Abstract
In a die-casting machine with toggle-joint or without toggle-joint, a threaded section or a shaped section of horizontal columns is made by first carrying out turning and then rolling.
Claims14
A method for manufacturing a horizontal column of a die-casting machine with toggle-joint from a semi-finished cylinder, wherein said horizontal column comprises at least one threaded section comprising a thread for connection to a fixed surface of the die-casting machine, the method comprising carrying out, on the semi-finished cylinder, a turning resulting in a creation of a preliminary profile of at least one portion of the thread, and then carrying out, on the preliminary profile, a rolling to obtain a final profile of said at least one portion of the thread, wherein the turning results in the creation of the preliminary profile having a stock with respect to the final profile, at least at grooves of the thread, wherein the stock has a thickness ranging between 0.5 and 4 millimeters, to obtain a work hardening of material.
A method for manufacturing a horizontal column of a die-casting machine without toggle-joint from a semi-finished cylinder, wherein said horizontal column comprises at least one shaped section for engagement with locking jaws of the die-casting machine, the shaped section being provided with a plurality of raised circumferential ribs, spaced longitudinally, so as to form respective circumferential grooves, the method comprising carrying out, on the semi-finished cylinder, a turning resulting in a creation of a preliminary profile of at least one portion of the shaped section, and then carrying out, on the preliminary profile, a rolling to obtain a final profile of said at least one portion of the shaped section, wherein the turning results in the creation of the preliminary profile having a stock with respect to the final profile, at least at the circumferential grooves, wherein the stock has a thickness ranging between 0.5 and 4 millimeters.
