Description

Technical Field

[0001] The utility model relates to the technical field of saw blades, in particular to an efficient woodworking combined saw blade. Background Technique

[0002] With the development of the woodworking industry, people have put forward higher and higher requirements for the quality and efficiency of wood products. For traditional woodworking saw blades, the step-and-flat teeth are relatively rough, and the cutting edge may not be smooth enough, requiring subsequent trimming. This is because the tooth profile design of the step-and-flat teeth does not particularly consider the profiling effect, so obvious marks may be left on the cutting edge. Therefore, developing a new type of saw blade that can both cut and profile has become an urgent need in the current woodworking field.

[0003] Now, in order to solve the above technical problems, the utility model designs an efficient woodworking combined saw blade. Content of the Utility Model

[0004] The utility model provides an efficient woodworking combined saw blade, aiming to solve the problems that the existing saw blades do not consider the profiling effect and the cutting edge is not smooth. The technical solution is as follows:

[0005] An efficient woodworking combined saw blade, characterized in that: it includes a saw plate, a first saw tooth and a second saw tooth. The first saw tooth includes a connecting part, an arc part and a missing part. The arc part is arranged on one side of the connecting part and has an arc that bends outward. The missing part is located on the same side as the arc part and has an arc that depresses towards the connecting part. The second saw tooth is mirror-symmetrical to the first saw tooth, and a hollow part is arranged on the saw plate.

[0006] On the basis of the above technical solution, a number of saw teeth are evenly processed on the outer edge of the saw plate. The first saw teeth and the second saw teeth are alternately arranged at intervals on the saw plate to form a combined saw blade.

[0007] On the basis of the above technical solution, tooth pieces are made respectively with the first saw teeth and the second saw teeth. The tooth piece made with the first saw teeth and the tooth piece made with the second saw teeth are arranged staggeredly. Pin holes are opened on the tooth pieces, and after connecting the two tooth pieces with pins, they are then connected to the saw plate to form a combined saw blade.

[0008] Preferably, the saw plate is made of steel.

[0009] Preferably, both the first saw tooth and the second saw tooth are made of diamond.

[0010] Advantageous Effects

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: On the one hand, the design of the arc portion can increase the contact area with the material, thereby improving the cutting speed and efficiency. The arc portion can better guide the material into the cutting area, reducing friction and resistance. On the other hand, due to the special design of the saw blade tooth shape, it can produce a certain trimming effect on the cutting edge. The arc portion can produce a smooth cutting edge, while the missing portion helps to reduce the contact area between the saw blade and the material, reducing the cutting resistance, thereby reducing the deformation and tearing of the material. On the other hand, due to the existence of the missing portion, this design can promote air flow and help carry away the heat generated during the cutting process. Good heat dissipation performance can prevent the saw blade from overheating and extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] As Figure 4 shown, it is the tooth profile of a ladder flat tooth. The machining of the ladder flat tooth results in a rough cutting edge and burrs, and subsequent machining is required for correction.

[0022] Embodiment 1

[0023] As Figures 1 to 3 shown, a high-efficiency woodworking combined saw blade, characterized in that it includes a saw plate 1, a first saw tooth 2 and a second saw tooth 3. The first saw tooth 2 includes a connecting portion 21, an arc portion 22 and a missing portion 23. The arc portion 22 is arranged on one side of the connecting portion 21 and has an arc bent outward. The missing portion 23 is located on the same side as the arc portion 22 and has an arc recessed toward the connecting portion 21. The second saw tooth 3 is mirror-symmetrical to the first saw tooth 2. A hollow portion 4 is arranged on the saw plate 1. A plurality of saw teeth are evenly machined on the outer edge of the saw plate 1. The first saw teeth 2 and the second saw teeth 3 are alternately arranged on the saw plate at intervals to form a combined saw blade.

[0024] The design of the arc portion 22 enables more teeth to participate in the cutting process when the saw blade is cutting. Compared with a straight-edge tooth profile, the arc portion can cover a larger cutting area, which means that each tooth processes more material per unit time, thus accelerating the cutting speed. The arc portion 22 makes the cutting pressure more evenly distributed on the material being cut. This helps to reduce local stress concentration and avoid cracking or deformation of the material, which is particularly important when cutting brittle materials.

[0025] The missing portion 23 can reduce the contact area between the saw blade and the material, thereby reducing the cutting resistance and making it easier for the saw blade to penetrate the material. Since heat is generated during the sawing process, the missing portion can help air circulation and help cool the saw blade to prevent damage caused by overheating.

[0026] The missing part 23 also has a certain chip removal effect. During the cutting process of the saw blade, chips are generated. If these chips are not discharged in time, they may accumulate between the saw blade and the material being cut, causing additional resistance, reducing the cutting efficiency, and even possibly causing the saw blade to get stuck or damaged. The existence of the missing part provides a channel for the chips, allowing them to slide naturally during the cutting process instead of accumulating on the surface of the saw blade. This can maintain a clean working interface between the saw blade and the material, improve the cutting quality and efficiency, and at the same time reduce the possibility of saw blade wear.

[0027] The hollowed-out part 4 can reduce the weight of the saw blade, improve the convenience of operation, increase air circulation, help cool the saw plate, prevent overheating, reduce resonance during high-speed rotation of the saw plate, and reduce noise and vibration.

[0028] The saw plate 1 is made of steel. For example, 75CR1, 75CR1 stainless steel has excellent corrosion resistance, can protect the saw plate from moisture and chemical substances, extend the service life, has good strength and toughness, and can resist stress and impact during the sawing process.

[0029] Both the first saw teeth 2 and the second saw teeth 3 are made of diamond.

[0030] Embodiment 2

[0031] Separate tooth slices are made with the first saw teeth 2 and the second saw teeth 3 respectively. The tooth slice made with the first saw teeth 2 and the tooth slice made with the second saw teeth 3 are arranged staggeredly. Pin holes 5 are provided on the tooth slices. After connecting the two tooth slices with pins and then connecting them to the saw plate 1, a combined saw blade is formed. Through the pin holes 5, the staggered position of the tooth slices can be adjusted to facilitate the accurate positioning and calibration of the cutting line.

[0032] Each tooth slice is provided with 92 first saw teeth 2 and second saw teeth 3, with a rake angle of 6.5° ± 1° and a tooth depth * width of 4.5 * 1.5°

[0033] Adopting a modular design to make the first saw teeth 2 and the second saw teeth 3 into independent tooth slices is convenient for replacement and maintenance. Different numbers of the first saw teeth 2 and the second saw teeth 3 can also be freely combined according to needs to meet different cutting requirements. The separate tooth slice design makes maintenance and repair simpler, and only the damaged part needs to be replaced.

[0034] Since the saw blade rotates, the cutting actions are alternately performed on the left and right sides, which helps to offset part of the vibration, thereby reducing the overall vibration level.

[0035] The present invention has been described by way of example above, but the present invention is not limited to the above specific embodiments. Any modification or variation based on the present invention falls within the scope of protection required by the present invention.
