1. Main Purpose: ��Owing to the development of modern industry, especially on the development of railway, underground and city track vehicles, the requirement on the large thin-walled hollow aluminum alloy has been thereby more higher. Since the end of last century, countries all over the world have developed our new large-scale extrusion machine. However, in the current time, China's large-scale extrusion products mainly used in the production of large-scale special alloy steel products, such as vehicles competition. This is because the quality of such aluminum alloy will be directly related to the intensity and auto assembly quality .Aluminum quality is mainly manifested in two aspects: First, the strength index of materials as well as position tolerances. The matrix strength depends on the quenching method. In general, large profile can meet the strength indicators after water quenching. According to the reflection from Changchun Car Plant, currently, the twisting, curving and arching of such proximate matter is generally too large, and greatly affect the vehicle assembly accuracy. In other words, it is essential to equip with a high standard of roller-correction machines, to raise the profile Yield. �� Taicang Huayu Machinery Co., Ltd is professional plant in producing extruder rear equipment. The company has initially developed the roller machine matching with large extrusion machine. <table cellspacing="0" cellpadding="5" width="580" border="0"> <tbody> <tr> <td valign="top" width="246"> (2) Application scope: Material, aluminum and aluminum alloy tensile strength materials : Maximum Rm�� 350N/mm2 Width: 100��750mm High: 100��300mm Thickness 2��20mm (3) Main technical parameters of Equipment Structure: Dragon door, roll Maximum width 750 mm Plastic roller: 8 (Number) Adjustment means of Plastic roll: manual operation Horizontal: Hydraulic motors Plastic roller diameter: 200mm Plastic shaft diameter: 110mm Driving roller diameter: 400-600mm Adjustment precision: ��0.1mm Plastic speed: 3-15m/min </td> <td width="314"> </td></tr></tbody></table>
