The utility model is also based on the manufacture method providing a kind of lid of road lamp of road lamp above.Specifically refer to Figure 20.

Figure 20 is the flow chart of the manufacture method of the lid of a kind of road lamp that the utility model embodiment provides.Wherein, in order to more convenient understanding, the present embodiment will combine the preparation method of lower cover citing description the present embodiment that embodiment above provides.As shown in figure 20, the manufacture method of the lid of road lamp of the present utility model comprises the following steps:

Step S1 a: sheet metal is provided.

Concrete, transport tape provides a sheet metal, and the material of this sheet metal can be copper, aluminium or its alloy.

Step S2: length direction the is being positioned at sheet metal central authorities first area along the width of sheet metal along sheet metal stamps out the first punching press pattern successively, on the second area being positioned at both sides, first area, stamp out the second punching press pattern successively simultaneously, and punching press number of times is counted.

Wherein, the first punching press pattern is different from the second punching press pattern.First area such as can as the lower cover diapire of lower cover, and second area such as can as the lower cover sidewall of lower cover.

In this step, the punching press of the first punching press pattern and the second punching press pattern can successively be carried out also can carrying out simultaneously, specifically determines according to the particular location of the first punching press pattern and the second punching press pattern.

Step S3: after the count value of punching press number of times meets the punching press threshold value according to the expection length setting of lid, stops punching press, and intercepts the part metals sheet material of punching press from sheet metal.

Wherein, before stopping punching press, length direction along sheet metal carries out at least twice punching press respectively on first area and second area, to form the first punching press pattern array formed by least two group first punching press patterns in first area, and form the second punching press pattern array formed by least two group second punching press patterns at second area.

Wherein, the part first punching press pattern in the first punching press pattern array is different from other the first punching press patterns, or the part second punching press pattern in the second punching press pattern array is different from other the second punching press patterns.Such as the first punching press pattern and the second punching press pattern are respectively the installing blind of lower cover, any one or the combination of installing in through hole, wire rod through hole, thermal vias and accommodating recess.

Wherein, after punching press stops, the part metals sheet material of the punching press of intercepting is taken off from transport tape.

Step S4: relative to the first area bending second area of the part metals sheet material of punching press, carry out formation lid.

In this step, first obtain the part metals sheet material taken off from transport tape.Then this sheet metal is bent.

Wherein, second area is divided into the first subregion and the second subregion that the width along sheet metal arranges, and wherein the first subregion is near first area.Wherein, the first subregion can be such as sidewall body, and the second subregion can be such as side wall extension.

In this step, be specially and the first subregion is bent into vertical with first area, and the second subregion is bent into is parallel to first area and extends towards each other.

Therefore, in the present embodiment, by completing all punching press programs to sheet metal on a transport tape, relative to the scheme completing punching press in prior art on different transport tapes, the scheme of this enforcement is simpler, convenient, saves time.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
