in practical use, a worker pours a large amount of rivets and nail cores into the rivet vibrating screening disc 2 and the nail core vibrating screening disc 3 respectively, and after vibrating screening operation, the rivets and the nail cores are fed into the rivet feeding vibrating ramp 4 and the nail core feeding vibrating ramp 5 from the discharge port one by one respectively and are fed into the rivet receiving groove 611 and the nail core receiving groove 612 respectively, automatic sleeving operation of the rivets and the nail cores is realized along with rotation of the receiving disc 61, after the sleeving operation is completed, the driving inside the cold header drives the linkage shaft 101 to rotate, so that synchronous rotation of the first driving cam 102 and the second driving cam 103 is realized, further the linkage sliding block 72 is driven to slide on the workbench 1 in a reciprocating manner, the first clamping block 73 and the second clamping block 74 are driven to perform clamping movement, and the sleeved rivets are clamped into the first-stage cold heading operation area 11 and the second-stage cold heading operation area 12, carry out one-level cold-heading operation and second grade cold-heading operation respectively, need not the manual work and carry out material loading one by one and cup joint the operation one by one and shift the station to the rivet body and nail core, improved rivet processing's automation, and then improved rivet processing's efficiency.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
