The utility model discloses a split type extrusion shaft. The split type extrusion shaft comprises a split type upper end, an extrusion shaft body and a connecting bolt, the top end face of the split upper end is provided with a positioning hole, and the bottom end face is provided with a first step structure. A second step structure is arranged at the top of the extrusion shaft body, and a threaded hole is formed in the end face of the second step structure; connecting bolts penetrate through the positioning holes to be connected to the threaded holes, and the upper ends of the split bodies and the extrusion shaft body are connected into a whole. According to the extrusion shaft, the problem that the extrusion pad on the existing extrusion shaft is inaccurate in positioning is solved, the extrusion shaft can be smoothly mounted and dismounted, the total height of the extrusion shaft can be recovered, and complete punching and shearing are realized. 本实用新型公开了一种分体式挤压轴，包括：分体上端、挤压轴本体和连接螺栓；分体上端的顶部端面设置有定位孔，底部端面设置有第
