Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a cutting device for a slow-moving wire cutting machine. Background Art

[0002] Slow wire cutting, also known as low-speed wire cutting, is a CNC machining machine that uses a continuously moving thin metal wire as an electrode to perform pulse spark discharge on the workpiece, generating a high temperature of over 6000 degrees, etching the metal and cutting it into the workpiece.

[0003] In the existing technology, in order to ensure smooth cutting, coolant is often sprayed on the cutting point of the workpiece when necessary to ensure that the equipment maintains normal operating temperature to prevent the metal in the cutting area from overheating, thereby causing problems such as distortion, deformation, and cracking. The coolant can also reduce electrode wear, prevent electron evaporation and melting, and improve cutting efficiency.

[0004] However, the cooling structure of such cutting devices in the prior art generally has an upper limit for spraying coolant. Therefore, when cutting thicker plates, the lower end of the material cannot be cooled quickly and in a timely manner, and overheating is still prone to occur. Therefore, an improved cutting device of a slow-feed wire cutting machine is needed to address this problem. Utility Model Content

The control mechanism can control the flow direction of the coolant as needed.

[0025] The flow channel 11 is T-shaped. The T-shaped flow channel 11 is matched with the rotatable ball valve core 10, so that the control mechanism can be understood as a three-way ball valve. According to the different rotation directions of the T-shaped flow channel 11, such as Figure 4 、 Figure 5 、 Figure 6 As shown, Figure 4 Make the coolant flow into the upper water supply pipe 6 and the lower water supply pipe 7 respectively: Figure 5 The coolant flows into the lower water supply pipe 7 alone, and Figure 6 The coolant flows into the upper water supply pipe 6 separately, which can provide a variety of coolant spraying methods for the device; so that the device can adapt to the processing cooling requirements of different parts;
