The production method of the production mechanism comprises the following steps:

the feeding process comprises the following steps: before the gasket production work is carried out by using the equipment, the sheet materials on the feeding rollers 23 are pulled out and overlapped together, are placed into the feeding channel 11 and are pressed by the pressing columns 12, and then the equipment is started. Due to the characteristic of the metal material of the plate, when the feeding roller 23 rotates, the plate can be conveyed forwards, and under the action of the pressing column 12, the plate is tightly overlapped without an additional conveying auxiliary mechanism.

Cutting process: the inner cylinder driving motor 45 and the outer cylinder driving motor 44 are started, under the combined action of the outer cylinder transmission gear 46 and the inner cylinder transmission gear 47, the three cutting and pushing assemblies 4 operate together, and the outer cylinder 41 and the inner cylinder 42 rotate in opposite directions. Then the shell 31 descends under the guiding and driving action of the lifting rod 32, when the plate is contacted, cutting is started, and the first material pushing ring 481 of the outer cylinder 41 and the material pushing plate 49 of the inner cylinder 42 are pushed upwards by the cut gasket in the cutting process. At the same time, the cut gasket begins to deburr due to the opposing frictional forces generated by the opposing directions of rotation of the frosted surfaces 43 of the outer and

inner barrels

41, 42.

Material pushing process: when the cutting process is finished, the lower end of the cutting and pushing assembly 4 is located in the blanking hole 111, at the moment, the cutting and pushing assembly 4 stops rotating, and the air cylinder 34 starts to work. The pushing plate column 342 is driven by the output end of the cylinder 34 to abut against the connecting plate 492, and then pushes the connecting plate 492 to slide downward. During the downward sliding, the connecting plate 492 contacts the second stripper ring 483 and pushes the second stripper ring 483 to move downward. And the material pushing plate 49 located on the inner cylinder 42 and the first material pushing ring 481 located on the outer cylinder 41 push the waste material and the gasket to fall down simultaneously.

And (3) screening: the gasket and the waste material fall into the screening device 14 at the same time, since the apertures of the sieve holes 142 on the sieve mesh 141 are larger than the aperture of the central circular hole of the gasket and smaller than the outer circular diameter of the gasket, the gasket can slide down from the oblique sieve mesh 141 to enter the next process, and the waste material is screened through the sieve holes 142 of the sieve mesh 141 and falls into the collection box 143.
