Abstract
The utility model relates to the technical field of mechanical processing tools, and in particular relates to a bimetal saw blade comprising a saw blade body, wherein saw teeth are continuously arranged at the edge of one side of the saw blade body, the saw teeth comprise tooth top parts and tooth root parts, the tooth root parts and the saw blade body are of an integrated molding structure, the tooth top parts are fixedly connected on the tooth root parts by laser welding, the tooth top parts and the saw blade body are made of different metal materials, the hardness of the tooth top parts is HRC (rockwell hardness) 69-79 degrees, and the hardness of the saw blade body and the tooth root parts is HRC 42-43 degrees. In the bimetal saw blade, a mode of two metal combination welding is utilized so that the tooth top parts of the saw teeth have higher hardness, the cutting performance and the service life are improved, the cutting efficiency is greatly improved, the cutting quality is good, metal and other materials can be cut, the application scope is wide, the hardness of the saw blade body and the hardness of the saw teeth are different so as to ensure toughness of the saw blade body and ensure the saw teeth to have sufficiently high hardness at the same time, the processing is convenient, and the cost is low.
Description
Technical field:
The utility model relates to the machining tool technical field, refers in particular to bimetal saw blade.
Background technology:
Saw blade is widely used in a plurality of industries such as machine-building, Wood Processing, metallurgy, chemical industry, military project.Saw blade divides frame saw blade and bands for band again, and frame saw blade is not only thin but also long, Yi Bian the symmetry of hump is shaped on the saw of several sawtooth, this saw is installed in and carries out sawing workpieces on the buck saw lathe; Bands for band is not only thin but also long, one side the band saw that is shaped on several sawtooth of hump symmetry is installed in and carries out sawing work on the band saw lathe.
Existing saw blade is made up of the sawtooth of saw blade body, and in order to realize the better processability ability, the saw blade body requires to have high toughness; Sawtooth requires to have higher hardness, owing to receive the restriction of cost and toughness reguirements, saw blade is generally all processed by high-carbon steel; Improve hardness through the saw blade integral quenching, the hardness of saw blade integral body is all the same like this, so the sawtooth hardness of existing this saw blade is limited; Stock-removing efficiency is low, influences cutting quality, and service life is short; Be difficult to use in cutting metal material, restricted application.
The utility model content:
The purpose of the utility model is exactly to provide a kind of sawtooth hardness high bimetal saw blade to the deficiency of prior art existence.
To achieve these goals, the technical scheme that the utility model adopts is: bimetal saw blade, and it includes the saw blade body; One lateral edges of saw blade body is arranged with sawtooth continuously, and sawtooth includes crown portion and tooth root portion, tooth root portion and the saw blade body structure that is formed in one; Crown portion is fixedly connected in the tooth root portion through laser weld; Crown portion and saw blade body are the different metallic material, and the hardness of crown portion is HRC 68～79 degree, and the hardness of saw blade body and tooth root portion is HRC 42～43 degree.
The hardness of said crown portion is preferably HRC 72 degree, and the hardness of saw blade body and tooth root portion is preferably HRC 43 and spends.
The height of said sawtooth is 1/10～1/3 of a saw blade body width.
Said sawtooth left and right sides interlaced arrangement.
The material of said saw blade body, tooth root portion is spring steel or high carbon tool steel.
The material of said crown portion is a carbide alloy.
The utility model beneficial effect is: the utility model includes the saw blade body, and a lateral edges of saw blade body is arranged with sawtooth continuously, and sawtooth includes crown portion and tooth root portion; Tooth root portion and the saw blade body structure that is formed in one, crown portion is fixedly connected in the tooth root portion through laser weld, and crown portion and saw blade body are the different metallic material; The hardness of crown portion is HRC 68～79 degree, and the hardness of saw blade body and tooth root portion is HRC 42～43 degree, and the utility model utilizes the mode of two kinds of metallic combination welding; Make the crown portion of sawtooth have higher hardness, promote cutting ability and service life, increase substantially stock-removing efficiency; Cutting quality is good, can cutting metal and other material, and applied widely; The hardness of saw blade body and sawtooth is inequality simultaneously, in manufacture process, increases flexibility, not only guarantees the toughness of saw blade body but also guarantee that sawtooth has sufficiently high hardness; And easy to process, cost is low.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model sawtooth.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described; See that shown in Fig. 1～2, the utility model includes saw blade body 1, a lateral edges of saw blade body 1 is arranged with sawtooth 2 continuously; Sawtooth 2 includes crown portion 21 and tooth root portion 22; Tooth root portion 22 and saw blade body 1 structure that is formed in one, crown portion 21 is fixedly connected in the tooth root portion 22 through laser weld, and crown portion 21 is the different metallic material with saw blade body 1; The hardness of crown portion 21 is HRC68～79 degree, and the hardness of saw blade body 1 and tooth root portion 22 is HRC 42～43 degree.In this embodiment, the hardness of crown portion 21 is HRC 72 degree, and the hardness of saw blade body 1 and tooth root portion 22 is HRC 43 degree, not only guarantees the toughness of saw blade body 1 but also guarantee that sawtooth 2 has sufficiently high hardness.
The height of sawtooth 2 is 1/10～1/3 of saw blade body 1 width, and in this embodiment, the height of sawtooth 2 is 3mm, and the width of saw blade body 11 is 27mm, makes sawtooth 2 have mechanical property and cutting ability preferably.
Sawtooth 2 left and right sides interlaced arrangement, each tooth top tilt each other to the left and right, make sawtooth 2 undulate on saw blade body 1 arrange, and can obtain like this to make saw blade do not clamped by the material of sawing than the big slightly saw kerf of saw body thickness.
The material of saw blade body 1, tooth root portion 22 is spring steel or high carbon tool steel, has suitable hardness and toughness.The material of crown portion 21 is a carbide alloy, has higher hardness, can be used for cutting metal.
The utility model utilizes the mode of two kinds of metallic combination welding, makes the crown portion 21 of sawtooth 2 have higher hardness, promotes cutting ability and service life; Increase substantially stock-removing efficiency, cutting quality is good, can cutting metal and other material; Applied widely, the hardness of saw blade body 1 and sawtooth 2 is inequality simultaneously, in manufacture process, increases flexibility; Not only guarantee the toughness of saw blade body 1 but also guarantee that sawtooth 2 has sufficiently high hardness, and easy to process, cost is low.
Certainly, the above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
