DETAILED DESCRIPTION

[0019] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 7As shown, in the embodiment of the present invention, a metal cutting device for parts processing includes a processing table 1, support columns 2 are installed on both sides of the processing table 1, telescopic cylinders 3 are arranged on the top of the two support columns 2, support frames 4 are installed on the top of the telescopic cylinders 3, the support frames 4 are arranged above the processing table 1, and a protective cover 5 is fixedly connected to the bottom end of the support frame 4, a protective assembly is arranged inside the protective cover 5, a cutting blade 6 is rotatably connected to the inside of the protective cover 5 through a first rotating shaft 8, and a motor 7 is installed at one end of the first rotating shaft 8; Among them, the protection component includes a guide groove 17 and a liquid outlet 18 opened inside the protective cover 5, the liquid outlet 18 is arranged at the bottom end of the guide groove 17, the liquid outlet 18 is evenly arranged, and a fourth connecting pipe 16 is arranged at the top of the guide groove 17, the fourth connecting pipe 16 passes through the interior of the protective cover 5 and extends to the interior of the support frame 4, and a third connecting pipe 15 is installed at one end of the fourth connecting pipe 16 away from the protective cover 5, and the bottom end of the third connecting pipe 15 is fixedly connected to the second connecting pipe 14, and the second connecting pipe 14 is embedded in the processing table 1, and a water pump 12 is installed at one end of the second connecting pipe 14, and the side of the water pump 12 away from the second connecting pipe 14 is connected to the first connecting pipe 13, and a liquid storage chamber 10 is arranged at one end of the first connecting pipe 13, and the liquid storage chamber 10 is opened inside the processing table 1; Existing: CN218611945U discloses a metal cutting device that is easy to clean debris. This patent discloses the processing table 1, support column 2, telescopic cylinder 3, support frame 4 and cutting blade 6 proposed in this application document. This technical means is not described in detail here.

[0021] When using the metal cutting device to process parts, the water pump 12 is controlled to start, and the water inside the liquid storage chamber 10 is drawn through the first connecting pipe 13 and discharged into the interior of the fourth connecting pipe 16 through the second connecting pipe 14 and the third connecting pipe 15, and then diverted through the guide groove 17 and finally discharged from the liquid outlet 18. Since the protective cover 5 is located outside the cutting blade 6 and the liquid outlets 18 are evenly distributed, a circle of water is formed around the outside of the cutting blade 6 when the water source is discharged to block the metal particles and dust generated during the cutting process, which not only improves the working environment but also ensures the health of nearby workers.

[0022] like Figure 6 As shown, air inlet holes 19 are evenly opened inside the protective cover 5 , and the air inlet holes 19 are connected to the liquid outlet holes 18 .

[0023] When the water source inside the guide groove 17 is discharged downward, due to the pressure difference, air enters from the air inlet 19 and mixes with the water inside the liquid outlet 18 to form bubbles and disperse in the water, thereby reducing the pressure of the water when it is discharged, preventing the water from contacting the surface of the first filter plate 9 and splashing after the water is discharged from the liquid outlet 18, thereby improving the cleanliness of the working environment.

[0024] like Figure 6 As shown, a first filter screen 20 is installed at the bottom end of the liquid outlet 18 .

[0025] Further reduce the impact force when water is discharged.

[0026] like Figure 6 As shown, a second filter screen 30 is installed at the bottom end of the air inlet 19 .

[0027] The metal particles and dust in the air are filtered to prevent them from entering the air inlet 19.

[0028] like Figure 1 and Figure 2 As shown, the third connecting pipe 15 is configured as a bellows.

[0029] The third connecting pipe 15 is stretched during the movement of the support frame 4 , which not only ensures a stable connection between the second connecting pipe 14 and the fourth connecting pipe 16 , but also prevents the water pipe from being too long and randomly distributed on the top of the processing table 1 .

[0030] like Figure 1 and Figure 2 As shown, a first filter plate 9 is installed on the top of the processing table 1, and the first filter plate 9 is arranged below the cutting blade 6.

[0031] During metal cutting, the metal particles in the water are filtered through the first filter plate 9, and the filtered water is then collected in the liquid storage chamber 10, so as to facilitate its recycling and save water resources.

[0032] like Figure 2 As shown, a second filter plate 11 is disposed below the first filter plate 9 , the second filter plate 11 is installed inside the liquid storage chamber 10 , and a scraping assembly is disposed on the top of the second filter plate 11 .

[0033] The recovered water is filtered again to improve the cleanliness of the water.

[0035] During metal cutting, when the water source inside the liquid storage chamber 10 enters the first connecting pipe 13, the rotating plate 26 is caused to rotate. The rotation of the rotating plate 26 drives the rotation of the second rotating shaft 25. The rotation of the second rotating shaft 25 drives the rotation of the second bevel gear 24. The rotation of the second bevel gear 24 drives the rotation of the first bevel gear 23. The rotation of the first bevel gear 23 drives the rotation of the threaded rod 22. The rotation of the threaded rod 22 drives the scraper 21 to reciprocate at the top of the second filter plate 11, scraping the metal debris accumulated on the top of the second filter plate 11, preventing the metal debris from accumulating on the top of the second filter plate 11 after the device has been used for a period of time, affecting the filtering effect, and scraping the metal debris and impurities on the top of the second filter plate 11 to both sides to ensure the filtering effect of the second filter plate 11.

[0036] like Figure 7 As shown, the scraper 21 is evenly provided with protruding rods 27 , and the outer wall of each protruding rod 27 is fixedly connected to a limiting plate 28 , which is slidably installed inside the scraper 21 , and a spring 29 is provided between the limiting plate 28 and the scraper 21 .

The two ends of the protruding rod 27 contact the bottom end of the first filter plate 9 and the top end of the second filter plate 11 respectively. The elastic potential energy of the spring 29 causes the protruding rod 27 to move up and down reciprocatingly, thereby striking the first filter plate 9 and the second filter plate 11, which helps to separate the metal debris inside the first filter plate 9 and the second filter plate 11, thereby ensuring the stability of the filtration of the first filter plate 9 and the second filter plate 11.

[0038] A cutting method of a metal cutting device for parts processing, comprising the following steps: S1: When using the metal cutting device to process parts, first place the workpiece on the top of the first filter plate 9, then control the telescopic cylinder 3 to contract and drive the support frame 4 to move downward, the movement of the support frame 4 drives the movement of the protective cover 5, and the movement of the protective cover 5 drives the cutting blade 6 to move downward to cut the workpiece; S2: During cutting, the water pump 12 is started, and the water in the liquid storage chamber 10 is drawn through the first connecting pipe 13 and discharged into the fourth connecting pipe 16 through the second connecting pipe 14 and the third connecting pipe 15, and then is guided through the guide groove 17 and finally discharged from the liquid outlet 18, forming a water curtain around the outside of the cutting blade 6 to block metal particles and dust; S3: When the water source inside the liquid storage chamber 10 enters the first connecting pipe 13, the rotating plate 26 is caused to rotate, and the rotation of the rotating plate 26 drives the rotation of the second rotating shaft 25, and the rotation of the second rotating shaft 25 drives the rotation of the second bevel gear 24, and the rotation of the second bevel gear 24 drives the rotation of the first bevel gear 23, and the rotation of the first bevel gear 23 drives the rotation of the threaded rod 22, and the rotation of the threaded rod 22 drives the scraper 21 to reciprocate at the top of the second filter plate 11, scraping the metal debris accumulated on the top of the second filter plate 11 to both sides; S4: During the movement of the scraper 21, the movement of the scraper 21 drives the movement of the protruding rod 27. The two ends of the protruding rod 27 contact the bottom end of the first filter plate 9 and the top end of the second filter plate 11 respectively. The elastic potential energy of the spring 29 causes the protruding rod 27 to move up and down reciprocatingly, thereby striking the first filter plate 9 and the second filter plate 11, which helps to separate the metal debris inside the first filter plate 9 and the second filter plate 11.
