Abstract
The utility model provides a special mechanical clamp variable-position face milling cutter for machining martensitic stainless steel, and relates to a special mechanical clamped cutting tool. A retainer ring (3) is sleeved outside a cutting tool body (1) and the upper surface of the retainer ring (3) leans against a sloping bench shoulder end face (1-1) of the cutting tool body (1), and the retainer ring (3) is fixedly arranged on the cutting tool body (1); cutter blade components (4) are distributed on the cutting tool body (1) along the circumferential direction and the angles between the two adjacent cutter blade components (4) are unequal. Through the development and the use of the utility model, the special mechanical clamped cutting tool improves the cutting efficiency of the cutter tool by 80-200 percent compared with the original standard cutting tool, prolongs the service life by one time, is stable in the surface machining quality of the parts finish machining to reach Ra6.3-3.2 micrometers, and lowers the comprehensive machining cost by 60-100 percent compared with the original standard cutting tool.
Description
Technical field
The utility model relates to a kind of special-purpose mechanical clamped cutting tool of processing martensitic stain less steel.
Background technology
The turbine blade material mostly is martensitic stain less steel (as 1Cr13,2Cr13,0Cr17N4Cu4Nb etc.) greatly, and this material belongs to difficult-to-machine material, and cutting ability is very poor, brings very big difficulty to machining.Martensitic stain less steel elevated temperature strength height, work hardening tendency is big, thermal conductivity factor is little, and the bonding phenomenon causes very seriously processing that stock-removing efficiency is low, cutter life short, quality is difficult for guaranteeing during existing cutting tool processing vapor turbine blade.
The utility model content
The utility model provides a kind of processing martensitic stain less steel special-purpose indexable surface milling cutter, and the bonding phenomenon causes very seriously processing that stock-removing efficiency is low, cutter life short when solving existing cutting tool processing vapor turbine blade, quality is difficult for the problem that guarantees.
The utility model is made up of cutter hub, soket head cap screw, back-up ring and blade assembly, and shield ring sleeve leans on the bevelled shoulder end face of cutter hub mutually in the outside of cutter hub and the upper surface of back-up ring, and back-up ring is packed on the cutter hub; The blade assembly edge circumferentially is distributed on the cutter hub and the angle between adjacent two blade assemblies does not wait.
The utlity model has following beneficial effect: by the research and development of this cutter, use, Tool in Cutting efficient is more former to improve 80%～200% times with standard cutter, life-span is improved 1 times, stable Ra6.3～3.2 μ the m that reach of Finishing Parts Machining suface processing quality, the comprehensive process cost is more former to reduce by 60%～100% with standard cutter.
Description of drawings
Fig. 1 is an overall structure half sectional view of the present utility model, Fig. 2 be the A of Fig. 1 to view, Fig. 3 is the angle schematic diagram of blade.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, present embodiment is made up of cutter hub 1, soket head cap screw 2, back-up ring 3 and blade assembly 4, back-up ring 3 is enclosed within the outside of cutter hub 1 and the upper surface of back-up ring 3 leans on mutually with the bevelled shoulder end face 1-1 of cutter hub 1, and back-up ring 3 is packed on the cutter hub 1 by soket head cap screw 2; Blade assembly 4 edges circumferentially are distributed on the cutter hub 1 and the angle between adjacent two blade assemblies 4 does not wait.This cutter is the suit pattern, after each part clamping assembling, makes circumference beat with the amesdial inspection and be not more than 0.06mm that end face run-out is not more than 0.03mm.Present embodiment is mainly used in steam turbine, and the facing cut of stainless steel blade parts such as the hydraulic turbine is thick, fine finishining.
The specific embodiment two: present embodiment is described in conjunction with Fig. 1 and Fig. 2, the difference of the present embodiment and the specific embodiment one is: the blade assembly 4 in the present embodiment is made up of briquetting 5, blade 6 and positive and negative bolt 7, blade 6 is packed in by briquetting 5 and positive and negative bolt 7 in the cutter groove 1-2 of cutter hub 1, the true rake γ of blade 6 when cutter uses
0=9 °, relief angle α
0=7 °.That the positive and negative bolt that adopts during the briquetting clamping blade occurs in the time of can eliminating with general bolt clamping blade because the gap that screw and screw produce, and the loosening phenomenon of blade that occurs when cutter is used have so just guaranteed the stablizing of Tool in Cutting, reliability; For adapting to the milling to martensite stainless steel material, anterior angle must increase by more conventional cutter, so existing transferred to the blade relief of determining is big than standard insert.The material trademark that blade adopts is carbide alloy M2, SM35 or YS2T.
The specific embodiment three: in conjunction with Fig. 1 and Fig. 2 present embodiment is described, the difference of the present embodiment and the specific embodiment one is: cutter hub 1 is provided with chip pocket 1-3 in the present embodiment, and described chip pocket 1-3 places a side of blade 6.Can produce a lot of metal fillings when cutter turns round, chip pocket is used to hold the metal fillings of discharge.
