Preferably: and positioning bolt holes are symmetrically formed in the front and back of the middle of the fixed workpiece, and the positioning bolt holes are used for fixing the hydraulic base for the fixed workpiece, so that stamping is facilitated.
Preferably: the diameter of the slot hole at the upper end of the binding slot hole is larger than that of the slot hole at the lower end, so that the punching needle is convenient to hold.
Preferably: and fixing bolt holes are formed in the bottoms of the tightening grooves close to four corners.
Preferably: bolt holes are formed in the positions, close to the four corners, of the pressing plate, and correspond to the fixing bolt holes, so that the bolts can be conveniently fixed for the pressing plate and the fixing bolt holes.
The utility model has the technical effects and advantages that:
1. When the punching device is used, the punching needle is placed in the tightening slot hole, and the diameter of the slot hole at the upper end of the tightening slot hole is larger than that of the slot hole at the lower end of the tightening slot hole, so that the punching needle is hung on a fixed workpiece, and the pressing piece is fixed through the bolt, so that the corresponding punching stability is improved, and the practical capability is improved.
2. When the utility model is used, a fixed workpiece descends on the slide bar through the movable hole, and after the workpiece to be punched is punched, the workpiece to be punched contacts with the base, and the upper end of the punching needle is back-pressed to the pressure-avoiding cushion plate, so that the pressure-avoiding cushion plate is retracted to reduce impact, and the pressure-avoiding effect is realized.
