Description

Technical Field

[0001] This utility model relates to the field of saw blade equipment technology, specifically to a circular saw blade with a spiral corrugated pattern. Background Technology

[0002] Circular saw blades made of general-purpose materials are mainly used for cutting low-hardness carbon steel and non-ferrous metal bars and pipes; circular saw blades made of superhard materials are used for milling difficult-to-cut materials (heat-resistant iron, stainless steel, and high-hardness steel). Saw blades can be divided into: diamond saw blades for stone cutting; high-speed steel saw blades for metal cutting; and carbide saw blades for cutting solid wood, furniture, artificial boards, aluminum alloys, aluminum profiles, radiators, plastics, and PVC.

[0003] Chinese utility model CN204076409U discloses an "electric circular saw woodworking circular saw blade", which has a high cutting speed and good auxiliary functions such as positioning, chip removal and chip cutting by directly making the blade head on the saw teeth. However, when existing cold saw circular saw blades are used, when the saw blade is damaged, the entire cold saw circular saw blade is usually replaced, which increases the economic cost. At the same time, the device is noisy because it does not have a corresponding noise reduction structure. Utility Model Content

The noise reduction structure 3 includes a first hole 31 and a second hole 32. The first hole 31 is located on the outer periphery of the ring saw blade 1 and near the cutter heads 11. A plurality of second holes 32 are arranged circumferentially on the outer periphery of the ring saw blade 1. The first hole 31 and the second hole 32 are connected to each other and form a noise reduction chamber 33. A noise reduction end 34 is disposed in the noise reduction chamber 33. The mounting plate 4 includes a first plate body 41 and a second plate body 42. The first plate body 41 and the second plate body 42 are detachably connected to both sides of the ring saw blade 1.

[0031] In this embodiment, a cutting head 11 is provided on the outer periphery of the ring saw blade 1 for cutting objects, and an extension plate 2 is provided on the inner wall of the ring saw blade 1 to facilitate subsequent connection with the first disc body 41 and the second disc body 42 via external bolts. A first hole 31 is provided on the outer periphery of the ring saw blade 1 near the cutting head 11, and multiple arc-shaped second holes 32 are provided circumferentially on the front and back sides of the ring saw blade 1. The first hole 31 and the second hole 32 are interconnected, and a noise reduction chamber 33 is formed inside the ring saw blade 1. Through the noise reduction end 34 inside the noise reduction chamber 33, noise can be effectively absorbed and reduced, thereby achieving a good noise reduction effect.

[0032] In one embodiment, please refer to Figure 1 - Figure 4 To improve the working efficiency of the ring saw blade 1, multiple chip removal holes 12 are provided on the outer circumference of the ring saw blade 1.

[0034] In one embodiment, please refer to Figure 1 - Figure 7 To facilitate assembly between the first disc 41 and the second disc 42, the extension plate 2 has multiple circumferentially oriented positioning grooves 21 on both the front and back sides. First screw holes 22 are provided on both sides of the positioning grooves 21, and the first disc 41 and the second disc 42 are threadedly connected to the first screw holes 22. A limiting protrusion 411 is provided on the side of the first disc 41 facing the second disc 42, and a positioning ring 421 is provided on the side of the second disc 42 facing the limiting protrusion 411. A limiting slot 4211 is provided on the positioning ring 421 for the limiting protrusion 411 to extend.

First screw holes 22 are provided on both sides of the positioning grooves 21. Positioning blocks 43 on the first disc 41 and the second disc 42 facilitate the extension of the positioning blocks 43 into the positioning grooves 21. The first screw holes 22 and the second screw holes 44 are aligned. The assembly is achieved by external bolts passing through the first screw holes 22 and the second screw holes 44. This also facilitates replacement by workers in case of subsequent damage. A limiting protrusion 411 is provided on the first disc 41, and a positioning ring 421 is provided on the second disc 42. An annular limiting slot 4211 is opened on the positioning ring 421 to facilitate the extension of the limiting protrusion 411 into the limiting slot 4211, thus completing the assembly of the first disc 41 and the second disc 42.

[0036] In one embodiment, please refer to Figure 1 - Figure 7 To improve the noise reduction efficiency of the device, the cross-section of the noise reduction chamber 33 is serpentine, and there are multiple noise reduction chambers 33. Each noise reduction chamber 33 is provided with a noise reduction end 34. Each noise reduction end 34 includes two baffles 341 and several noise reduction balls 342.
