Both sides 1 positioning hole of each jig bore (interpolation pin), the on the vertical plane each jig bore in both sides 1
Fixing hole (with fixed plate and another module of mode connects for screw)；
(3) type face, is rough milled：Digital control processing type face, 0.8mm~1.0mm surpluses are stayed per face, are fallen
Sharp side, deburring；
(4), it is heat-treated：Rough machined blank is heat-treated, 1070 DEG C of heating-up temperature, protected
Temperature 3~4 hours；
(5), preweld cleaning type face：Use acetone degreasing；
(6), argon arc welding：The hardfacing alloy Co60Cr30W5Si2 at the R switchings in type face, by two
Secondary built-up welding, thickness reaches 1.5-1.0mm, and weldering front module preheats 300 DEG C -400 DEG C, is incubated 30min,
In weld deposit process, in each heap postwelding, solder surface is beaten with hand hammer, cooling is melted down；
(7) it is, extraordinary to examine：Defect at dyeing inspection built-up welding；
(8), finishing drum face：First, at the R switchings of finish-milling type face and at crowded bar, 0.02 is stayed per face
At mm-0.03mm, then electric pulse finishing pier nose, 0.02mm surpluses are stayed per face；
(9) it is, extraordinary to examine：Defect at dyeing inspection built-up welding；
(10), refine type face：Type face is repaired, holotype is polished, the sharp side in non-processing face is fallen
Angle, deburring；
(11) it is, extraordinary to examine：Three coordinate measurement working surfaces；
(12) outline, is processed：There is no each processing one on the face of coordinate bore hole in two modules
Fitting surface, 0.1mm-0.2mm surpluses, fine grinding fitting surface to finish forge are stayed per face.
The material of described module is 4Cr5W2VSi.
Described fitting surface is 10 DEG C.
The present invention has the advantage that and beneficial effect, the present invention using the built-up welding at the R of type face method,
Make wearability increase of the extrusion die at the R of type face, so as to add the mold use life-span, use
Life-span is 2-3 times of normal mould.Mould is convenient to use, without liftout attachment, extrusion
Just it can be removed from the molds.Die manufacturing cost is low, and a set of frock only has former, 2 moulds of drift
Block, a set of frock can save nearly 0.5 ten thousand yuan of manufacturing expense.With mould pressure resistance produced by the present invention
Degree is big, dimensional accuracy is high, wear-resisting, the manufacturing cycle is short, low cost, directly squeezes pre- forging stock than normal
Shaping (squeezing bar, heading, blocking, trimming) method saves 3 sets of frock, shortens grinding for blade
Cycle processed.
