DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] The arc steel plate cold rolling device of the utility model is as follows Figures 1 to 5 As shown, it includes a support 1, one end of the support 1 is provided with a feed conveying mechanism, a plurality of forming mechanisms are provided on the support 1, each forming mechanism includes an upper forming roller 2 and a lower forming roller 3, both ends of the upper forming roller 2 and the lower forming roller 3 are rotatably mounted on the support 1, an arc-shaped forming convex surface 4 is provided on the circumferential surface of the upper forming roller 2, an arc-shaped forming concave surface 5 is provided on the circumferential surface of the lower forming roller 3, and a transmission gap is provided between the forming convex surface 4 and the forming concave surface 5; in the transmission direction of the feed conveying mechanism, the curvature of the forming convex surface 4 and the forming concave surface 5 of the forming mechanism gradually increases, and the axial length of the upper forming roller 2 and the lower forming roller 3 gradually decreases.
[0023] The support 1 adopts a metal base in a long strip shape and can be fixed on the ground with anchor bolts, etc., to support other components. The feed conveying mechanism is used to convey the raw material sheet to the forming mechanism. Specifically, the feed conveying mechanism includes an upper transmission roller 22 and a lower transmission roller 23. The upper transmission roller 22 and the lower transmission roller 23 are both horizontally arranged metal rollers, and both ends of the upper transmission roller 22 and the lower transmission roller 23 are installed on the support 1 through bearings. There is a transmission gap between the upper transmission roller 22 and the lower transmission roller 23, and the upper transmission roller 22 or the lower transmission roller 23 is connected to a transmission motor 24. The size of the transmission gap is determined according to the thickness of the raw material sheet to ensure that the raw material sheet can enter the transmission gap, and the upper transmission roller 22 and the lower transmission roller 23 can press the raw material sheet. When the transmission motor 24 drives the upper transmission roller 22 or the lower transmission roller 23 to rotate, the upper transmission roller 22 or the lower transmission roller 23 can pull the raw material sheet to move horizontally.
[0024] The forming mechanism is used to roll the flat plate into an arc-shaped plate with a circular arc section. The forming convex surface 4 of the upper forming roller 2 and the forming concave surface 5 of the lower forming roller 3 are arc-shaped surfaces that cooperate with each other. When the plate passes through the transmission gap between the forming convex surface 4 and the forming concave surface 5, the forming convex surface 4 and the forming concave surface 5 roll the steel plate into an arc, and the curvature of the steel plate is consistent with the curvature of the forming convex surface 4 and the forming concave surface 5. By setting multiple forming mechanisms, and the curvature of the forming convex surface 4 and the forming concave surface 5 of each forming mechanism gradually increases, the steel plate can be gradually rolled. Through multiple rolling, the bending curvature of the steel plate gradually increases, and the deformation of the steel plate is relatively small during each forming, ensuring the forming accuracy. As the steel plate gradually bends, the width of the steel plate will gradually decrease, so the axial length of the upper forming roller 2 and the lower forming roller 3 will gradually decrease to adapt to the change in the width of the steel plate. The width of the steel plate refers to the straight-line distance between the two sides of the steel plate. The curvature and size of the forming convex surface 4 and the forming concave surface 5 of the last forming mechanism are the same as the curvature and size of the required curved steel plate. After the steel plate passes through the last forming mechanism, it becomes a curved steel plate with the required size. A cutting mechanism can be set at the last forming mechanism to cut the rolled curved steel plate into the required length.
[0025] In order to ensure that the steel plate can move in a straight line, the utility model is provided with a guide mechanism between two adjacent forming mechanisms, and the guide mechanism includes a vertical left guide wheel 6 and a vertical right guide wheel 7, and both the left guide wheel 6 and the right guide wheel 7 are rotatably mounted on the support 1. The spacing between the left guide wheel 6 and the right guide wheel 7 is adapted to the width of the steel plate, and the two side edges of the steel plate can contact the circumferential surface of the left guide wheel 6 and the right guide wheel 7, so that the left guide wheel 6 and the right guide wheel 7 limit the steel plate to prevent the steel plate from deviating left and right, and ensure that the steel plate moves in a straight line, thereby ensuring the forming accuracy of the steel plate. In the transmission direction of the steel plate, the spacing between the left guide wheel 6 and the right guide wheel 7 should be gradually reduced to adapt to the width change of the steel plate during the rolling process.
[0026] In order to improve the limiting effect, the side walls of the left guide wheel 6 and the right guide wheel 7 are provided with limiting grooves 8 , which are in a circular shape and the side edges of the steel plates are located in the limiting grooves 8 .
[0027] In order to facilitate the adjustment of the spacing between the left guide wheel 6 and the right guide wheel 7, a horizontal slide rail 9 and a horizontal screw 10 are provided on the support 1. The length direction of the slide rail 9 and the screw 10 is perpendicular to the transmission direction of the steel plate. The two ends of the slide rail 9 are fixed on the support 1, and the two ends of the screw 10 are rotatably installed on the support 1. The slide rail 9 is provided with a left mounting seat 11 and a right mounting seat 12 that slide with the slide rail 9. The screw 10 is provided with a positive thread section and a negative thread section. The positive thread section is provided with a positive thread, and the negative thread section is provided with a negative thread. The positive thread is a conventional thread, and the reverse thread is opposite to the positive thread. The positive thread section passes through the left mounting seat 11 and is threadedly matched with the left mounting seat 11. The reverse thread section passes through the right mounting seat 12 and is threadedly matched with the right mounting seat 12. When the screw 10 is rotated, the left guide wheel 6 is installed on the left mounting seat 11, and the right guide wheel 7 is installed on the right mounting seat 12. The left mounting seat 11 and the right mounting seat 12 can move toward or in opposite directions at the same time, and the movement distance is the same, so as to adjust the distance between the left guide wheel 6 and the right guide wheel 7. When there is no need to adjust the distance between the left guide wheel 6 and the right guide wheel 7, in order to keep the screw rod 10 fixed, the two ends of the screw rod 10 can be loosely matched with the support 1, and fastening nuts are set at the two ends of the screw rod 10, and the screw rod 10 is locked by the fastening nuts.
[0028] In order to facilitate the installation of the upper forming roller 2 and the lower forming roller 3, an upper positioning shaft 13 is fixedly provided at the center of the upper forming roller 2, and a lower positioning shaft 14 is fixedly provided at the center of the lower forming roller 3. In order to facilitate the adjustment of the distance between the forming convex surface 4 and the forming concave surface 5, so as to facilitate the rolling of steel plates of different thicknesses, lifting blocks 15 are fixedly provided at both ends of the upper positioning shaft 13, and the lifting blocks 15 are connected to the support 1 through a lifting mechanism, and fixed blocks 16 are fixedly provided at both ends of the lower positioning shaft 14, and the fixed blocks 16 are fixedly connected to the support 1. The lifting mechanism can drive the lifting blocks 15 to rise and fall, thereby driving the upper positioning shaft 13 and the upper forming roller 2 to move upward or downward, while the height of the lower forming roller 3 remains unchanged, thereby changing the distance between the upper forming roller 2 and the lower forming roller 3.
[0029] The support 1 is provided with a bracket 17, which is a door-shaped bracket, and the lower end of which is fixed to the support 1 by bolts. The fixing block 16 is fixedly arranged at the bottom of the bracket 17, the lifting block 15 is arranged inside the bracket 17, and the lifting mechanism is arranged at the top of the bracket 17.
[0030] In order to improve the stability of the movement of the lifting block 15, the lifting block 15 and the bracket 17 slide in the vertical direction. The lifting mechanism can use a cylinder, a linear motor and other equipment. In order to reduce the cost of the equipment, the lifting mechanism includes a vertical lifting screw 18. The lower end of the lifting screw 18 is fixedly connected to the lifting block 15. The upper end of the lifting screw 18 passes through the top of the bracket 17 and is in clearance with the bracket 17. A locking nut 19 is provided on the lifting screw 18 above the bracket 17. When adjusting, the locking nut 19 is turned, and the locking nut 19 drives the lifting screw 18 to move upward or downward, thereby driving the lifting block 15 to rise and fall. The spacing between the upper transmission roller 22 or the lower transmission roller 23 can also be adjusted in this way.
[0031] The width of the steel plate at the feeding conveying mechanism is the largest, so the upper forming roller 2 and the lower forming roller 3 close to the feeding conveying mechanism are the longest and the weight is also relatively large. In order to reduce the weight of the upper forming roller 2 and the lower forming roller 3, the upper forming roller 2 close to the feeding conveying mechanism includes two upper forming discs 20, there is a spacing between the two upper forming discs 20, and the forming convex surface 4 is arranged on the circumferential surface of the two upper forming discs 20; the lower forming roller 3 closest to the feeding conveying mechanism includes two lower forming discs 21, there is a spacing between the two lower forming discs 21, and the forming concave surface 5 is arranged on the circumferential surface of the two lower forming discs 21. The two upper forming discs 20 and the two lower forming discs 21 cooperate with each other to first roll the two sides of the steel plate, and then the steel plate is rolled again by the integrated upper forming roller 2 and the lower forming roller 3, which does not affect the rolling effect and reduces the weight of the upper forming roller 2 and the lower forming roller 3 close to the feeding conveying mechanism.
[0032] The lower forming roller 3 is connected to a driving motor 25, which can drive the lower forming roller 3 to rotate. When the lower forming roller 3 rotates, it can drive the steel plate to move, providing power for the movement of the steel plate. The feeding conveying mechanism and the rotation speeds of each lower forming roller 3 are adapted to each other, so that the steel plate moves stably and at a uniform speed.
[0033] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
