Description

Technical Field

[0001] This utility model relates to the field of metal plastic forming technology, and in particular to a fully automatic end cap spinning forming machine. Background Technology

[0002] In industrial production, end caps are crucial components of various equipment, and their forming accuracy and production efficiency directly impact the overall performance of the equipment. The fully automatic end cap spinning machine, a key piece of equipment for achieving efficient and precise end cap forming, can process blanks into the required end cap shapes through automated spinning, and is widely used in machinery manufacturing, automotive, and home appliance industries.

[0003] Existing end cap spinning forming equipment typically uses a rotating mechanism to drive the blank to rotate, while simultaneously using a spinning tool to apply pressure to the blank for forming. The technical principle is that the rotational motion of the blank and the feeding motion of the spinning tool cause the blank to undergo plastic deformation under pressure, thereby forming the basic outline of the end cap.

[0004] However, in the existing technology, the blank often lacks stable radial constraint during rotation, which can easily lead to radial offset and swaying. This directly results in uneven force on the blank during spinning, which in turn affects the forming accuracy of the end cap and makes it difficult to meet the production requirements of high-quality end caps. Utility Model Content

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.

[0027] Reference Figure 1 - Figure 4 An embodiment of this utility model is provided: an automatic end cap spinning forming machine, including a shell 1, an electric slide rail 2 fixedly connected to the lower side of the inner wall of the shell 1, a moving table 3 slidably connected to the outer wall of the electric slide rail 2, a clamping assembly provided on the inner wall of the shell 1, a motor 6 provided on the upper side of the inner wall of the shell 1, and a spinning wheel 4 fixedly connected to the output end of the motor 6.

[0028] The clamping assembly includes a limiting ring 11, which is fitted around the outside of the blank under the drive of the connecting column 12, directly restricting the radial displacement of the blank. The limiting ring 11 is set on the inner wall of the outer shell 1. A rotating block 16 is fixedly connected to the bottom of the inner wall of the moving table 3. An electric push rod 14 is fixedly connected to the lower side of the inner wall of the moving table 3. A sliding block 13 is fixedly connected to the output end of the electric push rod 14. The sliding block 13 slides under the push of the electric push rod 14 and transmits power to the limiting ring 11 through the connecting column 12. A connecting column 12 is fixedly connected to the upper surface of the sliding block 13. A sliding groove 10 is opened on the upper surface of the moving table 3. A support platform 7 is fixedly connected to the upper surface of the moving table 3. A second motor 9 is set on the inner wall of the support platform 7. A rotating base 8 is fixedly connected to the output end of the second motor 9, which carries the end cover blank and rotates under the drive of the second motor 9, thereby driving the blank to rotate synchronously and providing a rotational power basis for spinning processing. A rotating shaft 18 is fixedly connected to the lower side of the inner wall of the moving table 3. A connecting rod 17 is fixedly connected to the upper surface of the rotating block 16. A pressing assembly is set above the moving table 3.

[0029] Specifically, the electric slide rail 2 drives the moving table 3 to the designated position. After the operator places the billet, the motor 2 9 drives the rotating base 8 and the billet to rotate. The electric push rod 14 pushes the sliding block 13 to slide along the support column 15. The connecting rod 17 rotates around the rotating shaft 18 to assist the sliding. The sliding block 13 drives the limiting ring 11 to slide along the slide groove 10 through the connecting column 12, so that the limiting ring 11 is fitted on the outside of the billet.

[0030] Reference Figure 1 - Figure 5The pressing assembly includes a pressing cover 23, which is positioned above the moving platform 3. A support frame 5 is fixedly connected to one side of the outer wall of the moving platform 3. A support plate 19 is fixedly connected to the lower surface of the support frame 5. A rotating ball 20 is rotatably connected to the inner wall of the support plate 19, allowing the second support plate 21 to make slight angle adjustments relative to the first support plate 19, indirectly driving the pressing cover 23 to adjust its angle and ensuring good contact with the surface of the billet. The second support plate 21 is fixedly connected to the outer wall of the rotating ball 20. A cylinder 22 is fixedly connected to the lower surface of the second support plate 21. A pressing block 24 is fixedly connected to the output end of the cylinder 22. A sliding column 26 is slidably connected to the inner wall of the pressing block 24. A spring 25 is fixedly connected to the outer wall of the sliding column 26, which is compressed when the pressing cover 23 contacts the billet, preventing... Rigid extrusion damages the billet. One end of the sliding column 26 is fixedly connected to the upper surface of the lower pressure cover 23. The sliding column 26 is used to drive the lower pressure cover 23 to slide. One end of the spring 25 is fixedly connected to the lower surface of the lower pressure block 24. The spring 25 is used to drive the sliding column 26 to move. The lower pressure cover 23 is set above the rotating base 8. The rotating base 8 and the lower pressure cover 23 are used to drive the spun object to rotate while fixing it. One end of the connecting rod 17 is rotatably connected to the lower surface of the sliding block 13. The connecting rod 17 is used to drive the sliding block 13 to rotate. One end of the connecting column 12 is fixedly connected to the lower surface of the limiting ring 11. The connecting column 12 is used to drive the limiting ring 11 to move. The outer wall of the connecting column 12 is slidably connected to the inside of the slide groove 10. The inner wall of the sliding block 13 is slidably connected to the outer wall of the support column 15.

[0031] Specifically, cylinder 22 pushes the lower pressure block 24 down, and through sliding column 26 drives the lower pressure cover 23 to approach and contact the upper surface of the billet. Spring 25 is compressed to provide buffer pressure. Rotating ball 20 allows support plate 21 to finely adjust the angle so that the lower pressure cover 23 always fits the billet. During spinning, it rotates synchronously with the billet. After completion, cylinder 22 retracts and drives the lower pressure cover 23 to reset.

[0032] Working principle: When an automatic end cap spinning forming machine is needed, the electric slide rail 2 drives the moving table 3 to slide to the designated position. The operator places the end cap blank on the rotating base 8. The motor 2 9 starts, driving the rotating base 8 and the blank to rotate synchronously. At the same time, the electric push rod 14 pushes the sliding block 13 to slide along the support column 15. When the sliding block 13 moves, the connecting rod 17 rotates around the rotating shaft 18 to assist the sliding block 13 to slide smoothly. The sliding block 13 drives the limiting ring 11 to slide synchronously along the slide groove 10 through the connecting column 12, so that the limiting ring 11 is sleeved on the outside of the blank, limiting the radial displacement of the blank. During this process, the connecting column 12 slides along the slide groove 10 to ensure the stability of the movement trajectory of the limiting ring 11, thereby achieving radial clamping and fixing of the blank.

[0033] In addition, the pressing component is activated, and the cylinder 22 pushes the pressing block 24 down. The pressing block 24 drives the pressing cover 23 to approach the upper surface of the billet through the sliding column 26 until the pressing cover 23 contacts the billet. At this time, the spring 25 is compressed, and the elastic force provides buffer pressure for the pressing cover 23, ensuring that the billet is axially and stably clamped between the rotating base 8 and the pressing cover 23, and is not damaged by rigid extrusion. In addition, the rotating ball 20 allows the second support plate 21 to be finely adjusted relative to the first support plate 19, so that the pressing cover 23 can adjust the angle according to the surface condition of the billet and always maintain good contact with the upper surface of the billet. During the spinning process, the pressing cover 23 rotates synchronously with the billet, and works with the rotating base 8 to achieve stable rotation of the billet. After spinning is completed, the cylinder 22 retracts, driving the pressing cover 23 to rise and reset, releasing the axial clamping of the billet.

[0034] 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.
