Description
Technical field
The utility model relates to a kind of mould, and particularly a kind of off-course brake cylinder body sand mold mould, belongs to Wind turbines field.
Background technology
Along with the allowable exploitations such as oil, natural gas and coal are decayed day by day, its price is constantly soaring promotion also, the climate change that the use of traditional energy brings simultaneously also threatens the survival and development of mankind itself gradually, under the severe environments that the energy and environment perplex, world energy sources to occur to change, namely by the complete energy based on fossil energy was to the conversion of regenerative resource aspect originally, solar energy, wind energy and other renewable sources of energy are as emerged rapidly in large numbersBamboo shoots after a spring rain, flourish.Wind power plant has become equipment manufacturer and has captured new highland, market.Then, because the change of the change of occurring in nature wind speed, wind direction is often changeable, the less change of wind speed all will cause the larger change of wind energy, cause the power output of Wind turbines to be in the state of constantly change thus, therefore in Wind turbines, need capturing wind energy as wide as possible.
In order to farthest capturing wind energy, need to utilize driftage rotary motion to make blade just to wind direction.Several typhoon group of motors off-course brake is housed usually on Wind turbines, and be under Hydraulic Station fluid power orders about during their work, upper and lower braking clamp body clamps brake disc by friction plate simultaneously, and produces the braking moment contrary with the direction of motion on the disc brake rotor.Its mode of operation has two kinds: when engine space and blade need to brake during direction yawing rotation just windward under driftage hydraulic coupling, damping friction effect is folded in the friction plate clamping braking of brake; When engine space and blade are to after direction yawing rotation terminates just windward, several brakes vise brake disc simultaneously under grappling hydraulic coupling, make Wind turbines all the time in maximum general work windward, and are in stable generating state with maximum efficiency.Grappling pressure is normally gone off course several times of pressure.Therefore, off-course brake belongs to wind-powered electricity generation key components and parts, plays an important role to the normal operation of Wind turbines.The power of off-course brake comes from the hydraulic power in off-course brake cylinder body, it is the execution carrying substrate that wind power yawing brake operation state realizes that hydraulic operation vises brake disc, belong to wind-powered electricity generation key components and parts, the normal operation to Wind turbines of its stuctures and properties, inherent quality plays an important role.
Wind-powered electricity generation equipment runs on cold, windy and coastal area usually; China is vast in territory, and north-south climate differs greatly, and for northern area, winter temperature is low, and block cast material must guarantee there is good toughness at low temperatures, requires that ability-40 DEG C and following temperature thereof normally run; For coastal area, require that castings material possesses three anti-measures (Defend salt fog, anti-damp and hot, mould proof) performance characteristics.In addition, Wind turbines is generally arranged on the air port places such as high mountain, wasteland, island, the frequent wind-force effect by irregular, break-in, varying duty and strong gusts of wind are impacted, wind turbine start-stop is frequent, it is large to be hit, wind power equipment running environment is severe, and wind power yawing brake cylinder body needs the characteristic with adverse environment resistant.Run because wind power equipment is erected at eminence, and equipment is not easy to frequent maintenance, the maintenance interval determined during equipment de-sign is generally 20 years, even 30 years.Therefore, to reliability and the durability of the fatigue strength part quality of castings material, very strict requirement is had.
Existing electrification component cylinder body adopts nodular iron casting housing structure, in the foundry goods of prior art, because the wall thickness thickness at oil cylinder periphery differs, at fixed position, the boring of installing hole is carried out at the shaping low back of foundry goods, at the oil cylinder periphery section part that wall thickness is larger, the existing thermal center of remittance abroad in foundry goods cooling procedure, the shrinkage cavity of foundry goods can be caused, casting structure is caused to loosen, there will be through problems such as precision problem or cutter fracture, on the section of fixed part, have than oil cylinder periphery also after thick and large section, same meeting is because of thermal center, form loose structure, carry out in boring procedure at fixed part, same meeting is because casting structure loosens, there will be through problems such as precision problem or cutter fracture.
Fig. 8 is the plan structure schematic diagram of existing structure, Fig. 9 be existing structure look up structural representation.Wherein, multiple installing hole 2 needs to utilize machined to complete, and cylinder cavity 1 also needs to utilize machined to carry out counterbore processing.
In existing casting structure, there is following problem:
(1) although low-temperature impact-resistant performance and decay resistance improve and meet instructions for use, also give people durable sensation, foundry goods is heavy, belongs to typical " stupid large thick " product, can not Appropriate application metal material;
(2) owing to not making optimal design, cylinder block casting has thick and large section, cast can form thermal center, casting causes thick middle heart place easily to produce shrinkage porosity defect of contraction cavity, and interior tissue is loosened, easily drill bit sideslip or Cutting Tool Damage phenomenon occur in process, due to cast-internal short texture, also easy generation hydraulic oil seepage causes and scraps;
(3) because foundry goods is heavy, do not meet lightweight requirements, increase the overall weight of wind-powered electricity generation equipment, in manufacture process, percent defective is high, product material and production cost high.
How overcoming in prior art the above-mentioned shortcoming forging and pressing in cylinder body and cast blocks and exist, is the problem needing in Wind turbines cylinder body to solve.
Summary of the invention
The machining amount existed for the casting structure used at present is large, working (machining) efficiency is low, easy generation underbead crack problem, tissue looseness in the heavy thick large section of foundry goods is there is in nodular iron casting housing structure, easy generation hydraulic oil seepage and produce the problem such as shrinkage porosity defect of contraction cavity because of thermal center, the utility model provides a kind of off-course brake cylinder body sand mold mould, its objective is the thermal center overcoming and exist in existing structure, improve the compactness of foundry goods, avoid the leakage of hydraulic oil, reduce the machining amount of foundry goods, improve production efficiency and product quality.
