Description

Technical Field

[0001] The utility model relates to the field of saw blades, and more specifically, to a metal cold and hot cutting saw blade. Background Art

[0002] Metal cold and hot cutting saw blades are a commonly used cutting tool in the metal processing industry, and are mainly used for sawing various metal products, such as metal bars, metal pipes, steel and other metal products. Since the production lines in the metal processing industry are mostly continuous production, when the cold and hot cutting saw blades continuously cut metal materials, the saw blades will generate a lot of heat after a long period of friction. If this heat cannot be dissipated in time, the cutting quality will be reduced. When the heat is too high, the cutting edge may melt, burn or heat crack, thereby reducing the cutting quality. In severe cases, it will cause the saw blade to deform, affecting the service life of the circular saw blade.

[0003] Based on the above, the purpose of the present invention is to provide a metal cold and hot cutting saw blade to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a metal cold and hot cutting saw blade. The utility model arranges heat dissipation grooves and heat-conducting strips connected to the cutter head on both sides of the saw blade body. When the saw blade cuts metal, the heat generated by the cutter head during the cutting process will be quickly guided to the surrounding area of ​​the saw blade body by the heat-conducting strips, and heat will be exchanged with the air through the heat dissipation grooves during the rotation process, thereby quickly dissipating the heat on the cutter head, preventing the reduction in cutting quality due to long-term use and extending the service life of the saw blade.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a metal cold and hot cutting saw blade, including a saw blade body and a plurality of cutter heads, the saw blade body is provided with a rotating shaft hole and a plurality of transmission holes, both sides of the saw blade body are provided with heat dissipation grooves, the heat dissipation grooves on both sides are provided with heat conducting strips with the same number as the cutter heads, and one end of the heat conducting strip is fixedly connected to the cutter head.

[0006] By adopting the above technical solution, when the saw blade cuts metal, the heat generated by the cutter head during the cutting process will be quickly guided to the surrounding area of ​​the saw blade body by the heat conductive strip, and heat will be exchanged with the air through the heat dissipation groove during rotation, thereby quickly dissipating the heat on the cutter head, preventing the cutting quality from being reduced due to long-term use, and extending the service life of the saw blade.

[0007] The utility model is further configured as follows: the cutter head is a metal ceramic blade.

[0008] The utility model is further configured that: the heat conducting strip is made of copper alloy.

[0009] The utility model is further configured as follows: the heat conducting strip is arranged in an arc shape, and an oblique angle is arranged on the heat conducting strip, and the inclination angle of the oblique angle gradually increases from one end close to the cutter head to the other end.

[0010] The utility model is further configured as follows: a chip removal groove is arranged on one side of the saw blade body close to the cutter head.

[0011] In summary, the utility model has the following beneficial effects:

[0012] The utility model provides heat dissipation grooves and heat-conducting strips connected to the cutter head on both sides of the saw blade body. Since the cutter head is a metal ceramic blade, the metal ceramic blade has a high high temperature resistance, making the saw blade more suitable for long-term continuous cutting. Since the thermal conductivity of the metal ceramic blade is low, the heat generated by high-speed cutting will be taken away with the chips, and it is not easy to generate heat itself. During the long-term cutting process, the heat generated by the cutter head will be quickly guided to the surrounding of the saw blade body by the copper alloy heat-conducting strip with high thermal conductivity, and heat will be exchanged with the air through the heat dissipation groove during rotation, thereby quickly dissipating the heat on the cutter head, preventing the situation where the cutting quality is reduced due to long-term use, and extending the service life of the saw blade. The chip removal groove can quickly discharge the chips to prevent the chips from accumulating at the cutter head and reducing the cutting performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] The utility model is described in detail below in conjunction with the accompanying drawings.

[0022] A metal cold and hot cutting saw blade, such as Figures 1 to 4 As shown, it includes a saw blade body 1 and a plurality of cutter heads 2 fixedly connected to the saw blade body, the cutter head 2 is a metal ceramic blade, the saw blade body 1 is provided with a shaft hole 3 and a plurality of transmission holes 4, heat dissipation grooves 5 are provided on both sides of the saw blade body 1, and the heat dissipation grooves 5 on both sides are fixedly connected with heat conducting strips 6 of the same number as the cutter head 2, the heat conducting strips are made of copper alloy, one end of the heat conducting strip 6 is fixedly connected to the cutter head 2, the heat conducting strip 6 is arranged in an arc shape, and a bevel 7 is processed on the heat conducting strip 6, the inclination angle of the bevel 7 gradually increases from one end close to the cutter head 2 to the other end, and a chip removal groove 8 is provided on the side of the saw blade body 1 close to the cutter head 2.

[0023] Since the cutter head 2 is a metal ceramic blade, the metal ceramic blade has a high high temperature resistance, making the saw blade more suitable for long-term continuous cutting. Moreover, since the thermal conductivity of the metal ceramic blade is low, the heat generated by high-speed cutting will be taken away with the chips, and the metal ceramic blade itself is not easy to heat up. The chip groove 8 can quickly discharge the chips to prevent the chips from accumulating at the cutter head 2 and reducing the cutting performance.

[0024] The heat generated on the cutter head 2 during the long-term cutting process will be quickly guided to the whole body of the saw blade body 1 by the copper alloy heat-conducting strip 6 with high thermal conductivity, and heat will be exchanged with the air through the heat dissipation groove 5 during the rotation, thereby quickly dissipating the heat on the cutter head 2, preventing the high temperature accumulation on the cutter head due to long-term use and the reduction of cutting quality, thereby extending the processing time and service life of the saw blade. The arc-shaped heat-conducting strip 6 can increase the contact area with the air, and can also increase the air flow rate on both sides of the saw blade to make the heat exchange efficiency higher. The bevel 7 can further guide the direction of the airflow, reduce the friction resistance between the heat-conducting strip 6 and the air, and make the saw blade's rotation and cutting smoother.

[0025] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
