"DUELA DE LA BLACK WITH SEVERAL SAUSAGES IN THE BED OF THE SAME"
BACKGROUND OF THE INVENTION In the construction industry the stave and the board, made of black sheet, for the manufacture of doors and gates, have predominated for several years. These two products have been marketed for approximately 30 years and have been characterized as not very expensive products. Its low cost is due to the material of which they are made, the steel sheet or black sheet. The black sheet is a sheet of SAE 1010 steel (0.1% carbon evenly distributed through its crystalline atomic network), and its commercial name is obtained due to its surface finish. The hardness, one of the characteristic properties of this material, is obtained thanks to the carbon that is added during the manufacturing processes prior to the lamination. The direction of rolling or rolling, directs the granular structure of the material longitudinally creating internal tensions that give it greater strength and rigidity. The large number of applications and uses of this material make it very commercial, and this is why it is much cheaper compared to aluminum, wood and cast iron, materials that are also used for the same purpose. Previous to the stave and the board, the smooth black sheet was used as the lining of the doors and gates, that is, without any bending, taking advantage of its already mentioned characteristics: hard, rigid and cheap. The disadvantage presented was the great flexibility due to the thickness of the sheet (± 0.76 - ± 1.21mm), which reduced its rigidity considerably. To give it the rigidity required and counteract that flexibility, it began to make certain folds, and that is where the board comes from followed several years after the stave. (The board is manufactured in 20 gauge sheet (± 0.9 mm thick) and in a 22 gauge sheet (± 0.76mm thick), this consists of a section of smooth sheet with veins 1.9cm wide and high, and separated from each other every 15cm, which is assembled by overlapping the eyebrow at one end of the one piece, with the vein, also from one end, from another piece The plank is a profile of 20 gauge sheet that is manufactured in roller or rolling machines, its figure, seen transversally, is a "U" or channel with bed and two eyebrows, one simple and one double, which serve to take two pieces, the single eyebrow of one of them is assembled or fitted in the double eyebrow of the other.The stave comes in different sizes of bed (wide): 2cm, 4cm, 6cm, 8cm and 10cm The stave also has the disadvantage of not be able to exceed a certain bed width by falling back into the aforementioned flexibility. The long life in the market both of the stave and the board, has made them very seen and outdated products, which has caused the population to search, without success, some other material that is novel and that is within reach. in price. Given the need to find an innovative, inexpensive and very good looking product that would replace the traditional board and the already very much seen, the design of a new product similar to the stave arose but with a certain number of sausages in the same bed. that give it greater rigidity and a resemblance (already painted and assembled) to a wooden gate with carved frames. This gate would resemble wood, but with the difference of not needing continuous care or a high investment for its purchase. It is a new product of black sheet manufactured within the technological sphere of the metalworking industry by which several products of different designs and assemblies are obtained, which serve to give housing construction in general a combined touch of elegance, safety, easy handling and low cost. The invention consists of obtaining from the black sheet a much wider stave than the conventional one but with the necessary rigidity that it obtains thanks to the prints on its bed, all this so that it is assembled practically and easily with other existing profiles on the market and together form a board, lining or view for gates. This product comes to give the general public a new option to beautify the facades of their homes, businesses, shops, buildings, etc.
All this causes that a new panorama opens up in the construction industry in regard to doors and gates, preventing the public from resorting to other materials that are of a very high cost, and that in many occasions they can not pay. The granular structure that presents the black blade presents us with a series of difficulties in regard to sausages due to their internal tensions. This is verified taking into account that the deepest part of a sausage is tied to the part farthest from it, and therefore, the deformation that may suffer the sheet that is part of the sausage directly affects the one that is not part of he. Physically we can observe this when analyzing a classic sausage process, where the edges of the material are affected when wrinkled and therefore undulate. This has been counteracted with the use of a foil clamp or fastener that, like the punch, is attached to a movable plate called a punch holder. The clamp is attached to this plate by means of screws but separated from it by springs that contain in the middle the same clamping screws and that serve to contract when the punch performs its work of stuffing. The force exerted by this tramp is given by the type and quantity of springs that it needs depending on the work to be done and the material to be used. The main function of the crusher is to prevent the edge sheet from crumpling, creating unwanted corrugations or reliefs, but allowing the foil to flow into the sausage cavity. This has solved the problem of the undulations and has been sufficient to satisfy the needs that this task implies, but the lack of uniformity of the edges as far as the diameter is concerned, causes that the edges have to be cut 90% of the Sometimes a job like this is done, because only the material that is inlaid is useful. The difficulty, which involved finding the way to manufacture the innovative product lies basically in the aforementioned regarding the sausage process. A product was designed that would be manufactured in black sheet with their respective sausages and their assembly eyebrows, not an easy task since it would be necessary that the sausages were already made, the edges of the sheet were sufficiently uniform (in width) and flat (excellent). of wrinkles or reliefs) both to be able to bend his eyebrows of assembly and not be uneven, as to give the required flatness for being a product that would be used as a gate and that would be in view of the public.
Detailed Description of the Invention Figure 1 is a perspective view of the invention and where its main parts are clearly shown. The invention is a 22-gauge black sheet (± 0.76mm thick) with a single eyebrow (No. 1) that is assembled with another piece through its double eyebrow (No. 2). It is characterized because in the center of the bed (No. 3) has a semi-deep symmetrical sausage (No. 4), which depending on the model varies in shape. Figure 2 clearly shows the shapes of the sausages: rectangular (No. 1), square (No. 2) and circular (No. 3). Thanks to these sausages it can be achieved that the width of the pieces is much greater than the width of the conventional stave, since they give it the rigidity necessary to be part of a strong and safe gate. Since the new parts are much wider than the existing ones, a lot of assembly time is saved, since a certain surface be covered more quickly with the use of the new stave than with the use of the existing one, in addition less welding and hand be used. of work for the assembly. Another feature of the new stave is that it is made of 22-gauge black sheet, whose thickness is ± 0.76mm, ± 0.15mm thinner than the 20-gauge sheet, with which the conventional stave is manufactured, therefore the product besides having the above mentioned advantages, its price is minimized even more because its weight is less than that of the conventional stave. Although the sheet is a little thinner, the rigidity obtained with the sausages does not decrease at all, this is because when embossing the necessary figures, in addition to the existing stresses acquired during the rolling process, it acquires a greater number of these during The process of embossing to be plastically deformed both longitudinally and transversally. The industrial process for the manufacture of a black sheet of stave with several sausages in the bed of the same is made up of the three processes of punching: cutting, bending and stuffing. The first step is to cut the black sheet to the necessary measurements (width and length). This is done with the help of a shear, mechanical or hydraulic, which easily cuts the sections of sheet. Once the sheet is cut to size, it is passed to a hydraulic press, where the die that will shape the sausages is located. Figure 3 is a cross section of the die. This figure shows us clearly the modifications that were made to achieve the prints required by the new product, and the sequence that it follows to make the sausages. -The modifications that characterize this die are: 1. The replacement of both the punch and the matrix, used in conventional dies, by a set of rules (No. 1), a male (No. 1 a, which makes the sometimes of punch) and a female (No. Ib, which acts as a matrix). This pair of rules are responsible for stuffing the sheet (No. 2) to give the desired shape to the sausage. 2. The replacement of the springs that were between the punch holder (No. 3) and the clamp (No. 4), by small hydraulic pistons (No. 5). With the introduction of these pistons it was possible to print enough force to hold the sheet, preventing the edges from shrinking or diminishing in dimension. This brought with it a necessary modification to the punch holder, to which the internal channels (No. 6) were machined by where the hydraulic oil would pass and then stored in the pistons. To drive the oil into the punch holder, a hose (No. 7) was fitted and connected to it at its end. -The steps that are followed in the die are as follows: The first [Letter (a)] is to center the sheet, allowing it to rest on the surface (No. 8) where the presser makes pressure to hold it. Once the foil is centered, the punch holder slowly lowered until the gripper holds it [Letter (b)]. With the blade pressed down enough, the punch holder continues to lower until the top or male ruler shapes the sheet [Letter (c)]. Once the maximum sausage point has been reached, the punch holder returns to its starting point [Letter (d)] from where it leaves again to embed the following figure, repeating this as many times as necessary depending on the number of sausages that the sheet needs. After this, the sheet with the sausages is passed to a bending machine or curtain press where the assembly eyebrows are bent at each end. Once the folding has been completed, the finished product is ready to be assembled with others of the same type.
