    专利说明:

    The invention relates to the processing of metals by pressure, in particular to the manufacture of sheet metal roofing material similar to tiles.
    The closest in technical essence and the achieved result to the invention is a method of manufacturing a metal sheet roofing material, in which the sheet is profiled at the first stage to produce a cross section, perpendicular to the surface of the sheet, mostly sinusoidal in shape, at the second stage a transverse form is formed a ledge of a given height by means of at least two dies consisting each of a pair of tools moving towards each other from one another by clamping in them a profiled sheet and moving one punch relative to another perpendicular to the plane of the profiled sheet for a distance corresponding to the height of the step, and then the pre-shaped sheet is successively moved by an amount equal to the distance between the steps and forming the following ledges LI
    The disadvantage of this method is that the distance between the steps is not precisely maintained due to the uncertainty of the process of forming the step.
    The aim of the invention is to improve the quality by ensuring accurate spacing between the steps.
    The goal is achieved by the method of manufacturing a metal sheet roofing material, in which the sheet in the first stage is profiled to produce, in a section perpendicular to the surface of the sheet, a portion of a wavelike, predominantly sinusoidal shape, in the second stage a preformed sheet is formed
    "
    transverse ledge of a given height
    by means of at least two dies each consisting of a pair of tools moving towards each other and from each other by clamping a profiled sheet therein and moving one punch relative to the other perpendicular to the plane of the profiled sheet on
    the distance corresponding to the height of the ledge, and then pre-profiled, the sheet is successively moved by an amount equal to the distance between the ledges, and the following ledges are molded, the pre-shaped sheet is clamped in the second stamp during the feed with the force preventing the sheet from slipping relative to the tool surface when moving one stamp relative to another, and in the first stamp the sheet is clamped with less force, allowing the sheet to slip relative to the tool when the stamp is moved and upon reaching the tension stresses in the sheet, P1) yielded yield strength.
    The clamping force of the sheet in the second stamp is 25-10.0%, mainly by 50%, Bbmie clamping force in the first stamp.
    The molding of the ledges can be carried out by applying additional force to one of the tools of the second stamp and moving this stamp.
    FIG. 1 shows a portion of a pre-shaped sheet. in fig. 2 - section of the profiled sheet with transverse steps; in fig. 3 is a section A-A in FIG. 2; figure 4 is a set of stamps; FIG. 5, section BB, FIG. BUT; FIGS. 6a-6d, the duty cycle for forming a step; in fig. 7 - diagram of the drive stamps.
    FIG. 1 shows a section of a sheet profiled in dies or on a sheet bending machine, as a result of which the sheet has acquired a desired undulating, for example sinusoidal, section. On the sheet 1 thus profiled, the steps 2 described below are perpendicular to the main plane of the sheet transverse to the direction of profiling (see Fig. 2 and 3). I
    For implementing the method, two stamps are provided, each consisting of a pair of tools 3, 4 and 5, 6, respectively. Every1) 1st tool 3-6 can be moved in the direction to the opposite tool and back by forces 7 and 8, respectively, of hydraulic cylinders or other power means. The sheet 1 is fed in the direction of the arrow 9. Each tool has a working surface 10 and 11, configuration
    KOTOpofi corresponds to the profile of a pre-shaped sheet (see Fig. 5). Tools 3, 4 and 5, 6, respectively, in each of the mentioned pairs have surfaces corresponding to the cross-section of the profiled sheet, which ensures their tight fit to each other.
    The distance between the dies should be greater than the thickness of the sheet 1. Preferably it is 2-10 times the thickness of the sheet. According to a known method, molding step 2 is carried out by installing a pre-shaped sheet between two pairs of tools 3, 4 and 5, 6, respectively, and clamping a sheet between them, after which the pairs of tools are moved relative to each other in a direction perpendicular to the plane of sheet 1. However in the known method, uncontrolled sliding movement between the surfaces of the tools 3 and the sheet 1 occurs. This leads to the fact that the distance (see Fig. 2) between two successive ledges 2 is not held and folds are formed in the zones schematically shown by circles C in FIG. 2, and / or cracks in 3qHax, shown schematically in FIG. 2 circles VL
    Thus, the folds tend to form near the inflection point of the wavy profile, and the cracks - at the highest and lowest points of the profile.
    Due to the fact that the height h of the step 2 corresponds to the difference of the heights of the two tiles, which overlap one another in the tile roof, i.e. is a few cm, and the fox has a crowd of only 0.5-1 mm, it is necessary that the sheet slip relative to the surfaces of the tools and not break when forming the ledge. Commercially available sheet metal usually has an elongation at break of a maximum of 15-30%.
    The molding of ledges 2 is carried out as follows.
    After giving the sheet 1 a preliminary wavy profile, for example a sinusoidal one, the sheet is inserted between the tools 3, 4 and 5, 6 in the direction of the arrow 9. In FIG. 6a this position is shown schematically
    Then, force 7, 8 is applied to all the instruments, with the result that the sheet is clamped in the dies.
    However, the clamping force of the sheet in the first pair of tools 3, 4 must be different from the clamping force in the second pair 5.6 so that the clamping force 8 in the second pair 5, 6, i.e. in the second pair in the course of the supply, significantly exceeds the force 7 clamped in the first pair of tools 3, 4.
    After the force 7, 8 is applied, the stamps are moved relative to each other at a distance h, corresponding to the height of the desired step 2 (see Fig. 6s), resulting in a step 2 of tools 5,6 must, in accordance with the preferred option, have a length corresponding to and between two adjacent ledges.
    The clamping force 8 of the sheet in the second pair of tools 5, 6 is set in such a way as to completely prevent sliding movement between the pair of tools 5, 6 and sheet 1, and the force 7 is clamped in the first pair of tools 3, 4 set to such a value that sheet 1 starts sliding relative to the surfaces of this pair of tools, when a certain tensile stress is produced in the sheet as a result of the relative movement of the dies.
    The tensile stress in the sheet on the step should be lower than the tensile strength of the sheet material, but higher than its yield strength. Due to this, when the tensile stress reaches the aforementioned value, the sheet does not break, but begins to slide relative to the first pair of tools 3, 4 and continues to slide as much as is necessary to form a step.
    Due to the creation in the sheet of tensile stress, the value of which is in the range between the yield strength of the sheet and the tensile strength of it for stretching, as well as the sliding of the sheet relative to the tools and its exit into the deformation zone, the sheet will be deformed (stretched) evenly which ledge will have a flat |. | shape and position between the dies. The angle between the flat surface of the step and the direction of movement of the dies depends on the distance between them. By stretching the sheet, which, in addition to the direction parallel to the direction of movement of the dies, also occurs in other directions, i.e. at an angle of about 45 ° to said direction, it prevents the formation of wrinkles and / or cracks. Since the sliding of sheet 1 occurs only with respect to the first pair of tools 3,4, the distance from between two adjacent ledges will always be the same. The result of this is that each element of the roofing material, containing, for example, five tiles in its width direction and five skulls in its longitudinal direction, will be substantially the same as the others. When such elements are bonded to each other, an impenetrable roof is obtained with exactly adjacent elements matching each other along their profile. In addition, the clamping force 8 in the second pair of tools 5, 6, i.e. in the second pggamp in the course of the supply, about 25-100%, and preferably about 50%, higher than force 7 in the first pair of tools 3, 4. Of course, the clamping force 7 in the first stamp must be adjusted in accordance with the above. The combination of sheet material properties, such as yield strength, tensile strength, and sheet friction coefficient relative to the tool, is of crucial importance. The relative movement between the pairs of tools 3, 4 and 5, 6, respectively, in accordance with the invention, is carried out by applying to one of the tools a pair 5,6 (preferably to the upper tool 5) of an additional force corresponding to approximately 5,065 clamping force 8 in the second pair of tools . Typical values of the aforementioned vultures when forming a steel sheet with a thickness of 0.5 mm and a width of 1000 mm with a step height of 112 mm and a distance a between two adjacent steps of 350 mm are as follows. The clamping force in the first pair of tools 3j 4 consists of 5-15 tf, and in the second pair 5.6-20-30 tf. When moving pairs of tools relative to each other, the force acting on the second pair of tools 5, 6 is increased to 40-50 ton-force. After stamping in this way, step 2, tools 3, 4 and 5, 6 are separated from each other, as shown in FIG. 6, and advance the sheet forward by a distance corresponding to the required distance a between two successive steps 2. Thereafter, next ledge. In the preferred embodiment, each tool 3-6 can be moved by hydraulic cylinders 12-15, each of which is a double acting hydraulic cylinder. For each cylinder 12-15, a conduit 16-19 is provided to move the corresponding tool in the direction of the opposite tool and a second pipeline 20-23 to move the corresponding tool in the direction away from the opposite tool. In addition, a valve 2427 is provided for each cylinder 12-15, to which pressure oil is supplied from pump 28 through line 29. A drain system 30 to 33 is normally provided (see Fig. 7). As regards the positions shown in FIG. 6b-6c, then first (see Fig. B), pressure is generated in all cylinders 12-15 through pipes 16-19, and a higher pressure is applied to cylinders 14 and 15 of the second pair of tools 5, 6 than to cylinders 12, 13 of the first pair of tools 3, 4, as a result of which the clamping force in the second pair of tools is greater than in the first pair, Ll ensuring the action shown in FIG. 6c, the cylinders 12, 13 of the first pair of tools 3, 4 maintain a constant pressure, and the pressure in the cylinder 14 of the upper tool 5 of the second pair of tools is increased by operating the corresponding valve 24. At this time, the clamping force will increase, while the second pair tools 5, 6 will move down
    with respect to the first pair 3, 4 to the position shown in FIG. 6c. When the upper cylinder 14 moves the second pair of tools downward, the pipeline 19 connected to the cylinder 15 of the lower tool 6 discharges the oil at a predetermined pressure in the pipeline 19. Then, the po pipelines 20-23 are pressurized to all cylinders 12-15 and the oil is drained through pipelines 16-19 so as to create a distance between the tools that exceeds the height of the step, which will allow the sheet metal in FIG. 6-1 to the right.
    It is obvious that the schematically described hydraulic system can be changed without changing the working sequence of tool movements.
    In addition, cylinder 13 can be omitted. In this case, the lower tool 4 of the first stamp is fixedly fixed. Another modification is the replacement of the cylinder 15 connected to the lower tool 6 of the second die. A spring capable of providing the required amount of clamping force in the second die and moving the second pair of tools 5, 6 relative to the first pair of tools 3, 4.
    In accordance with the present invention, it is possible to process sheets having a non-sinusoidal a. Any other undulating profile, and also to use sheets not of steel but of another material. In some respects, aluminum sheets are preferable to steel sheets.
    As regards wavy profiles, it is possible, for example, to form the curved sections and the adjacent flat sections.
    The above dimensions and efforts should also be considered as examples only, which can be modified depending on the required configuration and sheet material.
