[0016] The advantages and features of the present application will be more apparent from the following detailed description of preferred embodiments of the present application, taken in conjunction with the accompanying drawings, in which:

[0017] Please refer to Figures 1 to 4 The embodiments of the present application include:

[0018] A stamping die for processing electrode plate grid capable of automatically removing stamping waste, comprising an upper die seat 1, a lower die seat 2, a punch 3, a die 4, a push plate 5 and a push plate reciprocating driving device installed in the die, wherein the upper die seat 1 is hoisted at the top of the die, the lower die seat 2 is fixed directly below the upper die seat 1, the punch 3 is installed on the upper die seat 1, the die 4 is fixed on the lower die seat 2, a plurality of stamping strips are formed on the punch 3 according to the shape of the grid electrode plate, the die 4 is divided into two layers, from top to bottom, a forming plate 401 and a blanking plate 402, a forming groove is formed on the forming plate 401 corresponding to the stamping position of the stamping strip, a blanking groove corresponding to the forming groove is formed on the blanking plate 402, a push hole 403 is formed through the front end groove plate and the rear end groove plate of each blanking groove, a push rod 501 corresponding to all the push holes 403 is arranged in parallel on the push plate 5, the end of all the push rods 501 on the push plate 5 is inserted into the corresponding push hole 403, the push plate reciprocating driving device is installed between the upper die seat 1 and the lower die seat 2, which can drive the push plate 5 to reciprocate with the stamping action of the upper die seat 1, so that the push rod 501 can push the stamping waste in the blanking groove out of the opening position of the front end of the blanking groove, and the cleaning action is completed.

[0019] There are two push plate reciprocating drive devices, which are symmetrically installed on both sides of the die 4. Each push plate reciprocating drive device includes a driving wheel disc 8, a wheel disc seat 6 and a gear torque converter 7. The wheel disc seat 6 is fixed to the lower die base 2 close to the outer side of the rear part of the die 4, and the driving wheel disc 8 is installed at the front end of the wheel disc seat 6. The gear torque converter 7 is installed at the rear end of the wheel disc seat 6. The driving wheel disc 8 and the upper die base 1 are connected by a first crank connecting rod 9. The first crank connecting rod 9 is located on the inner side of the driving wheel disc 8. The driving wheel disc 8 is connected to the power input end of the gear torque converter 7 through a second crank connecting rod 10. The second crank connecting rod 10 is arranged on the inner side of the driving wheel disc 8. A transmission rod 11 is installed at the power output end of the gear torque converter 7. A transmission gear is provided on the top of the transmission rod 11. Gear bars matching the transmission gear are symmetrically installed on both sides of the push plate 5. With this structure, when the upper die base 1 is pressed downward, the first crank connecting rod 9 rotates the driving wheel 8 as the upper die base 1 moves. The rotation of the driving wheel 8 in turn drives the second crank connecting rod 10 to move, inputting power into the gear torque converter 7. The power output end of the gear torque converter 7 can drive the transmission rod 11 to rotate. The meshing action between the gear and rack drives the pusher plate 5 forward, pushing the waste material in the blanking chute out of the blanking chute. When the upper die base 1 is reset, the pusher plate 5 is also reset accordingly.

[0020] The transmission gear is a worm wheel, and the gear bar is a corresponding worm bar 503. The reason for choosing a worm wheel and a worm bar for the transmission structure is that, on the one hand, the worm wheel and the worm have a large transmission ratio and more stable pushing. On the other hand, the inclined surface structure of the worm causes the force-bearing surface to be forced outward in the horizontal direction, making it less likely to fall off. The combination of a simple gear and a rack does not have direct contact between the pusher plate 5 and the surface of the lower die base 1 below, and there is no sufficient support. During long-term use, it is easy to bend and deform, resulting in difficulty in pushing or even slipping, and cannot be pushed directly.

[0021] The push plate 5 includes a handle 502 and a push rod 501. The handle 502 is a rectangular hollow frame structure. The push rod 501 is mounted on the inner long side of the handle 502. The worm gears 503 are symmetrically mounted on the short sides of the handle 502. The hollow handle on the push plate 5 facilitates on-site loading and unloading, and the short sides of the rectangular handle 502 make it easier to install the symmetrical worm gears 503.

[0022] A laser sensor is installed inside the top of the push rod 5. The function of the laser sensor is to confirm whether the waste in the blanking chute has been completely pushed out of the chute after the pushing action is completed. If there is waste stuck at the open end of the blanking chute and cannot be released, the laser sensor will automatically send a signal to the automatic controller to suspend the stamping action and continue after the on-site personnel have dealt with it.

[0023] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
