Description

Technical Field

[0001] This utility model relates to the field of metal cutting technology, specifically to a metal cutting equipment with a spray cooling device. Background Technology

[0002] Metal cutting is a material removal and forming method in metal forming processes, and it still accounts for a large proportion in modern machinery manufacturing. The metal cutting process is an interaction between the workpiece and the cutting tool. The cutting tool removes excess metal from the workpiece and, under the premise of controlling productivity and cost, enables the workpiece to obtain geometric accuracy, dimensional accuracy and surface quality that meet the design and process requirements. In the metal cutting process, a spray cooling device is required to cool the cutting tool.

[0003] According to a published application for a metal cutting spray cooling device (publication number: CN222493355U), the device includes a support rod, a movable lifting assembly, and a multi-directional spray assembly. A motor mounting frame is fixed above the support rod, and a movable lifting assembly is provided below the motor mounting frame. A lifting plate is connected below the movable lifting assembly, and a multi-directional spray assembly is installed below the lifting plate.

[0004] However, in actual use, the above-mentioned spray cooling device is located on one side of the cutting position, and the spray can only cover part of the tool and workpiece. The single-sided spray is easily blocked by the chips, making it difficult for the cutting fluid to fully cover the friction and heat generation area, which leads to increased thermal stress and tool wear. In view of this, we propose a metal cutting equipment with a spray cooling device. Utility Model Content

[0005] The purpose of this invention is to provide a metal cutting processing equipment with a spray cooling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal cutting processing device with a spray cooling device, comprising a processing device, a movable block disposed on the side wall of the processing device, and a cooling assembly disposed at the bottom of the movable block, the cooling assembly comprising: A slide rail is slidably connected to a rotating ring, and a transmission gear is fixedly connected to the top end face of the rotating ring; Motor 2, the output shaft of motor 2 is fixedly connected to a drive gear, the bottom end face of the drive gear is fixedly connected to a toggle rod, the side wall of the moving block is rotatably connected to a rotating rod, and the bottom end of the rotating rod is fixedly connected to a driven gear; A curved tube is rotatably connected to the bottom end of the curved tube.

[0008] Preferably, the slide rail is fixedly connected to the bottom end face of the moving block, the rotating ring is hollow, and a water inlet pipe is fixedly connected to the side wall of the rotating ring to supply water to the rotating ring and the bend pipe.

[0013] Compared with the prior art, the present invention provides a metal cutting processing equipment with a spray cooling device, which has the following beneficial effects: 1. This metal cutting equipment with a spray cooling device, through its cooling components, features a reciprocating rotating nozzle with continuously intersecting and overlapping spray trajectories.

[0017] like Figures 1-6 As shown, this utility model provides a technical solution: a metal cutting processing equipment with a spray cooling device, including a processing device 1, a moving block 2 is provided on the side wall of the processing device 1, and a cooling component 5 is provided at the bottom of the moving block 2. The cooling component 5 includes a slide rail 501, a rotating ring 502, a transmission gear 503, a motor 504, a driving gear 505, a toggle lever 506, a driven gear 507, a bent pipe 508, a nozzle 509, a spray hole 510, and a spiral tube 511.

[0018] In one embodiment of this utility model, the slide rail 501 is fixedly connected to the bottom end face of the moving block 2, the slide rail 501 is slidably connected to the rotating ring 502, the top end face of the rotating ring 502 is fixedly connected to the transmission gear 503, the rotating ring 502 is hollow, and the side wall of the rotating ring 502 is fixedly connected to the water inlet pipe 6, through which water is supplied to the rotating ring 502 and the bent pipe 508.

[0019] A connecting frame 9 is fixedly connected to the side wall of the movable block 2. The bottom of the connecting frame 9 is fixedly connected to the second motor 504. The output shaft of the second motor 504 is fixedly connected to the drive gear 505. The bottom end face of the drive gear 505 is fixedly connected to the actuating rod 506. A rotating rod is rotatably connected to the side wall of the movable block 2. The bottom end of the rotating rod is fixedly connected to the driven gear 507. The second motor 504 drives the drive gear 505 to rotate in the forward direction. The drive gear 505 meshes with the driven gear 507. The bottom end face of the driven gear 507 is fixedly connected to the actuating rod 506. The actuating rod 506 meshes with the transmission gear 503.

[0020] The bent tube 508 is fixedly connected to the bottom end face of the rotating ring 502. The bottom end of the bent tube 508 is rotatably connected to the nozzle 509. The nozzle 509 has a spray hole 510 on its inner bottom surface. The inner wall of the nozzle 509 is fixedly connected to the spiral tube 511. The bent tube 508 is movably connected to the steel ball 7, and the steel ball 7 is movably connected to the nozzle 509.

[0021] A motor 3 is fixedly connected to the top end face of the moving block 2, and a cutter head 4 is fixedly connected to the output end of the motor 3. The axis of the rotating ring 502 coincides with the axis of the cutter head 4.

[0022] Motor 504 drives the drive gear 505 to rotate forward. Through the transmission of the lever 506, it drives the transmission gear 503, the rotating ring 502, and the nozzle 509 to rotate in the opposite direction. Since the ratio of the number of levers 506 to the gears of the transmission gear 503 is 1:2, one rotation of the drive gear 505 drives the rotating ring 502 and the nozzle 509 to rotate half a turn in the opposite direction. The forward rotation of the drive gear 505 drives the driven gear 507 to rotate in the opposite direction. The levers 506 at the bottom of the driven gear 507 and the levers 506 at the bottom of the drive gear 505 are staggered. After the drive gear 505 drives the nozzle 509 to rotate half a turn in the opposite direction, the levers 506 at the bottom of the driven gear 507 drive the rotating ring 502 to rotate half a turn in the forward direction. The spray trajectory continuously intersects and overlaps, which can ensure more uniform spray coverage, avoid spray dead zones, improve spray uniformity, and have a better cooling effect.

[0023] The portion of the nozzle 510 located inside the nozzle 509 is a narrowing section, while the portion located outside the nozzle 509 is a diffusion section. Under high pressure, the liquid enters the narrowing section of the nozzle 510, where the orifice diameter decreases and the flow velocity increases. Then, as the liquid flows into the gradually expanding diffusion section, the flow velocity suddenly decreases, causing turbulence and eddies. The flow stream is disturbed and becomes unstable. This disturbance makes it difficult for the surface tension of the liquid to maintain a continuous state, causing the liquid to split into a large number of small droplets, forming atomized droplets. Small droplets are easier to distribute evenly on the workpiece surface or in the air than large droplets, resulting in a larger coverage area and more uniform spraying. In cooling or lubrication scenarios, this allows the liquid to fully contact the tool and workpiece surfaces. Small droplets have a larger specific surface area than large droplets, resulting in more contact with the air and workpiece surfaces per unit volume, improving heat transfer efficiency, and enabling faster cooling of the tool or workpiece, thus preventing localized overheating.

[0024] Liquid enters the spiral tube 511 from the side wall of the nozzle 509. The channel of the spiral tube 511 is arranged at an inclined tangential direction. The liquid is forced to flow along a curved path inside the tube. When it flows out, it has a thrust in the direction of rotation, which makes the nozzle 509 rotate. The rotational motion allows the sprayed liquid flow to mix fully with the air, increases shear disturbance, and makes it easier for small droplets to form uniform atomization, thereby improving coverage efficiency, cooling and lubrication effects.

[0025] In addition, the inner wall of the nozzle 509 is provided with an umbrella-shaped water outlet 8. The umbrella-shaped water outlet 8 inside the nozzle 509 can form a ring-shaped, dispersed liquid flow protection barrier to block or deflect the chips, prevent the chips from splashing in a straight line, reduce dust and debris splashing in the workshop, protect operators and surrounding equipment, and improve safety.

[0026] In this invention, during use, the drive gear 505 rotates one revolution, causing the rotating ring 502 and the nozzle 509 to rotate half a revolution in the opposite direction. The forward rotation of the drive gear 505 causes the driven gear 507 to rotate in the opposite direction. The actuating rod 506 at the bottom of the driven gear 507 is staggered with the actuating rod 506 at the bottom of the drive gear 505. After the drive gear 505 drives the nozzle 509 to rotate half a revolution in the opposite direction, the actuating rod 506 at the bottom of the driven gear 507 drives the rotating ring 502 to rotate half a revolution in the forward direction. The spray trajectory continuously intersects and overlaps, which can ensure more uniform spray coverage, avoid spray dead zones, improve spray uniformity, and achieve better cooling effect. The liquid sprayed from the nozzle 510 forms atomized droplets, which can allow the liquid to fully contact the surface of the tool and the workpiece, improve heat transfer efficiency, and cool the tool or workpiece faster, preventing local overheating.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
