Description
Technical field
The utility model relates to a kind of progressive die.
Background technology
Original progressive die is generally the less aperture in aperture in the hole of blank upper punch; while carrying out aperture moulding; its corresponding punch is elongate rod; strength and stiffness are poor, and in the time of stamping-out, punch is easy to produce flexural deformation and fractures, when being rushed material when thicker; punch more easily ruptures; to often shut down replacing punch, reduce operating efficiency, increase die cost.
Utility model content
Technical problem to be solved in the utility model be to provide one have simple in structure, the progressive die of the advantage of low cost of manufacture.
For solving the problems of the technologies described above, the utility model provides a kind of progressive die, comprise nitrogen spring, upper bolster, convex module, die piece, die shoe, spring, retainer piece, material strip, stripper bolt, it is characterized in that: on described nitrogen spring, be connected with upper bolster, described upper bolster lower end is connected with convex module, described convex module lower end is connected with die shoe, on described die shoe, be connected with spring, described spring upper end is connected with retainer piece, described die piece upper end is provided with material strip, and described nitrogen spring left end is provided with stripper bolt.
Further, described upper bolster and die shoe be arranged in parallel.
Further, described convex module has two.
Compared with prior art, the beneficial effects of the utility model are:
The utlity model has simple in structure, the advantage of low cost of manufacture.
