The computer version of the precision pre-forming machine is mainly composed of a plunger extrusion device and a rubber blank cutting device installed on the head. In addition, it is equipped with a hydraulic system, a vacuum system, a heating system, a pneumatic system and an electrical system. When the precision preformer is working, the head is opened, the preheated and rolled rubber material is loaded from the front of the barrel, the head is closed, the extrusion speed and cutting speed are adjusted, and the required rubber blank weight is set. Closed-circuit feedback, you can get the rubber embryo with accurate weight.


1.Extrusion device: It is composed of barrel, head, hydraulic cylinder, etc.


2. Hydraulic device: high-pressure gear pump is selected, and the flow valve is imported from Japan YUKEN (Yuken) product. The hydraulic oil of the hydraulic cylinder is controlled by the flow valve. The pressure difference before and after throttling is always controlled at a constant value by the pressure difference valve to ensure Accurately control the weight of the extruded rubber blank.


3. Pneumatic device: used to control the movement of the machine head to open and close the cylinder.


4.Vacuum system: Before extruding the rubber material, vacuumize it to remove the air inside the barrel and head and the gas contained in the rubber material, thereby improving the quality of the next-process vulcanized products.


5. Heating system: adopts water circulation heating method, and the temperature is controlled and displayed by a digital thermostat to ensure the constant temperature of the head and barrel.


6. Cutting device: It is composed of a frame, a motor, and a deceleration system. Inverter motor can be selected for stepless speed regulation, and gearbox or four-speed motor can also be selected for variable speed. A transmission device is installed in the lower part of the frame.
