This vacuum calibration table barrel is made of stainless steel. It is divided into two sections, with vacuum cooling and spray cooling at the front and rear ends respectively. The stainless steel float water level adjustment has a simple and practical structure. It is used for nozzle materials of ABS engineering plastics. The frame is three-dimensionally adjustable, and the front and rear movement is driven by a cycloidal pinwheel reducer, and the up and down and left and right are adjusted by a screw pair. The barrel body adopts a roller mechanism, which can effectively prevent the barrel body from sagging.
Application:
PVC pipe forming calibration. This machine is used for extrusion molding of PVC pipes. The PVC material formula is quantitatively added to the barrel screw by the feed, and the material is conveyed, compressed, plasticized, and metered by the screw before entering the molding mold. The barrel and screw of this machine are made of 38crmoala, which are forged and tempered; secondary aging treatment and nitriding treatment. What other manufacturers do not have is that the screw frame is rough-processed after quenching and tempering, the material has good hardenability, and the secondary amount is limited, which effectively eliminates stress. At the same time, the processing is excellent, and the screw segment and screw wing phase error is small. The barrel and screw are highly interchangeable. Depending on the material, the screw structure is changing. The distribution box adopts hard-faced gear reducer, which is high in precision and fatigue-resistant. The reducer gear is made of 20crmoala and carburized. The helical gear material of the distribution box is 38crmoala, which is processed by CNC gear hobbing machine and nitrided.
