[0002] Wire saw cutting is a technology that uses a wire saw to cut materials. The diamond wire saw cutting device uses diamond wire as the cutting medium, and generates cutting motion by driving the diamond wire to continuously grind against the object to be cut. Since diamond has extremely high hardness and wear resistance, it is suitable for cutting a variety of materials, such as stone, reinforced concrete, metal, etc. However, it is very troublesome to adjust the tightness of the diamond wire after installing the diamond wire in the existing manual diamond wire saw cutting device. In addition, since only one side of the diamond wire is used for cutting during cutting, the other side of the diamond wire is wasted, which increases the cost of using the material. For this reason, we propose a diamond wire saw cutting device. Utility Model Content

[0024] First, rotate the third hand wheel 38 to drive the second screw 39 to rotate, so that the movable pressure plate 391 is away from the fixed pressure plate 371, and then place one end of the diamond wire 2 between the movable pressure plate 391 and the fixed pressure plate 371, and rotate the third hand wheel 38 in the opposite direction to move the movable pressure plate 391 toward the fixed pressure plate 371 and clamp the diamond wire 2 to complete the installation of the diamond wire 2. Then, rotate the first hand wheel 31 to drive the rotating drum 35, so that the first screw 36 threadedly connected to the rotating drum 35 is displaced parallel to the rotating drum 35, driving the mounting seat 37 to displace to tighten the diamond wire 2.
