Description
Technical field
The present invention relates to the motor manufacturing technology field, be specifically related to a kind of seamless motor housing automation casting technique.
Background technology
Motor refers to realize electric energy conversion or a kind of calutron that transmits according to the law of electromagnetic induction.Its main effect is to produce driving torque, as the power source of electrical equipment or various machineries; Thus, very wide of the range of application of motor; The quantity of annual required manufacturing is also very huge.Motor can produce certain heat in the course of the work, for the radiating efficiency that improves motor to guarantee that motor can operate as normal; Lateral surface as Y series three phase electric machine housing is provided with many heat sink strips; But this housing mainly relies on the mould founding to build molded blank.
The mould that is used for the shape casting mould mainly comprises base plate, drag, cope, interior formation pattern and core rod shaping mould.Because the heat dissipation design of electric machine casing, form pattern in causing behind the molding modeling and be difficult to take out.Have the people to design a kind of assembly formula mould at this problem China, its structure comprise be equivalent to electric machine casing radially line reasonably cut into a plurality of submodules and be used for the reference column of location submodule; This mould is promoted the use of widely in China.Also have the people that mould is designed to bipartial up and down, mould takes out easily after the moulding, but two casees sand butt joints up and down, and the inevitable easy case that occurs rubbing with the hands has seam in the middle of the motor housing of building out, influences outward appearance.Certainly also have the disappearance mould of foreign country's introduction at present in addition, very perfect in theory, owing to change greatly, the early investment cost is excessive in actual the use, is difficult to promote.
Utilize above-mentioned assembly formula Mold Making casting die mainly to may further comprise the steps: 1, submodule to be arranged on the reference column, to make it corresponding with motor target hull shape; 2, said modules is positioned on the base plate, and at a certain amount of black sand of assembly outer side covers; At the sheathed drag in the assembly outside, insert the Hei Shabian compacting backmost, until filling up and tamping then; 3, the drag with parts such as the above-mentioned Hei Sha of being equipped with and interior formation patterns spins upside down, and covers cope then successively and put into to water oral pillar; Sprinkle at last for huskyly the cope inner chamber is filled up and tamping every the pulvis of mould with black; 4, get successively and water oral pillar, black husky cope, reference column is housed and takes off submodule in an orderly manner; 5, can make center die earlier before this, center die is put into forming cavity; 6, black husky cope will be housed again is placed on the drag; 7, take off cope and drag successively.Utilize this assembly formula Mold Making casting die to need will be pieced together by skilled moulder blocks of taking-up of submodule of formula mould, very easily cause down sand during delivery, this mould is to moulder's qualification, and experience requires quite high; This obviously exists the production requirement rising, production cost increases and the low problem of production efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automaticity height, the seamless motor housing automation casting technique of high efficiency.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of seamless motor housing automation casting technique comprises following processing step:
1) sand that shakes
The employing casting die of sand machine after to last consignment of time moulding that shake vibrates, in vibration processes, the shell of moulding separates with the sand mold mould, and shell transports out by output device, the sand mold mould is broken into original sand grains in vibration, sand grains drops on the conveyer from the sand motor spindle outlet of shaking;
2) sand separation
The sand grains that conveyer is separated vibration is transported to and adds in the sand machine, adding the sand machine is sent to sand grains in the sand separation device on demand, in the sand separation device, at first sand grains is cooled off, after cooling is finished sand grains is filtered, by bolter the impurity in the sand grains is separated, qualified finished sand enters sand reservoir box and stores, underproof being transported in the outside gathering-device;
3) batch mixing
On demand the finished sand in the sand reservoir box is sent in the batch mixer, and the additive of moulding needs is joined batch mixer, batch mixer mixes finished sand and additive, and it is stand-by to be prepared into moulding sand;
4) reinforced
The moulding sand that batch mixer prepares is transported to a plurality of automatically add in sand hopper through conveyer with moulding sand by coming out and stores, and by what add the sand hopper correspondence automatically moulding sand amount is on demand joined moulding machine;
5) moulding
Shell model in moulding machine preparation motor housing model and motor is compounded to form casting die with shell model in motor housing model and the motor then;
6) casting
Put into the casting die for preparing on the induction system successively, and be transported to casting system, by casting system casting die is carried out cast molding, casting die after the moulding is transported on the sand machine that shakes by induction system successively and separates, shell body after the separation enters the finished product district, and it is recycling that the sand grains after the separation enters the sand separation device.
The type of cooling in the described sand separation device adopts air cooling way to cool off.
The invention has the beneficial effects as follows: processing step of the present invention is simple, and is one-body molded, simplified operation, can uninterruptedly produce continuously, reduce cost, improve operating efficiency and product quality, and realized the recycling of moulding sand, the motor housing smooth in appearance of preparation does not have the crack.
Description of drawings
Fig. 1 is process chart of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
