Description

A high-strength and low-noise diamond circular saw blade substrate

technical field

The utility model relates to a high-strength and low-noise diamond circular saw blade substrate, which belongs to the technical field of cutting tools.

Background technique

Diamond circular saw blades are widely used in the cutting of stone, ceramics, concrete, etc. As shown in Figure 4, the base of a traditional diamond circular saw blade has evenly distributed serrations on the outer circle, and there is a "U" or "R" penetrating water groove between each serration. Periodic cutting in and out of sawtooth is an intermittent machining process, which bears a large impact during the cutting process, the cutting process is unstable, the stress at the root of the tooth is concentrated, and fatigue cracks are prone to occur. In addition, the water tank cuts off the outer circumference of the saw blade, so that the n=ks/2 or n=ks (k=1,2,3...) pitch mode of the matrix is split, increasing the modal density of the matrix and increasing the radiation noise of the matrix .

Utility model content

The purpose of this utility model is to provide a high-strength and low-noise diamond circular saw blade matrix capable of stable cutting, which can reduce the impact during processing and realize stable cutting; at the same time reduce the modal density of the matrix and further reduce the radiated noise.

The purpose of this utility model is achieved in that:

A high-strength and low-noise diamond saw blade base body, comprising a saw blade base body, a center hole is provided at the center of the saw blade base body, and spaced holes are provided on the outer circles of the upper and lower radial surfaces of the saw blade base body. Non-penetrating sink for cloth.

The non-penetrating water tank is a semi-penetrating water tank, and its depth is half of the thickness of the saw blade base; to half the thickness of the substrate.

The serrations formed between every two adjacent semi-penetrating water grooves are provided with cutter heads, and all the cutter heads on the same radial plane form a circle; that is, on the upper radial face and the lower radial face of the entire base All have a ring of cutter heads.

The cutter head is welded on the sawtooth.

The semi-penetrating water tank is U-shaped, R-shaped or semicircular in shape.

The high-strength and low-noise diamond circular saw blade matrix provided by the utility model has the following beneficial effects:

1. Add auxiliary support to increase cutting stability. Change the evenly distributed water grooves on the outer periphery of the traditional diamond circular saw blade base to semi-penetrating water grooves evenly spaced on both sides. When the next sawtooth cuts in, the sawtooth on the side is cutting stably, which is equivalent to adding an auxiliary support to the side to increase the cutting process. Stability, to achieve continuous and stable cutting.

2. Since the water tank is a half-penetrating water tank, the cutting thickness of the cutter head is halved, reducing the cutting impact; the cutting head is only half of the original, the impact force is reduced, the cutting stability is increased, and the radiation noise is reduced.

3. Optimize the force of the sawtooth and improve the fatigue life. The original penetrating water tank has severe stress concentration at the tooth root, while the new diamond circular saw blade base has a non-penetrating water tank, and the entire water tank side wall is stressed, which disperses the force on the teeth and reduces the stress concentration at the tooth root. The excessive concentration of stress at the tooth root is eliminated, and the impact resistance of the saw blade base is improved.

4. Reduce the modal density of the diamond circular saw blade matrix and reduce radiation noise. Avoid the discontinuity of the outer periphery of the diamond circular saw blade matrix caused by the cutting of the water tank, suppress the matrix n=ks/2 or n=ks (k=1,2,3...) pitch modal splitting, and reduce the mode of the matrix Density, reducing the radiation noise of the substrate.

Detailed ways

As shown in Figure 1 and Figure 2, the utility model includes a saw blade base 2, a central hole 1 is provided on the saw blade base 2, a central hole 1 is provided at the center of the saw blade base 2, and the top and bottom of the saw blade base 2 The outer circles of the two radial faces are provided with semi-penetrating water grooves 4 evenly spaced, and the depth of the half-penetrating water grooves 4 is half of the thickness of the saw blade substrate 2; the interval distribution here refers to; There is a semi-penetrating water tank located on the lower radial plane between two semi-penetrating water tanks; a semi-penetrating water tank located on the upper radial plane is provided between every two semi-penetrating water tanks on the lower radial plane. Sink; the serrations formed between every two adjacent semi-penetrating water tanks 4 are provided with cutter heads 5, and all cutter heads 5 form a circle; that is, the upper radial surface and the lower radial surface of the entire substrate are provided with There is a circle of blades.

The depth of the semi-penetrating water groove is from the upper radial side of the saw blade base body down or the small radial side up to half of the thickness of the base body.

The utility model changes the design of the existing saw blade matrix penetrating water tank (as shown in Fig. 4 A) into a semi-penetrating water tank at intervals on both sides. 3.

The cutting process of the utility model is shown in Figure 1. The workpiece 7 to be processed enters the cutting area during the cutting process, and the cutter head 5 begins to cut stably. During the cutting process of the head 6, the cutter head 5 provides side auxiliary support for it during the cutting process, increasing the stability of the cutting. And because the cutter head is alternately welded on both sides of the outer circle, the thickness of the cutting head is halved, which further reduces the impact during the cutting process.

In this process, the water tank 4 plays the role of chip removal in the saw kerf.

Although the specific implementation of the utility model has been described above in conjunction with the accompanying drawings, it does not limit the protection scope of the utility model. Those skilled in the art should understand that on the basis of the technical solution of the utility model, those skilled in the art do not need to Various modifications or deformations that can be made with creative efforts are still within the protection scope of the present utility model.
