DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the embodiments.

[0027] See also Figure 1-6 The utility model provides a stamping device for producing bearing sealing rings, comprising a workbench 1, a support plate 11 being fixed to the upper edge of the workbench 1, an extension plate 12 being fixed to the top of the support plate 11, a lower mold 2 being installed on the upper side of the workbench 1, a die assembly 3 for performing stamping and demoulding processes being installed on the lower side of the extension plate 12, the die assembly 3 comprising a cylinder 31 fixed to the upper side of the extension plate 12, a lifting platform 32 being fixed to the output end of the cylinder 31 passing through the extension plate 12, limit plates 33 being fixed to the upper and lower ends of the lifting platform 32, a protective cover 34 being fixedly connected to the outer side of the lifting platform 32 and located on the lower side of the extension plate 12;

[0028] Specifically, when the cylinder 31 is started, its output end drives the lifting platform 32 to descend, so that the stamping groove 41 of the upper mold 4 cooperates with the convex ring 21 of the lower mold 2 for stamping. After the stamping is completed, the cylinder 31 drives the lifting platform 32 to rise, and the guide rod 36 assists in demolding. Among them, the limit plate 33 can prevent the lifting platform 32 from exceeding the safe stamping range, thereby ensuring the safety of stamping.

[0029] Furthermore, corresponding through holes 35 are provided at the edges of the lifting platform 32 corresponding to the demoulding holes 42. Guide rods 36 are slidably embedded in the through holes 35. The top ends of the guide rods 36 are fixed to the extension plate 12, and the bottom ends of the guide rods 36 correspond to the adjacent demoulding holes 42.

[0030] Specifically, during the stamping process, the cylinder 31 drives the lifting platform 32 downward, allowing the stamping groove 41 of the upper die 4 to mate with the convex ring 21 of the lower die 2, thereby stamping out the bearing sealing ring. After the stamping is completed, the cylinder 31 drives the lifting platform 32 upward. At this time, the guide rod 36, guided by the through hole 35, pushes the stamped bearing sealing ring out of the stamping groove 41, achieving demolding.

[0031] Furthermore, the die assembly 3 is provided with a liftable upper die 4, wherein the lower die 2 and the upper die 4 are arranged in pairs, the upper die 4 is fixed to the lower end surface of the lifting platform 32 by screws, and the lower die 2 is fixed to the upper side of the workbench 1 by screws, and a stamping groove 41 is opened on the lower side of the upper die 4, and a plurality of demoulding holes 42 are opened on the stamping groove 41;

[0032] Specifically, the lower mold 2 and the upper mold 4 can be easily disassembled, and molds of different specifications can be quickly replaced according to production needs, and can quickly adapt to different product specifications.

[0033] Furthermore, a convex ring 21 is fixedly connected to the upper side of the lower mold 2, and the convex ring 21 is adapted to the structure of the stamping groove 41;

[0034] Specifically, the convex ring 21 is matched with the stamping groove 41 of the upper die 4 to ensure that the sealing ring material can be accurately punched out during stamping.

[0035] Furthermore, a reciprocating assembly 5 is connected between the workbench 1 and the die assembly 3. The reciprocating assembly 5 is used to drive the receiving plate 6 to move to the bottom of the upper mold 4 during the demoulding process. The reciprocating assembly 5 includes a fixed rod 51 embedded in the upper side of the workbench 1 and a sliding rod 52 fixed on the limit plate 33 on the lower side of the lifting platform 32. A rotating sleeve 53 is rotatably sleeved on the outer side of the top of the fixed rod 51. A spiral groove 54 is provided on the outer side of the rotating sleeve 53. A connecting plate 55 is fixedly sleeved on the outer side of the bottom end of the rotating sleeve 53. The end of the connecting plate 55 away from the rotating sleeve 53 is fixed to the receiving plate 6. The end of the sliding rod 52 away from the lifting platform 32 extends to the spiral groove 54.

[0036] Specifically, when the cylinder 31 is started and drives the lifting platform 32 to descend for stamping, the slide rod 52 moves in the spiral groove 54, and the cooperation of the rotating sleeve 53 and the fixed rod 51 is used to realize the swing of the receiving plate 6 so as to catch the stamped bearing sealing ring during demolding. After the stamping is completed, the cylinder 31 drives the lifting platform 32 to rise, and the slide rod 52 moves in the opposite direction. The spiral groove 54 makes the rotating sleeve 53 drive the connecting plate 55 and the receiving plate 6 to swing in the opposite direction, and the bearing sealing ring is removed from the receiving plate 6 and falls into the material frame below, realizing the automatic demolding and material receiving cycle process. This design improves production efficiency, reduces manual operation, and also reduces safety hazards in the production process.

[0037] Furthermore, an arc-shaped groove 61 is formed on the receiving plate 6, an extension plate 13 is fixedly connected to one side of the workbench 1, and a stop rod 14 is fixedly connected to the upper side of one end of the extension plate 13 away from the workbench 1, and the stop rod 14 is located on the moving track of the arc-shaped groove 61;

[0038] Specifically, when the receiving plate 6 swings to the baffle 14, the baffle 14 will prevent the sealing ring from swinging further. As the receiving plate 6 swings, the bearing sealing ring can fall off from the receiving plate 6 and fall into the pre-prepared material frame to facilitate the collection of the stamped products.

[0039] Working principle: When in use, place the sealing ring diaphragm in the position to be punched, start the cylinder 31, and the cylinder 31 drives the lifting platform 32 to descend, so that the convex ring 21 is embedded in the punching groove 41, and the bearing sealing ring of the required size can be punched out. After the punching is completed, the cylinder 31 drives the lifting platform 32 to rise. In this process, the bearing sealing ring intercepted in the punching groove 41 rises along with the lifting platform 32 until the guide rod 36 conflicts with the bearing sealing ring, which can assist the bearing sealing ring to be demoulded. At the same time, the sliding rod 52 rises along with the upper mold 4, and the sliding rod 52 is pushed away. The rod 52 squeezes the inner wall of the spiral groove 54, so that the rotating sleeve 53 drives the receiving plate 6 to swing to the bottom of the upper mold 4. The bearing sealing ring after demoulding can fall to the upper side of the receiving plate 6. Then, the position of the sealing ring diaphragm to be punched is adjusted, and the lifting platform 32 is lowered again. The sliding rod 52 squeezes the inner wall of the spiral groove 54 in the opposite direction, so that the rotating sleeve 53 drives the receiving plate 6 to swing in the opposite direction until the blocking rod 14 contacts the bearing sealing ring, causing the bearing sealing ring to fall into the pre-prepared material frame. Repeating the above steps can complete the batch production of bearing sealing rings.
