Detailed ways

As shown in Fig. 1 and Fig. 2, the beam 2 is installed on the left and right columns 1 by bolts to form the main frame of the multi-rope diamond bead saw of the present invention. Both left and right columns 1 are provided with feed pallets 7, driving wheels 3 are installed on the feed pallets of the right column, and tension pulleys 4 are installed on the feed pallets of the left column. Guide wheels 5 are installed on the board, and more than two rope grooves 15 are evenly distributed on the guide wheels 5 (referring to Fig. 3, the present embodiment provides 5 rope grooves), and driving wheels 3 are also evenly distributed with rope grooves 15. Multiple identical grooves to process sheets of different thicknesses. The tensioning wheel 4 is connected with the telescopic hydraulic cylinder 6 installed on the feed pallet, and the telescopic hydraulic cylinder 6 drives the tensioning wheel 4 to move left and right in the horizontal direction. A beaded rope 14 is connected between the driving wheel 3 and the tension pulley 4, and the processing position of the beaded rope 14 is controlled by the guide wheel 5. Also main motor 8 is installed on the feeding supporting plate of right column, and driving pulley 12 is installed on the main motor 8, and driven pulley 13 is installed on the driving wheel 3. The main motor 8 drives the driving pulley 12 to rotate, the driving pulley 12 drives the driven pulley 13 to rotate, the driven pulley 13 drives the driving pulley 3 to rotate, and the driving pulley 3 drives the tension pulley 4 to rotate through the beaded rope 14. The outer peripheral surfaces of the wheel 3 and the tension wheel 4 form a closed-loop rotary motion, constituting the main motion mechanism of the bead saw.

A feed mechanism consisting of a feed motor 9 , a feed transmission shaft 10 and a feed screw 11 is installed on the beam 2 . Feed screw 11 forms a pair of leading screw nut pair with the nut that is installed on the feed pallet 7 . The feed motor 9 drives the two feed transmission shafts 10 to rotate through a pair of bevel gears, and the two feed transmission shafts 10 respectively drive the feed screw 11 to rotate through a pair of bevel gears, and the feed screw 11 passes through the feed screw The nut pair drives the left and right two feed supporting plates 7 to move up and down along the columns installed respectively, so as to realize the feed motion of the bead saw. The main motor 8 and the feed motor 9 are AC asynchronous motors with variable frequency speed regulation.

The tensioning pulley 4 adopts a split structure. The single tensioning pulleys with a rope groove are independent of each other. Each tensioning pulley is connected with a hydraulic cylinder. The hydraulic cylinder is fixed on the mounting bracket of the tensioning pulley 4, and its piston The rod is connected to the inner ring of the monolithic tensioner. Start the hydraulic cylinder, so that the hydraulic cylinder pushes the inner ring of the tensioning wheel according to the set pressure value, and drives each piece of tensioning wheel to move, so as to realize the individual tensioning of each beaded rope. Each tension wheel is all supported on the beaded rope 14, and the length of the beaded rope 14 is changed to make the beaded rope 14 have a suitable tension value, so that the tension value of the beaded rope 14 is always in a dynamic equilibrium state. Driving wheel 3 and two guide wheels 5 adopt integral structure.
