Description

Technical Field

[0001] This invention relates to the field of abrasive wheel cutting technology, specifically to a cooling device and method for ultra-high-speed abrasive wheel dicing blades. Background Technology

[0002] During operation, the dicing blades of the ultra-high-speed grinding wheel generate a large amount of heat when dicing the workpiece, causing the temperature of the blade and the workpiece to rise rapidly. Excessive temperature will seriously affect the dicing quality and greatly shorten the service life of the blade. In order to reduce the temperature of the blade and the workpiece, cooling medium needs to be sprayed onto the blade and the workpiece during the dicing process. At the same time, the dicing machine generates waste material during operation. The presence of waste material will adversely affect the dicing quality of the workpiece, so it is necessary to wash the waste material during the operation of the dicing machine.

[0003] For example, in publication number CN110539023A, "A rinsing and cooling device for a dicing cutter and a dicing machine," a U-shaped pipe is used to introduce cooling medium to both sides of the blade along its axial direction for cooling, and simultaneously to introduce cooling medium radially for cooling and rinsing; this is equivalent to spraying cooling medium from three directions at the same time. However, only one end of the U-shaped pipe is fixed to the rotating seat, while the other end is suspended. When high-pressure coolant is introduced into the U-shaped pipe, it is prone to shaking, which may cause contact with the dicing cutter, resulting in instrument damage and production accidents.

[0004] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] This invention provides a cooling device and method for ultra-high-speed grinding wheel dicing cutters, such as... Figure 1-3 As shown, the device includes a cover 1, which is mounted on the outside of the blade. Spray nozzle seats 2 are located on both sides of the cover 1. Each spray nozzle seat 2 has a coolant inlet 3, positioned on the outside of the spray nozzle seat 2. Two sets of parallel spray nozzles 4 are connected to the lower end face of the spray nozzle seat 2. The two ends of each spray nozzle 4 are fixed to the lower end face of the spray nozzle seat 2. The two sets of spray nozzles 4 are positioned on the front and rear sides of the blade and are parallel to the blade surface. The fixed ends of the spray nozzles 4 reduce vibration during operation. Coolant inlets 3 are located on both sides of the spray nozzle seat 2. When one side's coolant inlet 3 is receiving coolant, the other side's coolant inlet 3 is closed.

[0024] Reference Appendix Figure 1-3 The nozzle 4 is divided into a vertical section 41 and a horizontal section 42, which are connected by an arc-shaped transition. A nozzle hole is located in the middle of the horizontal section 42. The nozzle hole pattern is shown in the attached diagram. Figure 3 The nozzles cool and rinse both sides of the blade, which helps to cool the blade and rinse away debris. It should be noted that the nozzles of both sets of nozzles 4 are opened on the side facing the blade.

[0025] Reference Appendix Figure 2 Two connecting rods 5 are provided between the two sets of nozzles 4. The two connecting rods 5 are respectively located on the left and right sides of the blade and perpendicular to the blade surface. The connecting rods 5 and the two sets of nozzles 5 are integrally formed, which further improves the stability of the nozzles 4.

[0026] Reference Appendix Figure 1-2 The lower end face of the nozzle seat 2 is provided with a connecting seat 6. The connecting seat 6 is located in the middle of the connection position between the two sets of nozzles 4 and the nozzle seat 2. The connecting seat 6 is connected to the main cooling pipe 7. The end of the main cooling pipe 7 near the blade is provided with a nozzle 8. The nozzle 8 is connected to the main cooling pipe 7 at an angle of 150 degrees. The nozzle 8 is directly aligned with the lower edge of the blade and plays the main cooling role.

[0027] Reference Appendix Figure 1-2 The connecting rod 5 has an oblique through hole, through which the main cooling pipe 7 passes. The connecting rod 5 is fixedly connected to the main cooling pipe 7, so that the main cooling pipe 7 and the spray pipe 4 are synchronously fixed in position.

[0028] Reference Appendix Figure 1-2 The cover 1 has cooling vents 9 on both sides and a mesh opening 10 on the inner side. The cooling vents 9 and the mesh opening 10 are connected and are at the same level as the upper part of the blade. A glass baffle is fixed to the cover 1 on the outer side of the mesh opening 10. The glass baffle covers the upper part of the blade. The glass baffle is omitted in the attached figure. The cooling vents can remove some heat when they blow over the blade surface, and at the same time reduce the overall temperature inside the working chamber.

[0029] Reference Appendix Figure 1-2 A fixing plate 11 is provided on the outer side of the nozzle seat 2. A fixing hole 12 is provided near the lower half of the fixing plate 11. The main cooling pipe 7 passes through the fixing hole 12 and is fixedly connected to the fixing plate 11.
