Abstract
The utility model relates to a two devices on mould base of powder forming hydropress which includes a cylinder fixed below an upper temperate; the innovation points of the two devices on mould base of powder forming hydropress are as follows: a piston rod is arranged inside the cylinder; the top end of the piston rod is connected with an inner punch; a floating piston forming a closed cavity with the cylinder is sleeved outside the cylinder; and the top ends of the floating piston and the cylinder are respectively connected with an outer punch and a fixed punch. The two devices on mould base of powder forming hydropress has the advantages that: the inside and the outside of the cylinder are respectively provided with the piston rod and the floating piston which can be pushed out; moreover, the punches are connected with the piston rod, the floating piston and the top end of the cylinder; in this way, during pressing, a multi-step metal product can be pressed and formed by one time through the effects of the inner and the outer movable punches and the fixed punch, which does not need machining after pressing, improves the working efficiency and simultaneously avoids material waste.
Description
Technical field
The utility model relates to two devices on a kind of mould bases, two devices on particularly a kind of mould bases that is used for hydraulic press for powder formation.
Background technology
Hydraulic press for powder formation is used for metal dust is pressed into pie or tabular, the hydraulic pressure of traditional hydraulic press for powder formation is taken blame for others and is the one-shot head, it is when many steps of compacting metallic article, at first it is pressed into pie, carry out machining again, production efficiency is low, and the clout after the cutting can't re-use, and causes waste material.
The utility model content
The technical problems to be solved in the utility model provides two devices on a kind of mould bases of hydraulic press for powder formation, can many steps of compression moulding metallic article, and the efficient height has been saved material.
For solving the problems of the technologies described above, the technical solution of the utility model is: two devices on a kind of mould bases of hydraulic press for powder formation, comprise the cylinder body that is fixed on the cope match-plate pattern below, its innovative point is: be provided with piston rod in the described cylinder body, the top of this piston rod is connected with inner punch, described cylinder body is with the floating piston with a near closed hollow ring of its formation outward, and is connected with outer ram and fixing drift respectively on the top of described floating piston and cylinder body.
Further, be provided with limit adjusting mechanism between described piston rod and the cylinder body, it comprises fixing oblique template, movable tiltedly template, adjusting screw(rod), guide spiro rod and gathering sill, its concrete structure is: fixing oblique template is fixed on the bottom of piston rod, between fixing oblique template and cylinder base, be provided with the movable tiltedly template that is mated, the cylinder body sidepiece is connected with the adjusting screw(rod) that the oblique template of promotion activity moves along fixing oblique template inclined-plane, and is respectively equipped with guide spiro rod and along the gathering sill of adjusting screw(rod) pushing direction on described fixing oblique template and movable tiltedly template.
Further, described cylinder body also is with the adjusting nut that blocks floating piston outward, and described adjusting nut and cylinder body adopt the screw thread cunning to join to be connected.
Advantage of the present utility model is: be respectively equipped with the piston rod and the floating piston that can eject inside and outside the cylinder body, and on piston rod, floating piston and cylinder body top, be connected with drift, like this when compacting, can be by the inner and outer movable drift and fixedly under the effect of drift, can many steps of compression moulding metallic article, the waste of material has been avoided in machined again after need not to suppress when increasing work efficiency.
Adjusting nut between governor motion between cylinder body and the piston rod and cylinder body and the floating piston can conveniently be finely tuned the length that ejects of interior outer ram shaping position and floating piston.
Description of drawings
Accompanying drawing is the structural representation of two devices on the mould bases of hydraulic press for powder formation of the present utility model.
The specific embodiment
As shown in drawings, comprise cylinder body 1, piston rod 2, floating piston 3, rebound 4, guide post 5, fixing oblique template 6, movable tiltedly template 7, adjusting screw(rod) 8, guide spiro rod 9, gathering sill 10, adjusting nut 11.
Above-mentioned cylinder body 1 is fixed on the cope match-plate pattern below of hydraulic press for powder formation, be provided with piston rod 2 in its cylinder body, inner punch is equipped with on its top, the outer surface of described cylinder body 1 is stepped, its outer floating piston 3 that is with, form the die cavity of a sealing between the outer wall of this floating piston 3 and cylinder body 1, and on floating piston 3, have the import and export that are communicated with this die cavity.Floating piston 3 is connected with hydraulic system or baric systerm with the die cavity that piston rod 2 and cylinder body 1 form respectively, makes floating piston 3 and piston rod 2 independently eject action.The end of described floating piston 3 is connected with rebound 4, be connected with outer ram on this rebound 4, the top of cylinder body 1 is connected with fixedly drift, and is provided with two guide posts 5 that stretch in the rebound 4 on the cylinder body 1 of the first side of fixed punch, and its outer ram at floating piston 3 play the guiding role when ejecting.
Internally the outer ram shaping position carries out for convenience, between piston rod 2 and cylinder body 1, be provided with governor motion, it comprises fixing oblique template 6, movable tiltedly template 7, adjusting screw(rod) 8, guide spiro rod 9 and gathering sill 10, its concrete structure is: fixing oblique template 6 respectively has an inclined-plane that the gradient is identical with movable inclined plate 7, two inclined-planes are in contact with one another, wherein, fixing oblique template 6 is fixed on the bottom of piston rod 2, movable tiltedly template 7 is located between fixing oblique template 6 and cylinder body 1 bottom, cylinder body 1 sidepiece is connected with the adjusting screw(rod) 8 that the oblique template 7 of promotion activity moves along fixing oblique template 6 inclined-planes, simultaneously, on fixing oblique template 6, have, be fixed with the guide spiro rod 9 that stretches into gathering sill 10 on the movable oblique template 7 along the gathering sill 10 of adjusting screw(rod) 8 pushing directions.
The ejection stroke fine setting of floating piston 3 realizes by adjusting nut 11, this adjusting nut 11 is enclosed within on the outer wall of notch cuttype cylinder body 1, join with its screw thread cunning and to be connected, simultaneously, the other end card master floating piston 3 of adjusting nut 11, like this, by rotation adjusting nut 11, can change the stroke of floating piston 3.
During use, the outer ram of the inner punch of piston rod 2, floating piston 3 is by punching press downwards under the independent effect of piston rod 2 and floating piston 3, at interior outer ram and be fixed under the effect of fixed punch on the cylinder body 1 and can once suppress many steps metallic article, need not to carry out again machined, improved operating efficiency.
