Description
Technical field
The utility model relates to the instrument of the various metal material of a kind of sawing, specifically a kind of protecting against shock sintered carbide circular saw.
Background technology
Saw blade is widely used in the blanking procedure of mechanical processing industry because its manufacture is simple, easy to use, cutting efficient.Because the percentage elongation of steel alloy is high, the iron filings not frangibility of generation, or because of material uneven, traditional round saw blade cut steel alloy time there will be the shortcomings such as iron filings stick sawtooth, sawtooth tipping, saw life is low, sawing end face is of poor quality, production efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, when a kind of rational in infrastructure, handling ease, sawing be provided sawtooth not tipping, the protecting against shock sintered carbide circular saw of the quick sawing steel alloy of common saw blade can be substituted.
The technical scheme in the invention for solving the above technical problem is: a kind of protecting against shock sintered carbide circular saw, its saw bit matrix is provided with center mounting hole and drive hole, saw bit matrix outer ring studs with several sawtooth, described sawtooth by brazing on saw bit matrix, it is characterized in that: on described saw bit matrix each sawtooth be below correspondingly provided with a protecting against shock groove, be provided with an angle (λ) between described protecting against shock groove and corresponding sawtooth.
The numerical value of the angle (λ) between described protecting against shock groove and corresponding sawtooth is between 0 ° to 20 °.
Described protecting against shock trench bottom is provided with a circular hole.
1 to 1.2 times that described protecting against shock groove depth (H) is sawtooth height.
Sawtooth described in the utility model saw bit matrix is below provided with protecting against shock groove, and protecting against shock groove can solve sawtooth tipping problem.For different cutting objects, the machining angle λ of protecting against shock groove and the numerical value of depth H can be changed.Against existing technologies, the utility model is rational in infrastructure, production is simple, saw life is high, sawing time enhance the impact resistance of sawtooth, improve sawtooth chip breaking ability and prevent sawtooth tipping problem, can substitute the high efficiency sawing requirement that traditional round saw blade meets automatic production line alloy steel, be a kind of desirable protecting against shock sintered carbide circular saw.
Accompanying drawing explanation
Here is that the utility model is described in further detail by reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram of local I in Fig. 1.
Label in figure is: 1. sawtooth, 2. saw bit matrix, 3. drive hole, 4. center mounting hole, 5. protecting against shock groove.
Detailed description of the invention
As can be seen from Fig. 1, Fig. 2, the sintered carbide circular saw of a kind of protecting against shock of the utility model, its saw bit matrix 2 is provided with center mounting hole 4 and drive hole 3, if saw bit matrix 2 outer ring studs with individual sawtooth 1, described sawtooth 1 by brazing on saw bit matrix 2.Above-mentionedly belong to prior art, repeat no more.
As shown in Figure 2, feature of the present utility model is: on described saw bit matrix 2 each sawtooth 1 be below correspondingly provided with a protecting against shock groove 5, be provided with an angle (λ) between described protecting against shock groove 5 and corresponding sawtooth.
The numerical value of the angle (λ) between described protecting against shock groove 5 and corresponding sawtooth is between 0 ° to 20 °.
A circular hole 51 is provided with bottom described protecting against shock groove 5.
1 to 1.2 times that the working depth (H) of described protecting against shock groove 5 is sawtooth height.
Described protecting against shock groove 5 is close to sawtooth 1 and arranges below.
Sawtooth described in the utility model saw bit matrix is below provided with protecting against shock groove.Protecting against shock groove can solve sawtooth tipping problem.During sawing, protecting against shock groove 5 can cushion the suddenly big or suddenly small cutting resistance that sawtooth 1 runs into, and when running into the large resistance of high strength steel, protecting against shock groove 5 absorbs the resistance distortion of sawtooth 1, and when large resistance disappears, sawtooth 1 recovers stressless deformation state.For different cutting objects, the angle λ of protecting against shock groove and depth H and position can be changed.
The utility model is rational in infrastructure, production is simple, saw life is high, sawing time enhance the impact resistance of sawtooth, improve sawtooth chip breaking ability and prevent sawtooth tipping problem, can substitute the high efficiency sawing requirement that traditional round saw blade meets automatic production line alloy steel, be a kind of desirable protecting against shock sintered carbide circular saw.
