Description

Technical Field

[0001] This utility model relates to the field of nickel-titanium alloy processing technology, and in particular to a chip collection box for nickel-titanium alloy processing. Background Technology

[0002] Nickel-titanium alloys are widely used in aerospace, medical devices, and precision instruments due to their unique superelasticity, shape memory effect, and biocompatibility. During the machining of nickel-titanium alloys, processes such as cutting, grinding, and drilling generate a large amount of fine debris, along with liquid media such as cutting fluid and lubricating oil. If this solid-liquid mixture containing nickel-titanium alloy debris is not effectively treated, it will not only lead to resource waste but may also cause equipment wear due to debris entering the machining system. Direct discharge of waste liquid will also cause environmental pollution. Therefore, efficient solid-liquid separation of nickel-titanium alloy debris is crucial.

[0003] Currently, most existing metal debris collection devices employ simple filter screen filtration or centrifugal separation methods. Filter screen filtration devices typically rely solely on gravity to allow liquid to pass through the filter screen. Nickel-titanium alloy debris, being lightweight and prone to agglomeration, easily clogs the filter screen pores, resulting in low filtration efficiency. Furthermore, due to the lack of effective flow guiding and blocking structures, the debris remains on the filter screen surface for a short time, leading to insufficient solid-liquid separation and often resulting in residual liquid within the debris. Therefore, this invention proposes a novel solution. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a chip collection box for nickel-titanium alloy processing, which can solve the problem that due to the lack of an effective flow guiding and blocking structure, the chip stays on the filter screen surface for a short time, the solid-liquid separation is insufficient, and the residual liquid in the chip often occurs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chip collection box for nickel-titanium alloy processing, comprising a chip collection box and a control box;

[0006] The debris filter assembly is installed on the debris collection box. The debris filter assembly includes a filter screen, which is inclinedly installed inside the debris collection box and slidably connected to the debris collection box. Two fixed brackets are fixedly connected to the left side of the debris collection box, and a drive motor is fixedly connected to the surface of the front fixed bracket.

[0007] The output end of the drive motor is fixedly connected to a rotating shaft, and two cams are fixedly connected to the surface of the rotating shaft. A movable frame is slidably connected inside the debris collection box, and multiple push blocks with right-angled triangular cross-sections are fixedly connected to the inner side of the movable frame.

[0008] The left side of the movable frame is fixedly connected to two connecting frames, and two cams are slidably connected to their respective connecting frames.

A connecting plate is fixedly connected to the lower end of the movable frame, and guide rods are fixedly connected to the surfaces of the two connecting plates. The guide rods are slidably connected to the fixing plate.

[0010] A spring is fitted onto the surface of the guide rod. The two ends of the spring are fixedly connected to the connecting plate and the fixing plate, respectively. There are two sets of both the guide rod and the spring, which are symmetrically arranged on the connecting plate.

[0011] Preferably, a feed hopper is fixedly connected to the upper end of the debris collection box, and a partition is fixedly connected inside the debris collection box;

[0012] The inside of the debris collection box is slidably connected to a first cutting fluid collection box and a second cutting fluid collection box. The front sides of the first cutting fluid collection box and the second cutting fluid collection box are respectively fixedly connected to two first drain pipes and two second drain pipes.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a chip collection box for nickel-titanium alloy processing, including a chip collection box 1 and a control box 2, a chip filtering assembly, the chip filtering assembly being disposed on the chip collection box 1, the chip filtering assembly including a filter screen 7, the filter screen 7 being obliquely disposed inside the chip collection box 1 and slidably connected to the chip collection box 1, two fixed supports 8 being fixedly connected to the left side of the chip collection box 1, a drive motor 9 being fixedly connected to the surface of the front fixed support 8, a rotating shaft 10 being fixedly connected to the output end of the drive motor 9, two cams 11 being fixedly connected to the surface of the rotating shaft 10, a movable frame 13 being slidably connected inside the chip collection box 1, multiple push blocks 14 with right-angled triangular cross sections being fixedly connected to the inner side of the movable frame 13, two connecting frames 16 being fixedly connected to the left side of the movable frame 13, and the two cams 11 being slidably connected to the corresponding connecting frames 16 respectively.

[0031] The debris filter assembly also includes a fixed plate 12, which is fixed to the opposite sides of two fixed supports 8. A connecting plate 15 is fixedly connected to the lower end of the movable frame 13. Guide rods 17 are fixedly connected to the surfaces of the two connecting plates 15. The guide rods 17 are slidably connected to the fixed plates 12. Springs 18 are sleeved on the surface of the guide rods 17. The two ends of the springs 18 are fixedly connected to the connecting plates 15 and the fixed plates 12, respectively. There are two sets of guide rods 17 and springs 18, which are symmetrically arranged on the connecting plates 15.

[0032] The upper end of the chip collection box 1 is fixedly connected to the feed hopper 5. The inside of the chip collection box 1 is fixedly connected to the partition plate 6. The inside of the chip collection box 1 is slidably connected to the first cutting fluid collection box 20 and the second cutting fluid collection box 22. The front sides of the first cutting fluid collection box 20 and the second cutting fluid collection box 22 are respectively fixedly connected to two first drain pipes 21 and two second drain pipes 23.

[0033] A first guide frame 19 is fixedly connected to the opposite side of the debris collection box 1 and the partition 6, and a second guide frame 24 and a third guide frame 26 are fixedly connected to the right side of the partition 6.

[0034] The inside of the debris collection box 1 is equipped with an inclined conveyor belt 25.

[0035] The lower end of the debris collection box 1 is equipped with four casters 3.

[0036] A pusher 4 is fixedly connected to the right side of the debris collection box 1.

[0037] When using the device, a solid-liquid mixture containing nickel-titanium alloy chips (such as a mixture of cutting fluid, lubricating oil and chips) is poured into the feed hopper 5 at the top of the chip collection box 1, and the feed hopper 5 guides the mixture into the box.

[0038] The mixture falls onto the surface of the inclined filter screen 7. Under the action of gravity, the liquid flows downward through the pores of the filter screen 7, while the nickel-titanium alloy debris is intercepted on the surface of the filter screen, achieving preliminary solid-liquid separation. The inclined setting of the filter screen 7 allows the liquid to flow down faster, while providing an inclined surface for guiding and blocking the debris.

[0039] The drive motor 9 on the left side of the debris collection box 1 starts, driving the rotating shaft 10 to rotate. The two cams 11 on the surface of the rotating shaft 10 rotate accordingly. When the cams 11 rotate, they contact the connecting frame 16 on the left side of the movable frame 13 and push it to move. When the protruding part of the cam 11 contacts the connecting frame 16, it pushes the movable frame 13 to slide to the right. When the protruding part of the cam 11 moves away from the connecting frame 16, the movable frame 13 slides to the left to reset under the elastic force of the spring 18. This cycle repeats, causing the movable frame 13 to slide back and forth horizontally inside the debris collection box 1.

[0040] Multiple push blocks 14 with right-angled triangular cross-sections are fixedly connected to the inner side of the movable frame 13. When the movable frame 13 slides back and forth, the push blocks 14 move back and forth synchronously on the surface of the filter screen 7. When the right-angled triangular push block 14 slides to the left, its hypotenuse faces the debris, which can block the debris on the surface of the filter screen and make the debris stay on the surface of the filter screen for a longer time, which is conducive to the full filtration of liquid. When it slides to the right, the right-angled side faces the debris and pushes the debris. Through the reciprocating motion of the push block 14, the residence time of the debris on the surface of the filter screen 7 is extended, the fullness of solid-liquid separation is improved, and the debris can also be prevented from clogging the filter screen pores.

[0041] The filtered cutting fluid flows downward through the filter screen 7 and is guided by the first guide frame 19 fixed on the opposite side of the chip collection box 1 and the partition 6, and is guided to the first cutting fluid collection box 20 located on the left side of the partition 6; the first drain pipe 21 on the front side of the first cutting fluid collection box 20 is connected to the water pump of the nickel-titanium alloy processing equipment, which can transport the filtered cutting fluid back to the cutting fluid tank inside the equipment to realize the recycling of cutting fluid.

[0042] Some of the incompletely filtered cutting fluid may carry fine debris down and be guided by the second guide frame 24 on the right side of the partition 6 to the inclined conveyor belt 25. The operation of the conveyor belt 25 transports the debris to the outside of the debris collection box 1 for collection, while the cutting fluid flows down from the conveyor belt 25 and is guided by the third guide frame 26 to the second cutting fluid collection box 22 located on the right side of the partition 6. The second drain pipe 23 on the front side of the second cutting fluid collection box 22 can discharge the cutting fluid in the box for further processing or discharge.

[0043] The first cutting fluid collection tank 20 and the second cutting fluid collection tank 22 can be slid out from inside the debris collection tank 1, which facilitates the cleaning of cutting fluid and residual debris in the tanks and keeps the collection tanks clean and in normal working order.

[0044] The filter screen 7 is slidably connected to the debris collection box 1 and can be removed from the box for easy cleaning or replacement of the clogged filter screen, ensuring the filtration effect.

[0045] The chip collection box 1 is equipped with four casters 3 at the bottom and a pusher 4 is fixedly connected to the right side, which makes it easy for operators to push the collection box to move, so that it can be flexibly arranged on the processing site and conveniently receive chips and cutting fluid generated by different processing equipment.

[0046] The control box 2 is equipped with a control system, which is used to control the start and stop of the drive motor 9, the running speed of the conveyor belt 25, etc., to realize the automated operation of the entire collection box and improve work efficiency and convenience.

[0047] Furthermore, the reciprocating motion of the inclined filter screen 7 and the right-angled triangular pusher block 14 works synergistically to significantly improve the solid-liquid separation efficiency. The inclined filter screen design increases the liquid flow rate, while the blocking effect of the pusher block 14 prolongs the residence time of debris on the filter screen surface, ensuring that the liquid is fully filtered. This improves the solid-liquid separation rate, effectively reduces cutting fluid waste, and achieves resource recycling.
