Specific Embodiments

[0020] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0021] Please refer to Figure 1 - Figure 7As shown in the figure, a continuous production line for a new energy motor shaft without annealing in the middle includes a base 1. Above the base 1, there is a conveyor belt 2. On the surface of the conveyor belt 2, there is a placement mechanism 3. At the front and rear ends on the left side of the conveyor belt 2, there are respectively a cold forging mechanism 1 5 and a pushing mechanism 1 6. At the front and rear ends on the right side of the conveyor belt 2, there are respectively a cold forging mechanism 2 7 and a pushing mechanism 2 8; The placement mechanism 3 includes a fixed block 301, and the fixed block 301 is arranged on the surface of the conveyor belt 2. On the left side of the fixed block 301, there is a side mounting plate 302. At the upper end of the side mounting plate 302, a threaded rod 303 is rotatably installed. On the circumferential surface of the lower end of the threaded rod 303, there is a gear 304. On the circumferential surface of the upper end of the threaded rod 303, a lifting block 305 is threadedly connected. On the right side of the lifting block 305, there is a lifting placement table 306. Inside the upper end of the lifting placement table 306, there is a motor shaft 4 placed. On the upper surface of the side mounting plate 302, there is a U-shaped fixing plate 307. The upper end of the threaded rod 303 is rotatably installed inside the upper end of the U-shaped fixing plate 307. Inside the front end of the U-shaped fixing plate 307, there is a positioning rod 308. The setting of the U-shaped fixing plate 307 provides an installation space for the threaded rod 303 and the positioning rod 308, so that the threaded rod 303 and the positioning rod 308 are stably installed on the side mounting plate 302. The front end of the lifting block 305 is sleeved on the circumferential surface of the positioning rod 308. The setting of the positioning rod 308 can limit the lifting block 305 while the lifting block 305 can move in the vertical direction on the threaded rod 303 when the threaded rod 303 rotates; The cold forging mechanism 1 5 includes two hollow support platforms 1 501. On the upper ends of the two hollow support platforms 1 501, there are respectively processing platforms 1 502. At the rear ends of the two processing platforms 1 502, there are respectively outer forming grooves 1 503. The setting of the outer forming grooves 1 503 enables the front end of the motor shaft 4 to be inserted into the outer forming grooves 1 503. While limiting the motor shaft 4, it can prevent the motor shaft 4 from shifting during the front and rear pushing, which affects the cold forging effect. Inside the left outer forming groove 1 503, there is a movable push rod 1 504 installed movably. Inside the right outer forming groove 1 503, there is a hollow push rod 507 installed movably. Inside the hollow push rod 507, there is an opening column 508, and the front end of the opening column 508 is connected to the inside of the front end of the right processing platform 1 502. The settings of the movable push rod 1 504 and the hollow push rod 507 can prevent the motor shaft 4 from being affected when the motor shaft 4 enters the processing platform 1 502 for cold forging, and can also push the motor shaft 4 out of the processing platform 1 502 through the movable push rod 1 504 and the hollow push rod 507 after cold forging. The setting of the opening column 508 enables the front end of the motor shaft 4 to contact the opening column 508 under the pushing of the pushing mechanism 1 6, so as to open a hole inside the front end of the motor shaft 4; The pushing mechanism 1 includes a first hydraulic cylinder 601, and there are two first hydraulic cylinders 601, which are respectively arranged directly behind the two first processing tables 502. Push blocks 602 are arranged at the front ends of the two first hydraulic cylinders 601. U-shaped telescopic connecting plates 603 are arranged on the circumferential surfaces of the telescopic ends of the two first hydraulic cylinders 601. The setting of the U-shaped telescopic connecting plates 603 enables the front ends of the U-shaped telescopic connecting plates 603 not to move synchronously back and forth at the beginning when the first hydraulic cylinder 601 expands and contracts back and forth. Instead, they will move horizontally back and forth only after the internal telescoping reaches the limit. The front ends of the two U-shaped telescopic connecting plates 603 are respectively connected to the rear end of the first movable push rod 504 and the rear end of the hollow push rod 507. Tooth plates 604 are arranged on the left side walls of the two push blocks 602, and the height and teeth of the tooth plates 604 are both matched with the gear 304. When the first hydraulic cylinder 601 drives the tooth plate 604 to move horizontally back and forth, the tooth plate 604 can drive the gear 304 and the threaded rod 303 to rotate, and then smoothly drive the lifting block 305 and the lifting placement table 306 to move in the vertical direction; Activity grooves 505 and moving grooves 506 are respectively opened inside the two first processing tables 502, and the lower end in front of the activity groove 505 is communicated with the upper part of the moving groove 506. The first movable push rod 504 and the hollow push rod 507 are respectively arranged inside the two activity grooves 505, and the front ends of the two U-shaped telescopic connecting plates 603 are respectively arranged inside the two moving grooves 506. The settings of the activity groove 505 and the moving groove 506 provide an activity space for the front ends of the first movable push rod 504, the hollow push rod 507 and the U-shaped telescopic connecting plate 603, enabling the first movable push rod 504, the hollow push rod 507 and the U-shaped telescopic connecting plate 603 to move horizontally back and forth smoothly. Embodiment 2

[0022] Please refer to Figure 4 and Figure 6As shown in the figure, the cold forging mechanism II 7 includes a hollow support platform II 701, and there are two hollow support platforms II 701. Processing platforms II 702 are arranged at the upper ends of the two hollow support platforms II 701. An outer forming groove II 703 is formed inside the front end of the left processing platform II 702. The setting of the outer forming groove II 703 enables the rear end of the motor shaft 4 to be inserted into the outer forming groove II 703. While limiting the motor shaft 4, it avoids the deviation of the motor shaft 4 during the forward and backward pushing, which affects the cold forging effect. An active push rod II 704 is movably installed inside the outer forming groove II 703. An annular groove 707 is formed inside the front end of the right processing platform II 702. A hollow annular push rod I 708 is movably installed inside the annular groove 707. The settings of the active push rod II 704 and the hollow annular push rod I 708 can, without affecting the entry of the motor shaft 4 into the processing platform II 702, after the cold forging of the motor shaft 4 is completed, push the rear end of the motor shaft 4 out of the processing platform II 702 through the active push rod II 704 or the hollow annular push rod I 708. A forming extrusion block 709 is arranged at the center of the rear end of the annular groove 707; The pushing mechanism II 8 includes two hydraulic cylinders II 801. The two hydraulic cylinders II 801 are respectively arranged directly in front of the two processing platforms II 702. Push blocks II 802 are arranged at the rear ends of the two hydraulic cylinders II 801. A hollow annular push rod II 803 and a solid cylindrical push rod 804 are arranged at the rear sides of the two push blocks II 802, and the solid cylindrical push rod 804 is arranged inside the hollow annular push rod II 803. Tooth plates II 809 are arranged at the rear ends on the left sides of the two hollow annular push rods II 803, and the height and teeth of the tooth plates II 809 are both matched with the gear 304. The setting of the tooth plate II 809 can drive the gear 304 to rotate through the tooth plate II 809 when the hollow annular push rod II 803 moves back and forth, enabling the lifting and placing platform 306 to move vertically smoothly. Limit platforms 810 are arranged at the rear sides of the two hydraulic cylinders II 801. The two groups of hollow annular push rods II 803 are respectively movably installed inside the upper ends of the two limit platforms 810. Moving grooves III 806 are formed inside the two limit platforms 810. L-shaped connecting plates 805 are movably installed inside the two moving grooves III 806. The setting of the moving grooves III 806 provides a moving space for the L-shaped connecting plates 805, enabling the L-shaped connecting plates 805 to move horizontally back and forth smoothly. The front ends of the two L-shaped connecting plates 805 are fixedly connected to the lower ends of the two push blocks II 802 respectively. Vertical connecting plates 808 are inserted into the rear ends of the two L-shaped connecting plates 805 respectively. The upper ends of the two vertical connecting plates 808 are fixedly connected to the lower ends of the active push rod II 704 and the hollow annular push rod I 708 respectively. Push blocks III 807 are arranged at the middle and rear ends of the two L-shaped connecting plates 805. The two push blocks III 807 are respectively abutted against the rear sides of the lower ends of the two vertical connecting plates 808; It should be noted that the hollow annular push rod II 803 can completely wrap the front end of the motor shaft 4. After the rear end of the hollow annular push rod II 803 abuts against the rear surface of the motor shaft 4, it can drive the motor shaft 4 to move backward, so that the rear side of the motor shaft 4 moves into the inner part of the outer forming groove II 703 and abuts against the front end of the movable push rod II 704. At the same time, the front end push block III 807 abuts against the vertical connecting plate 808. At this time, when the hollow annular push rod II 803 continues to push the motor shaft 4 backward into the processing table II 702, the front end push block III 807 can push the vertical connecting plate 808 and the movable push rod II 704 to move backward.

[0023] An activity groove II 705 is formed inside the left processing table II 702, and a moving groove II 706 is formed inside both processing tables II 702. The lower end of the activity groove II 705 is communicated with the left moving groove II 706, and the lower end of the annular groove 707 is communicated with the right moving groove II 706. The upper ends of the two vertical connecting plates 808 are respectively arranged inside the two moving grooves II 706. The arrangement of the activity groove II 705 and the moving groove II 706 provides an activity space for the movable push rod II 704 and the vertical connecting plate 808, so that the movable push rod II 704 and the vertical connecting plate 808 can move horizontally back and forth smoothly. An outer forming surface I 401 is arranged on the outer surface of the front end of the motor shaft 4, and the outer forming surface I 401 is cold forged by the left end processing table I 502. A deep hole 402 is formed inside the front end of the motor shaft 4, and the deep hole 402 is cold forged by the right end processing table I 502. An outer forming surface II 403 is arranged on the outer surface of the rear end of the motor shaft 4, and the outer forming surface II 403 is cold forged by the left end processing table II 702. A connecting hole 404 is formed inside the rear end of the motor shaft 4, and the connecting hole 404 is cold forged by the forming extrusion block 709 inside the right end processing table II 702. Among them, the centers of the right processing table I 502, the right hydraulic cylinder I 601, the two processing tables II 702 and the two limiting tables 810 are all arranged at the same height, and are lower than the centers of the leftmost processing table I 502 and the hydraulic cylinder I 601. The difference in height is the radius difference between the outer forming surface I 401 of the motor shaft 4 and the blank motor shaft 4 after cold forging of the motor shaft 4 inside the leftmost machining table I 502.

[0024] When the present invention is in use, first place the blank shaft of the motor shaft 4 on the lifting placement table 306. Then, start the conveyor belt 2 to drive the placement mechanism 3 and the blank shaft to move to the middle between the left hollow support table 501 and the left hydraulic cylinder 601. Next, stop the conveyor belt 2 from moving, and start the hydraulic cylinder 601. The hydraulic cylinder 601 drives the push block 602, the U-shaped telescopic connecting plate 603, and the toothed plate 604 to move horizontally forward. When the push block 602 moves forward, it can push the blank shaft in front of it forward, so that when the front end of the blank shaft is pushed into the inner part of the outer forming groove 503, the U-shaped telescopic connecting plate 603 contracts to the extreme. At this time, when the push block 602 continues to move forward, it can drive the entire U-shaped telescopic connecting plate 603 to move forward, and then drive the U-shaped telescopic connecting plate 603 to drive the movable push rod 504 to move forward, so that while the rear end of the movable push rod 504 abuts against the front end of the blank shaft, it does not affect the movement of the blank shaft. At the same time, when the toothed plate 604 moves forward, it will engage with the gear 304, driving the gear 304 and the threaded rod 303 to rotate, so that the lifting block 305 drives the lifting placement table 306 to move vertically downward, thereby avoiding the high height of the lifting placement table 306 from affecting the horizontal forward movement of the push block 602. When the front end of the movable push rod 504 abuts against the inner wall of the processing table 502, the primary cold forging work of the blank shaft is completed, and the outer forming surface 401 is cold forged and extruded. Then, the hydraulic cylinder 601 contracts backward to reset, the lifting placement table 306 moves back up to the initial height, and the movable push rod 504 pushes the blank shaft backward out of the processing table 502 and back onto the lifting placement table 306; Then, start the conveyor belt 2 again to drive the placement mechanism 3 and the blank shaft to move to the middle between the right hollow support table 501 and the right hydraulic cylinder 601. Next, repeat the above operation. At this time, due to the arrangement of the opening column 508 inside the right processing table 502, when the blank shaft enters the inside of this processing table 502 for cold forging, a deep hole 402 can be opened inside the front end of the blank shaft; Next, the conveyor belt 2 moves the placement mechanism 3 and the blank shaft to the middle of the left end processing table two 702 and the left end hydraulic cylinder two 801. Start the hydraulic cylinder two 801. The hydraulic cylinder two 801 drives the push block two 802, the hollow annular push rod two 803 and the L-shaped connecting plate 805 to move horizontally backward, so that the hollow annular push rod two 803 completely wraps the front end of the motor shaft 4. Then, after the rear end of the hollow annular push rod two 803 abuts against the rear surface of the motor shaft 4, it drives the motor shaft 4 to move backward, so that the rear side of the motor shaft 4 moves into the inner forming groove two 703 and abuts against the front end of the movable push rod two 704. At the same time, the front push block three 807 abuts against the vertical connecting plate 808. At this time, when the hollow annular push rod two 803 continues to push the motor shaft 4 backward into the processing table two 702, the front push block three 807 can push the vertical connecting plate 808 and the movable push rod two 704 backward. Through the setting of the movable groove two 705, the outer forming surface two 403 is cold-forged on the outer surface of the rear end of the blank shaft. After that, the hydraulic cylinder two 801 contracts. First, it drives the push block two 802, the hollow annular push rod two 803 and the L-shaped connecting plate 805 to move horizontally backward, so that the hollow annular push rod two 803 is completely removed from the blank shaft. Then, after the rear push block three 807 abuts against the vertical connecting plate 808, it drives the vertical connecting plate 808 and the movable push rod two 704 to move forward, so as to push the blank shaft out of the processing table two 702 and push it onto the lifting placement table 306; Next, the conveyor belt 2 moves the placement mechanism 3 and the blank shaft to the middle of the right end processing table two 702 and the right end hydraulic cylinder two 801, repeats the operation of the hydraulic cylinder two 801 above, and then opens the connecting hole 404 inside the rear end of the blank shaft through the forming extrusion block 709 arranged inside the right end processing table two 702, thus completing the non-annealing continuous production work of the motor shaft 4.
