Abstract
The utility model relates to a kind of double end three sword hollow mjills, it comprises hollow milling handle (1), it is characterized in that the rear and front end of milling handle (1) is provided with milling head, milling head comprises two milling cutter swords (2), milling head is formed by the milling cutter idiosome machining of tubulose, milling cutter sword (2) offers three place's cutting edges, and cutting edge is curved edge, forms an arcwall face between two milling cutter swords (2).This double end three sword hollow mjills hydraulic cushion groove had for processing oblique layout can improve the advantage of working (machining) efficiency.
Description
Technical field
The utility model relates to a kind of double end three sword hollow mjills, belongs to groove Precision Machining cutter field.
Background technology
Have in engineering machinery hydraulic valve core part a kind of hydraulic cushion groove design (see A place in accompanying drawing 2), this groove be generally 45 degree of inclinations, mediate cylindrical and cannelure gap generally at 1 ~ 2mm, groove depth 1.5 ~ 3mm.Tradition processing mode employing diameter is the slotting cutter circular arc feeding milling of 1 ~ 2mm, and part and machine tool chief axis utilize tool locating to become 45 degree.This processing mode limits by tool diameter, and cutter life is very short, and it is longer to process pitch time, generally at 90 seconds grooves.There is no the dedicated tool processed for this type of groove both at home and abroad at present.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides double end three sword hollow mjills that a kind of hydraulic cushion groove for processing oblique layout can improve working (machining) efficiency.
The purpose of this utility model is achieved in that
A kind of double end three sword hollow mjills, it comprises hollow milling handle, the rear and front end of milling handle is provided with milling head, milling head comprises two milling cutter swords, milling head is formed by the milling cutter idiosome machining of tubulose, milling cutter sword offers three place's cutting edges, and cutting edge is curved edge, forms an arcwall face between two milling cutter swords.
Compared with prior art, the beneficial effects of the utility model are:
The utility model double end three sword hollow mjills are used for the cannelure of engineering machinery hydraulic valve core part can simultaneous manufacturing, a cannelure processing pitch time is in 30 seconds, compare traditional processing mode and can save 60 seconds, working (machining) efficiency improves about 60%.Double end three sword hollow mjill costs of manufacture are low, and cutter blank makes and sharpening all only needs common Digit Control Machine Tool and blade milling machine to process, and both-end design improves stock utilization.Therefore this double end three sword hollow mjills hydraulic cushion groove had for processing oblique layout can improve the advantage of working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model double end three sword hollow mjills.
Fig. 2 is the hydraulic cushion groove structural representation of hydraulic valve core part.
Wherein:
Milling handle 1
Milling cutter sword 2.
Detailed description of the invention
See Fig. 1, a kind of double end that the utility model relates to three sword hollow mjills, it comprises hollow milling handle 1, the rear and front end of milling handle 1 is provided with milling head, and milling head comprises two milling cutter swords 2, and milling head is formed by the milling cutter idiosome machining of tubulose, milling cutter sword 2 offers three place's cutting edges, cutting edge is curved edge, forms an arcwall face between two milling cutter swords 2, and three cutting edges process the groove bottom of cannelure, groove outer wall and groove inwall respectively.
The material of double end three sword hollow mjills adopts high-speed tool steel (W12Cr4V5Co5), and when adopting this double end three sword hollow mjills processing cannelures, time processing is shaping, and double end three sword hollow mjills are designed to two ends symmetry, improve stock utilization.
Double end three sword hollow mjill production methods: first carry out cutter blank fine finishining, carry out vacuum hardening and three the high temperature anneal, then carry out sharpening after fine finishining.It is shaping that sharpening presses accompanying drawing 1 sharpening.The utility model adopts circumferencial direction only to open two milling cutter swords, ensures the intensity of each cutting edge, improves cutter life.
