Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Referring to Figures 1-4 , a stamping die capable of assisting in end plate blanking includes a base 1. A die assembly 2 is arranged on the upper surface of the base 1. Two elastic telescopic rods 3 are fixed to the upper surface of the base 1 by bolts. The tops of the two elastic telescopic rods 3 are fixed to the same bearing plate 4 by bolts. The bearing plate 4 is composed of a front bottom plate, a top plate and a rear bottom plate. A connecting plate 5 is fixed to the bottom of the bearing plate 4 by bolts. A plurality of limiting plates 6 are fixed to the upper surface of the connecting plate 5 by bolts. A fixing frame 7 is fixed to the upper surface of the base 1 by bolts. A guide groove is formed in one inner wall of the fixing frame 7. A sliding seat 8 is slidably connected in the guide groove. A movable wheel 9 is rotatably connected between the two inner walls of the sliding seat 8. The movable wheel 9 rolls on the front bottom plate of the bearing plate 4. Through the design of the movable wheel 9 rolling on the bearing plate 4, it can ensure the smoothness of the movable wheel 9 rolling on different positions of the front bottom plate, the top plate or the rear bottom plate of the bearing plate 4, and ensure the smooth sliding of the bearing plate 4. An upper motor 10 is fixed to the upper surface of the sliding seat 8 by bolts. A connecting rod 11 is fixedly sleeved on the output end of the upper motor 10. During the movement of the connecting rod 11, the limiting plate 6 can be slid downward before the connecting rod 11 toggles the end plate to blank, avoiding the blocking of the limiting plate 6 on the blanking of the end plate and facilitating the production and use of the end plate.

[0024] The mold assembly 2 includes a lower mold 201, which is fixed to the upper surface of the base 1 by bolts. A lower hydraulic cylinder 202 is fixed to the bottom inner wall of the lower mold 201 by bolts, and the top of the hydraulic rod on the lower hydraulic cylinder 202 is fixed to a backing plate 203 by bolts. A support frame 204 is fixed to the upper surface of the base 1 by bolts, and an upper hydraulic cylinder 205 is fixed to the upper surface of the support frame 204 by bolts. The bottom of the hydraulic rod on the upper hydraulic cylinder 205 is fixed to an upper mold 206 by bolts, and the upper mold 206 is vertically aligned with the lower mold 201. The backing plate 203 is combined with the upper mold 206, which can clamp the end plate before and after stamping to prevent position deviation. The connecting plate 5 is slidably sleeved on the outer surface of the lower mold 201, and a plurality of limiting plates 6 are respectively located on the four sides of the lower mold 201, and the top of the limiting plate 6 is higher than the top of the lower mold 201. Through the design of the limiting plate 6, when placing the blank plate on the lower mold 201 before stamping the end plate, it can be limited to ensure the alignment of the end plate production.

[0025] A threaded rod 12 is rotatably connected between the inner walls on both sides of the fixing frame 7, and a sliding seat 8 is threadedly sleeved on the outer surface of the threaded rod 12. Rotating the threaded rod 12 facilitates the fine operation of the sliding seat 8. A side motor 13 is fixed to the outer wall of one side of the fixing frame 7 by bolts, and the output end of the side motor 13 is connected to one end of the threaded rod 12 by a coupling.

A plurality of support rods 14 are fixedly inserted into the upper surface of the base 1, and the support rods 14 are slidably connected to the connecting plate 5. The design of the support rods 14 can guide the sliding of the connecting plate 5, thereby ensuring the stability of the sliding of the connecting plate 5 and the limiting plates 6 thereon.

[0026] The working principle of this embodiment: When producing the end plate, the operator first places the blank plate on the lower mold 201 and the blank plate is located between a plurality of limiting plates 6. Then, the operator drives the backing plate 203 and the upper mold 206 to slide towards the blank plate through the lower hydraulic cylinder 202 and the upper hydraulic cylinder 205 respectively, and the blank plate is clamped by the backing plate 203 and the upper mold 206. Then, the operator slides the blank plate into the lower mold 201 through the lower hydraulic cylinder 202 and the upper hydraulic cylinder 205. At this time, both sides of the blank plate are warped until the blank plate is stamped and formed in the lower mold 201 to form an end plate. Then, under the action of the lower hydraulic cylinder 202 and the upper hydraulic cylinder 205, the end plate moves upward between the backing plate 203 and the upper mold 206 until the end plate disengages from the lower mold 201. Then, under the action of the upper hydraulic cylinder 205, the upper mold 206 slides upward until the upper mold 206 disengages from the end plate. At this time, the end plate is located on the backing plate 203. In this way, the production and use of the end plate are completed.

[0027] When it is necessary to cut the end plate after production, the operator first starts the side motor 13, and then the threaded rod 12 rotates, driving the sliding seat 8 to slide along the guide groove until the sliding seat 8 slides to the top of the supporting plate 4. Under the pressure of the movable wheel 9, the supporting plate 4 slides downward, and the connecting plate 5 connected thereto and the limiting plate 6 thereon slide downward at the same time. At this time, the elastic telescopic rod 3 is in a compressed state, and the top height of the limiting plate 6 is lower than the top height of the lower mold 201. The sliding seat 8 continues to slide forward, and the connecting rod 11 thereon immediately pushes the end plate off the pad 203, completing the cutting and use of the end plate, and the sliding When the seat 8 slides to the position of the rear bottom plate, the movable wheel 9 will not press on the bearing plate 4, and the compressed elastic telescopic rod 3 will stretch out, so that the bearing plate 4, the connecting plate 5 and the limit plate 6 thereon are reset. Then, the end plate can be produced again through the mold assembly 2, and the operator can start the upper motor 10, the upper motor 10 drives the connecting rod 11 to rotate 90 degrees, and reversely start the side motor 13 to drive the threaded rod 12 to rotate, so that the sliding seat 8 slides and resets, and then start the upper motor 10 to make the connecting rod 11 rotate 90 degrees in the opposite direction. At this time, the stamping mold is in a reset state as a whole, and the blanking operation after the end plate production is completed.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
