Abstract
A level-type bidirectional press for pressing the powder bidirectionally for shaping a workpiece is composed of machine base, machine frame, motor, worm-gear speed reducer, die, die holder, etc. It features that under the action of upper and lower levers, the upper and lower punching heads press the powder in die at same time to form a workpiece with uniform compactness.
Description
One, technical field
The present invention relates to a kind of press that is used for powder compression moulding, refer in particular to a kind of lever press.
Two, background technology
Since the fifties in last century, the lever press of always using till today in China's powder metallurgy production procedure only has uniaxial pressure.Because be uniaxial pressure, downtrodden product mould base top packing height takes place and the low phenomenon of bottom packing, such product mould base flexural deformation phenomenon in various degree often occurs by behind the sintering furnace sintering, causes the percent defective height, and productivity effect is low.
Three, summary of the invention
The objective of the invention is to overcome the defective that above-mentioned prior art exists, provide the automatic retainer of a kind of lever two-way press, its compacting powder makes the unanimity of packing up and down of product mould base, and has the function of automatic picking-up mould base and reinforced easily advantage.
For achieving the above object, the solution that the present invention takes is: the two-way press of the automatic retainer of a kind of lever, comprise support, frame, motor, worm speed reducer, the mould seat, template and mould thereof, it has last pressing system and following pressing system simultaneously, frame and support are set on the support, upper lever fulcrum and following balance pivot are set on the frame, between worm speed reducer and the support two concentric driving wheels are arranged, two concentric driving wheels are connected by eccentric shaft, eccentric shaft is being taken the interruption connecting rod, being interrupted connecting rod is interconnected by the adjusting screw(rod) cover, be interrupted connecting rod one end and connect upper lever, the upper lever stem connects upward ejector beam, and last ejector beam stem is equipped with the upper punch fastening nut, the upper punch fastening nut is held in the mouth tight upper punch, on each concentric driving wheel with eccentric shaft in opposite directions the other end binder cam is housed; Following lever tail is regulated under the relative binder cam of roller nut by one a pair of roller is set, and following lever stem connects the bottom knockout bar, and bottom knockout bar stem is equipped with the low punch fastening nut, and the low punch fastening nut is held in the mouth tight low punch.
When needing the beginning pressing process, actuating motor, worm speed reducer begins to turn clockwise, on the worm speed reducer on two concentric driving wheels eccentric shaft drive and be interrupted connecting rod, the upper lever afterbody is upwards promoted, under the effect of upper lever fulcrum, the upper lever stem will go up the upper punch that ejector beam connects and be pressed in the mould of filling powder; Simultaneously, press to down the roller of lever tail with eccentric shaft binder cam in opposite directions, under the effect of balance pivot down, following lever stem is pressed into the low punch that the bottom knockout bar is connected in the mould of filling powder.Like this, bidirection press is with the powder compression moulding in the mould about just producing, and the packing of mould base is just relatively more consistent up and down.Packing mould base unanimous between the higher and lower levels the flexural deformation phenomenon can not occur in the sintering furnace sintering process, improved finished product rate and productivity effect.
