Description

Technical Field

[0001] The invention relates to the technical field of plate rolling machines, and in particular to a three-roller differential speed variable curvature CNC plate rolling machine. Background Art

[0002] Three-roller plate rolling machines are divided into mechanical and hydraulic types: mechanical three-roller plate rolling machines are divided into symmetrical and asymmetrical types. They can roll metal sheets into round, arc-shaped and conical workpieces within a certain range. The working principle is that the upper roller makes vertical lifting and lowering movements in the central symmetrical position of the two lower rollers, which is obtained through the screw, nut and worm transmission, and the two lower rollers make rotational movements driven by the motor. The output gear of the reducer meshes with the gear of the lower roller to provide torque for the rolled sheet, so that the metal sheet undergoes multiple continuous bends to produce permanent plastic deformation, and is rolled into the required cylinder, cone or part of them. It is widely used in industrial production;

[0003] The existing patent (Announcement No.: CN212551142U) is a horizontal unloading device for a CNC plate rolling machine, including a work plate, the top of the work plate is fixedly connected to a work table, the top of the work table is fixedly connected to a plate rolling bottom arc, the right side of the top of the work plate is fixedly connected to a fixed table, the top of the fixed table is fixedly connected to a first motor, the output end of the first motor is fixedly connected to an output rod, and the surface of the output rod is fixedly connected to a plate rolling roller. The utility model uses a hydraulic cylinder, a material receiving table, a driving frame, an adjustable strong support rod, a movable shaft, a movable wheel, a screw, a second motor, a screw block and a rubber pad to enable the device to achieve a high degree of automation, solving the problem that the unloading device of the plate rolling machine on the existing market does not have a high degree of automation, the unloading is time-consuming and laborious for the staff, and the unloading and transportation of large pipes is inconvenient, which affects the work efficiency and has safety hazards.

[0004] 1. In the above-mentioned comparative patent, automatic unloading of metal workpieces can be achieved by arranging an automatic unloading device above the plate rolling machine. However, the device can only unload cylindrical metal workpieces. When the plate rolling machine is used to process conical or arc-shaped workpieces, it is also impossible to hang the metal workpiece on the fixed frame for automatic unloading. In addition, when the plate rolling machine bends the metal plate, a large amount of metal debris is likely to be generated, which falls on the plate rolling machine and affects the cleanliness of the plate rolling machine. If the metal debris falls inside the parts, it is easy to damage the parts, requiring the user to clean it in time, which increases the labor intensity of the user.

[0033] The driving mechanism 13 includes a threaded rod 131, a motor 132, a moving block 133, a support frame 134, a support frame 2 135, a support frame 3 136, and a connecting plate 137. The inner surface of the bearing 2 9 is fixedly connected with the threaded rod 131, the left outer surface of the threaded rod 131 is fixedly connected with the motor 132, the motor 132 is located on the left side of the left support seat 2, the outer surface of the threaded rod 131 is threadedly connected with the moving block 133 near the right side of the left support seat 2, the front and rear ends of the moving block 133 are fixedly connected to the slider 12, and the moving block 133 is fixedly connected to the slider 12. 3 is fixedly connected with support frame one 134 on both front and rear sides of the right outer surface, and support frame two 135 is fixedly connected with the front and rear sides of the upper end outer surface of the moving block 133 near the support frame one 134, and the right outer surface of the support frame two 135 is fixedly connected with a support frame three 136 near the upper end, and the other end of the support frame three 136 is fixedly connected with the support frame one 134, and the support frames one 134, two support frames 135 and three support frames 136 are designed in a triangular structure, and the lower end outer surface of the moving block 133 is fixedly connected with a connecting plate 137.

[0034] By adopting the above technical solution, after the metal plate processing is completed, the user can control the clamping assembly 14 to clamp and fix the metal workpiece, and then control the motor 132 to rotate forward to drive the threaded rod 131 to rotate. Since the threaded rod 131 is threadedly connected to the moving block 133, the moving block 133 will be driven to move horizontally to the right inside the slide groove 11 through the slider 12, which greatly improves the stability of the movement. The moving block 133 and the clamping assembly 14 are fixedly connected together through the support frame 134. When the moving block 133 moves to the right, it can drive the clamping assembly 14 to clamp the metal workpiece and move to the right. Since the support frame 134, the support frame 2 135 and the support frame 3 136 are designed in a triangular structure, the stability of the clamping assembly 14 is greatly improved, and the load-bearing capacity of the clamping assembly 14 is guaranteed. When the moving block 133 contacts When it reaches the limit block 6, the motor 132 stops rotating. At this time, the clamping assembly 14 clamps the metal workpiece to the top of the receiving platform 19, and the clamping assembly 14 is controlled to loosen and put down the metal workpiece. The motor 132 is controlled to reverse and drive the clamping assembly 14 back to its original position, which can realize automatic unloading of metal workpieces of different shapes and sizes, thereby greatly improving the practicability of the device and improving work efficiency. When the moving block 133 moves to the right, the connecting plate 137 can drive the cleaning assembly 15 to move to the right to clean the metal debris and dust at the bottom of the inner surface of the plate rolling machine body 1 and collect them in the storage box 18, which not only ensures the cleanliness of the plate rolling machine body 1, but also effectively reduces the damage of tiny metal debris to machine parts. No manual cleaning is required, which greatly reduces the labor intensity of the user and has high overall practicability.

[0035] As an embodiment of the present invention, Figure 1 As shown, the length of the support frame 134 is half of the length of the upper roller 7, and the length of the slide groove 11 is equal to the distance between the left support seat 2 and the right support seat 3.

[0036] By adopting the above technical solution, it is ensured that the clamping assembly 14 is exactly in the middle position of the guide rail 10, which can better clamp the metal workpiece, and it is ensured that when the moving block 133 moves to the rightmost position of the slide groove 11, it can drive the clamping assembly 14 to just stop at the upper end of the receiving platform 19, which facilitates the removal of the metal workpiece, realizes automatic unloading, and greatly improves work efficiency.

[0037] As an embodiment of the present invention, Figure 4 As shown, the clamping assembly 14 includes a hydraulic telescopic rod 141, a connecting rod 142, and a fixing clamp 143. The outer surface of the upper end of the support frame 134 is fixedly connected to the hydraulic telescopic rod 141 near the right end. The outer surface of the hydraulic telescopic rod 141 on the side close to the upper roller 7 is hinged with a connecting rod 142. The top of the connecting rod 142 is hinged with a fixing clamp 143. The outer surface of the fixing clamp 143 on the side away from the upper roller 7 is hinged to the hydraulic telescopic rod 141 near the middle position.

[0038] By adopting the above technical solution, the user can control the extension of the hydraulic telescopic rod 141, use the top of the connecting rod 142 as a fulcrum, drive the fixing clamp 143 to clamp the metal workpiece in the middle, and play a supporting role at the same time. The clamping assembly 14 is driven by the moving block 133 to stably move the metal workpiece to the upper end of the receiving platform 19. After retracting the hydraulic telescopic rod 141, the fixing clamp 143 can be controlled to release the metal workpiece and place it on the receiving platform 19 for the user to pick up.

[0039] As an embodiment of the present invention, Figure 4 As shown, the fixing clamp 143 is designed as an arc-shaped structure, and it matches the metal workpiece. A rubber gasket is fixedly connected to the outer surface of the fixing clamp 143 on the side close to the upper roller 7, and the hydraulic telescopic rod 141 is fixed at an inclined angle.

[0040] By adopting the above technical solution, the fixing clamp 143 can be in closer contact with the metal workpiece. By providing a rubber gasket, the friction between the metal workpiece and the fixing clamp 143 is increased, ensuring that the clamping assembly 14 will not fall off easily during the process of moving the metal workpiece, thereby greatly improving the stability of the clamping.

[0041] As an embodiment of the present invention, Figure 2As shown, the cleaning assembly 15 includes a plastic plate 151, a movable groove 152, a magnet block 153, a pressure spring 154, and a cleaning brush 155. The lower end outer surface of the connecting plate 137 is fixedly connected to the plastic plate 151, and a movable groove 152 is opened inside the plastic plate 151. The inner surface of the movable groove 152 is slidably connected to the magnet block 153. The left outer surface of the magnet block 153 is fixedly connected to the pressure spring 154, and the other end of the pressure spring 154 is fixedly connected to the left side of the inner surface of the plastic plate 151. The cleaning brush 155 is fixedly connected to the middle position of the lower end outer surface of the plastic plate 151.

[0042] By adopting the above technical solution, a large amount of metal debris will be generated during the plate rolling machine processing, and will fall to the bottom of the inner surface of the plate rolling machine body 1. The cleaning component 15 is driven to move to the right by the moving block 133. During the movement, the magnetic magnet block 153 can absorb a large amount of metal debris at the bottom of the inner surface of the plate rolling machine body 1 to the lower outer surface of the plastic plate 151 through the plastic plate 151, and the lower end of the plastic plate 151 is fixedly connected with a cleaning brush 155, which can also clean the dust on the bottom during the movement, and at the same time make the metal debris collection On the right side of the cleaning brush 155, when the magnet block 153 contacts the stopper 16, the stopper 16 continues to move to the right and squeezes the magnet block 153 to the left, causing it to move to the left inside the movable groove 152. When the magnet block 153 completely enters the movable groove 152, the magnet block 153 is located on the left side of the cleaning brush 155, while the metal debris is still on the right side of the cleaning brush 155. At this time, there is no magnet block 153 to provide magnetic force directly above the metal debris, so it will automatically fall into the storage box 18 at the lower end, ensuring the overall cleanliness of the plate rolling machine body 1.

[0043] As an embodiment of the present invention, Figure 6 As shown, the magnet block 153 and the movable groove 152 are both T-shaped structures, and the two are matched with each other and slidably connected. There are two pressure springs 154, and the two pressure springs 154 are symmetrically arranged between the left side of the inner surface of the plastic plate 151 and the magnet block 153.

[0044] By adopting the above technical solution, the connection between the magnet block 153 and the movable groove 152 is made tighter, ensuring that the two will not separate from each other during the movement of the magnet block 153 inside the movable groove 152, thereby greatly improving the stability of the movement. After the magnet block 153 loses the resistance force of the block 16, it can stably return to its original state under the action of the elastic force of the two pressure springs 154.

[0045] Working principle: After the plate rolling machine has processed the metal plate, the metal plate will be transformed into a cylindrical, arc-shaped or conical structure. The user can control the extension of the hydraulic telescopic rod 141, and use the top of the connecting rod 142 as a fulcrum to drive the fixing clamp 143 to clamp in the middle, clamp the metal workpiece, and play a supporting role at the same time. The rubber gasket and the arc-shaped structure design make the connection between the metal workpiece and the fixing clamp 143 tighter, increase the friction between the metal workpiece and the fixing clamp 143, and ensure that the clamping component 14 will not fall off easily during the process of moving the metal workpiece, thereby greatly improving the stability of the clamping. After the fixing clamp 143 clamps the metal workpiece, the user can control the motor 132 to rotate forward to drive the threaded rod 131 to rotate. The rod 131 is threadedly connected to the moving block 133, which will drive the moving block 133 to move horizontally to the right inside the slide groove 11 through the slider 12, greatly improving the stability of the movement. The moving block 133 is fixedly connected to the hydraulic telescopic rod 141 through the support frame 134. When the moving block 133 moves to the right, it can drive the clamping assembly 14 to clamp the metal workpiece and move to the right. Since the support frame 134, the support frame 2 135 and the support frame 3 136 are designed in a triangular structure, the stability of the clamping assembly 14 is greatly improved, and the load-bearing capacity of the clamping assembly 14 is guaranteed. When the moving block 133 contacts the limit block 6, the motor 132 stops rotating. At this time, the clamping assembly 14 clamps the metal workpiece to the top of the receiving table 19, and the hydraulic telescopic rod 14 is retracted. 1, put down the metal workpiece, control the motor 132 to reverse, drive the clamping assembly 14 back to the original position, can realize the clamping and automatic unloading of metal workpieces of different shapes and sizes, greatly improve the practicality of the device, improve the work efficiency, and when the moving block 133 moves to the right, it can drive the connecting plate 137 to move to the right, thereby driving the cleaning assembly 15 to move to the right. During the plate rolling machine processing, a large amount of metal debris will be generated and fall to the bottom of the inner surface of the plate rolling machine body 1, then the magnetic magnet block 153 can absorb a large amount of metal debris on the lower outer surface of the plastic plate 151 through the plastic plate 151, and the lower end of the plastic plate 151 is fixedly connected with a cleaning brush 155, and the dust on the bottom surface can be cleaned during the movement. At the same time, the metal debris is concentrated on the right side of the cleaning brush 155. When the magnet block 153 contacts the stopper 16, the stopper 16 continues to press the magnet block 153 to the left, causing it to move to the left inside the movable groove 152. When the magnet block 153 completely enters the movable groove 152, the magnet block 153 is at the left side of the cleaning brush 155, and the metal debris is still at the right side of the cleaning brush 155. At this time, there is no magnet block 153 to provide magnetic force directly above the metal debris, so it will automatically fall into the storage box 18 at the lower end. The storage box 18 can collect the metal debris, which is beneficial to the recycling of the metal debris. When the cleaning component 15 moves to the left, under the action of the pressure spring 154, the magnet block 153 can return to its original position and continue to work.It not only ensures the cleanliness of the plate rolling machine body 1, but also effectively reduces the damage of tiny metal debris to machine parts. It does not require manual cleaning, greatly reduces the labor intensity of the user, and has high overall practicality.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
