| Objective The metal extrusion shaper machine jointly developed by Keda Industrial Co. Ltd of Guangdong and Nanchang University has now entered the industrial thermal test phase after assembly and no-load operation. Methods To settle the problem in die adjusting of the lock die in the metal cavity extrusion shaper machine, a lock die adjusting device of two-plate machine type was designed. Results Through constantly improving the lock die adjusting program, the metal cavity extrusion shaper machine successfully achieved lock die adjustment at working temperature, which guarantees the mold in the close nut holds closely the pull rod during the dynamic equilibrium process changing from room temperature to working temperature. Conclusion Throughout the process, automatic height adjustment, lock mode, operating mode, and other actions were successfully achieved between the die adjusting and locking unit, positioner, pull rod and the close nut device close nut device, validating the feasibility of the metal extrusion machine, and creating conditions for the next step of automated production test. |
