Cutting saw blade special for paint-free plate

Abstract

The utility model discloses a special cutting saw blade for a paint-free plate, which comprises a circular saw blade body, saw teeth are formed on the periphery of the body, the saw teeth are divided into six groups, each group of saw teeth comprises eighteen saw teeth, the pitch of the first sixteen saw teeth is not more than 5mm, and the pitch of the seventeenth saw tooth and the eighteenth saw tooth is not less than 7.5 mm. According to the cutting saw blade special for the paint-free plate, the high-density sawteeth with the tooth pitch not larger than 5 mm mainly solve the problem of edge cracking in the cutting process of the paint-free plate, the seventeenth sawteeth and the eighteenth sawteeth are long flat teeth with the tooth pitch not smaller than 7.5 mm, the effect of accurately cutting the cut fracture surface again is achieved, the cut fracture surface is smoother, and the service life of the cutting saw blade is prolonged. And a large chip removal groove structure formed by the wide tooth pitches can improve the chip removal capacity, reduce the cutting resistance, increase the cutting sharpness and further reduce the cutting edge cracking problem of the paint-free plate.

Description

Technical Field

[0001] The utility model relates to the technical field of cutting circular saw blades, in particular to a special cutting saw blade for cutting paint-free boards. Background Art

[0002] As we all know, a large pitch of saw blade teeth has good chip removal and low cutting resistance, but it is also easy to cause the paint-free board to have cracked edges; while a pitch that is too small has poor chip removal and increased cutting resistance, which can easily cause cracked edges prematurely after a period of use. The current paint-free board special saw blade teeth are generally composed of ladder teeth and flat teeth, and the pitch between the teeth is generally between 7.0 and 9.4 mm. In actual use, there is still the problem of cracked edges. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a special cutting saw blade for paint-free boards which can reduce the problem of edge bursting during cutting.

[0004] The technical solution adopted to solve the above technical problems is: a special cutting saw blade for paint-free boards, including a circular saw blade body, with saw teeth formed on the periphery of the body, characterized in that: the saw teeth are divided into six groups, each group of saw teeth contains eighteen saw teeth, wherein the tooth pitch of the first sixteen saw teeth is not greater than 5mm, and the tooth pitch of the seventeenth and eighteenth saw teeth is not less than 7.5mm.

[0005] On the basis of the above, the first sixteen saw teeth are arranged in a sequence of alternating flat teeth and ladder teeth.

[0006] On the basis of the above, the seventeenth and eighteenth saw teeth are configured as long flat teeth.

[0007] The beneficial effects brought about by the use of the utility model: the high-density saw teeth with a pitch of no more than 5mm of the special cutting saw blade for paint-free boards of the utility model mainly solve the problem of edge bursting when cutting paint-free boards. The seventeenth and eighteenth saw teeth are long flat teeth with a pitch of no less than 7.5mm, which play the role of re-fine cutting on the cut section, making the cut section smoother, and the large chip groove structure formed by the wide tooth pitch can increase the chip removal capacity and reduce the cutting resistance, increase the cutting sharpness, and further reduce the problem of edge bursting when cutting paint-free boards.

[0013] like Figure 1-3 As shown, a special saw blade for cutting paint-free boards includes a circular saw blade body 1, and saw teeth 1.1 are formed around the body 1. In the utility model, the saw teeth 1.1 are divided into six groups, each group of saw teeth 1.1 includes eighteen saw teeth 1.1, wherein the tooth pitch A of the first sixteen saw teeth 1.1 is not greater than 5mm, and the tooth pitch B of the seventeenth and eighteenth saw teeth is not less than 7.5mm.

[0014] In this embodiment, the first sixteen saw teeth 1.1 are arranged as flat teeth and ladder teeth alternately in sequence. The seventeenth and eighteenth saw teeth are arranged as long flat teeth.

[0015] The high-density saw teeth 1.1 with a pitch A not greater than 5mm are mainly used to solve the problem of edge bursting when paint-free boards are cut. The seventeenth and eighteenth saw teeth 1.1 are long flat teeth with a pitch B not less than 7.5mm, which play a role in re-fine cutting of the cut section, making the cut section smoother. The large chip groove structure formed by the wide tooth pitch can increase the chip removal capacity and reduce the cutting resistance, increase the cutting sharpness, and further reduce the problem of edge bursting when paint-free boards are cut.

[0016] Figure 4 This is a real picture of the paint-free board cut by a traditional cutting saw blade; Figure 5 This is a real shot of a paint-free board cut by the paint-free board special cutting saw blade of the utility model. By comparison, it can be seen that Figure 4 The cracking phenomenon of the cut edge of the paint-free board is obvious. Figure 5 The cracking phenomenon of the cut edges of the paint-free board has been significantly improved.
