Graphics on calibrate molding all sizes.
Process 2, die sinking：According to the 3D models of the connector established in process 1, open up and the corresponding mould of stainless joint
Tool, the 3D models of stainless joint are imported into CAM softwares, connector can be processed by CAM Software Creates machine tool
NC codes, then the NC codes of generation are imported on machining center, while mould steel is placed in fixed bit in machining center
To put and determine machining benchmark, machining center completes process route and cutting tool path according to the instruction of importing on mould steel,
The shaping mold cavity of stainless joint is precisely formed on mould steel, it is ensured that the cavity finish of mould reaches technological requirement.
Process 3, die cast：The raw material powder die casting of stainless joint is entered into mould molding using Special forming machine, is made
Into semi-finished product, the material of stainless joint is 316 powder of stainless steel, and mould is installed on Special forming machine, 316 stainless steel powders
End is added in the rewinding chamber of Special forming machine, and the injection mechanism of Special forming machine is by 316 powder of stainless steel under high-voltage high-speed
For extrusion packing in mold cavity, 316 powder of stainless steel form the semi-finished product of stainless joint under high pressure.Due to pressure casting method
Producing product has production efficiency high, and process is simple, and Casting tolerance is higher ranked, and surface roughness is good, and mechanical strength is big, so
Substantial amounts of machining operation and equipment can be saved, is saved material, and die cast is cracked with casting than less likely
It caused may explode, reduce danger.
Process 4, sintering：The semi-finished product of stainless joint are placed under vacuum environment, temperature is maintained at 1300 DEG C -1350
DEG C, sinter 15 hours；When natural cooling 12 is small under vacuum conditions, taken after the semi-finished product shaping of stainless joint from mould
Go out, the semi-finished product of stainless joint are transferred in box type vacuum electric furnace afterwards, the inner air extraction shape of box type vacuum electric furnace
Into vacuum, while the temperature control of box type vacuum electric furnace persistently sinters the semi-finished product of stainless joint at 1300 DEG C -1350 DEG C
15 hours, box type vacuum electric furnace, which is cut off the power, afterwards stops heating, and the inner vacuum environment of box type vacuum electric furnace gradually cools down,
The semi-finished product of stainless joint do not take out in cooling procedure, to be cooled down with the inner vacuum naturally of box type vacuum electric furnace
12 it is small when.
Process 5, post processing：In order to improve the performance of product, finish etc., magnetic grinding processing, stainless joint are carried out
Taken out after heat treatment process from box type vacuum electric furnace, stainless joint by the finish of heat treatment process rear surface not
The required value set in technique can be reached, stainless joint is due to being molded by being machined, the frame of stainless joint
For transition position there is sharp corner, this can cause stress concentration, and stainless joint load pressure produces fatigue crack compared with conference,
The service life of stainless joint is affected, so stainless joint will carry out magnetic grinding processing to eliminate residual defects, will
Stainless joint is put into Magnetic Force Mill, is conducted to stainless pin, card grinding, mill material, driven stainless by the strength in magnetic field
Steel connector high-frequency rotational flow, vibration, commutation rolling, stainless pin, card grinding, mill material phase mutual friction stainless joint surface,
Endoporus, inside and outside tooth, reach the precise polished effects such as cleaning, rounding sharp end, lapped face, improve the machinery of stainless joint
Performance.
Process 6, finished product, stainless joint reach technological requirement by 5 rear surface finish of process, are transferred to detection at this time
In process, become finished product by determining qualification after various cubings, measurer detection and transporting storage.
The integral forming process of stainless joint only needs six procedures to produce shaping, so that processing stainless steel connects
The whole process of head is easier, and the waste material of mechanical processing generation can be eliminated by 3D modeling and die cast process, but also
The production time is shortened, improves production efficiency and yield, since controllability of the 3D modeling on shape of product is very high, so production
The complex model of product also can be controlled accurately, molding product design uniformity higher.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to the structure of the present invention
Think and scope is defined.On the premise of design concept of the present invention is not departed from, technology of the ordinary people in the field to the present invention
