Description
Technical field
The present invention relates to a kind of sand removal method, the sand removal field of especially a kind of resin sand.
Background technique
Sand casting is with short production cycle, and product cost is low, and product batch, size are unrestricted, is always Foundry Production
In basic technology.With the development of technology, sand casting also has with core sand material and constantly improves.Self-hardening resin sand can
At normal temperature by the effect of catalyst, voluntarily hardened forming, since its intensity is high, moulding is convenient, and type core dimensional accuracy is high,
It is widely used in castings production at present.Digitlization molding sand processing technology in containerless casting production is also mainly needle at present
Resin sand is processed.With greenization, the development of digitlization casting, the application of self-hardening resin sand will be more and more extensive.
Self-hardening resin sand is compared with clay sand, and intensity is high, and deformability is poor, and after molten metal solidification, sand core is by casting packet
It wraps up in, intensity and hardness further increase, therefore during casting post-processes sand removal, common percussion, vibrating method are often very
Hardly possible destroys sand core, and it is difficult to clear up.It often requires to use the strong jarring casting of pneumatic tool or destruction cleaning is carried out to sand core,
Cleaning process wastes many times and manpower, production flow speed are slow；And since the tools such as pneumatic shovel are in damage type core Shi Zaocheng
Sand grains and dust splash, while jarring casting, with a large amount of noises, dust pollution and the noise for also resulting in workshop are dirty
Dye, affects the environment and operator's health of casting finishing plant.
With the development of foundiy industry, it has been inexorable trend, casting post-processing that casting industry, which makes the transition to greenization, automation,
Process needs convenient, free of contamination sand removal method.
Summary of the invention
For the asking greatly of resin sand mud core sand removal difficulty, dust pollution and noise pollution in existing casting last handling process
Topic, the present invention is based on rotary-cut smashing principle and bernoulli principles, propose a kind of convenient, green non-pollution novel sand removal side
Method.Specifically: the mechanical rotation tool that will can be driven by electricity is combined with the suction sand system based on bernoulli principle, when use
With high-strength solid bit rotary-cut sand mold, it is loose defeated and dispersed, easy to clean that hard sand mold is made by way of punching, while splashing and being scattered
Sand grains, dust by inhale sand system be drawn to collection sand container in, convenient dustlessization sand removal is achieved the purpose that with this.
A kind of novel sand removal drill, including drill bit, swingle and three cross over pipes；The drill bit connects the rotation
Bar applies rotary-cut power to affiliated drill bit by swingle；The swingle is sleeved on the three cross over pipes dust suction end, the rotation
There are gaps in the three cross over pipes dust suction end for bar, and the broken sand of dust is allowed to pass through；The swingle is connect with power source, is mentioned
For rotary power；The end a in the other both ends of three cross over pipe is inlet end, and the end b is outlet side；Gas is from the inlet end
When high speed flows to the outlet side at the dust suction end of three cross over pipe, since bernoulli principle forms negative pressure, by dust suction end
The broken sand of the dust that drill bit rotary-cut generates sucks and enters outlet side along gas flow direction.
Preferably, the power source includes built-in bearing gear-box and built-in energy converting system, and the built-in energy turns
Mechanical energy can be converted to for electric energy or gas pressure by changing system, drive the built-in bearing gear-box to rotate, the built-in bearing
Gear-box is cooperated by gear is converted into rotary-cut power for power, passes to the drill bit via the swingle, realizes the brill
The rotary-cut drilling operation of head.
Preferably, the outlet side connection collection sand system, the collection sand system are used to collect through gas flowing discharge
Dust and broken sand.
Preferably, the collection sand system includes silt box, and the outlet of silt box is provided with filter screen.
Preferably, compressed air is connected when the inlet end works.
Preferably, the drill bit is made of high tough alloy or diamond.
A kind of novel sand removal method, opens the compressed air, and opens drill power source described in claim 1,
The drill is set to drill sand core, compressed air flowing generates negative pressure, sucking drilling at the tee joint pipe dust suction end
The dust of generation and broken sand, dust and broken sand are drawn in the collection sand system with moving air；
Punched on sand core several, keep sand core loose, it is automatic it is defeated and dispersed fall off, or tap defeated and dispersed after casting fall off.
Preferably, the energy input of the power source can be electric energy or gas pressure energy, can be by being driven by electricity or pressing
The driving of contracting air.
Preferably, the permeability that silt box airtightness and filter screen are first checked before the drill is opened.
Preferably, it before opening the compressed air, needs that collection core sand will be placed on using the molding casting of resin sand core
Plastic cloth or container above；Defeated and dispersed core sand after casting is removed to be scattered on plastic cloth or in collection vessel.
Compared with prior art, the present invention have it is following the utility model has the advantages that
1. the broken sand grains dust to splash is directly absorbed into collection sand device, avoids the splashings disperse such as fine sand dust and exist
In air, so as to avoid the dust pollution during sand removal.
2, sand removal makes hard sand mold loose crushing by rotary-cut drilling, to make it loosely fall off automatically, or slight percussion
Casting shakes off, and no a large amount of mechanical impacts or firmly percussion casting process greatly reduce noise pollution.
3. the dust collecting system of the method is run based on bernoulli principle, can be driven using compressed air, for current
Workshop, use are more convenient.
4. final realization of the invention need only make bit feeding complete rotary-cut drilling motion, and inhale sand system and be passed through
Compressed air is completed to inhale sand (dirt), therefore can be there are many implementation；Such as the present invention can both pass through the convenient sand removal of hand-held
Tool is realized, can also be realized by automation control sand removal equipment, therefore is easy to carry out large-scale popularization for Cultivation pattern.
