Abstract
The utility model relates to an asynchrony pressurizing mechanism of a powder forming machine, which is arranged on a die carrier, and comprises an upper plunger, and a transmission device and a driving device, which drive the upper plunger to move, a floating cavity block which is arranged below the upper plunger and a driving device which drives the floating cavity block to move, and a chock block which is arranged on the lower part of the cavity block to restrict the movement of the cavity block, wherein the die carrier is also provided with synchronic suppression travel mechanism for controlling the upper plunger and the cavity block to synchronically suppress the work travel and a chock block adjusting mechanism for controlling the position of the chock block. The powder is processedby asynchrony three-time pressurizing, so that the upper part, the lower part and the middle part of a pressed compact can maintain the homogenous density, the mechanical property of the pressed compact can be effectively improved, and the following processing and the quality of the product can be ensured.
Description
Technical field
The utility model relates to pressing mechanism, relates in particular to the non-while pressing mechanism of make-up machine.
Background technology
In the powder compacting processing, the uniformity of green density is the key property of its quality, and the homogeneity of the intensity of goods, hardness and each several part performance behind the sintering all depends on the uniformity coefficient of Density Distribution.In addition, the green density skewness will make goods inside produce very big stress when the sintering, thereby causes inhomogeneous, the warpage of shrinking, even cracks.Therefore, during press forming, should make every effort to green density is evenly distributed.The compacting of present powder compacting has following several mode usually: (1) unidirectional compacting: during unidirectional compacting, former and bottom punch are motionless, by the unidirectional pressurization of upper punch.In this case, the two ends density unevenness is even up and down because of the effect of frictional force makes goods.The pressed compact diameter is big more or highly more little, and the density contrast of pressed compact is more little.The advantage of unidirectional compacting is that mould is simple, easy to operate, productivity ratio is high; Shortcoming is only to be suitable for suppressing goods highly little or that wall thickness is big.(2) two-way compacting: during two-way compacting, former maintains static, and upper and lower mould dashes with equal and opposite in direction, pressure that direction is opposite and pressurizes simultaneously.This pressed compact intermediate density is low, and two ends density is high and equal, just looks like two unidirectional pressed compacts that condition is identical, couples together the same from afterbody.So the pressed compact of two-way compacting is permitted to double than unidirectional pressed compact, is suitable for suppressing long goods.The another kind of mode of two-way compacting is after unidirectional compacting finishes, and carries out once reverse unidirectional compacting again at a low density end, to improve the uniformity of green density.This mode is called the back again presses, and can realize two-way compacting on the forcing press of unidirectional pressurization.(3) unsteady mold pressing system: former by spring-loaded, in pressing process, bottom punch maintains static, on upper punch, pressurize at the beginning, along with powder is compressed, the friction between former wall and powder increases gradually, when frictional force becomes supporting force greater than spring, former promptly descends with upper punch, realizes two-way compacting.More than several modes all have the defective of green density skewness, influence following process and quality of item.
The utility model content
The utility model is at above-mentioned defective, and purpose is to provide a kind of green density that can make to keep evenly, thereby guarantees the non-while pressing mechanism of powder former of quality of item.
The technical solution of the utility model is: the utility model is arranged on the mould bases, the transmission device, the drive unit that comprise upper punch and its motion of drive, be arranged on the floating die and the drive unit that makes its motion of upper punch below, be arranged on the block of its motion of former lower limit, also be provided with control upper punch and former on the mould bases and suppress the synchronous pressing stroke mechanism of impulse stroke and the block guiding mechanism of control block position synchronously.
Make the drive unit of former motion adopt synchronous oil pressure actuated.
The utility model adopts the processing of three pressurization formation of non-while to body of powder, make pressed compact top and the bottom, each position, middle part all can keep uniform density, effectively raise the mechanical property of pressed compact, thereby provide solid assurance for the following process and the quality of goods.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
1 is that crank, 2 is that synchronous pressing stroke guiding mechanism, 3 is that compacting bar, 4 is that compaction piston bar, 5 is that block, 6 is that upper punch, 7 is oil cylinder synchronously among the figure.
Below in conjunction with accompanying drawing the utility model is described further
The specific embodiment
The utility model is arranged on the mould bases, the transmission device, the drive unit that comprise upper punch 6 and its motion of drive, be arranged on the floating die and the drive unit that makes its motion of upper punch 6 belows, be arranged on the block 5 of its motion of former lower limit, also be provided with control upper punch 6 and former on the mould bases and suppress the synchronous pressing stroke mechanism 2 of impulse stroke and the block guiding mechanism of control block position synchronously, the utility model makes the drive unit of former motion adopt synchronous oil pressure actuated.
The course of work of the present utility model is: motor passes to power and motion on the crank 1 by power drive mechanism, crank 1 drives upper punch 6 and makes rectilinear motion up and down reciprocatingly, the upper punch 6 that is loaded on the mould bases moves by the track of setting on the machine, move behind the segment distance, upper punch 6 enters cavity impression, formation is to the compacting first time of powder, and it is big that this road compacting forms goods top density.When upper punch continues descending, synchronous compacting bar 3 is contacted with compaction piston bar 4, oil cylinder 7 cavity of resorption volumes are reduced, form a descending power, this journey upper punch 6 and oil cylinder 7 drive central axis component together and move downward, and then realize that former is descending with upper punch 6, in order to guarantee quality of item, the utility model is provided with the synchronous pressing stroke guiding mechanism 2 that makes upper punch 6 and former keep the descending and Bottom Runby of synchronizing speed, to finish the compacting second time according to actual needs, goods bottom density is increased to goods; Then to utilize block 5 that descending former is stopped descending for the utility model, and that upper punch 6 continues is descending, thereby form the compacting for the third time to goods, the intermediate density of the goods of compacting raising this time.Thereby make the goods of suppressing out by the utility model have good density uniformity, be highly suitable for the compacting of article shape complexity.
