[0022] The invention will be described in detail below with reference to the drawings and embodiments.

[0023] Such as Figures 1 to 5As shown in the figure, the present invention provides a multi-wire diamond wire stone slab cutting device, which includes a machine vertical fixing frame 1, a machine horizontal fixing frame 2 installed at the top of the machine vertical fixing frame 1, a cylinder 3 fixed on the upper surface of the machine horizontal fixing frame 2 by bolts, a transmission lead screw 4 passing through the end of the machine horizontal fixing frame 2 and arranged inside the machine vertical fixing frame 1, a cutting head device 5 arranged below the machine horizontal fixing frame 2 and connected to the cylinder 3, a guide wheel 6 arranged on the inner side of the cutting head device 5, a main guide wheel motor 7 arranged outside the cutting head device 5, a left tension device 8 and a right tension device 11 arranged in the middle section of the cutting head device 5, a left wire arranging device 9 and a right wire arranging device 12 respectively arranged on one side of the left tension device 8 and the right tension device 11, a reversing wheel 10 arranged at one end of the cutting head device 5 and parallel to the guide wheel 6, a movable support 13 arranged at the lower end of the cutting head device 5, a diamond wire 14 wound around the guide wheel 6, a winding and unwinding motor 15 arranged on the cutting head device 5 and above the left wire arranging device 9 and the right wire arranging device 12, a winding and unwinding wire wheel 16 drivenly connected to the winding and unwinding motor 15, a wire arranging guide wheel 17 arranged on the sides of the left wire arranging device 9 and the right wire arranging device 12, a first transition guide wheel 18 and a second transition guide wheel 19 arranged at one end of the cutting head device 5 and below the main guide wheel motor 7, a lead screw motor 20 arranged on the top of the machine horizontal fixing frame 2 and connected to the upper end of the transmission lead screw 4, and a connector 21 connecting the movable support 13 and the transmission lead screw 4.

[0024] The left tension device 8 and the right tension device 11 have exactly the same structure, including a tension movable base 801, a connecting arm 802 connected to the tension movable base 801, and a tension guide wheel 803 connected to the other end of the connecting arm 802. Both the tension movable base 801 and the tension guide wheel 803 are movably connected to the connecting arm 802 and can be used to adjust the looseness and tightness of the diamond wire 14. There are two sets of wire arranging guide wheels 17, first transition guide wheels 18 and second transition guide wheels 19, which are symmetrically arranged on two sets of cutting head devices 5 respectively, so that the diamond wire 14 on the winding and unwinding wire wheel 16 passes through the wire arranging guide wheel 17, the tension guide wheel 803, the first transition guide wheel 18, the second transition guide wheel 19 and the reversing wheel 10 and is wound around the guide wheel 6. The number of guide wheels 6 is 2, and the two are arranged in parallel at both ends of the cutting head device 5. The guide wheel 6 is provided with a wire winding groove, and under the action of the left tension device, a closed wire mesh is formed.

[0025] The number of machine vertical fixing frames 1 is 4, and the number of machine horizontal fixing frames 2 is 2. The machine vertical fixing frames 1 are connected to the machine horizontal fixing frames 2 by bolts to form an integral bracket. The bolt connection is convenient for disassembly and transportation. The cutting head device 5 includes a cutting head bracket 501 and a cutting head base 502 arranged at the lower end of the cutting head bracket 501. The cutting head base 502 is connected to the movable support 13 by bolts, and there are two sets of cutting head devices 5. The number of main guide wheel motors 7 is 2, and both are motors with the same frequency.

[0026] The cylinder 3 includes a cylinder base plate 301 mounted on the mechanical lateral fixing frame 2, a cylinder support rod 302 connected to the cylinder base plate 301, a cylinder top plate 303 provided at the upper end of the cylinder support rod 302, and a telescopic rod 304 provided inside the cylinder support rod 302 and bolted to the cutting head device 5. The number of cylinders 3 is 4, which are respectively arranged on the mechanical lateral fixing frame 2 by bolts. The cutting head device 5 balances its own weight through the action of the cylinders, so that the main pulley motor can independently bear the acting force of stone cutting. There are 4 driving lead screws 4 and lead screw motors 20 respectively. Each driving lead screw 4 is driven by a separate lead screw motor 20, so that the cutting head device on the movable support 13 moves up and down along with the driving lead screw 4.

[0027] The wire winding and unwinding motors 15 and wire winding and unwinding wheels 16 are in 2 groups, which are respectively arranged on two sets of cutting head devices 5, with one group for wire winding and the other group for wire unwinding.

[0028] This equipment adopts an advanced digital control system to realize the fully automatic cutting process. The equipment has a unique programming interface developed by itself. This equipment has a unique cutting process and can perform fine large plate cutting on large block stones.

[0029] When the equipment is in use, first, the diamond wire 14 wound around a set of wire winding and unwinding wheels 16 sequentially passes through the wire arranging guide pulley 17, the tension guide pulley 803, the first transition guide pulley 18, the second transition guide pulley 19 and the reversing pulley 10 and winds around the two guide pulleys 6, and finally returns to the other set of wire winding and unwinding wheels 16 sequentially through the second transition guide pulley 19, the first transition guide pulley 18, the tension guide pulley 803 and the wire arranging guide pulley 17 on the other side, forming a closed loop.

[0030] When the equipment starts, the two groups of wire winding and unwinding motors 15 and wire winding and unwinding wheels 16 installed on the cutting head device 5 start simultaneously, so that the diamond wire 14 wound around a set of wire winding and unwinding wheels 16 sequentially passes through the wire arranging guide pulley 17, the tension guide pulley 803, the first transition guide pulley 18, the second transition guide pulley 19 and the reversing pulley 10 and winds around the two guide pulleys 6. After starting for a period of time, under the action of the left tension device 8, the right tension device 11, the left wire arranger 9 and the right wire arranger 12, the two guide pulley grooves 6 will be covered with the diamond wire 14, forming a closed wire net.

[0031] At this time, under the action of the digital control system, the device will simultaneously start the cylinder 3, the main driving wheel motor 7 and the lead screw motor 20. Since the cutting head device 5 is installed on the movable support 13, and the movable support 13 is connected to the transmission lead screw 4 through the connector 21. Thus, the cutting head device 5 moves downward, and at the same time, the telescopic rod 304 on the cylinder 3 stretches downward to balance the self-weight of the cutting head device 5, so that the main driving wheel motor 7 only needs to bear the acting force of cutting the stone. At this time, under the action of the main driving wheel motor 7, the left tension device 8, the right tension device 11, the left wire arranging device 9 and the right wire arranging device 12, the diamond wire 14 continuously moves from one set of wire winding and unwinding wheels 16 to another set of wire winding and unwinding wheels 16, achieving the effect of cutting the stone. After this group of stones is cut, the cutting head device 5 returns to the starting position under the action of the moving cylinder 3 and the lead screw motor 20.

[0032] The equipment has a high degree of automation, improves production efficiency, improves the working environment, has a large number of slices cut at one time, and reduces production costs.

[0033] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the scope of the patent and protection of the present invention should be subject to the appended claims.
