背景技术Background technique
目前，国内存在的卷板机的种类有两种，按辊筒数不同分为三辊卷板机和四辊卷板机，三辊卷板机的结构简单，也易于实现，所以被广泛应用于小的机械装备加工厂，但是因为其结构简单，卷板精度不高，只能卷制圆柱形圆筒，不可卷制任意角度的锥形筒，而且在卷板过程中容易出现不可控的变形；四辊卷板机结构复杂，传动机构较多，卷制圆筒时运动平稳，改变其相应的传动机构时，可以实现卷制任意角度的锥形筒。At present, there are two types of plate rolling machines in China, which are divided into three-roll plate rolling machines and four-roll plate rolling machines according to the number of rollers. The structure of the three-roll plate rolling machines is simple and easy to implement, so it is widely used It is suitable for small mechanical equipment processing plants, but because of its simple structure, the rolling precision is not high, it can only roll cylindrical cylinders, and cannot roll conical cylinders with any angle, and it is prone to uncontrollable errors during the rolling process. Deformation: The structure of the four-roller plate rolling machine is complex, there are many transmission mechanisms, and the movement is stable when rolling the cylinder. When the corresponding transmission mechanism is changed, it can roll the conical cylinder at any angle.
卷板机的传动机构可以有纯机械传动、纯液压传动、机械-液压传动，纯机械传动结构易于设计，但增加加工成本，整体笨重占且地面积较大；纯液压传动动力大、工作效率高、安全性高，但举升不稳定、能耗大、液压管路复杂、维修困难；机械-液压传动很好的中和了前面两种的传动结构的不足，但当卷板形状要求较高时，设计较为复杂。The transmission mechanism of the plate rolling machine can have pure mechanical transmission, pure hydraulic transmission, mechanical-hydraulic transmission. The pure mechanical transmission structure is easy to design, but it increases the processing cost, the overall bulky occupation and a large area; the pure hydraulic transmission has large power and high work efficiency. High, high safety, but unstable lifting, high energy consumption, complex hydraulic pipeline, difficult maintenance; mechanical-hydraulic transmission well neutralizes the shortcomings of the previous two transmission structures, but when the coil shape requires When it is high, the design is more complicated.
因此，发明一种曲率半径可调的渐进式四辊卷板机，采用机械-液压传动机构的四辊卷板机，降低机器使用环境要求，减少加工成本，易于维修。Therefore, a progressive four-roller plate bending machine with adjustable radius of curvature is invented. The four-roller plate bending machine adopts mechanical-hydraulic transmission mechanism, which reduces the environmental requirements of the machine, reduces processing costs, and is easy to maintain.

具体实施方式Detailed ways
下面结合附图和具体实施方式对本实用新型进行详细说明：Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:
如图1、图2、图3、图4和图5，一种曲率半径可调的渐进式四辊卷板机，由上辊筒传动机构、两个侧辊筒传动机构和下辊筒传动机构组成，上辊筒传动机构和侧辊筒传动机构由纯机械传动机构组成，下辊筒由液压传动机构组成。As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a progressive four-roll plate bending machine with adjustable radius of curvature is composed of an upper roller transmission mechanism, two side roller transmission mechanisms and a lower roller transmission mechanism. Mechanism composition, the upper roller transmission mechanism and the side roller transmission mechanism are composed of pure mechanical transmission mechanism, and the lower roller is composed of hydraulic transmission mechanism.
如图1和图2，一种曲率半径可调的渐进式四辊卷板机，上辊筒1分别由左支撑板12和右支撑板13固定位置，由传动机构传递运动实现纯滚动；前侧辊筒2和后侧辊筒3成角度的安装在上辊筒1下方的两侧，由传动机构传递运动实现斜线上下运动；下辊筒4安装在前侧辊筒2和后侧辊筒3的下方并且与上辊筒1保持同一竖直平面，由传动机构传递运动实现直线上下运动。As shown in Figure 1 and Figure 2, a progressive four-roller plate bending machine with adjustable radius of curvature, the upper roller 1 is fixed by the left support plate 12 and the right support plate 13 respectively, and the movement is transmitted by the transmission mechanism to achieve pure rolling; the front The side roller 2 and the rear roller 3 are installed on both sides below the upper roller 1 at an angle, and the movement is transmitted by the transmission mechanism to realize the oblique upward and downward movement; the lower roller 4 is installed on the front roller 2 and the rear roller The bottom of the cylinder 3 and maintain the same vertical plane with the upper roller 1, and the motion is transmitted by the transmission mechanism to realize the linear up and down motion.
如图3，一种曲率半径可调的渐进式四辊卷板机的上辊筒传动机构，由主电动机7连接多级减速器9，减速增转矩后，再由联轴器10与上辊筒1连接，上辊筒1与下辊筒4夹紧板材，上辊筒1滚动依靠摩擦力带动板材在辊筒间滚动，与其他运动结合完成所需圆筒的卷制。As shown in Figure 3, the upper roller transmission mechanism of a progressive four-roller plate bending machine with adjustable radius of curvature is connected by the main motor 7 to the multi-stage reducer 9. After deceleration and torque increase, the coupling 10 and the upper roller The roller 1 is connected, the upper roller 1 and the lower roller 4 clamp the plate, and the upper roller 1 rolls relying on friction to drive the plate to roll between the rollers, and combines with other movements to complete the rolling of the required cylinder.
如图4，一种曲率半径可调的渐进式四辊卷板机的两个侧辊筒传动机构，前侧辊筒2和后侧辊筒3主要起到卷出一定曲率的圆弧作用，两个辊筒可以独立运动，两个侧辊筒的大小一样、位置对称且具有相同的传动机构，因此只介绍一侧的侧辊筒的传动机构，即前辊筒2的传动机构，其传动机构由副电动机14连接一单级减速器16，减速后由两端同时输出，并且分别用相同的联轴器17连接到下面的传动机构；因为要保证辊筒运动两端的水平平稳性，所以辊筒两端的传动机构相同，故只介绍一边，即左侧边，其由单级减速器16减速通过联轴器17与蜗杆18连接，蜗杆18通过连接在其两端的轴承座19进行位置固定，保证蜗杆只旋转运动，不平移运动，蜗轮20的轮毂与丝杠螺母21通过键固定连接，蜗杆18与蜗轮20啮合进行运动传动，其相对位置由丝杠螺母支座22和蜗轮20上方上固定板23确定，丝杠24上端连接侧辊筒2一端的侧辊筒轴承套25，侧辊筒两端分别安装在左机盖6和右机盖5的导轨槽30中；由此，副电动机14转动通过单级减速器16降速传递给蜗杆18，蜗杆18与蜗轮20啮合将转速进一步降低并且改变运动方向，蜗轮20和丝杆螺母21只做旋转运动，故丝杠24由于丝杆螺母21的转动而斜线运动上下，丝杆24与下辊筒轴承套25固定连接，从而使侧辊筒在图2所示导轨槽30中也做斜线上下运动。As shown in Figure 4, the two side roller transmission mechanisms of a progressive four-roller plate bending machine with adjustable curvature radius, the front side roller 2 and the rear side roller 3 mainly play the role of rolling out a circular arc with a certain curvature. The two rollers can move independently. The two side rollers have the same size, symmetrical positions and the same transmission mechanism. Therefore, only the transmission mechanism of the side roller on one side, that is, the transmission mechanism of the front roller 2, is introduced. The mechanism is connected by an auxiliary motor 14 to a single-stage reducer 16, and after deceleration, both ends are output at the same time, and the same coupling 17 is used to connect to the transmission mechanism below; because the horizontal stability of both ends of the roller movement must be ensured, so The transmission mechanisms at both ends of the roller are the same, so only one side, that is, the left side, is introduced. It is decelerated by a single-stage reducer 16 and connected with a worm 18 through a coupling 17. The position of the worm 18 is fixed by bearing seats 19 connected at both ends of the roller. , to ensure that the worm only rotates and does not move in translation. The hub of the worm wheel 20 and the screw nut 21 are fixedly connected by a key, and the worm 18 and the worm wheel 20 are meshed for motion transmission. The fixed plate 23 determines that the upper end of the leading screw 24 is connected to the side roller bearing sleeve 25 at one end of the side roller 2, and the two ends of the side roller are respectively installed in the guide rail grooves 30 of the left machine cover 6 and the right machine cover 5; thus, the auxiliary The rotation of the motor 14 is transmitted to the worm 18 through the single-stage reducer 16, and the worm 18 meshes with the worm wheel 20 to further reduce the speed and change the direction of motion. The rotation of the nut 21 moves up and down obliquely, and the screw mandrel 24 is fixedly connected with the lower roller bearing sleeve 25, so that the side rollers also move obliquely up and down in the guide rail groove 30 shown in FIG. 2 .
如图5，一种曲率半径可调的渐进式四辊卷板机的下辊筒传动机构，为保证下辊筒4两端等速等高运行，下辊筒4两侧放置相同的传动机构，因为下辊筒4只需配合上辊筒1将板材夹紧，所以只需保证其可上下运动即可，由液压缸支座26将液压缸27固定竖直安装在下辊筒4正下方，液压缸27上方分别与下辊筒4两端的下辊筒轴承套28连接，两个液压缸通过油路控制保证其同步上下运动，从而推动下辊筒4上下运动。As shown in Figure 5, the lower roller transmission mechanism of a progressive four-roller plate bending machine with adjustable radius of curvature, in order to ensure that the two ends of the lower roller 4 run at the same speed and height, the same transmission mechanism is placed on both sides of the lower roller 4 , because the lower roller 4 only needs to cooperate with the upper roller 1 to clamp the plate, so it only needs to ensure that it can move up and down, and the hydraulic cylinder 27 is fixed and vertically installed directly under the lower roller 4 by the hydraulic cylinder support 26, The top of the hydraulic cylinder 27 is respectively connected with the lower roller bearing sleeves 28 at both ends of the lower roller 4, and the two hydraulic cylinders are controlled by the oil circuit to ensure that they move up and down synchronously, thereby pushing the lower roller 4 to move up and down.
