In order to solve the technical problem of above-mentioned existence, the utility model takes following technical proposals: a kind of elasticity filling device, comprise fuselage, knockout rod, damper mechanism and elastic ejection mechanism, it is characterized in that, described fuselage is provided with punching press patrix and punching press counterdie, punching press patrix and punching press counterdie form the diel of workpiece, described knockout rod is connected by damper mechanism with punching press counterdie, described elastic ejection mechanism is by holder, disc spring group and knock-pin composition, described holder divides the both sides being located at fuselage, described disc spring group and holder are socketed, the upper end of described knock-pin is connected with disc spring group, the lower end of knock-pin is provided with the buffer head suitable with knockout rod.
When high velocity ram machine carries out press work, bent axle on fuselage drives punching press patrix to move downward, the press work to workpiece is completed together with the punching press counterdie of underbelly, and can be fitted on punching press patrix at workpiece, workpiece moves upward together with punching press patrix, dnockout bridge is on the top of workpiece, also move upward with workpiece, now the knock-pin of elastic ejection device effectively stops knockout rod and workpiece to move upward, make workpiece and depart from punching press patrix, knockout rod falls back original position, takes out the workpiece that punching press completes, waits for the punching press of next workpiece.Damper mechanism, after workpiece is separated with punching press patrix by knockout rod, prevents knockout rod and punching press counterdie generation rigid collision, both noise was reduced, extend again the service life of knockout rod, effectively reduce dnockout vibration of bar simultaneously, ensure the stationary performance of high velocity ram machine work; Elastic ejection mechanism, effectively stop workpiece and knockout rod to move upward, realize knockout rod and be separated with punching press patrix by workpiece, having flexible feature is to prevent knockout rod generation deformation, extends the service life of knockout rod; Holder, is generally arranged on fuselage by bolt group; Disc spring group, structure is simple, and compared with general spring, its bearing capacity is strong, is specially adapted to large-scale pressing equipment; Have the knock-pin of buffer head, structure is simple, prevents knockout rod generation rigid collision, both reduces noise, extend again the service life of knockout rod.
As preferably, described damper mechanism is made up of shock-absorbing spring and lead, and the two ends of described shock-absorbing spring are connected with knockout rod with punching press counterdie respectively, described lead and shock-absorbing spring suitable, lead and knockout rod are socketed, and lower end and the punching press counterdie of lead fix.Shock-absorbing spring, has the feature of simple structure and good damping effect; Lead, effectively prevents knockout rod displacement in the course of the work, ensures that knockout rod continues to be separated stability and the accuracy of workpiece and punching press patrix.
As preferably, the both sides of described fuselage are respectively equipped with the cushion pad suitable with knockout rod.Cushion pad, structure is simple, reduces knockout rod generation rigid collision further, extends the service life of knockout rod.
As preferably, described elastic ejection mechanism also comprises locating dowel and limiting plate, described locating dowel and disc spring group are socketed, the two ends of locating dowel fix with holder respectively, described limiting plate and locating dowel are socketed, the upper surface of limiting plate and disc spring group close contact, lower surface and the knock-pin of limiting plate fix.By increasing locating dowel and limiting plate, realizing many group disc spring groups can be installed in a holder, to improve the bearing capacity of elastic ejection device, making this elasticity filling device be more suitable for large-scale pressing equipment.
As preferably, in each described holder, be provided with 1-4 group disc spring group.The disc spring group of certain group of number, had both met the designing requirement of bearing capacity, easy for installation again.
Owing to taking above-mentioned technical scheme, a kind of elasticity filling device that the utility model provides has such beneficial effect: by the combined innovation of fuselage, knockout rod, damper mechanism and elastic ejection mechanism and syndeton thereof, there is provided a kind of structure simple, bearing capacity is strong, long service life, stable performance, the low elasticity filling device with being specially adapted to large-scale pressing equipment of noise.
