Description

Technical Field

[0001] This invention relates to the field of cutting machine tool technology, specifically to an intelligent cutting machine tool for bearing steel pipes. Background Technology

[0002] As a core transmission component of mechanical equipment, the precision and lifespan of bearings directly depend on the processing quality of the bearing steel tubes. Bearing steel tubes undergo multiple processes including cutting, grinding, and heat treatment. Among these, cutting is the key step that determines the outer diameter, wall thickness, and surface finish of the steel tube, decisively impacting subsequent assembly accuracy and bearing operational stability. With the ever-increasing precision requirements of high-end equipment, traditional cutting equipment can no longer meet the demands. Intelligent cutting machine tools for bearing steel tubes have emerged to address this need. By integrating CNC systems, servo drive mechanisms, and online detection modules, they achieve real-time optimization of cutting parameters and precise control of processing accuracy, becoming the mainstream equipment in the bearing manufacturing field.

[0003] During the cutting process, the cutting wheel contacts the outer surface of the bearing steel tube at a rotation speed of 500-1500 r / min, removing excess metal through mechanical friction and shearing. During this process, the contact area between the cutting wheel and the steel tube will generate a large amount of heat due to friction and the conversion of cutting work. If the heat is not cooled in time, it will not only cause the material of the cutting wheel to soften and the wear rate to accelerate, but also cause local thermal deformation of the bearing steel tube, resulting in dimensional deviations in the machining, and even causing oxide layers or microcracks to appear on the surface of the steel tube, which will seriously affect the effect of subsequent heat treatment and the service life of the bearing.

[0004] To address the issue of cooling in the cutting zone, existing intelligent cutting machine tools are generally equipped with external spray cooling systems. The technical solution involves installing cooling water pipes next to the cutting mechanism, with several spray holes opened in the pipes facing the outer surface of the bearing steel tube. The cooling water pump pressurizes the cooling water (usually emulsion or deionized water) and sprays it onto the outer surface of the bearing steel tube through the spray holes at a pressure of 0.2-0.5 MPa. The aim is to indirectly remove the heat from the contact area between the cutting wheel and the steel tube through heat exchange between the cooling water and the steel tube.

[0005] To ensure cutting accuracy, the clearance between the cutting wheel and the outer surface of the steel pipe must be strictly controlled within 0.1-0.5mm. Due to the narrow gap and the airflow barrier formed by the high-speed rotation of the cutting wheel, water flow is hindered, resulting in the externally sprayed cooling water only covering the outer surface of the steel pipe, with less than 5% of the water penetrating into the cutting gap. The direct contact area between the cutting wheel and the steel pipe cannot be effectively cooled, resulting in a significantly insufficient cooling effect. Furthermore, most of the externally sprayed cooling water is thrown out by the centrifugal force generated by the high-speed rotation of the cutting wheel, with a contact time with the cutting area of ​​less than 0.5 seconds, leading to low heat exchange efficiency. Therefore, this invention provides an intelligent cutting machine tool for bearing steel pipes. Summary of the Invention

[0013] Compared with the prior art, the present invention provides an intelligent cutting machine tool for bearing steel tubes, which has the following beneficial effects: This invention employs a bidirectional cooling design with a first nozzle and a second nozzle. The second nozzle extends through the baffle cover into the steel pipe, directly spraying cooling water onto the contact area between the cutting wheel and the steel pipe. Simultaneously, the two ends of the steel pipe are sealed by push plates and the baffle cover to form a "temporary cavity," allowing the cooling water to flow out slowly only through the cutting gap. This significantly extends the contact time between the cooling water and the cutting wheel and steel pipe, thereby improving heat exchange efficiency. 2. The threaded block, push rod, and nozzle form an intelligent follow-up structure of "mechanical feedback + CNC linkage": When the first threaded rod drives the threaded block to move along the cutting direction, the CNC system synchronously monitors the contact position between the cutting wheel and the steel pipe. Through the elastic cooperation of the torsion spring and the second spring, the push rod automatically pushes the first fixed pipe, so that the first nozzle and the second nozzle are always aligned with the core cutting area. Compared with the problem of "cooling failure after the cutting position is offset" in traditional fixed spraying, this design realizes intelligent tracking of "where the cutting is, the cooling is". There is no need to manually adjust the nozzle angle. It ensures that the core heat-generating area is continuously covered by cooling water throughout the cutting process. The wear rate of the cutting wheel is reduced by 40%-60%, and the replacement cycle is extended from 4-6 hours to 12-15 hours. 3. When the threaded block drives the cutting wheel to move, the push rod pushes the first fixed pipe synchronously with the cutting process, so that the first nozzle and the second nozzle are always aligned with the cutting position, avoiding the problem of ineffective spraying in traditional fixed spraying, and reducing the amount of cooling water wasted while improving the cooling effect; 4. After cutting, the clamping block remains pressed against the bearing ring. The moving plate is moved horizontally by the electric telescopic rod, and the piston cylinder is rotated 90° by the fourth motor. Then, the piston plate is reset to form a negative pressure, which causes the clamping block to loosen and release the bearing ring, completing the automatic material collection. This design completely replaces the traditional manual material handling (which requires a 10-15 second stop per piece), shortening the material handling time to 2-3 seconds per piece, and increasing the production capacity of a single machine by 15%-20%. At the same time, it avoids the risk of burns caused by manual contact with the high-temperature bearing ring, improving production safety.

[0020] Please combine Figures 1 to 11 As shown, the present invention provides an intelligent cutting machine tool for bearing steel pipes. The machine tool includes a support plate 10, a fixed clamping plate 96 fixedly installed on the support plate 10, a movable clamping plate 95 arranged directly above the fixed clamping plate 96, and fixed blocks fixedly installed at both ends of the movable clamping plate 95 along its length. A third slide rod 98 is fixedly installed on the support plate 10, one end of which passes through the interior of one of the fixed blocks and is slidably connected to the fixed block. A third threaded rod 97 is rotatably installed on the support plate 10, one end of which passes through the interior of another fixed block and is threadedly connected to the fixed block. A sixth motor 94 is fixedly installed on the lower surface of the support plate 10, and the output end of the sixth motor 94 is fixedly connected to the bottom end of the third threaded rod 97. Activating the sixth motor 94 drives the third threaded rod 97 to rotate, causing the movable clamping plate 95 to descend or rise, clamping or releasing the steel pipe 11. The support plate 10 is also provided with a push plate 90, on which a first protrusion 901 and a second protrusion 902 are fixedly installed. The support plate 10 is provided with a sliding groove 101. A second sliding rod 93 is fixedly installed on the lower surface of the support plate 10. One end of the second sliding rod 93 passes through the interior of the second protrusion 902 and is slidably connected to the second protrusion 902. A second threaded rod 92 is rotatably installed on the lower surface of the support plate 10. One end of the second threaded rod 92 passes through the interior of the first protrusion 901 and is threadedly connected to the first protrusion 901. A fifth motor 91 is fixedly installed on the lower surface of the support plate 10. The output end of the fifth motor 91 is fixedly connected to one end of the second threaded rod 92. A gantry frame 12 is fixedly installed on the upper surface of the support plate 10. A track frame 13 is fixedly installed on the gantry frame 12. A threaded block 72 is slidably installed inside the track frame 13. A first threaded rod 73 is rotatably installed inside the track frame 13. One end of the first threaded rod 73 passes through the interior of the threaded block 72 and is threadedly connected to the threaded block 72. A third motor 77 is fixedly installed on one end of the track frame 13. The output end of the third motor 77 is fixedly connected to one end of the first threaded rod 73. A first sliding rod 74 is fixedly installed inside the track frame 13. One end of the first sliding rod 74 passes through the interior of the threaded block 72 and is slidably connected to the threaded block 72. A second motor 71 is fixedly mounted on the threaded block 72, and a cutting wheel 70 is fixedly mounted on the output end of the second motor 71; A pair of track plates 14 are fixedly installed on one end of the support plate 10 along its length. A movable plate 80 is installed between the two track plates 14. A slider 801 is fixedly installed at both ends of the movable plate 80 along its length. The two sliders 801 are slidably connected to the two track plates 14 respectively. An electric telescopic rod 81 is fixedly installed between the two track plates 14. The movable end of the electric telescopic rod 81 is fixedly connected to the movable plate 80. A piston cylinder 20 is installed on the movable plate 80. A piston plate 21 is fixedly and slidably installed inside the piston cylinder 20. A screw 23 is rotatably installed inside the piston cylinder 20. A first motor 22 is fixedly installed on one end of the piston cylinder 20. The output end of the first motor 22 is fixedly connected to one end of the screw 23. A liquid storage tank 60 is provided on one side of the support plate 10. One end of the piston cylinder 20 is connected to the bottom of the liquid storage tank 60 through a first connecting pipe assembly. A control valve 63 is fixedly installed on the first connecting pipe assembly. One or more blocking covers 30 are installed on one side of the piston cylinder 20 via a connecting plate 202. An insert block 31 is fixedly installed on one side of the blocking cover 30, and a channel 301 is opened on the blocking cover 30. One or more second connecting pipe assemblies are fixedly installed on the piston cylinder 20. A one-way valve 46 is fixedly installed on each second connecting pipe assembly. A first nozzle 40 and a second nozzle 41 are fixedly installed on one end of each second connecting pipe assembly. The second nozzle 41 passes through the channel 301. First, place the steel pipe 11 between the movable clamping plate 95 and the fixed clamping plate 96, and make one end of the steel pipe 11 fit against the push plate 90. After the fifth motor 91 is started, the push plate 90 pushes one end of the steel pipe 11 to move until the other end of the steel pipe 11 fits against the blocking cover 30. Then, the movable clamping plate 95 moves downward to clamp and fix the steel pipe 11 for cutting. When the cutting wheel 70 cuts the steel pipe 11, the first motor 22 drives the screw 23 to rotate, causing the piston plate 21 to move inside the piston cylinder 20. During the movement of the piston plate 21, the cooling water in the piston cylinder 20 is squeezed and transported to the first nozzle 40 and the second nozzle 41 through the second connecting pipe assembly. The first nozzle 40 sprays the cooling water onto the outer surface of the steel pipe 11, which can quickly cool the upper part of the steel pipe 11 when the cutting wheel 70 cuts it. The second nozzle 41 is located inside the steel pipe 11 and directly sprays the cooling water onto the outer surface of the steel pipe 11. Cooling water is sprayed onto the cutting wheel 70 to directly cool it. The cooling water that detaches from the cutting wheel 70 remains inside the steel pipe 11. Both ends of the steel pipe 11 are sealed along its length, and the cooling water can only flow out through the cutting gap. The cooling water remaining inside the steel pipe 11 can continuously cool the cutting wheel 70 and the steel pipe 11. The high-speed rotation of the cutting wheel 70 will not cause the cooling water to separate directly from the cutting wheel 70, thus affecting the cooling effect. This significantly increases the contact time between the cooling water and the cutting wheel 70, effectively improving the cooling effect. It should be noted that when multiple second connecting pipe assemblies are provided, multiple one-way valves 46 are also provided. The connection ends of multiple second connecting pipe assemblies and piston cylinder 20 are distributed at equal intervals along the length of piston cylinder 20. Multiple one-way valves 46 open sequentially. After piston plate 21 passes the connection end of the first second connecting pipe assembly and piston cylinder 20, the one-way valve 46 on the next second connecting pipe assembly opens. The one-way valve 46 can also be controlled to open and close by using elastic force. The required force in multiple one-way valves 46 can be increased sequentially. Example

[0021] The second connecting pipe assembly includes a first fixed pipe 43, a first flexible hose 44, and a second fixed pipe 45; the second fixed pipe 45 is fixedly connected to the piston cylinder 20, the first fixed pipe 43 is fixedly connected to the first nozzle 40 and the second nozzle 41, and the first flexible hose 44 is fixedly disposed between the first fixed pipe 43 and the second fixed pipe 45. A movable block 42 is fixedly installed on the second nozzle 41. The movable block 42 is slidably disposed in the channel 301. A second spring 47 is fixedly installed between the movable block 42 and the blocking cover 30. A push rod 75 is rotatably mounted on the threaded block 72. A torsion spring 76 is fixedly mounted between the push rod 75 and the threaded block 72, and the elastic force of the torsion spring 76 is greater than the elastic force of the second spring 47. After the first threaded rod 73 rotates, the threaded block 72 can move along the axial direction of the first threaded rod 73. The cutting wheel 70 then cuts the steel pipe 11 supported on the support plate 10. After the cutting wheel 70 contacts the steel pipe 11, the push rod 75 then contacts the first fixed pipe 43. The push rod 75 will then push the first fixed pipe 43 to move, so that the cooling water sprayed from the first nozzle 40 and the second nozzle 41 can directly contact the cutting position, which can not only improve the cooling effect, but also reduce the use of cooling water. Example

[0022] A fourth motor 82 is fixedly installed on the movable plate 80. The piston cylinder 20 is rotatably connected to the movable plate 80 through the connector 201. The output end of the fourth motor 82 is fixedly connected to the connector 201. Each insert 31 has a closed cavity 311 inside, and a movable block 34 is slidably installed inside the closed cavity 311. A first spring 35 is fixedly installed between the movable block 34 and the insert 31. The movable block 34 is fixedly connected to a clamping block 32 through a connecting block 33. A liquid storage tube 50 is fixedly installed on the piston cylinder 20, and one end of the liquid storage tube 50 is connected to the inside of the piston cylinder 20. A sealing plate 24 is fixedly installed on the piston plate 21. An annular tube 51 is fixedly connected to each blocking cover 30. The annular tube 51 is connected to the closed cavity 311 through a connecting tube 52. A first connecting tube 53 is fixedly connected to the annular tube 51. The liquid storage tube 50 is fixedly connected to the first connecting tube 53 through a second connecting tube 54. Before cutting the steel pipe 11, the piston plate 21 first squeezes some of the cooling water in the piston cylinder 20 into multiple closed cavities 311. After the cooling water in the closed cavities 311 increases, multiple clamping blocks 32 move to the outside of the insert block 31 until they contact and press against the inner surface of the steel pipe 11. After the piston plate 21 passes the connection end between the liquid storage pipe 50 and the piston cylinder 20, the sealing plate 24 seals the connection end between the liquid storage pipe 50 and the piston cylinder 20, so that the clamping blocks 32 remain in a state of tight contact with the inner surface of the steel pipe 11. The first connecting tube assembly consists of a second hose 61 and a third fixed tube 62. The third fixed tube 62 is fixedly connected to one end of the piston cylinder 20. The bottom end of the second hose 61 is fixedly connected to the liquid storage tank 60, and the top end of the second hose 61 is fixedly connected to one end of the third fixed tube 62. After one cutting action is completed, the cut bearing ring is clamped by the clamping block 32. Then, the movable end of the electric telescopic rod 81 retracts. After reaching the appropriate position, the fourth motor 82 drives the connector 201 to rotate 90°, so that the insertion block 31 faces directly downward. The first motor 22 drives the screw 23 to rotate, so that the piston plate 21 is reset. After the piston plate 21 is reset, the inside of the piston cylinder 20 is a cavity and under negative pressure. The cooling water in the liquid storage pipe 50 returns to the piston cylinder 20. Under the elastic force of the first spring 35, the clamping block 32 moves towards the inside of the insertion block 31. The bearing ring, which loses its force, disengages from the insertion block 31, completing the material collection. A collection box or conveyor belt can be set directly below the bearing ring to collect or transfer the bearing ring. During the process of piston cylinder 20 rotating and resetting, control valve 63 opens, drawing cooling water from storage tank 60 into piston cylinder 20, ready for the next cutting action.
