Description

Technical Field

[0001] The present invention relates to the technical field of rod cutting for bearing production, and more specifically, to a rod cutting device for bearing production and processing. Background Art

[0002] Slewing bearings are widely used in real industry and are called "machine joints". They are important transmission components required for machines that need to make relative rotational motion between two objects and bear axial force, radial force, and tipping moment at the same time. With the rapid development of the machinery industry, slewing bearings have been widely used in ship equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.

[0003] The main components of the slewing support bearing are produced by various processes such as cutting, free forging, slitting, and die forging using alloy materials. The cutting device used is usually a saw blade cutting method. In the existing cutting process, the debris generated by the friction between the saw blade and the alloy will cause splashing. Its main running trajectory is that the debris is driven by the friction force of the saw blade to move along the rotation direction of the saw blade. The splashed debris falls on the parts of the cutting machine, which will hinder the operation of the equipment parts and affect the normal operation of the equipment. For example, the existing patent publication number: CN118287749B is provided with a "cover 71" to block the splashing debris, but as mentioned above, the running trajectory of the debris is along the running direction of the saw blade, and the debris is easy to fly out from the connection between the "cover 71" and the "cutting disc body 5".

[0043] Both ends of the baffle 6 are provided with a first limiting roller 22, and the edge position of the upper support ring seat 8 and the lower support ring seat 5 close to each other is provided with a first sliding ring groove 20 that is compatible with the first limiting roller 22. The first limiting roller 22 rolls and displaces inside the first sliding ring groove 20, and both ends of the outer side of the upper support ring seat 8 are provided with a second support frame 21 that is fastened to the top of the cutting platform 1.

[0044] The use process of the rod cutting device for bearing production and processing proposed in this embodiment is as follows. When the device is in use, the steel rod 14 to be cut is supported on the top of the two groups of first support frames 2. At this time, the steel rod 14 to be cut passes through both sides of the lower support ring seat 5 and is clamped and fixed by two groups of clamping mechanisms 13. It should be particularly noted that the first support frame 2 is any support structure in the prior art, and its main function is to support the steel rod 14 to be cut and adjust the position height. At the same time, the clamping mechanism 13 is any clamping structure in the prior art, and its main function is to position and clamp the outer side of the steel rod 14 to be cut, so as to keep the position structure of the steel rod 14 to be cut stable.

[0045] The driving motor 10 is started to drive the cutting blade 17 to rotate, and the water pump 3 is started synchronously to extract the coolant in the water collecting bucket 403, so as to be transported to the top of the steel rod 14 to be cut through the conduit 7;

[0046] By starting the hydraulic cylinder 11, the driving motor 10 on the top of the support seat 12 is driven to move longitudinally as a whole, thereby driving the cutting blade 17 to move longitudinally horizontally, so that the cutting blade 17 is constantly approaching the steel rod 14 to be cut and then cuts the steel rod 14 to be cut;

[0047] During the displacement of the cutting blade 17, the support plate 16 is driven to follow the displacement by the driving motor 10, and then the baffle 6 is driven to follow the displacement by the displacement of the support plate 16. At this time, the support plate 16 always performs horizontal longitudinal displacement along one side of the top of the lower support ring seat 5, and due to the mutual hinge between the plurality of baffle plates 6, the baffle plate 6 can be deflected and displaced along the top of the lower support ring seat 5, and then a relatively closed area is formed by the annular structure of the baffle plate 6 and the support plate 16 and the lower support ring seat 5 and the upper support ring seat 8. The splashing debris generated by the cutting blade 17 during the cutting of the steel rod 14 to be cut will follow the running direction of the cutting blade 17. It will be blocked by the area formed by the baffle plate 6, the lower support ring seat 5, the upper support ring seat 8, and the support plate 16, and will always remain in the area, thereby preventing the splashing of debris from affecting the operation of the equipment.

[0048] Furthermore, when the baffle 6 moves, the brush 909 fits against the inner wall of the baffle 6, and then the baffle 6 is cleaned by the brush 909 as it moves, and the displacement of the baffle 6 drives the squeezing roller 904 on the top of the connecting rod 905 to follow the displacement, and when the squeezing roller 904 moves to the position of the linkage wedge block 907, it generates downward pressure on the linkage wedge block 907, thereby driving the first slider 906 connected to the linkage wedge block 907 to move downward, thereby driving the supporting connecting rod 901 to move downward as a whole;

[0049] The return spring 902 is compressed by the downward displacement of the support link 901 to generate a rebound force. At the same time, the brush 909 is driven to move downward by the support link 901, thereby generating a downward cleaning state for the inner side of the baffle 6;

[0050] Since the bottom end position height of the squeezing roller 904 is lower than the bottom end position height of the linkage wedge block 907, when the squeezing roller 904 continues to move away from the top of the linkage wedge block 907, the supporting link 901 as a whole still has space to move upward, and is acted upon by the rebound force of the return spring 902. When the squeezing roller 904 is separated from the linkage wedge block 907, the rebound force of the return spring 902 acts on the supporting link 901 as a whole, causing the supporting link 901 as a whole to instantly move upward to produce a vibration effect. Furthermore, through the vibration effect, the debris and impurities attached to the brush 909 are cleaned by vibration, thereby realizing the self-cleaning function of the brush 909.

[0051] When the cutting blade 17 has finished cutting the steel rod 14, the hydraulic cylinder 11 drives the driving motor 10 to move in the reverse direction as a whole, and then the brush 909 cleans the inner side of the baffle 6 for a second time, thereby improving the cleaning efficiency.

[0052] During the cutting process of the cutting blade 17, the coolant outputted through the conduit 7 cools down the cutting position of the cutting blade 17 and the steel rod 14 to be cut, and at the same time washes the generated debris and guides it to the interior of the separation box 401. Through the guiding effect of the guide plate 402, the debris containing the coolant is guided to the position of the filter screen plate 405 for screening and separation, wherein the large particles of debris are discharged from the position of the second discharge port 407, while the small particles and the finely crushed debris follow the coolant and fall into the position of the industrial filter cloth 404, and at this time, the industrial filter The cloth 404 performs secondary filtration on the coolant, so that the small particulate matter and fine debris contained in the coolant are filtered out and discharged from the position of the first discharge port 406. The first discharge port 406 is arranged at the bottom of the filter screen plate 405 to prevent the high-temperature debris generated during the cutting process of the cutting blade 17 from directly contacting the industrial filter cloth 404, thereby avoiding the phenomenon of burning through the industrial filter cloth 404. At the same time, the industrial filter cloth 404 realizes deep filtration of the coolant, so that the coolant can quickly flow back to the inside of the water collecting bucket 403 and be recycled.

[0053] The specific implementation methods of this embodiment are described above, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms inspired by this embodiment, all of which are within the protection of this embodiment.
