Description

Technical Field

[0001] This invention relates to the field of cutting waste collection, specifically to a metal waste collection device for metal cutting. Background Technology

[0002] In the field of metal cutting, a large amount of metal waste is generated during the cutting process. To ensure machining accuracy and tool life, cutting fluid is usually sprayed for cooling and lubrication, resulting in a mixture of waste and cutting fluid. This poses multiple challenges to waste collection, cutting fluid recovery, and production environment maintenance. An efficient waste collection device not only needs to achieve rapid waste collection but also needs to address key requirements such as effective separation of waste and cutting fluid, prevention of secondary pollution, and reduction of labor costs. It is one of the core pieces of equipment for ensuring production continuity and environmental compliance. Existing metal cutting waste collection technologies have several shortcomings that urgently need to be addressed: Firstly, the mixture of waste and cutting fluid accumulates, resulting in extremely low efficiency for manual transfer: In traditional metal cutting, the mixture of waste and cutting fluid accumulates directly on the surface of the machining platform, lacking automated collection channels. Manual collection using tools such as shovels and pushers is required to collect the mixture and transfer it to a dedicated solid-liquid separation station. This operating mode is not only labor-intensive and consumes a large amount of manpower, but also prone to scattering of waste chips and dripping of cutting fluid during the transfer process, causing pollution to the workshop floor. At the same time, the frequency of manual transfer is limited by the production rhythm, and the long-term accumulation of mixed fluids will reduce the operating space of the processing platform and even affect the normal operation of the cutting equipment. Frequent manual intervention directly causes production interruptions, which seriously restricts the improvement of processing efficiency. In addition, during manual transfer, operators need to come into direct contact with oily waste chips and cutting fluid, posing safety hazards such as skin irritation and slipping and falling, which does not meet the requirements of modern industrial safety management. Secondly, the sieving-type solid-liquid separation has a fatal shortcoming: waste chip discharge is difficult. Although some existing collection devices use a sieving structure to achieve preliminary solid-liquid separation, the sieve plate is mostly designed as a fixed type. The separated waste chips continue to accumulate on the surface of the sieve plate, lacking an efficient chip removal mechanism. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a metal waste collection device for metal cutting, which solves the shortcomings of the prior art.

[0004] The objective of this invention is achieved through the following technical solution: a metal waste collection device for metal cutting, comprising an inclined collection platform and a waste processing box. The top surface of the inclined collection platform is an inclined slope. The waste processing box is installed at the bottom of the inclined collection platform. The waste processing box has a processing chamber extending through it along its height. The top surface of the inclined collection platform has several chip discharge ports, which are connected to the processing chamber of the waste processing box. A screening and draining plate is installed inside the waste processing box. A tooling platform is fixed to the top surface of the inclined collection platform, and the top surface of the tooling platform is horizontally positioned.

[0005] Furthermore, the left and right screening plates, which are arranged opposite each other, are in horizontal contact to form the screening and drainage plates. The left and right screening plates are rotatably connected to a first sliding plate at the end of the left screening plate away from the right screening plate, and the right screening plate is rotatably connected to a second sliding plate at the end of the right screening plate away from the left screening plate. Both the first and second sliding plates slide through the waste disposal box, so that the left and right screening plates can deflect downwards to discharge the waste on them.

[0006] Furthermore, the top of the first slide plate is connected to a first L-shaped rod, and the bottom of the second slide plate is connected to a second L-shaped rod. The first L-shaped rod and the second L-shaped rod are staggered vertically. The bottom of the first L-shaped rod is fixed with a first rack, and the top of the second L-shaped rod is fixed with a second rack. A gear is provided between the second rack and the first rack. The gear is rotatably connected to the waste disposal box, and both the first rack and the second rack mesh with the gear.

[0007] Furthermore, a cylinder is installed on the side wall of the waste disposal box, and the telescopic shaft of the cylinder is connected to the first L-shaped rod.

[0008] Furthermore, the left screening plate and the first slide plate are connected by a first hinge, one end of which is connected to the bottom of the left screening plate and the other end of which is connected to the bottom of the first slide plate. The right screening plate and the second slide plate are connected by a second hinge, one end of which is connected to the bottom of the right screening plate and the other end of which is connected to the bottom of the second slide plate.

[0009] Furthermore, a left winding shaft is rotatably connected to the end of the first slide away from the left screening plate. A first pull wire is wound on the left winding shaft, and the first pull wire moves through the first slide and connects to the left screening plate. A first motor is installed on the first slide, and the output shaft of the first motor is driven and connected to the left winding shaft. A right winding shaft is rotatably connected to the end of the second slide away from the right screening plate. A second pull wire is wound on the right winding shaft, and the second pull wire moves through the second slide and connects to the right screening plate. A second motor is installed on the second slide, and the output shaft of the second motor is driven and connected to the right winding shaft.

[0010] Furthermore, the bottom of the waste disposal box is connected to a bottom cover, and the bottom cover is connected to a drain hose. The inner bottom wall of the bottom cover is conical, and its height gradually decreases along the direction close to the drain hose.

[0011] Furthermore, a mounting frame is fixed to the top of the bottom cover, and a closed sealing gasket is fixed to the inner wall of the mounting frame. The closed sealing gasket is in an interference fit with the outer wall of the waste disposal box. Screws are connected to the side wall of the mounting frame, and the screws are threaded onto the waste disposal box. The screws are located below the closed sealing gasket.

[0012] Furthermore, a fence is fixed to the lower end of the inclined collection platform, and a chip removal groove is opened on the inner side of the fence. The chip removal groove and the fence are both V-shaped, and the chip removal groove is connected to the processing chamber.

[0013] The beneficial effects of this invention are: 1. By utilizing the inclined design of the collection platform, combined with the guiding effect of the V-shaped chip removal channel and the fence, the mixture of waste chips and cutting fluid generated during metal cutting automatically flows towards the chip removal port under gravity, directly merging into the processing chamber of the waste chip treatment box. This completely replaces the traditional manual collection and transfer operation mode using shovels and pushers. The horizontally set tooling platform not only ensures the precision requirements of metal cutting processing but also forms a functional zone with the inclined collection channel, preventing waste chips from accumulating and occupying processing space. This design not only completely eliminates the pollution problems of waste chips scattering and cutting fluid dripping during manual transfer but also reduces equipment downtime caused by manual cleaning, significantly improving production continuity. Simultaneously, it avoids direct contact between operators and oily waste chips and cutting fluid, eliminating safety hazards such as skin irritation and slips, meeting modern industrial safety management standards.

[0014] 2. The system employs a screening and drainage plate structure formed by splicing a left and right screening plate, combined with a sliding first and second slide plate, a first pull wire, and a second pull wire design, achieving an integrated function of "screening separation - automatic chip removal." By having the first and second slide plates slide in opposite directions, the left and right screening plates separate, creating the space needed for deflection. Then, the left winding shaft releases the first pull wire, and the right winding shaft releases the second pull wire, causing the left and right screening plates to deflect downwards. The accumulated waste chips quickly fall off and are discharged under gravity, completely solving the fatal flaws of traditional fixed screen plates where waste chips entangle, adhere, and clog the screen holes. This breaks the vicious cycle of "separation-accumulation-clogging-manual cleaning," ensuring the continuity and efficiency of the solid-liquid separation process. Attached Figure Description

Detailed Implementation

[0016] Example 1 like Figures 1 to 4 As shown, a metal waste collection device for metal cutting includes an inclined collection platform 1 and a waste processing box 2. The top surface of the inclined collection platform 1 is an inclined slope. The waste processing box 2 is installed at the bottom of the inclined collection platform 1. The waste processing box 2 has a processing chamber extending through its height. Several chip discharge ports 3 are opened on the top surface of the inclined collection platform 1, and the chip discharge ports 3 are connected to the processing chamber of the waste processing box 2. A screening and drainage plate 4 is installed inside the waste processing box 2. A tooling platform 5 is fixed to the top surface of the inclined collection platform 1. The top surface of the tooling platform 5 is horizontally set. The inclined collection platform 1 is installed within the cutting range of the metal cutting machine. A tooling mechanism is installed on the tooling platform 5. The tooling mechanism is selected according to the shape of the metal parts. For shaft parts, a three-jaw chuck is used, and for other parts, a tooling mechanism is used. Pneumatic grippers are used for tooling fixation. During cutting, the cutting fluid carries metal chips onto the inclined collection platform 1. Based on the flow characteristics of the liquid, the cutting fluid flows from high to low on the inclined collection platform 1. As the cutting fluid flows, it carries the metal chips, causing them to fall into the chip treatment box 2 through the chip discharge port 3. Solid-liquid separation is completed by the screening and drainage plate 4. The separated cutting fluid can be reused after treatment, with a high reuse rate, which reduces costs. The metal chips remain on the screening and drainage plate 4 and are collected uniformly for subsequent use. This completely replaces the traditional manual operation mode of collecting and transporting chips with shovels and push plates, avoids the accumulation of chips occupying processing space, and reduces equipment downtime caused by manual cleaning, significantly improving production continuity.

[0017] Furthermore, such as Figure 1 and Figure 2As shown, a fence 27 is fixed at the lower end of the inclined collection platform 1. A chip discharge trough 28 is provided on the inner side of the fence 27. The shape of the chip discharge trough 28 and the fence 27 are both V-shaped. The chip discharge trough 28 is connected to the processing chamber. Cutting fluid and waste chips that do not flow into the chip discharge port move to the lowest point of the inclined collection platform 1. The fence 27 prevents the cutting fluid and waste chips from leaving the inclined collection platform 1. The fence 27 concentrates the metal waste chips and cutting fluid and discharges them into the waste chip treatment box 2 through the chip discharge trough 28. This allows a large amount of waste chips generated during cutting to enter the waste chip treatment box 2, eliminating the need for waste chip cleaning after each cutting operation and extending the cleaning cycle of the inclined collection platform 1.

[0018] Example 2 Based on Example 1, such as Figure 1 As shown, the bottom of the waste disposal box 2 is connected to a bottom cover 22, and the bottom cover 22 is connected to a drain hose 23. The inner bottom wall of the bottom cover 22 is conical, and its height gradually decreases along the direction close to the drain hose 23. The separated cutting fluid falls into the bottom cover 22 and is discharged to a designated location through the drain hose 23.

[0019] Example 3 Based on Example 2, such as Figures 1 to 4 As shown, a mounting frame 24 is fixed to the top of the bottom cover 22, and a closed sealing gasket 25 is fixed to the inner wall of the mounting frame 24. The closed sealing gasket 25 is in an interference fit with the outer wall of the waste disposal box 2. Screws 26 are connected to the side wall of the mounting frame 24. The screws 26 are threaded onto the waste disposal box 2 and are located below the closed sealing gasket 25. The bottom cover 22 is detachably mounted on the waste disposal box 2 by the screws 26, and the connection between the bottom cover 22 and the waste disposal box 2 is sealed by the closed sealing gasket 25 to prevent liquid leakage. When performing solid-liquid separation, the bottom cover 22 is installed on the waste disposal box 2, and the cutting fluid is discharged into the designated position through the drain hose 23. Metal scraps on the screening drain plate 4 are periodically removed. When removing metal scraps, the bottom cover 22 is removed, allowing the metal scraps to fall from the bottom of the waste disposal box 2.

[0020] Furthermore, the thickness of the closed sealing gasket 25 gradually decreases from top to bottom. The minimum thickness area of ​​the closed sealing gasket 25 is clearance-fitted with the waste disposal box 2, so that the mounting frame 24 can be easily fitted onto the waste disposal box 2. Then, the mounting frame 24 is pressed upward so that the screw 26 corresponds to the threaded hole of the waste disposal box 2. Finally, the screw 26 is screwed on, thereby interfering with the installation of the closed sealing gasket 25 between the mounting frame 24 and the waste disposal box 2, making the installation of the bottom cover 22 simple and quick.

[0021] Example 4 Based on Example 3, such as Figures 1 to 4As shown, the screening and draining plate 4 consists of a left screening plate 6 and a right screening plate 7 arranged opposite each other. The left screening plate 6 and the right screening plate 7 are in horizontal contact to form the screening and draining plate 4. The end of the left screening plate 6 away from the right screening plate 7 is rotatably connected to a first sliding plate 8, and the end of the right screening plate 7 away from the left screening plate 6 is rotatably connected to a second sliding plate 9. Both the first sliding plate 8 and the second sliding plate 9 slide through the waste disposal box 2, allowing the left screening plate 6 and the right screening plate 7 to deflect downwards and discharge the waste on them. When the screening and draining plate 4 is in the screening working state, one end of the left screening plate 6 contacts the first sliding plate 8 and the other end contacts the right screening plate 7, and one end of the right screening plate 7 contacts the second sliding plate 9 and the other end contacts the left screening plate 6, so that... The left screening plate 6 and the right screening plate 7 contact to form a screening and drainage plate 4, enabling the screening and drainage plate 4 to perform solid-liquid separation normally. When it is necessary to discharge metal scraps from the screening and drainage plate 4, the first sliding plate 8 moves the left screening plate 6 away from the right screening plate 7 a certain distance. At the same time, the second sliding plate 9 moves the right screening plate 7 away from the left screening plate 6 a certain distance, separating the left screening plate 6 and the right screening plate 7 to create the space required for downward deflection. Then, the left screening plate 6 deflects downward around its connection position with the first sliding plate 8, and the right screening plate 7 deflects downward around its connection position with the second sliding plate 9. Both the left screening plate 6 and the right screening plate 7 deflect to a vertical state, allowing the metal scraps on them to fall smoothly. The screening and drainage plate 4 is designed as a separate rotating structure to facilitate the discharge of metal scraps. In practice, to prevent metal scraps from tangling and failing to quickly detach from the screening and draining plate 4, multiple vibrators are installed on the outer wall of the scrap treatment box 2. The vibrators cause the scrap treatment box 2 to vibrate, causing the left screening plate 6 and the right screening plate 7 to deflect into a vertical position, allowing the metal scraps on them to fall smoothly. At the same time, the vibration generated by the vibrators can also accelerate the solid-liquid separation efficiency and improve the solid separation effect during solid-liquid separation. Furthermore, the vibration generated by the scrap treatment box 2 can also be transmitted to the inclined collection platform 1, accelerating the movement of the scraps and cutting fluid on it, so that they can quickly fall into the scrap treatment box 2 through the chip discharge port 3 and the chip discharge trough.

[0022] Example 5 Based on Example 4, such as Figures 1 to 4As shown, a first L-shaped rod 10 is connected to the top of the first slide plate 8, and a second L-shaped rod 11 is connected to the bottom of the second slide plate 9. The first L-shaped rod 10 and the second L-shaped rod 11 are staggered vertically. A first rack 12 is fixed to the bottom of the first L-shaped rod 10, and a second rack 13 is fixed to the top of the second L-shaped rod 11. A gear 14 is provided between the second rack 13 and the first rack 12. The gear 14 rotatably connects to the waste disposal box 2. Both the first rack 12 and the second rack 13 mesh with the gear 14. A cylinder 15 is installed on the side wall of the waste disposal box 2. The telescopic shaft of the cylinder 15 is connected to the first L-shaped rod 10. The cylinder 15 drives the first L-shaped rod 10 to move. L-shaped rod 10 drives the first slide plate 8 to move, the first slide plate 8 drives the left screening plate 6 to move, and at the same time, the first L-shaped rod 10 drives the first rack 12 to move, the first rack 12 drives the gear 14 to rotate, the gear 14 drives the second L-shaped rod 11 to move through the second rack 13, the second L-shaped rod 11 drives the second slide plate 9 to move, and the second slide plate 9 drives the right screening plate 7 to move, so that the left screening plate 6 and the right screening plate 7 can move in a straight line at the same time and in opposite directions. Thus, during solid-liquid separation, the left screening plate 6 and the right screening plate 7 contact to form the screening and discharge plate 4. When discharging metal waste, the left screening plate 6 and the right screening plate 7 separate to form the space required for downward deflection.

[0023] Example 6 Based on Example 5, such as Figures 1 to 4As shown, the left screening plate 6 and the first slide plate 8 are connected by a first hinge, with one end of the first hinge connected to the bottom of the left screening plate 6 and the other end connected to the bottom of the first slide plate 8. The right screening plate 7 and the second slide plate 9 are connected by a second hinge, with one end of the second hinge connected to the bottom of the right screening plate 7 and the other end connected to the bottom of the second slide plate 9. A left winding shaft 16 is rotatably connected to the end of the first slide plate 8 away from the left screening plate 6. A first pull wire 17 is wound on the left winding shaft 16 and moves through the first slide plate 8 to connect to the left screening plate 6. A first motor 18 is installed on the first slide plate 8, and the output shaft of the first motor 18 is driven to drive the left winding shaft 16. A right winding shaft 19 is rotatably connected to the end of the second slide plate 9 away from the right screening plate 7. A second pull wire 20 is wound on the right winding shaft 19 and moves through the second slide plate 9 to connect to the right screening plate 7. A second motor 21 is installed on the second slide plate 9, and the output shaft of the second motor 21 is driven to drive the right winding shaft 19, discharging metal waste. During chip removal, the first motor 18 drives the left winding shaft 16 to rotate and release the first pull wire 17, causing the left screening plate 6 to deflect downwards under its own weight. Simultaneously, the second motor 21 drives the right winding shaft 19 to rotate and release the second pull wire 20, causing the right screening plate 7 to deflect downwards under its own weight. This allows both the left and right screening plates 6 and 7 to deflect to a vertical position under their own weight, enabling the metal chips to be discharged smoothly. After chip removal is completed, the first motor 18 rotates in the opposite direction, causing the left winding shaft 16 to rotate and rewind the first pull wire. 17. The first pull wire 17 pulls the left screening plate 6 upward until the left screening plate 6 contacts the first sliding plate 8 and stops. At the same time, the second motor 21 rotates in the opposite direction, causing the right winding shaft 19 to rotate and wind the second pull wire 20. The second pull wire 20 pulls the right screening plate 7 upward until the right screening plate 7 contacts the second sliding plate 9 and stops. Finally, the cylinder 15 resets, so that the left screening plate 6 and the right screening plate 7 contact to form the screening and draining plate 4, putting it into the screening working state.

[0024] Example 7 Based on Embodiment Six, the processing chamber includes a small-diameter opening 29 and a large-diameter opening 30 arranged sequentially from top to bottom. When the screening and draining plate 4 is in working condition, its size completely covers the small-diameter opening 29, so that metal scraps fall onto the screening and draining plate 4 and do not fall onto the first sliding plate 8 and the second sliding plate 9. The first hinge is installed at the bottom of the left screening plate 6 and the second hinge is installed at the bottom of the right screening plate 7, which facilitates the removal of the first hinge and the second hinge through the bottom opening of the scrap treatment box 2, thereby enabling the removal of the left screening plate 6 and the right screening plate 7 for easy replacement and cleaning.
