The upper computer calculates the feeding speed of the lifting table and then sends an instruction to the motor to adjust the rotating speed of the motor, then the feeding speed of the lifting table is adjusted, the feeding speed does not need to be set manually, the feeding speed adjustment is rapid and accurate, the cutting efficiency is improved, the wire breaking fault caused by too large cutting wire pulling force is avoided, and the product quality is improved. And the cutting machine is suitable for cutting different materials and different sections.

Description

technical field [0001] The invention relates to the technical field of multi-wire cutting machines, in particular to a novel material plate lifting platform structure of the multi-wire cutting machine. Background technique [0002] At present, the widely used equipment for cutting various hard and brittle materials such as magnetic materials, crystals, ceramics, compounds, oxides, sapphire, and single crystal silicon is multi-wire cutting machine. Multi-wire cutting is a high-speed reciprocating motion through metal wires. A new type of cutting method that brings abrasives into the workpiece processing area for grinding and cuts hard and brittle materials into multiple slices at one time. Compared with other technologies, it has the advantages of high efficiency, high productivity, high precision and simple operation. [0003] When the multi-wire cutting machine is working, the cutting line is guided by more than a dozen wire wheels to form a net on the cutting roller assemb...

AI Technical Summary

Problems solved by technology

[0004] The feed of the existing multi-wire cutting machine lifting table is mostly set manually in sections. The feeding speed of the lifting table in each section is constant, and the cutting section of the workpiece is mostly changed. The cutting resistance and cutting resistance of the section are different. The cutting speed is different, which will cause the workpiece to be fed too fast when the cutting speed is reduced when the cross section of the workpiece is large, so that the force on the cutting line will increase. When the cross-section of the workpiece becomes smaller and the cutting speed increases, the feed of the workpiece is relatively slow, which reduces the force on the cutting line and cannot generate enough pressure, resulting in a decrease in cutting efficiency.

And because of the uneven force on the cutting line, the bending degree of the cutting line is inconsistent, resulting in uneven cutting marks on the cutting surface, reducing the cutting quality of the cutting product, and increasing the workload and difficulty of the subsequent process of cutting the product

[0005] Different materials and different cross-sections have different cutting speeds. The manual calculation of the feed speed can only be applied to relatively simple and regular cross-section shapes, but it cannot be calculated for complex and irregular cross-sections. It can only be set according to experience, and the error is large.
