For the external ornament of automobile, the filler rod classes that form by stainless steel sheet that adopt more.
Such as, around the window of the side of automobile, shown in the image pattern 2 like that, window frame filler rod 1, water Qie Chemen filler rod 2, assembly filler rod 3 etc. are installed, form appearance design.
The window frame filler rod be shown in the image pattern 3 (along the section end view drawing of the A-A line among Fig. 2) like that, be installed on the filler rod on the external appearance design surface of doorframe, has following problem, promptly, by rolling formation, drawing, the cross sectional shape of formation regulation and curved shape etc., but at the stainless steel sheet place, albefaction, aesthetic property variation take place in crooked bigger position.
Also is same in such albinism than the R of macrobending portion in the water Qie Chemen filler rod shown in Fig. 4 (along the section end view drawing of the B-B line among Fig. 2).
In combination filler rod shown in Figure 2, more situation is to adopt stainless-steel sheet to make blank, carries out drawing, still, has following problem, that is, in roll plate, generally in spiral (coil) material, there is the roll-in eye, position that laterally cuts out on the edge and the position that longitudinally cuts out, the direction difference of roll-in eye, like this, the outward appearance of appearance design face is inhomogeneous.
In addition, when drawing, in order to prevent scar, pasting protective tapes, still, be difficult to prevent scar fully, knock vestige, is one of reason that constitutes bad generation.
So, in the past,, polish for scar and the albefaction of revising appearance design face, still, the color intensity of the part after the polishing and other part have taken place do not matched, maybe will be attached to the situation of the resin component damage on the filler rod.
In addition, occasion at the blank that adopts the elongate member as water Qie Chemen filler rod, window frame filler rod, be generally rolling formation, the parts of bight ornamental trimming, the parts that make up the such weak point of filler rod, 3D shape are generally by drawing, if manufacturing process difference, the fine limit work that then also has appearance design is also different, the problem of the unitarity variation of appearance design.
The gloss that the corrosion-resistant steel filler rod also has when making is strong, but be exposed under the wind and rain environment during, the problem that gloss reduces.

Summary of the invention
The present invention the object of the present invention is to provide a kind of insertion strip for cars in view of the aforementioned technical background, wherein, as automobile integral body, the homogeneity height of the appearance design of corrosion-resistant steel filler rod, filler rod integral body has the one sense, has controlled metallic luster.
Technical essential of the present invention relates to a kind of insertion strip for cars, it is characterized in that by form trickle jog on the surface of the corrosion-resistant steel filler rod blank of drawing or rolling formation the metallic luster of stainless steel material being controlled.
Also can carry out sand-blast finish or electrolytic polishing to the corrosion-resistant steel filler rod blank of drawing or rolling formation and handle, form trickle jog from the teeth outwards.
Because of drawing or rolling formation, the crooked big part of corrosion-resistant steel filler rod blank produces albefaction, but by forming trickle jog from the teeth outwards, this albefaction part is unshowy, forms uniform outward appearance.
Also can after sand-blast finish, adopt the acidic liquid of sulfuric acid, nitrose to carry out the pickling on surface as required, or carry out chemical grinding processing, electrolytic polishing processing.
Size by trickle jog suppresses metallic luster, as required, carries out chemical grinding processing, electrolytic polishing processing, can improve reflectivity, the metallic luster of control corrosion-resistant steel filler rod blank.
If on the corrosion-resistant steel filler rod blank of drawing or rolling formation, handle by sand-blast finish or electrolytic polishing, form trickle jog, then obvious, the scattering of the light by this jog, the albefaction of curve is not eye-catching, and is finish-machined to the tone of the satin weave sense that suppresses metallic luster.
Here, the tone of satin weave sense refers to be also referred to as the tone that the metallic luster of " satin sense " is suppressed.
After corrosion-resistant steel was carried out drawing, rolling formation, as the mode that forms trickle jog from the teeth outwards, the sand-blast finish price was low, can be fit to adopt the shotblasting machine of the various shot-peenings that utilize sandblast, glass bead, resin balls, SUS ball, Ceramic Balls etc.
In the thin occasion of filler rod plate thickness, inside and outside two the face sides projection shot-peening at filler rod can prevent the distortion of filler rod thus.
If adopt glass bead, the so lower material of hardness of resin balls as shot-peening, then can form trickle jog at the state that is left metallic luster morely, polish fine limit work on the whole.
In insertion strip for cars, by resin component being adhered on the corrosion-resistant steel filler rod blank, or on corrosion-resistant steel filler rod core, push the occasion that engages resin according to complex method, also adopt the mode that on stainless drawing blank, engages resin component by injection moulding widely.
But the compound filler rod of these stainless steel sheets and resin component is as-is condition also, carries out sand-blast finish or electrolytic polishing.
But, with the occasion of the composite members of resin component, the shot-peening material can adopt the material of the softness of glass bead, resin balls etc., the situation that resin component does not exceedingly destroy is for well.
In addition,, then in the shot-peening material of the material of softness, resin component is not caused scar, can only stainless steel parts be finish-machined to the satin weave sense if adopt the resin component of soft resin.
In mode as the trickle jog of formation on corrosion-resistant steel filler rod blank, carry out the occasion that electrolytic polishing is handled, and by behind shot-ball peening, carrying out the occasion that electrolytic polishing is handled, controlled tone thus, if stainless steel sheet adopts ferrite steel plate (product that is equivalent to JES Japan Engineering Standards SUS430), then the control of tone is easy, obtains the outward appearance that the level and smooth soft gloss by the satin weave sense forms.
In addition, handle if carry out electrolytic polishing, owing to be formed at the lip-deep fire coat thickening of stainless steel sheet, so corrosion stability also improves.
If adopting stainless steel sheet, after carrying out rolling formation, by the Compound Extrusion method, engage the corrosion-resistant steel filler rod blank of soft resin component, and after carrying out drawing, pass through injection moulding, engage on the corrosion-resistant steel filler rod blank of soft resin component, adopt glass bead, resin balls is carried out sand-blast finish, then resin component is not caused scar, the tone on the surface of may command stainless steel, this point is illustrated in front, but, adopting stainless steel sheet, carry out the occasion of rolling formation and carry out sand-blast finish, engage the method for resin component afterwards by compound extruding method, and in the occasion that similarly adopts stainless steel sheet and carry out drawing, if carry out sand-blast finish,, engage resin component then by injection moulding, then be formed at the lip-deep trickle jog of corrosion-resistant steel blank, resin material can closely bond by physics mode, and the bind strength of corrosion-resistant steel and resin component improves, and the tone of may command stainless steel.
In addition, also have the straight line material after pressure roller and the extrusion molding is carried out satin weave sense processing, carry out the situation of bending step then.
In insertion strip for cars of the present invention, because after the employing stainless steel sheet carries out drawing or rolling formation, by sand-blast finish or the trickle jog of electrolytic polishing processing formation from the teeth outwards, so the albefaction of section curve etc. is not eye-catching, specious property is even, even in the insertion strip for cars with rolling formation product and the combination of drawing product, the single-piece homogeneity is still higher like this.
In addition, because the strike vestige, the scar that produce in the manufacturing process when drawing etc. are not eye-catching yet, so the fraction defective reduction.
If sand-blast finish is carried out on the surface to stainless steel sheet, then obtain the appearance design that the soft gloss by the satin weave sense forms, thus, automobile is whole to obtain new appearance design.
Also have, by reducing the shot-peening pressure of sand-blast finish, or the low shot-peening of selected hardness, then can carry out the polishing fine limit work of kish gloss.
If polish fine limit work, then reflected light is double, has the degree of depth.
By the surface being controlled at soft tone, the companion that wind and rain causes also alleviates over time.
In the occasion of design vehicle with filler rod, in the past, the position that section curve R is little must be from outer setting in eye-catching position, or increase curve R, still, according to the present invention, because the curve of less R can be set in the outward appearance design surface, Design freedom increases.
In addition, the surface that also has a filler rod that has carried out sand-blast finish is difficult to adhere to the effect of the dirt of fingerprint etc.
So resin film in the past, the occasion of coating have the problem of the durability of peeling off easily, still, durability of the present invention also improves greatly.
