Description
Technical field
The present invention relates to welding technology field, more particularly to a kind of part deposition frock and method.
Background technology
Existing part deposition techniques method has two kinds：The remelting of oxygen acetylene flame jet soldering and vacuum drying oven.Both effects
Identical, final purpose is all to harden piece surface, reaches resistance to erosion, corrosion-resistant, wear-resistant and resistance to oxidation purpose.Before
Deposition of the person mainly for below DN100 single-pieces, small lot core or valve seat；The latter is for high-volume, heavy caliber part
Deposition.Both common ground are to be required for being sprayed, and spraying method at this stage is all the mode using hand spray powder
Carry out, its shortcoming is：The waste of powder is big, spraying cost is high, heavy parts coating thickness hardly possible controls, hand labor intensity is big,
It is big to human injury.
Existing spray equipment mainly has pistol, powder dust feeder, oxygen-acetylene gas cylinder and a part clamping
Lathe.In our current deposition techniques, spraying process is all that part is held on lathe, and man-hour manually hand-held spray gun is sprayed
Apply.First will dust 0.1~0.3mm in advance in spraying process, then step up workpiece temperature (500 DEG C or so), then spray work
Layer powder namely dusts, and uniformly to be sprayed during dusting, and gross thickness is usually no more than 1.2mm, such as needs thicker spray
Coating, it can be dusted again to required thickness after remelting.Neutral flame should be used to spray when dusting, and Workpiece painting temperature should not
Less than 350 DEG C.So whole spray coating process is harsher to labor claim, it is necessary to which high-level welder carries out spraying ability
The effect reached, and powder sprinkling wastes seriously, and worker's spraying labor intensity is big, and difficulty is high, the security of oxygen-acetylene
There is also hidden danger in management.There is also above-mentioned technical problem for the deposition apparatus patent of the patent No. 93100861.1.
The content of the invention
The technical problem to be solved in the present invention is：In order to which the waste of powder in the prior art is big, spraying cost is high, large-scale by zero
The difficult control of part coating thickness, hand labor intensity is big and the technical problem big to human injury, the present invention provide a kind of part
Deposition frock and method.
The technical solution adopted for the present invention to solve the technical problems is：A kind of part deposition frock, for deposition core
Outer surface, core includes spheroid and positioned at the left runner hole of spheroid both sides and right runner hole, and left runner hole and right runner hole are closed
In the Central Symmetry of spheroid, the line of left runner hole center, right runner hole center and ball centre excessively is straight line L, crosses straight line L's
Core is divided into top half and the latter half by any one plane, and the part deposition frock is included in the frock that coordinates up and down
Lid and frock lower cover, have upper impression in frock in lid, the shape outside the shape of the upper impression and the top half of core
Unanimously, and the top half of core can be accommodated, is covered in frock and be additionally provided with discharge groove, one end of upper discharge groove and upper impression
Connection, the other end of upper discharge groove extend to the lateral surface covered in frock, have lower impressions in frock lower cover, the lower impressions
Shape is consistent with the shape outside the latter half of core, and can accommodate the latter half of core, is additionally provided with frock on lid
Lower discharge groove, one end of lower discharge groove connect with lower impressions, and the other end of lower discharge groove extends to the lateral surface of frock lower cover, on
Die cavity and lower impressions are symmetrical, in frock after lid and frock lower cover split, upper discharge groove and lower discharge groove can split it is in a row
Expect hole.Part deposition frock of the present invention can make the utilization rate of powder reach 100%, and labour cost and the work for reducing worker are strong
Degree, shorten spray time, accelerate the efficiency of deposition, shorten the whole production cycle.And then deposition cost is saved comprehensively, improve life
Produce efficiency.
The volume of the upper impression is more than the volume of the top half of core, and the volume of lower impressions is more than the lower half of core
The volume divided.It can so to leave certain interval between the die cavity of core and deposition frock, for controlling coating layer thickness.
In order to improve heat resistance, covered in the frock and frock lower cover uses graphite.
A kind of part cladding method, using part deposition frock described above, there are following steps：
1) dusty spray is made to the soldering paste of paste, is applied to the outer surface of the core by pretreatment, smearing thickness is
Below 3mm (is formulated) according to accessory size；
2) core in step 1) is put into described part deposition frock, by being covered on upper and lower external force extrusion tooling and
Frock lower cover is mutually close to so that the soldering paste thickness in part deposition frock is distributed evenly in core outer surface, unnecessary weldering
Cream is discharged after being extruded from relief hole；
3) remelting is carried out again.
The invention has the advantages that the part deposition frock and method of the present invention, by changing spraying method, can drop
The waste at self raising flour end, the utilization rate of powder is improved comprehensively, worker's labour cost and labor intensity is reduced, removes oxygen, acetylene gas from
The use of body, the cost sprayed in deposition techniques, and uniform coating thickness are saved comprehensively.
