Abstract
The utility model relates to a tremble-preventing metal saw which comprises a disk type cutter body with sawtooth-shaped grooves, wherein an alloy tool bit is arranged on the cutter body. The tremble-preventing metal saw is characterized in that an opening groove is formed in one surface of the cutter body at each of the bottoms of the more than three sawtooth-shaped grooves along the direction of a center line, and the more than three opening grooves are uniformly formed in one surface of the cutter body. According to the tremble-preventing metal saw disclosed by the utility model, as the opening grooves which are uniformly formed are formed in one surface of the cutter body at each of the bottoms of the sawtooth-shaped grooves, the metal saw during cutting has small elastic deformation, releases internal stress generated by non-uniform cutting stress of the cutter body and eliminates tremble of the cutter body, so that the tool bit has the tremble-preventing processing capacity, solves the problem that an existing metal saw trembles in processing, reduces the processing resistance, lowers the abrasion of a cutting edge and prevents resonance, tool blockage and tool breaking phenomena generated in the processing. Therefore, not only is the processing precision improved and is the cutting speed of the product increased, but also the waste on raw materials caused by product rejection rate is greatly reduced.
Description
Technical field
The utility model belongs to metal material cutting tool technical field, particularly relates to a kind of vibration-resistant metal saw.
Background technology
In metal material cutting field, cutting-tool engineering and Machining Technology for Cutting means are all round the continuous exploration practice of this target of cutter efficient low-consume development and perfection.Cutting power and the effect of metal material cutting tool in actual cut process, directly impact processes the quality of product and the qualification rate of product.
Current known metal saw is to non-ferrous metal, when the material such as red copper or stainless steel workpiece carries out the disposable machining completing, no matter carry out climb cutting processing or upmilling processing, cutter is all subject to the impact of cutting resistance in working angles, simultaneously cutting edge shape and surface of the work profile agrees with degree deficiency, make cutter hub at cutting point place unbalance stress, cause cutter hub to produce the processing resistance that trembles and cause, blade wearing and tearing, processing resonance, swaging clamp and the phenomenon of forging a knife, impact not only the machining accuracy of product, reduced cutting speed, and increased the percent defective of product, cause raw-material waste.
Summary of the invention
The utility model provides the machining accuracy of product of making high for solving the technical problem existing in known technology, production efficiency is high, and product percent defective is low, reduces raw-material waste, significantly reduces a kind of vibration-resistant metal saw of product processing cost.
The technical scheme that the utility model adopts is:
A vibration-resistant metal saw, comprises that periphery is uniformly distributed the disc-shaped cutter hub of several serrated slot, in each serrated slot, is welded with alloy cutter head, and all the blade on alloy cutter head is same direction clockwise or is same direction counterclockwise along center line along center line; Be characterized in: the cutter hub one side along more than three trench bottom of serrated slot is respectively shaped with an open slot along centerline direction, described three above open slots are evenly distributed on cutter hub one side along center line.
The utility model can also adopt following technical scheme:
Described open slot is circle hook open slot, and bill direction and the blade on described alloy cutter head of described round hook open slot are same direction;
Described round hook open slot is three, along center line 120 degree, is evenly distributed on cutter hub.
Described open slot is narrowed down by wide gradually from position to the bill end direction being connected with serrated slot.
Described cutter hub is 42CrMo material.
Described cutter head is YT class alloy material.
Advantage and the good effect that the utlity model has are:
1, the utility model adopts on metal saw along the cutter hub one side of the trench bottom of serrated slot and is shaped with uniform open slot along centerline direction, during cutting, milling cutter has had small elastic deformation, discharged the internal stress that cutter hub produces because of cutting unbalance stress, eliminated trembling of cutter hub, make cutter possess the antidetonation working ability of quivering, solved the problem that metal saw processing is trembled, reduced processing resistance, the wearing and tearing of blade have been reduced, prevented from adding the resonance that produce man-hour, swaging clamp and the phenomenon of forging a knife, raising not only machining accuracy and the cutting speed of product, and significantly reduced and caused raw-material waste because of product percent defective.
2, the utility model is by making open slot round hook open slot, in the disposable process that completes machining of particularly non-ferrous metal being carried out to cutting-in ratio is greater than four to one groove depths as materials such as red copper and stainless steels, effectively avoided the phenomenon that resistance increases, blade weares and teares, processes resonance, swaging clamp and forge a knife of trembling and causing due to cutter hub, improved the antidetonation of cutter in the cutting process ability of quivering, good stability in cutting process, cut laborsaving, the service life of having improved operating efficiency and cutter.
3, the utility model is by by being distributed on cutter hub of circle hook open slot trisection, and its shock resistance and deep trouth and so on processing effect particularly highlights, and Product Precision and the working (machining) efficiency made are all greatly improved.
4, the utility model circle vibration-resistant metal saw make simple, easy to use, safe and reliable, improve and gradual perfection the technical merit of cutter, Milling Process technology and product processes level.
