Example six:
referring to fig. 7, the present embodiment adopts a hydraulic edge trimmer according to a third embodiment of the present invention, and the present embodiment is different from the fourth embodiment of the present invention in that: in this embodiment, the feeding step is before the blanking step, the blanking step is after the discharge step, and the discharge step is between the feeding step and the blanking step and between the blanking step and the blanking step. Specifically, the working process of the control method for discharging the rim charge comprises the following steps: the feeding robot 30 performs a feeding process, and then discharges the cut-off rim charge of the previous workpiece out of the rack 10 by using the upper die assembly 21 and the discharging assembly 52 provided on the feeding robot 30 to perform a discharging process, and then performs a cutting process by using the upper die assembly 21, and then performs a discharging process again by using the upper die assembly 21 and the discharging assembly 52 provided on the discharging robot 40 to discharge the cut-off rim charge out of the rack 10, and finally the discharging robot 40 performs a discharging process. Through going up mould subassembly 21 and setting up row material subassembly 52 on material loading robot 30 and carrying out row material process between material loading process and blank process, can discharge the rim charge that last work piece was cuted out frame 10, prevent that the rim charge that last work piece was cuted from falling into the range of work of lower mould subassembly 24, influences mould subassembly 21 and carries out the blank process. By arranging the discharging process between the blanking process and the blanking process through the upper die assembly 21 and the discharging assembly 52 arranged on the blanking robot 40, the cut-off rim charge can be timely discharged out of the frame 10 to prevent the cut-off rim charge from falling into the processing range of the lower die assembly 24, so that the blanking robot 40 cannot perform the blanking process and cannot normally process the next workpiece.
The hydraulic cutting machine 100 provided by the invention utilizes the rim charge of the workpiece of the upper die assembly 21 fixedly connected with the first driving assembly 11, the cut rim charge is clamped and embedded in the clamping assembly 22 of the upper die assembly 21, then the rim charge clamped and embedded in the clamping assembly 22 is discharged out of the clamping assembly 22 by the upper die assembly 21, and the rim charge discharged by the clamping assembly 22 is discharged out of the machine frame through the discharging assembly 52 by utilizing the dead weight of the rim charge falling to the discharging assembly 52, so that the problem that the next workpiece cannot be normally processed due to the fact that the rim charge discharged by the clamping assembly 22 falls in the processing range of the lower die assembly 24 is avoided.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
