Abstract
The utility model discloses an unequal pitch reamer with a large cutting edge dip-angle, which is used for metal-cutting hole machining, particularly for reaming machining of deep holes and intermittent holes of alloy manganese steel materials. The geometry and the angle of the cutting edge of the reamer are greatly improved for increasing the finish and the geometrical accuracy of the reaming hole machining.
Description
The utility model relates to a kind of big cutting edge inclination and does not wait the tooth pitch reamer, is used for the ream processing in metal cutting processing, the particularly deep hole of alloy manganese steel material and interrupted hole.
When approaching the surplus machining, usually adopt the reamer fraising.Existing reamer is when processing alloy material large diameter, deep borehole or interrupted hole, geometric accuracy occurring can not guarantee, there is the operating mode of vertically straight trace in the low and hole wall of fineness, according to prior art data-searching, though multiple modified reamer is arranged, does not have big cutting edge inclination not wait tooth pitch type reamer.
The purpose of this utility model is, provides a kind of cutting ability stable, and the mechanical strength height also can guarantee a kind of reamer of its fraising processing fineness and geometric accuracy for the special alloy material.This reamer also can be worked under the situation of processing working condition difference, and equipment is not had special requirement.
The utility model is achieved in that the cutting edge inclination of reamer cutting edge is 15 °.The tooth pitch of each cutting edge is on the circular section that is not equally distributed on reamer.The improvement of this angle and geometry to reamer is to make to be processed of chip-flowing, guarantees the fineness of machined surface effectively, and eliminates the residual straight trace of hole wall behind the ream.
The utility model reamer can use on all kinds of Metal Cutting Machine Tools or other special-purpose reaming apparatus.Compare with existing reamer, guarantee and improved the fineness and the geometric accuracy of hole processing.Compare with common reamer, its manufacturing process is uncomplicated.
Shown in the Figure of description 1, be the profile front view of reamer, the cutting edge inclination of reamer cutting edge is 15 °.Fig. 2 is the B-B cutaway view, and the tooth pitch that marks each cutting edge is on the circular section that is not equally distributed on reamer.It is the partial enlarged drawing shape of profile of tooth that Fig. 3 A amplifies.
The material of the utility model reamer is high-speed steel or tool steel, quenching hardness: blade is HRC63-65, and shank is HRC38-48. Reamer is made by following process: 1, blanking; 2, beat the two ends centre bore; 3, the rough turn cylindrical in two ends, top stays the mill amount; 4, tooth punching (by Fig. 2 distribution form) stays the mill position; 5, processing caudal peduncle; 6, marking; 7, heat treatment; 8, grind the two ends centre bore; 9, each size of cylindrical grinding puts in place; 10, finish cutting edge fine finishining (pressing Fig. 3 profile of tooth) at the multipurpose instrument (tool) mill.
In above-mentioned process, in the time of should noting on the milling machine tooth punching, not equally spaced calibration. When the number of teeth is 8 among Fig. 2, ω1＝41°53′，ω
2＝44°05′；ω
3＝46°06′；ω
4=47 ° 56 '. The number of teeth is 6 o'clock ω1＝58°02′；ω
2＝59°53′；ω
3=62 ° 05 '. The number of teeth can also be 10 and 12. The each several part physical dimension of reamer changes with the size of its diameter.
Claims (4)
1, a kind of big cutting edge inclination does not wait the tooth pitch reamer, is used for metal cutting processing, and the particularly ream of alloy manganese steel material hole processing is characterized in that:
A, described reamer are big cutting edge inclinations
The tooth of b, described each cutting edge of reamer is and is not equally distributed on the reamer circular section.
2, reamer according to claim 1 is characterized in that: big cutting edge inclination and equally spaced the combination not.
3, reamer according to claim 1 is characterized in that: the manufactured materials of reamer adopts high-speed steel or tool steel.
4, according to claim 1 or 2 or 3 described reamers, it is characterized in that: cutting edge inclination is 15 °, and its number of teeth is divided into four kinds in 6,8,10,12 teeth according to the difference of diameter.
