Источники информации, гфин тые во внимаггае при экспертизе 1.Авторское свидетельство СССР №84921, кл. В 21 D 11/20, 1949. The device for flexible edges consists of two C-shaped stand 1 and 2, mounted on base 3 with the possibility of mutual movement one relative to the other along the rails 4 to set the distance 1t, corresponding to the width of the sheet 5. Stamps 1 are installed on the bases 1 and 2 . The working surfaces of tools 6-9 are involuted to the circumference of the circles. The lower tools 6 and 8 are open on the plates 10 and 11 with the possibility of horizontal movement along them by means of, for example, screw pairs 12 and 13. The plates 10 and il are rigidly connected to the power cylinders 14 and .15f are installed on the beds 1; d 2. By means of power cylinders 14 and 15, the lower tools 6 and 8 are moved together with the plates 10 and 11 in the vertical direction, while the upper tools 7 and 9 are nyushfno Zany with beds 1 and 2. The angle of rotation of the upper in trumentov 7 and 9 fixed elements 16. Instru 1en1Y 6-9 can be vsholne br, 1 as valkyuv (see FIG. 7). The rotary axis of the upper 17 instruments may be as. in the center of the rolls, and outside it. The device works as follows, obrz zom. Beds 1 and 2. Installed at a distance equal to the width of sheet 5. Since the working surfaces of the instruments are made with a continuous transition from Γ to rj in accordance with the involute of a circle, tools 6–9 must be installed with a corresponding clearance 8. Tools 6 and 8 move in horizontal direction on the plates 10 and 11; for tool 6, the direction of movement is indicated by the arrow A. Upper tools 7 and 9 are turning; at the angle c ,, for tool 7, the direction of rotation is indicated by the arrow B (see Fig. 2). As a result, a backlash is formed, which is constant over the entire formation zone. If the axis of rotation will be in the center of the tool 6, then for some thicknesses it will be sufficient only in. gate 1 tools 6 and 7. Sheet 5 is fed into a stamp, where its edges are bent. To measure the radius, bending is sufficient to move one machine relative to another. The invention of the device for bending sheet edges, containing two coaxially installed beds, bearing dies, the working surfaces of the upper and lower tools of which have the form of an involute in cross section, and the lower tools are mounted on plates with the possibility of vertical movement by means of power cylinders located on the beds, This is the reason why, in order to increase productivity, the lower tools are installed with the possibility of horizontal movement relative to the plates, and hnie HHCTpjivieHTbi pivotally associated with supports.
