Description
Technical field:
The present invention relates to casting technology field, specifically is a kind of turning machine that is used for sand on the wax-pattern.
Background technology:
We know that precasting is made metallic article, at first need make the sand mold that inner chamber conforms to metallic article, and then the metallic solution with heating is filled in the sand mold through the sprue gate, treat the metallic solution cooling after, break sand mold into pieces and just obtain required metallic article.Above-mentioned sand mold generally is bonded to by fire resistance very strong quartz sand and processes on the wax-pattern; After the bonding; Put into hot water and melt away wax-pattern and just obtain the sand mold that inner chamber conforms to metallic article, quartz sand is bonded to this procedure that (is commonly called as sand) on the wax-pattern quality of whole sand mold is played key effect, and tradition adopts floating sand machine to accomplish this operation; The wax-pattern that perisporium is stained with the slurry layer is placed on above the sand bucket open top of floating sand machine usually; The high-power high voltage blower fan of sand bucket bottom blows afloat the quartz sand in the sand bucket, and the quartz sand that floats bonds on the slurry layer, and final the completion gone up the sand operation.Use above-mentioned floating sand machine that there are following three weak points usually in sand on the wax-pattern: 1, the air quantity of high-power high voltage blower fan is generally all bigger, and slurry layer sticking on the wax-pattern perisporium is easy to dried up, and causes the quartz sand of suspension to be bonded to equably on the wax-pattern; 2, bigger air quantity can blow afloat the dust in the quartz sand, and the dust that fills the air pollutes the air in the room; 3, the quartzy sand grains that suspends is difficult to enter in the through hole or shrinkage pool that wax-pattern is provided with, and also can't fill up through hole or shrinkage pool fully even get into, and the sand mold percent defective that causes making is higher.
Summary of the invention:
The technical problem that the present invention will solve is, provides a kind of in guaranteeing the room under the situation of air quality, can quartz sand is bonded on the wax-pattern equably and fill up through hole that wax-pattern is provided with or the turning machine of shrinkage pool.
Technical solution of the present invention is; A kind of turning machine with following structure is provided: the rotating shaft that comprises bracing frame, is used for the casing of splendid attire quartz sand and is used for being connected with motor; Bracing frame is connected bottom of shell, and the casing top is provided with discharging opening, and rotating shaft is rotatably connected in the chassis cavity; Rotating shaft circumferentially is evenly equipped with multiple row and throws bowl seat group; Every row are thrown bowl seat group axially all has a plurality of throwing bowl seats along rotating shaft, and adjacent throwing bowl seat quantity of throwing between the bowl seat group differs one and axially be staggered along rotating shaft, and a center line of throwing bowl passes shaft axis and vertical with shaft axis; On the throwing bowl seat throwing bowl that is used to dip and throw away quartz sand is housed, formed angle is 30 °～40 ° between throwing bowl plane of the opening and the throwing bowl seat center line.
Turning machine of the present invention, wherein, angle is 30 ° or 33 ° or 35 ° or 36 ° or 38 ° or 40 °.
Turning machine of the present invention, wherein, angle is 36 °.
After adopting above structure, compared with prior art, turning machine of the present invention has the following advantages:
1, be bonded on the wax-pattern quartz sand different with the air quantity that prior art utilizes high pressure positive blower to produce; Turning machine of the present invention comprises the throwing bowl that is used to dip and throw away quartz sand; Follow rotating shaft when rotating at a high speed throwing bowl, quartz sand will throw away and finally be bonded on the wax-pattern from throw bowl under action of centrifugal force, and this sand mode that goes up can not produce big air quantity; Thereby avoid slurry layer sticking on the wax-pattern perisporium to be done, guaranteed that quartz sand can be bonded on the wax-pattern equably by wind;
2, can not produce big air quantity when the sand on wax-pattern just because of turning machine of the present invention, therefore, the dust in the quartz sand just can not blown afloat, thereby effectively guarantees the air quality in the room;
3, after quartz sand threw away from throw bowl, centrifugal force was bigger, thereby can fill up through hole or shrinkage pool that wax-pattern is provided with, has improved the qualification rate of sand mold.
It is the preferred implementation of turning machine of the present invention that angle is 30 ° or 33 ° or 35 ° or 36 ° or 38 ° or 40 °.
It is the preferred forms of turning machine of the present invention that angle is 36 °.
Description of drawings:
Fig. 1 is the stereochemical structure profile sketch map of turning machine of the present invention;
Fig. 2 analyses and observe the structure for amplifying sketch map along " A-A " among Fig. 1;
Fig. 3 throws the bowl seat to organize the three-dimensional structure for amplifying sketch map when being distributed in the rotating shaft among Fig. 1.
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment turning machine of the present invention is done further explain:
Like Fig. 1, Fig. 2 and shown in Figure 3; In this specific embodiment, the rotating shaft 4 that turning machine of the present invention comprises bracing frame 5, is used for the casing 1 of splendid attire quartz sand and is used for being connected with motor, bracing frame 5 is connected casing 1 bottom; Casing 1 top is provided with discharging opening 6; Rotating shaft 4 is rotatably connected in casing 1 inner chamber through bearing, and rotating shaft 4 circumferentially is evenly equipped with multiple row and throws bowl seat group, and every row are thrown bowl seat group axially all has a plurality of throwing bowl seats 2 along rotating shaft 4; Adjacent throwing bowl seat 2 quantity of throwing between the bowl seat group differ one; Adjacently throw throwing bowl seat 2 between the bowl seat group along axially being staggered of rotating shaft 4, each throw bowl seat 2 all with rotating shaft 4 welding, each throw bowl a center line of 2 all pass rotating shaft 4 axis and with rotating shaft 4 axis normal; On each throwing bowl seat 2 a throwing bowl 3 that is used to dip and throw away quartz sand is housed all, formed angle is 36 ° between throwing bowl 3 plane of the openings and throwing bowl seat 2 center lines.
The operation principle of turning machine of the present invention is: the wax-pattern that perisporium is stained with the slurry layer is placed on discharging opening 6 tops; Rotating shaft 4 is rotation at a high speed under the drive of motor, and throwing bowl 3 is followed rotating shaft 4 and rotated together, and throwing bowl 3 can constantly dip quartz sand from casing 1 bottom and quartz sand is thrown away from discharging opening 6 in rotary course; Quartz sand thrown the bowl 3 throw away after; A part is bonded on the wax-pattern under action of centrifugal force, fills up through hole or shrinkage pool that wax-pattern is provided with, and the quartz sand that another part is not bonded on the wax-pattern can drop on the wax-pattern in the deadweight effect next time; Reach sand does not have the purpose at dead angle comprehensively, and final the completion gone up the sand operation.The charging aperture that above-mentioned discharging opening 6 also can be used as quartz sand uses, and promptly when the quartz sand of casing 1 intracavity bottom uses up, can add quartz sand to casing 1 inner chamber through discharging opening 6.
Above-described embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
