For auto parts machinery punching production, single-station die lamps structure is single, and production efficiency is low, and baroque mould, station is less, is unfavorable for the punch forming of product.And the progressive die, use forcing press in a punching stroke, use banding punching press raw material, a secondary mould completes the cold stamping punch die of multi-step forming processes with several different stations simultaneously, the every punching press of mould completes once, material strip fixed-distance moving once, until Product processing completes.
Summary of the invention
The technical problem to be solved is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, the automobile rear backrest left plate progressive die easy to process.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that and realizes: this kind of automobile rear backrest left plate progressive die, include and manufacture mould assembly and progressive die lower mould assembly on the progressive die of automobile rear backrest left plate corresponding construction, it is characterized in that: on the described progressive die, mould assembly includes that top block, upper bolster, upper padding plate, train wheel bridge and the stripper plate from top to bottom set gradually, described progressive die lower mould assembly include bottom plate, bottom seat pad, die shoe, lower bolster and the lower bolster set gradually from the bottom to top;It is sequentially provided with the first punch extermal form punching station on the described progressive die between mould assembly and progressive die lower mould assembly, second draws job contract position, the 3rd punch extermal form punching station, the 4th punch extermal form station, 45 ° of stations of the 5th bending degree, the 6th bending station, heptalateral folding station, the 8th punching station, the 9th side punching station, the tenth shaping station, the 11st cut part station;The conveyer device transmitted at each station by workpiece it is additionally provided with between mould assembly and progressive die lower mould assembly on the described progressive die.
Described side folding station includes side and pushes and plugs cutter, back-moving spring, briquetting, it is that inclined-plane is arranged that described side pushes and plugs the cutter edge of a knife, described side pushes and plugs cutter and is provided with two on upper bolster, both sides push and plug the inclined-plane edge of a knife of cutter and are oppositely arranged, and it is separately positioned on workpiece both sides, described die shoe is provided with transversely movable two briquettings, the inclined-plane edge of a knife that the external port of described two briquettings pushes and plugs cutter respectively with both sides is corresponding, up and down during die holder pressing, side pushes and plugs cutter and briquetting can be driven to move extruding workpiece side folding, described briquetting connects back-moving spring, and between briquetting and die shoe, it is additionally provided with wearing plate.
Described upwards Bending Mould includes the molding lower punch and molding upper cavity die matched, and is provided with jigger pin in described molding upper cavity die, and molding lower punch is provided with interior de-.
The invention has the beneficial effects as follows the automobile rear backrest left plate progressive die after improvement, stage die is become the progressive die, and only takes up a punch press, be greatly improved production efficiency and saved cost.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in further detail.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the side folding station structure schematic diagram of the present invention.
Detailed description of the invention
Accompanying drawing illustrates the structure of the present invention, further illustrates it about details in conjunction with accompanying drawing below.This automobile rear backrest left plate progressive die, include and manufacture mould assembly and progressive die lower mould assembly on the progressive die of automobile rear backrest left plate corresponding construction, on the described progressive die, mould assembly includes top block 1, upper bolster 2, upper padding plate 3, train wheel bridge 4 and the stripper plate 5 from top to bottom set gradually, and described progressive die lower mould assembly includes bottom plate 6, bottom seat pad 7, die shoe 8, lower bolster 9 and the lower bolster 10 set gradually from the bottom to top;It is sequentially provided with the first punch extermal form punching station on the described progressive die between mould assembly and progressive die lower mould assembly, second draws job contract position, the 3rd punch extermal form punching station, the 4th punch extermal form station, 45 ° of stations of the 5th bending degree, the 6th bending station, heptalateral folding station, the 8th punching station, the 9th side punching station, the tenth shaping station, the 11st cut part station;The conveyer device transmitted at each station by workpiece it is additionally provided with between mould assembly and progressive die lower mould assembly on the described progressive die.Described conveyer device is motor-driven stock guide.
