Description
Technical field
The present invention relates to a kind of high polymer vacuum sheeting equipments, in certain temperature and the vacuum environment of certain pressure, system
Standby certain thickness high polymer laminated structure.
Background technology
High polymer piece is mainly used for the scientific research of biology, material and chemical laboratory, and high polymer vacuum preforming device is
Prepare the necessaries of this piece.
Existing vacuum sheeting equipment, height about 2m, volume about 3m3, occupied space is big.Existing equipment is using simply
Hydraulic pressure is as power source, because without servo mechanisms such as cooperation oil motors, so the degree of automation is low, control accuracy is not high.Simultaneously
Because sealing technique is poor oil leakage, environment easy to pollute easily occur for the design of this oil piping system.Existing equipment in pressure measurement link,
Pressure gauge is installed in lower hydraulic part, measures pressure and is given birth to by simple conversion by the measurement pressure for then passing through hydraulic oil
At, therefore in the pressure transfer process of bolster, the power of loss can not count, so cause the pressure of final measurement with
There are deviations for the true pressure for acting on sample.Because equipment application pressure is larger, and sample area is smaller, according to formula P=F/
S, F deviation are larger, and S is smaller, therefore deviation pressure will produce larger impact to the pressure being ultimately applied on sample, so as to cause
Final display pressure is inaccurate.Simultaneously in packing stage, because of pressure of the setting non-practical function of pressurize pressure on sample, so
The entire pressure maintaining period is caused to be distorted, this phenomena impair experimental precision.
Existing equipment is in the cooling link of heating, and the big structure design of cavity causes heating and cooling rate is low, to
Cause experiment link cannot effective regulated variable, experiment can not reach set temperature in time.During the work time due to equipment
Need vacuum environment, it is therefore desirable to sealing element be installed to form closed containing cavity.The highest of sealing element is heat-resisting currently on the market
Temperature is 200 DEG C, and cavity heating part temperature is generally greater than 220 DEG C, so needing to design cooling structure in equipment to close
Sealing is cooled down.For existing equipment in seal component architecture design, sealing element Cooling Design is unreasonable, leads to sealing element
Ambient temperature cannot be reduced effectively, be easy to cause sealing element（O circles etc.）Heat fatigue is damaged, to cause sealing element loss tight
Weight replaces frequent, maintenance cost height.Because heat radiation is to device measuring sensor（Non-thermal galvanic couple）It is affected, part steel construction
Easy to produce heat fatigue in the high temperature environment for a long time, so as to cause mechanical properties decrease, therefore, it is necessary in equipment design every
Heat structure prevents the transmission of heat with orientation.Since existing equipment volume is big, heating component is more, and invalid heat radiation is big, and equipment

Therefore, as a complete unit, existing equipment occupied space is big, and control accuracy is low, and core parameter measures not accurate, easy consumption
Part consumption is big, and maintenance cost is high.
Solve the problems, such as that previous such equipment exists, it is necessary to be improved to current used equipment, after improvement
Equipment should be with the following functions：First, meeting outside basic function needed for scientific research, the volume of equipment should be reduced as possible, carried
Space-efficient, the consistent image bulky, manufacture is coarse of the equipment that gets rid of stress.Second, since equipment does not need complexity
Multichannel power, therefore dynamic structure should be simplified as possible, dynamical system is made to reach feature succinct, easy-to-use, stable, with high accuracy.
Third, the measurement in core data and control section, should make every effort to that data are accurate, feedback is rapid, and sensor and display system should be able to
Effective statistical data provides guarantee to be analyzed for later data, dynamical system should with control system close fit, according to finger
Enable adjustment in time.Specifically, force snesor should be able to accurate feedback product surface pressure, dynamical system should be able to according to setting press
Strong and current pressure adjusts, and closed loop should be formed between sensor and dynamical system.4th, heating and cooling system should more sections
That learns is distributed in around product, should be able to make timely adjustment according to demand for control, reach high efficiency, high-precision feature.The
Five, in the Position Design of sealing element, hyperthermia radiation should be avoided as possible, and the cooling structure of sealing element is designed, should be selected
The suitable type of cooling and cooling duct, make cooling high-efficiency, reduce the loss of sealing element, extend sealing element service life.
6th, in the material selection of thermal insulation board, thermal coefficient is reduced as possible while ensureing heat-barrier material use environment, make every effort to every
It is hot efficient.
