Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-5An embodiment of this utility model provides a sheet metal edge rolling device, including a frame 1 and a mold 7. The mold 7 is a detachable module. To cope with sheet metal parts of different sizes, the mold 7 needs to be replaced and adjusted. The bottom of the frame 1 is fixedly connected to a cabinet 10. The inside of the cabinet 10 is fixedly connected to a motor box 19. The top of the motor box 19 is rotatably connected to a rotating shaft 3. A locking component is installed on the outside of the rotating shaft 3. The top of the frame 1 is rotatably connected to a mounting block 9. A clamping component is installed on the top of the mounting block 9.

[0037] The locking assembly includes a latch 13, which is fixedly connected to the outside of the rotating shaft 3. The mold 7 has a T-shaped locking groove 12 inside. Springs 15 are fixedly connected to both sides of the inner wall of the locking groove 12, and locking blocks 14 are fixedly connected to the other end of each spring 15. The locking blocks 14 and the latch 13 engage with each other. When the mold 7 needs to be assembled, the latch 13 fixed on the rotating shaft 3 is inserted into the locking groove 12 of the mold 7. The springs 15 on both sides retract, and the locking blocks 14 move to both sides. After the latch 13 enters, the springs 15 release and pop out, and the locking blocks 14 lock the latch 13. A lever 11 is fixedly connected to the outside of the mold 7. A groove 25 is opened inside the mold 7. The lever 11 is slidably connected inside the groove 25. When the mold 7 needs to be replaced, the lever 11 is moved, the spring 15 is compressed, the locking block 14 moves, and the locking tongue 13 disengages, so the mold 7 can be easily replaced. A second motor 17 is fixedly connected inside the motor box 19. The purpose of the motor box 19 is to support the motor and facilitate subsequent operations. The rotating shaft 3 is fixedly connected to the output end of the second motor 17. When the second motor 17 rotates, the rotating shaft 3 rotates, and the mold 7 rotates, which can make the edge rolling more uniform.

[0038] Reference Figure 1 , Figure 5 and Figure 6 The clamping assembly includes a housing 2, which is fixedly connected to the top of the mounting block 9. An electric push rod 8 is fixedly connected to the outer side of the housing 2. A connecting rod 23 is rotatably connected to the output end of the electric push rod 8. Extending the electric push rod 8 rotates the connecting rod 23. A gear 22 is rotatably connected to the other end of the connecting rod 23. Rotating the connecting rod 23 causes the gear 22 to rotate. A rack 21 is slidably connected inside the housing 2. The rack 21 and the gear 22 mesh with each other. When the gear 22 rotates, the rack 21 moves horizontally. The outer side is fixedly connected to a gripper 4, and the rack 21 moves to control the gripper 4 to hold it. The inside of the cabinet 10 is fixedly connected to a motor 20, and the mounting block 9 is fixedly connected to the output end of the motor 20. The rotation of the motor 20 can drive the mounting block 9 to rotate, and the entire clamping assembly rotates to unload the sheet metal parts, thereby improving production efficiency. The inside of the cabinet 10 is fixedly connected to a hydraulic rod 18, and the motor box 19 is fixedly connected to the output end of the hydraulic rod 18. Driving the hydraulic rod 18 causes the mold 7 and the rotating shaft 3 to descend, thereby demolding the sheet metal parts.

[0039] Reference Figure 1, Figure 5 and Figure 7 The top of the frame 1 is slidably connected to the housing 5 via an electric slide rail. The electric slide rail includes a slide rail to ensure the sliding of the slider, internal ball bearings to reduce friction, motor drive, and controller for precise control. This is existing technology and will not be described in detail. The bottom of the housing 5 is fixedly connected to a slider 16. The top of the frame 1 has a slide groove 26. The slider 16 is slidably connected inside the slide groove 26 to move the housing 5 to a suitable position. The inside of the housing 5 is fixedly connected to a motor 24. The output end of the motor 24 is fixedly connected to a curling wheel 6. The motor 24 is driven to rotate the curling wheel 6 to complete the curling.

[0040] Working principle: First, select a suitable mold 7 and install it on the rotating shaft 3. The rotating shaft 3 has a locking tongue 13. The locking tongue 13 is inserted into the locking groove 12 of the mold 7. The spring 15 in the locking groove 12 is compressed and drives the locking blocks 14 at both ends to move to both sides. After the locking tongue 13 enters, the spring 15 is released and pops out. The locking blocks 14 lock the locking tongue 13, and the mold 7 can be fixed on the rotating shaft 3. If it needs to be replaced, turn the lever 11. The spring 15 is compressed and the locking blocks 14 move to both sides. The locking tongue 13 disengages and can be replaced. The mold replacement is more convenient and faster, reducing the time spent on mold replacement.

[0041] Furthermore, once mold 7 is fixed, a circular sheet metal piece is fitted onto it. The curling wheel 6 is pushed to the appropriate position via an electric slide rail, driving motors 24 and 17. The curling wheel 6 rotates, curling the sheet metal. After completion, an electric push rod 8 is used to push connecting rod 23 and gear 22 to rotate, causing rack 21 to move horizontally. This controls gripper 4 to hold the sheet metal piece, driving hydraulic rod 18 to lower mold 7 and remove the sheet metal piece. The drive motor 20 rotates, and the clamping assembly rotates to place the finished product on the table, completing the automatic unloading function. This improves product production efficiency and is easy to operate.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
