Definitions
- the present invention relates to a cutting device that we will call deformable floating, applicable to any pressure cutting process in which the linear cutting pressure is less than 10 7 N / m and the tolerance in the cutting direction is greater than 0.2 mm, which means that with this device you can cut, among other things, sandwich panels of different compositions.
- these may contain layers of fabric, polyurethane foams, fiberglass, paper, etc., with different thicknesses.
- An example of a typical sandwich used for roof trim manufacturing technologies is the one composed of the following layers: paper, fiberglass, adhesive, polyurethane foam, plastic film and fabric.
- the cutting device is especially suitable for use in the automobile industry, specifically in the manufacture of vehicle roof trim, where simultaneously the roof is formed the cut of the excess material thereof, in the same machine and with the same maneuver.
- the object of the invention is to be able to absorb possible imbalances, wear, or deficiencies of molds and work machines, that is, absorb possible deviations of molds, blades and presses within certain limits. This is due to the fact that in any machine of the aforementioned type there is no tolerance of "0", and in order to achieve a proper cut it is necessary to achieve a perfect fit of the elements involved, for which it is necessary that at least one of They are able to adapt to fit each other's geometry and position.
- the pressure cut is characterized in that the piece is comprised between the knife and the surface until the pressure exerted by both reaches sufficient value to cut the piece.
- said cut knife and sufridera approach progressively until in the final moment in which the cut becomes effective come to direct contact between them.
- Impact cutting could be considered as a variant of pressure cutting in terms of the configuration of the mold and cutting elements. However, in it the speed with which the moving part of the mold moves during the cutting operation is much greater so that the cutting effort is made only by the blade, so that the die simply supports the piece in the cutting area.
- the cutting device of the invention is applicable to pressure cutting systems, which in many cases of cutting and forming of trim is preferable to the other two systems because of its greater simplicity of performance and flability.
- the pressure cutting in order to be effective, requires a very precise adjustment between the rail and the knife, which limits its use and forces frequent and specialized maintenance and adjustment operations.
- the cutting device of the invention is applicable to pressure cutting systems
- the cutting device that the invention proposes focuses its characteristics on the fact that one of the two basic elements that participate in it, whether it is the sufridera, admits certain relative movements of adaptation apart from the cutting movement itself. This implies an adaptation of the mobile part to the fixed part that allows a perfect coupling between both at the end of each cutting cycle, as well as a self-adaptation over time during the life of the cutting tooling, and between different machines.
- the cutting device in addition to being floating, admits some ability to deform elastically.
- the undercarriage is a flexible plate and mounted on an elastic support, such that the pressure of the blade deforms the undercarriage to adapt it to the profile of the blade, while the elastic support must have a constant of rigidity high enough to absorb and distribute evenly the cutting effort at all points of the edge.
- the steel frame must have a sufficient thickness to prevent it from being damaged by the blade, and at the same time also sufficient to be able to adapt by elastic deformation to the latter through its own deformation.
- the elastic support located under the undercarriage must be rigid enough to allow a similar thrust at all points of its surface and at the same time prevent the undercarriage from entering its breast.
- the wheel will preferably be made of alloy steel for wear-resistant tools of the F-500 group (according to Spanish IHA standardization), with surface hardness between 40 and 60 HRc, or in any case of a material with similar mechanical properties.
- the sufridera may be formed by a single sheet being its thickness between 0.5 and 5 millimeters, by two or three superimposed sheets of thickness between 0.5 and 5 millimeters each.
- the runner covers the entire cutting line and consists of consecutive sections of at least 200 mm each, and whose width will be between 4 and 50 mm.
- the elastic or elastomeric support will be of thickness between 2 and 8 millimeters and with hardness between 75 and 95 Shore A.
- thermal insulator with thickness between
- the union between the pavement and the elastomer or elastic support is free by simple support, being the movement of these guided by the pocket that houses them and restricted in the direction parallel to that of cut by a tie that keeps both elements within said pocket as a catch.
- Figure 1 Shows a schematic representation in side elevation of a floating and deformable cutting device made in accordance with the object of the present invention, in which the blade appears independent of the die.
- Figure 2. It shows a representation similar to that of the previous figure, in a working situation, that is to say with the blade pressed against the undercarriage and both this and the deformed elastic support, so that the undercarriage and blade appear perfectly coupled.
- Figure 3. It shows a detail in section of an example of practical embodiment for the mooring of the runner to the mold.
- Figure 4.- Shows, according to a representation similar to that of the previous figure, a variant embodiment for said mooring.
- Figure 5. Shows a schematic representation of the cutting device incorporated into the parts (male and female) that make up a mold of. forming and cutting trim.
- the steel runner (3) rests on an elastic support (4), preferably an elastomer, which deforms simultaneously with the runner (3), absorbing the deformations thereof, as shown in Figure 2.
- the lathe (3) basically laminar, must have a sufficient thickness to prevent it from being damaged by the blade (1), however allowing a perfect adaptation to the latter when both are subjected to the cutting effort.
- the thickness of the undercarriage is small, it will be cut by the blade, while if the thickness of the undercarriage is large, the desired deformation will not be achieved and therefore lights between blade and undercarriage will be produced, determining a defective cut.
- the elastomer (4) must be rigid enough to allow a similar thrust at all points and at the same time prevent the sufferer from penetrating into it.
- a soft elastomer would cause the sufridera to sink into its breast causing the shearing of the same, while a very hard elastomer, still getting the deformation to adapt the blade and suffridera would have some pressure differences that would make the cut also defective in some points and increase the risk of wear or premature damage of the blade.
- the sufridera must have restricted its movement inside its housing to avoid being dragged by the blade in its withdrawal.
- FIG. 3 a first practical embodiment example for the mooring of the runner (3) to the tool of the mold (5), specifically in a pocket (6) of the latter, is shown, example wherein said pocket (6) is of considerably greater width than the runner (3), so that after implantation into said pocket (6) of the elastomer (4) and where appropriate the insulating material (7) , the fixation is carried out with the collaboration of a wedge (8) snap-in in the space of the pocket (6) that leaves the runner (3) free.
- the runner (3) can be the same width as the pocket
- the mission of the insulator (7) which is optional, is to prevent the transmission of heat from the mold to the die, when the working temperatures are high enough to degrade the elastomer material.
- the device allows using the same tooling on different machines without the need for prior adjustments.
- the pieces obtained can be directly assembled according to only the molding machine, avoiding subsequent touch-up operations.
- Breakdowns of the cut can be solved in the work machine itself. - The quality of the cut looks remarkably enhanced, ensuring that such a cut occurs under a wider range of circumstances.
