Abstract

The present invention relates to a kind of NEW TYPE OF COMPOSITE burnishing-in knife, ream sword and burnishing-in sword integrated design.Based on this burnishing-in knife unique design, process unstable when effectively can solve to process high-accuracy hole, it is insufficient that manufacturing procedure complexity and production efficiency are low etc..

Description

A kind of NEW TYPE OF COMPOSITE burnishing-in knife
Technical field
The present invention is a kind of burnishing-in knife, is related to high-accuracy hole machined design on part, is suitable for precision hole machining field.
Background technique
When the high-accuracy hole of existing tool sharpening, the processes such as some is cut with scissors, finish reamed by reaming, slightly are realized；Passing through also is thick It cuts with scissors, finish ream, the processes such as burnishing-in are realized.The above method all has same shortcoming: processing is unstable, and manufacturing procedure is complicated, Production efficiency is low and cost of charp tool height etc..
Summary of the invention
To overcome above-mentioned deficiency, the present invention provides a kind of NEW TYPE OF COMPOSITE burnishing-in knife.
Technical scheme is as follows:
Such as Fig. 1, cutting edge 1 is made of ream sword 1-1 and burnishing-in sword 1-2；Latter section of burnishing-in sword 1-2 diameter D2Than the last period 1- 6mm ream sword 1-1 diameter D1Big 0.01~0.06mm.
The beneficial effects of the present invention are: its feature one: cutting edge is made of ream sword and burnishing-in sword two parts, in processing essence Close Kong Shike semifinishing, the synchronous progress of Precision Machining, not only can once complete precision hole machining, but also can save the unstable work of multiple tracks Sequence, to greatly improve production efficiency and processing stability；Its feature two: latter section of burnishing-in sword diameter D2Than the last period 1-6mm Ream sword diameter D1Big 0.01~0.06mm, when processing inner bore of part, PRECISION HOLE is formed by material plasticity deformable squeeze, because And the intensity on inner bore of part surface is improved greatly.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 cutter main view；Fig. 2 .A-A cross-sectional view；Fig. 3 .B-B cross-sectional view；
In Fig. 1: 1. cutting edges, 1-1. ream sword, 1-2. burnishing-in sword, 2. necks, 3. shanks
Specific embodiment
As shown in Fig. 1, Fig. 2 and Fig. 3
Cutting edge 1 is made of ream sword 1-1 and burnishing-in sword 1-22；Latter section of burnishing-in sword 1-2 diameter D2Than the last period 1-6mm ream Sword 1-1 diameter D1Big 0.01~0.06mm.
