Description

Technical Field

[0001] The invention relates to the technical field of rod grinding, in particular to a cylindrical end grinding device and a grinding process for machining a slag stop rod. Background Art

[0002] The slag stopper is a tool used in metallurgical processes. It is mainly used to stop the slag during steel tapping and prevent it from entering the ladle, thereby improving the purity and quality of molten steel. When the cylindrical end of the slag stop rod is ground, the rod is driven to rotate at high speed through a driving mechanism at one end of the grinding machine, and then the driving mechanism at the other end of the machine controls the low-speed rotating grinding tool to contact the end of the rod to achieve the grinding of the end of the rod. The disadvantage is that the grinding tool will heat up rapidly during grinding. Multiple grinding tools can be used in turn to avoid the wear caused by overheating of a single grinding tool. When a single grinding tool is grinding, other grinding tools get sufficient rest and cool down; in addition, waste chips are retained in the sand grain grooves on the surface of the grinding tool, and a wire brush can be used to clean the surface of the grinding tool. If the rotating wire brush cleans the overheated grinding tool, it may be deformed or damaged due to the high temperature, and the bristles may be softened or burnt due to the high temperature, resulting in poor cleaning effect and even damage to the surface of the grinding tool. In order to protect the grinding tool and ensure its normal operation, the grinding tool can be cleaned after it has cooled down. Based on the above needs and problem solving, the present invention provides a grinding device and a grinding process for the cylindrical end of a slag stop rod. Summary of the invention

One end of the spur rack 47 presses on the outer edge of the disc frame 27.

[0066] A grinding process for a cylindrical end of a slag stopper rod comprises the following steps:

[0067] Step 1: A driving mechanism at one end of the grinding machine controls the rod 3 to rotate at a high speed, and a driving mechanism at the other end of the grinding machine controls the integrated regulator 1 to move to drive the ring-mounted grinder 2 to translate. When the rod 3 is relatively inserted into the middle position between the multiple ring-mounted grinders 2, the grinder 2 and the rod 3 maintain the same spatial position;

[0068] Step 2: The plurality of grinding rod groups 6 arranged in a circle contact and grind the side wall of the end of the rod 3 in turn, and the grinding advancement depth of the next grinding rod group 6 grinding the side wall of the rod 3 is increased compared with the grinding advancement depth of the previous grinding rod group 6;

[0069] Step three: when a single sanding rod group 6 contacts the end side wall of the sanding rod 3, the remaining sanding rod groups 6 rest and cool down, and the next sanding rod group 6 to be sanded is cleaned by the brush roller group 7, and when the next sanding rod group 6 starts to sand the side wall of the rod 3, the cleaning of the sanding rod group 6 by the brush roller group 7 is automatically finished.

[0070] The main shaft 9 is externally connected to the motor drive mechanism in the prior art. The main shaft 9 rotates slowly to drive the single pendulum 10 to swing, and then the dial control prism 22 pushes the arc plate rack 16 encountered. The arc plate rack 16 moves to drive the unit shaft 30 to rotate, and then the feed screw 31 rotates to cause the F-type frame 32 to move. The F-type frame 32 drives the rod shaft 41, and then the grinding rod 42 approaches the outer wall of the rod 3 to grind the outer wall of the end of the rod 3. The specific principle is that the high-speed rotating rod 3 and the low-speed rotating grinding rod 42 are in contact to achieve grinding. The power source of the grinding rod 42 is also the main shaft 9. The main shaft 9 drives the cushion arc column 28 and the outer gear ring 26 to rotate synchronously. The outer gear ring 26 drives the drive shaft 37, and then the transposition shaft 39 is driven by the fixed shaft 38. Next, the rod shaft 41 and the grinding rod 42 rotate synchronously at a low speed.

[0071] When the sanding rod 42 contacts the polishing rod 3, the single pendulum 10 continues to swing, and the arc plate rack 16 continues to move. The subsequent rotation causes the sanding rod 42 to gradually approach the axis of the rod 3. This is a small displacement, that is, when the sanding rod 42 polishes the rod 3, the sanding rod 42 gradually grinds deeper, but the sanding rod 42 overheats and needs to rest and cool down. Therefore, the single pendulum 10 continues to swing and encounters the return column 17. The return column 17 causes the dial control prism 22 to move by turning the pull-back column 25. The end of the dial control prism 22 is separated from the arc plate rack 16, so that the arc plate rack 16 loses the driving pressure. The return spring 29 presses the unit shaft 30 to reverse and reset, corresponding to the subsequent sanding rod 42 and the rod 3. The overheated sanding rod 42 rests and cools down, and the single pendulum 10 continues to swing and encounters the next arc plate rack 16, starting the next drive, so that the next sanding rod 42 starts to polish the rod 3.

[0072] When the main shaft 9 rotates slowly, it will also transmit the power to the pressure worm 20, and then the neck shaft 21 will rotate slowly to drive the slow adjustment ring cylinder 18 to swing slightly, and the slow adjustment ring cylinder 18 will drive all the homing columns 17 to swing slightly, that is to say, the next grinding rod 42 will grind the rod 3 more deeply. If the next grinding rod 42 and the previous resting grinding rod 42 penetrate into the rod 3 to the same extent, the next grinding rod 42 will not contact the grinding rod 3. Therefore, if the next grinding rod 42 wants to get closer to the axis of the rod 3, the timing of resetting the grinding rod 42 needs to be delayed. The control source of resetting is the homing column 17, refer to Figure 7The more the return column 17 moves to the right, the greater the distance that the dial control prism 22 pushes the arc plate rack 16 to travel, and the corresponding grinding rod 42 can penetrate deeper into the rod 3. Therefore, the single pendulum 10 pushes the arc plate rack 16 encountered in turn, and the multiple return columns 17 arranged in the ring swing slowly. In this way, the time from the initial displacement to the reset of the multiple arc plate racks 16 arranged in the ring becomes longer and longer, so that the next grinding rod 42 can grind deeper into the rod 3 than the previous grinding rod 42.

[0073] When the previous sanding rod 42 is sanding the rod 3, the next sanding rod 42 to be prepared is cleaned by the rotation of the metal brush roller 35. The principle is that the rotation of the disc frame 27 drives the pad arc column 28, and the pad arc column 28 will push the contacting spur rack 47, and then the spur rack 47 moves to control the rotation of the horizontal axis 48, and then the brush frame 36 moves to drive the long secondary shaft 45, controlling the metal brush roller 35 to approach and contact the sanding rod 42, and the transposition cylinder gear 40 always drives the secondary gear 44, and then drives the long secondary shaft 45 through the short secondary shaft 43, causing the metal brush roller 35 to rotate, and the rotating metal brush roller 35 contacts the counter-rotating sanding rod 42 to clean the surface of the sanding rod 42, and after the pad arc column 28 and the contacting spur rack 47 are separated, the metal brush roller 35 moves and separates from the sanding rod 42, and the cleaning work is automatically completed, and the cleaned sanding rod 42 is put into the sanding work.

[0074] Combination Figure 3 and Figure 7 It is understood that the single pendulum 10 rotates clockwise for multiple circles, and the arc plate racks 16 encountered will be moved one by one, and the distance of advancement of different arc plate racks 16 becomes larger and larger, corresponding to the gradual increase in the depth of the polished rod 3. After the polishing of the rod 3 is completed, the motor drive mechanism drives the spindle 9 in the reverse direction. The purpose of the reverse reset of the spindle 9 is to reverse and reset the corresponding offset ring 14. In addition, the single pendulum 10 is reset by rotating counterclockwise for multiple circles. Here, the single pendulum 10 is successfully reset because Figure 7 The end of the dial control prism 22 is designed with an inclined surface. When the dial control prism 22 swings to the left, it encounters a protrusion on the arc plate rack 16. The protrusion of the arc plate rack 16 drives the dial control prism 22. The dial control prism 22 moves downward to be smoothly dislocated and separated from the protrusion of the arc plate rack 16.
