Description

Technical Field

[0001] The utility model relates to the technical field of slotting saw blades, in particular to a diamond slotting saw blade. Background Art

[0002] A diamond slotting saw blade is a professional cutting tool, which is mainly used for slotting or cutting on hard materials such as concrete, asphalt, etc. In the prior art, a diamond slotting saw blade is generally a single saw blade structure. During the use of such a saw blade, the cutting and slotting efficiency is low, and when the saw blade breaks, the saw blade needs to be replaced as a whole, and the use cost is relatively high. For this reason, we propose a diamond slotting saw blade. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide a diamond slotting saw blade, which forms a three-piece superimposed and distributed structural design through the arrangement of a slotting saw blade assembly and a saw blade structure, and is locked into a whole through bolts. The structure of the three saw blades being staggered, superimposed and locked improves the efficiency of slotting and increases the durability of the saw blade. The structure of the saw blade combination allows a single saw blade to be replaced individually when it is worn, and the cost of use is relatively low.

[0004] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0005] A diamond slotting saw blade, comprising:

[0006] A slotting saw blade assembly, the slotting saw blade assembly comprising a first saw blade, a second saw blade attached to the bottom surface of the first saw blade, and a third saw blade attached to the bottom surface of the second saw blade;

[0007] The saw blade structure includes a heat dissipation hole opened on the surface of the first saw blade and a mounting hole opened in the middle position of the first saw blade.

[0008] As a preferred solution of the diamond slotted saw blade described in the utility model, the slotted saw blade assembly further includes a threaded bolt arranged above the first saw blade and a hexagonal slot formed at the top of the threaded bolt.

[0009] As a preferred solution of the diamond slotted saw blade described in the utility model, the saw blade structure further includes a circular groove formed on the surface of the first saw blade and a threaded hole formed in the circular groove.

[0010] As a preferred solution of the diamond slotted saw blade described in the utility model, the threaded bolt passes through the threaded hole, and the top end of the threaded bolt is embedded in the circular groove.

[0011] As a preferred solution of the diamond slotted saw blade described in the utility model, wherein the saw blade structure further includes notched grooves formed at both ends of the first saw blade;

[0012] There are two notches, and the two notches are symmetrically arranged at the center line of the first saw blade.

[0013] As a preferred embodiment of the diamond slotted saw blade of the utility model, the first saw blade, the second saw blade and the third saw blade are arranged in a staggered manner;

[0014] Wherein, the structures of the first saw blade, the second saw blade and the third saw blade are equal.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. By setting up the slotted saw blade assembly and saw blade structure, a three-blade superimposed and distributed structural design is formed, and the three saw blades are locked into a whole through bolts. The staggered, superimposed and locked structure of the three saw blades improves the efficiency of slotting and increases the durability of the saw blades. In addition, the structure of the saw blade combination can be replaced individually when a single saw blade is worn, and the cost of use is relatively low.

[0017] 2. By setting the notch groove, the impact force during the rotary grooving process is increased, further improving the grooving efficiency of the saw blade.

[0018] During specific use, the first saw blade, the second saw blade and the third saw blade are placed on top of each other and are staggered. At this time, the threaded bolts are threaded in the superimposed threaded holes in turn until the first saw blade, the second saw blade and the third saw blade are locked together. At this time, the top of the threaded bolt is embedded in the circular groove to maintain the flatness and consistency of the saw blade appearance. The threaded bolts are distributed in a ring shape, with a total of six. This multi-point positioning and locking can prevent the saw blades from moving out of place during use. The distribution of the heat dissipation holes is used to dissipate heat during the cutting and grooving process to prevent heat accumulation from causing a decrease in the strength of the saw blade. The three saw blades distributed in this way are staggered and can be replaced independently, which improves the grooving efficiency and reduces the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The utility model provides a diamond slotting saw blade, which forms a structural design of three superimposed and distributed blades through the provision of a slotting saw blade assembly and a saw blade structure, and is locked into a whole through bolts. The structure of the three saw blades being staggered, superimposed and locked improves the efficiency of slotting and increases the durability of the saw blades. In addition, the structure of the saw blade combination can be replaced individually when a single saw blade is worn, and the use cost is relatively low.

[0030] Figure 1-4 The figure shows the overall structure of a diamond slotting saw blade according to the present invention. Figure 1-4 The main body of a diamond slotting saw blade in this embodiment includes: a slotting saw blade assembly and a saw blade structure.

[0031] The slotted saw blade assembly is used to form a stacked structure. Specifically, the slotted saw blade assembly includes a first saw blade 11, a second saw blade 12 attached to the bottom surface of the first saw blade 11, and a third saw blade 13 attached to the bottom surface of the second saw blade 12.

[0032] During specific use, the first saw blade 11, the second saw blade 12 and the third saw blade 13 are placed one on top of the other and staggered at 120 degrees, which can improve the efficiency of cutting and grooving.

[0033] The saw blade structure is used in combination with the slotted saw blade assembly to achieve locking integration. Specifically, the saw blade structure includes a heat dissipation hole 21 provided on the surface of the first saw blade 11 and a mounting hole 23 provided in the middle of the first saw blade 11.

[0034] The slotted saw blade assembly further includes a threaded bolt 14 disposed above the first saw blade 11 and a hexagonal slot 15 formed at the top of the threaded bolt 14;

[0035] The saw blade structure further includes a circular groove 24 formed on the surface of the first saw blade 11 and a threaded hole 25 formed in the circular groove 24;

[0036] The threaded bolt 14 passes through the threaded hole 25, and the top end of the threaded bolt 14 is embedded in the circular groove 24;

[0037] During specific use, the threaded bolt 14 is threadedly inserted into the superimposed threaded holes 25 in sequence until the first saw blade 11, the second saw blade 12 and the third saw blade 13 are locked together. At this time, the top of the threaded bolt 14 is embedded in the circular groove 24 to maintain the flatness and consistency of the appearance of the saw blade. The threaded bolts 14 are distributed in a ring shape, with a total of six. Such multi-point positioning and locking can avoid the saw blade from moving out of place during use. The distribution of the heat dissipation holes 21 is used to dissipate heat during the cutting and grooving process to avoid the situation where heat accumulation causes the saw blade strength to decrease. The three saw blades distributed in this way are staggered and can be replaced independently, thereby improving the grooving efficiency and reducing the cost of use.

[0038] Furthermore, the saw blade structure also includes notch grooves 22 formed at both ends of the first saw blade 11;

[0039] There are two notch grooves 22, and the two notch grooves 22 are symmetrically arranged at the midline position of the first saw blade 11;

[0040] During specific use, the notched groove 22 increases the impact force during the rotary notching process, further improves the notching efficiency of the saw blade, reduces the risk of saw blade breakage, thereby improving the durability and safety of the saw blade, and helps to discharge debris during the cutting process, avoid chip blockage, reduce problems such as broken teeth and cutting lines, and maintain a smooth cutting process.

[0041] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
