Abstract
Description
Technical Field
[0001] This utility model belongs to the field of saw blade cutting technology, and in particular relates to a MA combined type multifunctional saw tooth alloy saw blade with self-guiding anti-cutting deviation. Background Technology
[0002] Alloy circular saw blades are used in the cutting of non-metallic and metallic materials such as wood, plastic, and aluminum alloy. Existing circular saw blades consist of a saw blade body and carbide saw teeth welded to the periphery. The cutting of various materials is achieved by the alloy saw teeth welded to the saw blade and the saw blade body rotating. Different shapes and angles of the alloy saw teeth determine the cutting performance and processing accuracy of the saw blade.
[0003] Existing circular saw blades or saw teeth designs include alternating left and right beveled teeth, high and low trapezoidal flat teeth, and various combinations of different tooth shapes. Currently, the different tooth shapes are limited by the machining process of the tooth back angle surface, making it impossible to achieve a double-pointed, double-back-angled surface per tooth. This results in each tooth having two alternating left and right points. In actual cutting, to achieve a fine surface finish, the number of alloy saw teeth must be increased; otherwise, the cut surface will be uneven with obvious cutting marks, numerous and large burrs, poor cutting effect, and the assembly accuracy of the cut product will not meet design requirements. This necessitates additional machining such as milling to ensure surface accuracy, increasing processing costs and time. Therefore, we provide a self-guiding, anti-cutting MA combined multi-functional alloy saw blade to solve the above technical problems. Utility Model Content
[0004] The purpose of this invention is to provide a self-guiding, anti-offset MA combined multi-functional saw blade with alloy teeth. Through the specific structural design of the first alloy saw tooth and the second alloy saw tooth, the problems in the background art mentioned above are solved.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a self-guiding anti-cutting MA combined type multifunctional saw blade, including a saw blade base, on which a plurality of combined alloy saw teeth are provided. Each alloy saw tooth includes a first alloy saw tooth and a second alloy saw tooth, and the first alloy saw tooth and the second alloy saw tooth in any two adjacent combined alloy saw teeth are adjacent to each other; the side cutting surface of the first alloy saw tooth is provided with a first left cutting edge and a first right cutting edge, and the second alloy saw tooth is provided with a second left cutting edge and a second right cutting edge on opposite sides.
[0006] The present invention is further configured such that the first alloy saw tooth has a first left rear corner cutting edge, a first left side cutting tip, a first right cutting edge and a first right side cutting tip respectively on its two rear corner surfaces, and a centering cutting tip is formed at the highest point of the center of the first alloy saw tooth; the second alloy saw tooth has a second left rear corner cutting edge, a second right rear corner cutting edge, a second left side cutting tip and a second right side cutting tip respectively on its two rear corner surfaces.
[0007] The present invention is further configured such that the included angle D of the centering cutting tip is 130°-160°, the second left cutting tip and the second right cutting tip are symmetrical, and the included angle E of the second left cutting tip and the second right cutting tip is 130°-160°.
[0008] The present invention is further configured such that the second left cutting tip of the second alloy saw tooth is formed by the included angle of the second left cutting edge and the second rear left cutting edge, and the second right cutting tip is formed by the right cutting edge, the second right cutting edge and the second rear right cutting edge.
[0009] The present invention has the following beneficial effects: 1. By setting 5 cutting tips and 8 cutting blades in each combination of saw teeth during the cutting process, the present invention makes the saw blade with more cutting tips than the existing general saw tooth design, so as to reduce the wear rate of the saw tooth alloy during the cutting process, improve the service life of the saw blade, and improve the cutting accuracy and cutting speed.
[0010] 2. This utility model, by setting each tooth alloy symmetrical tooth tip design, can effectively prevent the saw blade from deviating to the left or right during cutting, and has a centering and anti-cutting function. It effectively reduces the cutting force of the saw blade and reduces the saw blade deviating caused by the temperature rise of the saw teeth during the cutting process, and reduces the rigidity of the base material, especially when cutting non-metals such as aluminum alloys. It effectively reduces the cutting quality decline caused by the sticking problem due to the temperature rise during the cutting of aluminum alloys, improves the cutting accuracy and saw blade service life, and at the same time reduces the power consumption of the motor.

Detailed Implementation
[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1
[0020] Please see Figure 1-4 This utility model is a self-guiding anti-cutting MA combined type multifunctional saw blade, including a saw blade base 1, on which a plurality of combined alloy saw teeth are provided. Each alloy saw tooth includes a first alloy saw tooth 2 and a second alloy saw tooth 3, and the first alloy saw tooth 2 and the second alloy saw tooth 3 in any two adjacent combined alloy saw teeth are adjacent to each other. The side cutting surface of the first alloy saw tooth 2 is provided with a first left cutting edge 201 and a first right cutting edge 202, and the second alloy saw tooth 3 is provided with a second left cutting edge 301 and a second right cutting edge 302 on opposite sides.
[0021] The operation process of this embodiment is as follows: During the cutting process, each alloy saw tooth rotates synchronously with the saw blade base 1. When the first alloy saw tooth 2 and the second alloy saw tooth 3 come into contact with the object to be cut, the first left cutting edge 201 and the first right cutting edge 202 of the first alloy saw tooth 2 and the second left cutting edge 301 and the second right cutting edge 302 of the second alloy saw tooth 3 come into contact with the object to be cut in sequence, so as to reduce the wear rate of the saw tooth alloy during the cutting process and improve the service life of the saw blade. Specific Implementation Example 2
[0023] Please see Figure 1-4 Based on the first specific embodiment, specifically, the first alloy saw tooth 2 has a first rear left cutting edge 203, a first left cutting tip 204, a first right cutting edge 205 and a first right cutting tip 206 respectively on its double rear corner surfaces, and a centering cutting tip 207 is formed at the highest point of the center of the first alloy saw tooth 2.
[0024] Furthermore, the second alloy saw tooth 3 has a second rear corner cutting edge 303, a second rear corner right cutting edge 304, a second left cutting tip 305, and a second right cutting tip 306 respectively on its double rear corner surfaces.
[0025] Furthermore, the included angle D of the center cutting tip 207 is 130°-160°; the second left cutting tip 305 and the second right cutting tip 306 are symmetrical, and the included angle E of the second left cutting tip 305 and the second right cutting tip 306 is 130°-160°.
[0026] Furthermore, the second left cutting tip 305 of the second alloy saw tooth 3 is formed by the angle between the second left cutting edge 301 and the second rear left cutting edge 303, and the second right cutting tip 306 is formed by the right cutting edge 302 and the second rear right cutting edge 304.
[0027] The operation process of this embodiment is as follows: During the cutting process, each alloy saw tooth rotates synchronously with the saw blade base 1. When the first alloy saw tooth 2 and the second alloy saw tooth 3 come into contact with the object to be cut, the first rear left cutting edge 203, the first left cutting tip 204, the first right cutting edge 205, the first right cutting tip 206, and the middle cutting tip 207 of the first alloy saw tooth 2 move synchronously with the saw blade base 1. The second rear left cutting edge 303, the second rear right cutting edge 304, the second left cutting tip 305, and the second right cutting tip 306 of the second alloy saw tooth 3 move synchronously with the saw blade base 1. This combination saw tooth design results in a saw blade with more tooth tips than the existing general saw tooth design, thereby reducing the wear rate of the saw tooth alloy during the cutting process. This design improves saw blade lifespan, cutting accuracy, and cutting speed. The symmetrical tooth design of each alloy tooth, due to the 130°-160° included angle D of the centering cutting tip 207 and the 130°-160° included angle E of the second left cutting tip 305 and the second right cutting tip 306, effectively prevents the saw blade from skewing during cutting. It features centering and anti-skewing functionality, effectively reducing the cutting force of the saw blade and minimizing temperature rise during cutting, which can lead to saw blade skewing and reduced substrate rigidity, especially when cutting non-metals such as aluminum alloys. It also effectively reduces the cutting quality degradation caused by blade sticking due to temperature rise during aluminum alloy cutting, improving cutting accuracy and saw blade lifespan while reducing motor power consumption.
