Description

A kind of cutter air-cooled and sediment outflow integral method and device
Technical field
The present invention relates to cutter air-cooled and sediment outflow integral method and device that a kind of casting mould digital control cutting processing former is used, belong to the non-traditional machine tool field of accessories.
Background technology
Casting is to obtain one of main method of engineering goods blank, is the important fundamental technology of mechanical industry.Casting industry is the important foundation industry of the national economic development, is the basis of pillar industries such as automobile, petrochemical industry, iron and steel, electric power, shipbuilding, weaving, equipment manufacturing, is manufacturing important component part.Along with variation, the personalization of product, the demand of single-piece, small lot foundry goods is more and more, especially in the product development development stage, and require with short production cycle, renewal speed is fast.Yet China's single-piece, small lot castings production are still continued to use traditional manufacturing process, not only the manufacturing cycle long, production cost height, and resource consumption is big.In order to address this problem, the digitalization fast manufacturing method of casting mold has been proposed, adopt casting mould digital control cutting processing former directly to process the sand base and obtain casting mold.
But in the casting mold process, the sand that cuts can be taken up by the cutter of high speed rotating, splashes at a high speed; and it is irregular; so not only pollute working environment, and remain in sand grains in the model gap and can increase wearing and tearing, influence the precision of cutter life and machining cutter.In the casting mold process, produced a large amount of antiquated sands, if untimely cleaning, a large amount of antiquated sands just are deposited in the die cavity of processing.Scrap on the sand mold can damage the sand mold surface quality, influences follow-up casting precision, and the sand formation cuttings and the cutter that remain in the model gap produce harmful friction, and the aggravation tool wear reduces cutter life.If therefore untimely cleaning can have a strong impact on crudy and cutter life.When adopting the compressed air sediment outflow, generally adopt the single, double blow-out nozzle cutter periphery that is placed in, but this structure is containing the dead angle aspect the blast chip removal, the part sand formation cuttings can not be blown away timely, thereby quickened the wearing and tearing of cutter, has reduced the service life of cutter.
Summary of the invention
The technical problem to be solved in the present invention, be exactly at the existing in prior technology deficiency, provide a kind of can comprehensive cutter air-cooled and incorporate method of sediment outflow and device, the air-flow that this device can blow out by the gas outlet that is distributed in the cutter periphery comprehensively cools off the scrap that cutter cuts away cutter simultaneously and carries out in time comprehensively cleaning, this device can adjust the size of tolerance by the control strip of changing gas outlet, bottom structure or adjusting depressed structure, and adjustment process is simple, convenient, fast.
Air-cooled and the incorporate method of sediment outflow of a kind of cutter, it comprises following content:
1) compressed air with compressed gas source is transported to the air-cooled and sediment outflow integrated apparatus of cutter by tracheae;
2) the annular uniform gas outlet shunting in the air-cooled and sediment outflow integrated apparatus forms even high velocity air around cutter to compressed air by cutter;
3) antiquated sand that also cutter cut away simultaneously of the heat on the high velocity gas stream cutter cutting zone that blows off;
Gas outlet in the air-cooled and sediment outflow integrated apparatus of cutter can or be changed the bottom end cap of giving vent to anger and control the size of gas outlet by control strip, and process is simple and convenient.
Air-cooled and the sediment outflow integrated apparatus of this cutter comprises middle part retainer ring, upper end capping, bottom give vent to anger end cap, control strip, sealing ring, setscrew nut and manual composition such as post.
The middle part retainer ring is provided with air inlet pipe installing hole and holding screw installing hole, and described air inlet pipe installing hole links to each other with the tracheae of outside, and holding screw installing hole and screw fit are fixed on whole device on the shaft shoulder of electric main shaft location.
End cap and middle part retainer ring are given vent to anger by being threaded in top end cap and bottom, between upper end cover and the middle part retainer ring circular seal ring are housed, and giving vent to anger in the bottom has the quad seal circle between end cap and the middle part retainer ring.
Give vent to anger end cap and control strip of bottom installed with one heart.
Control strip and outlet side cover that to be provided with annular uniform gas outlet and gas outlet shape consistent, the device gas output can change the gas outlet size by the rotation control strip and regulate, give vent to anger gas outlet on end cap and the control strip, bottom can specifically require to be provided with the shape of corresponding quantity and gas outlet according to processing environment, reach optimum cutter cooling and sediment outflow effect.
Utilize the cylinder of middle part retainer ring, upper end capping and the electric main shaft location shaft shoulder to constitute the triangle wedge shape on the hermetically-sealed construction, three part co-extruded sealing rings reach good sealing effectiveness, this is simple in structure, easy for installation, this device is simple on overall structure, easy-to-use, easy to maintenance, and can reach the good effect that cutter is air-cooled and scrap is cleared up.
