Description

Technical Field

[0001] The invention relates to a wire cutting device, in particular to a medium-speed wire cutting device for mold processing. Background Art

[0002] Medium-speed wire EDM uses multiple cuts to reduce material deformation and errors caused by molybdenum wire loss, resulting in relatively improved processing quality, somewhere between high-speed and low-speed wire EDM machines. Medium-speed, slow-speed, and fast-speed wire EDM all refer to wire EDM machines. They are primarily used for machining complex and fine workpieces, such as mold punches and dies. Developed from EDM perforation and forming processes, they have not only expanded EDM applications but have also replaced these processes in some areas.

[0003] When processing molds, the guide device of the wire cutting device in the existing technology will be worn after long-term use, causing the electrode wire to deviate or vibrate, and even cause the electrode wire to break. The wear is usually gradual and difficult to observe directly with the naked eye. The wire guide device is often not repaired until defects appear in the mold product, which has a lag and affects the overall product quality. Therefore, the guide structure needs to be replaced, and the difficulty in replacing the guide structure increases maintenance time, which is very unfavorable to the processing efficiency of the mold; and metal scraps are generated during cutting, and no recycling mechanism is set, so the metal scraps after cutting cannot be recycled in time.

[0052] When the guide cylinder 303 is seriously worn, it needs to be replaced. During replacement, the U-shaped slider 3012 is toggled to release the limit of the turning handle 3011, that is, the turning handle 3011 can drive the adjusting shaft 301 to rotate ninety degrees (the left adjusting shaft 301 rotates counterclockwise, and the right adjusting shaft 301 rotates clockwise), so that the next guide cylinder 303 is rotated into the vertical cavity, and then the U-shaped slider 3012 is reset to limit the turning handle 3011 to prevent it from being loose, so that the new guide cylinder 303 can be used, thereby realizing the effect of online replacement of the guide cylinder 303 of the wire cutting device;
