Knife rest for multi-wire cutting machine and multi-wire cutting machine with same

Abstract

The invention discloses a knife rest for a multi-wire cutting machine and the multi-wire cutting machine with the same. The knife rest is divided into a knife rest lower body and a knife rest upper body, the knife rest lower body and the knife rest upper body are rotationally connected through a shaft assembly, the shaft body assembly includes a shaft body and a shaft seat assembly, the shaft bodyis rotationally connected with the shaft seat assembly, the shaft body sequentially comprises a lower shaft body, an upper shaft body, a top fixing disc and a pulling head which are coaxial from bottom to top, and the shaft seat assembly comprises a bearing seat, a bearing, an oil seal cover, an oil seal and an end cover. The multi-wire cutting machine includes the above knife rest. According tothe requirement for slicing sheets with different thicknesses, in particular to the requirement for slicing sheets with large thicknesses, the spacing between steel wires is adjusted, the adjusted steel wires are reliably wound in wire troughs, scraping with wire trough walls is not prone to happening, moving to other wire troughs is not prone to happening, accurate cutting is achieved, the cutting precision and efficiency are greatly improved, and the service life of an upper winding main shaft, a lower winding main shaft and the steel wires is prolonged.

Description

technical field [0001] The invention relates to a multi-wire cutting device, in particular to a tool holder for a multi-wire cutting machine and the multi-wire cutting machine. Background technique [0002] Multi-wire cutting is a method of grinding and cutting the hard and brittle materials sent into the processing area into hundreds or even thousands of thin slices through high-speed reciprocating movement of steel wires. Multi-wire cutting machine in the prior art (as figure 1 , figure 2 As shown), the knife holder is integrated, because the two lower winding spindles and the upper winding spindle have the same wire groove, during the process of cutting thicker materials, the wire spacing of the lower layer steel wire is larger, and the steel wire is easy to contact with the wire. Scuffing occurs between the groove wall of the lower winding spindle and the groove wall of the upper winding spindle. In severe cases, wire jumping problems will occur. This will not only ea...

AI Technical Summary

Problems solved by technology

Multi-wire cutting machine in the prior art (as figure 1 , figure 2 As shown), the knife holder is integrated, because the two lower winding spindles and the upper winding spindle have the same wire groove, during the process of cutting thicker materials, the wire spacing of the lower layer steel wire is larger, and the steel wire is easy to contact with the wire. Scuffing occurs between the groove wall of the lower winding spindle and the groove wall of the upper winding spindle. In severe cases, wire jumping problems will occur. This will not only easily damage the upper winding spindle, the lower winding spindle, and the steel wire, but also greatly shorten the winding time of the upper winding. The service life of the wire spindle, the lower winding spindle, and the steel wire is greatly reduced, and the cutting accuracy of thicker materials is greatly reduced. The widest width can only cut 5mm thick products, which is inefficient.
