The FE model of the frame of pipe end upsetting machine is built with FE simulation software ABAQUS in the study. With the FE model, the force status of the frame is studied. By which, it is found that stress concentration occurs at the inner corner of the frame and bigger corner radius can improve the stress status; the stress of main cylinder body on the up beam is high because of the action of hydraulic press; the frame is bent outward in the up-down direction and bent inward in the left-right direction when the tube is clamped tightly; the earlier deformation of the frame is improved when the tube is upset, but the torsion deformation is found in the frame; the frame is optimized and the strength and the stiffness of the optimized frame can be satisfied with the requirement of application. The results of the study are very useful to design the frame of the pipe end upsetting machine.
