The invention has two alternatives of manual and automatic, when choosing the automatic work, click the original point and resume the button on the control panel, every apparatus can find the original point position automatically according to the parameter set up, namely every apparatus finds the original point position, at this moment two hands of the workman press a pair of hand operation buttons separately, the apparatus will carry on the automated production according to the parameter input, because two hands operation buttons are in series, need to press two hands operation buttons together left and right, can start the apparatus, avoid the workman to start the potential safety hazard that the button exists while operating the machine, stop the emergence of such accident fundamentally, thus greatly raise the safety coefficient of the machine operation, there are emergency stop buttons on the control panel at the same time, stop immediately in the convenience emergency; when manual operation is selected, the automatic and manual buttons are firstly moved to manual positions, then all the buttons are moved one by one according to production steps, the buttons of the feeder are moved to advancing positions, and the feeder starts to advance. Manual operations are relatively complex and cumbersome and not precise enough to be used in general, but when the invention requires debugging and the use of separate systems, manual operations such as a separate punch press can be selected.
According to the automatic gold bar cutting machine, on the basis of an existing numerical control cutting machine tool, the automatic feeding device and the feeding device are additionally arranged, so that full-automatic cutting is truly realized, after a worker places gold bar blocks into the feeding box, the worker only needs to manually control buttons on a control panel, and a programmable controller can control each module to work so as to perform automatic cutting, so that labor cost is saved, meanwhile, the alignment cutting quality is automatically controlled, the cutting quality is improved while the working efficiency is improved, and the production efficiency of enterprises is greatly improved.
