Description

Technical Field

[0001] This utility model relates to the field of spinning machines, and more particularly to a horizontal three-wheel high-power CNC spinning machine. Background Technology

[0002] A spinning machine is a piece of equipment used in metal processing. It is primarily used to spin metal sheets or tubes into rotating parts of various shapes. During operation, the metal blank is first fixed onto a rotating mandrel, which is typically mounted on a spindle and driven by a spindle motor. Simultaneously, one or more spinning wheels apply pressure to the rotating blank along a specific trajectory, causing localized plastic deformation. As the spinning wheels feed, the blank is gradually shaped into a rotating part that matches the shape of the mandrel.

[0003] Spinning machines generate a large amount of heat during the spinning process. If this heat cannot be dissipated in time, it can cause localized overheating of the workpiece, leading to changes in material properties and affecting the workpiece's precision. In severe cases, it can even render the workpiece unusable. Furthermore, high temperatures can damage critical components of the spinning machine, such as the spinning wheel and spindle, shortening the equipment's lifespan, increasing maintenance costs and downtime, and significantly impacting production efficiency.

The spindle motor 3 is fixedly connected to the middle of the side plate 2. The spindle motor 3 rotates when powered on, driving the spindle 27 to rotate. The output end of the spindle motor 3 is fixedly connected to the spindle 27, which is used to rotate the spindle 27. The workpiece to be processed is placed and rotated.

A cooling component is fixedly connected to the top of the base plate 1. The cooling component is used to cool down the workpiece to avoid the heat generated by long-term high-speed operation from affecting the accuracy and service life of the equipment.

[0033] Reference Figures 2-4 The cooling assembly includes an eccentric shaft 12, a cylinder 13, and a water tank 29. The eccentric shaft 12 is fixedly connected to the main shaft 27, allowing the main shaft 27 to rotate and drive the eccentric shaft 12 to rotate. The cylinder 13 and the water tank 29 are both fixedly connected to the top of the base plate 1 to ensure the stability of the piston 14 and the water tank 29. The piston 14 is slidably connected inside the cylinder 13, allowing the piston 14 to slide inside the cylinder 13 and regulate the air pressure inside the cylinder 13. A connecting rod 1 is fixedly connected to the top of the piston 14. 5. The connecting rod 15 is used to slide the piston 14. The top of the connecting rod 15 is fixedly connected to the extrusion plate 16. The extrusion plate 16 slides back and forth under the rotation of the eccentric shaft 12. The outer wall of the connecting rod 15 is fitted with a first spring 17. The first spring 17 is used to push the extrusion plate 16 to reset after the extrusion of the eccentric shaft 12 on the extrusion plate 16 is removed. The bottom of the cylinder 13 is fixedly connected to an electromagnetic one-way valve 18 and a check valve 19. The electromagnetic one-way valve 18 and the check valve 19 control the one-way flow of liquid.

[0034] Reference Figure 3The spinning assembly includes three electric push rods 9, which are fixedly connected to the inner wall of the spinning wheel frame 8. The electric push rods 9 can precisely control the position of the spinning wheel 11, thereby changing the pressure between the spinning wheel 11 and the workpiece. The output end of the electric push rod 9 is fixedly connected to a mounting block 10, which provides the mounting base for the spinning wheel 11. A fixing rod 26 is fixedly connected inside the mounting block 10. The fixing rod 26 is used to support the spinning wheel 11 and ensure the stability of the spinning wheel 11 during operation. The spinning wheel 11 is rotatably connected to the side of the fixing rod 26 away from the mounting block 10. The spinning wheel 11 achieves the spinning effect on the workpiece by rotating on the fixing rod 26. The mounting block 10 is equipped with an installation component, which enables the installation and removal of the fixing rod 26, and further enables the installation and removal of the spinning wheel 11.

[0035] Reference Figure 5 The installation assembly includes two limiting plates 22. The outer walls of the limiting plates 22 are slidably connected to the inside of the installation block 10. The limiting plates 22 are used to limit the locking block 24 and prevent the locking block 24 from sliding excessively out of the installation block 10. The locking block 24 is fixedly connected to one side of the limiting plate 22. The locking block 24 is used to abut against the fixing rod 26 to fix the fixing rod 26. The rope 25 is fixedly connected to the other side of the limiting plate 22. The rope 25 is used to provide elasticity, thereby pushing the limiting plate 22 to slide, and further driving the rope 25 to slide, thereby fixing the fixing rod 26. A second spring 23 is sleeved on the outer wall of the rope 25. The second spring 23 is used to pull and drive the limiting plate 22 to slide, thereby unlocking the fixing rod 26.

[0036] Reference Figures 2-4 Multiple nozzles 28 are fixedly connected to the inner wall of the spinning frame 8. The nozzles 28 are used to spray water onto the spinning area to cool the spinning wheel 11. An inlet pipe 20 is fixedly connected between the electromagnetic one-way valve 18 and the water tank 29, so that water inside the water tank 29 can be transported to the inside of the cylinder 13 through the inlet pipe 20. A drain pipe 21 is fixedly connected between the check valve 19 and the nozzles 28, so that water inside the cylinder 13 can be transported to the nozzles 28 for spraying and cooling through the drain pipe 21.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The eccentric shaft 12 protrudes and abuts against the top of the extrusion plate 16, which facilitates the rotation of the eccentric shaft 12 to drive the extrusion plate 16 to slide up and down. One end of the first spring 17 is fixedly connected to the top of the cylinder 13, and the other end of the first spring 17 is fixedly connected to the bottom of the extrusion plate 16, ensuring that the first spring 17 can effectively transmit the elastic force to the extrusion plate 16 when resetting, thereby driving the extrusion plate 16 to reset.

[0038] Reference Figures 1-3The transverse assembly includes a transverse motor 4 and a guide rod 7. The transverse motor 4 is fixedly connected to the outer wall of the base plate 1 and provides power to the entire transverse assembly. The guide rod 7 is fixedly connected to the inside of the base plate 1 and provides guidance for the movement of the transverse assembly. A lead screw 5 is fixedly connected to the output end of the transverse motor 4. The rotation of the transverse motor 4 drives the lead screw 5 to rotate, causing the connecting block 6 on the outer wall of the lead screw 5 to move along the surface of the lead screw 5. The connecting block 6 is threadedly connected to the outer wall of the lead screw 5, and the connecting block 6 is slidably connected to the outer wall of the guide rod 7. The tops of the two connecting blocks 6 are fixedly connected to the bottom of the spinning frame 8. The connecting blocks 6 are used to drive the spinning frame 8 to move during the movement, thereby realizing the adjustment of the spinning position.

[0039] Reference Figure 5 The locking block 24 passes through the mounting block 10 and abuts against the fixing rod 26. The abutment ensures the stability of the connection between the locking block 24 and the fixing rod 26, and ensures that the rotating wheel 11 will not deviate during operation. A handle is provided between the two ropes 25, which facilitates the pulling of the locking block 24.

[0040] Reference Figure 5 One end of the second spring 23 is fixedly connected to the limiting plate 22, and the other end of the second spring 23 is fixedly connected to the inner wall of the mounting block 10, ensuring that the elastic force of the second spring 23 can be effectively transmitted to the limiting plate 22, thereby pushing the limiting plate 22 to slide, and achieving the effect of fixing the fixing rod 26 by the locking block 24.

[0041] Working principle: When a workpiece needs to be spun, the workpiece is placed on the main shaft 27 and fixed. Then, the transverse motor 4 is energized and started. When the transverse motor 4 is energized, it drives the lead screw 5 to rotate, which in turn drives the connecting block 6 to slide on the lead screw 5. When the connecting block 6 slides, it drives the rotating wheel frame 8 to slide. When the rotating wheel frame 8 slides to the workpiece position on the first spring 17, the electric push rod 9 is energized, which pushes the mounting block 10 to slide, so that the rotating wheel 11 and the workpiece on the main shaft 27 come into contact. After the preparation work is completed, the main shaft motor 3 is energized and started. When the main shaft motor 3 is energized, it drives the main shaft 27 to rotate, which in turn drives the workpiece on it to rotate, and the rotating wheel 11 squeezes the workpiece.

[0042] During the extrusion process, the rotation of the main shaft 27 drives the eccentric shaft 12 to rotate. The rotation of the eccentric shaft 12, through its eccentric motion, extrudes the extrusion plate 16. When the extrusion plate 16 is extruded, it drives the connecting rod 15 to slide while simultaneously extruding the first spring 17. The sliding of the connecting rod 15 drives the piston 14 to slide, reducing the pressure inside the cylinder 13. At this time, the water inside the cylinder 13 is transported to the nozzle 28 through the cooperation of the check valve 19 and the drain pipe 21, and sprayed out through the nozzle 28 to cool the rotating wheel 11. When the external force on the extrusion plate 16 disappears, the first spring 17 will reset, causing the connecting rod 15 to slide upward, further driving the piston 14 to slide. Under the action of the electromagnetic one-way valve 18 and the water inlet pipe 20, the water inside the piston 14 is drawn into the cylinder 13.

[0043] When the rotating wheel 11 wears out after long-term use and needs to be replaced, pulling the two ropes 25 will cause the two limit plates 22 to slide, further compressing the second spring 23 and causing it to disengage from the fixing rod 26. Then, the fixing rod 26 can be removed, achieving the effect of quickly maintaining and replacing the rotating wheel 11.

[0044] 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.
