Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Embodiment 1
See Fig. 1 and Fig. 2, basis is novel discloses a kind of tire grainer, and this grainer adopts metal plate-like structure, comprises integrated knife back portion 1, blade portion 2 and cutter tooth portion 3.
Knife back portion 1 adopts square platy structure, and the upper end of square platy structure is provided with manhole 4, and manhole 4 penetrates knife back portion 1, as suppending hole or the fixing hole in knife back portion 1.
The bottom in knife back portion 1 is the blade portion 2 of caving in, and blade portion 2 has multiple, and multiple blade portion 2 transverse row are distributed in the bottom in knife back portion 1, and the thickness of blade portion 2 successively decreases to lower end successively from upper end.Be provided with the intermediate supports portion 5 of outwardly convex between adjacent knife blades portion 2, the thickness in intermediate supports portion 5 increases from top to bottom successively, and the thickness in intermediate supports portion 5 is greater than the thickness in knife back portion 1.
The left and right sides of the bottom in knife back portion 1 is provided with left support portion 6 and right support portion 7, and left support portion 6 and right support portion 7 are relative to knife back portion 1 outwardly convex, and the consistency of thickness in left support portion 6 and right support portion 7 and intermediate supports portion 5.
The lower end of each blade portion 2 is provided with multiple cutter tooth portion 3, and the cross section in cutter tooth portion 3 is V-shaped, and the angle of v-shaped openings is 80 ° ~ 150 °, and the thickness of blade portion 2 successively decreases to lower end successively from upper end.The bottom in cutter tooth portion 3 is provided with cutter slope, and the angle of cutter slope and knife back portion 1 place vertical plane is 2 ° ~ 10 °, wherein, the angle of cutter slope and knife back portion 1 place vertical plane be 5 ° to cut capillary effect fruit best.
When using this grainer, blade portion 2 bottom of grainer is adjacent to surface of tyre, left support portion 6, right support portion 7 and intermediate supports portion 5 are aimed at respectively the decorative pattern groove at the tire left and right sides and middle part, then exerted a force by knife back portion 1, because the cutter slope, bottom in cutter tooth portion 3 has certain gradient, the power being applied to blade portion 2 is decomposed into cross shear and vertical pressure.Due in rubber hair lateral shear process, because left support portion 6, right support portion 7, intermediate supports portion 5 are bulge-structure, by this bulge-structure, blade portion is held up, and only contact with the rubber hair of rubber surface in cutter tooth portion 3, and the rubber hair of rubber surface is rejected.This grainer not only can the rubber hair of rejecting rubber surface of quickness and high efficiency, also can avoid surface of tyre scratch, reduce the scratch degree of tire.
Embodiment 2
The structure composition of the grainer of embodiment 2 forms substantially identical with the structure of the grainer of embodiment 1, and distinguishing characteristics is:
See Fig. 1 and Fig. 2, the blade portion 2 being arranged at bottom, knife back portion 1 has 2, be respectively left blade portion and right blade portion, between left blade portion and right blade portion, be provided with the intermediate supports portion 5 of outwardly convex, left blade portion and right blade portion symmetrical relative to intermediate supports portion 5.Left blade portion and right blade portion are equipped with 5 cutter tooth portions, and the angle of cutter tooth portion v-shaped openings is 100 °, and the angle of cutter slope and knife back portion 1 place vertical plane is 6 °.
It will be appreciated by those skilled in the art that, the thickness in the number in insert portion, intermediate supports portion, cutter tooth portion and blade portion, cutter tooth portion, intermediate supports portion, left support portion, right support portion can according to concrete surface of tyre texture structure setting, to meet different tyre model, improve and scrape capillary effect rate.
