Mould fixed plate, the piercing punch are fixed on punch retainer.
Preferably, the driving unit includes the screw rod that driving motor and driving motor drive, and is arranged on the lower inclined wedge
There is the threaded hole with screw rod cooperation.
For the height for reducing inclined wedge, the lower inclined wedge is provided with one group in lower bolster, and adjacent two lower inclined wedges are mutually clamped
Connection, the upper inclined wedge is corresponding to be provided with one group, and inclined wedge is bonded to each other on adjacent two.
It is reliable for the adjacent two inclined wedges cooperation of guarantee, it is provided with engaging groove on the upper surface of the low one end of the lower inclined wedge,
The latch for being provided on the lower end surface of high one end and engaging groove cooperation.
For convenience of discharging, it is provided with pressing plate on the die block, lower stripper is provided on pressing plate, the cavity plate is solid
Spring is provided between fixed board and lower stripper；It is corresponding on the punch retainer to be provided with loading and unloading material plate.
It is discharged in time for convenience of waste material, the lower end of the punching concave die extends on lower bolster, the punching concave die
It is inside provided with material-dropping hole, punching concave die relief hole is correspondingly arranged on the lower inclined wedge and upper inclined wedge, the relief hole is waist type
Hole, the length of waist-shaped hole are adapted with the stroke of lower inclined wedge and upper inclined wedge.
The utility model has the beneficial effects that the utility model adjusts the height of punching concave die by inclined wedge, to make to rush
The height of hole cavity plate is adapted with the height to punching convex closure, guarantee punching when cavity plate will not with wall friction in punching, to make
Cavity plate is not damaged.The inclined wedge can reduce the height of entire inclined wedge, using silk using the structure design of multiple groups head and the tail connection
Bar, which promotes, to be adjusted, and has degree of regulation height, the good advantage of stability.
Below with reference to drawings and examples, the utility model is described in detail.
