The centrifugal pump 9 is connected and communicated with a water pipe 10, which extends to the outside of the mounting shell 1. A transparent plate 22 is provided on the front side of the mounting shell 1, and the transparent plate 22 facilitates direct viewing of the water volume inside the mounting shell 1. A protective shell 23 is provided on the support seat 501, and the protective shell 23 protects the motor on the electric saw 6 to prevent cutting debris from entering the interior of the motor.

[0024] When it is necessary to cut the steel rod into sections, first place the steel rod on the transport rack 2, push the steel rod forward to the appropriate position, start the first motor 3 and the electric saw 6, and the output shaft of the first motor 3 rotates to drive the gear 4.

The electric saw 6 starts to operate and cuts the steel rod into sections. After the section cutting is completed, start the centrifugal pump 9. The centrifugal pump 9 runs to draw water inside the mounting shell 1 into the water pipe 10, and then sprays it on the blade of the electric saw 6 through the water pipe 10, thereby cooling the blade to prevent the blade from losing hardness at high temperature, resulting in a decrease in cutting efficiency and accelerated blade wear.
