Abstract
The invention aims to disclose a left-handed rose reamer which can improve a chip discharging effect so as to reduce a temperature generated in the machining process, thereby prolonging the service life of a tool and saving use cost of a client. The left-handed rose reamer disclosed by the invention comprises a handle part and a blade part; the blade part is provided with a chip discharge groove; the left-handed rose reamer has the key point that the chip discharge groove is in a left-handed form. In the machining process, the rotating direction of the chip discharge groove is opposite to that of the tool, and thus, chips generated by the blade part can move towards the direction of the end part of the blade part along the chip discharge groove and are ground by the end part of the blade part so as to be discharged along a gap between the blade part and the inner wall of a drilled hole without being accumulated at a rabbet of the chip discharge groove like chips generated by a conventional right-handed rose reamer.
Description
Technical field
The invention belongs to cutter manufacturing technology field, specially refer to a kind of left-handed rose reamer.
Background technology
Rose reamer, as an important component part in cutter for machining, is mainly used in the orifice chamfer processing in hole.Along with the development of machinery industry, user is to having proposed requirements at the higher level delivery date of the crudy of product, process reliability, working (machining) efficiency, cutter etc.The rose reamer of traditional design is taked dextrorotatory form, and when high-speed cutting, the chip removal effect of cutter is poor, and iron filings can not arranged, and causes adding the temperature producing man-hour and can fall, and tipping phenomenon easily appears in cutter.
Summary of the invention
The object of the invention is to propose a kind of left-handed rose reamer, can improve chip removal effect, thereby reduce, add the temperature that produce man-hour, thereby the life-span of improving cutter is saved client's use cost.
Left-handed rose reamer of the present invention comprises shank and blade, and described blade is provided with chip area, and key is that described chip area is levorotatory form.
In process, because the direction of rotation of chip area is contrary with the direction of rotation of cutter, therefore the chip that blade produces can move by the end direction along chip area to blade, and pulverized by the end of blade, thereby along the gap between blade and drill hole inner wall, discharge, and can not accumulate in like that to traditional dextrorotation rose reamer the notch place of chip area.
Further, described chip area side is provided with auxiliary chip area, and described auxiliary chip area is parallel to chip area, and the area of section of auxiliary chip area is increased to shank direction gradually by blade.Auxiliary chip area is set to up big and down small version, can promote further chip and move to blade direction.
Left-handed rose reamer of the present invention is taked the chip area of levorotatory form, has improved the chip removal effect that adds man-hour, makes to add the temperature producing man-hour and greatly reduces, and has improved cutter life.

Accompanying drawing explanation
Fig. 1 is the structural representation of the left-handed rose reamer of the present invention.

The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle etc.
Embodiment:
As shown in Figure 1, the left-handed rose reamer of left-handed rose reamer of the present embodiment comprises shank 1 and blade 2, and described blade 2 is provided with chip area 3, and key is that described chip area 3 is levorotatory form.
In process, because the direction of rotation of chip area 3 is contrary with the direction of rotation of cutter, therefore the chip that blade 2 produces can move by the end direction along chip area 3 to blade 2, and pulverized by the end of blade 2, thereby along the gap between blade 2 and drill hole inner wall, discharge, and can not accumulate in like that to traditional dextrorotation rose reamer the notch place of chip area 3.
Further, described chip area 3 sides are provided with auxiliary chip area 4, and described auxiliary chip area 4 is parallel to chip area 3, and the area of section of auxiliary chip area 4 is increased to shank 1 direction gradually by blade 2.Auxiliary chip area 4 is set to up big and down small version, can promote further chip and move to blade 2 directions.
Claims (2)
1. a moulding rose reamer, comprises shank and blade, and described blade is provided with chip area, it is characterized in that described chip area is levorotatory form.
2. left-handed rose reamer according to claim 1, is characterized in that described chip area side is provided with auxiliary chip area, and described auxiliary chip area is parallel to chip area, and the area of section of auxiliary chip area is increased to shank direction gradually by blade.
