Description
Technical Field
[0001] The utility model belongs to the technical field related to cutting fluid circulation, and particularly relates to a working fluid circulation mechanism for a wire cutting machine tool. Background Art
[0002] Wire-cut cutting machines are widely used in metalworking, demonstrating their unique advantages in machining high-precision, complex workpieces. However, during the wire-cutting process, the cutting fluid, which serves as both a cooling and discharge medium, can contain metal shavings, oil, and other impurities. Direct discharge of this fluid not only wastes resources but also pollutes the environment. Therefore, effectively recycling cutting fluid while maintaining its cleanliness and reducing costs has become a pressing issue.
[0003] While some cutting fluid recycling solutions exist, most rely on simple filtration, making it difficult to completely remove tiny metal chips and floating debris. The filtered cutting fluid often falls short of cleanliness standards, impacting the machining accuracy and service life of wire-cutting machines. Furthermore, the separation and collection of metal chips during the filtration process is often inefficient, increasing maintenance costs.
[0004] To address these issues, this patent proposes a working fluid recycling mechanism for wire-cutting machines. This mechanism not only efficiently removes metal chips, oil, and other impurities from the cutting fluid, but also automatically collects floating debris. Through multi-stage filtration and purification, it ensures the recycling of the cutting fluid, improving resource utilization while reducing environmental pollution. This mechanism, with its sophisticated design and simple operation, significantly reduces the operating costs of wire-cutting machines, improves processing efficiency and workpiece quality, and represents a significant innovation in recycling technology for the metalworking industry.

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] The utility model provides Figures 1-6 The illustrated embodiment shows a working fluid recycling mechanism for a wire cutting machine tool, comprising a wire cutting machine 1. A filter barrel 2 is provided at the front right end of the wire cutting machine 1. An inlet pipe 3 is connected to the upper front end of the filter barrel 2 and is connected to the waste liquid pool inside the wire cutting machine 1 through the inlet pipe 3. An outlet pipe 4 is connected to the upper end of the filter barrel 2 and is connected to the cutting fluid pool inside the wire cutting machine 1 through the outlet pipe 4. A floating object collection pipe 5 is connected to the lower front end of the filter barrel 2 and a metal chip collection pipe 6 is connected to the lower right end of the filter barrel 2. During operation, the cutting machine requires cutting fluid for cooling and providing a discharge medium. After use, the cutting fluid will contain metal chips and other impurities. At this time, the cutting waste fluid can be filtered and purified by the filter barrel 2 and put back into use. The cutting waste fluid in the waste liquid pool can be introduced into the filter barrel 2 through the inlet pipe 3 and the filtered and purified cutting fluid can be re-introduced into the cutting fluid pool through the outlet pipe 4. When the liquid level in the cutting fluid pool is too low, the cutting fluid can be automatically replenished, thereby reducing the use cost of the cutting machine and reducing the pollution of the cutting waste fluid to the environment.
[0030] Preferably, a partition 7 is provided inside the lower end of the filter barrel 2, and the partition 7 is fixedly connected to the inner wall of the filter barrel 2, and an outer filter cartridge 8 with an opening downward is fixedly connected to the outer side of the upper end of the partition 7, an inner filter cartridge 9 with an opening downward is provided inside the outer filter cartridge 8, and the inner filter cartridge 9 is fixedly connected to the upper end of the partition 7, a purification cartridge 10 is provided inside the inner filter cartridge 9, and the purification cartridge 10 is fixedly connected to the center of the upper end of the partition 7, and a float collection ring 13 is provided on the upper side of the outer filter cartridge 8.

Since the plurality of variable diameter filter holes 11 are distributed in four concentric circles, and the radius of the plurality of variable diameter filter holes 11 gradually decreases from the outside to the inside, and are staggered. The position is set, so when the waste liquid passes through the multiple variable diameter filter holes 11 inside the outer filter cartridge 8 and the inner filter cartridge 9, the metal chips will collide with the inner and outer walls of the outer filter cartridge 8 and the inner filter cartridge 9, reducing the movement speed and causing aggregation, so that the aggregated metal chips and larger metal chips cannot pass through the variable diameter filter holes 11 and precipitate. The precipitated metal chips are introduced into the lower end of the partition 7 through the lower end openings of the outer filter cartridge 8 and the inner filter cartridge 9 and the multiple separation through holes 12, thereby filtering and separating the metal chips in the waste liquid, and the metal chips introduced into the lower end of the partition 7 can be prevented from backflow by two anti-reverse baffles 18, avoiding the metal chips from being sucked into the outer filter cartridge 8 and the inner filter cartridge 9 again.

[0034] Preferably, a collecting groove 19 is provided inside the upper end of the floating object collecting ring 13, and the front and rear ends and the left and right sides of the lower end of the collecting groove 19 are connected with inner telescopic tubes 20, and the four inner telescopic tubes 20 are downwardly penetrated into the lower end of the floating object collecting ring 13, and the outer ends of the four inner telescopic tubes 20 are sleeved with outer telescopic tubes 21 and slidably connected with the outer telescopic tubes 21. The lower ends of the four outer telescopic tubes 21 are downwardly penetrated into the lower end of the partition 7, and the lower ends of the four outer telescopic tubes 21 are fixedly connected with a gathering tube 22, and the gathering tube 22 is located on the lower side of the partition 7 and is connected with the floating object collecting tube 5.

In the process of removing floating objects, floating objects are The collecting ring 13 can float on the upper end of the waste liquid through the air bag 23 provided inside the lower end, and the floating position can be limited by the inner telescopic tube 20 and the outer telescopic tube 21 provided at the lower end. Since the height of the outer wall of the upper end of the collecting tank 19 away from the outer filter cartridge 8 is lower than the height of the outer wall of the upper end of the collecting tank 19 close to the outer filter cartridge 8, and the outer wall of the upper end of the collecting tank 19 away from the outer filter cartridge 8 is just flush with the liquid surface of the waste liquid under the buoyancy of the air bag 23, the floating objects at the upper end of the waste liquid can enter the interior of the collecting tank 19 through the outer wall of the upper end of the collecting tank 19 away from the outer filter cartridge 8, and can be introduced into the interior of the gathering tube 22 through the four inner telescopic tubes 20 and the four outer telescopic tubes 21, and the gathering tube 22 is connected to the floating object collecting tube 5, thereby removing the floating objects at the upper end of the waste liquid and discharging and processing them.
