At first step, the processor before the deformable body contact the end face of cone die cavity regarded as an extrusion process. The minification of core boss's cross-section regarded as compressibility of direct extrusion, which acted as definition factor when construct the Direct Extrusion Model element. Another step, the model element of flat punch extrusion on wedge piece process was constructed when propose the process of deformable body overflow die corner. In this way the spherical end face of blank looked as cone end face one, t he approximate treatment is one of originality innovation in this paper. At last, the two elements have been connected and constructed the model element of cone boss part's deformation in the open die forging.

对于锥形凸台成形的第一个特征时段，即坯料和锥形凸台型腔的端面接触之前的变形过程，本文将凸台的截面缩小率转换成挤压成形的压缩率并以此为界定，建立了不同截面缩小率时的锥形模正挤压的模型单元；对于锥形凸台成形的第二特征时段即锥形模的角部充满过程，在详细考察锥形型腔端面对变形过程影响的基础上，将变形体的球形端面近似成锥面建立了平冲头挤压楔形体的模型单元；最后将前述两种模型单元有机连结，构建了开式模锻中整个锥形凸台成形过程的定量描述。

This invention relates to a method and device for generating cold atomic beam. Said method includes heating hot atom source in vacuum chamber to form atomic saturated vapor pressure atmosphere, cooling hot atom by three-D MOT to below 200uk and trapped to form cold atomic cloud, by the quarter wave plate reflection mirror in MOT the laser radiation pressure being unbalanced to make cold atom emitting along said direction, four tape arranged straight line set with contrary current direction is set in atom beam emission direction, which makes the atom emitted to forward to obtain cold atom beam with low speed, large flux and small transverse speed, laser beam vertical with atom beam set in the direction of cold atom emitting for atom beam state preparation to realize state concordant emitted cold atom beam.

本发明涉及一种冷原子束产生方法和装置，该方法包括在抽真空的真空室内，加热热原子源，在真空室中形成相应的原子饱和蒸汽压气氛；采用三维MOT对热原子进行冷却，冷却到200μk以下，并被捕获形成冷原子云团；通过三维MOT中开小孔的四分之一波片反射镜，而使得在该方向上激光辐射压力不平衡，使冷原子沿此方向出射；在冷原子束出射方向上，还置有载有彼此电流方向相反的四根成锥形排列的直导线，从而原子出射时将在磁场的作用下，不会沿横向膨胀而向前射出；便得到了出射速度低的、通量较大的、横向速度非常小的连续冷原子束；同时在冷原子束的出射方向上，设置有与原子束垂直的激光束，用于原子束的态制备，实现态一致的出射冷原子束。
