Abstract
The utility model provides a machine presss from both sides formula carbide multiple -cutting -edge scraper, it relates to a multiple -cutting -edge scraper. The utility model discloses an in order to solve whole high -speed steel sheet metal scraper, not only scrape the inefficiency, the scraper is not durable moreover, the number of times of refacing is many, influences machining efficiency's technical problem. A machine presss from both sides formula carbide multiple -cutting -edge scraper, includes blade, cutter arbor and extension bar, the cutter arbor rear end face is equipped with the screw hole along the axis, the extension bar front end passes through screw hole threaded connection with the cutter arbor, and the cutter arbor external diameter equals with the extension bar external diameter, is connected with the cutter arbor through holding screw in the blade insertion groove. The utility model discloses owing to adopt carbide tool, improved scraping machining efficiency greatly, machining efficiency improves more than 50%, the blade has the scraping blade, but the transposition use many times, only need more renew behind the blade abraded blade can, avoided the wholly situation of scrapping of cutter, practiced thrift the cutter expense.

Description
Technical field
This utility model relates to a kind of multiple-cutting-edge scraper.
Background technology
Gland sealing gear is one of steam-turbine unit parts, and profile is thin slice segmental arc, requires to be assemblied on corresponding components of steam turbine according to different packings.Low pressure (LP) cylinder endoporus assembling gland sealing gear due to assembling after gland sealing gear endoporus have 0.05-0.1mm surplus, when need to assemble, pincers worker craft scraping is fallen, and uses overall high-speed steel thin plate scraper in the past, and not only scraping efficiency is low, and scraper is not durable, refaces often, affects working (machining) efficiency.
Utility model content
The purpose of this utility model is that not only scraping efficiency is low, and scraper is not durable, refaces often, affects the technical problem of working (machining) efficiency in order to solve overall high-speed steel thin plate scraper, it is provided that a kind of clip type hard alloy multiple-cutting-edge scraper.
A kind of clip type hard alloy multiple-cutting-edge scraper, including blade, knife bar and extension bar, described knife bar rear end face is provided with screwed hole along axis, described knife bar is provided with groove along axis, the width of groove is h, circumferentially surface, described knife bar front portion is provided with upper recess surface and concave surface, upper recess surface and concave surface are arranged with groove Parallel Symmetric, knife bar front portion is provided with through upper recess surface, the screw hole of concave surface and groove, described blade is circumferentially provided with several gap, the angular aperture of gap is β degree, described angular aperture is with diameter for symmetrical angle, gap bottom surface is inclined-plane, blade relief is α, the thickness of described blade is s, threadeded by screwed hole with knife bar in described extension bar front end, knife bar external diameter is equal with extension bar external diameter, blade insertion groove is connected with knife bar by holding screw.
The height h of described groove is more than s.
Described blade is circumferentially provided with several gap.
Described blade is circumferentially provided with 3-6 gap.
The angular aperture β of described gap is 45 degree.
Described blade relief α is 20 degree.
Described blade thickness s is 2mm.
For low pressure (LP) cylinder gland sealing gear endoporus shaving action situation, for improving shaving action efficiency and scraper service life, clip type hard alloy multiple-cutting-edge scraper of the present utility model, this scraper is machine holding carbide alloy blade pattern, owing to adopting carbide tool, substantially increases shaving action efficiency, working (machining) efficiency improves more than 50%, blade has scraping cutting edge, and indexable use repeatedly, saves the non-cutting time of scraper edge of refacing in a large number.Owing to adopting mechanical clamped cutting blade pattern, after blade abrasion, only need to more renew blade, it is to avoid cutter entirety scraps situation, has saved cutter expense.
