[technical field]
The present invention relates to the instrument that a kind of automobile water wiper is scraped flake products, manufacture craft and is used for this technology.
[background technology]
The domestic automobile Wiper blade generally is made up of principal arm, middle arm and galianconism at present, combine and assemble between them generally in the following ways, 1, with rivet to each part rivet machine riveted, but in the riveted joint process, rivet two ends coat of metal and electrodeposited coating very easily are damaged; 2, directly the salient point on scraping blade principal arm, the middle arm is carried out crooked riveted with compression machine, this clinching method very easily destroys the sprayed coating of piece surface.More than two kinds of methods all can cause scraping blade product appearance defective and dimensional discrepancy, can produce gap and rocking during use, second-rate.
[summary of the invention]
In view of the problem that present known technology exists, the technical problem to be solved in the present invention is to be to provide a kind of to scrape that tablet quality is good, the automobile water wiper of appearance looks elegant is scraped flake products and the special tool of manufacture craft and this technology of enforcement.
For solving the problems of the technologies described above, the present invention takes following technical scheme to finish:
A kind of automobile water wiper scraping blade, comprise that the cross section is the principal arm of U type, middle arm, galianconism, be provided with the anti-attrition sheet between principal arm and middle arm, middle arm and the galianconism, and connect by pin, it is characterized in that: it is flat that described pin is arranged in the central part folder of galianconism or arm, measure-alike between the length dimension of the flat part of folder and cooresponding galianconism or middle arm U type structure inner side end in the middle of the pin.
A kind of technology of making above-mentioned automobile water wiper scraping blade, it is characterized in that: arm in the described scraping blade of at first the anti-attrition sheet being packed into, the anti-attrition sheet central authorities of again galianconism being packed into, pack into middle arm hole, anti-attrition film perforation, galianconism hole of described pin couples together three parts, press from both sides part in the middle of the pin that is positioned at described galianconism flat by special tool then, middle arm is connected with galianconism, measure-alike between the length dimension of part and galianconism U type structure inner side end in the middle of this pin; The same, being connected of principal arm and middle arm is that part in the middle of being arranged in pin measure-alike between arm and arm U type structure inner side end is pressed from both sides the flat riveted joint that realizes.
In addition, the present invention also provide implement above-mentioned technology special tool, it is characterized in that: this special tool comprises working clamp and wedge shape drift, working clamp comprises adapter plate, a left side that is symmetrical set, a right clamp and a left side, right spring bearing, left and right sides clamp is hinged with described adapter plate respectively, one end of clamp is a jaw, measure-alike between jaw size and described automobile water wiper scraping blade galianconism or middle arm U type structure inner side end, the other end outside of clamp contacts with the spring in being located at described spring bearing, the other end inboard of described clamp has the inclined-plane, and this inclined-plane is corresponding with the wedge surface of wedge shape drift.
The automobile water wiper that adopts technique scheme to finish is scraped flake products; part is pressed from both sides flat mode with each part connection of Wiper blade in the middle of adopting pin; because pin presss from both sides between flat span access location length size and cooresponding galianconism or middle arm U type structure inner side end measure-alike; connect the back like this and just can guarantee that the scraping blade scantling of structure is stable; can not produce the gap during use and rock; guaranteed to scrape tablet quality; in addition because pin presss from both sides flat part inside; scraping blade surface sprayed coating and pin two ends coat of metal just can be damaged scraping blade outward appearance better appearance in the flat process of folder.Compared with prior art, the present invention has outstanding substantive distinguishing features and obvious improvement.
