Description

Technical Field

[0001] This application relates to the field of sawing processing, and particularly relates to an efficient sawing band saw blade and a sawing processing device. Background Art

[0002] In sawing processing, especially for sawing large-sized and tough workpieces, sawing efficiency and saw blade life are key issues. In the traditional sawing process, the cutting area in the middle of the saw kerf is usually in a quasi-dry cutting condition, and it is difficult for the cutting fluid to effectively act on this area. When the workpiece size is large (width exceeds 0.5 meters), after the saw blade is embedded in the workpiece, due to the suction force of the workpiece, the saw blade is closely attached to both sides of the workpiece, resulting in the cutting fluid being unable to reach the cutting area in time. The heat in the chips cannot be discharged in time and is transferred to the saw teeth through heat conduction, causing the local temperature of the saw teeth to rise, thus triggering early chipping and aggravating adhesive wear, significantly reducing the service life of the saw blade. Summary of the Invention

[0003] The purpose of this application is to provide an efficient sawing band saw blade. Through a special tooth profile structure design, the cutting fluid can effectively enter the saw kerf and infiltrate the rake face of the saw teeth, thereby reducing the cutting temperature, delaying adhesive wear, and significantly improving the service life and sawing efficiency of the saw blade.

[0004] To achieve the above purpose, this application provides the following technical solutions: An efficient sawing band saw blade, the band saw blade has a saw tooth band; the saw tooth band is strip-shaped, and a plurality of saw teeth are arranged in sequence along the length direction of the band saw blade, and a tooth groove is formed between adjacent saw teeth, and an arc liquid storage groove is arranged on the tooth groove profile.

[0005] Further, the tooth groove profile includes a plurality of continuous arc segments, which are arc segments with radii of R1, R2, R3, and R5 respectively. The R2 arc segment is an arc profile with a protrusion on the rake face tooth groove profile; among them, R1≥2R2, R3<R5; At least two arc liquid storage grooves are arranged at intervals in the R3 radius arc segment, and the radius of the arc segment formed by the combined connection of the axis centers of the multiple arc liquid storage grooves is R4, and R3 = R4 is satisfied.

[0006] Further, the diameter of the arc liquid storage groove is d, and the center distance between adjacent arc liquid storage grooves is L.

[0007] Further, the embedding profile arc angle of the arc liquid storage groove is 360° - θ, where the value range of θ is 90° to 180°; further optimized to 90° to 135°.

[0008] Further, the value range of the tool angles α + β of the saw teeth is 70° to 85°; further optimized to 75° to 80°.

[0009] By optimizing the number, distribution, and angle of the arc-shaped liquid storage grooves, it is ensured that the cutting fluid can be evenly distributed and effectively enter the saw kerf, further enhancing the cooling effect and improving the stability of the sawing process at the same time; the optimized tool angle can effectively improve the sawing efficiency and reduce the wear of the saw teeth, further extending the service life of the saw blade.

[0010] Furthermore, the surface of the arc-shaped liquid storage groove is chemically heat-treated to improve its corrosion resistance.

[0011] Furthermore, diversion grooves are also provided between the arc-shaped liquid storage grooves.

[0012] Furthermore, the thickness of the band saw blade is B, and diversion grooves are provided in the thickness direction of the band saw blade. The depth δ of the diversion grooves ranges from 1 / 10B to 1 / 6B.

[0013] The design of the diversion grooves further enhances the fluidity and cooling effect of the cutting fluid, ensures that the cutting fluid can quickly reach the cutting area of the saw teeth, and further reduces the cutting temperature.

[0014] Furthermore, the surface of the diversion grooves is chemically heat-treated to improve its corrosion resistance.

[0024] See Figures 1 to 5 , the embodiments of this application are written in a progressive manner.

[0025] An efficient sawing band saw blade 10, the band saw blade has a sawtooth band; the sawtooth band is in a long strip shape, and a plurality of sawteeth 11 are arranged in sequence along the length direction of the band saw blade, and tooth grooves are formed between adjacent sawteeth, and arc-shaped liquid storage grooves are arranged on the tooth groove contour 12.

[0026] For the efficient sawing band saw blade proposed in this application, by arranging arc-shaped liquid storage grooves on the tooth groove contour, it can effectively store cutting fluid and guide it into the saw kerf, solve the problem that it is difficult for the cutting fluid to reach the middle of the saw kerf in traditional sawing, significantly improve the cooling effect of the sawteeth, and extend the service life of the saw blade.

[0027] This application Figure 1 In the band saw blade shown, the sawtooth band is provided with eight sawteeth; it can be understood that the number of multiple sawteeth included in the band saw blade of this application can be conventionally set by those skilled in the art according to actual needs.

[0028] Such as Figure 2 shown, the tooth groove contour includes a plurality of continuous arc segments, which are arc segments with radii of R1, R2, R3, and R5 respectively.

[0029] The tooth groove contour and arc-shaped liquid storage grooves designed above are conducive to storing cutting fluid and guiding it into the saw kerf, and significantly improve the cooling effect of the sawteeth.

[0030] In the high-speed sawing working condition operation experiment, it can be repeatedly observed that for the band saw blade with the special tooth profile structure of this application, the protrusion on the rake face will form a liquid storage space with the chip to obtain the effect of enhancing the infiltration cooling of the rake face during the cutting process; see Figure 5 the intercepted diagram of the sawing operation experiment effect shown.

[0031] See Figure 2, the diameter of the arc-shaped liquid storage tank is d, and the center distance between adjacent arc-shaped liquid storage tanks is L. The embedding contour arc angle of the arc-shaped liquid storage tank is 360° - θ, where the value range of θ is 90° to 180°; further optimized to 90° to 135°; this structural design ensures that the cutting fluid can be evenly distributed and effectively enter the saw kerf, further enhancing the cooling effect.

Preferably, in the tooth groove contour of adjacent saw teeth, the entire diversion groove has a connecting groove section and a transition groove section. The connecting groove section connects adjacent arc-shaped liquid storage tanks, and the transition groove section extends along both sides of the arc-shaped liquid storage tank.

[0035] Furthermore, the thickness of the band saw blade is B, and a diversion groove is provided in the thickness direction of the band saw blade. The value range of the depth δ of the diversion groove is 1 / 10B to 1 / 6B; see Figure 3 and Figure 4 .
