Abstract
The utility model provides an improved composite tool for cutting and abrading which is particularly suitable for the cutting and grinding for stone, glass, high-hardness steel, etc. The utility model is composed of a main body made by steel plate and a plating emery, wherein, the main body is composed of a central part with a connecting hole, an edge part with a sawtooth, and a truncated cone part used for connecting the central part and the edge part. The improved point is that the width and the depth of the sawtooth is widened, the emery adopts the method of the combination of point sputtering and successive sputtering, and the service life of tools and work efficiency is further enhanced.
Description
The utility model relates to a kind of instrument that is installed on the toolroom machine, on particularly a kind of toolroom machine that is installed in processing stone material, glass, hardwood and high rigidity fragility steel etc., can cut the composite tool with grinding operation simultaneously.
When the high rigidity fragile material of processing stone material and so on, cutting action and grinding step separated in the past, used two kinds of different instruments.Cutting tool generally is the plate shaped saw blade that studs with the high rigidity blade, and milling tool is the grinding wheel that diamond dust and abrasive material are formed with adhesive bond.It is low to use the instrument of this separate machined to exist efficient, long processing time, and instrument consumption is big, and otch is wide, the shortcoming of low quality or the like of machined surface.
A kind of " cutting and abradant composite tool " of inventor's design disclosed among the China utility model patent ZL 96201123.1.This composite tool has the plate shaped peripheral part by core, band saw tooth, with the main part of the composition that is connected this two-part frusto-conically shaped portion, and is bonded in diamond dust on the peripheral part with method of spray plating.The rigidity of this composite tool is big, and otch is narrow, can cut simultaneously and grind, and process time is short.And, owing to offered air vent, reduced the instrument rising degree of temperature in use in the peripheral part of main body, can improve life tools and working (machining) efficiency greatly.
But through after the practice of several years, the inventor finds that also there is some weak point in above-mentioned composite tool.
At first,, influenced the service life of composite tool, increased the cutting resistance in the process because the design of the shape and size of sawtooth is reasonable inadequately on the peripheral part of main body.Specifically, the sawtooth on this composite tool is the triangle of drift angle between 50 °～70 °, and addendum width is between 0.3～1mm, and therefore, the quantity of sawtooth is very many on whole circumference.Yet, use thisly to have bondd the composite tool of diamond dust when cutting in the peripheral part spraying plating, mainly be to utilize diamond dust that the grinding function of stiff materials is ground off processed material, rather than rely on sawtooth to cut machined material.So, this instrument in the past, sawtooth quantity is a lot, but addendum width has only 0.3～1mm, the area of on circumference, participating in cutting work seldom, so resistance is big, cutting speed is slower.And each tooth of participating in cutting work is easy to wearing and tearing, is difficult to the life-span of further raising instrument.In addition, the tooth top that is acute angle reduces the intensity of sawtooth, is easy to damage.
Secondly, composite tool in the past the peripheral part as the plane of grinding on spraying plating diamond dust all, so just be unfavorable in the attrition process process, discharging abrasive dust and disperse because of cutting and the heat that rubs and produced.
The purpose of this utility model is exactly at existing the problems referred to above in the ZL96201123.1 utility model patent, to the quantity of sawtooth, shape and angle, and improve at the position of spraying plating diamond dust, provide a kind of cutting resistance little, cutting that life tools are longer and abradant composite tool.
Because composite tool of the present utility model is improved on the basis of ZL96201123.1 patent, therefore, above-mentioned patent is the immediate list of references of the utility model, can be used for illustrating the utility model.
For achieving the above object, cutting of the present utility model and abradant composite tool comprise the main body that steel plate is made and are used as the diamond dust of abrasive material.Aforementioned body has the plate shaped peripheral part of sawtooth by the plate shaped core that has the connecting hole that connects with toolroom machine on the circumference, form with the frusto-conically shaped portion that is connected core and peripheral part; Above-mentioned diamond dust spraying plating is bonded on the peripheral part of aforementioned body, it is characterized in that, above-mentioned sawtooth is trapezoidal, and the drift angle of sawtooth all falls into fillet.
The diamond dust of above-mentioned spraying plating on the main body peripheral part covers entire area on the parts of tooth of sawtooth and excircle, below parts of tooth, then only cover a part of area on as the bottom surface of grinding, and is beneficial to chip removal and distribute heat.
In order to distribute the heat that produces because of friction in the process, also on the peripheral part of aforementioned body, offered the plurality of rows air vent of partition distance from inside to outside.Like this, in the high speed rotary course when tool processes, ambient air just can flow through these air vents, strengthens the cooling of instrument, reduces the temperature of instrument.
Above-mentioned plurality of rows air vent preferably is evenly distributed on the annulus area of peripheral part, the diameter of air vent is in 2～8mm scope, and, the line at center of each row's air vent, and be 30 °～60 ° by the angle between the middle air vent radius centered of this row's air vent.
The cone angle of the frusto-conically shaped portion of aforementioned body is in 60 °～150 ° scope.
The front top rake of above-mentioned trapezoidal sawtooth is 90 °, back drift angle between 110 °～150 °, preferably 125 °; The addendum width of sawtooth between 6～22,14mm preferably; Tooth depth between 2.5～12mm, 6mm preferably.
The thickness of the steel plate that aforementioned body is used should be selected according to the maximum outside diameter of main body, and diameter is long more, and steel plate is thick more, generally in 0.5～1.0mm scope.The material of steel plate can adopt high strength medium carbon structure steel or structural alloy steel.
