Technical Field

Since the stamped parts need to be stamped multiple times, when the stamped parts are continuously transferred to the corresponding positions of the next adjacent lower mold, there may be a problem of accumulated errors in the left and right positions of the stamped parts, which leads to a reduction in the stamping accuracy of the stamped parts; 2. When the stamped parts are placed on the next adjacent lower mold, there may be a problem that the stamped parts cannot be accurately fitted on the lower mold, which leads to a reduction in the stamping quality of the stamped parts; 3.

[0032] The present invention is used to convey automobile stamping parts, and the present invention can adjust the left and right positions of the stamping parts when conveying the stamping parts, thereby preventing the accumulation of left and right position errors of the stamping parts when continuously conveying the stamping parts, thereby ensuring the processing accuracy of the stamping parts. At the same time, the present invention can also adjust the front and rear positions of the stamping parts, thereby ensuring that the stamping parts can be accurately fitted on the lower mold 12, thereby ensuring the processing quality of the stamping parts.

[0033] Specifically, first, the stamping part is intermittently transferred to the lower die 12 on the left side by an external conveying device, and the external stamping device is controlled to drive the upper die to stamp the stamping part on the lower die 12, and then the positioning device 4 is controlled to clamp the stamping part, and the conveying device 2 is controlled to drive the positioning device 4 to move upward through the positioning device 3, so that the positioning device 4 lifts the clamped stamping part upward, and the positioning device 4 can adjust the left and right positions of the stamping part, and then the conveying device 2 is controlled to drive the positioning device 4 and the stamping part to move rightward to the adjacent lower die through the positioning device 3. 12 corresponding position, and then control the conveying device 2 to finally drive the stamping part to move downward to the lower die 12 corresponding to the position at this time. At the same time, the positioning device 3 can adjust the front and rear positions of the stamping part through the positioning device 4, so that the stamping part can be accurately fitted on its corresponding lower die. Finally, the positioning device 4 is controlled to release the stamping part, and the conveying device 2 is controlled to drive the positioning device 4 to move to the left to the initial position through the positioning device 3. At the same time, the external stamping device is controlled again to drive the upper die to stamp the stamping part on the lower die 12, and the above steps are repeated to realize the transmission of the stamping part.

[0034] See also Figure 1-Figure 3 Two guide grooves symmetrically arranged front and back are provided at the upper end of the base 1. The conveying device 2 includes a synchronous plate 21 slidably installed in the guide groove front and back. Conveying seats 22 with upper ends set as telescopic structures are slidably installed left and right on the opposite sides of the upper ends of the two synchronous plates 21. An active unit 23 for driving the telescopic end of the conveying seat 22 to move along a circular trajectory is connected between the conveying seat 22 and the synchronous plate 21; a synchronous unit 24 is commonly installed between the two synchronous plates 21 and the base 1, and the synchronous unit 24 includes a No. 1 synchronous screw 241, which is connected to the two synchronous plates 21 by threaded fitting, and the No. 1 synchronous screw 241 is rotatably connected to the base 1, and the rear end of the No. 1 synchronous screw 241 is fixedly connected to the output shaft of the No. 1 motor 242 fixedly installed in the base 1.

[0035] The conveying device 2 is used to convey the stamping parts, and the synchronization unit 24 is used to synchronously adjust the position of the two synchronization plates 21; specifically, after the stamping processing of the stamping parts on the lower mold 12 is completed, the No. 1 motor 242 is controlled to drive the two synchronization plates 21 to move in the direction of approaching each other through the No. 1 synchronization screw 241, so that the two synchronization plates 21 drive the front and rear arranged positioning devices 4 to move in the direction of approaching each other. After the positioning device 4 clamps the stamping parts, the active unit 23 is controlled to drive the conveying seat 22 to move along the circular trajectory, so that the conveying seat 22 first drives the positioning device 4 to lift the stamping parts upward, and then drives the positioning device 4 and the stamping parts to move to the right to the corresponding position of the adjacent lower mold 12, and then the conveying seat 22 drives the positioning device 4 and the stamping parts to move downward to the corresponding position of the lower mold 12 at this time, and controls the positioning device 4 to release the stamping parts. Finally, the conveying seat 22 drives the positioning device 4 to return to the initial position to the left, and at the same time controls the external stamping device again to drive the upper mold to perform stamping processing on the stamping parts on the lower mold 12, and repeats the above steps to realize the conveying of the stamping parts.

[0036] See also Figure 3 and Figure 4 A square hole is provided on the telescopic end of the conveying seat 22, which runs through the left and right ends thereof. The front and rear inner walls of the square hole are provided with an inclined groove 27 with the left end tilted downward.

The lower ends of the two connecting plates 233 are fixedly installed on the synchronous plate 21.

[0037] See also Figure 2 , Figure 4 and Figure 5 A back plate 25 is fixedly installed on the opposite sides of the upper ends of the two synchronous plates 21, and a return groove 28 is opened in the middle of the lower ends of the opposite sides of the two back plates 25. A guide rod 26 is fixedly installed on the side of the telescopic end of the conveying seat 22 close to the back plate 25, and the guide rod 26 is slidably installed in the return groove 28; the upper end of the left vertical section and the lower end of the right vertical section of the return groove 28 are both slidably installed with a limit plate 282 through a tightening spring 281, and the lower end of the left limit plate 282 and the upper end of the right limit plate 282 are both set to an inclined surface.

[0038] The active unit 23 is used to drive the telescopic end of the conveying seat 22 to move along the circular trajectory; specifically, initially, the guide rod 26 is located at the left limit position of the lower side lateral section of the circular groove 28, and the active block 231 is located at the upper limit position of the inclined groove 27. First, the No. 3 motor 234 is controlled to drive the active block 231 to move to the left through the threaded rod 232. At this time, the active block 231 and the inclined groove 27 cooperate to drive the telescopic end of the conveying seat 22 to move upward along the left vertical section of the circular groove 28 under the action of the guide rod 26. At the same time, the guide rod 26 can cooperate with the inclined surface of the left limit plate 282 and compress the clamping spring 281, so that the guide rod 26 moves to the upper limit position of the left vertical section of the circular groove 28, and the limit plate 282 can limit the lower end of the guide rod 26 under the action of the clamping spring 281.

[0039] Then, the third motor 234 is controlled to drive the active block 231 to move to the right through the threaded rod 232. At this time, the limit plate 282 limits the lower end of the guide rod 26, so that the active block 231 drives the conveying seat 22 to move to the right along the upper horizontal section of the circular groove 28 to the right limit position under the action of the guide rod 26, and continues to control the third motor 234 to drive the active block 231 to move to the right through the threaded rod 232. At this time, the active block 231 and the inclined groove 27 cooperate to drive the telescopic end of the conveying seat 22 to move downward along the right vertical section of the circular groove 28 under the action of the guide rod 26. At the same time, the guide rod 26 can cooperate with the inclined surface of the right limit plate 282 and compress the clamping spring 281, so that the guide rod 26 moves to the lower limit position of the right vertical section of the circular groove 28, and the limit plate 282 can limit the upper end of the guide rod 26 under the action of the clamping spring 281.

[0040] Finally, the third motor 234 is controlled to drive the active block 231 to move to the left through the threaded rod 232, so that the active block 231 drives the conveying seat 22 to move to the left along the lower horizontal section of the circular groove 28 to the left limit position under the action of the guide rod 26, and then the conveying seat 22 returns to the initial position, and the above operation is repeated to make the telescopic end of the conveying seat 22 move along the circular trajectory.

[0041] See also Figure 1 , Figure 2 and Figure 6 The alignment device 3 includes a fixed plate 31 fixedly mounted on the upper end of the conveying seat 22, a toggle unit 32 is mounted on the fixed plate 31, a plurality of alignment plates 33 evenly arranged left and right are mounted on the toggle unit 32, and the toggle unit 32 is used to toggle the alignment plates 33 back and forth.

[0042] The alignment device 3 is used to adjust the front and rear positions of the stamping parts; specifically, when the conveying seat 22 moves downward along the vertical section on the right side of the circular groove 28, the conveying seat 22 drives the fixed plate 31 to move, and the fixed plate 31 drives the positioning device 4 and the stamping parts clamped therein to move downward through the toggle unit 32 and the alignment plate 33. At the same time, the toggle unit 32 drives the stamping parts to move forward and backward through the positioning device 4, so that the stamping parts can be accurately fitted on their corresponding lower molds 12, thereby ensuring the stamping processing quality of the stamping parts.

[0043] See also Figure 3 and Figure 6 The toggle unit 32 includes a toggle plate 321 slidably mounted on one side of the fixed plate 31 close to the middle of the base 1, a top extension spring 322 is connected between the toggle plate 321 and the fixed plate 31, and the toggle plate 321 is slidably connected to its corresponding alignment plate 33 through a connecting spring 323 on one side of the base 1; a matching rod 324 is fixedly mounted on the right end of the toggle plate 321, and the right end of the matching rod 324 slides back and forth through the right end of the fixed plate 31, a vertical plate 211 is fixedly mounted on the right side of the upper end of the synchronization plate 21, and a corrugated groove 212 is opened on the left end of the vertical plate 211 for driving the matching rod 324 to move back and forth.

[0044] The toggle unit 32 is used to toggle the alignment plate 33 back and forth; specifically, when the conveying seat 22 moves to the right along the upper horizontal section of the circular groove 28 to the right limit position, the conveying seat 22 drives the fixed plate 31 to move to the right, and at the same time, the fixed plate 31 drives the matching rod 324 to move to the right to the corresponding position of the vertical plate 211 through the toggle plate 321, and the matching rod 324 can be inserted into the corrugated groove 212. When the conveying seat 22 moves downward along the right vertical section of the circular groove 28, the conveying seat 22 drives the toggle plate 321 to move downward through the fixed plate 31, and at the same time, the matching rod 324 With the cooperation of the corrugated groove 212, the cooperating rod 324 drives the toggle plate 321 to move back and forth, and at the same time, the toggle plate 321 drives the alignment plate 33 to move back and forth through the connecting spring 323, so that the alignment plate 33 drives the positioning device 4 and the stamping part clamped therein to move back and forth, and under the action of the connecting spring 323, the toggle plate 321 applies an elastic force to the alignment plate 33 to move back and forth, and then when the stamping part is precisely fitted on the lower mold 12, the alignment plate 33 no longer drives the stamping part to move back and forth, ensuring that the stamping part and the lower mold 12 can be precisely fitted.

[0045] When the conveying seat 22 moves leftward along the lower horizontal section of the circular groove 28 , the conveying seat 22 finally drives the matching rod 324 to move leftward out of the wave groove 212 through the fixing plate 31 , so that the toggle plate 321 returns to the initial position under the action of the extension spring 322 .

[0046] See also Figure 1 , Figure 7 and Fig. 9The positioning device 4 includes a buffer plate 41 which is slidably installed on the side of the alignment plate 33 close to the middle of the base 1, a return spring 42 is connected between the buffer plate 41 and the alignment plate 33, a clamping unit 43 for clamping the stamping part is installed on the buffer plate 41, a positioning plate 44 is fixedly installed on the right end of the side of the buffer plate 41 close to the middle of the base 1, and a pushing unit 45 for pushing the stamping part to the right is installed on the left end of the side of the buffer plate 41 close to the middle of the base 1; wherein the buffer plate 41 is initially aligned with the alignment plate 33 in the upper and lower centers.

[0047] The positioning device 4 is used to clamp the stamping part and adjust the left and right position of the stamping part; specifically, when the two synchronous plates 21 move in the direction of approaching each other, the synchronous plate 21 finally drives the alignment plate 33 and the buffer plate 41 to move in the direction of approaching each other through the conveying seat 22, and then controls the two clamping units 43 arranged in front and behind to clamp the front and rear ends of the stamping part. At the same time, the pushing unit 45 can push the stamping part to the right, so that the right end of the stamping part is aligned with the positioning plate 44, thereby realizing the left and right position adjustment of the stamping part. When the stamping part is demolded from the lower mold 12, it can prevent the stamping part from causing a slight deviation in the position of the plate due to the change in the shape of the plate due to its elasticity, thereby preventing the accumulation of left and right position errors of the stamping part when the stamping part is continuously conveyed, thereby ensuring the processing accuracy of the stamping part.

[0048] When the conveying seat 22 moves upward along the vertical section on the left side of the circular groove 28, the conveying seat 22 finally drives the clamping unit 43 to remove the stamping part from the lower mold 12 through the fixed plate 31. At the same time, under the action of the return spring 42, the clamping unit 43 can elastically remove the stamping part from the lower mold 12, thereby preventing the stamping part 12 from being deformed when being removed from the lower mold 12, thereby preventing the subsequent processing of the stamping part 12 from being affected.

[0049] When the conveying seat 22 moves downward along the right vertical section of the circular groove 28 to the lower limit position, the conveying seat 22 finally drives the clamping unit 43 to place the stamping part on the lower mold 12 through the fixed plate 31. When the stamping part is not accurately fitted on the lower mold 12, the stamping part cannot continue to move downward due to the interference of the lower mold 12, so that the stamping part drives the buffer plate 41 to move upward through the clamping unit 43, and at this time, the toggle plate 321 applies an elastic force to the alignment plate 33 to move forward and backward, so that the alignment plate 33 applies an elastic force to the stamping part through the buffer plate 41, and when the stamping part moves to When the position is precisely aligned with the lower mold 12, the buffer plate 41 drives the stamping part 12 to move downward through the clamping unit 43 under the action of the return spring 42 so that the stamping part 12 and the lower mold 12 are precisely fitted, and then the clamping unit 43 is controlled to release the stamping part, and the two synchronous plates 21 are controlled to finally drive the clamping unit 43 to move away from each other. When the conveying seat 22 returns to the initial position along the lower horizontal section of the circular groove 28, the clamping unit 43 can return to the initial position, and repeat the above operation, so that the clamping unit 43 can transfer the stamping part to the right to the corresponding position of the adjacent lower mold.

[0050] See also Figure 7 and Figure 8 The clamping unit 43 includes two symmetrical clamping plates 431 slidably mounted on the buffer plate 41 near the middle of the base 1, and the two clamping plates 431 are jointly installed with a No. 2 synchronous screw 432 by threaded cooperation, and the No. 2 synchronous screw 432 is rotatably connected to the buffer plate 41, and the upper end of the No. 2 synchronous screw 432 is fixedly connected to the output shaft of the No. 2 motor 433 fixedly installed in the buffer plate 41.

[0051] The clamping unit 43 is used to clamp the stamping parts; specifically, when the stamping parts need to be clamped, the No. 2 motor 433 is controlled to drive the two clamping plates 431 to move towards each other through the No. 2 synchronous screw 432, so that the clamping plates 431 clamp the stamping parts. When the stamping parts are placed on the lower mold 12, the No. 2 motor 433 is controlled to drive the two clamping plates 431 to move away from each other through the No. 2 synchronous screw 432, so that the clamping plates 431 release the stamping parts.

[0052] See also Figure 7 and Figure 8 The pushing unit 45 includes a square plate 451 which is slidably installed on the left end of the buffer plate 41 near the middle of the base 1.

[0053] The pushing unit 45 is used to push the stamping part to the right; specifically, when the two clamping plates 431 move toward each other and before the two clamping plates 431 clamp the stamping part, the clamping plate 431 located on the upper side drives the U-shaped plate 434 to move downward, so that the inclined surface of the vertical section on the left side of the U-shaped plate 434 drives the square plate 451 to move to the right, and then the square plate 451 drives the pushing plate 454 to move to the right through the square spring rod 453 and fits on the left side of the stamping part, and at the same time the square spring rod 453 is compressed, and then the two clamping plates 431 clamp the stamping part again, and when the two clamping plates 431 take the stamping part out of the lower mold 12, since the clamping force of the clamping plates 431 on the stamping part is relatively small, the pushing plate 454 pushes the stamping part to the right under the action of the square spring rod 453, so that the right end of the stamping part fits with the positioning plate 44.

[0054] See also Figure 3 and Figure 7 An L-shaped rod 46 is fixedly installed on the upper end of the buffer plate 41, and the vertical section of the L-shaped rod 46 slides up and down and passes through the alignment plate 33. Top plates 251 are fixedly installed on the upper ends of the opposite sides of the two back plates 25, and multiple downward pressure blocks 252 evenly arranged on the left and right are fixedly installed on the opposite sides of the lower ends of the two top plates 251. An inclined surface matching the horizontal section of the L-shaped rod 46 is set on the left side of the lower end of the downward pressure block 252.

[0055] When the conveying seat 22 moves upward along the left vertical section of the circular groove 28 to the upper limit position, the conveying seat 22 drives the buffer plate 41 and the L-shaped rod 46 to the upper limit position through the fixed plate 31, so that the horizontal section of the L-shaped rod 46 moves to the corresponding position of the lower pressure block 252. When the conveying seat 22 moves to the right along the upper horizontal section of the circular groove 28, the horizontal section of the L-shaped rod 46 drives the buffer plate 41 to move downward under the action of the inclined surface of the lower pressure block 252. When the L-shaped rod 46 and the lower pressure block 252 are separated, the buffer plate 41 returns to its initial position upward under the action of the return spring 42, and the lower pressure block 252 is provided with multiple ones, so that the buffer plate 41 can shake the stamping part up and down through the clamping plate 431, so that the stamping debris remaining on the stamping part can be shaken off, thereby further improving the stamping processing quality of the stamping part.

[0056] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
