Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, specifically to a metal cutting device that facilitates chip removal. Background Technology

[0002] Metal cutting generates various types of chips, including ribbon-shaped, spiral-shaped, and powdery chips. Traditional cleaning devices have limitations and rely heavily on manual cleaning at regular intervals, which is time-consuming, inefficient, and poses safety hazards. Some simple chip removal structures are difficult to adapt to different types of chips, which can easily lead to accumulation and affect machining accuracy.

[0003] Patent application CN202320122985.X discloses a metal cutting device for easy debris removal, including a processing table; a concave surface is provided at the upper end of the processing table, and a placement plate is fixedly installed in the concave surface. Multiple through holes are provided at the upper end of the placement plate. Two inclined surfaces are provided inside the processing table below the placement plate, and a groove is provided between the two inclined surfaces. Two brushes are provided, located on opposite sides of the processing table and connected to the processing table via a first telescopic cylinder. A cutting blade is located directly above the processing table. During cutting, the workpiece is placed on the placement plate, and then the cutting blade cuts the workpiece. Some of the debris generated during the cutting process leaks into the groove through the through holes in the placement plate. For debris that does not leak into the groove, the brushes can clean the debris remaining on the placement plate, allowing the debris remaining on the placement plate to leak into the groove through the through holes.

[0004] However, this patent also has the following shortcomings: when cleaning metal debris through the through holes of the placement plate, longer chips generated from cutting different metals are easily stuck in the holes, thus getting stuck around the workpiece and affecting the cleaning of both long and short chips; at the same time, the clumps formed by the discharged chips and cutting fluid will accumulate on the inclined surface, further hindering chip cleaning and reducing the overall cleaning efficiency.

Scraper 441, with tension belt 442 fixedly connected to its outer surface, which is used to pull scraper 441.

[0024] The limiting slider 3 is slidably connected to the cutting box 2. A hydraulic pump 31 is fixedly connected to the upper surface of the limiting slider 3. A moving device 32 is fixedly connected to the output end of the hydraulic pump 31. A cutting structure 33 is slidably connected to the outer surface of the moving device 32. The cutting structure 33 is used to cut the workpiece 6.

[0025] The cutting mechanism 4 also includes a limiting frame 41, which is fixedly connected to the inner wall of the base support 1. A vibrator 411 is fixedly connected to the inner wall of the limiting frame 41, and an inclined plate 412 is fixedly connected to the lower surface of the vibrator 411. A limiting frame 42 is snapped onto the outer surface of the cutting box 2, and a rectangular column 43 is snapped onto the inner wall of the cutting box 2. A screw 431 is rotatably connected inside the rectangular column 43, and a rectangular telescopic tube 432 is fixedly connected to the outer surface of the rectangular column 43. A sliding frame 44 is slidably connected to the outer surface of the scraper 441, and a telescopic baffle 443 is fixedly connected to the outer surface of the scraper 441. The telescopic baffle 443 is used to protect the sliding frame 44.

[0026] The lower surface of the limiting frame 41 is flush with the lower surface of the base bracket 1. The inclined plate 412 is fixedly connected to the guide inclined groove 413. The tension band 414 is slidably connected to the inner wall of the cutting box 2. The tension band 414 is fixedly connected to the inner wall of the cutting box 2. The upper surface of the rectangular column 43 is flush with the upper surface of the rectangular telescopic tube 432. The lower surface of the limiting frame 42 is in contact with the lower surface of the rectangular column 43. The limiting frame 42 is used to limit the rectangular column 43.

[0027] The outer surface of the rectangular telescopic tube 432 is fixedly connected to the outer surface of the right-angle clamp 433. The outer surface of the right-angle clamp 433 is in contact with the outer surface of the workpiece 6. The side of the second limiting frame 434 is in contact with the side of the workpiece 6. The outer surface of the first corrugated tube 436 is in contact with the outer surface of the right-angle clamp 433. The outer surface of the first corrugated tube 436 is fixedly connected to the outer surface of the second limiting frame 434. The threaded post 435 is used to fix the second limiting frame 434.

[0028] The lower surface of the sliding frame 44 is fixedly connected to the upper surface of the limiting slider 3. The tension band 442 is fixedly connected to the inner wall of the sliding frame 44. The lower surface of the telescopic baffle 443 is flush with the lower surface of the sliding frame 44. The limiting frame 434 has a through hole for material discharge. The scraper 441 is used to clean the right-angle clamp 433. When the right-angle clamp 433 is moved by the screw 431, the rectangular telescopic tube 432 protects the screw 431 to prevent chips from jamming the screw 431. When the scraper 441 moves inside the sliding frame 44, the telescopic baffle 443 protects the tension band 442 to prevent chips from getting stuck inside the sliding frame 44.

[0029] When cleaning metal chips through the through-hole of the placement plate, longer chips generated from cutting different metals are easily stuck in the hole, affecting the cleaning of both long and short chips. Therefore, the cutting mechanism 4 needs to limit the workpiece 6 while simultaneously using the gap between the right-angle clamp 433 and the guide groove 413 to discharge the chips, so that the chips do not accumulate on the surface of the workpiece.

[0030] The working principle of this embodiment is as follows: When using this metal cutting device that facilitates chip removal, the workpiece 6 is placed on the surface of the right-angle clamping plate 433. At this time, the screw 431 rotates, driving the two symmetrically arranged right-angle clamping plates 433 to move inward, thereby clamping the two sides of the workpiece 6. Simultaneously, it pushes the second limiting frame 434 to move on the surface of the right-angle clamping plate 433, so that the surface of the second limiting frame 434 contacts the side of the workpiece 6. At this time, by rotating the threaded column 435, the second limiting frame 434 is pushed in the opposite direction, fixing the position of the second limiting frame 434. Thus, the second limiting frame 434 cooperates with the right-angle clamping plate 433 to fix the position of the workpiece 6. While the right-angle clamping plate 433 moves inward, it pushes the first scraper 441 to slide inside the sliding frame 44. The scraper 441 is tensioned by the tension belt 442, so that the scraper 441 contacts the surface of the right-angle clamp 433. At this time, the vibrator 411 is activated, and the guide groove 413 is vibrated by the inclined plate 412, so that the tension belt 414 moves up and down. The guide groove 413 is reset while vibrating by the tension belt 414. At this time, the hydraulic pump 31 pushes the moving device 32 and the cutting structure 33 to move downward, so that the cutting structure 33 cuts the workpiece 6. The chips are discharged through the gap between the right-angle clamp 433 and the guide groove 413. Some fall directly, and the other part falls through the vibrating inclined surface of the guide groove 413 and falls into the inside of the collar 51, which facilitates the cleaning of chips and prevents long chips from getting stuck around the workpiece 6.

[0031] Example 2: Please refer to Figures 7-9 Based on Embodiment 1, the present invention provides a technical solution: the cleaning mechanism 5 includes a collar 51, which is engaged with the hydraulic pump 31. A scraper 2 511 is fixedly connected to the outer surface of the collar 51. A U-shaped frame 512 is fixedly connected to the upper surface of the scraper 2 511. A waste trough 52 is engaged with the outer surface of the base bracket 1. A rotating shaft 53 is fixedly connected to the inner wall of the waste trough 52. A rotating plate 54 is rotatably connected to the outer surface of the rotating shaft 53. A protective cover 541 is fixedly connected to the outer surface of the rotating plate 54. A hydraulic device 542 is rotatably connected to the outer surface of the rotating plate 54. A corrugated pipe 2 543 is sleeved on the outer surface of the hydraulic device 542. The corrugated pipe 2 543 is used to protect the hydraulic device 542.

[0032] The outer surface of scraper 511 contacts the outer surface of guide groove 413, the upper surface of U-shaped frame 512 contacts the lower surface of limit frame 434, the outer surface of rotating plate 54 contacts the inner wall of waste trough 52, hydraulic device 54 is fixedly connected to the inner wall of waste trough 52, hydraulic device 542 is used to push rotating plate 54, when long chips are squeezed and clamped by rotating plate 54, protective cover 541 protects the rotating groove of hydraulic device 542, so that long chips can only fall through the gap between rotating plate 54 and guide groove 413, when hydraulic device 542 pulls rotating plate 54, the movement of hydraulic device 542 is protected by bellows 543.

[0033] The clumps formed by the discharge of chips and cutting fluid will accumulate on the surface of the guide groove 413, further hindering chip removal. Therefore, the cleaning mechanism 5 is required to scrape the guide groove 413. At the same time, the rotating plate 54 clamps the long chips and pulls them downward, thereby assisting the cutting mechanism 4 in cleaning the long chips around the workpiece 6.

[0034] The working principle of this embodiment is as follows: When using this metal cutting device that facilitates chip removal, after clamping the workpiece 6, during metal chip cutting, the long chips generated by cutting gradually descend due to gravity and fall into the gap between the rotating plate 54 and the guide groove 413, and the gap between the rotating plate 54 and another rotating plate 54. At this time, the rotating plate 54 is rotated around the rotating shaft 53 by the hydraulic device 542. The long chips located on the surface of the guide groove 413 are clamped by the narrowing gap between the rotating plate 54 and the guide groove 413, while the long chips located in the gap between the rotating plate 54 and another rotating plate 54 are clamped by the narrowing gap. This pulls the long chips downwards, causing them to fall into the waste trough 52. As the long chips on the surface of the guide chute 413 move downwards, they also pull the mixture of short chips and cutting fluid on the surface of the guide chute 413 downwards. After the chips are cut, the limiting slider 3 is pushed, causing the collar 51 and scraper 511 to move. The scraper 511 scrapes the two inclined surfaces of the guide chute 413, causing the short chips on the surface of the guide chute 413 to fall. As the scraper 511 moves, the two symmetrically arranged scrapers 511 are connected by the U-shaped frame 512, so that the two scrapers 511 are on the same plane during scraping.
