Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to an electrode grinding device. Background Art

[0002] During the electroslag remelting process, the presence of non-metallic inclusions seriously affects the mechanical properties of steel, such as strength and ductility. Extensive experience has demonstrated a direct correlation between oxide inclusions and oxygen content in steel. Oxidation and reduction are two aspects of a chemical reaction: when one element is oxidized, another is inevitably reduced. During the remelting process, reactive elements in steel, such as Al, Ti, Mg, and B, are often lost due to oxidation. The iron oxide scale formed on the electrode surface is one of the pathways by which impurities enter the slag and molten steel during the electroslag remelting process. Therefore, for high-quality consumable electrodes, the oxide scale on the outer circumference of the electrode must be polished and removed.

[0003] Currently, mainstream methods for removing oxide scale include surface shot blasting and surface grinding. Shot blasting can easily leave residual impurities, such as carbon, on the electrode surface, preventing it from meeting high-quality requirements. Surface grinding primarily relies on manual grinding using simple grinding tools or using a peeling machine. The former is labor-intensive and time-consuming, resulting in low efficiency, while the latter is costly. Utility Model Content

[0029] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0030] like Figure 1 and 3 A device for grinding an electroslag remelting consumable electrode includes a rolling support device. The rolling support device is mounted on a base, supporting the electrode being ground and driving the electrode to rotate about its axis. In this embodiment, the base is the ground. The axial direction of the electrode placed on the rolling support device is aligned with the front-to-back direction.

[0031] Furthermore, the rolling support device includes a driving roller frame 1 and a driven roller frame 14. Each of the driving roller frame 1 and the driven roller frame 14 comprises a body, a rotating bracket, and rollers. Each roller frame includes two symmetrically arranged rotating brackets, which are mounted on the corresponding body via a rotating connection, and the rollers are mounted on the corresponding rotating brackets via a rotating connection. When electrodes of different diameters are placed on the rolling support device, the rotating brackets automatically rotate to adapt to the electrodes, so that the rollers on them come into contact with the electrodes.

[0032] The rotating bracket is mounted with a rotary drive motor 1-1, which is connected to the rollers on the driving roller frame 1 via an intermediate gear. This drives the electrode, which is in contact with the rollers, to rotate about its own axis. Typically, the axis of the rotary drive motor 1-1 coincides with the axis of rotation of the rotating bracket. The rollers on the driven roller frame 14 serve only as support, passively rotating under the drive of the electrodes.

[0033] Furthermore, the main body of the active roller frame 1 is fixed relative to the base, which is convenient for connecting the cable of the rotary drive motor 1-1, while the driven roller frame 14 is movable. Figure 3 and 4 The bottom of the main body is equipped with a track wheel, which cooperates with the first guide rail 11 installed on the ground. The track wheel is also provided with a locking mechanism, such as a locking screw at the end for contacting the track wheel. Before placing the electrode, the driven roller frame 14 can be moved according to the length of the electrode, and then the locking screw is tightened to fix the driven roller frame 14. Furthermore, a first limit device 12 is installed at the end of the first guide rail 11 away from the active roller frame 1 to prevent the driven roller frame 14 from leaving the first guide rail 11.

[0034] like Figure 1 and 2 The grinding device also includes a support frame 10, a moving device 5 that can move back and forth on the top of the support frame 10, and a support beam 3 installed on the moving device 5 in the middle by a rotation connection.

[0035] The support frame 10 includes a plurality of columns and longitudinal beams mounted on top of the columns. Figure 2 Second guide rails 9 (guide rail plates) running forward and backward are installed on the left and right sides of the longitudinal beam. The moving device 5 includes a moving body 5-1, mounted with rolling wheels 5-4. These rolling wheels 5-4 cooperate with the second guide rails 9 to guide movement. To prevent the moving body 5-1 from tipping over, three sets of rolling wheels 5-4 are provided on each side of the guide rail plate. These three sets of rolling wheels 5-4 contact the top, bottom, and outer surfaces of the guide rail plate, respectively. Second stoppers 13 are also provided at the front and rear ends of the second guide rail 9.

[0036] The moving device 5 also includes a moving drive motor 5-5 mounted on the moving body 5-1, a drive gear 5-2 connected to the output shaft of the moving drive motor 5-5 via a speed reducer, and a rack 5-3 fixed relative to the second guide rail 9. The drive gear 5-2 and the rack 5-3 are meshed. The moving drive motor 5-5 drives the drive gear 5-2 to rotate, thereby enabling the moving device 5 to move along the longitudinal beam.

[0037] like Figure 1 A grinding wheel 2 is mounted on one end of the support beam 3 near the rolling support device. A grinding drive motor 15 is also mounted on the support beam 3. The grinding drive motor 15 is connected to the grinding wheel 2 via a transmission belt 16, driving the grinding wheel 2 to rotate at high speed. A protective shield is also provided on the outside of the grinding wheel 2 and the transmission belt 16 to prevent flying chips.

[0038] The other end of the support beam 3 is provided with a counterweight device 4. The counterweight device 4 is a plurality of stacked counterweight blocks fixed to the support beam 3 by screws, and the number of the counterweight blocks can be adjusted according to the situation.

[0039] Furthermore, a height adjustment mechanism connected to the other end of the support beam 3 is also installed on the moving device 5 , and the height adjustment mechanism is used to pull the support beam 3 to rotate to change the height of the grinding wheel 2 .

[0040] In this embodiment, the height adjustment mechanism includes a roller mounted on a mobile device 5 and a steel wire rope 6 wound around the roller, and the protruding end of the steel wire rope 6 is connected to the other end of the support beam 3. The center of gravity of the entire support beam 3 and the device thereon is located on the left side of the rotation connection position, so that the steel wire rope 6 remains in a taut state. The height adjustment mechanism also includes a handwheel 7 and a reducer 8, the handwheel 7 is connected to the input end of the reducer 8, and the roller is connected to the output end of the reducer 8. The reducer in this embodiment adopts a worm gear structure, which has a self-locking characteristic. After the handwheel 7 is released, the support beam 3 can still remain stationary. When the handwheel 7 is rotated to retract and release the steel wire rope 6, the support beam 3 rotates accordingly, thereby achieving the purpose of adjusting the height of the grinding wheel 2.

[0041] The height adjustment mechanism may also adopt other structural forms, such as an electric push rod or a manual telescopic rod whose two ends are respectively rotatably connected to the moving body 5-1 and the support beam 3.

[0042] During grinding, first adjust the position of the driven roller frame 14 according to the length of the electrode, lock the track wheel at the bottom of the driven roller frame 14, then place the electrode on the rolling support device, and then move the moving device 5 to one end of the electrode, and then start the grinding drive motor 15, and lower the grinding wheel 2 through the handwheel 7 so that it can just grind off the oxide layer, and then start the rotary drive motor 1-1 and the moving drive motor 5-5. While the electrode rotates, the high-speed rotating grinding wheel 2 moves to the other end of the electrode driven by the moving device 5, and finally completes the grinding of the entire outer cylindrical surface.

[0043] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
