The design and manufacture of the dynamic ring pressing die are aimed at ensuring the dimensional accuracy and surface quality of the dynamic ring, so as to ensure good fitting between the dynamic ring and the static ring and achieve effective sealing.

[0003] In the prior art, the processing of the dynamic ring requires advanced rough machining to obtain the corresponding shape and then subsequent processes. Most of the existing rough machining uses stamping forming. Stamping requires the use of a stamping die. The existing stamping die uses an electric push rod to drive the stamping plate to move down to stamp the steel. It may lead to a low yield rate of workpieces due to inaccurate positioning; and there is no ejection mechanism to eject the formed dynamic ring from the die, which is inconvenient for workers to remove and affects work efficiency.

[0004] Therefore, a pressing die for dynamic ring processing is proposed to solve the above problems. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , the present utility model provides a technical solution: a pressing die for dynamic ring processing, including: a workbench 1, a side of the top of the workbench 1 is fixedly installed with an L-shaped mounting frame 2, a stamping assembly 3 is arranged at the top inside the L-shaped mounting frame 2, a limiting assembly 4 is arranged at the bottom of the stamping assembly 3, a die assembly 5 is arranged on the surface of the workbench 1, and a blanking device 6 is arranged at the bottom of the workbench 1.

[0026] Specifically: The workbench 1 plays a role in supporting and installing.

[0027] In one embodiment, a first installation groove 101 is opened on the surface of the workbench 1, and a second installation groove 102 is opened at the bottom of the workbench 1.

[0028] Specifically: The first installation groove 101 facilitates the installation of the die assembly 5, and the second installation groove 102 facilitates the installation of the blanking device 6.

[0029] In one embodiment, two ends of one side of the L-shaped mounting frame 2 are fixedly installed with support rods 201, and the bottoms of the two support rods 201 are fixedly installed on one side of the surface of the workbench 1.

[0030] Specifically: The support rods 201 play a supporting role on the L-shaped mounting frame 2.

[0031] In one embodiment, the stamping assembly 3 includes a hydraulic cylinder 301. The top of the hydraulic cylinder 301 is fixedly installed at the top inside the L-shaped mounting frame 2. Both sides of the bottom of the hydraulic cylinder 301 are fixedly installed with mounting plates 302. Connecting rods 303 are penetrated and embedded on the surfaces of the two mounting plates 302.

The surface of the limiting plate 304 is movably sleeved on the output end of the hydraulic cylinder 301. One end of each of the two connecting rods 303 is fixedly installed at the top inside the L-shaped mounting frame 2.

[0032] Specifically: After the hydraulic cylinder 301 is started, it drives the first connecting plate 401 to lift and lower. The mounting plate 302 plays a role in mounting and supporting the connecting rod 303. The connecting rod 303 plays a role in mounting and fixing the limiting plate 304. The limiting plate 304 plays a role in limiting the output end of the hydraulic cylinder 301.

[0033] In one embodiment, the limiting component 4 includes the first connecting plate 401. One side of the first connecting plate 401 is fixedly connected to the output end of the hydraulic cylinder 301. Limiting slide rods 402 are movably embedded on both sides of the bottom of the first connecting plate 401. The tops of the two limiting slide rods 402 are respectively fixedly connected to both sides of the bottom of the limiting plate 304. The bottoms of the two limiting slide rods 402 are fixedly installed on the surface of the workbench 1. An upper mold 403 is fixedly installed at the bottom of the first connecting plate 401.

[0034] Specifically: The first connecting plate 401 is limited by the limiting slide rods 402. Driven by the hydraulic cylinder 301, the first connecting plate 401 drives the upper mold 403 to perform stamping downward.

[0035] In one embodiment, the mold component 5 includes a lower mold 501. The lower mold 501 is fixedly embedded at the center inside the first installation groove 101. A top ring 502 is movably sleeved on the surface of the lower mold 501. The surface of the top ring 502 is movably embedded inside the first installation groove 101. Top rods 503 are fixedly installed on both sides of the bottom of the top ring 502. The surfaces of the two top rods 503 movably penetrate through the bottom of the first installation groove 101 and are inside the second installation groove 102. Limiting blocks 504 are fixedly installed on both sides of the bottoms of the two top rods 503.

[0036] Specifically: The top ring 502 is movably sleeved on the surface of the lower mold 501, facilitating the lifting of the moving ring sleeved on the surface of the lower mold 501. The top rods 503 connect the spring 605 and the top ring 502. The limiting blocks 504 cooperate with the limiting grooves 604 to play a role in limiting the top rods 503.

[0037] In one embodiment, the ejecting device 6 includes an electric telescopic rod 601. The top of the electric telescopic rod 601 is fixedly embedded at the top side inside the second installation groove 102. A second connecting plate 602 is fixedly installed at the output end of the electric telescopic rod 601. Connecting sleeves 603 are fixedly installed on both sides of the top of the second connecting plate 602. Limiting grooves 604 are respectively opened on both sides of the surfaces of the two connecting sleeves 603. The two connecting sleeves 603 are respectively movably sleeved on the surfaces of the two top rods 503. The four limiting grooves 604 are respectively movably sleeved on the surfaces of the four limiting blocks 504. Springs 605 are fixedly installed on the bottom sides inside the two connecting sleeves 603. The tops of the two springs 605 are respectively fixedly connected to the bottoms of the two top rods 503.

[0038] Specifically: When the output end of the electric telescopic rod 601 is not working, it is in the extended state. After the hydraulic cylinder 301 drives the upper die 403 to reset after stamping, the electric telescopic rod 601 will start, driving the second connecting plate 602 and the connecting sleeve 603 to contract. The connecting sleeve 603 pushes the ejector rod 503 through the internal spring 605 to lift the stamped moving ring. At the same time, in the case of the reset error of the electric telescopic rod 601, the limit groove 604 can play a certain buffering role and does not affect the stamping of the moving ring.

[0039] Working principle: When using this device to stamp the moving ring, first place the moving ring to be stamped on the surface of the lower die 501. Then, start the hydraulic cylinder 301 through an external controller. After the hydraulic cylinder 301 starts, it drives the first connecting plate 401 and the upper die 403 to descend to squeeze the moving ring sleeved on the surface of the lower die 501 for stamping. A limit plate 304 is sleeved on the output end of the hydraulic cylinder 301 and fixed through the mounting plate 302 and the connecting rod 303 to play a limiting role. At the same time, the two sides of the first connecting plate 401 are limited by the limit slide rods 402 to prevent deviation during the downward pressure of the upper die 403, ensuring the accuracy of stamping positioning and improving production quality. After stamping, through a pre-set program, while starting the hydraulic cylinder 301 to reset using an external controller, the electric telescopic rod 601 will start. The electric telescopic rod 601 starts to drive the connecting sleeve 603 and the spring 605 to push the ejector rod 503 upward through the second connecting plate 602. The ejector rod 503 pushes the top ring 502, thereby driving the stamped moving ring to separate from the lower die 501 upward, facilitating the worker to remove it. Subsequently, the electric telescopic rod 601 starts again to drive the top ring 502 to reset. Through the cooperation of the die assembly 5 and the ejector device 6, it is convenient to remove the moving ring after stamping, improving work efficiency.
