6. Press plate unit
The particularly important point of the pressure plate unit is that the pressure surface and the die surface have the correct parallelism and the buffer pressure is required to be balanced.
7. Misfeed detection unit
When the continuous die is used for stamping, the die must be designed with a fault detection unit to detect whether the variation of the feeding pitch exceeds its standard and stop the operation of the punch. The error detection unit is installed inside the mold. According to its detection method, there are two installation forms: (
A). The detection pin is installed in the upper mold. When it deviates from the hole of the strip, it will Contact and detect.
(B). The form of the detection pin installed in the lower mold is detected when a part of the strip is in contact with the detection pin.
8. Waste cutting unit
During the continuous stamping process, the strip (scrap) will leave the mold one after another. There are two ways to handle it: (A). Using a coiler to take it up, (B). Using a die cutting device to refine it. There are two methods for the latter:
(A). Use a special scrap cutting machine (installed outside the press machine)
(B). Install the cutting unit in the final process of the continuous mold.
9. Height stop block unit
The main function of the height stop block unit is to correctly determine the position of the bottom dead center of the upper die. There are two forms:
(A). It is also often contacted during stamping processing,
(B). It is contacted only during assembly, and stamping processing. Time-free approach. Also, when the mold is transported and stored, in order to prevent contact between the upper mold and the lower mold, it is better to insert a spacer between the upper mold and the lower mold. When the accuracy requirements are not necessary, the use standard can adopt the screw adjustment type.
