Anti-rubbing type circular-arc tooth saw blade

Abstract

This utility model relates to the field of arc-tooth saw blade technology, and discloses an anti-impact arc-tooth saw blade, including a main saw blade. A first saw tooth and a second saw tooth are fixedly connected to the outer wall of the main saw blade. An alloy cutting tip is fixedly connected to the outer wall of one side of each of the first and second saw teeth. A first heat dissipation groove is formed on the outer wall of both the front and rear ends of the main saw blade, and a second heat dissipation groove is formed around the four sides of the upper surface of the main saw blade. In this utility model, the first and second saw teeth of the arc-tooth saw blade adopt a deflected cutting edge structure, and the deflection directions of the first and second saw teeth are different. This allows the chip discharge path and the cutting force direction to alternately deflect between different teeth, avoiding continuous impact in the same direction accumulating at the same local tooth root. Furthermore, the arc-tooth saw blade is provided with a first heat dissipation groove, which, together with the second heat dissipation groove, can distribute the heat generated during cutting to the entire saw blade, thereby dissipating heat more efficiently.

Description

Technical Field

[0001] This utility model relates to the field of arc-tooth saw blade technology, and in particular to an anti-jamming arc-tooth saw blade. Background Technology

[0002] Arc-tooth saw blades are tools used for woodworking and metal cutting. Their teeth are arranged in an arc shape, which has excellent cutting stability and durability. During the cutting process, the arc teeth can distribute the cutting force more evenly, reduce vibration, improve guidance and cutting smoothness, and at the same time have good tolerance for material adhesion and thermal deformation. They are suitable for quickly and stably completing longitudinal cutting and cylindrical surface processing.

[0003] However, traditional circular arc toothed saw blades, with their offset blades in the same direction, lack directional switching between adjacent teeth in terms of cutting force and chip removal path. This can easily lead to continuous impact accumulation in the same tooth root area, resulting in stress concentration, fatigue damage, or local failure.

[0004] Therefore, those skilled in the art have provided an anti-jamming circular arc toothed saw blade to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-tooth-striking circular arc-shaped saw blade. The first and second teeth of this circular arc-shaped saw blade have a deflection edge structure, and the deflection edges of the first and second teeth are in different directions. This allows the chip discharge path and the cutting force direction to deflect alternately between different teeth, avoiding the accumulation of continuous impact in the same direction at the same local tooth root, thereby reducing the probability of tooth knocking.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An anti-damage circular arc-shaped saw blade includes a main saw blade. The outer wall of the main saw blade is fixedly connected with a first saw tooth and a second saw tooth. An alloy cutter head is fixedly connected to the outer wall on one side of the first saw tooth and the second saw tooth. The outer wall at the front end and the rear end of the main saw blade are provided with a first heat dissipation groove. The upper surface of the main saw blade is provided with a second heat dissipation groove around the perimeter.

[0008] Through the above technical solution, the arc-shaped toothed saw blade is provided with a first heat dissipation groove, which, together with the second heat dissipation groove, can distribute the heat generated by cutting to the entire saw blade, thereby dissipating the heat more efficiently and preventing the heat from being concentrated in a single area at the root or tip of the tooth.

[0009] Furthermore, the main saw blade, the first saw tooth, and the second saw tooth are all made of high-carbon alloy steel;

[0010] Through the above technical solutions, high-carbon alloy steel material can improve the heat conduction effect of the main saw blade, the first saw tooth, and the second saw tooth while possessing good strength and toughness.

[0011] Furthermore, the alloy cutting tip is made of high-speed steel;

[0012] Through the above technical solutions, alloy cutter heads made of high-speed steel can improve wear resistance and thermal stability.

[0013] Furthermore, a mounting block is fixedly connected to the center of the upper surface of the main saw blade;

[0014] The above technical solution allows the saw blade to be installed and fixed on the required equipment for cutting operations by setting up an installation block.

[0015] Furthermore, a main mounting groove is provided at the center of the upper surface of the mounting block;

[0016] The above technical solution enables the mounting block to be positioned and connected to the drive spindle by setting a main mounting slot.

[0017] Furthermore, auxiliary mounting holes are provided around the four sides of the upper surface of the mounting block;

[0018] The above technical solution facilitates the positioning and restriction of the mounting block after installation by setting auxiliary mounting holes.

[0019] This utility model has the following beneficial effects:

[0020] 1. The present invention proposes an anti-tooth-striking circular arc-shaped saw blade. Compared with most traditional circular arc-shaped saw blades, the first and second teeth of the circular arc-shaped saw blade adopt a blade edge deflection structure, and the deflection directions of the first and second teeth are different. This allows the chip discharge path and the cutting force direction to deflect alternately between different teeth, avoiding the continuous impact in the same direction from accumulating in the same local tooth root, thereby reducing the probability of tooth knocking.

[0021] 2. The present invention proposes an anti-damage circular arc tooth saw blade, which is provided with a first heat dissipation groove and a second heat dissipation groove to distribute the heat generated by cutting to the entire saw blade, thereby dissipating the heat more efficiently and preventing the heat from being concentrated in a single area at the root or tip of the tooth.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] One embodiment of this utility model is provided:

[0028] Reference Figure 1 , 2 3. A type of anti-damage circular arc tooth saw blade, comprising a main saw blade 1, with a first saw tooth 2 and a second saw tooth 3 fixedly connected to the outer wall of the main saw blade 1 respectively, and an alloy cutter head 9 fixedly connected to the outer wall on one side of the first saw tooth 2 and the second saw tooth 3 respectively. A first heat dissipation groove 4 is provided on the outer wall of the front end and the rear end of the main saw blade 1, and a second heat dissipation groove 5 is provided around the upper surface of the main saw blade 1. The circular arc tooth saw blade is provided with the first heat dissipation groove 4, which, together with the second heat dissipation groove 5, can distribute the heat generated by cutting to the entire saw blade, thereby dissipating the heat more efficiently and preventing the heat from being concentrated in a single area at the root or tip of the tooth.

[0029] Reference Figure 1 , 2 1. The main saw blade 1, the first saw tooth 2, and the second saw tooth 3 are all made of high carbon alloy steel. High carbon alloy steel has good strength and toughness, and can improve the heat conduction of the main saw blade 1, the first saw tooth 2, and the second saw tooth 3. The alloy cutter head 9 is made of high speed steel. The alloy cutter head 9 made of high speed steel can improve wear resistance and thermal stability.

[0030] Reference Figure 1 , 23. A mounting block 6 is fixedly connected to the center of the upper surface of the main saw blade 1. By setting the mounting block 6, the saw blade can be installed and fixed on the required equipment for cutting operations. A main mounting groove 7 is provided at the center of the upper surface of the mounting block 6. By setting the main mounting groove 7, the mounting block 6 can be positioned and connected with the drive spindle. Auxiliary mounting holes 8 are provided around the upper surface of the mounting block 6. By setting the auxiliary mounting holes 8, it is convenient to position and limit the mounting block 6 after installation.

[0031] Working principle: First, the saw blade is installed on the required equipment via the mounting block 6 (connecting the main mounting groove 7 to the drive spindle of the equipment and connecting the auxiliary mounting hole 8 to the positioning and limiting screws). The drive of the equipment can control the main saw blade 1 to rotate, thereby controlling the first saw tooth 2 and the second saw tooth 3 to rotate, so that the alloy cutter head 9 can cut the required material. The first saw tooth 2 and the second saw tooth 3 both adopt the blade edge deflection structure, and the first saw tooth 2 and the second saw tooth 3 adopt the arc tooth shape and deflection structure, and make the deflection direction of adjacent teeth opposite (that is, one tooth deflects to the left, the next tooth deflects to the right, and so on). This can significantly improve the directional effect of anti-tooth hitting and reduce the probability of tooth hitting.
