Abstract

The utility model discloses a kind of radial direction scraper, including cutter head and knife bar, it is characterised in that：The cutter head includes scraping blade surface, rake face and rear knife face, and the rear knife face and scraping blade surface are arcwall face, and the scraping blade surface intersects with rake face forms the first cutting edge；The scraping blade surface intersects with rear knife face forms the second cutting edge, and the knife bar is equipped with transition face, which connects with rake face, and the distance of first cutting edge away from cutter head vertex is more than distance of second cutting edge away from cutter head vertex.

Description

A kind of radial direction scraper

Technical field

The utility model is related to a kind of cutters, particularly a kind of radial direction scraper.

Background technology

It needs to process arc groove on phone housing, the groove face requirement unusual light of arc groove, we are typically to use before Ball knife is processed, and ball knife milling is not only slow but also the finish of slot that processes does not reach requirement also, thus we devise one Scraper is planted to meet new requirement.

The content of the invention

For overcome the deficiencies in the prior art, the utility model provides a kind of radial direction scraper.

Technical solution is used by the utility model solves its technical problem：

A kind of radial direction scraper, including cutter head and knife bar, it is characterised in that：The cutter head include scraping blade surface, rake face and Knife face afterwards, the rear knife face and scraping blade surface are arcwall face, and the scraping blade surface intersects with rake face forms the first cutting edge； The scraping blade surface intersects with rear knife face forms the second cutting edge, and the knife bar is equipped with transition face, the transition face and rake face Connect, the distance of first cutting edge away from cutter head vertex is more than distance of second cutting edge away from cutter head vertex.

The knife bar is equipped with positioning surface, which connects with transition face.

Knife face includes knife face after major first flank and second after described.

The cutter head both sides are equipped with inclined avoidance face.

The beneficial effects of the utility model are：This cutter is processed by skiving blade in face of phone housing, knife during processing Have motionless, phone housing movement, the first cutting edge first touches phone housing, machine away the metal of upper strata certain depth, leave Some allowance, scraping is remaining again needs to cut away metal for subsequent scraping blade surface, and scraping blade surface can not only realize scraping Purpose, and scraping blade surface can also squeeze metal during scraping, make it close smooth, polished by the second cutting edge, So as to obtain the very high arc groove of finish, the above process is once completed, and not only meets the requirement of best bright finish, but also It is efficient.

Description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is the topology view of the utility model；

Fig. 2 is the bottom view of the utility model.

Specific embodiment

With reference to Fig. 1, Fig. 2, the utility model discloses a kind of radial direction scrapers, and including cutter head 1 and knife bar 2, the cutter head 1 wraps Scraping blade surface 3, rake face 4 and rear knife face are included, the rear knife face and scraping blade surface 3 are arcwall face, and the scraping blade surface 3 is with before Knife face 4 is intersecting to form the first cutting edge 5；The scraping blade surface 3 intersects with rear knife face forms the second cutting edge 6, so as to which first cuts 5 and second cutting edge 6 of sword is cut as arc, thus can just scrape the slot of arc, the knife bar 2 is equipped with transition face 7, passes through transition Face 7 can play the function of chip removal, and can be to avoid reducing cutter head 1 the problem of can avoid stress concentration by transition face 7 Intensity, which connects with rake face 4, and distance of first cutting edge 5 away from 1 vertex of cutter head is more than the second cutting edge 6 Distance away from 1 vertex of cutter head, such scraping blade surface 3 are an inclined cambered surface, and ability work in-process plays scraping and squeezes metal Purpose.

As shown in the figure, the knife bar 2 is equipped with positioning surface 8, which connects with transition face 7, determines before facilitating processing Position.

Knife face includes knife face 10 after major first flank 9 and second after described.In said structure, continuous multiple rear knife faces are set Low-angle relief angle is gently dropped to from the relief angle of wide-angle in respect of profit, not only can guarantee that cutter head 1 has enough intensity, but also can reduce and cut The friction between sword and machined surface is cut, prevents from generating heat, so as to effectively in raising cutting precision.

1 both sides of cutter head are equipped with inclined avoidance face 11, can so be touched to avoid other positions of work in-process cutter head 1 To machined surface.

A kind of radial direction scraper provided above the utility model embodiment, is described in detail, used herein Specific case is set forth the principle and embodiment of the utility model, and the explanation of above example is only intended to help Understand the method and its core concept of the utility model；Meanwhile for those of ordinary skill in the art, according to the utility model Thought, there will be changes in specific embodiments and applications, in conclusion this specification content should not be understood For the limitation to the utility model.
