Bottom roller separator 72 mainly comprises separation cylinder 721, limited block 722, slide block 723 and connecting plate 724.Outermost rolling wheel 732 down is installed on the slide block 723, and slide block 723 is fixedlyed connected with connecting plate 724.Slide block 723 is in the chute, and along with the action of separation cylinder 721 moves forward and backward in chute.The output of separation cylinder 721 links to each other with connecting plate 724, the outermost rolling wheel 732 down of separation cylinder 721 controls moves, limited block 722 is installed in the outer end that side plate 731 is installed in roll riveting, its purposes is to prevent that separation cylinder 721 from pulling out outermost down rolling wheel 732 transition, and promptly anti-limited slip block 723 is deviate from chute.Outermost down rolling wheel 732 separated cylinders 721 will be pulled out back itself and adjacent following rolling wheel 732 and the gap just occurred, the impeller that roll riveting is finished just falls from gap location, discharging opening on the frame 1 just is arranged on the below of gap location, bottom roller separator 72 has made things convenient for the taking-up of impeller after the roll riveting, for producing the condition of having created continuously.

Above-mentioned down rolling wheel 732 is two groups, and one group is installed on roll riveting and installs on the side plate 731 and link to each other with gear train 734, and gear train 734 links to each other with the roll riveting motor, the rotation torque when the impeller roll riveting is provided.Another group and slide block 723 assembling, slide block 723 be along with the output of separation cylinder 721 is made back and forth movement, and after roll riveting was finished, separation cylinder 721 work broke away from rolling wheel 732 down and transmission idle wheel on the gear train 734, and rolling wheel 732 separates under two groups.The direction that material bearing shelf 64 tilts is over against impeller roll riveting mechanism 7, and rolling wheel 732 under the outlet correspondence of material bearing shelf 64, just falls into down on the rolling wheel 732 later in impeller rolls down from material bearing shelf 64.Roll riveting motor and hydraulic system are installed on the frame 1, and the hydraulic oil pipe on the hydraulic system links to each other with roll riveting oil cylinder 745, the roll riveting motor be connected gear train 734 by the rolling riveter belt pulley.

During use, billot blade one end is shut down inductive switch 211 by lacking material, in the roll extrusion wheels 27 of the blade forming mechanism 2 of packing into.Live 27 pairs of billot blades of roll extrusion wheels by four and carry out the roll extrusion processing, the size of pressure is regulated by hold-down devices 29, forms the blade of radian unanimity, and carries out alignment by the blade after 26 pairs of rolls forming of adjuster and handle.To send in the shearing device 31 of blade shut-off mechanism 3, blade is cut off by cutting off die 312 and movable punch 311.Feedstock direction is that the shearing device 31 on the left side does not produce waste material with the cut-out of the blade after the moulding, 31 head waste materials excisions of the shearing device on the right with the moulding rear blade, and waste material is discharged from relief hole.The blade pass of cutting off moulding is crossed material casting device 32 and is thrown into blade and wears in the bearing material storehouse 435 of merry-go-round type bunker device 43 of sheet mechanism 4, whenever a slice of dishing out blade, rotary cylinder 434 control merry-go-round type bunker devices 43 rotate once, successively 435 li each blade grooves in bearing material storehouse are all filled.The merry-go-round type bunker device 43 of filling blade under the effect of servomotor 41 with merry-go-round type bunker device 43 transpositions of an other side, another merry-go-round type bunker device 43 continues to accept the blade that material casting device 32 is dished out.Mid-game is packed in the mid-game draw-in groove of mid-game position-limited rack 60, and the quantity of impeller mid-game can be adjusted according to mid-game position-limited rack 60.Impeller inserted sheet mechanism 5 action, the blades that will fill by push rod 55 in that merry-go-round type bunker device 43 of blade push in the mid-game that is pre-assembled, and this moment, blade was packed in the blade groove of mid-game.Mid-game divides branch dish cylinder 61 actions of disc mechanism 6, and branch dish cylinder 61 moves on guide rail 66 by shift fork 67 control mid-game position-limited racks 60, is about to mid-game distance on request separately.Then retainer cylinder 62 actions, retainer cylinder 62 holds up impeller with impeller carriage 65 jack-up until impeller carriage 65, and height is seasonable with 64 pairs of material bearing shelfs, impeller carriage 65 is towards material bearing shelf 64 deflections, impeller rolls into material bearing shelf 64, rolls into impeller roll riveting mechanism 7 along material bearing shelf 64, just falls into down on the rolling wheel 732 later in impeller rolls down from material bearing shelf 64, following rolling wheel 732 high speed rotating, last rolling wheel 743 is descending to carry out roll riveting to impeller and fixes.Go up rolling wheel 743 after roll riveting is finished and return, the outermost rolling wheel 732 down on the slide block 723 is pulled out in separation cylinder 721 actions, and the impeller after the moulding falls into from gap location and falls, and sends by the deflector chute on the frame.Repeat said process, do roll riveting work next time.

Above-mentioned enforcement only is this patent embodiment preferably, for example to wear the merry-go-round type bunker device 43 in the sheet mechanism 4 also can be 3 groups, 4 groups, 5 groups, 6 groups or more groups to blade, with a certain fulcrum is the center, and servomotor 41 is that center rule rotation gets final product by the many groups of gear-box 42 controls merry-go-round type bunker 43 with this fulcrum; The roll riveting oil cylinder 745 of last roll riveting device 74 also can adopt the structure of cylinder.The protection domain that all belongs to this patent is modified in the structure that all employing the technical program are described, feature and the variation on its spiritual principle.
