    Machine introduction

    1. Molding and cutting system
    Forming and cutting station adopts four-column orientation, five-fulcrum structure, with 15KW servo motor forming and cutting integration, more stable operation, compared with the hydraulic system has more energy-saving characteristics;
    The swing arm shaft is made of high-grade nitriding steel 38CrMoAl, which can obtain high wear resistance after heat treatment and surface salt bath nitriding treatment, and improve the fatigue strength and bending strength. And there are three spiral oil grooves on the swing arm shaft, which further improves the service life of the parts with sufficient oil lubrication;

    3. Heating system
    It is divided into upper furnace (10 zones and 14 rows) and lower furnace (9 zones and 14 rows). The heating tile adopts embedded ceramic far-infrared radiation component, single heating power is 800W, high thermal effect and high safety. The electric furnace is embedded with vacuum insulation cotton, which makes the temperature more concentrated and saves energy.
