[0021] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0022] Combined with Figures 1 - 3 , a temperature control structure of a metal cold and hot cutting circular saw blade includes a saw blade body 1, and a protective cover 2 movably arranged above the saw blade body 1.

[0023] Next, the present utility model will be further described in conjunction with the embodiments.

[0024] Embodiment 1:

[0025] Please refer to Figures 1 - 5, the cooling component 5 includes a connecting pipe 51 fixedly penetrating through the bottom end of the cooling box 4, a diversion block 52 fixedly connected to the outer surface of the connecting pipe 51, a liquid receiving seat 53 fixedly connected to the outer surface of the connecting pipe 51, a liquid outlet pipe 54 fixedly connected to the bottom end of the liquid receiving seat 53, and a drainage platform 55 fixedly connected inside the connecting pipe 51. A first liquid outlet 511 is formed on the outer surface of the connecting pipe 51. The diversion block 52 is arranged directly below the first liquid outlet 511. The bottommost end of the drainage platform 55 is arranged below the first liquid outlet 511. A first groove 531 is formed on the upper surface of the liquid receiving seat 53, and a second liquid outlet 532 is formed on the lower surface of the liquid receiving seat 53. The first groove 531 communicates with the second liquid outlet 532. The liquid outlet pipe 54 passes through the through hole 21. The cooling box 4 contains a cooling liquid. Under the action of gravity, the cooling liquid flows towards the connecting pipe 51. The drainage platform 55 helps to collect and guide the cooling liquid towards the first liquid outlet 511, ensuring uniform and continuous flow of the cooling liquid. At the same time, the drainage platform 55 has the effect of slowing down the flow rate of the cooling liquid. The cooling liquid flowing out from the first liquid outlet 511 flows into the first groove 531 under the action of the diversion block 52, and finally flows towards the outer surface of the saw blade body 1 through the second liquid outlet 532 and the liquid outlet pipe 54, facilitating the rapid absorption and removal of the heat generated during the cutting of the saw blade body 1, effectively controlling the temperature rise of the saw blade body 1, and preventing problems such as a decrease in hardness, softening of the cutting edge, and deformation caused by overheating of the saw blade body 1.

[0026] A plurality of groups of the first liquid outlet 511, the second liquid outlet 532, and the diversion block 52 are provided. A sealing plug 512 is movably connected inside each group of the first liquid outlets 511. By controlling the connection between the sealing plug 512 and the first liquid outlet 511, it is convenient to flexibly control the opening and closing of each group of the first liquid outlets 511, and thus convenient to control the flow rate of the cooling liquid.

[0027] The shockproof component 3 includes a support seat 31 fixedly connected to the top end of the protective cover 2, a shock-absorbing spring 32 arranged inside the support seat 31, a first connection seat 33 arranged at the top end of the shock-absorbing spring 32, and a first fixing block 34 fixedly connected to the top end of the first connection seat 33. A second groove 311 is formed on the upper surface of the support seat 31. One end of the shock-absorbing spring 32 is fixedly connected to the bottom end of the inner wall of the second groove 311, and the other end of the shock-absorbing spring 32 is fixedly connected to the first connection seat 33. The shock-absorbing spring 32 is convenient for absorbing and dispersing the vibration energy generated during the cutting process, thereby reducing the influence of vibration on the first connection seat 33 and the cooling box 4.

[0028] A second connecting seat 41 is fixedly connected to the bottom end of the cooling box 4. A second fixing block 411 is fixedly connected to the outer surface of the second connecting seat 41. A limiting groove 341 is formed on the upper surface of the first fixing block 34. The second connecting seat 41 is fitted into the limiting groove 341. The diameter of the first fixing block 34 is equal to the diameter of the second fixing block 411. A locking bolt 6 is screwed between the first fixing block 34 and the second fixing block 411. When the second connecting seat 41 is fitted into the limiting groove 341, the bottom end of the second fixing block 411 contacts the top end of the first fixing block 34. The second fixing block 411 is fixed to the first fixing block 34 by the locking bolt 6. Removing the locking bolt 6 facilitates separating the cooling box 4 from the first fixing block 34.

[0029] A liquid inlet is formed on the upper surface of the cooling box 4. A sealing cover 42 is movably connected inside the liquid inlet. A sealing gasket is fixedly connected at the connection between the liquid inlet and the sealing cover 42. Opening the sealing cover 42 facilitates replenishing the cooling liquid into the cooling box 4. The sealing gasket helps maintain a good sealing effect and prevent the pollution of the inside of the cooling box 4 by the surrounding environment.

[0030] Both the sealing plug 512 and the sealing gasket are components made of a rubber material. The rubber material has high elasticity, which facilitates closely fitting the contact surface to form an effective sealing barrier.

[0031] During use, opening the sealing plug 512 and controlling the connection between the sealing plug 512 and the first liquid outlet 511 facilitates flexibly controlling the opening and closing of each first liquid outlet 511, and thus facilitates controlling the flow rate of the cooling liquid. Under the action of gravity, the cooling liquid flows towards the connecting pipe 51. The diversion platform 55 helps collect and guide the cooling liquid towards the first liquid outlet 511, ensuring uniform and continuous flow of the coolant. At the same time, the diversion platform 55 has the effect of slowing down the flow rate of the cooling liquid. The cooling liquid flowing out from the first liquid outlet 511 flows into the inside of the first groove 531 under the action of the diversion block 52, and finally flows towards the outer surface of the saw blade body 1 through the second liquid outlet 532 and the liquid outlet pipe 54, facilitating quickly absorbing and taking away the heat generated during the cutting of the saw blade body 1, effectively controlling the temperature rise of the saw blade body 1, and preventing problems such as a decrease in hardness, softening of the cutting edge, and deformation caused by overheating of the saw blade body 1. During the cutting process, the shock-absorbing spring 32 facilitates absorbing and dispersing the vibration energy generated during the cutting process, thereby reducing the impact of vibration on the cooling box 4. When the cooling box 4 needs to be cleaned or maintained, remove the locking bolt 6 and separate the second fixing block 411 from the first fixing block 34, thereby facilitating separating the cooling box 4 and the protective cover 2.
