Description
Technical field
The utility model relates to a kind of process tool that is applicable to industry cutting, relates in particular to a kind of milling cutter, applicable to the cutting of processing metal, engineering plastics and fibrous composite, with raising working (machining) efficiency.
Background technology
Cutter is the instrument for machining in machine-building, claims again cutting element.Because most cutters is that machine is used, substantially all for cutting metal material, so " cutter " word is generally just interpreted as metal cutting tool.But material science development, various materials are also able to extensive use in the production of product and processing, as: engineering plastics and carbon fibre composite etc. (CN203401118U).Cutter can be divided into by the form of workpiece machining surface: cutter, aperture knife tool, threading tool, gear cutting tool and the cutting off tool etc. of processing various outer surfaces are several.
The component that milling is processed in field of machining is becoming more and more important, has progressively replaced to a certain extent other processing modes such as car, brill.Due to the extensive diversity of milling processing, except traditional metal material such as steel and cast iron, increasing novel metal/nonmetallic materials are also progressively included into the row of the machined material of milling processing, this is various metal alloys including aluminium-containing alloy not only wherein, the also various resin materials including high-grade engineering plastics, and various carbon fibre composite are in interior carbon fiber metal composite plate.
The material property of new material is all being much better than traditional material than various aspects such as, yield strength, specific heat capacity and fragility by force such as hardness, hot strength, matter, on the one hand can make the properties of product significantly improve, on the other hand also due to the ubiquitous chip breaking difficulty of these new materials, heat radiation is difficult, stickiness is large and fragility is large etc., and feature is that machining has been brought great difficulty.In reality processing, be often far longer than traditional material for the consumption of the milling cutter of processing novel material, even there is an extreme case that cutter only can be processed to tens workpiece.In such case, nearly nearly 30% the production cost of the producer is all for the consumption of cutter.As can be seen here, can the importance of milling cutter quality from this kind of processing mode saliency out, become and complete fast and efficiently milling processing, the key factor that reduces costs and increase the benefit.Milling cutter is a class for Milling Process, has the rotary cutter of one or more cutters tooth, is mainly used at processing plane, step, groove, profiled surface and cut-out workpiece etc.When work, each cutter tooth cuts the surplus of workpiece successively off and on.
For this reason, people have to cutting tool to redesign accordingly, so that cutting tool is adapted to the needs of new material processing.On the one hand, cutter life is extended, avoid tipping and fracture waiting the likely unexpected generation of defective work piece, to cut down finished cost; On the other hand, rhythm of production, efficiency and the product stability of machining are improved.
Start with from structure and the pattern of cutting tool, someone has proposed a kind of rake face wavy-edge milling cutter, and it as shown in Figure 1.Increase the overall length of Tool in Cutting blade by corrugated blade shape, thereby lower the operating pressure in cutting tip cutting edge unit are, and then tool life also can improve tool sharpening efficiency.Because the processing of rake face wave edge is very difficult, only have a few numerically controlled processing equipment to produce, not only it holds at high price, and has limited production in enormous quantities.Meanwhile, due to the rake face wave edge of general equipment after cannot reconditioning damaging, the maintenance of this class cutter often will be sent to China overseas, and not only the cycle is longer, and expensive.
On the basis of above-mentioned cutter, someone changes the rake face wave edge shown in Fig. 1 into rear knife face wave edge as shown in Figure 2, by wave edge being transferred to rear knife face, the production technology of simplifying to a certain extent, makes the equipment of nearly half left and right can complete the processing of this type of cutter.Rear knife face wave edge is divided into several narrower smear metals by original broadband smear metal, thereby has reduced cutting deformation, makes in milling process the curling and chip removal situation of the formation of smear metal be improved.Peripheral edge changes waveform into, causes very thin smear metal to rupture, and resistance to cutting decreases.Its defect is that machined surface can be roughness, and because cutting vibration is very large, coarse (fretting corrosion) easily appears in the junction surface of cutter and machine, is therefore difficult to be applicable to high precision machines.The particularly situation of dry cutting, because cutter is easy to have high heat, need to reduce cutting speed 10% to 20%, causes the decline of working (machining) efficiency.
Chinese utility model patent ZL200420018032.6 discloses a kind of Dual-body chopsticks milling cutter, and it also has similar blade pattern.The outer of milling cutter main body evenly offers three above unidirectional cutter grooves, in cutter groove, is welded with alloy cutter head, offers the M shape wave edge of a knife on alloy cutter head.This cutter is also similar has adopted the design of corrugated blade, and two milling cutters are coordinated to the processing for bamboo wood product.
