The step 5 blanking is cut edge: the bright wisp body that step 4 is finished is placed in the diel, and by hydraulic punching machine bright wisp body base and curve are cut edge, make the cross-sectional width of curve greater than the cross-sectional width of base portion after the side cut, and cross-sectional width become large by the junction of base portion and curve gradually to curve;
The step 6 punch forming: after the side cut with the upper side edge of bright wisp body and lower side through forming upper overturning and lower flange after the to the inside turnover after the punch forming, form end cap after the termination punch forming turnover with base portion and with the right flange of termination punch forming of curve;
The punching end of the die-cut and base portion of step 7 breach: the termination of bright wisp body base and the termination of curve are placed on the stamping die of end, and by punch press the punching end of curve are gone out breach and the waste material unnecessary to the punching end of base portion;
Step 8 polishing: by automatic polishing machine the outer mold surface of bright wisp body is polished, by manual polishing machine the two ends of bright wisp body are polished;
The step 9 anodization: the bright wisp body that step 8 is made carries out anodization;
The step 10 group is vertical: the outer mold surface on the bright wisp body is sticked protective film, and at the inboard corresponding rib of bright wisp body the locating fastener pedestal is installed, and pastes whole foam again;
Step 11 test package: test by cubing, pack after the check.
Compared with prior art, the invention has the advantages that whole rear corner window luminous strip is one-body molded, manufacture method is simple, improved output and qualification rate, reduced productive costs, produced bright wisp surface smoothing, good corrosion resistance, and fastness is good after installing with vehicle body, and reliable in quality has increased the whole structure of automobile appearance.

The specific embodiment
Below be specific embodiments of the invention and by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
Among the figure, body 1; Base portion 11; Curve 12; Upper overturning 2; Lower flange 3; Rib 4; Block button base 5; End cap 6; Breach 7; Foam 8; Protective film 9; Egative film 10.
Extremely shown in Figure 10 such as Fig. 1, this rear corner window luminous strip comprises body 1, body 1 mainly is comprised of the base portion 11 in left side and curve 12 one on right side, curve 12 relative base portion 11 tendencies are crooked, the cross-sectional width of curve 12 is greater than the cross-sectional width of base portion 11, and cross-sectional width becomes large by the junction of base portion 11 and curve 12 gradually to curve 12.
The upper side edge of body 1 and lower side form upper overturning 2 and lower flange 3 after to the inside turnover.
Be provided with on the inboard of described body 1 for the rib 4 that block button base 5 is installed, be separately installed with block button base 5 at corresponding rib 4; Block button base 5 at curve 12 is equipped with the egative film 10 that cooperates usefulness with block button base; Be provided with the end cap 6 that is bent to form to the inside on the termination of described base portion 11; Be provided with breach 7 on the termination of curve 12; The angle of the tendency bending of curve 12 relative base portions 11 is 15 °~35 °.
Be pasted with whole foam 8 on the inboard of described body 1, foam 8 first is set here is in order conveniently to install, the 2nd, guarantee the leak tightness after bright wisp is installed.
Be coated with protective film 9 on the outer mold surface of described bright wisp body 1; The manufactured materials of described bright wisp body 1 is the aluminium section bar material;
A kind of manufacture method of rear corner window luminous strip may further comprise the steps:
Step 1 is extruded: extrude the strip shape bright wisp body 1 that cross-sectional width equates by extrusion die, two continuous ribs 4 are contained in the inboard of the body 1 of extruding here;
Step 2 is crooked: the bright wisp body 1 that step 1 is extruded is placed on the bending die and cooperates excellent power mucilage binding to join tool, by bending machine bright wisp body 1 is carried out bending, makes bright wisp body 1 form base portion 11 and curve 12; As shown in Figure 9, dotted portion is crooked part;
Step 3 muscle milling: by the milling tool fixedly behind the bright wisp body 1, and by high-speed milling machine bright wisp body 1 inboard unnecessary rib 4 is milled pin, only keep the rib 4 of block button base 5 location usefulness;
Step 4 is removed the milling burr: remove the milling burr with cutter, and blow off burr and chip with air gun, wipe clean bright wisp body 1 with clean rag at last;
The step 5 blanking is cut edge: the bright wisp body 1 that step 4 is finished is placed in the diel, and by hydraulic punching machine bright wisp body 1 base portion 11 and curve 12 are cut edge, make the cross-sectional width of curve 12 greater than the cross-sectional width of base portion 11 after the side cut, and cross-sectional width become large by the junction of base portion 11 and curve 12 gradually to curve 12; As shown in figure 10, dotted portion is the part of cutting away;
The step 6 punch forming: after the side cut with the upper side edge of bright wisp body 1 and lower side through forming upper overturning 2 and lower flange 3 after the to the inside turnover after the punch forming, form end cap 6 after the termination punch forming turnover with base portion 11 and with the right flange of termination punch forming of curve 12;
The punching end of the die-cut and base portion 11 of step 7 breach 7: the termination of bright wisp body 1 base portion 11 and the termination of curve 12 are placed on the stamping die of end, and by punch press the punching end of curve 12 are gone out breach 7 and the waste material unnecessary to the punching end of base portion 11;
Step 8 polishing: by automatic polishing machine the outer mold surface of bright wisp body 1 is polished, by manual polishing machine the two ends of bright wisp body 1 are polished;
The step 9 anodization: the bright wisp body 1 that step 8 is made carries out anodization;
The step 10 group is vertical: the outer mold surface on bright wisp body 1 is sticked protective film 9, and at bright wisp body 1 inboard corresponding rib 4 locating fastener pedestal 5 is installed, and pastes whole foam 8 again; Have six block button bases 5;
Step 11 test package: test by cubing, pack after the check.
Bright wisp body 1 weight of producing after top step is lighter, and has better elastic strength and pulling strengrth.
Here the order that it is emphasized that above step can not be changed, as bending is carried out in first milling, milling again, like this owing to the stress of the bright wisp body 1 after milling, milling owing to self changes, can cause produced product nonconformity, and be easy to the milling of the rib 4 that should not cut away in milling, milling, cause waste of material.
Specific embodiment described herein only is to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or replenish or adopt similar mode to substitute described specific embodiment, but can't depart from the defined scope of spirit of the present invention.
