detailed description

Below in conjunction with embodiment, the utility model is described in detail: the present embodiment is implemented on the premise of the utility model technical scheme, has provided detailed implementation and concrete operation process, but the protection scope of the present utility model is not limited to the following Example.

As shown in Figures 1 to 4, a wire sawing machine for cutting out graphite blocks includes a frame 1 and a wire saw blade 4. The lower surface of the groove is provided with a workbench 11, and the workbench 11 extends to the outside of the frame 1. The lower part of the frame 1 is provided with a driving wheel 2, and the side of the driving wheel 2 is provided with a lower outer expansion wheel 3 near the working area. The upper part inside the frame is coaxially provided with the driven wheel 6 with the driving wheel 2, and the upper outer expansion wheel 5 is arranged coaxially with the lower outer expansion wheel 3 at the upper part of the frame. Through the driving wheel 2, the driven wheel 6, the upper outer expansion wheel 5 and the lower outer expansion wheel 3, a wire saw blade tensioning device 7 is arranged above the frame 1;

Workbench 11 below is provided with compression motor 13, and compression motor 13 bottom is provided with guide wheel, and compression motor 13 top is provided with and telescopic drive shaft 12, and guide wheel drives telescopic drive shaft 12 to slide left and right, and telescopic drive shaft It penetrates the workbench 11 and extends to the top of the workbench 11; the upper side wall of the frame 1 is fixedly provided with a driven shaft base, and a driven pressing shaft 9 coaxial with the telescopic drive shaft 12 is arranged in the driven shaft base , a driven compression shaft locking device 8 is arranged above the driven shaft base, the graphite block is arranged between the telescopic driving shaft 12 and the driven compression shaft 9, and the telescopic driving shaft 12 and the driven compression shaft 9 A compression disc 14 is provided at the contact between the end and the graphite surface, and anti-skid teeth are provided on the compression disc 14; a process hole is provided at the edge of the graphite block, and a spacer 10 is provided between the lower surface of the graphite block and the workbench.
