Specific embodiment
Specific embodiment 1: illustrating present embodiment below with reference to Fig. 3.Present embodiment the following steps are included:
One, the partial size 5mm alloying pellet 1 below generated in nodularization alloy block production process is collected；Two, the alloy that will be collected into
Grain 1 is fitted into the compression mold cavities 2 of mechanical press, and the press mold chamber 2 is cylindric；Three, the pushing formed punch 3 of mechanical press is in liquid
It presses downwards under the action of pressure, the alloying pellet 1 in compression mold cavities 2 is pressed into cake；Four, the pushing formed punch of mechanical press
3 lift, and for closing the mechanical press low punch 4 of 2 bottom surface of compression mold cavities uplink under the action of hydraulic coupling, press into closing
In die cavity 2, the cake that alloying pellet is pressed into ejects compression mold cavities, completes demoulding.
In general, the constituent of Antaciron nodulizer is Mg:2-10%, RE:0-4%, Ca:0.3-3%, Al:
1.0% hereinafter, Si:36-48%, Fe are surplus.
The chemical component in present embodiment in Antaciron nodulizer is given in the following table 1:
Table 1
The mechanical press parameter used is as follows:
Table 2
Through overtesting, die size has been selected, has completed demoulding and pressure Adjustment Tests, used mechanical press is shown in
The finished product of Fig. 1, preparation are shown in Fig. 2.The blocking requirement of pressure can be basically reached.
Specific embodiment 2: illustrating present embodiment below with reference to Fig. 3 and Fig. 4.Present embodiment is in embodiment party
Increase the operation to the alloying pellet water flushing and heating, drying that are collected on the basis of formula one in the first step.It is other with it is real
It is identical to apply mode one.
Specific embodiment 3: illustrating present embodiment below with reference to Fig. 3 and Fig. 4.Present embodiment is in embodiment party
Increase following operation on the basis of formula one in step 2: the alloying pellet being collected into being fitted into alloy shell 5, the alloy
Shell 5 is round pie, and the alloying pellet top in alloy shell 5 adds the lid 6 of a disc-shaped, the outer diameter and alloy shell 5 of lid 6
Internal diameter it is identical or smaller, the upper surface of lid 6 is concordant with the top edge of alloy shell 5；Then alloy shell 5 is placed
Into in the compression mold cavities 2 of mechanical press.Gap between the outer diameter of alloy shell 5 and the internal diameter of compression mold cavities 2 be 1 to 2 millimeter it
Between.Ingredient identical with alloying pellet can be used in 5 material of alloy shell.The material of certain alloy shell 5 is in order to mention
High-ductility can also select the ingredient different from alloying pellet, such as Al, as long as not conflicting with the function of nodulizer, and can lead to
Cross a part after conversion scale ingredient as nodulizer ingredient be subject to using can, be that ordinary people in the field may be used herein
With the selection made, no longer it is described in detail.
So set, during the pushing formed punch 3 of mechanical press presses downwards, it is only necessary to the upper of alloy shell 5
It is pressed along with lid 6, required lower pressure greatly reduces.In addition, when loading alloying pellet to alloy shell 5, it can be with
Far from mechanical press, not only convenient for operation, but also the environmental sanitation of protection mechanical press.It is flat that a vibration can also be made simultaneously
Platform loads the alloy shell 5 of alloying pellet in shock platforms, and gap is smaller between the particle of filling.Other and embodiment one
It is identical.
Specific embodiment 4: illustrating present embodiment below with reference to Fig. 4.Present embodiment is in embodiment three
On the basis of specifically limit: the side wall of alloy shell 5 and bottom with a thickness of 0.7 millimeter, lid 6 with a thickness of 0.7 millimeter；Push formed punch
3 lower end surface is provided with circular boss 3-1, and the center line of boss 3-1 is overlapped with the center line for pushing formed punch 3；Boss 3-1's
Outer diameter is corresponding with the internal diameter of alloy shell 5, and four gap 5-1 of up and down direction extension are provided at 5 upper edge of alloy shell, slits
The length of mouth 5-1 is 0.5 millimeter, and gap 5-1 is uniformly distributed in the circumferencial direction of alloy shell 5.
So set, boss 3-1 is pressed against on lid 6, and the outer edge of alloy shell 5 presses against conjunction when pushing the pushing of formed punch 3
On the upper edge of golden shell body 5, while lid 6 pushes, the edge of alloy shell 5 to in-flanges and is pushed, and stablizes alloying pellet
Ground is enclosed in alloy shell 5.
So set, mechanical press exports 1 ton of pressure below, shaping work can be completed, to the pressure of stamping device
Force request is small, and device work is more reliable.It is other identical as embodiment three.
