Abstract
The utility model relates to a metallurgical saw blade, in particular to a metal cold-and-hot cutting circular saw blade. The metal cold-and-hot cutting circular saw blade comprises a saw blade main body, wherein flat-top sawteeth are distributed at the outer edge of the saw blade main body; the saw blade main body and the flat-top sawteeth adopt an integrally one-step formed structure; and sawtooth tips integrated with the flat-top sawteeth are formed at the tops of the flat-top sawteeth through laser cladding. The tooth tips adopting clad hardened structures have very high bonding strength, and can adapt to the requirement for high-speed saw-cutting of workpieces; after being used once, the saw blade can be reused once ground so long as the flat-top parts are subject to cladding forming, and the external diameter of the saw blade keeps stably unchanged; the saw blade main body and the tooth tips can be made of different alloy materials to achieve different performances; if the saw blade main body adopts a low-carbon or an ultra-low-carbon design, together with appropriate alloying measures and heat treatment, the saw blade main body has favorable ductility and toughness, shock resistance and moderate strength; and if the tooth tips adopt high-alloy composite designs, the superhard and wear-resistant cutting edges can be manufactured and the single-pass service life of the saw blade is prolonged.
Description
Technical field
The utility model relates to metallurgical saw, specifically is a kind of cold and hot metal cutting circular saw blade.
Background technology
At metallurgy industry, cold and hot metal cutting circular saw blade is all used in sawing end to end, the scale sawing of tube, rod section material.The conventional metals cold hot cut circular saw blade is a kind of, and to be that blade body and crown are whole adopt identical steel plate materials, through mechanical Milling Process moulding, and obtains different hardness by different Technologies for Heating Processing.Though crown portion obtains high rigidity through quenching, and limited by steel plate materials, alloying element wherein is less, belongs to carbon steel substantially, wears no resistance, fragility is big.Especially metallurgy industry production scene condition is more abominable, and saw blade always bears bigger impact in sawing process, and sawtooth is easy to interrupt, and service life is lower.Another kind of cold and hot metal cutting circular saw blade is a welding sawtooth blank on blade body, passes through sharpening moulding sawtooth then.Because welding sawtooth blank process is many, and saw blade intensity and hardness are reduced, and more can influence saw blade performance when repeating to weld.Welding sawtooth blank needs special-purpose high-frequency induction welder, and too much welding process has obviously increased energy consumption.In addition, sawtooth is by the moulding of monoblock blank sharpening, and sawtooth blank volume is relatively large, can increase the cost of alloy sawtooth, and is all the more so when especially using the higher alloy material of price.
The utility model content
The utility model is intended to solve conventional metals cold hot cut circular saw blade poor performance, service life is low, manufacturing cost is high problem, and a kind of have better repeat performance, longer comprehensive service life, lower sawing cost, the cold and hot metal cutting circular saw blade of energy-saving material-saving are provided.
The technical scheme that the described problem that solves the utility model adopts is:
A kind of cold and hot metal cutting circular saw blade, comprise blade body, described blade body outer rim is distributed with the flat-top sawtooth, and blade body and flat-top sawtooth are the integral one-step molding structure, and the sawtooth crown that combines together with it is arranged by laser cladding forming at described flat-top sawtooth top.
Compared with prior art, the cold and hot metal cutting circular saw blade that the technical program provides, because the sawtooth crown is the cladding hardening structure, therefore, the lamellar body that blade body peace top saw tooth constitutes can adopt different alloy materials with the sawtooth crown, to realize different performance.For example, lamellar body can adopt low-carbon (LC), the design of Ultra-low carbon composition, is equipped with suitable alloying measure, after Overheating Treatment, has good plasticity and toughness, impact resistance, moderate intensity, can prolong the access times of saw blade greatly, strengthen recycling chance, improve the security of sawing.The sawtooth crown can adopt high alloy, the design of compound composition, makes superhardization, anti abrasive cutting edge, reaches to prolong the saw blade single purpose in service life.The sawtooth crown fuses through metallurgical mode and flat-top sawtooth top of merging, has very high bonding strength, the needs that can adapt to the high speed sawing workpieces, after saw blade uses once, only need can use after cladding forming, the reconditioning once more at the flat-top position, the outside dimension of saw blade can keep stable and not diminish.
Description of drawings
Fig. 1 is the local blade bodies planar structure schematic diagram that amplifies of the utility model.
Fig. 2 is the local blade bodies perspective view of amplifying of the utility model.
Among the figure: blade body 1, flat-top sawtooth 2, sawtooth crown 3.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, and purpose only is to understand better the utility model content.Therefore, illustrated embodiment does not limit protection domain of the present utility model.
Referring to Fig. 1, Fig. 2, the cold and hot metal cutting circular saw blade that present embodiment is following, its blade body 1 is a disk (diameter can be Ф 800mm-Ф 2500mm) that the center is with holes, the disk periphery is distributed with a plurality of flat-top sawtooth 2, blade body 1 adopts the low-alloy steel integral one-step molding of Ultra-low carbon of the same race or low-carbon (LC) to become blade bodies with flat-top sawtooth 2, by adjusting phosphorus content and trace alloying element, can effectively improve metallographic structure, the plasticity and toughness of blade bodies, and can produce performance by the comprehensive mechanical performance and the cracking resistance line that quench, the tempering acquisition is good.At flat-top sawtooth 2 tops, by laser cladding forming the sawtooth crown 3 that combines together with flat-top sawtooth 2 is arranged, laser melting coating be heat energy by laser with metal or alloy powder cladding forming at flat-top sawtooth 2 tops.After the 3 basic configuration moulding of sawtooth crown, re-use special saw blade gear grinding machine sharpening and go out the sawtooth cutting edge.Sawtooth crown 3 can adopt dystectic hard carbide, thereby sawtooth crown 3 wearabilities are significantly increased, and can reach the above hardness of 50HRC, makes saw blade have the good sawing life-span.
The metallurgical melting that forms between described superhard sawtooth crown 3 of present embodiment and the blade bodies connects, and is very firm, can satisfy the needs of various sawing operating modes.In order to adapt to the sawing requirement of different workpieces, the sawtooth number of teeth, flute profile can be designed to various forms, but tooth pitch is generally between 9-25 millimeters; Blade body 1 can be a slab construction, also can use the sideshake structure.
