A gantry type wire saw cutting machine includes a gantry type frame, a wire saw cutting mechanism, a cutting feed mechanism, a wire saw tension control mechanism, a workbench device, and a control console. Referring to Figures 1 to 3, the specific details are as follows:

The gantry frame is composed of a crossbeam 11 and two parallel columns 121,122, and is a gantry structure. There are vertically extending guide rails 131,132 outside the columns 121,122, and the whole frame is installed on the base 14.

The left and right carriages 211 , 212 are movably arranged in the guide rails 131 , 132 through guide wheels 213 . Each wire saw wheel set includes upper and lower two rotatable wire saw wheels, and there are four wire saw wheels 221, 222, 223, 224 in total, wherein the wire saw wheel 221 is the active wire saw wheel, and the rest are driven wire saw wheels. Wheel and wire saw wheel are all rotatably arranged on the left and right planks 211,212 respectively by their respective rotating shafts and bearings. The driving mechanism of the wire saw wheel includes a motor 231 and a transmission mechanism, and the transmission mechanism can adopt common transmission structures such as gear transmission and belt transmission. The motor 231 is electrically connected to the frequency converter. The control principle and circuit structure of the frequency converter are in the prior art, and will not be repeated here. The wire saw 24 is tensioned on the four wire saw wheels, and the positioning guide wheel 27 plays the role of positioning the wire saw 24. The active wire saw wheel 221 is driven by the motor 231 and the transmission mechanism, thereby driving the wire saw 24 and other wire saw wheels to rotate to realize cutting of the stone 7 . Protective cover 26 is connected on dragging board, and cover covers outside the wire saw wheel, plays a safety protection effect, and protective cover 26 can be opened and closed movably, is convenient to loading and unloading, replaces wire saw.

Referring to Fig. 4, the wire saw tension adjustment mechanism 3 includes a wire saw wheel frame 31 and a cylinder 32, one end of the wire saw wheel frame 31 is articulated on the carriage through a hinge 33, and the other end is connected to the piston rod of the cylinder 31, The air cylinder 31 is supported on the carriage through the bearing portion 34, and the air cylinder 31 is connected with the pneumatic system. A driven wire saw wheel is arranged on the wire saw wheel frame 31. The wire saw wheel frame 31 is pushed by the air cylinder 31 to adjust the tension of the wire saw 24 .

Referring to Fig. 5, the working principle of the above-mentioned pneumatic system is as follows: compressed air enters the pressure regulating valve 62 from the inlet valve 61 to form a suitable stable pressure, passes through the one-way valve 63, is distributed by the manual reversing valve 64, and then passes through the one-way throttling valve. Valve 65 feeds into cylinder 31, pushing its piston rod to move. Throttle valve 65 can control the air supply speed. The pressure switch 66 in the figure constitutes the air pressure detection device. When the pressure of the compressed air is too low in the cutting process, the tension of the wire saw 24 cannot be guaranteed, and the pressure switch 66 sends a signal to the computer control system to stop the machine. According to the material of the stone, the compressed air pressure is regulated by the pressure regulating valve 62 to adjust the tension of the wire saw 24 . The advantage of adopting the pneumatic system for adjustment is that the cylinder 32 uses compressed air as the medium and has good elasticity, so that the movement of the wire saw 24 is more balanced.
