Description

A kind of large-scale light fixture aluminum alloy die casting shaving die

Technical field

The utility model relates to a kind of shaving die, relates in particular to a kind of shaving die of large-scale light fixture aluminum alloy die casting.

Background technology

For shell or the lid series products that blanking, punching press, stretching form, generally pass through die drawn after, no matter be metal, plastics, or other materials, after the punch forming since the edge out-of-flatness of part often all need the part of clout is cut edge.At present, for the technique of cutting edge, repairing, most of method all is to adopt an internal mold and an external mold by four direction, minute four side cuts, and the problem that this side cut exists is complex procedures, inefficiency, production cost height.

Chinese patent Granted publication number: CN201470757U, Granted publication day: on 05 19th, 2010, a kind of shaving die is disclosed, comprise that upper die and lower die and guide pillar, guide pin bushing form, wherein patrix comprises punch-holder shank, nest plate, fixed head, on unload piece, counterdie comprises lower bolster, lower bolster, locating piece and pressing plate, be respectively equipped with Pneumatic material pressing device and Pneumatic discharge device in this shaving die upper and lower mould, counterdie is installed punch and die simultaneously.The shaving die that this utility model proposes, its complex structure can't make things convenient for, high-quality removal technique clout.

The utility model content

The utility model is in order to overcome the deficiencies in the prior art part, a kind of shaving die of large-scale light fixture aluminum alloy die casting to be provided, and it is simple in structure, can make things convenient for, efficient, high-quality removal technique clout.

To achieve these goals, the utility model is by the following technical solutions:

A kind of shaving die of large-scale light fixture aluminum alloy die casting, comprise upper die and lower die, also comprise unidirectional unsteady prepressing device, described unidirectional unsteady prepressing device comprises prefabricating plate, spring and pre-briquetting, described spring is fixed between pre-briquetting and the patrix, and described pre-briquetting is fixed on the prefabricating plate.The shaving die of a kind of large-scale light fixture aluminum alloy die casting that the utility model proposes,, ingate large for the aluminum alloy die casting projected area is curved surface distribution, the large technique clout characteristic distributions in ingate distributed areas, adopt the side cut mode, formed by upper die and lower die and unidirectional unsteady prepressing device, it is simple in structure, can make things convenient for, efficient, high-quality removal technique clout, when work, unidirectional unsteady prepressing device is along with equipment is descending, behind pre-briquetting contact workpiece, spring is compressed, thereby workpiece is formed precompression.

As preferably, described shaving die, its side cut edge of a knife comprise the edge of a knife and the lower edge of a knife.In this preferred version, the side cut edge of a knife of shaving die adopts the upper edge of a knife and two kinds of edges of a knife of the lower edge of a knife, and its excision technique clout of the side cut edge of a knife of this structure is more efficient.

As preferably, described shaving die also comprises guide pillar guide sleeve device and limited block, and described guide pillar guide sleeve device comprises guide pillars and bushes.In this preferred version, shaving die comprises guide pillars and bushes, and the upper die and lower die of shaving die by the guide pillars and bushes secure bond together.

As preferably, described shaving die also comprises limited block, and described guide pillar guide sleeve device and limited block are respectively 3 groups.In this preferred version, guide pillar guide sleeve device and limited block all adopt 3 groups, and it is simple in structure for the shaving die that consists of like this.

As preferably, the side cut edge of a knife of described shaving die be shaped as the chopping board type cut-off type.In this preferred version, the edge-trimming cutter mouth-shaped of shaving die adopts the chopping board type cut-off type, and it excises the effective of technique clout the side cut edge of a knife of this shape.

Compared with prior art, the utlity model has following beneficial effect: the utility model is simple in structure, can make things convenient for, efficient, high-quality removal technique clout.
