Detailed implementation manners

[0020] Embodiment 1:

[0021] Please refer to Figures 1-8 , a stamping die mold base for a new energy vehicle wheel hub, including a loading mechanism 1, a feeding mechanism 2, and a stamping mechanism 3. The loading mechanism 1 is located at the starting end of the overall mechanism, and the stamping mechanism 3 is located at the end of the overall mechanism. The loading mechanism 1 is used to clamp and transport the to-be-processed plate to the feeding mechanism 2. The feeding mechanism 2 is located at the end of the loading mechanism 1 and is used to transport the to-be-processed plate to the stamping mechanism 3. And the to-be-processed plate does not need to be positioned on the stamping mechanism 3. The stamping mechanism 3 is located at the end of the feeding mechanism 2. The above devices are sequentially installed from the starting end to the end.

[0022] Specifically, the loading mechanism 1 includes a support frame body, a conveyor belt 11, and a material clamping member 12. The conveyor belt 11 is disposed on the support frame body, and the installation height of the conveyor belt 11 is higher than that of the feeding mechanism 2. A plurality of driving wheels 111 are arranged on the inner circumference of the conveyor belt 11. Both sides of the plurality of driving wheels 111 are rotatably connected to the support frame body, and the plurality of driving wheels 111 are matched with the conveyor belt 11 so that when the driving wheels 111 rotate, the conveyor belt 11 is driven to rotate around the outer circumference of the plurality of driving wheels 111. The material clamping member 12 is fixedly arranged around the outer circumference of the conveyor belt 11. There are a plurality of material clamping members 12, and the plurality of material clamping members 12 are equally spaced. A material clamping groove 121 is formed in the middle of the material clamping member 12. The material clamping groove 121 is matched with the to-be-processed plate so that the to-be-processed plate can be placed in the material clamping groove 121 for abutting and limiting. It should be noted here that the material clamping groove 121 limits the to-be-processed plate and moves it in the direction of the feeding mechanism 2 through the conveyor belt 11. When the material clamping groove 121 brings the to-be-processed plate to the edge of the feeding mechanism 2, the to-be-processed plate falls out from the upper end of the material clamping groove 121 and is placed on the feeding mechanism 2.

[0023] Through the above technical solution, when the loading mechanism 1 works, the settings of the conveyor belt 11 and the material clamping member 12 greatly improve the loading rate and ensure the safety of manual loading at the same time.

[0024] Specifically, the feeding mechanism 2 includes a base, a limiting wall 21, a blanking slope 22, a blanking plate 23, a support frame 24, a support spring 25 and an auxiliary wheel 26. The limiting wall 21 is placed at the upper end of the base, and the limiting wall 21 is placed at the edge of the upper end of the base so as to form a material placement area between the limiting walls 21. The blanking slope 22 is located within the material placement area, and the set height of the blanking slope 22 decreases from the end close to the feeding mechanism 1 to the end close to the stamping mechanism 3 to form an inclined slope. The upper end surfaces of the blanking slope 22 and the limiting wall 21 are both placed at the lower end of the conveyor belt 11 so that the clamping member 12 can drop the to-be-processed sheet from the upper end onto the blanking slope 22. One end of the blanking plate 23 is connected to the end of the blanking slope 22, and the blanking plate 23 is movably connected to the blanking slope 22. The other end of the blanking plate 23 abuts against the stamping mechanism 3. A plurality of support plates 231 are further provided on both sides of the blanking plate 23, and the plurality of support plates 231 are fixedly connected to the blanking plate 23. A limiting arc plate 232 is provided on the support plate 231, and the inner arc of the limiting arc plate 232 matches the to-be-processed sheet so that the limiting arc plate 232 positions the sheet when the blanking plate moves. A rotating rod 233 is provided in the middle of the limiting arc plate 232, and the limiting arc plate 232 is rotatably connected to the rotating rod 233. The rotating rod 233 penetrates through the limiting arc plate 232 to the support plate 231, and a return torsion spring is built into the rotating rod 233 so that the to-be-processed sheet can be reset when passing through the limiting arc plate 232. The support frame 24 is located at the lower end of the blanking plate 23, the side end of the support frame 24 is fixedly connected to the base, and the lower end of the support frame 24 supports on the ground. The support spring 25 is placed on the upper end surface of the support frame 24. A plurality of support springs 25 are provided, and one end of the support spring 25 is fixedly connected to the upper end of the support frame 24, and the other end of the support spring 25 is fixedly connected to the lower end surface of the blanking plate 23. When the to-be-processed sheet is placed on the blanking plate 23, the support spring 25 provides a supporting force for the blanking plate 23 to keep the blanking process stable. A plurality of auxiliary grooves are also provided in the middle of the blanking slope 22 and the blanking plate 23. The auxiliary wheels 25 are respectively placed in the plurality of auxiliary grooves, and the auxiliary wheels 25 are capable of self-rotation in the auxiliary grooves. When the to-be-processed sheet is placed on the end surface of the feeding mechanism 2, the feeding is completed by the combined action of gravity and the assistance of the auxiliary wheels 26.

[0025] Through the above technical solution, when the feeding mechanism 1 and the feeding mechanism 2 work, the method of manually positioning and placing the to-be-processed sheets one by one in the past is improved to placing multiple to-be-processed sheets on the feeding mechanism 1 and then automatically docking and positioning them, which greatly improves the processing efficiency and reduces the labor cost. Moreover, the to-be-processed sheets can be freely fed, realizing feeding without external force and reducing unnecessary equipment costs.

[0026] Specifically, the stamping mechanism 3 includes a base, a lower die 31, an upper die 32, an alignment groove 33, an alignment post 34, and a telescopic driving member 35. A lower die cavity is formed in the middle of the lower die 31. Three positioning posts 311 and a telescopic positioning post 312 are arranged on the inner circumference of the lower die cavity, and the lower die cavity is a circular cavity. The telescopic positioning post 312 is disposed at one end close to the blanking plate 23, and the setting position of the telescopic positioning post 312 is aligned with the middle of the blanking plate 23. The other three positioning posts 311 are equidistantly arranged from the telescopic positioning post 312 to enclose the lower die cavity through the four positioning posts. An arc surface is formed at the upper end of the telescopic positioning post 312, and a return spring 312-1 is arranged at the lower end of the telescopic positioning post 312. The return spring 312-1 is disposed at the bottom end of the lower die 31, so that when the to-be-processed sheet enters from the blanking plate 23, it presses against the arc surface position of the telescopic positioning post 312 to press the telescopic positioning post 312. When the end of the to-be-processed sheet completely enters the lower die 31, the telescopic positioning post 312 is not under low pressure, and the return spring 312-1 is reset to place the to-be-processed sheet in the three positioning posts 311 and the telescopic positioning post 312 for fastening and limiting. A plurality of jacking mechanisms 314 are formed at the bottom end of the lower die cavity. The jacking mechanism 314 includes a jacking cavity 314-1, a jacking spring 314-2, and a jacking plate 314-3. The jacking cavity 314-1 is formed at the bottom end of the lower die cavity. A plurality of spring cavities are further formed at the bottom end of the jacking cavity 314-1, and the jacking springs 314-2 are respectively disposed in the plurality of spring cavities. One end of the jacking spring 314-2 is fixedly connected to the bottom of the spring cavity, and the other end of the jacking spring 314-2 is fixedly connected to the bottom end of the jacking plate 314-3. Under normal conditions, the jacking plate 314-3 is disposed at the upper end of the jacking cavity 314-1 through the jacking spring 314-2, and the jacking plate 314-3 matches the jacking cavity 314-1. When the upper die 32 is pressed into the lower die 31, the jacking plate 314-3 is pressed into the jacking cavity 314-1, and the jacking spring 314-2 is compressed into the spring cavity. When the upper die 32 finishes stamping the to-be-processed sheet, the upper die 32 rises, and the jacking spring 314-2 is reset to jack up the processed sheet. An upper die cavity is formed in the middle of the upper die 32. The upper die cavity is arranged to match the lower die cavity, and a plurality of positioning grooves 321 are equidistantly formed on the inner circumference of the upper die cavity. The plurality of positioning grooves 321 correspond to the opening positions of the positioning posts 311 and the telescopic positioning post 312, so that when the upper die 32 is placed in the lower die 31, the positioning posts 311 and the telescopic positioning post 312 enter the positioning grooves 321. The alignment groove 33 is located on the circumferential side of the lower die 31, and the alignment groove 33 is formed on the base. The alignment groove 33 matches the alignment post 34. The alignment post 34 is located on the circumferential side of the upper die 32, and the alignment post 34 is correspondingly arranged with the alignment groove 33, so that when the upper die 32 enters the lower die 31, the alignment post 34 can enter the alignment groove 33 to complete the limit.The telescopic driving members 35 are located on both sides of the stamping mechanism 3. The telescopic driving members 35 include telescopic output ends 351 and telescopic output rods 352. The telescopic output ends 351 are located on one side of the stamping mechanism 3, and the telescopic output ends 351 are connected to the telescopic output rods 352. The telescopic output rods 352 are arranged vertically, and one end of the telescopic output rod 352 away from the telescopic output end 351 is fixedly connected to the upper die 32, so as to drive the telescopic output rod 352 to move in the height direction through the telescopic output end 351 and drive the upper die 31 to move in the height direction. In this embodiment, the telescopic driving member is a hydraulic driving member to provide the ability for the upper die 32 to move in the height direction and stamp the to-be-processed plate.

[0027] Through the above technical solution, when the overall mechanism works, the feeding mechanism realizes the overall transportation of multiple to-be-processed plates through the clamping members, and can sequentially place the to-be-processed plates on the feeding mechanism. At the same time, the feeding mechanism drives the to-be-processed plates for micro-positioning and ensures that they can directly enter the lower die. The positioning posts arranged in the lower die can also perform the main position positioning on the to-be-processed plates, so that when the upper die stamps, the to-be-processed plates are placed at the specified positions. After the processing is completed, multiple flat jacking mechanisms are also arranged at the bottom end of the lower die to jack up the processed plates, which is convenient for taking, greatly improving the processing rate of the middle plates of the wheels and reducing the labor cost and labor risk at the same time.

[0028] Embodiment 2:

[0029] Please refer to Figures 9-10 , a die carrier for a stamping die of a new energy vehicle wheel hub, further includes a touch panel 313. The touch panel 313 is located on the outer peripheral wall of the lower die 31, and the touch panel 313 is placed at the lower end of the blanking plate 23. The touch panel 313 is rotatably connected to the wall of the lower die 31, and a touch spring 313-1 is arranged in the touch panel 313. One end of the touch spring 313-1 is fixedly placed in the wall of the lower die 31, and the other end of the touch spring 313-1 is fixedly connected to the touch panel 313. Under normal conditions, the touch spring 313-1 jacks up the touch panel 313 to keep the touch panel 313 in an inclined state. A pressure sensor 313-2 is arranged at the lower end of the touch spring 313-1. When the touch panel 313 is pressed, the touch panel 313 presses the touch spring 313-1 so that the inner wall surface of the touch panel 313 presses the pressure sensor 313-2. The pressure sensor 313-2 has the ability to send out signals. The pressure sensor 313-2 cooperates with the transmission wheel 111. When the pressure sensor 313-2 sends out signals, the transmission wheel 111 rotates and drives the transmission belt 11 to feed the to-be-processed plates.

[0030] It should be noted here that when the upper die 32 moves towards the lower die 31, the end of the blanking plate 23 is placed at the edge of the lower die 31, so that the edge of the upper die 32 will press against the end of the blanking plate 23. At the same time, the end of the blanking plate 23 will move downward to press against the touch panel 313 to trigger the pressure sensor 313-2 to send a signal. This usage method is that when processing the previous sheet to be processed, the next sheet to be processed is loaded onto the feeding mechanism by the signal sent by the pressure sensor 313-2. When the previous sheet to be processed is completed and taken out, the next sheet to be processed immediately enters the lower die 31 for processing, and the operation is cycled to fully improve the operation rate.
