[0019] Beneficial effects of the present invention:

[0020] 1. The present application provides an automatic shaping machine for power lithium battery caps, in which a longitudinal stamping device cooperates with a loading device to stamp and shape the steel cap of the lithium battery cap. At the same time, the longitudinal moving mechanism also drives the grinding device to move downward, and the grinding device is used to grind and shape the excess part of the outer side of the steel cap of the lithium battery cap after stamping and shaping, thereby ensuring the dimensional accuracy of the steel cap in the lithium battery cap after shaping, and ensuring that the steel cap in the lithium battery cap can be assembled into the outer shell.

[0039] Please continue reading Figure 1-Figure 2 A support plate 4 located on one side of the rotating platform 2 is fixedly installed on the top of the base 1, and a longitudinal moving mechanism toward the side of the rotating platform 2 is movably installed on the support plate 4, and the longitudinal moving mechanism is driven to move longitudinally by a moving block 6 arranged on the base 1, see Figure 1-Figure 2The longitudinal moving mechanism includes a moving block 6, and two limit bars 401 are provided on one side of the support plate 4. The two limit bars 401 are respectively arranged on both sides of the hydraulic cylinder 5, and the two limit bars 401 are movably connected with the moving block 6. The moving block 6 is limited by the limit bars 401, so that the hydraulic cylinder 5 drives the piston shaft to move, which can control the stable longitudinal movement of the moving block 6.

[0040] An L-shaped support plate Ⅰ7 is fixedly installed on one side of the moving block 6 and faces the rotating platform 2. Figure 5-Figure 7 Two reinforcing blocks 8 are fixedly installed on the top of the L-shaped support plate Ⅰ7. The two reinforcing blocks 8 are respectively arranged at both ends of the L-shaped support plate Ⅰ7. The arrangement of the two reinforcing blocks 8 can provide stability of the L-shaped support plate Ⅰ7. One end of the top of the two reinforcing blocks 8 is respectively fixedly connected with a guide shaft 9. A longitudinal linkage device is movably mounted on the two guide shafts 9, and a stamping device is provided on the longitudinal moving device.

[0041] The longitudinal linkage device includes a reinforcing plate 10 movably mounted on two guide shafts 9, a support plate 11 is fixedly connected to the bottom of the reinforcing plate 10, and a stamping device is installed on the side of the support plate 11 away from the reinforcing plate 10. Adjusting screw sleeves 12 are respectively threadedly mounted on both ends of the reinforcing plate 10, and the two adjusting screw sleeves 12 are respectively movably mounted on the two guide shafts 9. The outer side of the top of the adjusting screw sleeve 12 is hexagonal in design so that the adjusting screw sleeve 12 can be rotated by a hexagonal wrench. The bottom end of the adjusting screw sleeve 12 is fixedly connected with an adjusting plate 13, and a tension spring 14 is fixedly connected between the bottom of the adjusting plate 13 and the top of the reinforcing block 8, and the tension spring 14 is movably mounted on the outer side of the guide shaft 9. The hydraulic cylinder 5 drives the piston shaft to push the moving block 6 to drive the L-shaped support plate Ⅰ7 and the reinforcing block 8 to move downward. At the same time, the tension of the tension spring 14 is used to pull the reinforcing plate 10, the adjusting plate 13, the reinforcing plate 10, the support plate 11 and the stamping device as a whole to move downward synchronously. The length of the adjusting plate 13 can be adjusted by rotating the adjusting screw sleeve 12.

[0042] The punching device includes a positioning vertical tube 15 movably mounted on the support plate 11, and a die 16 is fixedly mounted on the bottom end of the positioning vertical tube 15. The outer diameter of the die 16 is the same as the outer diameter of the punch 302. Figure 4 The middle of the die 16 is provided with a through hole connected to the inner cavity of the positioning vertical pipe 15. Please continue to refer to Figure 4-Figure 7 A motor Ⅰ17 for driving the positioning vertical tube 15 to rotate is provided on the support plate 11. After controlling the downward movement of the die 16 and cooperating with the punch 302 to stamp and shape the steel cap of the lithium battery cap, the positioning vertical tube 15 is driven by the motor Ⅰ17 to drive the die 16 to rotate, thereby driving the steel cap of the lithium battery cap and the punch 302 to rotate together, so as to subsequently shape the outer side of the steel cap in the lithium battery cap.

[0043] The top of the positioning vertical tube 15 is fixedly connected with a rotating joint 18, and the top of the rotating joint 18 is connected with an air inlet pipe 19. After the die 16 cooperates with the punch 302 to stamp and shape the steel cap of the lithium battery cap, air is injected and pressurized through one end of the air inlet pipe 19 so that the steel cap of the lithium battery cap and the die 16 can fall off, so that the steel cap of the lithium battery cap can rotate and move on the rotating platform 2 together with the punch 302, which is convenient for subsequent unloading and does not affect the die 16 to stamp and shape the steel cap of the next lithium battery cap.

[0044] See also Figure 2 , Figure 5-Figure 7 A grinding device is provided on the L-shaped support plate Ⅰ7 and is located between the two reinforcement blocks 8. The grinding device includes an L-shaped support plate Ⅱ20 arranged on the top of the L-shaped support plate Ⅰ7. A motor Ⅱ21 is fixedly installed on the top of the L-shaped support plate Ⅱ20. A grinding roller 22 is movably mounted on one side of the L-shaped support plate Ⅱ20. The grinding roller 22 is driven to rotate by the motor Ⅱ21. An adjusting screw 23 is movably mounted in the middle of the side of the L-shaped support plate Ⅱ20. The adjusting screw 23 extends to one side of the moving block 6 away from the end of the L-shaped support plate Ⅱ20, and the adjusting screw 23 is threadedly sleeved with the moving block 6. The outer side of the adjusting screw 23 away from the end of the L-shaped support plate Ⅱ20 is hexagonal in design, so that the adjusting screw 23 can be rotated by a hexagonal wrench, thereby controlling the horizontal movement of the L-shaped support plate Ⅱ20 on the L-shaped support plate Ⅰ7. For lithium battery caps of different sizes, the horizontal spacing value between the outer side of the grinding roller 22 and the outer side of the concave mold 16 is adjusted.

[0045] When the steel cap of the lithium battery cap on the punch 302 is punched and shaped, after the die 16 moves down to contact the steel cap, the hydraulic cylinder 5 drives the piston shaft to push the moving block 6 to continue to move down, so that the tension spring 14 is stretched. The tension of the tension spring 14 provides the pressure of the die 16 for punching and shaping the steel cap of the lithium battery cap. At the same time, the grinding roller 22 moves down, and the part of the steel cap protruding to the outside of the die 16 and the punch 302 is the redundant part. The outer side of the grinding roller 22 contacts the redundant part of the steel cap and rotates under the drive of the motor I 17, and the grinding roller 22 is rotated. The rotation direction of the roller 22 is opposite to the direction in which the steel cap is driven by the die 16 to rotate, so that the excess part of the steel cap is ground, and the outer side of the grinding roller 22 is controlled to fit with the outer side of the die 16 by moving the grinding roller 22 from top to bottom, and the conical surface design at the bottom of the grinding roller 22 is used to shear the more protruding parts of the outer side of the steel cap, and then the grinding roller 22 is used for grinding, so as to achieve the effect of quickly grinding the outer side of the steel cap, which not only ensures the overall dimensional accuracy of the steel cap in the lithium battery cap, but also improves the shaping efficiency.

[0046] The support plate 4 is provided with a through slot 402 at the adjusting screw 23. The through slot 402 does not affect the longitudinal movement of the adjusting screw 23 along with the L-shaped support plate Ⅰ7.

[0047] See also Figure 8A slide groove is provided on the L-shaped support plate Ⅰ7, and the opening of the slide groove does not affect the horizontal movement of the grinding roller 22 along with the L-shaped support plate Ⅱ20.

[0048] Please continue reading Figure 5-Figure 7 , a conductive spring 24 is fixedly installed in the middle of the top of the reinforcing plate 10, and a positioning plate 25 is fixedly connected to the top of the two guide shafts 9. An adjusting screw shaft 26 is threadedly sleeved in the middle of the positioning plate 25, and a moving block 27 is sleeved at the bottom of the adjusting screw shaft 26, and the moving block 27 is frictionally sleeved with the adjusting screw shaft 26, so that the adjusting screw shaft 26 and the moving block 27 tend to be relatively fixed under normal conditions, and when an external force acts on the moving block 27, that is, when the moving block 27 is limited, the adjusting screw shaft 26 can be rotated, and conductive terminals 28 are fixedly installed on both sides of the bottom of the moving block 27, and the two conductive terminals 28 are located directly above the conductive spring 24. When the die 16 cooperates with the punch 302 to stamp and shape the steel cap of the lithium battery cap, the outer side of the steel cap does not protrude to the outer side of the die 16, that is, there is no excess part on the outer side of the steel cap, and the steel cap can be assembled into the top cover. At this time, the grinding The roller 22 does not need to cut the excess part of the steel cap, and grinds and shapes the outer side of the steel cap so that the grinding roller 22 can continue to move down until the two conductive terminals 28 contact the conductive spring 24, so that the circuit where the two conductive terminals 28 are located is energized, so that according to the signal of the two conductive terminals 28 being energized, the hydraulic cylinder 5 is controlled to drive the piston shaft to drive the moving block 6 to move up, thereby completing the steel cap shaping work of the lithium battery cap. Because not all steel caps of lithium battery caps have exactly the same size after stamping and shaping, some steel caps will be larger in size, that is, the outer side of the steel cap will protrude to the outer side of the die 16, and some steel caps will be just or smaller in size, and the outer sides of these steel caps do not protrude to the outer side of the die 16. At this time, there is no need to waste time on grinding, thereby further improving work efficiency, and those with just or smaller sizes can be tested and screened by subsequent testing equipment.
