The preparation method of a kind of automobile wear-resisting chassis cover plateTechnical field:
The present invention relates to auto parts machinery casting technology field, be specifically related to the preparation method of a kind of automobile wear-resisting chassis cover plate.
Background technology:
Automobile chassis by power train, running gear, steering system and braking system four part form.Chassis effect is supporting, installs automobile engine and each parts, assembly, shaped automotive moulded, and accepts the power of engine, makes automobile produce motion, ensures normally to travel.
And automobile chassis lower end can be provided with cover plate; attractive in appearance on the one hand; being on the one hand to protect chassis, ensureing the generation of the situations such as chassis is not easy to occur to hang up, cracking, and now due to the reason of pavement behavior; the making of many chassis cover plates is with regard to trouble very; due to the particularity of product, the requirement for various aspects such as quality is all higher, and the general equipment produced all costly now; and technique is more complicated all, cost is too high.
Summary of the invention:
Technical problem to be solved by this invention is that overcoming existing technological deficiency provides the preparation method that a kind of method is reasonable, simple to operate, prepare a kind of automobile wear-resisting chassis cover plate easily.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A preparation method for automobile wear-resisting chassis cover plate, is characterized in that: comprise the following steps,
Step one, design shape: design casting pattern and running channel;
Step 2, analogue formation: make shaping by the model paraffin designed, be then placed on ventilation, shady and cool local airing 1-2 days;
Step 3, selection sand: select high temperature resistant sand, in high temperature resistant sand, add polyethylene resin powder, then mix bi-material concussion in earthquake equipment;
Step 4, making cover plate:
The model made places by I, rotational model and be coated on model by quartz sand, makes quartz sand be attached to model surface;
The model made in I is put into running channel by II, makes it shaping pouring into molten iron in running channel;
Step 5, cover plate toast: the cover plate after shaping is put into baking box and toasts, and the temperature of baking is at 422-467 DEG C, and baking 55-71 minute, makes melted paraffin wax become liquid;
Step 6, add inserts: poured out by paraffin, more inwardly add aluminium water, then wait for 12-18 minute shaping, then put into baking box and toast, temperature is 244-262 DEG C, and the time is 37-52 minute;
Step 7, polishing lid surface: the cover plate after baking is put into grinding apparatus, in grinding apparatus, adds the sand chosen in step 3, polished by sand, polishing 20-28 minute;
Step 8, flushing lid surface: the cover plate after polishing is taken out, then uses distilled water flushing lid surface 2-4 minute;
Step 9, meticulous polishing: put into after polishing machine carries out the polishing grinding become more meticulous after the cover plate after flushing is left standstill 1 minute and obtain finished product;
Step 10, inspection product: the cover plate of finished product is tested, qualified packing of product warehouse-in.
Beneficial effect of the present invention is: namely the present invention will wrap up aluminium in iron, and the weight of such product is not very heavy, but hardness height very, very wear-resisting, than simple layer, the quality of the product of single variety is good.The inventive method is reasonable, simple to operate, it is convenient to prepare.
Detailed description of the invention:
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below.
