Abstract
The invention aims at providing a robot base and frame casting process. Through the method that chilling block chilling and secondary metal-stream inoculation are added to the casting process, a casting is adjusted during casting, and the problems that a robot base and frame hot spot part is prone to the shrinkage porosity and insufficient in air tightness are solved.
Description
Technical field
The present invention relates to robot building field, particularly relate to a kind of casting technique for the manufacture of robot base and robot frame thereof.
Background technology
When making machine people, the base of robot and framework play the effect of academic title robot, and the casting of robot base and framework then needs careful operation.Common casting technique comprises Modeling Material preparation, moulding, coremaking, Metal Melting, pours into a mould and solidify control etc., but very easily produce shrinkage porosite by above-mentioned manufacture technics base out and framework thermal center part, and owing to using the method for casting to cast, the air-tightness of base and framework is not enough.Therefore, robot base and the easy shrinkage porosite of framework thermal center part is solved and the problem of air-tightness deficiency just seems particularly important.
Summary of the invention
The object of this invention is to provide a kind of casting technique for the manufacture of robot base and robot frame thereof, by the method for iron chill shock chilling and secondary current-following inoculation, foundry goods being adjusted when casting, solving robot base and the easy shrinkage porosite of framework thermal center part and the problem of air-tightness deficiency.
The invention provides a kind of robot base and framework casting technique, described casting technique step is as follows:
Step one: use sand as main Modeling Material, produce the mould structure needing casting;
Step 2: use chill to carry out Quench process to the heat energy-saving position of foundry goods;
Step 3: mould inside is cleared up;
Step 4: mould is carried out matched moulds, and the molten iron melted is poured in mould;
Step 5: powder shape inovulant is loaded in a funnel by a certain percentage, during cast, this inovulant is flowed in mold cavity together with molten iron;
Step 6: will the mould insulation cooling of molten iron be poured into;
Step 7: the mould after cooled is opened, and foundry goods is polished;
Step 8: ball blast is carried out to foundry goods, and do process of spraying paint, complete procedure of processing.
Further improvement is: the ratio of the inovulant added in described step 5 is 0.2-0.4% of iron liquid weight.
Further improvement is: the temperature being incubated cooling in described step 6 remains between 30 DEG C ~ 60 DEG C, and cool time is 10h.
Beneficial effect of the present invention: the heat energy-saving position of product, very easily produces shrinkage porosite, with chill to carrying out Quench herein, refinement internal grain, avoids the generation of shrinkage porosite, reaches machine in use bubble-tight requirement; Adopting secondary current-following inoculation technique when pouring into a mould, powder shape inovulant being loaded in a funnel by a certain percentage, during cast, this inovulant is flowed in die cavity together with molten iron, enhance pregnant effect, cast-internal being organized finer and close.
