Basic principle: It is a complete set of equipment for hot pressing the material under vacuum (or other atmosphere) conditions, mainly using graphite or metal resistance heating, and pressurized by the press head or lower pressure driven by the cylinder. At high temperature, the mutual bonding of the raw solid particles of the material, the grain growth, the void (porosity) and the grain boundary gradually reduce, through the transmission of the material, the overall volume contraction, the  density  increases,  and  finally  becomes  a  compact polycrystalline sintered body with a certain microscopicstructure, so as to press the material to form.

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;
