Description
[technical field]
The present invention is the stamping procedure about a kind of automobile sealed lid.
[background technology]
Current automobile sealed lid, goes out shapes of some regulations, then takes away and carry out polish generally by punch press, but these seal and cover a lot of shapes and be required for taking away lathe or milling machine carries out finishing operation, like this its processing cost is the highest, the most longer, wastes more manpower.
[summary of the invention]
It is an object of the invention to overcome the deficiencies in the prior art to provide a kind of processing simple, low cost, the stamping procedure of the fewest automobile sealed lid.
For above-mentioned purpose, the present invention by the following technical solutions:
The stamping procedure of a kind of automobile sealed lid, it is characterised in that comprise the steps:
A, blanking, go out the sheet metal of specification toroidal on a metal plate；
B, drawing, utilize punch press that sheet metal is carried out drawing, and the middle part drawing of sheet metal is gone out a boss top, makes sheet metal form a hat-shaped；
C, punching, be punched out the position, boss top of sheet metal；
D, flange, after having rushed hole in the position on boss top, an also bending edges edge, by this bending edges along carrying out flange, make the vertical shape of this bending edges, make boss top form an annular Dun Bi；
Step in E, pier, utilizes punch press that the inwall of annular Dun Bi is gone out a stairstepping step；
F, rush oil groove, utilize punch press to go out an oil groove, the upper surface of this oil groove connection Dun Bi and the lower surface of sheet metal on the inwall of annular Dun Bi again；
G, rush method cap bore, uniformly stamp out multiple through hole at sheet metal outer shroud surrounded surface.
The stamping procedure of a kind of automobile sealed lid as above, it is characterised in that between above-mentioned D step and E step, also shaping step, the pier thickness of annular Dun Bi is carried out compression and thickening, the most again the height of annular Dun Bi is drawn high so that pier thickness is the most thinning.
The stamping procedure of a kind of automobile sealed lid as above, it is characterised in that in described step B, drawing is divided into three operations to carry out drawing so that form of metal process is steady.
The stamping procedure of a kind of automobile sealed lid as above, it is characterised in that in described G step, after punching method cap bore, then method cap bore is carried out shaping and Hole chamfering.
Beneficial effects of the present invention has:
The present invention utilizes punch press that sheet metal strikes out the shape of regulation successively, particularly punching press F step rush oil groove, the step for before never occurred, and it is stamping to rush this step one step of oil groove, saving milling machine of taking away and carry out the plenty of time of milling oil groove, cost is greatly lowered.
Generally speaking, it is simple that this case has processing, low cost, the time-consuming advantage such as few.

[detailed description of the invention]
With embodiment, the present invention is elaborated below in conjunction with the accompanying drawings:
As it can be seen, the stamping procedure of a kind of automobile sealed lid, including comprising the steps:
A, blanking, go out the sheet metal of specification toroidal on a metal plate；The diameter of this sheet metal, can set as required, and stamped sheet metal utilizes one of them diel.As shown in Figure 1.
B, drawing, utilize punch press that sheet metal is carried out drawing, and the middle part drawing of sheet metal is gone out a boss top, makes sheet metal form a hat-shaped.This more preferably more gently realizes drawing, and in this step, drawing is divided into three operations to carry out drawing so that form of metal process is steady, and punching press effect is better.As in Figure 2-4.
C, punching, be punched out the position, boss top of sheet metal, and the aperture of punching is less than the external diameter on boss top.As shown in Figure 5.
D, flange, after having rushed hole in the position on boss top, owing to the aperture of punching is less than the external diameter on boss top, therefore an also bending edges edge, by this bending edges along carrying out flange, make the vertical shape of this bending edges, make boss top form an annular Dun Bi.As shown in Figure 6.
Step in E, pier, utilizes punch press that the inwall of annular Dun Bi is gone out a stairstepping step.As Figure 7-9.
F, rush oil groove, utilize punch press to go out an oil groove, the upper surface of this oil groove connection Dun Bi and the lower surface of sheet metal on the inwall of annular Dun Bi again；Being all that the mode using milling machine mills out due to existing oil groove, this processing mode cost is high, long processing time.And use now impact style to carry out processing oil groove, still can reach required precision, and low cost, shorten process time, save manpower.As shown in Figure 10.
G, rush method cap bore, uniformly stamp out multiple through hole at sheet metal outer shroud surrounded surface.In general, after punching method cap bore, then method cap bore is carried out shaping and Hole chamfering.As depicted in figs. 11-12.
Between above-mentioned D step and E step, also shaping step, the pier thickness of annular Dun Bi is carried out compression and thickening, the most again the height of annular Dun Bi is drawn high so that pier thickness is the most thinning.It is above whole automobile sealed covering the course of processing at punch press.
Additionally, this case additionally provides the die assembly processing this automobile sealed lid, specific as follows:
Process the die assembly of automobile sealed lid, include cope match-plate pattern 1 and lower bolster 2, lower bolster 2 is arranged in sequence with many group lower mold 3.Each lower mold 3 described is respectively provided with different die cavitys 4, and the lower surface at cope match-plate pattern 1 is arranged in sequence with organizes the mold 5 matched with lower mold 3 more, and each mold 5 is respectively provided with different die heads.Described cope match-plate pattern 1 connects the die cavity 4 of the die head entrance lower mold 3 having actuator to drive it to move down and to make each mold 5 thus realizes sealing the processing of lid.During the maximum feature of this die assembly, multiple diels are arranged in a template, utilize actuator unified driving cope match-plate pattern, make the unified lower mold 3 on lower bolster of multiple molds 5 of cope match-plate pattern move, and different moulds has different die cavitys 4 and die head, so can realize the punching press simultaneously of multiple operation, one-off, can complete the punching press of multiple operation, and efficiency is the highest, low cost, time-consuming.In the present embodiment, each lower mold 3, mold 5 composition get up step mould in mould respectively stamped metal die, cupping tool, punching die, flanging die, the pier formed, rush oil groove mould, rush method cap bore mould, shaping mould etc..As shown in figure 13.
In general, described lower mold 3, the number of mold 5 are 8-12.Can arrange according to the needs of manufacturing procedure.
