Description

Dissimilar metal diel increasing material manufacturing method
Technical field
The present invention relates to increases material manufacturing technology field more particularly to a kind of dissimilar metal diel increasing material manufacturing methods.
Background technology
Zinc alloy die is the simple die made of high strength zinc alloy material by the processing methods such as casting or squeezing.Zinc The formation of parts of alloy mold is made of casting or plastic processing method, it saves and add compared with the manufacture of common punching block Work process, and need not be heat-treated.Therefore, have the characteristics that mould making process is simple, the period is short, at low cost.However, kirsite with Common punching block is low compared to intensity, in punching press edge since active force is big, easy tos produce abrasion, service life is shorter.
Increases material manufacturing technology refer to based on discrete-accumulation principle, by software and digital control system by dedicated metal material, Nonmetallic materials and biomaterial for medical purpose are successively accumulated according to modes such as extruding, sintering, melting, photocuring, injections, manufacture Go out the manufacturing technology of physical item.The period that mold manufacturing can be shortened using increases material manufacturing technology, especially for kirsite Mold forms dissimilar materials mold if the method that can use increasing material manufacturing is manufactured into steel construction in edge, then both can be real The existing advantage that Zinc alloy die is at low cost, the period is short, and can effectively improve mold usage time.
However, the fusing point of kirsite only has 400 DEG C or so, the fusing point of steel is but up to 1500 DEG C or so, if directly in zinc Increasing material manufacturing is carried out using the methods of laser, electric arc on alloy, heat source and liquid steel will make zinc liquefy rapidly, gasify, can not Form effective manufacture.How to produce the dissimilar metal mold of kirsite-steel construction becomes current urgent problem to be solved.
Invention content
The problem of dissimilar metal mold increasing material manufacturing hardly possible is formed according to kirsite set forth above and steel, and is provided a kind of different Matter metal stamping die increasing material manufacturing method.Mainly using different increasing material technologies, successively transition method realizes manufacture, mould to the present invention Tool main body is kirsite matrix, and mold is Steel material by the fillet of more impact wear in punching course, and kirsite is made The dissimilar metal diel of matrix-layers of copper-steel rounded structure, to both may be implemented, Zinc alloy die is at low cost, the period is short The advantages of, and can effectively improve die life.
The technological means that the present invention uses is as follows：
A kind of dissimilar metal diel increasing material manufacturing method, which is characterized in that include the following steps：
S1, the diel based on kirsite matrix is produced using casting, the method being machined, justified in its punching press It is not manufactured at angle, reserves the platform of pre-set dimension, it is to be processed；
The fine copper or copper alloy within 2mm are accumulated at S2, the platform prepared in step sl using the method for spraying, are formed The structure of kirsite matrix-layers of copper；
S3, deposition accumulation is carried out on layers of copper surface using laser or electric arc, produces the fundamental form at mould punching fillet Shape forms the structure of local kirsite matrix-layers of copper-steel fillet, and finally being polished by refine according to die size, it is final to be formed Diel.
For the prior art, the present invention has the following advantages：
1, the connection that transition metal realizes kirsite matrix and steel fillet is chosen.Zinc alloy die is at low cost, but the service life It is short；The increasing material manufacturing steel fillet directly on kirsite matrix needs transition zone golden since the eutectic boiling point of kirsite cannot achieve True existing the two combines.
2, the transition metal of fine copper or copper alloy as heterogeneous mold manufacturing is chosen.Brass, i.e. ormolu are industry Upper widely used material, therefore the good knot with kirsite matrix may be implemented as transition metal using fine copper or copper alloy It closes；There is two kinds of metals of copper and steel good metallurgical binding, weld strength can reach copper alloy base material.In summary two Point chooses it as transition metal.
3, spraying process is chosen as copper alloy transition zone preparation process.Since to melt boiling point extremely low for zinc, using current tradition Increasing material manufacturing method (such as the methods of laser, electron beam, electric arc deposited) prepares transition zone, causes zinc a large amount of since heat is excessively high Fusing, gasification, select spraying process that can reduce damage of the heat source to Zinc Matrix to the greatest extent.
4, steel fillet deposition techniques control.Spraying process heat is low, is mechanical bond between copper or copper alloy and Zinc Matrix Or the metallurgical mixing binding pattern of machinery-, while there are stomata, microcosmic interlayer are unbonded in sprayed coating.Using heat such as laser, electric arcs When source carries out steel fillet deposition, parameter request accurately controls, and easily realizes：Metallurgical binding, copper close between copper alloy and Zinc Matrix High intensity connects between defect expressivity, copper alloy and steel fillet in golden transition zone.
The increases material manufacturing technology field that the present invention can be between kirsite and steel based on the above reasons is widely popularized.
