Place.
4. structure is reliable：
Since the lower die of the utility model is equipped with the bar hole of serial different pore size.Therefore, the blanking of the utility model
Side block device also corresponds to and is equipped with longitudinally adjust slot along longitudinal direction on side shield pedestal, and the bottom of side shield is made to be connected by fastener
On the longitudinally adjust slot, pass through the longitudinally adjust slot, the different location of adjustable side baffle, so as to make side shield adapt to resistance
Keep off the blanking of different specification size bar.
5. punching precision is high：
Since the utility model is also also equipped with bar length adjustment device on lower die connecting seat, the bar length adjustment
Device includes fixed length baffle, and fixed length baffle is equipped with bar location hole corresponding with lower die series bar hole；The fixed length baffle
Mounted on the other end opposite with lower die, lower die connecting seat is equipped with lateral adjustments slot, fixed length gear in the position of corresponding fixed length baffle
Plate is connected to by fastener II on the lateral adjustments slot.When work, bar passes through the bar hole of lower die, end to be located at fixed length gear
In the bar location hole of plate, when punch is punched bar, due to the supporting role of fixed length baffle, punch can be made precisely to determine required
Bar length dimension.Further, since fixed length baffle can also horizontally slip along lateral adjustments slot, to can also adjust bar
It is punched length.
6. reducing the design evaluation work of mold early period, reduce the modification of mold
