Silicon and satisfaction casting require.
Wherein, step 201 may include: to press in an end face of alloy cast ingot, and alloy cast ingot is struck out plate structure.
As shown in figure 3, copper-nickel alloy ingot casting 1 can be machined to 400 DEG C to 600 DEG C, and corronil is cast when realizing
Ingot 1, which is placed on press machine workbench, controls hot upsetting tooling 2 to 1 punching press of copper-nickel alloy ingot casting, hot under the action of press machine
Copper-nickel alloy ingot casting 1 is beaten in the continuous upsetting of upsetting tooling 2, is gradually increased the cross section of copper-nickel alloy ingot casting 1, to obtain plate workpiece.
Wherein plate workpiece has the outside wall surface of opposite two planes of two planes and connection.
Step 202: stamping out centre bore along the direction perpendicular to plate workpiece at the geometric center of plate workpiece.
As shown in figure 4, step 202 may include: that plate workpiece 11 is machined to 400 DEG C to 600 DEG C, it is then placed within
It is aligned at the geometric center of plate workpiece 11 on press machine workbench using punch workpiece 3, along the side perpendicular to plate workpiece
To pressure, centre bore 5 is stamped out.
Step 203: reaming processing is carried out to centre bore.
As shown in figure 5, plate workpiece 11 is machined to 400 DEG C to 600 DEG C, and reaming thick stick 4 is passed through into centre bore 5, control
Reaming thick stick 4 persistently rotates, and increases the hole size of centre bore 5 constantly, is machined to be sized, by preliminary to centre bore 5
It is expanding, facilitate it is subsequent by plate workpiece 11 processing circlewise.
Step 204: the outside wall surface of hole wall and plate workpiece to centre bore carries out heat and grinds processing.
Step 204 may include: the outside wall surface of the hole wall and plate workpiece 11 using Roller Machining centre bore 5.
As shown in fig. 6, realize when, plate workpiece 11 can be machined to 400 DEG C to 600 DEG C, centre bore 5 hole wall and
A rotating roller 6 is respectively set in the outside wall surface of plate workpiece 11, then plate workpiece 11 is placed on ring rolls, control turns
The dynamic rotation of roller 6 is ground the hole wall of centre bore 5 and the outside wall surface of plate workpiece 11, is cast respectively to alloy by two rotating rollers 6
Inner wall and outside wall surface the progress heat of ingot, which are milled, cuts, so that the wall thickness of alloy cast ingot reduces.
Wherein, before the axially cutting formation Cutting Road along annular work piece, Roller Machining plate workpiece can also be used
11 two planes.
As shown in fig. 6, a roll 7 is respectively set in two planes of plate workpiece, the control rotation of roll 7 is to plate
Two flat surface grindings of workpiece, obtain annular work piece 12.
Step 205: along the axially cutting formation Cutting Road of annular work piece, annular work piece being unfolded from Cutting Road.
Wherein, step 205 may include: that the axial direction by any position of annular work piece 12 along annular work piece 12 is cut
It cuts, and annular work piece 12 is unfolded at Cutting Road using hammer anvil on press machine, be launched into the inner wall of annular work piece 12
Plane.
During using the inner wall of press machine expansion annular work piece 12, controlling to push every time makes annular work piece 12
Thickness reduction is within 15mm.
Step 206: cold-heading processing being carried out to the annular work piece after expansion, obtains alloy sheets.
Step 206 may include: to carry out 4~6 cold-headings to annular work piece, and each cold-heading reduces the thickness of annular work piece
H, 0mm < H≤10mm.

Thickness reduce 10mm so that annular work piece 12 reaches specified thickness.The method of cold-heading can guarantee alloy cast ingot in this way
Material is flowed in the length direction of plate-like alloy cast ingot, guarantees the uniformity of alloy cast ingot material, to improve alloy cast ingot
Strength character.Such header system is cracked during can also being effectively prevented simultaneously.
It also needs that the annular work piece 12 after expansion is made to meet straightness requirement, detailed process after cold-heading through the above way
It may include: that 2~4 cold-headings are carried out to annular work piece, each cold-heading makes the thickness of annular work piece reduce h, 0mm < h≤10mm.
As shown in fig. 7, can control the surface that cold-heading tooling 8 is pressed in annular work piece 12 by press machine, from ring-type when realizing
The middle position of workpiece 12 can repeat pressure cold-heading 3 times to successively pressing cold-heading to the surface of annular work piece 12 at two sides,
Pressure makes the thickness of annular work piece 12 reduce 5mm every time, so that annular work piece 12 meets straightness requirement.It is applied every time by control
Pressure make annular work piece 12 thickness reduce 5mm, it is ensured that the straightness of the annular work piece 12 after expansion within 5mm, thus
The alignment of annular work piece 12 after realizing expansion, the annular work piece 12 after making expansion reaches the straightness of requirement, to obtain alloy
Plate.It is cracked during can also being equally effectively prevented.
In order to ensure not cracked after cold-heading, can be detected by the method for flaw detection whether there is crackle in alloy sheets.
If detecting in alloy sheets there is no crackle, show that the processing quality of alloy sheets is qualified, which is that qualified product can carry out
Further processing；If detecting in alloy sheets there are crackle, shows that the processing quality of alloy sheets is unqualified, need alloy sheets
Refuse in furnace is set, alloy cast ingot is made and is reprocessed into alloy sheets.
Step 207: aging strengthening model is carried out to the alloy sheets after expansion.
Step 207 may include: control aging heat treatment temperature within 500 DEG C, carry out at timeliness heat to alloy sheets
Reason corronil hardening constituent is precipitated, and eliminates the internal stress generated during cold-heading.
The foregoing is merely a prefered embodiment of the invention, is not intended to limit the invention, all in the spirit and principles in the present invention
Within, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
