The invention discloses a barrel-shaped part progressive die which comprises an upper template and a lower template, wherein a cavity blanking die, a strip cutting die and a forming die are arranged between the upper and lower templates in sequence; the strip cutting die comprises a cutting die upper backing plate, a cutting die upper male die, a cutting die female die and a cutting die lower discharging plate; the cutting die upper backing plate is arranged at the bottom of the upper template; the cutting die upper male die is arranged at the bottom of the cutting die upper backing plate; the cutting die female die is matched with the cutting die upper male die; the cutting die lower discharging plate is arranged on the cutting die female die; a return spring is arranged between the bottom of the cutting die lower discharging plate and the lower template. According to the barrel-shaped part progressive die, the process members are cut apart after the shape punching is finished to form independent process members, force relation is not caused among the process members of each process and the horizontal consistency of the strips in the stretching process and the correctness of the process steps are ensured.
Description
Technical field
The present invention relates to a kind of progressive die, particularly relating to a kind of progressive die for processing barrel-shaped part.
Background technology
The barrel-shaped progressive die refers to forcing press in a punching stroke, adopt banded punching press raw material, a secondary mould completes with several different station the cold stamping punch die of Multi-step forming stretching process simultaneously, the every punching stretch of mould completes once, material strip fixed-distance moving once, extremely completes to barrel-shaped product.
At present, for common barrel-shaped part, in the design process of the progressive die, because drawing process is all Simulation Based On Multi-step, for the ease of ensureing the level of material, usual employing upwards stretches, and in the process upwards stretched, the forming force of process part processing will be provided (spring of patrix) by the stripper of mould.In upwards shaping process, power due to spring is certain, also be limited, process part processing shaping hit state to death before, stripper can not produce and move up, if stripper has moved up, process part processing can not ensure level, thus cause the step square between each process part processing to change, and this will cause location in follow-up die molding process inaccurate, to the size of process part processing, and the forming stability of mould has a huge impact.
Summary of the invention
The object of the present invention is to provide a kind of barrel-shaped part progressive die, it has the advantages that can ensure that billot Horizontal consistency in drawing process is good and save die cost, to solve the problems referred to above that in prior art, the barrel-shaped part progressive die exists.
For reaching this object, the present invention by the following technical solutions:
A kind of barrel-shaped part progressive die, it comprises cope match-plate pattern and lower bolster, wherein, on described, die cavity blanking die is disposed with between lower bolster, billot knife edge die and shaping mould, described billot knife edge die comprises knife edge die upper padding plate, knife edge die upper male mould, knife edge die die, stripper under knife edge die, described knife edge die upper padding plate is arranged at the bottom of described cope match-plate pattern, described knife edge die upper male mould is arranged at the bottom of knife edge die upper padding plate, described knife edge die die coordinates knife edge die upper male mould to arrange, and stripper under described knife edge die die being provided with knife edge die, return spring is provided with between the bottom of stripper and lower bolster under described knife edge die.
Especially, described die cavity blanking die comprises blanking die upper padding plate, blanking die upper mounted plate, blanking die loading and unloading material backboard, blanking die loading and unloading material plate, blanking die counterdie and blanking die lower bolster, described blanking die upper padding plate is arranged at the bottom of cope match-plate pattern, described blanking die upper mounted plate is arranged at the bottom of described blanking die upper padding plate, described blanking die upper mounted plate is provided with blanking die loading and unloading material backboard, described blanking die loading and unloading material backboard is provided with blanking die loading and unloading material plate, described blanking die lower bolster is arranged on described lower bolster, described blanking die counterdie is arranged on described blanking die lower bolster.
Especially, described shaping mould comprises shaping mould upper padding plate, shaping mould upper mounted plate, forming blocks on shaping mould, shaping mould lower bolster, shaping mould bottom plate, stripper and shaping mould compacted under block under shaping mould, described shaping mould upper padding plate is arranged at the bottom of cope match-plate pattern, described shaping mould upper mounted plate is arranged at the bottom of described shaping mould upper padding plate, on described shaping mould, forming blocks is arranged in described shaping mould upper mounted plate, described shaping mould lower bolster is arranged on lower bolster, described shaping mould bottom plate is arranged on described shaping mould lower bolster, under described shaping mould, stripper is arranged on shaping mould bottom plate, described shaping mould compacted under block is arranged in described shaping mould bottom plate.
Beneficial effect of the present invention is, compared with prior art the described barrel-shaped part progressive die is at the first half of mould, after the profile stamping-out of process part processing completes, process part processing is cut, form independent each process part processing, so just in the forming process of mould, between the process part processing of each operation, can not produce the relation of power, just ensure that the accuracy of billot Horizontal consistency and operation step square in drawing process.And in shaping process, the shaping of process part processing does not need the forming force providing process part processing with nitrogen cylinder yet, but is provided by punch press, so proposes less requirement to the tonnage of punch press yet, save die cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the barrel-shaped part progressive die that the specific embodiment of the invention 1 provides.
Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Refer to shown in Fig. 1, Fig. 1 is the structural representation of the barrel-shaped part progressive die that the specific embodiment of the invention 1 provides.
In the present embodiment, a kind of barrel-shaped part progressive die comprises cope match-plate pattern 1 and lower bolster 2, die cavity blanking die is disposed with between described cope match-plate pattern 1 and lower bolster 2, billot knife edge die and shaping mould, described die cavity blanking die comprises blanking die upper padding plate 3, blanking die upper mounted plate 4, blanking die loading and unloading material backboard 5, blanking die loading and unloading material plate 6, blanking die counterdie 7 and blanking die lower bolster 8, described blanking die upper padding plate 3 is arranged at the bottom of cope match-plate pattern 1, described blanking die upper mounted plate 4 is arranged at the bottom of described blanking die upper padding plate 3, described blanking die upper mounted plate 4 is provided with blanking die loading and unloading material backboard 5, described blanking die loading and unloading material backboard 5 is provided with blanking die loading and unloading material plate 6, described blanking die lower bolster 8 is arranged on described lower bolster 2, described blanking die counterdie 7 is arranged on described blanking die lower bolster 8.
