Abstract
The utility model is related to a kind of powder hydraulic press release protection mechanism, it is characterised in that：Including former, Xia Yichong, following two punch, Xia Sanchong, plug, fixed plate, negative template and lower float plate；Negative template is located at the top of fixed plate, and the through hole for accommodating following two punch, lower three punchings and plug is provided with the middle of fixed plate；The object of small shape makes lower float plate drive fixed plate displacement by outer Driven by Hydraulic Cylinder when the demoulding, so as to drive next the rushing at being connected in fixed plate to apply a micro-pressure；So that the object of small shape is not susceptible to fracture when former is drop-down in the demoulding；Product quality of the small article part in the demoulding is improve, defect rate is reduced.
Description
Technical field
The utility model is related to powder Hydraulic Field, more particularly to a kind of powder hydraulic press release protection mechanism.
Background technology
Powder metallurgy is to produce metal or use metal dust（Or the mixture of metal dust and non-metal powder）As original
Material, again by sintering, manufacture metal material, the technique skill of compound and all kinds product after having pressure or shaping without pressure
Art.PM technique possesses that notable energy-conservation, material saving, excellent performance, Product Precision be high and the series of advantages such as good stability, non-
It is very suitable for producing in enormous quantities.At present, PM technique has been widely used in traffic, machinery, electronics, Aero-Space, soldier
The fields such as device, biology, new energy, information and nuclear industry, as most one of branch of development vitality in new material science.With
Domestic powder technology is developed rapidly, and many metal materials use powder compacting technology, i.e., by powder shaping press by gold
Category powder is pressed into pie, then metallic article is obtained by sintering.
The general object for small shape, by after powder hydraulic forming, is direct drop-down negative template in the demoulding,
So that product spills former, but operation causes that object easily causes the edge of the object of small shape when pressure is removed suddenly
The situation for occurring integrally to drop in fracture or edge occurs, and causes defect rate very high.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of powder hydraulic press release protection mechanism, ensure that powder
The situation reduction of the object of the small shape of last stamped metal edge fracture in the demoulding, reduction in the numbers of seconds improves the matter of product
Amount.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of powder hydraulic press release protection mechanism,
Its innovative point is：Including former, Xia Yichong, following two punch, Xia Sanchong, plug, fixed plate, negative template and lower float plate；Former
Plate is located at the top of fixed plate, and the through hole for accommodating following two punch, lower three punchings and plug is provided with the middle of fixed plate；
Former, Xia Yichong, following two punch, lower three punchings and plug are disposed with the negative template from outside to inside；Under described
The bottom of one punching is connected with next punching, and next punching is located between negative template and fixed plate and the bottom of next punching is connected to
In fixed plate；The following two punch, Xia Sanchong are connected to following two punch plate and lower three punching, and following two punch plate is located at lower three punching
Through hole in the vertical direction in the through hole of fixed plate and along fixed plate is moved；The bottom of the plug is driven by a central cylinder
Plug passes through the centers of lower three punchings.
Further, the bottom of the fixed plate is connected in lower float plate, and the bottom of lower float plate is connected with outer hydraulic pressure
Cylinder；The dynamic fixed plate movement of floating strip under outer Driven by Hydraulic Cylinder, so as to drive next punching in the vertical direction displacement.
The utility model has the advantage of：1）The object of small shape makes lower float plate by outer hydraulic cylinder when the demoulding
Drive and drive fixed plate displacement, so as to drive next the rushing at being connected in fixed plate to apply a micro-pressure；So that small shape
Object be not susceptible to when in the demoulding, former is drop-down fracture；Product quality of the small article part in the demoulding is improve, is reduced
Defect rate.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of powder hydraulic press release protection mechanism of the present utility model.
Fig. 2 is a kind of powder hydraulic press release protection mechanism Local map of the present utility model.
Specific embodiment
The following examples can make professional and technical personnel that the utility model is more fully understood, but therefore will not

Accommodate the through hole of following two punch 3, lower three punchings 4 and plug 5.
Former 1, next punching 2, following two punch 3, lower three punching 4 and plug 5 are disposed with negative template 7 from outside to inside；It is described
The bottom of next punching 2 is connected with next punching 21, and next punching 21 is located between negative template 7 and fixed plate 6 and next punching 21
Bottom be connected in fixed plate 6；The following two punch 3, lower three punching 4 are connected to following two punch plate 31 and lower three punching 41, under
The through hole in the vertical direction that two punchings 31 are located in the through hole of fixed plate 6 and along fixed plate 6 with lower three punching 41 is moved；Institute
The bottom for stating plug 5 drives plug through the center of lower three punchings 4 by a central cylinder.
The bottom of fixed plate 6 is connected in lower float plate 8, and the bottom of lower float plate 8 is connected with outer hydraulic cylinder；Outer hydraulic cylinder
The dynamic fixed plate movement of lower floating strip is driven, so as to drive 2 plate in the vertical direction displacements of next punching.
It should be understood by those skilled in the art that, the utility model is not restricted to the described embodiments, above-described embodiment and
Principle of the present utility model simply is illustrated described in specification, on the premise of the utility model spirit and scope are not departed from,
