Description

Using the brake disk mounted production method of the wheel of Computer Simulation Software
Technical field
It is especially a kind of the present invention relates to a kind of wheel for taking turns brake disk mounted production method and application this method is brake disk mounted Using the brake disk mounted production method of the wheel of Computer Simulation Software.
Background technique
Currently, the foundation brake of the fast rail train in city, passenger train and train of high-speed motor train unit is all made of disc braking dress It sets, the effect of disc brake is to make the friction of brake lining vertical compression wheel dress or axle-mounted brake disk when vehicle is implemented to brake Face generates frictional force, thus generates braking moment, and the kinetic energy and potential energy when by vehicle movement are thermal energy, so that reaching makes vehicle Slow down or parking purpose.Therefore brake disc is the critical component that train momentum and potential energy are converted to thermal energy by friction.
Publication No. is that the patent of invention of CN102069148A discloses a kind of casting method of brake disc for high-speed locomotive, is wrapped Include following steps: solidification simulation, design sand core, core box production, coremaking, group core, melting casting, shake out knockout and cleaning, the hair It is bright that husky core is designed according to brake disc in such a way that no case folds core combination casting, and brake disc for friction rubbing surface in flat Face setting is taken turns brake disk mounted because of geometry asymmetry, the cooling of radiating surface side although high production efficiency in casting process It is bad, cause inhomogeneous cooling even, casting two sides shrinking percentage is different, therefore the casting produced often generates buckling deformation, shape in batches The rubbing surface of waviness, though casting after deforming makes geometric dimension meet drawing requirement by machining, but due to It is in uneven thickness caused by entire disk body circumferential deformation that dynamic balancing detection can still can not pass through, become can not repair it is useless Product.
Summary of the invention
To overcome above-mentioned problems of the prior art, the present invention provides one kind and is easily achieved, avoids that warpage change occurs The brake disk mounted production method of the wheel of shape, and it is brake disk mounted using the wheel that this method manufactures.
Brake disk mounted production method is taken turns the technical solution of the present invention is as follows: a kind of, in the brake disk mounted casting process of wheel, The radiating ribs top surface of brake disc radiating surface increase a whole cyclic annular gusset (cyclic annular gusset with a thickness of 10mm or 5mm or 6mm or 7mm or 8mm or 9mm), radiating ribs top surface is linked up one by one, the ring-type gusset and brake disc one-step casting Molding forms firm, the bicyclic setting in top and bottom a ring-shaped frame structure, improves the cooling uniformity of casting, prevents from casting Buckling deformation occurs in cooling procedure for part, and the machining allowance top of the rubbing surface of the brake disc is designed to the conical surface, is increased The resistance of casting deformation makes casting that stabilized contraction be kept to be removed the cyclic annular gusset of radiating ribs top surface after the completion of cooling, Plane is processed on the machining allowance top of the rubbing surface of the brake disc.
Another kind takes turns brake disk mounted production method, including step specific as follows:
A, sunykatuib analysis is carried out to the casting technique and casting mould of the brake disc by Computer Simulation Software, determine described in The cyclic annular gusset size of radiating ribs top surface, while the machining allowance top of the rubbing surface of the brake disc is designed to the conical surface, make it Section becomes triangle by rectangle, increases the resistance of casting deformation, so that casting is kept stabilized contraction, prevents from deforming;
B, the casting technique for formulating the brake disc carries out bottom pour mold in such a way that bottom is returned and introduces molten metal, wherein molten metal by Rectification filtering bottom of device enters type chamber;
C, according to the sunykatuib analysis of step A as a result, the machining allowance top of production casting mould, cyclic annular gusset and rubbing surface meets The result of sunykatuib analysis in step A;Wherein, cyclic annular gusset is with a thickness of 10mm or 5mm or 6mm or 7mm or 8mm or 9mm
D, coring processed, mould assembling, melting casting, cooled and solidified, shake out knockout;
E, roughing and heat treatment are carried out to casting, removes the machining allowance top of cyclic annular gusset and rubbing surface;
F, modifier treatment and finishing are carried out to casting.
Before carrying out sunykatuib analysis, needs technical requirements to be achieved to analyze on casting first, simulated according to technical requirements The casting technique and casting mould of brake disc.The simulation softward that the present invention selects includes suitable for Materials Processing Engineering and manufacture neck Any simulation softward in domain, as Magma, ProCast, NovaCast, AnyCast, Flow3D, InteCast CAE, Ansys, Abaqus, Marc etc..
Simulation softward is opened, physical model is established, the grid division on model, setup parameter carries out sunykatuib analysis;According to Then analog result tuning parameter carries out sunykatuib analysis using new parameter again;By continuous tuning parameter, obtaining can Reach the casting technique and casting mould of casting techniques requirement.
The present invention does not increase the premise of technique thermal center by calculating to meet the normal consecutive solidification of casting unaffected Under, it solidifies the cyclic annular gusset of radiating ribs top surface during the cooled and solidified of its casting after pouring first, fixes numerous differences The radiating ribs of shape, so that the defect for reaching the buckling deformation for solving rubbing surface and forming wavy surface, makes the parallel of two anchor rings Degree is completely in technique claimed range, and then the product formation met after machining uniformly rubs ring thickness, completely by dynamic Balance test.
Further, the cyclic annular gusset thickness is no more than 10mm, meets cooling and uniformly requires, reduces the wave of raw material to the greatest extent Take.
A kind of wheel is brake disk mounted, which is made using any of the above-described method.Prepared brake disc is in cooling procedure In shrinking percentage it is obviously uniform, rubbing surface uses taper machining allowance top, increases the resistance of casting deformation, and casting is made to keep steady It is fixed to shrink, buckling deformation is prevented, waveform rubbing surface no longer occurs, and the percent of pass that wheel detects dynamic balancing is substantially improved.
The technical effect of invention: (1) the brake disk mounted production method of wheel of the invention was manufacturing compared with the existing technology Cheng Zhong increases by a whole cyclic annular gusset in the radiating ribs top surface of brake disc radiating surface, and the ring-type gusset and brake disc are primary Casting and forming avoids generating buckling deformation because of casting geometric dimension asymmetry so that shrinking percentage is obviously uniform when casting is cooling; (2) the machining allowance top of the rubbing surface of the brake disc is designed to the conical surface by plane, increases the resistance of casting deformation, make to cast Part keeps stabilized contraction;(3) by the machining removal cyclic annular gusset after being cooled and shaped, by the rubbing surface of the brake disc Plane is processed on machining allowance top, does not have any influence to casting structure shape, need to only increase a small amount of add in process Between working hour, product dynamic balancing detection percent of pass is greatly improved.
