Specific embodiment
As shown in Figure 1, the present invention is a kind of suitable for there is the no waste mine process for stamping of press-bending operation, comprising the following steps: 1) Each side press two convex buds in billot, convex bud is located at the common edge of two parts, 2) by wherein at least one product shape Profile is gone out and the both ends position Tu Bao is made not cut off two parts of holding and connected by convex bud, and 3) convex bud is flattened so that two productions The distance between product become larger, 4) junction of two parts of cutting and by two adjacent parts bend in reverse direction part at Type.The part or product are fuel tank bandage.
The present invention is first punched out printing to part by design of part requirement on billot before step 1) and (goes out hole simultaneously Print appearance profile).
As shown in figs. 2-9, a kind of no waste mine stamping progressive die with forming process of the present invention, including body 1, body On be arranged successively and be provided with punching printing mechanism 4, Ya Bao mechanism 5, product shape profile punching mechanism 6, convex bud and clap 7 and of mechanism Cutting mechanism 8 is bent, the grading conveying mechanism of billot is additionally provided on the body, and (the grading conveying mechanism of billot is that common mechanism is such as set The delivery wheel mechanism on upper and lower mould is set, is not shown in the figure, for billot 10 on delivery wheel, delivery wheel rotates band under power drive Billot 10 on dynamic delivery wheel is run).
The Ya Bao mechanism 5 is formed from pressing luxuriant punch-pin 5.1 and with the pressure bud cavity plate 5.2 with luxuriant punch-pin 5.1 is pressed;Outside product Shape profile punching mechanism 6 is made of trimming punch 6.1 and trim die 6.2, and there is oblique angle 6.3 at 6.1 both ends of trimming punch;Press-bending is cut Breaking mechanism 8 bends punch-pin 8.1 and upwards press-bending cavity plate by a pair of punch-pin 8.1 and upward cavity plate 8.2(that bends that bends upwards upwards 8.2 have mutually matched upward oblique angle) and it is a pair of bend punch-pin 8.3 downwards and bend downwards cavity plate 8.4(bend downwards it is convex Mould 8.3 and downwards press-bending cavity plate 8.4 are with mutually matched downward oblique angle) composition.
The luxuriant punch-pin 5.1 of the pressure, trim die 6.2, upwards press-bending cavity plate 8.2 and the downward cavity plate 8.4 that bends are arranged same In one lower die 3;The luxuriant cavity plate 5.2 of the pressure, trimming punch 6.1, the curved mould 8.1 of upward belling and press-bending punch-pin 8.2 setting downwards In the same upper mold 2.
In order to keep billot operation smooth, stripper 9 is equipped between the upper mold 2 and lower die 1, upper mold 2 is equipped with spring catch (elastic cylindrical pin), stripper is fixed on spring catch.Stripper 9 is equipped with evacuation punching printing mechanism 4, Ya Bao mechanism 5, produces Product appearance profile punching mechanism 6, convex bud clap mechanism 7 and bend cutting mechanism 8 notch, to be connected to rushing in upper mold 2 Hole printing mechanism 4 presses luxuriant punch-pin 5.1, trim die 6.2, bends cavity plate 8.2 upwards and bends cavity plate 8.4 etc. downwards to pass through and unload Flitch realizes its function.Wherein Ya Bao mechanism 5 can also be the stripper mold insert 5.1 being embedded on stripper 9.
The present invention is as shown in Figure 1, OP10 punching printing process carries out part by design of part requirement on billot first Punching printing;OP20 process each side presses two convex buds in billot, and convex bud is located at the common edge of two parts;OP30 work Sequence sky step;One of product shape profile is gone out (both ends are not cut off locally) by OP40 process, and OP50 process flattens bud, by Billot can be elongated after bud flattens, to the distance between two products be pulled open, when OP60 process is cut off separation and bent There are certain distance between two parts, will not rubs mutually, achieve the purpose that improve product quality requirement.
After the present invention presses luxuriant punch-pin 5.1 when in use and presses luxuriant cavity plate 5.2 that billot is pressed bud upwards, billot 10 continues forward It is moved to OP40 trimming process, trimming punch 6.1 and trim die 6.2 cut out the appearance profile of one of product, and trimming is convex There is oblique angle 6.3 at mould both ends, cut product shape largely, only stay both ends connection not separate, when billot moves forward to OP50 Stripper mold insert 5.1 claps the convex bud of technique on billot 10, to the distance between two products be pulled open, in OP60 process Punch-pin 8.1 is bent upwards and bends cavity plate 8.2 upwards and bends punch-pin 8.3 downwards and bend cavity plate 8.4 downwards, and product is bent When two products 11 will not rubs mutually, bend Angular Dimension and stablize, surface quality of workpieces is good.
Inventive die can once go out two parts, and luxuriant (or beading), postorder are first pressed in material strip appropriate location by work step in front Luxuriant (or muscle) is flattened before part forming, so that the distance between two parts be pulled open, makes part forming angle stabilization.
It is provided by the invention to be suitable for having the no waste mine stamping die of press-bending operation and process for stamping, billot grading with billot Conveying mechanism automatic running and punch forming are generated without friction iron filings in whole process, and product does not have padding, product surface quality It is good, angle stabilization is bent, once multiple parts out, substantially increases production efficiency.Especially suitable for having press-bending operation No waste mine punching press.
