Description
Technical Field
[0001] This utility model relates to the technical field of multi-wire cutting equipment, specifically to a cutting fluid supply system for a swing-type multi-wire cutting machine. Background Technology
[0002] Diamond wire cutting machines use diamond particles bonded to cutting wires to create diamond wires. In their wire feeding system, the diamond wires are wound onto grooved wheels according to the cutting process requirements, forming a parallel cutting wire mesh. The grooved wheels drive the cutting wires in a reciprocating motion to cut the workpiece. Table-mounted oscillating multi-wire cutting machines use an oscillating body on the worktable that rotates around an oscillating axis, causing the workpiece to oscillate left and right, bringing it into contact with the cutting wire mesh. Simultaneously, the worktable is driven downwards by a lifting mechanism to feed the workpiece. During operation, table-mounted oscillating multi-wire cutting machines using diamond wires also require the spraying of coolant to cool the cutting wires and remove debris and impurities from the workpiece's kerf.
[0003] In existing technologies, the cutting fluid supply system of diamond wire multi-wire cutting machines uses only one spraying device to simultaneously spray fluid onto the cutting wire and the workpiece. When the coolant spray volume is small, the cooling effect on the diamond cutting wire is poor, which not only significantly shortens the lifespan of the diamond wire and increases its consumption, but also negatively impacts the flatness, roughness, and parallelism of the workpiece's cut surface. Furthermore, it makes it difficult to remove debris and impurities from the workpiece's kerf in a timely manner. When the coolant spray volume is excessive, the spray pressure can also impact the cutting wire mesh, affecting the workpiece's cutting quality. Therefore, in the operation of a table-mounted diamond wire multi-wire cutting machine, the cutting fluid supply system is crucial for ensuring product quality and reducing production costs. Thus, it is necessary to optimize the design of the cutting fluid supply system's structure and its integration with the multi-wire cutting machine. Utility Model Content

[0045] Multi-wire cutting machines are slicing equipment that uses the high-speed reciprocating motion of cutting wires to grind the material being cut with abrasive, simultaneously cutting the workpiece into hundreds or even thousands of thin slices. Multi-wire cutting equipment using diamond wire as the cutting wire is called diamond wire multi-wire cutting equipment. Diamond particles are fixed onto the cutting wire to form diamond wire. In its wire feeding system, the diamond wire is wound around a grooved wheel according to the cutting process requirements to form a parallel cutting wire mesh. The grooved wheel drives the diamond wire to reciprocate to cut the workpiece. With the increasing trend of diverse materials and sizes of workpieces being cut, the structure of multi-wire cutting machines is constantly being innovated, and table-mounted oscillating multi-wire cutting machines suitable for large workpieces have emerged. However, when the cutting wire of the table-mounted multi-wire cutting machine is diamond wire, it is necessary to use cutting fluid (abrasive fluid) to cool the cutting wire. If the cutting fluid is not supplied sufficiently, the cooling effect will be poor, the service life of the diamond wire will be greatly shortened, the consumption of diamond wire will increase, and it will also have an adverse effect on the flatness, roughness and parallelism of the workpiece cut surface. In addition, in order to ensure that the debris and impurities in the workpiece kerf can be carried away by the cutting fluid in time, it is also necessary to ensure that the cutting fluid is supplied sufficiently.
