Description
Technical field
The present invention relates to a kind of compressor opening cover dismounting device and method.
Background technology
Compressor is the core component of electric refrigerator and air-conditioner, either it is carried out keeping in repair, remanufactures or to wherein
Copper, ferrum, the material such as aluminum reclaimed, be required for opening its shell.For the maintenance of compressor or remanufacturing, manual
Open shell to be difficult to meet the welding requirements after repairing, therefore a lot of life-span still unclosed malfunctioning compressor are special because lacking out shell
Machine, can only scrap process, cause the serious wasting of resources.
For the recovery of compressor, disassemble inefficiency and dangerous by hand, increasingly expensive working hour expense makes to tear open
Solution profit is very meagre.Statistics show, in the household appliances that 2013 scrap, refrigerator total amount reaches 1278.57 ten thousand, air-conditioning
For 1529.95 ten thousand.Only this year in 2013 scraps the total amount of compressor and just reaches more than 2,800 ten thousand, adds old accumulation not yet
The compressor disassembled needs out the number of compressors of shell very huge it is seen then that household electrical appliances reclaim industry.Household electrical appliances reclaim in industry at present
The recovery of compressor, most enterprises are still disassembled using original craft, and efficiency is very low, destructive disassemble so that compressing
Machine inner components can only carry out raw material recovery it is impossible to being remanufactured and reusing, and causes the serious waste of resource.
As can be seen here, either the manufacturing enterprise of compressor, repairing trades, or compressor disassemble recovery industry, all
Need badly a kind of efficient, intelligentized, automatically open casing equipment, maintenance and the recovery technology water of household appliances can be significantly improved
Flat, it is greatly improved labor productivity again, makes full use of existing resource, promote the sound development of household electric appliances.
The compressor case of electric refrigerator and air-conditioner generally stretched by low carbon steel plate after welding, thickness is in 3~4mm.Wherein
Cooler compressor mostly is cylinder, and compressor for refrigeration shape is more complicated, and cross sectional shape mainly has circle, oval and band
Rectangle of fillet etc..Method for opening shell of the prior art includes both at home and abroad:
1st, cryogenic pulverization: using liquid nitrogen cooling, the technology of cryogenic pulverization, this technology more than abroad when shell opened by the machine of being compressed
Need to be equipped with a set of liquid nitrogen chiller and metal disintegrating apparatus.And relevant device operating cost is high, energy consumption in shattering process
High, noise is big, serious wear, and shell cannot recycle after being broken, and the part meeting within compressor at very low temperature
Damage, can reuse it cannot be guaranteed that.
2nd, plasma arc cutting: though speed is fast during plasma arc cutting, because the shell of compressor is not smooth steel plate,
But revolving body, during plasma arc cutting, it is difficult to ensure that cutting torch keeps constant distance with case surface, if imprudence
Cutting torch is encountered shell, it will burn out the electrode of costliness.In addition, the air-flow in plasma arc cutting process high speed can will melt
The metal slag particle changed blows to the inside of compressor, brings inconvenience to follow-up remanufacturing or reclaim, or even can burn the electricity of inside
Line.
3rd, flame cutting: the advantage of flame cutting is low cost, cutting speed is fast.Shortcoming is the spray due to gas jet
Penetrate so that Mars, bead and scum splashes, easily cause the accident of scalding of burning;It is melt metal to evaporate under high temperature action, condense
Become metal fumes, suck insalubrity after human body;In addition, bad control flame during cutting, molten metal drop can be right
Compressor inner body impacts.
4th, grinding wheel cutting: be that equipment cost is low using the advantage that grinding wheel is cut, cutting efficiency is high;Shortcoming is to make an uproar
Sound is big, and dust is big, and abrasion of grinding wheel is fast, broken, dangerous.Lathe turning: for cylindrical compressor, can be using common
Horizontal lathe is cutting shell.Clamp the shell of compressor after the claw of lathe chuck can be lengthened, be cut with parting-off tool
Cut.The method utilizes universal machine tools, is not required to special equipment, but can only process the compressor of cylinder, for noncircular cross section
Compressor is helpless, and clamping efficiency is low.Spinning cuts: compressor of air conditioner is cut using spinning process, the method efficiency is low, and
The non-circular compressor in section can not be processed.
5th, profile milling: Chinese invention patent cn1927478a provides a kind of casing opening and disassembly device of waste and old compressor,
This equipment uses profile milling method.But compressor case is formed by punching of the steel plate, appearance has a pattern draft, in milling
It is impossible to ensure that profiling pinch roller is in close contact with compressor case in journey, so may result in and during milling, produce vibration, kerf quality
Difference, cutter is fragile.In addition, the shortcoming of this equipment also resides in completely by manual operations, open shell efficiency low.
6th, first survey and cut afterwards: Chinese invention patent cn100558477c proposes a kind of casing opening and disassembly method of compressor, should
The thinking of method is first to measure to cut afterwards.Before opening shell, appear for the first time by the detecting head of linear displacement transducer with elastic pressure against
Shell in compressor;Then rotary compressor, system gets final product the shape of recording compressed machine shell;Finally control compressor according to
The shape of systematic memory rotates a circle with respect to cutter, thus completing out shell task.In the method, the identification of shell shape adopts
Be contact sensor, specifically open shell practice in, three problems can be brought: one is linear displacement transducer and detecting head institute
Take up space big, shell operation is opened in impact;Two are because not being cylinder but the conical surface near some compressor circumferential weld positions, detecting head with
Shell contact is unstable, thus leading to measurement error excessive;Three is first to survey to cut afterwards, and compressor will rotate 540 ° just to start to cut afterwards
Cut, waste a lot of times, efficiency is low.
Content of the invention
The present invention is for avoiding the weak point existing for above-mentioned prior art, providing a kind of achievable intelligence to melt shell
A kind of device for opening cover of air compressor and method for opening shell, with realize variously-shaped compressor intelligent, automatically melt shell it is ensured that it is cut
