Large alloy steel part cutting method through diamond wire saw

Abstract

The invention discloses a large alloy steel part cutting method through a diamond wire saw. Firstly, hanging a large alloy steel part to be cut to a cutting working platform, determining a cutting position of the large alloy steel and making a marker line, then mounting a diamond wire saw, putting the diamond wire saw to the position of the marker line, and adjusting the cutting device to enable the diamond wire saw to be perpendicular to the marker line; secondly, cooling the large alloy steel part with coolant, performing grinding and cutting through closed-loop high-speed rotating of the diamond wire saw; finally, cutting the large alloy steel part to finish cutting. According to the large alloy steel part cutting method through the diamond wire saw, the selected diamond saw is flexible and belongs to high-speed cold machining, not only machining damage and deformation of the large alloy steel part to be cut can be avoided, but also the cutting efficiency and accuracy of the large alloy steel part can be improved, and labor intensity can be effectively reduced.

Description

(1) Technical field: [0001] The invention relates to a metal steel casting cutting technology, in particular to a method for cutting large alloy steel pieces with a diamond wire saw, so as to realize the non-damaging cutting of large alloy steel pieces. (two) background technology: [0002] At present, the cutting and processing methods of large alloy steel parts and castings at home and abroad mainly use flame cutting. This method uses oxygen as fuel, and uses the burning gas to perform high-temperature cutting on alloy steel parts under high pressure. The processing equipment is simple and easy to operate. , The cutting cost is low, and it is widely used in the fields of metallurgy, casting, and steel processing. It is currently the most commonly used method for cutting large metal bodies. [0003] There are following problems in described flame cutting mode: [0004] 1. The cutting seam area is relatively large, between 20mm and 30mm, and the consumables are relatively l...

AI Technical Summary

Problems solved by technology

[0004] 1. The cutting seam area is relatively large, between 20mm and 30mm, and the consumables are relatively large

[0005] 2. After cutting, a large number of residues appear on the cutting surface, which increases the difficulty of subsequent processing

[0006] 3. The working environment has high temperature and high labor intensity, especially for workpieces with high quality requirements, which need to be cut at high temperature (cutting at room temperature is prone to cracks)

[0007] 4. The cutting area is limited, and the cutting radius by flame method generally does not exceed 500mm

[0008] 5. The cutting efficiency is low and the operation is complicated. The manual operation adopted by the flame method is difficult to execute and the efficiency is low.

[0009] 6. The cutting deformation is large, the cutting precision is not high, and the cutting speed is low, the cutting warm-up time and piercing time are long, it is difficult to adapt to the needs of fully automatic operation

[0010] 7. For stainless steel and non-ferrous metals, it is not possible to use the flame method for cutting, because the surface of stainless steel will produce a high-density oxide layer after heating, which prevents the heat from being transferred downwards, thus affecting further cutting

[0014] At present, there is no report on the cutting application of diamond wire saws on large metal bodies at home and abroad, but diamond wire saws have relatively mature foundations in carcass design, diamond performance, preparation, cutting operations, and cutting equipment. Therefore, according to large metal bodies It is feasible to use the existing resources and experience to cut diamond wire saws on large metal bodies.
