摘要： The double tapered die mount defines a channel to support the die shoulder. No contact occurs between the die and die housing. The die shoulder is machined to be in generally congruent relationship with the channel shape of the die mount of the invention. In the prior art, the die shoulder is perpendicular to both the inner radial surface and the outer radial surface of the die mount. In the preferred embodiment, the die shoulder is tapered from the inner radial surface toward the die edge to define an inner die taper. The die shoulder also tapers from the outer radial surface to the die edge to define an outer die taper. The side walls of the channel defined by the die mount of the invention taper inwardly to be congruent with tapered surfaces of the die shoulder. The inner channel wall, i.e., the channel wall closer to the axis of rotation of the die, contacts the inner die taper. The outer channel wall, i.e., the channel wall farther from the axis of rotation of the die, contacts the outer die taper. The inner channel wall and the outer channel wall taper toward each other in the direction toward the base of the channel. The edge of the die shoulder does not contact the bottom of the die mount channel, and therefore, a gap exists between the bottom of the die mount channel and the die edge. Both radial forces and torque forces resulting from operation of the pelletizer are taken up by the mated tapered surfaces.
摘要翻译：双锥形模具安装件限定了一个支撑模具肩部的通道。模具和模具外壳之间不会发生接触。将模肩加工成与本发明的模具座的通道形状大致一致的关系。在现有技术中，模具肩部垂直于模具安装座的内径向表面和外径向表面。在优选实施例中，模肩从内径向表面朝向冲模边缘逐渐变细以限定内模锥度。模肩也从外径向表面到模具边缘逐渐变细，以限定外模锥度。由本发明的模具座限定的通道的侧壁向内逐渐变细以与模肩的锥形表面一致。内通道壁，即靠近模具旋转轴线的通道壁接触内模锥形。外通道壁，即距离模具旋转轴线更远的通道壁接触外模锥形。内通道壁和外通道壁朝向通道底部的方向朝向彼此逐渐变细。模肩的边缘不接触模具安装通道的底部，因此，在模具安装通道的底部和模具边缘之间存在间隙。由造粒机的操作引起的径向力和扭矩力均由配合的锥形表面吸收。

摘要： The single tapered die mount employs a radially inner surface at an angle to the axis of rotation of the die mount, die and die holder. The radially inner surface of the die mount acts on an annular shoulder of the die to support and position the die in the die holder. The die mount of the invention is located between the radially outer surface of the die and the extended lip of the die housing. In the preferred embodiment of the invention, the radially inner surface of the die mount in contact with the radially outer surface of the die shoulder has an angle of a modified Morse taper. The radially outer surface of the die shoulder is machined to a matching angle.

摘要： The present invention employs a main shaft cantilevered from a frame. A die holder is disposed around the outside of the shaft, and in the preferred embodiment rotates by the use of adjustable tapered roller bearings around the shaft. Fixed to the die holder is a die, and the die and die holder define a pelletizing chamber. The shaft supports a roller frame with a plurality of rollers within the pelletizing chamber. The resulting construction is a pelletizer shaft support structure that uses only a single set of bearings. In the preferred embodiment, the main shaft is comprised of an inner shaft and an outer shaft. The inner shaft is located coaxially within the outer shaft and supported within the outer shaft by static bushings. The roller frame and rollers are mounted to the inner shaft. The inner shaft and the outer shaft are both fixed to the frame structure. The outer shaft is fixed in a permanent manner while the inner shaft is fixed to the frame by use of a shear pin to allow rotation under emergency circumstances. During operation of the mill, should binding of the roller mechanism in relation to the die result in undue torque being placed upon the inner shaft, the shear pin will shear and allow the inner shaft and the outer shaft to rotate relative to each other to protect the mechanism from further damage.
摘要翻译：本发明采用从框架悬臂的主轴。模具保持器围绕轴的外侧设置，并且在优选实施例中通过使用围绕轴的可调节的圆锥滚子轴承来旋转。固定在模具座上的是模具，模具和模具座定义了造粒室。轴支撑在造粒室内具有多个辊的辊框架。所产生的结构是仅使用单组轴承的造粒机轴支撑结构。在优选实施例中，主轴由内轴和外轴构成。内轴同轴位于外轴内，并通过静态衬套支撑在外轴内。滚子框架和滚子安装在内轴上。内轴和外轴均固定在框架结构上。外轴以永久的方式固定，而内轴通过剪切销固定在框架上，以便在紧急情况下旋转。在轧机操作期间，如果轧辊机构相对于模具的结合导致内轴上施加不适当的扭矩，则剪切销将剪切并允许内轴和外轴相对于彼此旋转以保护机制进一步损坏。
