русский1. Holder unit
The particularly important point of the pressing plate unit is that the pressing surface and the die surface have the correct parallelism and the balance of the buffer pressure is required.
2. Misfeed detection unit
When stamping with continuous dies, the die must be designed with an error detection unit to detect whether the change in feeding pitch exceeds its benchmark and stop the operation of the punching machine. The error detection unit is installed inside the mold. According to the detection method, there are the following two installation forms: (A). The detection pin is installed in the upper mold. When it deviates from the hole of the material strip, it will contact with the material strip detected by contact. (B). The detection pin is installed in the lower mold, and it will be detected when a part of the strip touches the detection pin.
3. Waste cutting unit
During the continuous stamping process, the strip (waste) will leave the mold one after another. There are two ways to deal with it: (A). Coil it with a coiler, (B). Use a mold cutting device to thin it. There are two methods for the latter: (A). Using a special scrap cutting machine (set outside the stamping machine), (B). Installing the cutting unit in the final process of the continuous mold.
4. Height stop block unit
The main function of the height stop block unit is to correctly determine the position of the lower dead point of the upper die. There are two forms of it: (A). It is often contacted during stamping processing; (B). It is only contacted during assembly and stamping processing The way of non-contact. In addition, when the mold is transported and stored, in order to prevent the 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 standard of use can be adjusted by screws.
