interspersed the thin die portion so that the thin die is located in a indentation located at the base and adhered to the base by means of an adhesive. In addition, the ejection foam portion adheres to the thin die portion to protect the raised portions of the thin die portion. The ejection foam protects the relief portions of the thin die portion and acts as an ejection means to eject the cut shapes from the laminate. Also described herein is a method for making a thin die, wherein the method includes the steps of providing a steel material, chemically attacking a portion of the steel material to leave at least one portion in relief on a surface of the steel material to provide a shape in the steel material. The process further includes adhering the steel material to a base portion so that the raised portion of the steel material is exposed on one side. In addition, an ejection foam adheres to the cutting side of the steel material to protect the relief portions of the steel die and to act as an ejection means to eject the cut shape from a laminate used in a cutting process. BRIEF DESCRIPTION OF THE DRAWINGS The description will now be described in greater detail with reference to the embodiment illustrated in the accompanying drawings, in which like elements bear like reference numerals and where: Figure 1 illustrates a perspective view of a thin die according to the present description; Figure 2 illustrates a cross-sectional view taken of line 2-2 of Figure 1 according to the present disclosure; Figure 3 illustrates a bottom view of the thin die according to the present disclosure; Figure 4 illustrates a system using a platen press or roll and a thin die according to the present disclosure; Figure 5 illustrates the process for manufacturing a thin die according to the present disclosure; and Figure 6 illustrates a top view of the thin die with the ejection foam removed. A thin die is described which is adapted for use in a die press, such as a die platen press or a roll die press. As shown in Figure 1, a thin die is described, such as a chemically etched die assembly 100. The die assembly 100 includes a base portion 102 and a ejection foam portion 104. As will be further described in the following, ejection foam portion 104 has a shape 106 that follows the contour of an embossed portion of the thin die portion of the assembly. Shapes 106 are defined by shape flanges 108. Form flanges 108 define the shapes 106 in the ejection foam 104 and are created during the first use of the chemically attacked die assembly 100, the first use of which can be done at the factory to test the die or can be carried out by the user of the die assembly 100. The ejection foam portion 104 includes an ejection foam flange 110 that follows a flange 112 of the base portion. Figure 2 is a cross-sectional side view taken on line 2-2 of Figure 1. Figure 2 illustrates how the portions are assembled to include the final assembly configuration of the die assembly 100. The base portion 102 includes a base portion indentation 202 to define the base portion peripheral flange 112. Chemically etched die 206 includes a relatively flat portion 207 and an opposing relief portion as defined by 208 and lower portions 210. The flat portion 207 of the chemically etched die 206 adheres to the base indentation 202 so that the chemically etched die 206 is located in and surrounded by the base portion peripheral flange 112. A layer of adhesive 204 adheres to the flat portion 207 of die chemically etched to the base indentation 202. This adhesive 204 can be a foam adhesive, a spray adhesive or any other means for adhering the flat portion 207 of the chemically etched die to the base indentation portion 202. The ejection foam portion 104 adheres to the lower portions 210 of the chemically etched die 206. The ejection foam portion 104 adheres to the lower portions 210 of the chemically etched die 206 by an adhesive 212. The adhesive 212 may be a foam adhesive, spray adhesive, or any other means for adhering the foam portion 104 ejection to the lower portions 210 of the chemically attacked die 206. The close-up view shown in Figure 2A illustrates an exemplary embodiment wherein the ejection foam adhesive 212 is limited to the lower portions 210 of the chemically etched die 206. In this embodiment, this configuration prevents the ejection foam material 104 from bonding or interfering with the relief portion, or the cutting surface 208 of the chemically etched die 206. Alternatively, the adhesive adheres to lower portions 210, as well as portions 208 in relief cut. In this embodiment, when the first use or cutting of the die occurs, the relief portion 208 of the die simply cuts through the adhesive and the ejection foam. The height of the raised or cut portion of the die portion is 0.053 centimeters (.021 inches), with the base of the die portion being 0.025 centimeters (.010 inches), the base of the relief portion or Die cut portion is approximately 0.053 centimeters (.021 inches) wide at the bottom and is approximately 0.010 centimeters (.004 inches) wide at the top, with a flat cutting surface of approximately 0.005 centimeters (.002 inches) wide. Of course, these dimensions are exemplary only and are not intended to limit the claims. For example, the upper portion of the relief cut portion may vary anywhere from 0.025 centimeters (.001 inches) to 0.012 centimeters (.005 inches), for example without crushing the material to be cut. , Figure 3 illustrates the lower part of the chemically etched die assembly 100, wherein only the base portion 102 is seen. The base portion 102 includes a rear side 300. The rear side 300 includes an indentation 302 on the back side. The rear side indentation 302 allows a label 304 with identification indentations 306 to be located in the rear side indentation 302. As shown in Figure 3A, which is a cross-sectional view taken of the line 3A-3A of Figure 3. The depth of the rear side indentation 302 is greater than the height of the label 304 so that the forces transferred through the die assembly 100 are uniform through the die assembly 100 when the die assembly 100 is used with a die press. Is this represented in Figure 3? wherein the depth of the rear side indentation 302 is identified by d and the height of the label 304 is identified by h, where d >; h. As shown in Figure 4, the thin die described herein can be used with a platen die press 402 with a cutting tool holder 404 and an optional adapter 406. Alternatively, the thin die 100 described herein can be used with a roll press 406. The laminated material 408, which may comprise paper, plastic, skin, or a variety of other materials, is placed between the thin die 100 and the cutting tool holder 404. The pressure is applied to the thin die 100 through the platen press 402 so that the raised portion for the cutting portion 208 of the chemically etched die portion 206 is forced into and through the laminated material 408 and toward the cutting tool holders 404 so that the desired shape is cut out of the laminated material 408. Alternatively, the chemically etched die stamps the shape of the relief portion of the die in the laminated material 408. In this embodiment, the embossed portion 208 is not so sharp as not to cut through the laminated material 408 when the die is pressed from the press. If a roller press 406 is used with the thin die 100 described herein, the laminated material 408 and the thin die are fed through the rollers of the roll press 406 so that the pressure is exerted towards the die 100. thin and towards the laminated material 408 so that the desired shape is cut out of the laminated material 408. If a roller press 406 is used, the rollers may include a rubber or other elastic layer so that the embossed portion or cutting portion 208 of chemically etched die 206 is not damaged when it is fed through the rollers of the die. 406 roller press. Also described herein is a method for manufacturing a thin die assembly 100, as described herein. Figure 5 illustrates the method for manufacturing the thin die, which includes the steps of providing a sheet of flat stock material which can be a steel for springs with a high hardness 45 or nominal value HRC. The steel material is cleaned to remove dust and oils from steel surfaces. The steel material is also degreased to remove the grease from the raw material of the steel sheet. The raw material of the steel sheet is then rinsed with water to remove any degreasing material on the steel surfaces. The steel material can then be rinsed with acid to further remove any grease or other particles on the surfaces of the steel material. The steel material is then rinsed with water again to remove any remaining acidic chemicals on the steel surfaces. The steel material is then debugged with a scrubbing roller. The scrubbing roller can be formed from a nylon material. The steel material is then rinsed again and the steel material then dried. The steel material is then dedusted to remove any dust on the steel surfaces. Afterwards, the steel surfaces that are not going to be chemically attacked, are laminated with a dry film. The dry film can be a dry film with a YQ-30SD specification. The dry film is applied to steel surfaces at a temperature of 115 ° C at a pressure of 4.92 kilograms per square centimeter or kg / cm2 (70 pounds per square inch or psi). The laminated film is exposed to form the image and / or the word in a negative on the steel surface, with the negative result being on the steel surface which is exposed with a strong light. This development process is completed at a temperature of 12 ° C and a pressure of -720 miriHg. The laminate is developed by the steps to remove the dry film without exposing the dry film, to get the image and the word located on a surface of the steel material. A development solution includes a chemical known as NaC03 in a 1% solution, at a temperature of 30 ° C, and at a pressure of 1.5 kg / cm2 and with a contact time of 50 seconds of the development solution with the rolled steel material. The steel material is then rinsed with water and blow-dried. Then, the steel material is chemically etched without the dry film with a chemical solution of FeCli3 to get the image and / or the word in the steel material. It is this stage that creates the portions 208 in relief or in section and the portion 210 below. It is the lower portion 210 that is etched to the strong water, while the relief portion or the cut portion 208 remains in the original thickness of the steel material. The etching process includes a chemical known as FeCL3 at 41%, with a specific gravity of 1.41, HCL 31% with a specific gravity of 1,151, and PC-420 with a specific gravity of 1,288. In addition, this is carried out at a temperature of 48 ° C, and a pressure of 3.0 kg \ cm2 and with the steel material being exposed to this chemical solution approximately 22 minutes. Then, the steel material with the resulting chemically etched surfaces is rinsed with water and blow-dried. Then, the dried laminated film is peeled from the embossed or cut portion 208 with a chemical known as 5% NaOH, at a temperature of 48 ° C and at a pressure of 2.0 kg / cm2 and a contact time of 60 seconds. . Then, the steel material with the network form etch is exposed to a chemical etching process again, without any dry laminated film located on the embossed or cut portion 208. This removes any sharp edge of the portion 208 in relief or in section and further defines the portion 208 in relief or in section. This stage is known as a second stage of etching. At this stage, the steel material with the almost network form is exposed to attack chemicals for approximately 20 to 25 seconds; however, this stretch of time is only exemplary and is a function of the thickness of the chemically etched die and the strength and composition of the etching materials. Then, the steel material is rinsed by pressure and blow-dried, and then an antioxidant can be applied to the steel material. The antioxidant must not interfere with the adhesion of the ejection foam on the steel material or the adhesion of the steel material on the base portion 102. Next, the resulting steel material, otherwise known as chemically etched die portion 206, is applied to the base portion 102, and then the ejection foam material 104 is applied to the cut side of chemically etched die 206. The sponge material that is used can be known as PORON, a cellular urethane foam, part number 470130-25025-04, from Rogers Corporation, Oodstock, CT. Alternatively, the sponge material may be of the neoprene family and, more particularly, a synthetic neoprene, such as chloroprene rubber, otherwise known as CR foam. CR foam is a durable and relatively inexpensive foam since it is synthetic. The raw material of the steel sheet that is provided may allow a plurality of chemically etched dies 206 to be etched from a piece of laminated raw material. Therefore, a plurality of chemically etched dies 206 can be machined from the piece of laminated raw material, with the separation of the individual dies from the laminated raw material that is achieved in the etching step. Although this description has been shown and described with respect to detailed embodiments, those skilled in the art will understand that various changes in form and detail may be made without departing from the scope of the present disclosure.
