During the extrusion, a mixture is passed through a die which provides a cylindrical shape to the outer peripheral surface of the mixture. A plurality of jaws are disposed downstream of the die for conducting the mixture. Each jaw includes a helical ridge for engaging the outer surface of the extrudate to cause a helical groove to be formed therein which constitutes a chip flute in the tool. During the extrusion, the jaws are moved away from the mixture to terminate formation of the chip groove, whereby a shank portion of the tool is formed.4. 发明授权 Method and apparatus for manufacturing a blank for a rotary cutting tool 有权标题翻译：用于制造用于旋转切割工具的坯料的方法和装置公开(公告)号： US07371344B2 公开(公告)日： 2008-05-13 申请号： US10857499 申请日： 2004-06-01 申请人： Mikael Grönquist, Johnny Bruhn, Mattias Svensson 发明人： Mikael Grönquist, Johnny Bruhn, Mattias Svensson IPC分类号： B22F1/00, B22F3/00, B23B51/00, B21K5/04 CPC分类号： B21C23/147, B22F3/20, B22F5/10, B22F2005/001, B23B51/06, B23B2222/28, B23B2250/12, B23B2251/046, B23P15/32, Y10T407/14, Y10T408/455, Y10T408/9097 摘要： A blank for a rotary tool for chip removing machining, such as a helix drill or an end mill is formed by advancing a mixture of hard metal powder and carrier through an extrusion passage. The mixture is fed past a core having pins secured thereto for forming respective internal holes through the mixture. Then the mixture is advanced through a rotary part that is rotating about a center axis of the extrusion passage, wherein the rotary part and the internal holes become twisted to a predetermined pitch. The mixture is also advanced past a plurality of shaping parts which project transversely into the extrusion passage for shaping exterior chip flutes in the mixture, e.g., by embossing or cutting. The mixture is allowed to harden into a green body, and the green body is then sintered to form a blank. 摘要翻译：通过挤出通道使硬质金属粉末和载体的混合物前进，形成用于切屑去除加工的旋转工具的坯料，例如螺旋钻或立铣刀。将混合物通过具有固定到其上的销的芯，以形成通过混合物的相应内部孔。然后，混合物通过围绕挤压通道的中心轴线旋转的旋转部件前进，其中旋转部分和内部孔变得预定的间距。混合物也通过多个成形部件前进，该成形部件横向突出到挤出通道中，用于在混合物中形成外部切屑槽，例如通过压花或切割。使混合物硬化成生坯，然后将生坯烧结形成坯料。5. 发明申请 Drill having internal chip channel and internal flush channel 失效标题翻译：钻具有内部芯片通道和内部冲洗通道公开(公告)号： US20050047879A1 公开(公告)日： 2005-03-03 申请号： US10841575 申请日： 2004-05-10 申请人： Mattias Svensson, Mikael Gronquist, Johnny Bruhn 发明人： Mattias Svensson, Mikael Gronquist, Johnny Bruhn IPC分类号： B23B51/02, B23B51/04, B23B51/06 CPC分类号： B23B51/0486, B23B51/06, B23B2222/28, B23B2228/10, B23B2270/30, Y10T408/44, Y10T408/455 摘要： A drill for chip removing machining includes a front cutting end, a rear securing portion, and a shank extending therebetween.

The slurry used is based on ethanol-water and contains metal carbide and metallic raw materials as well as stearic acid and a low concentration of polyethylenimine (PEI). The concentration of PEI is 0.01-1 wt % of the raw material weight. This combination results in low-viscous slurries, which require less use of ethanol, energy, manpower, and equipment time in their preparation, handling, and spray drying. The invention also relates to the powder obtained by using the method. 摘要翻译：公开了以经济和环保方式制备，处理和喷雾干燥用于通过粉末注射成型或挤出路线生产碳化钨基硬金属工具或部件的浆料。使用的浆液是以乙醇 - 水为基础，含有金属碳化物和金属原料以及硬脂酸和低聚乙烯亚胺（PEI）。 PEI的浓度为原料重量的0.01-1％（重量）。这种组合导致低粘度浆液，其在制备，处理和喷雾干燥中需要较少使用乙醇，能量，人力和设备时间。本发明还涉及通过使用该方法获得的粉末。PDF内容加载中...$(document).ready(function() {
