Description
Technical field
The present invention relates to a kind of pouring technologies, and in particular to a kind of cast new process of sliding bearing babbit-lined metal.
Background technology
Currently, the country mostly uses centrifugally cast mode, technics comparing is complicated, and equipment is complicated, can be caused centainly to alloy
Waste, lead to the reduced performance of babbit itself, easy to produce segregation, the defects of de- Sales, Electricity are split, bubble.In addition, Pasteur
Bearing shell service life of the alloy casting on surface is generally shorter, and the shortest service life, the longest service life was also no more than two at 45 minutes or so
Year.Large-scale babbit shell casting generally use sand mold gravitational casting, during cast, molten metal be also easy to produce splashing,
Oxidation, volume gas, the defects of leading to casting generation stomata, be mingled with so that cast(ing) surface quality, mechanical property are all undesirable.Low pressure
To fill, type is steady, speed is easily controllable, casting compactness and the advantages that high mechanical properties are taken seriously for casting.Although this technique is protected
Stable Filling from bottom to top and Under Pressure Solidification have been demonstrate,proved, but cannot be guaranteed the consecutive solidification of casting, ingate, sprue.Reason
Require sprue and gap running channel that should be slower than the cooling of shell on, but in production, when gap running channel is wide or narrow,
It will influence the assembling of shell, the defects of causing casting draw or insufficient feeding.
Invention content
The object of the present invention is to provide a kind of cast new processes of sliding bearing babbit-lined metal, and operation is simpler, system
Make superior bearing shell.
In order to achieve the above objectives, technical solution provided by the invention is：
The cast new process of sliding bearing babbit-lined metal, includes the following steps：
A. bearing shell heat treatment and cooling treatment are carried out first, and bearing shell is put and is heated to 400 degrees Celsius in heating furnace, then
5 to 6 hours are kept the temperature after being heated to 700 degrees Celsius；Bearing shell is taken out out of heating furnace with iron clamp, is cooled to room temperature；
B. polishing inside bearing shell is removed into oxide layer with sander, cleans bearing shell with saturation liquor zinci chloridi after polishing, i.e.,
Saturation liquor zinci chloridi is filled inside cast iron；
C. bearing shell is placed on mold one, the tin liquor melted is poured on bearing shell, while being quickly pressed in mold two
It is placed on the bearing shell of tin liquor, after placing 2 minutes, removes mold two；
D. the bearing shell for hanging up properly tin is put in heating furnace, temperature is set as 100 degrees Celsius, it is Celsius that bearing shell is heated to 100
After degree, 10 minutes are kept the temperature；
E. it uses chloride dehydrate ammonium to smear bearing shell, carries out refining treatment in heating furnace；
F. bearing shell is taken out with iron clamp out of heating furnace, is placed on mold one, the babbit liquid melted is quick
It is poured on preheated bearing shell, while quickly preheated mold two being pressed on the bearing shell for being placed with babbit, place 2 minutes
Afterwards, mold two is removed；
G. after the bearing shell after to be cast is cooled to room temperature, bearing shell is removed from mold one, completes cast.
Wherein, in step c, first block tin is placed in melting furnace, temperature-controlled cabinet is set as 500 degrees Celsius, heating 73
After minute, block tin fusing, tin liquor temperature is 400 degrees Celsius at this time；Stainless steel strainer is used to remove the impurity in tin liquor again.
In step c, bearing shell is all put into tin liquor.
In step f, first babbit is placed in melting furnace, temperature-controlled cabinet is set as 600 degrees Celsius, heats 90 points
Zhong Hou, babbit melt, at this time 450 degrees Celsius of fluid temperature；Slag in babbit liquid is removed with stainless steel strainer again
It goes.
In step f, mold two is put and is preheated in heating furnace, temperature setting is 200 degrees Celsius, and mold two is heated
20 minutes are kept the temperature after to 200 degrees Celsius.
The mold one includes horizontal base, supporting rack, front apron, rear baffle and wedge plate, supporting rack peace
Mounted in four angles of pedestal bottom surface, the side of the pedestal is equipped with vertical rear baffle, and the rear baffle is fixedly mounted, after
Baffle prevents the molten metal of cast from overflowing for fixing bearing shell.
The rear baffle opposite is equipped with vertical front apron, and front apron prevents the metal of cast for fixing bearing shell
Hydrorrhea goes out, and is equipped with sliding slot on the surface of one pedestal of mold, the slide plate of the front apron bottom is fastened in sliding slot, and front apron can edge
Sliding slot is moved forward and backward.
The both sides of baffle and front apron are equipped with wedge plate in the rear, and the wedge plate tilts outward.In front apron and
Pedestal between rear baffle is equipped with slot, and the bearing shell bottom end is equipped with plunger, and the plunger can be inserted into slot.
The mold two includes spheroid shape die ontology, and fixed iron piece, stent are equipped in die ontology left and right ends
Tool, prevents mold two from being slided during pushing, while the two iron plates also prevent mold two from pushing process axis
The babbit of watt inside overflows.
It is that the iron staff of bearing shell lower end is inserted into the slot of one upper surface of mold by the correct way that bearing shell is placed on mold one
Interior, iron staff is inserted into slot, and bearing shell is stablized and is fixed, and ensures that bearing shell is horizontal positioned.
Since there are error, the temperature height of typical temperature display screen display with the temperature in furnace body for heating furnace setting temperature
In the temperature in stove, so when reaching setting temperature on temperature display, it is also necessary to keep the temperature a period of time again.
When placing mold two, since molten metal cooling is very fast, it is ensured that speed is fast.Place mold two when
It waits, to stablize placement, prevent metal liquid from pushing moment spilling.
The extruding pouring technology of the present invention is different from traditional handicraft, and operation is simpler, and making is more superior, and has made a set of
Completely new mold.
Matrix is first heat-treated and cooling treatment by the present invention, and polishing is except oxide layer and cleans bearing shell, after having handled
It carries out tining processing to be all put into bearing shell in tin liquor in processing procedure, to reach better effect.Using ammonium chloride and
Chlorination zincon plays the role of anti-oxidation and cured.Finally carry out babbit extruding cast, by babbit liquid fall in
In bearing shell, extrusion process is carried out using mold, obtains superior babbit-lined metal finished product.
The shortcomings that overcoming the prior art by pouring technology of the present invention completely fills the premise of type in guarantee babbit liquid
Under, temperature is suitably reduced, to reduce babbit shrinkage, casting solution low speed rises liquid, Stable Filling, Quick-pressurizing, extension
Dwell time can avoid cast gate distal end and the defects of shrinkage porosite occur, improve casting compactness, produce superior bearing shell, for industry
New direction is directed toward in the production of bearing shell, is made for industrial bearing shell and is saved a large amount of financial resources, manpower, has prodigious social economy effect
Preferably.
