Description
Technical field
The utility model relates to a kind of parting tool, particularly relates to a kind of metal circular saw.
Background technology
Metal cold hot-cutting saw blade is the one of metal circular saw, the parting tool that iron and steel enterprise is conventional, saw blade material commonly uses the trade mark 45Mn2V, 50Mn2V, 65Mn, 75Cr1,8CrV etc., thermohardening, at 200-350 degree Celsius, due to the effect of in use heat in metal cutting and workpiece heat by conduction, makes sawtooth temperature exceed thermohardening and causes wearing and tearing and the wearing and tearing bonding with serrated surface of cut timber material to be main causes that saw blade lost efficacy.After the crown quenching that the processing of metal current cold hot cut circular saw blade adopts, lonneal cannot overcome the above problems, concrete operations are air coolings after sawtooth being heated to more than 750 degrees Celsius with electrode, then to adopt 250 to 350 degrees Celsius to be incubated sawtooth hardness after 4 low-temperature tempering be HRC56-63.
The cold and hot metal cutting circular saw blade of current international and domestic production adopts integral quenching and the modified rear tooth point local quenching process of entirety, the problem that coping saw blade material limitation causes service life low cannot be solved, and the metal circular saw shortcoming adopting Integral alloy and local welding alloy is that high cost complex process difficulty of processing is large, be more than 4 times of cold and hot metal cutting circular saw blade for the metal circular saw price of local welding alloy and cannot be used for earnestly, active line speed is only metal cold hot-cutting saw blade 1/40.
Utility model content
The purpose of this utility model is to provide a kind of long service life, processes simple metal circular saw.
For achieving the above object, the technical solution adopted in the utility model is: a kind of metal circular saw, comprises blade body, and blade body medium design has installing hole, and the periphery design of blade body has sawtooth, it is characterized in that: the two sides of described sawtooth are designed with coating.
In this structure, described sawtooth upper surface, lower surface and crest top land are designed with coating.
In this structure, described coating is multilayer.
In this structure, described coating is positioned at crenature working face 1/3 place, periphery of sawtooth, and the material of coating is different from blade body material.
In this structure, the thickness of described coating is 0.001mm-2mm.
In this structure, the thickness of described coating is 1mm.
In this structure, described coating is hard alloy coating, metal-cermic coating or multiple elements design alloy coat, and described multiple elements design alloy coat is the multiple elements design alloy with lubrication and antisticking activity of sulfur-bearing or molybdenum.
In this structure, described coating and blade body be combined into metallurgical binding, described metallurgical binding is the metallurgical binding with diffusion transition layer.
The utility model has the advantages of and be: due to the utility model product, friction area can be reduced and reach energy-saving effect, otch burr can be reduced improve the quality of products, hardness and wearability can be kept at more operation at high temperature, so use the utility model can extend the service life of this product, preparation for processing is simple, and result of use is good.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, 2, 3, a kind of metal circular saw, comprises blade body 1 to the utility model, and blade body 1 medium design has installing hole, and the periphery design of blade body 1 has sawtooth 2, it is characterized in that: the two sides of described sawtooth 2 are designed with coating 3.In the present embodiment, described sawtooth 2 upper surface, lower surface and crest top land are designed with coating 3.In the present embodiment, described coating 3 is multilayer.In the present embodiment, described coating 3 is positioned at crenature working face 1/3 place, periphery of sawtooth 2, and the material of coating 3 is different from blade body 1 material.In the present embodiment, the thickness of described coating 3 is 0.001mm-2mm.In the present embodiment, the thickness of described coating 3 is 1mm.In the present embodiment, described coating 3 is hard alloy coating, metal-cermic coating or multiple elements design alloy coat, and described multiple elements design alloy coat is the multiple elements design alloy with lubrication and antisticking activity of sulfur-bearing or molybdenum.In the present embodiment, described coating 3 is combined into metallurgical binding with blade body 1, and described metallurgical binding is the metallurgical binding with diffusion transition layer.
The thermohardening of coating is higher than 550 degrees Celsius, due to blade body with coating formation metallurgical binding intensity is high ensures that coating plays effect, and local adopts coating to make alloy be used in blade to give full play to the Wear-resistant, high-temperature resistant bite-resistant of expensive alloy material and reduce friction effect and can improve metal circular saw service life, reduce costs, the cated saw blade of this tool can solve the insurmountable performance deficiency of metal current cold hot cut circular saw blade.
The utility model provides one and utilizes electrode material for graphite and alloy, according to sawtooth and sawtooth both sides shape and size, spin coating is different to the cladding material desiccated surface of blade body material, cladding material is carbide alloy, cermet, various metals and alloy, sulfur-bearing Mo-contained alloy powdery paints, resistance sintering power supply be 50HZ primary voltage 380V secondary voltage be less than 24V principal current be less than the 100A heat time be less than within 35 seconds, make sawtooth form metallurgical binding on original surface there is the structure that thickness is greater than one or more layers new superficies of 0.001 millimeter.
Embodiment recited above is only be described preferred embodiment of the present utility model; not design of the present utility model and protection domain are limited; under the prerequisite not departing from the utility model design concept; the various modification that in this area, common engineers and technicians make the technical solution of the utility model and improvement, all should fall into protection domain of the present utility model.
