The precision preformer is composed of a ram extruder and a rubber blank cutter attached to the ram head. It is also equipped with hydraulic, vacuum, heating, pneumatic and electrical system. While in operation, the first step is to open the ram head and add the preheated prehensile rubber material into the machine from anterior part of the barrel. After that, the ram head is to be closed to adjust the extruding and cutting speed (volume control chart is provided with the machine). Eventually, after vacuumization and cutting, the rubber blank with precise weight will then be obtained.
1. Extruding device: It is composed of hydraulic cylinder, batching barrel and ram head.
2. Hydraulic device: This device is selected with high-pressure gear pump and YUKEN flow valve imported from Japan. Hydraulic oil in hydraulic cylinder is controlled by the flow valve and the pressure difference prior to and after throttling is controlled at a constant value so as to ensure the precise weight of the rubber blank extruded. This device is equipped with cooling system driven by 2 sets of hydraulic axletrees which can make reasonabl |
