DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the said features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0036] The utility model provides a stamping die, which is used for stamping blanks to prepare workpieces such as battery poles. Figure 1 and Figure 2 The stamping die of one embodiment includes an upper die unit 100 , a lower die unit 200 and a feeding device. The upper die unit 100 and the lower die unit 200 can be moved closer to or farther away from each other to achieve stamping forming of the workpiece 20 .

[0037] In one embodiment, please refer to Figure 5 The stamping die further includes a plurality of stamping heads 660, which are respectively connected to the upper die unit 100, and the lower die unit 200 is provided with a plurality of forming cavities, which are arranged one by one with the plurality of stamping heads 660. The plurality of stamping heads 660 can perform different stamping processes on the workpiece 20.

[0038] In one embodiment, please refer to Figure 3 and Figure 4 The feeding device is arranged on at least one of the upper die unit 100 and the lower die unit 200 so as to be able to transfer the workpiece 20 to different stations on the lower die unit 200, so that the stamping die can simultaneously perform different stamping processes on the workpieces 20 at different stations, so as to improve the processing efficiency.

[0039] In one embodiment, see Figures 1 to 3 The feeding device includes a rotating platform 310 and a plurality of clamping mechanisms 400 . The plurality of clamping mechanisms 400 are all disposed on the rotating platform 310 and are all used to clamp or release the workpiece 20 . The rotating platform 310 is used to drive the plurality of clamping mechanisms 400 to rotate.

[0040] It can be understood that when several clamping mechanisms 400 clamp each workpiece 20, each workpiece 20 can rotate and move to different workstations following the several clamping mechanisms 400, and the several clamping mechanisms 400 can release each workpiece 20 at different workstations, thereby realizing the transfer of each workpiece 20 between different workstations. Since only one rotating platform 310 is used to realize the transfer of several clamping mechanisms 400 between adjacent processes, only one power component is needed to meet the use requirements of the rotating platform, which can reduce the use of power components and thereby reduce the production cost of the feeding device.

[0041] In one embodiment, see Figures 1 to 3 The feeding device also includes a power assembly 320. The rotating platform 310 and the power assembly 320 constitute a rotating mechanism 300. The power assembly 320 is connected to the rotating platform 310 in a transmission manner and is used to drive the rotating platform 310 to rotate. Each clamping mechanism 400 is distributed at intervals in the circumference of the rotating platform 310, so that each clamping mechanism 400 can be transferred to different positions in the circumference of the rotating platform 310 and correspond to each station of the stamping die, so that a plurality of clamping mechanisms 400 can release each workpiece 20 at a different station, so that the stamping die can perform different stamping processes on the workpiece 20 at different stations. Specifically, the power assembly 320 is a rotating motor or a rotating cylinder to rotate and adjust the rotating platform 310 to meet the use requirements.

[0042] It is understandable that the power assembly 320 can drive the rotating platform 310 to rotate quickly and with high precision, so that the clamping mechanism 400 can drive the workpiece 20 to be quickly transported to different workstations and ensure the accuracy of transporting to each workstation.

[0043] In one embodiment, the feeding device also includes a plurality of clamping drive mechanisms 500, and the plurality of clamping drive mechanisms 500 are arranged in a one-to-one correspondence with the plurality of clamping mechanisms 400. The plurality of clamping drive mechanisms 500 are respectively used to drive the plurality of clamping mechanisms 400 to clamp or release the workpiece 20. The clamping action and opening action of the clamping mechanism 400 are controlled by setting the clamping drive mechanisms 500.

[0044] In one embodiment, see Figure 4The clamping mechanism 400 includes a first clamping plate 410 and a second clamping plate 420 that are arranged opposite to each other. The first clamping plate 410 and the second clamping plate 420 are both slidably arranged on the rotating platform 310 and can approach or move away from each other.

[0045] The plurality of clamping drive mechanisms 500 each include an elastic component 510 and a drive component 520. The elastic component 510 is connected to at least one of the first clamping plate 410 and the second clamping plate 420, and is used to drive the first clamping plate 410 and the second clamping plate 420 to approach each other to clamp the workpiece 20, so that the workpiece 20 can rotate with the clamping mechanism 400. By using the elastic component 510 as the power component of the clamping action of the clamping mechanism 400, the use of the power source can be saved, which is conducive to reducing the production and use costs and saving resources.

[0046] It can be understood that the first clamping plate 410 and the second clamping plate 420 are close to each other so as to accurately position and clamp the workpiece 20 and accurately transport the workpiece 20 to each workstation.

[0047] Specifically, the elastic assembly 510 is provided with two groups, and the two groups of elastic assemblies 510 are connected to the first clamping plate 410 and the second clamping plate 420 respectively, so as to be able to push the first clamping plate 410 and the second clamping plate 420 to approach each other, and use elastic force to drive the clamping action of the clamping mechanism 400. Further, the elastic assembly 510 includes two elastic members 511, and the two elastic members 511 in each group of elastic assemblies 510 are symmetrically arranged on both sides of the first clamping plate 410 or the second clamping plate 420, so as to ensure the stability and reliability of the movement of the first clamping plate 410 and the second clamping plate 420 approaching each other. The elastic member 511 can be a spring or a tension spring.

[0048] In this embodiment, the drive assembly 520 is used to drive at least one of the first clamping plate 410 and the second clamping plate 420 so that the first clamping plate 410 and the second clamping plate 420 can move away from each other to release the workpiece 20, so that the plurality of clamping mechanisms 400 can release each workpiece 20 at different workstations.

[0049] Specifically, the moving direction of the first clamp plate 410 and the second clamp plate 420 approaching or moving away from each other is set at an angle to the moving direction of the driving component 520. Furthermore, the moving direction of the first clamp plate 410 and the second clamp plate 420 approaching or moving away from each other is perpendicular to the moving direction of the driving component 520. Of course, the moving direction of the first clamp plate 410 and the second clamp plate 420 approaching or moving away from each other is set at an angle of 70 degrees, 80 degrees, 100 degrees or 110 degrees to the moving direction of the driving component 520.

[0050] Of course, in other embodiments, the plurality of clamping drive mechanisms 500 may also be drive cylinders, which drive the first clamping plate 410 and the second clamping plate 420 to move closer to or away from each other, thereby realizing the clamping action and the opening action of the clamping mechanism 400 .

[0051] In one embodiment, see Figure 4 The first clamping plate 410 is provided with a first force-bearing rod 411, and the second clamping plate 420 is provided with a second force-bearing rod 421. The driving assembly 520 includes a first driving plate 521 and a second driving plate 522. The first driving plate 521 is provided with a first driving inclined surface 5211, and the second driving plate 522 is provided with a second driving inclined surface 5221. The first driving inclined surface 5211 is used to drive the first force-bearing rod 411 to drive the first clamping plate 410 away from the second clamping plate 420, and the second driving inclined surface 5221 is used to drive the second force-bearing rod 421 to drive the second clamping plate 420 away from the first clamping plate 410.

[0052] In one embodiment, see Figure 4 , there are two first force-bearing rods 411, which are symmetrically arranged on both sides of the first clamping plate 410, and rollers 440 are respectively arranged at the ends of each first force-bearing rod 411, and there are two second force-bearing rods 421, which are symmetrically arranged on both sides of the second clamping plate 420, and rollers 440 are respectively arranged at the ends of each second force-bearing rod 421, and rolling grooves 311 adapted to the rollers 440 are arranged on the rotating platform 310. By setting the rollers 440, the friction force of the first clamping plate 410 and the second clamping plate 420 sliding on the rotating platform 310 can be reduced, thereby reducing the wear between the first clamping plate 410, the second clamping plate 420 and the rotating platform 310, and improving the smoothness of the first clamping plate 410 and the second clamping plate 420 sliding on the rotating platform 310.

[0053] Specifically, two first drive plates 521 are provided, and are arranged one-to-one with each first force-bearing rod 411. The two first drive plates 521 apply a driving force to both sides of the first clamping plate 410, so as to ensure the smooth sliding of the first clamping plate 410 on the rotating platform 310. Two second drive plates 522 are provided, and are arranged one-to-one with each second force-bearing rod 421. The two second drive plates 522 apply a driving force to both sides of the second clamping plate 420, so as to ensure the smooth sliding of the second plate on the rotating platform 310.

[0054] In one embodiment, see Figures 1 to 5, a plurality of driving assemblies 520 are connected to the upper die unit 100, the rotating platform 310, the plurality of elastic assemblies 510 and the plurality of clamping mechanisms 400 are installed on the lower die unit 200; the plurality of driving assemblies 520 are respectively used to drive the plurality of clamping mechanisms 400 to open to release the workpiece 20. By installing the plurality of driving assemblies 520 on the upper die unit 100 and using the upper die unit 100 to drive the plurality of driving assemblies 520 to move, the driving components of the plurality of driving assemblies 520 can be saved, thereby saving production costs.

[0055] It is understandable that when the upper mold unit 100 and the lower mold unit 200 are close to each other, the upper mold unit 100 can drive the first driving plate 521 and the second driving plate 522 to move, so that the first driving plate 521 abuts against the first clamping plate 410 and moves away from the second clamping plate 420, and the second driving plate 522 abuts against the second clamping plate 420 and moves away from the first clamping plate 410, that is, the driving component 520 drives the clamping mechanism 400 to open to release the workpiece 20. When the upper mold unit 100 and the lower mold unit 200 are away from each other, the elastic component 510 can apply an elastic force to the first clamping plate 410 and the second clamping plate 420 to move closer to each other, that is, the clamping mechanism 400 clamps the workpiece 20.

[0056] In one embodiment, please refer to FIG. Figures 1 to 4 The clamping mechanism 400 also includes a limit plate 450. A sliding groove 312 is opened on the rotating platform 310. The limit plate 450 covers the notch of the sliding groove 312 and is enclosed with the groove wall of the sliding groove 312 to form a moving space for limiting the movement of the first clamp plate 410 and the second clamp plate 420. The moving space is used to limit the movement trajectory of the first clamp plate 410 and the second clamp plate 420 approaching or moving away from each other.

[0057] Furthermore, in the present embodiment, two limiting plates 450 are provided, and are respectively arranged corresponding to the first clamping plate 410 and the second clamping plate 420, that is, the first clamping plate 410 and the second clamping plate 420 are respectively limited by one limiting plate 450. The limiting plate 450 includes a first plate body 451 for limiting the first clamping plate 410 or the second clamping plate 420, and a second plate body 452 for limiting the roller 440, the second plate body 452 is connected to the first plate body 451, and an avoidance groove 453 for avoiding the first driving plate 521 or the second driving plate 522 is provided between the second plate body 452 and the first plate body 451, so that it is convenient for the first driving plate 521 to pass through the avoidance groove 453 to drive the first force-bearing rod 411, and it is also convenient for the second driving plate 522 to pass through the avoidance groove 453 to drive the second force-bearing rod 421.

[0058] Specifically, the first clamping plate 410 is provided with a first clamping groove 412 on the side facing the second clamping plate 420, and the second clamping plate 420 is provided with a second clamping groove 422 on the side facing the first clamping plate 410. The groove wall of the first clamping groove 412 and the groove wall of the second clamping groove 422 enclose to form a clamping space for clamping the workpiece 20. After the first clamping plate 410 and the second clamping plate 420 are close to each other, the workpiece 20 is clamped and restricted in the clamping space, which facilitates the clamping mechanism 400 to stably clamp the workpiece 20. Further, the first clamping groove 412 and the second clamping groove 422 are both V-shaped grooves, and the workpiece 20 is columnar. Of course, in other embodiments, the specific shapes of the first clamping groove 412 and the second clamping groove 422 can also be adjusted according to the shape of the workpiece 20. For example, when the workpiece 20 is square, the first clamping groove 412 and the second clamping groove 422 can also be trapezoidal.

[0059] In one embodiment, see Figures 1 to 4 The feeding device is provided with a plurality of processing stations 10 distributed circumferentially, and a plurality of clamping mechanisms 400 are respectively arranged corresponding to the plurality of processing stations 10. The rotating mechanism 300 is used to drive the plurality of clamping mechanisms 400 to transfer to the plurality of processing stations 10 in sequence, so that the plurality of clamping mechanisms 400 can clamp the workpieces 20 at their respective processing stations 10 and release each workpiece 20 at a different processing station 10.

[0060] In this embodiment, a blanking hole is provided on the rotating platform 310, and the plurality of processing stations 10 include a blanking station 13, and the blanking hole is located at the blanking station 13. The feeding device also includes a blanking conveyor belt 610, which is arranged at the blanking station 13, and the workpiece 20 can be blanked from the blanking hole to the blanking conveyor belt 610. The blanking conveyor belt 610 is located below the rotating platform 310 and can convey the stamped workpiece 20 to the next process.

[0061] In one embodiment, see Figures 1 to 3 The feeding device further includes an air blowing pipe 620 and a waste conveyor belt 630. The air blowing pipe 620 is arranged at the unloading station 13. The waste conveyor belt 630 is also arranged near the unloading station 13. The air blowing pipe 620 is used to blow the waste part of the workpiece 20 onto the waste conveyor belt 630. The air blowing pipe 620 can be suspended above the rotating platform 310 to facilitate the blowing of the waste part generated when punching the workpiece 20.

[0062] Specifically, a connecting hole 313 is provided at the center of the rotating platform 310, and the bracket can extend from the connecting hole 313 to the top of the rotating platform 310 and is used to support the air blowing pipe 620. The extension direction of at least part of the extended belt body in the waste conveyor belt 630 is the same as the direction of the air port of the air blowing pipe 620, so that the waste conveyor belt 630 can better receive the waste part blown to it by the air blowing pipe 620.

[0063] In one embodiment, see Figures 1 to 4 , several processing stations 10 include a loading station 11; the feeding device also includes a lifting mechanism 650 and a loading device 640, the loading device 640 is arranged near the loading station 11, and is used to load the workpiece 20 to the lifting mechanism 650, the lifting mechanism 650 is used to lift the workpiece 20 to the loading station 11, and the clamping mechanism 400 is used to clamp the workpiece 20 at the loading station 11, so that the workpiece 20 can be loaded from the loading device 640 to the feeding device. It can be understood that the rest of the several processing stations 10 are stamping stations 12, and after the several clamping mechanisms 400 release the workpiece 20 from the stamping station 12, the workpiece 20 is subjected to different stamping processes by the stamping die. Specifically, the loading device 640 is a vibrating plate feeding device.

[0064] In this embodiment, there are four processing stations 10, which are arranged in sequence along the circumferential direction as a loading station 11, two stamping stations 12, and a blanking station 13. It can be understood that the two stamping stations 12 respectively perform stamping processing on the workpiece 20. Of course, according to the design requirements of the stamping die, one or more of the loading station 11 and the blanking station 13 can also perform stamping processing on the workpiece 20. Of course, in other embodiments, there can be three, five or more processing stations 10, and the specific number of processing stations 10 can be adjusted according to the design requirements of the stamping die.

[0065] See also Figures 1 to 5 When the punching die of the utility model is used, the following actions are specifically included:

[0066] S710, the stamping die closes, the upper die unit 100 moves closer to the lower die unit 200, and the upper die unit 100 drives the driving components 520 to move closer to the corresponding clamping mechanisms 400, so that the clamping mechanisms 400 open; the loading device 640 feeds the workpiece 20 to the bottom of the clamping mechanism 400 at the loading station 11, and the lifting mechanism 650 lifts the workpiece 20 to the clamping mechanism 400 at the loading station 11.

[0067] S730, the stamping die opens, the upper die unit 100 moves away from the lower die unit 200, and the upper die unit 100 drives the driving components 520 to move away from the corresponding clamping mechanisms 400, thereby causing the clamping mechanisms 400 to perform clamping actions. At this time, the clamping mechanisms 400 at the loading station 11 clamp the workpiece 20.

[0068] Next, the power assembly 320 drives the rotating platform 310 to rotate rapidly, so as to transfer the workpiece 20 at the loading station 11 from the loading station 11 to the first stamping station 12 .

[0069] S750, the stamping die closes, the upper die unit 100 moves closer to the lower die unit 200, and the upper die unit 100 drives the driving components 520 to move closer to the corresponding clamping mechanisms 400, so that the clamping mechanisms 400 open. At this time, the clamping mechanism 400 at the first stamping station 12 releases the workpiece 20, and the workpiece 20 falls into the forming cavity at the first stamping station 12 under the action of gravity.

[0070] Next, the punch head 660 on the upper mold unit 100 punches the upper end of the workpiece 20. As the upper mold unit 100 continues to press the lower mold unit 200, the workpiece 20 is formed into a preset size by the inner wall of the molding cavity and the punch head 660.

During this process, the demolding pins arranged in the lower die unit 200 lift the workpiece 20 in the forming cavity of the first stamping station 12 to the clamping mechanism 400, and then the clamping mechanism 400 at the first stamping station 12 clamps the workpiece 20.

[0072] Subsequently, the power assembly 320 drives the rotating platform 310 to rotate rapidly, so as to transfer the workpiece 20 at the first stamping station 12 from the first stamping station 12 to the next stamping station 12 .

[0073] S790, repeatedly performing the opening and closing operations of the stamping die until the workpiece 20 is transferred to the unloading station 13.

[0074] At the unloading station 13, the processed workpiece 20 is unloaded onto the unloading conveyor belt 610 through the unloading hole under the action of gravity. The remaining scraps from the workpiece 20 are blown onto the scrap conveyor belt 630 by the air pipe 620 and transported to the scrap position through the scrap conveyor belt 630, and the cycle repeats.

[0075] The above is the movement process of a single workpiece 20 from the loading station 11 to the unloading station 13. In actual use, each processing station 10 will simultaneously perform actions such as releasing, punching, lifting, clamping and rotation transfer to improve processing efficiency.

[0076] The stamping die of this embodiment performs the above steps to achieve accurate positioning and rapid transportation of the workpiece 20 between various stations. When debugging the feeding device, it only needs to be aligned with one station, without adjusting each station, which greatly simplifies the debugging process. During the processing, each station can work synchronously to improve the processing efficiency.

[0077] In this embodiment, the feeding device uses a rotating platform 310 to drive a plurality of clamping mechanisms 400 to rotate, which has a simple structure and occupies a small space, which is conducive to the spatial arrangement of the feeding device and the stamping die. The feeding device of this embodiment has the advantages of low manufacturing cost, high positioning accuracy, fast handling speed, high degree of automation, etc. and can be widely used in stamping dies.

[0078] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
