The main function of rubber vulcanizing machine is to provide the pressure and temperature required for vulcanization. The pressure is generated by a hydraulic system through a hydraulic cylinder, and the temperature is provided by a heating medium (usually steam, heat-conducting oil, etc.). Flat belt vulcanizing machine according to the structure of the frame can be divided into 4 post flat belt vulcanizing machine and C-frame belt vulcanizing machine two categories; According to the number of working layers can be divided into single layer and multi-layer: according to the working medium of hydraulic system can be divided into oil pressure and water pressure.
Working principle of plate vulcanizing machine
When the motor is running, the oil self-storage tank filter enters the oil pump and enters the control valve through the oil pump discharge tubing. At this time, if the hand control valve is in the closed position, the oil enters the cylinder through the control valve and tubing, driving the plunger and the lower template platform to rise. As mentioned above, when the pressure reaches the upper limit specified value, the electric contact pressure gauge contact controls to stop the operation of the oil pump motor. One-way valve automatically shut down, keeping the pressure inside the cylinder . Pressure maintenance drops to the required minimum working pressure. Electric contact pressure gauge contact controls oil pump operation. The oil pressure rises again. Until the curing heating time is complete. The motor stops. Open the mold to take the workpiece.
Fix the mold between the upper and lower platforms. Generally use automatic temperature control electric heat pipe heating. The rubber has been heated for a few minutes. That is, vulcanized fixed properties and shapes. Vulcanizing machine has some functions like steaming steamed buns. !
If the manual valve is opened, there is a lifting platform and the plunger weight effect, the oil in the cylinder through the cylinder manual valve and tubing pressure back to the oil storage tank, the lower template hot plate down, the electric contact pressure gauge is controlled on the control valve, and connected with the hydraulic cylinder.
Scope of application of vulcanizing machine:
Vulcanizing machine is suitable for O-ring, mobile phone, computer keyboard, remote control, grinding wheel, children’s wheel and other key products and pressure cooker, rice cooker seal washer, household appliances accessories, food, health, medical equipment accessories. Pacifier, medical supplies, health supplies, handicrafts, toy seals, conductive rubber, auto rubber parts, industrial rubber parts, medical silicone products, sports equipment, all kinds of utensils, multi-layer mold products and other complex silicone and rubber accessories production, processing.
