(13) displacement:
About the translation mechanism hand has, clamping and three cylinders of displacement, after workpiece is sent to station to be shifted, the upper and lower air cylinders of the mechanism hand of wait on workpiece downwards → clamp cylinder workpiece is clamped → upper and lower air cylinders upwards → flat-removing air cyclinder arrives to the right and puts band nail retainer station and (put band nail retainer well, ball pocket and rivet all make progress) → upper and lower air cylinders is downward, and the guiding head of this moment band nail retainer rivet inserts in the rivet hole that does not have the nail retainer → clamp cylinder workpiece relievings → upper and lower air cylinders is made progress-→ flat-removing air cyclinder is the most left to being back to.
(14) put band nail retainer:
Laying in the band nail retainer that ball pocket and rivet make progress in the band nail retainer barrel, one escapement is arranged at the bottom of barrel, the all very accurate mould of size, shape, position and a posture is installed on the hopper plate below the barrel, when the every action of escapement once, just put next band nail retainer, this moment, mould had slight vibrations, and retainer is placed in the mould exactly reposefully.(annotate: the rivet of band nail retainer and the rivet hole of retainer are firm interference fit, and the distribution diameter error of ball pocket and rivet, they each other the five equilibrium error and the vertical error between the faying surface of each rivet and retainer, all should be within the range of permission, to guarantee the proper functioning of machine.)
(15) retainer is closed in bat:
When cylinder is downward, claps matched moulds nothing nail retainer and band nail retainer are fitted tightly.(annotate: the rivet of band nail retainer is the less interference fit of magnitude of interference with the rivet hole that does not have the nail retainer.)
(16) check retainer:
Because retainer has certain thickness, the contact of posting a letter, the top of checking the piston rod of cylinder, when cylinder was downward, the contact did not contact when normal condition, and when in the workpiece during no retainer, the contact just contacts, and sends the NG signal.
(17) NG rejects:
After obtaining the NG signal, reject cylinder this workpiece is pushed NG product case.
(18) riveted:
After workpiece was delivered to the riveted station by the riveted counterdie, supercharging gas was downward fast, began with big pressure after near workpiece downwards at a slow speed, and workpiece is carried out riveted.The pressure of riveted can be according to the preset amount of workpiece, if the working pressure of air inlet is 0.4Pa, then riveted pressure can reach 5～10t.On the riveted position, a pressure-bearing post is arranged below the following riveting die, so big power is closed between patrix, workpiece rivet, counterdie, pressure-bearing post and the pressurized cylinder frame, and can not make other because of bearing so big power and be out of shape even damaging.
