Description

Technical Field

[0001] The invention relates to the technical field of wire cutting machine tools, in particular to a wire cutting machine body finishing fixture. Background Art

[0002] With the expansion of industrial production scale and the development of manufacturing technology, wire cutting technology, as a special processing technology, has been widely used in mechanical processing production due to its high processing accuracy, high production efficiency, low power consumption, and low manufacturing cost. Especially in the mold processing industry, EDM wire cutting technology is widely used in cold stamping die and extrusion die processing, which has changed the past processing mode of separate molds and curve grinding, shortened the manufacturing cycle, reduced manufacturing costs, and has high matching accuracy. The EDM wire cutting machine belongs to the category of electrical processing. When studying the phenomenon and cause of switch contacts being damaged by spark discharge corrosion, it was found that the instantaneous high temperature of the electric spark can cause local metal to melt, oxidize and be corroded, thus creating and inventing the EDM method. The principle is that free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. At this stage, a current is formed between the two plates. This causes countless collisions between particles, forming a plasma zone, which quickly rises to a high temperature of 8,000 to 12,000 degrees, instantly melting some materials on the surfaces of the two conductors. Wire cutting machines generally use fixtures to position the workpiece.

[0003] The existing positioning fixture used in general wire cutting machine tools has a relatively simple structure. During positioning, multiple adjustments are required to accurately position the workpiece, which has low efficiency. Therefore, a wire cutting machine body finishing fixture is proposed.
