Abstract：

By referencing, digesting and absorbing the traditional ingot feeder for extruder, a new type of ingot feeder for horizontal metal extruder was developed, which achieved the translational movement of jaws by a transfer mechanism composed of a four-bar mechanism and two parallel quadrilateral mechanisms and replaced the moving pair of the traditional telescopic ingot feeder by using a rotating pair. Then, the kinematic equation of the transfer mechanism was established by the geometric method, and the functions of displacement, velocity and acceleration for billet ingot were derived. Furthermore, the displacement curve, speed-time function curve and acceleration-time function curve of the billet ingot were simulated. The results show that the monement trajectory of the billet ingot is a quasi linear motion, and the billet ingot has a deceleration function. Compared with the most commonly used translational telescopic ingot feeder, the weight for the new type of ingot feeder is reduced by 30%, the cost is reduced by 40%, the equipment operation is more reliable, and the non-extrusion time is shorter.
