Description

Cutting machine Object of the invention The invention, as the title of this descriptive document states, is a cutting machine. It is an innovation that, within current techniques, offers advantages previously unknown. Thanks to its design and configuration, the machine allows for cutting all types of non-ferrous materials with high precision and without damaging the material, as it does not generate high temperatures or pressures. It can cut soft materials such as fruits, vegetables, and cellulose. It can be controlled numerically, via computer, to vary the cutting size. Therefore, this invention is circumscribed within the field of manufacturing cutting machines for all types of non-ferrous materials and especially high-precision cutting machines. State of the art In different sectors it is necessary to cut material with great precision and to a very small size, even talking about cutting it to a size of nanometers. Various machines exist for performing these cuts, but due to their operating principle, they are not suitable for all types of materials. The cutting process generates high temperatures and pressures that can damage the material. Furthermore, many existing machines lack the necessary precision for various industries. With the aim of solving the problems detailed, the current invention is presented. The existence of any machine with the same technical characteristics as the invention presented here is unknown. Description of the invention The object of the present invention is the creation of a cutting machine that brings a notable innovation within its field of application in the current state of the art, the characterizing details that make it possible being conveniently included in the final claims that accompany the present description. The high-definition cutting machine allows you to cut different materials to a very small size without unnecessarily damaging the material being cut. To do this, the machine understands • A first cylinder provided with a first piston. • A second cylinder, facing the first cylinder and equipped with a second piston. • A connecting head between the two cylinders, inside which are a fixed cutting tool and a rotating cutting tool, both equipped with a series of through-holes or perforations between the corresponding cylinder and the other cutting tool. In the contact zone of the two cutting tools, the material is broken by shearing. The number of holes, the rotational speed, and their cross-section define the particle size of the cut. • A loading opening for the crushed material in the first cylinder. • An outlet or discharge point for the material cut in the second cylinder. • The first and second pistons are moved by a low pressure (10 bar or less) and high speed hydraulic system (for example, on the order of 50 cycles per minute). Each cutting tool can be in one cylinder or the other, with the rotary cutting tool usually being in the second cylinder, where less pressure accumulates, to make it easier to connect it to the outside to have the rotary motor. To improve machine control, it is preferable to arrange the cylinders horizontally, so that the density of the material to be cut, due to gravity, does not affect the machine's behavior. Explanation of the figures To complete the description being made and in order to help in the better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part thereof, by a figure in which, for illustrative and non-limiting purposes, the following has been represented. Figure 1 shows a view of the machine that is the subject of the invention. Preferred embodiment of the invention The present invention relates to a high-speed, low-pressure cutting machine, which provides a notable innovation within its field of application, the characterizing details that make it possible being conveniently set out in the claims. The low-pressure, high-speed cutting machine shown in the figure comprises a first cylinder (1) in a horizontal position, provided with a first piston (2). It also has a second cylinder (6) in a horizontal position and facing the first cylinder (1) and provided with a second piston (8). It has a connecting head (7) between the cylinders (1, 6), inside which there is a fixed cutting tool (5) and a rotating cutting tool (9), both provided with a series of through-holes (10) between the corresponding cylinder (1, 6) and the other cutting tool (5, 9). The connecting head (7) is made of two separable parts. This machine configuration makes changing the cutting tools (5, 9) very easy, both the fixed cutting tool (5) and the rotating cutting tool (9). Both plungers (2, 8) push the material to be cut against the cutting tools (5, 9), controlling the direction of movement and their retraction. The rotary cutting tool (9) is driven by a motor controlled by a programmable logic controller (PLC). The PLC allows the movement of the rotary cutting tool (9) to be programmed, for example, to rotate in one direction or the other. Depending on the placement of the cutting holes (10) of each cutting tool (5, 9), the overlap between the holes of each cutting tool (5, 9) can be made very small. This is used to cut material into relatively small dimensions. For example, by positioning the cutting holes (10) at different distances from the axis of rotation of the rotary cutting tool (9), so that the overlap of the holes is only partial. It is also possible to replace one or both cutting tools (5, 9) to obtain smaller cutting holes (10). There is a loading opening (3) for the crushed material in the first cylinder (1), and an outlet opening (4) or discharge opening for the cut material in the second cylinder (6). The first cylinder (1) and second cylinder (6) are moved by a third piston, which will generally be a hydraulic piston (11). This hydraulic cylinder (11) pushes the first cylinder (1) and the second cylinder (6) by means of a double-acting hydraulic circuit. In a preferred embodiment, the rotary cutting tool (9) moves from 0 to 6000 rpm, the rotational speed being controlled by the automaton. Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field may understand its scope and the advantages that derive from it, it being noted that, within its essentiality, it may be put into practice in other modes of embodiment that differ in detail from the one indicated as an example, and which will also achieve the protection sought provided that its fundamental principle is not altered, changed or modified.
