2. Equipment structure:

Structure

Vertical side door opening structure, the     control part is located on the right side of the body; The whole   machine   adopts module integrated structure; A total of furnace body   module, control   module, vacuum system module, hydraulic system module,   movement,   assembly,     maintenance     is     very

convenient;

  Furnace Body

The furnace body adopts double-layer     cylinder vertical structure, and the chamber is made of 304 stainless   steel.   And after precision polishing treatment, water is cooled   between the inner   and outer walls to ensure that the temperature of   the furnace wall is lower   than 55℃. The furnace body is provided with   a vacuum air outlet, temperature   measuring hole, electrode hole,   pressure head

sealing seat, etc.;

Furnace door structure

The furnace door adopts double- layer   water-cooled   side opening structure (convenient loading and unloading   abrasives), the   inner and outer walls are made of 304 stainless steel   and have been precision   polished. The water is cooled between the   inner and outer walls, and the furnace door is provided with an observation   window.

Head seal structure

According to customer production process;     The equipment adopts the lower pressure structure, which can   effectively   avoid the vibration of the material when the customer puts   the material in   the process of pressure movement; The indender adopts   the bellows sealing   mechanism, which is more stable and reliable and   easy to maintain and low   cost compared with the skeleton seal and   Wilson seal ring on the market;

Heating and insulation system

Heating system adopts induction heater;     Uniformly distributed induction coil fixing mode; It can ensure the   best   temperature uniformity and uniform heating of the workpiece in   the furnace,   and facilitate the maintenance and replacement of the   heating body. The heat   preservation system adopts carbon felt heat   insulation screen for heat   preservation.

Heating electrode

The design of the water-cooled electrode     not only ensures a good seal and insulation with the furnace body, but   also   has good contact with the connecting line of the power supply,   and is easy to   disassemble. The water cooling device in the electrode   can reduce the   temperature of the conductive joint and prevent the   burning of the vacuum   sealing material, which affects the vacuum   degree in the furnace. The new   electrode structure avoids the   phenomenon of copper pipe corrosion and   welding joint corrosion and   water leakage during long-term use.

 Pressuri zation system

The press is composed of four columns and     upper and lower beams, the pressure cylinder is fixed on the beam, the     furnace body is supported on the furnace frame, and is fixed with the   lower   beam, the beam is strictly machined to ensure the pressure    accuracy of the upper and lower pressure   head. The pressure system is   composed of hydraulic station, pressure   cylinder, pressure sensor,   pressure displacement sensor, etc., and is   controlled by the solenoid   valve through the control system; The instrument   can automatically   adjust the pressure through the proportional relief valve,   so as to   achieve pressure regulation and pressure preservation.

 Vacuum system

In order to reduce the area of the     equipment and the weight of the switchboard and the convenience of     maintenance, under the condition of ensuring the same performance, the vacuum     system is now using a molecular pump, bipolar rotary vane vacuum pump,   high   vacuum baffle valve, vacuum gauge, vacuum pressure valve, vacuum   pipe, etc.,   and has a

charging interface. In order to reduce     the vibration of the furnace body, the connection   between the   vacuum pipe and the pump is made of metal bellows, and the vacuum     measurement is measured by the   resistance vacuum gauge.

Reasonable design of vacuum unit can make     the vacuum degree of the equipment up to 5X10-3pa; The vacuum system   valves   are pneumatic control, all key switch points are written into the   touch   screen, integrated operation; The vacuum unit has an integrated   frame; Ensure   that the vacuum system can be fixed     independently;

  Rapid    cooling   system

The equipment is equipped with a rapid   cooling   device, which directly passes inert gas into the heating   furnace to bring out   the heat in the furnace through the heat   insulation screen (because the   furnace body has a sealing device as a   whole, it will not affect the sealing   of the furnace body); The gas is   eliminated through the outlet interface of   the water cooling device;   To ensure the service life of its solenoid valve, and operation safety;

  Water    cooling   system

Water cooling system consists of inlet     water pipe, return water pipe, valve, line, etc. Through the pipeline   supply   vacuum unit, furnace body, heating electrode and so on. The   water cooling   system is connected with the control system, and when   the water is low, the sound and light alarm is automatically carried out, and   the heating power supply function   is automatically cut off to ensure   the safety of the equipment. The backup   water device of the equipment   is prepared by the customer, and the backup water flow rate is ≥ 10m3/h.

 Control system

Temperature control is through the     digital display temperature program controller according to the user-set     process curve, the implementation of automatic control temperature,   and with   PID

self-tuning function, can also be     manually

controlled according to user needs. The     control system adopts IEC standard, selected electrical components and     measuring components, simple and intuitive operation. Including: the   whole   control cabinet 1 set, including: button, indicator light, alarm,   air switch,   contactor, cable bridge and so on. The whole electric   furnace in the working   state, with water pressure under pressure, over   temperature, over current   automatic interlock and alarm, protection   and cutoff the main power supply   function. The alarm state is the   screen display mode.

 Automatic control

The control system is divided into manual     automatic dual mode; According to customer requirements:

All temperature, pressure procedures,     vacuum systems and press systems are integrated in the touch screen;     Customers only need to start with one key, the equipment can run the   vacuum   unit of the equipment and pressure, pressure and other process   actions.

 Temperature monitoring

In order to allow customers to better     observe the temperature of the workpiece in the hot press furnace, the     equipment is designed with infrared thermometer to display the   temperature in   the furnace in real time, so that customers can adjust   the process according to the actual situation;

  Data recording system

According to the customer process, the     touchscreen needs to record the data, and the history record

can be consulted (material recorder     function) :

1: main control temperature PV,SV;

2: vacuum value;

3: press value PV,SV;

4: gas lifting pressure;

The above temperature is required to have     the effect of data report and curve display, which is convenient for   customers to read;

Security protection

Equipment with over temperature, pressure     over pressure, gas path over pressure, break even alarm automatic   power off, over current, leakage protection function, simple operation, safe   and reliable;
