Description

Technical Field

[0001] This utility model relates to the field of saw blade technology, and in particular to a saw blade substrate with high and low teeth and deep and shallow water channels with a wear-resistant coating on the teeth. Background Technology

[0002] Existing saw blades have several teeth on the outer side of the blade body, which interlock to form a water groove. Typically, both the teeth and the water grooves are of uniform size. This type of saw blade presents the following problems when cutting stone:

[0003] (1) The uniform size of the saw teeth results in a relatively slow cutting speed and poor heat dissipation, which increases the risk of saw blade wear or burning due to overheating;

[0004] (2) The uniform size of the water tank has poor chip removal and heat dissipation capabilities. During the cutting process, the accumulation of chips can easily lead to blockage or frictional heat generation, increasing the risk of saw blade wear or burning due to overheating. Utility Model Content

[0005] This utility model provides a saw blade substrate with high and low teeth and deep and shallow water grooves with a wear-resistant coating on the teeth, aiming to solve the problems of slow cutting, poor heat dissipation and poor chip removal ability caused by the uniform size of the saw teeth and water grooves in the existing saw blades.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A saw blade substrate with a wear-resistant coating on the teeth, comprising a saw blade substrate, wherein a plurality of saw teeth are uniformly provided on the outer side of the saw blade substrate, and the saw teeth cooperate to form a water groove, wherein the saw teeth are high teeth and low teeth, and the water groove is a deep groove and a shallow groove.

[0008] Preferably, the distance from the outer wall of the tooth tip of the high-toothed component to the center of the saw blade substrate is greater than the distance from the outer wall of the tooth tip of the low-toothed component to the center of the saw blade substrate.

[0009] More preferably, the high teeth and low teeth are arranged alternately around the axis, with the high teeth being symmetrical about the intermediate axis in pairs, and the low teeth being symmetrical about the intermediate axis in pairs.

[0010] Furthermore, the high teeth and low teeth are arranged alternately around the axis in the same regular group, and the number of high teeth and low teeth in the regular group is at least one.

[0011] Preferably, the distance from the bottom of the deep groove to the center of the saw blade base is greater than the distance from the bottom of the shallow groove to the center of the saw blade base.

[0012] More preferably, the deep grooves and shallow grooves are arranged alternately around the axis, with the deep grooves being symmetrical about the intermediate axis in pairs, and the shallow grooves being symmetrical about the intermediate axis in pairs.

[0013] Furthermore, the deep grooves and shallow grooves are arranged alternately around the axis in the same regular pattern, and the number of deep grooves and shallow grooves in each regular pattern is at least one.

[0014] Preferably, a wear-resistant coating is provided on the outer wall of the high teeth, low teeth, deep grooves and shallow grooves.

[0015] More preferably, the thickness of the wear-resistant coating is 10~30μm.

[0016] The beneficial effects of this utility model are:

[0017] 1. The alternating high and low tooth design increases the chip removal space between the cutter heads, reduces the accumulation of mud and sand during sawing, and reduces the risk of saw blade wear or burning due to overheating. When cutting stone, the high tooth part can quickly cut the material, while the low tooth part accelerates chip removal through a larger water channel to avoid clogging.

[0018] 2. Improve chip removal capability: Deep grooves can hold more chips, preventing chip accumulation during cutting and avoiding blockage or frictional heat generation. Shallow grooves can enhance the rigidity of the saw blade and guide chips to be concentrated and discharged into the deep grooves, reducing chip adhesion to the saw teeth or grooves.

[0019] 3. Improve the balance between heat dissipation and strength. Deep grooves can increase the heat dissipation area and quickly remove heat through air flow or coolant to reduce the temperature of the saw blade. Shallow grooves can maintain the structural strength of the saw blade base and prevent the saw blade from being easily deformed or broken due to excessive groove depth.

[0020] 4. Reduce vibration and noise: Alternating groove depths can disrupt the resonant frequency during cutting, reducing vibration and noise and improving cutting stability. Attached Figure Description

[0024] The embodiments will be further described below with reference to the accompanying drawings.

[0025] like Figures 1-2 As shown in the preferred embodiment 1, a saw blade substrate with high and low teeth and deep and shallow water grooves with a wear-resistant coating on the teeth includes a saw blade substrate 1. A plurality of saw teeth are uniformly provided on the outer side of the saw blade substrate 1. The saw teeth cooperate to form water grooves. The saw teeth are high teeth 2 and low teeth 3. The water grooves are deep grooves 4 and shallow grooves 5.

[0026] The distance from the outer wall of the high tooth 2 to the center of the saw blade base 1 is greater than the distance from the outer wall of the low tooth 3 to the center of the saw blade base 1.

[0027] The high teeth 2 and low teeth 3 are arranged alternately around the axis, with the high teeth 2 being symmetrical about the intermediate axis in pairs, and the low teeth 3 being symmetrical about the intermediate axis in pairs. They can be arranged regularly or irregularly, depending on the actual situation, but symmetry must be ensured to guarantee the force balance during cutting, similar to the balancing of a centrifuge.

[0028] The distance from the bottom of the deep groove 4 to the center of the saw blade base 1 is greater than the distance from the bottom of the shallow groove 5 to the center of the saw blade base 1.

[0029] The deep grooves 4 and shallow grooves 5 are arranged alternately around the axis. The deep grooves 4 are symmetrical about the intermediate axis in pairs, and the shallow grooves 5 are symmetrical about the intermediate axis in pairs. They can be arranged regularly or irregularly, depending on the actual situation, but symmetry must be ensured to guarantee the force balance during cutting, similar to the balancing of a centrifuge.

[0030] As a preferred embodiment 2, when arranged in a regular pattern:

[0031] The high teeth 2 and low teeth 3 are arranged alternately around the axis in the same regular group, and the number of high teeth 2 and low teeth 3 in the regular group is at least one.

[0032] The deep grooves 4 and shallow grooves 5 are arranged alternately around the axis in the same regular pattern, and the number of deep grooves 4 and shallow grooves 5 in each regular pattern is at least one.

[0033] like Figure 1 and Figure 2 As shown, based on Embodiment 2, as a more preferred Embodiment 3, the high teeth 2 and low teeth 3 are arranged alternately around the axis in the same pattern group. The pattern group is 10 high teeth 2 first, then 1 low tooth 3, and this pattern group is cyclically arranged around the axis to achieve the alternating arrangement.

[0034] The deep grooves 4 and shallow grooves 5 are arranged alternately around the axis in the same pattern. Within each pattern group, there is one deep groove 4 followed by one shallow groove 5, and this pattern group is repeated around the axis to achieve the alternating arrangement.

[0035] In a preferred embodiment 4, a wear-resistant coating 6 is provided on the outer walls of the high teeth 2, low teeth 3, deep grooves 4, and shallow grooves 5. This improves the wear resistance and corrosion resistance of the serrations and the entire water groove in the outer ring tooth section.

[0036] The thickness of the wear-resistant coating 6 is 10~30μm.

[0037] Preferably, the boundary of the wear-resistant coating 6 is located at a point where it tapers 10mm towards the bottom of the deep groove 4. This does not affect the normal use of the saw blade substrate 1.

[0038] Preferably, the wear-resistant coating 6 can be a DLC coating.

[0039] The working principle of this utility model:

[0040] This utility model provides a saw blade substrate with high and low teeth and deep and shallow water grooves with wear-resistant coating on the teeth. The alternating high and low tooth design increases the chip removal space between the cutter heads, reduces the accumulation of mud and sand during sawing, and reduces the risk of saw blade wear or burning due to overheating. When cutting stone, the high tooth 2 part can quickly cut the material, while the low tooth 3 part accelerates chip removal through a larger water groove to avoid clogging.

[0041] To improve chip removal capability, the deep groove 4 can hold more chips, preventing chip accumulation during cutting and avoiding blockage or frictional heat generation. The shallow groove 5 can enhance the rigidity of the saw blade and guide the chips to be concentrated and discharged into the deep groove 4, reducing chip adhesion to the saw teeth or grooves.

[0042] To improve the balance between heat dissipation and strength, the deep groove 4 can increase the heat dissipation area and quickly remove heat through air flow or coolant to reduce the temperature of the saw blade. The shallow groove 5 can maintain the structural strength of the saw blade base and prevent the saw blade from being easily deformed or broken due to excessive groove depth.

[0043] To reduce vibration and noise, alternating grooves of varying depths can disrupt the resonant frequency during cutting, thereby reducing vibration and noise and improving cutting stability.
