    Description BE2020 / 5018 Implementation Plan The present invention is described in detail below with reference to the drawings and specific embodiments: As shown in Figures 1, 2, 3, 4 and 5, a progressive four-roll rolling machine with adjustable radius of curvature is provided by an upper roll transfer mechanism, two side roll transfer mechanisms and a lower roller driven. The mechanism consists of an upper roller transmission mechanism and a side roller transmission mechanism composed of purely mechanical transmission mechanisms, and a lower roller transmission mechanism composed of a hydraulic transmission mechanism.
    As shown in Figures 1 and 2, a progressive four-roll rolling machine with adjustable radius of curvature, the upper roll 1 is fixed by the left support plate 12 and the right support plate 13, respectively, and the transmission mechanism realizes a pure rolling; 153 The side rollers 2 and the rear rollers 3 are installed at an angle on both sides below the upper rollers 1 and are transmitted through the transmission mechanism to realize diagonal movements up and down movements, the lower rollers 4 are on the side rollers 2 and the lower part of the rear roller 3 and the same vertical plane as the upper roller 1 are transmitted through a transmission mechanism to realize linear up and down movements.

    Description BE2020 / 5018
    Front roller 2 and the counter roller 3 mainly play the role of an arc of a circle with a certain curvature.
    The two rollers can move independently of each other.
    The two side rollers are the same size, symmetrical in position and have the same transfer mechanism so that only one side is inserted.
    The 3 transmission mechanism of the side roller, i.e. the transmission mechanism of the front roller 2, whose transmission mechanism is connected by the auxiliary motor 14 to a single-stage reduction gear 16, and after braking it is output at both ends at the same time and is connected to the same clutch 17 respectively to the following Transmission mechanism; since the horizontal stability of the two ends of the roller must be ensured, the transmission mechanism at the two ends of the roller is the same, so only one side, the left side, is introduced, which is braked by the single-stage reduction gear 16 via the clutch 17 connected to the screw 18.
    The screw 18 is fixed by bearing seats 19 which are connected at both ends to ensure that the screw only rotates and does not move.
    The hub of the worm wheel 20 and the screw nut 21 are firmly connected by wedges.
    The worm 18 and the worm wheel 20 mesh with one another. For the transmission of motion, the relative position is determined by the nut holder 22 and the upper mounting plate 23 above the worm wheel 20.
    The upper end of the screw 24 is connected to the side roller bearing sleeve 25 at one end of the side roller 2.
    The two ends of the side roller are respectively mounted on guide slots 30 of the left cover 6 and a right cover 5; Therefore, the rotation of the auxiliary motor 14 is transmitted to the worm 18 via a single reduction gear 16.
    The worm 18 meshes with the worm wheel 20 to further reduce the speed and change the direction of movement.
    The worm wheel 20 and the screw nut 21 only perform rotary movements.
    Therefore, the screw 24 moves up and down due to the rotation of the screw nut 21, and the screw 24 is firmly connected to the lower roller bearing sleeve 25, so that the side roller is in Figure 2, the guide groove shown also moves diagonally up and down.
    As shown in Figure 5, the lower roller gear mechanism is a 30 progressive four roll platen machine with adjustable radius of curvature to ensure the lower roll 4 is driven both ends at the same speed and height; The same transmission mechanism is arranged on both sides of the lower roller 4, since the lower roller 4 is only connected to the upper roller |!
    Description BE2020 / 5018 must work together to clamp the plate in place, just making sure it can move up and down.
    The hydraulic cylinder carrier 26 fixes the hydraulic cylinder 27 vertically and directly under the lower roller 4. The upper part of the hydraulic cylinder 27 is connected to the lower roller bearing sleeves 28 at both ends of the lower roller 4.
    The two hydraulic cylinders ensure that they are synchronized by the up and down movement of the oil circuit, whereby the lower roller 4 is moved up and down.
