Description
[technical field]
The invention relates to a kind of stamping procedure of automobile sealed lid.
[background technology]
Current automobile sealed lid, is generally the shapes being gone out some regulations by punch press, then takes away and carry out fine finishining, but a lot of shape of these seal covers all needs to take away, lathe or milling machine carry out finishing operation, like this its processing cost is just higher, consuming time longer, wastes more manpower.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art and provide a kind of processing simple, the stamping procedure of low, the consuming time few automobile sealed lid of cost.
For above-mentioned purpose, the present invention by the following technical solutions:
A stamping procedure for automobile sealed lid, is characterized in that comprising the steps:
A, blanking, go out the sheet metal of specification toroidal on a metal plate;
B, stretching, utilize punch press to be stretched by sheet metal, by stretched for the middle part of a sheet metal boss top, makes sheet metal form a hat-shaped;
C, punching, carry out punching by the position, boss top of sheet metal;
D, flange, after having rushed hole in the position on boss top, also had a bending edges edge, by this bending edges along carrying out flange, having made the vertical shape of this bending edges, making 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 again on the inwall of annular Dun Bi, this oil groove is communicated with the upper surface of Dun Bi and the lower surface of sheet metal;
G, rush method cap bore, evenly stamp out multiple through hole at sheet metal outer shroud surrounded surface.
The stamping procedure of a kind of automobile sealed lid as above, is characterized in that between above-mentioned D step and E step, also has shaping step, carries out compression and thickening, drawn high by the height of annular Dun Bi more afterwards, make pier thick also corresponding thinning by thick for the pier of annular Dun Bi.
The stamping procedure of a kind of automobile sealed lid as above, is characterized in that in described step B, stretches and is divided into three operations to stretch, make form of metal process steady.
The stamping procedure of a kind of automobile sealed lid as above, is characterized in that, in described G step, after having rushed method cap bore, then method cap bore being carried out shaping and Hole chamfering.
Beneficial effect of the present invention has:
The present invention utilizes punch press sheet metal to be struck out successively the shape of regulation, particularly punching press F step rush oil groove, never occurred before this step, and it is stamping to rush this step one step of oil groove, save the plenty of time that milling machine of taking away carries out milling oil groove, cost greatly reduces.
Generally speaking, it is simple that this case has processing, low, the consuming time advantage such as few of cost.

[detailed description of the invention]
Below in conjunction with accompanying drawing and embodiment, the present invention is elaborated:
As shown in the figure, a kind of stamping procedure of automobile sealed lid, comprises and 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, stretching, utilize punch press to be stretched by sheet metal, by stretched for the middle part of a sheet metal boss top, makes sheet metal form a hat-shaped.This better more gently realizes stretching, and in this step, stretches and is divided into three operations to stretch, and make form of metal process steady, punching press effect is better.As in Figure 2-4.
C, punching, punching is carried out in 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, the aperture due to punching has been less than the external diameter on boss top, therefore also has a bending edges edge, by this bending edges along carrying out flange, making the vertical shape of this bending edges, making 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 again on the inwall of annular Dun Bi, this oil groove is communicated with the upper surface of Dun Bi and the lower surface of sheet metal; Because existing oil groove is all adopt the mode of milling machine to mill out to come, this processing mode cost is high, long processing time.And adopt now impact style to carry out processing oil groove, still can reach required precision, and cost is low, shortens process time, save manpower.As shown in Figure 10.
G, rush method cap bore, evenly stamp out multiple through hole at sheet metal outer shroud surrounded surface.In general, after having rushed 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 have shaping step, carry out compression and thickening by thick for the pier of annular Dun Bi, again the height of annular Dun Bi is drawn high afterwards, make pier thick also corresponding thinning.It is more than the whole automobile sealed process covered at punch press.
In addition, this case additionally provides the die assembly of this automobile sealed lid of processing, specific as follows:
The die assembly of processing automobile seal cover, includes cope match-plate pattern 1 and lower bolster 2, and lower bolster 2 is arranged in sequence with many group bed dies 3.Each bed die 3 described all has different die cavitys 4, and be arranged in sequence with to organize the mold 5 matched with bed die 3 at the lower surface of cope match-plate pattern 1, each mold 5 all has different die heads more.Described cope match-plate pattern 1 is connected with actuator and drives it to move down and make the die head of each mold 5 enter the die cavity 4 of bed die 3 thus realize the processing of seal cover.During the maximum feature of this die assembly, multiple diel is arranged in a template, utilize actuator unified driving cope match-plate pattern, the unification of multiple molds 5 of cope match-plate pattern is moved to the bed die 3 on lower bolster, and different moulds has different die cavitys 4 and die head, the punching press simultaneously of multiple operation can be realized like this, one-off, can complete the punching press of multiple operation, and efficiency is very high, cost is low, saves time.In the present embodiment, each bed die 3, mold 5 form the mould getting up to be formed and are respectively step mould in stamped metal die, drawing die, punching die, flanging die, pier, rush oil groove mould, rush method cap bore mould, shaping mould etc.As shown in figure 13.
In general, the number of described bed die 3, mold 5 is 8-12.Can arrange according to the needs of manufacturing procedure.
