Extrusion Asia Edition 2-2021

25 Extrusion Asia Edition 2/2021 ➠ Guill Tool & Engineering www.guill.com n Guill Tool推出了具有MAGS胶空 间 调 节 系 统 的 新 型 500系 列 十 字 头。500系列专为弹性体化合物的流动 特性和独特的加工挑战而设计。Guill推 出的这种新型十字头设计的关键特性之 一是机械辅助胶空间（MAGS）调节系 统。新的胶空间调节方法使操作员可以 使用普通套筒扳手从单点进行轻松调 节。调节胶空间时无需多个螺母和螺 栓，这可以缩短调节时间。核心管上的 视觉指示灯让操作员能够查看胶空间移 动了多远，使调节更加准确且可重复。 Guill推出的新型500系列无需硬件 并采用专利凸轮锁设计，无需浪费时间 拆卸和重新固定紧固件，便于拆卸和重 新组装。只需将凸轮螺母转半圈即可松 开并自动从十字头体部取出导流板，这 进一步节省了时间。此外，导流板上没 有底切，在取出导流板时无需挂起任何 材料，从而可以更快速、更轻松地进行 清洁和转换。 新型500系列还采用了最新的中央 平台同心度调节系统，可显著降低工具 压力，可以在不松动端面螺栓的情况下 更轻松、更精确地进行同心度调节。用 于调节螺栓的易取插件还允许轻松地更 换锁定或损坏的调节螺栓，从而进一步 减少维修费用并减少宕机时间。 这种新型橡胶/硅胶十字头的另一 个创新特点是铸铝液体冷却套管，让用 户可以在发生线路阻塞时切换冷却套 管，与传统集成冷却系统相比，进一步 减少了宕机时间。 出新型500系列橡胶/硅胶挤压十字头 Guill means no time is wasted unbolting and re-securing fasteners for disassembly and re-assembly. Only half of a rotation of the cam nut is required to loosen and automatically extract the deflector from the head body, which is another time saver. Also, with no undercuts on the de- flector, there are no material hang-ups when extracting the deflector, allowing for faster and easier cleaning and changeover. The NEW 500 Series also features the la- test Center-Stage concentricity adjust- ment system that significantly reduces pressure on the tooling, allowing easier and more precise concentricity adjust- ments without loosening the face bolts. Easy-Out inserts for the adjusting bolts also allow simple replacement of locked or damaged adjusting bolts, which fur- ther saves on repair and downtime. Another innovative feature of this new rubber/silicone crosshead is a cast alumi- num liquid-fed cooling sleeve that allows the user to switch out the cooling jacket in the event of a line obstruction, again reducing downtime compared to tradi- tional integrated cooling systems. The NEW 500 Series crosshead with MAGS gum space adjustment is a drop- in replacement on most existing NRM lines, however this crosshead design can also be adapted to fit any extruder de- sign or line layout. The addition of a newly designed flow inlet channel reduces the shear and heat that is generated as the materials are being processed. This leads to lower head pressures allowing the material to move through the head in a much more balanced and even flow. All crossheads supplied by Guill are fur- nished with a tool kit for assembly and disassembly as well as a detailed opera- tor’s instruction manual. The engineering team at Guill will gladly assist users in the implementation and operation of the NEW 500 series crosshead.

The 500 Series is designed specifically for the flow characteristics and unique processing challenges of elastomeric compounds. One of the key features engineered by Guill on this new crosshead design is the mechanically as- sisted gum space (MAGS) adjustment system. This new method of gum space adjustment allows the operator to make an effortless adjustment from a single point using a common socket wrench. No more need to struggle with multiple nuts and bolts in order to adjust gum space, which leads to faster adjustments. The visual indicator on the core tube al- lows the operator to see how far the gum space has been moved, making those adjustments much more accurate and repeatable.
