[0002] Sealing gaskets are made of metal or non-metallic plate materials through cutting, stamping or shearing processes. They are used for sealing connections between pipes and between parts of machinery and equipment. Sealing gaskets can be divided into metal sealing gaskets and non-metallic sealing gaskets according to their material. Metal sealing gaskets are usually produced continuously by die stamping. The continuous production stamping methods usually include single-stage stamping and double-stage stamping. Although the single-stage stamping method can form an annular gasket in one punch, the stamped annular gaskets and circular waste are difficult to classify and collect. Although the double-stage stamping method can facilitate the classification and collection of annular gaskets and circular waste, its production efficiency is relatively low.

Similarly, when the sliding seat 133 drives the upper mold assembly 4 to move upward to reset, the symmetrical fixed serrations 110 drive the symmetrical downward pressing fixed heads 101 to move upward to reset and release the fixing effect through the symmetrical vertical rods 109; When the sealing gasket stamping continuous preparation device drives the upper mold group 4 to move downward for stamping through the sliding seat 133, it can drive the downward pressing fixing head 101 to press down and fix the metal plate 9 before the upper stamping cutting sleeve 42 and the upper buffer head 43 contact the lower buffer sleeve 35 and the lower stamping cutting head 34. When the upper mold group 4 is driven to move upward for reset through the sliding seat 133, it can immediately drive the downward pressing fixing head 101 to move upward and reset to release the fixing effect on the metal plate 9.

[0026] Example 3 like Figure 1-Figure 4 As shown, based on the first and second embodiments, a progressive mechanism 11 for advancing the metal sheet 9 is provided on the top of the bottom workbench 1. The progressive mechanism 11 includes pressing progressive rollers 111 symmetrically provided on the upper and lower sides of the metal sheet 9. The pressing progressive rollers 111 on the upper and lower sides are fixedly connected to roller shafts 112. Both ends of the roller shafts 112 are rotatably connected to the top of the bottom workbench 1. The outside of the roller shaft 112 is symmetrically fixedly connected to meshing gears C113. The meshing gears C113 on the upper and lower sides are meshed with each other. The two meshing gears C113 make the pressing progressive rollers 111 on the upper and lower sides rotate towards each other. The progressive mechanism 11 also includes a connecting plate 114 fixedly connected to the outside of the sliding seat 133, and the lower part of the connecting plate 114 is evenly rotatably connected to a rotating sawtooth 115. The inner side of the rotating sawtooth 115 is provided with an upper limit block 116 for preventing it from deflecting upward, and the outer side of the rotating sawtooth 115 is provided with a return spring 117 for driving it to return upward. The rotating sawtooth 115 can only be deflected downward, and the progressive mechanism 11 also includes a rotating cylinder 118 and a rotating rod 119 rotatably connected to the inside of the top connecting cover 2. The rotating cylinder 118 is located on the outside of the rotating rod 119, and the outside of the rotating cylinder 118 is fixedly connected with an engaging ring gear 120 engaged with the rotating sawtooth 115. The outside of the engaging ring gear 120 is fixedly connected with a force storage torsion spring 121 sleeved on the outside of the rotating cylinder 118, which follows the connecting plate 114 to The downward moving rotating sawtooth 115 can drive the meshing gear ring 120 to rotate to store force. The inner side of the meshing gear ring 120 is symmetrically provided with a driving ratchet groove 122, and the outer side of the rotating rod 119 is symmetrically provided with a groove 123. The internal rotation of the groove 123 is connected to a driving pawl 124. The reset meshing gear ring 120 can drive the rotating rod 119 to rotate by driving the ratchet groove 122 and the pawl 124 to realize material delivery. A pressure spring 125 is fixedly connected between the driving pawl 124 and the groove 123. The rotating rod 119 extends to the outside of the top connecting cover 2 and is provided with a synchronous part B126 between it and the upper roller shaft 112. The synchronous part B126 is a common belt and pulley combination, that is, the rotating rod 119 and the upper roller shaft 112 rotate synchronously through the synchronous part B126.

[0027] In this embodiment: when the sliding seat 133 drives the upper die set 4 to move downward for stamping, the connecting plate 114 and the rotating serrations 115 can follow the sliding seat 133 to move downward and drive the meshing gear ring 120 to rotate inward. The inward rotating meshing gear ring 120 causes the force storage torsion spring 121 to store force. Since the downward pressing fixing head 101 in the second embodiment presses down and fixes the metal plate 9, and the upper stamping cutting sleeve 42 is located inside the stamping hole on the metal plate 9, the pressing and progressive rollers 111 located on the upper and lower sides of the metal plate 9 cannot rotate, that is, the force storage state of the meshing gear ring 120 can be maintained. The sliding seat 133 drives the upper die set 4 to move upward to reset and release the fixing effect of the downward fixing head 101 on the metal plate 9, and when the upper die set 4 is driven to separate from the lower die set 3, the meshing gear ring 120 with stored force will immediately rotate outward. The meshing gear ring 120 rotates outward by driving the ratchet groove 122 and the ratchet pawl 124. The outward rotating rod 119 drives the upper roller shaft 112 to rotate through the synchronous member B126. The meshing gears C113 on the upper and lower sides can make the pressing and advancing rollers 111 on the upper and lower sides rotate toward each other to transfer the material. The upper die set 4 and the lower die set 3 are separated and the material is transferred at the same time, which can prevent the upper die set 4 from sticking and push the annular gasket 6 into the collection box B8 through the progressive advancement of the metal plate 9, thereby assisting in the collection of the annular gasket 6; When the connecting plate 114 and the rotating saw teeth 115 move upward following the sliding seat 133, the meshing gear ring 120 will not be affected because the rotating saw teeth 115 can deflect downward, that is, the metal sheet 9 between the upper and lower pressing progressive rollers 111 maintains a stable state; When the sealing gasket stamping continuous preparation device drives the upper mold group 4 to move downward for stamping through the sliding seat 133, it can drive the meshing gear ring 120 to rotate inward by rotating the serrations 115 to accumulate force, and the accumulated force state of the meshing gear ring 120 can be maintained. When the upper mold group 4 is driven upward by the sliding seat 133 to release the fixing effect of the downward pressing fixing head 101 and make the upper mold group 4 disengage from the lower mold group 3, the meshing gear ring 120 with accumulated force will immediately rotate outward and reset to make the clamping progressive rollers 111 on the upper and lower sides rotate toward each other to deliver the material. While delivering the material, it can prevent the upper mold group 4 from sticking to the material and assist the collection of the annular gasket 6 through the progressive metal plate 9.
