Provided in the present invention are a large multi-wire cutting machine frame and a downward-pressing multi-wire cutting device. The large multi-wire cutting machine frame comprises upright post units. Upper ends of two upright post units are connected together by means of longitudinal rod components. Each of the upright post units comprises an upright post body, an upper cross beam and a bottom plate. Two upright post bodies are provided at an interval in a left-right direction. The upper cross beam is connected between upper ends of the two upright post bodies. The bottom plate is connected between lower ends of the two upright post bodies. Various components in the two upright post bodies, the upper cross beam and the bottom plate are integrally connected. Moreover, upright post reinforcing ribs, which are connected to various faces of inner sides of the upright post bodies together, are provided in cavities. The upright post reinforcing ribs are configured to reinforce the upright post bodies and disperse acting forces applied to working faces of the upright post bodies onto other faces of the upright post bodies. The forces on the various faces of the upright post bodies can be dispersed to the entire upright post unit by means of the bottom plate and the upper cross beam. The present invention is used for improving the stability of a frame and saving on manufacturing materials.

CUTTING DEVICE OF STONE SLAB MULTI-WIRE CUTTING MACHINE, AND MULTI-WIRE CUTTING MACHINE
A cutting device of a stone slab multi-wire cutting machine, and a multi-wire cutting machine. The cutting device comprises a frame (2) and a cutting assembly (3). The cutting assembly (3) comprises a first wire winding and unwinding mechanism (32), a second wire winding and unwinding mechanism (33), a first main guide roller (34), a second main guide roller (35), a third main guide roller (36), a fourth main guide roller (37), and a guide roller driving mechanism (38). The four main guide rollers extend in a horizontally longitudinal direction, and both axial ends of each main guide roller are rotatably connected to the frame (2), respectively. The second wire winding and unwinding mechanism (33) is located on the other transverse side of the frame (2). The first wire winding and unwinding mechanism (32) and the second wire winding and unwinding mechanism (33) each comprise a wire winding and unwinding wheel (321), a wire wheel driving component (322), a wire arrangement wheel (323), a wire arrangement device (324), a tension wheel (325), a tension adjustment device (326), a wire feeding and discharging wheel (327) and a wiring mechanism (328). One end of a diamond wire (31) is connected to the wire winding and unwinding wheel (321) and is connected to the corresponding main guide roller after sequentially passing through the wire arrangement wheel (323), the tension wheel (325) and the wire feeding and discharging wheel (327). A wiring distance of the diamond wire (31) can be reduced, such that the wear of the diamond wire (31) can be reduced and the occurrence of wire breakage is reduced.

The present invention relates to the field of multi-wire saws. Particularly disclosed is a deformation reducing main guide roller. The main guide roller comprises a guide roller body and a reinforcing assembly. The guide roller body is internally provided with a hollow part extending in the axial direction; the guide roller body is fixedly provided, in the middle of the hollow part, with a pre-tightened part protruding in the direction close to the central axis, a hollow pre-tightening hole extending in the axial direction being formed in the middle of the pre-tightened part. The reinforcing assembly comprises a first part and a second part which can be interlocked with each other. The maximum outer diameters of two clamping heads are greater than the inner diameter of the hollow pre-tightening hole, and the two clamping heads can be respectively pressed against the two axial ends of the pre-tightened part. Interlocking parts of the first part and the second part can pass through the hollow pre-tightening hole in the middle of the pre-tightened part to be interlocked, and, after the interlocking, the two clamping heads clamp the two end faces of the pre-tightened part, thereby applying an axial pre-tightening force to the pre-tightened part. The present invention can resist deformation, and can also save materials used for manufacturing a guide roller and reduce the weight of same, thus being suitable for manufacturing a large-size guide roller required for cutting a large-size slab.

JACKING-TYPE STONE SLAB MULTI-WIRE CUTTING MACHINE HAVING FOUR COLUMNS AND FOUR GUIDE WHEELS
The present invention relates to a jacking-type stone slab multi-wire cutting machine having four columns and four guide wheels. The cutting machine comprises a machine platform and a frame. The frame is provided with a cutting assembly, and the machine platform is provided with a jacking mechanism. The cutting assembly comprises a diamond wire, a first take-up and pay-off mechanism, a second take-up and pay-off mechanism, a first main guide wheel, a second main guide wheel, a third main guide wheel, a fourth main guide wheel, and a guide wheel drive mechanism. The four main guide wheels extend horizontally and are arranged longitudinally, and two axial ends of each main guide wheel are rotatably connected to the frame. One end of the diamond wire is released from the first take-up and pay-off mechanism, and is led in from the first main guide wheel, repeatedly wound around the four main guide wheels in a sequence of the first main guide wheel, the second main guide wheel, the third main guide wheel and the fourth main guide wheel, and finally led out from the second main guide wheel, so that the diamond wire forms a first cutting mesh between the bottom of the third main guide wheel and the bottom of the fourth main guide wheel. The present invention aims to solve the problems of insufficient stability of the cutting machine when cutting large stone slabs, easy breakage of the diamond wire, and water vapor affecting the take-up and pay-off mechanisms.
