Description

Technical Field

[0001] This invention relates to the field of lubrication technology for straightening machines, and particularly to a lubrication system for straightening machines for titanium and titanium alloy plates and strips. Background Technology

[0002] Titanium and titanium alloy strip straightening machines are commonly used to process titanium and its alloy strips to improve material flatness, remove internal stress, and ensure smooth subsequent processing. The application of straightening machines is mainly concentrated in the production process of metal strips, especially in high-strength, low-ductility, and easily deformable materials such as titanium and titanium alloys. Current straightening equipment primarily relies on roller straightening mechanisms, applying pressure through a roller system to straighten bent or deformed portions of the titanium alloy strip to a flat state. Lubrication of the pressure rollers is a crucial operation, especially when handling high-strength materials like titanium and titanium alloys, as it reduces friction and wear, ensuring smooth transport. However, existing straighteners typically have several pressure rollers arranged in the transport direction, making manual lubrication cumbersome. While existing automatic lubrication systems can lubricate the surface of the pressure rollers, the spacing between each group of rollers is inconsistent, making adjustment difficult. Furthermore, impurities may remain on the roller surface, requiring removal during lubrication. Existing lubrication equipment cannot meet these operational requirements. Therefore, this invention proposes a lubrication system that can adjust the spacing of multiple groups of pressure rollers in a straightener and perform impurity removal and lubrication on each group of rollers in the transport direction. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a lubrication system for a straightening machine for titanium and titanium alloy plates and strips, which can adjust the spacing of multiple sets of pressure rollers in the straightening machine and perform impurity removal and lubrication treatment on each set of pressure rollers in the transmission direction.

[0004] The technical solution adopted in this invention is as follows: a lubrication system for a straightening machine for titanium and titanium alloy plates and strips, comprising a base, on which multiple pressing roller mechanisms are evenly arranged, each pressing roller mechanism including pressing roller one and pressing roller two, and the distance between pressing roller one and pressing roller two is adjustable; a lubrication control mechanism is slidably arranged on the base for lubricating each pressing roller; the lubrication control mechanism includes a movable frame slidably mounted on the base, a sliding seat slidably mounted on the top of the movable frame, a lubrication mounting seat slidably mounted on the sliding seat, and two lubrication frames slidably arranged on the lubrication mounting seat, each lubrication frame consisting of two symmetrical semi-circular arc components, which can be slidably connected to envelop pressing roller one and pressing roller two; a lubrication spray ring is provided at one end of the inner side of the lubrication frame for releasing lubricating oil; and a rubber scraper ring is provided at the other end of the inner side of the lubrication frame for removing impurities.

[0005] Furthermore, a collection box is provided at the bottom of the base for collecting waste oil impurities; a motor and a lead screw are provided on the top of the base, the motor driving the lead screw, and the lead screw forming a helical pair with the moving frame.

[0006] Furthermore, a control mechanism is provided on one side of the movable frame for controlling the spacing between the first and second pressing rollers on the pressing roller mechanism; the control mechanism includes a control electric cylinder fixedly mounted on the movable frame, a control plate fixedly connected to the telescopic rod of the control electric cylinder, a control motor fixedly mounted on the control plate, a mating sleeve fixedly connected to the output shaft of the control motor, a hydraulic clamping plate mounted on the mating sleeve, and a push wheel rotatably mounted at the bottom end of the control plate.

[0007] Furthermore, the pressing roller mechanism includes a mounting seat one fixedly mounted on the base, a pressing roller one rotatably mounted on the mounting seat one, a mounting seat two slidably mounted on the mounting seat one, a pressing roller two rotatably mounted on the mounting seat two, and a drive motor fixedly mounted at one end of both the mounting seat two and the mounting seat one for driving the pressing roller one and the pressing roller two.

[0008] Furthermore, a guide rod is fixedly connected to the bottom end of the second mounting base, and the guide rod is slidably connected to the first mounting base. A connecting frame is fixedly connected to the first mounting base, and an adjusting screw is rotatably mounted on the connecting frame. The adjusting screw and the second mounting base form a screw pair.

[0009] Furthermore, a mating clamping head is fixedly connected to the top of the adjusting screw. A meshing part is arranged on the circumference of the mating clamping head. A fixing mechanism is provided at the top of the connecting frame and outside the mating clamping head for clamping and fixing the mating clamping head. The mating clamping head engages with the mating sleeve and is clamped and fixed by a hydraulic clamping plate to drive the adjusting screw to rotate.

[0010] Furthermore, the fixing mechanism includes two fixing clamps slidably mounted on the top of the connecting frame. The inner side of the fixing clamps is provided with a second engagement part. A spring for providing elastic force is connected between the two fixing clamps. An arc-shaped push plate is fixedly connected to one end of the fixing clamps. The clamping head is pushed by a push wheel.

[0011] Furthermore, the lubrication control mechanism includes a second motor and a second lead screw mounted on the top of the movable frame. The second motor drives the second lead screw. The slide and the second lead screw form a helical pair. An oil cylinder is fixedly mounted on the slide and is used to control the movement of the lubrication mounting seat. Two docking electric cylinders are fixedly mounted on the lubrication mounting seat and are used to control the movement of the lubrication frame.

[0012] Furthermore, a transfer box is fixedly installed on the outside of the lubrication frame for transferring lubricating oil. The transfer box is connected to the lubrication spray ring through a transfer pipe.

[0013] The beneficial effects of this invention compared to the prior art are:

[0014] (1) At the location of each pressing roller mechanism, the distance between pressing roller one and pressing roller two is first adjusted. That is, the control plate is moved by controlling the electric cylinder to make the mating sleeve and the mating clamping head mating, and the hydraulic clamping plate clamps and fixes the mating clamping head. At the same time, the pusher pushes the arc-shaped push plate to make the fixed clamping head slide and the fixed clamping head releases the clamping and fixing of the mating clamping head. The motor is controlled to work to drive the adjusting screw to rotate, thereby making the mounting seat two slide, thereby adjusting the distance between pressing roller one and pressing roller two.

[0015] (2) Two lubrication frames can enclose the first and second pressing rollers, so that the first and second pressing rollers are located between the two lubrication frames. By moving the slide, the lubrication frames move outside the first and second pressing rollers. The rubber scraper ring can first scrape off the impurities and waste oil on the first and second pressing rollers. Then, the lubricating oil can be transferred through the transfer box. The lubrication spray ring releases the lubricating oil onto the surface of the first and second pressing rollers.

[0016] (3) In the transmission direction, the moving frame is moved to the position of each pressing roller mechanism, the distance between pressing roller one and pressing roller two is adjusted, and lubrication is completed. Attached Figure Description

Multiple pressing roller mechanisms are evenly arranged on the base 1. Each pressing roller mechanism includes a first pressing roller 8 and a second pressing roller 9, and the distance between the first pressing roller 8 and the second pressing roller 9 is adjustable. A lubrication control mechanism is slidably mounted on the base 1 for lubricating each pressing roller. The lubrication control mechanism includes a movable frame 4 slidably mounted on the base 1.

Each lubrication frame 31 consists of two symmetrical semi-circular arc-shaped components and can be slidably connected to enclose the first pressing roller 8 and the second pressing roller 9. A lubrication spray ring 35 is provided at one end of the inner side of the lubrication frame 31 for releasing lubricating oil.

The motor 2 is used to drive the lead screw 3, and the lead screw 3 and the moving frame 4 form a screw pair.

[0031] like Figure 7 and Figure 8As shown, a control mechanism is provided on one side of the movable frame 4 for controlling the spacing between the first pressing roller 8 and the second pressing roller 9 on the pressing roller mechanism; the control mechanism includes a control electric cylinder 24 fixedly mounted on the movable frame 4, a control plate 25 fixedly connected to the telescopic rod of the control electric cylinder 24, a control motor 26 fixedly mounted on the control plate 25, a mating sleeve 27 fixedly connected to the output shaft of the control motor 26, a hydraulic clamping plate 28 mounted on the mating sleeve 27, and a push wheel 29 rotatably mounted at the bottom end of the control plate 25.

[0032] like Figures 2 to 6 As shown, the pressing roller mechanism includes a mounting base 10 fixedly mounted on a base 1, a pressing roller 8 rotatably mounted on the mounting base 10, a mounting base 2 12 slidably mounted on the mounting base 10, and a pressing roller 9 rotatably mounted on the mounting base 2 12. A drive motor 13 is fixedly mounted at one end of both the mounting base 2 10 and the mounting base 10 to drive the pressing roller 8 and the pressing roller 9. A guide rod 15 is fixedly connected to the bottom end of the mounting base 2 12, and the guide rod 15 is slidably connected to the mounting base 10. A connecting frame 11 is provided, on which an adjusting screw 14 is rotatably mounted. The adjusting screw 14 and the mounting base 12 form a screw pair. A mating clamping head 16 is fixedly connected to the top of the adjusting screw 14. A meshing part 17 is arranged on the circumference of the mating clamping head 16. A fixing mechanism is provided at the top of the connecting frame 11 and outside the mating clamping head 16 for clamping and fixing the mating clamping head 16. The mating clamping head 16 is mated with a mating sleeve 27 and clamped and fixed by a hydraulic clamping plate 28 to drive the adjusting screw 14 to rotate.

[0033] The fixing mechanism includes two fixing clamps 18 that are slidably mounted on the top of the connecting frame 11. The inner side of the fixing clamp 18 is provided with a meshing part 19. A spring 21 for providing elastic force is connected between the two fixing clamps 18. An arc-shaped push plate 20 is fixedly connected to one end of the fixing clamp 18. The clamping head 16 is pushed by the push wheel 29.

[0034] like Figure 9 and Figure 10 As shown, the lubrication control mechanism includes a second motor 5 and a second lead screw 6 mounted on the top of the movable frame 4. The second motor 5 drives the second lead screw 6. The slide 22 and the second lead screw 6 form a helical pair. An oil cylinder 23 is fixedly mounted on the slide 22 and is used to control the movement of the lubrication mounting base 30. Two docking electric cylinders 33 are fixedly mounted on the lubrication mounting base 30 and are used to control the movement of the lubrication frame 31. A transmission box 32 is fixedly mounted on the outside of the lubrication frame 31 for transmitting lubricating oil. The transmission box 32 is connected to the lubrication spray ring 35 through a transmission pipe.

[0035] Operating principle: During lubrication, motor 2 drives screw 3 to rotate, causing the moving frame 4 to move. At the location of each pressing roller mechanism, the distance between pressing roller 8 and pressing roller 9 is first adjusted. This is achieved by controlling the control plate 25 to move via electric cylinder 24, so that the mating sleeve 27 engages with the mating clamping head 16, and the hydraulic clamping plate 28 clamps and fixes the mating clamping head 16. Simultaneously, push wheel 29 pushes arc-shaped push plate 20, causing the fixed clamping head 18 to slide, thus releasing the clamping head 16. Motor 26 is then activated to drive adjusting screw 14 to rotate, thereby causing mounting base 12 to slide, thus adjusting the distance between pressing roller 8 and pressing roller 9.

[0036] Furthermore, the second motor 5 drives the second lead screw 6 to rotate, causing the slide block 22 to slide. The hydraulic cylinder 23 controls the height of the lubrication mounting base 30, so that the two lubrication frames 31 are respectively located outside the first pressure roller 8 and the second pressure roller 9. At this time, the distance between the first pressure roller 8 and the second pressure roller 9 is the same as the distance formed by the two symmetrical semi-circular arc components on the lubrication frame 31. Therefore, the docking cylinder 33 controls the movement of the lubrication frame 31, and the two lubrication frames 31 can envelop the first pressure roller 8 and the second pressure roller 9, so that the first pressure roller 8 and the second pressure roller 9 are located between the two lubrication frames 31. As the slide block 22 moves, the lubrication frame 31 moves outside the first pressing roller 8 and the second pressing roller 9. The rubber scraper ring 34 can first scrape off the impurities and waste oil on the first pressing roller 8 and the second pressing roller 9. Then, the lubricating oil can be transferred through the transfer box 32. The lubrication spray ring 35 releases lubricating oil onto the surface of the first pressing roller 8 and the second pressing roller 9. Combined with the rotation of the first pressing roller 8 and the second pressing roller 9, the lubrication treatment of all areas is completed. In the transmission direction, the moving frame 4 moves to the position of each pressing roller mechanism, adjusts the spacing of the first pressing roller 8 and the second pressing roller 9, and completes the lubrication treatment.
