Description

Technical Field

[0001] The invention belongs to the technical field of plate and strip production, and in particular relates to an oxide scale cleaning device for the side edge of a plate and strip. Background Art

[0002] The basic production process of alloy hot-rolled strips is: first, alloy ingots are obtained through smelting and forging, and then the alloy ingots are heated and rolled to obtain hot-rolled strips. The hot-rolled strips formed by high-temperature heating and rolling have an oxide layer on the surface due to oxidation. If this oxide layer is not cleaned, it will be pressed into the surface of the strip during the subsequent cold rolling, affecting the quality of the cold-rolled strip.

[0003] Existing cleaning methods for oxide scale on plates and strips are mostly carried out by mechanical grinding to clean the upper and lower surfaces of the plates and strips. For example, Chinese invention CN200910172345.4 discloses a new process for online removal of oxide scale on the surface of hot-rolled copper plates and strips. The oxide scale on the upper or lower surface of the rolled piece is scraped off by a scraping brush roller to scrape off the oxide scale that has been loosened due to hot rolling to prevent it from being pressed into the rolled piece during the next rolling process.

[0004] However, the above technical solution can only clean the oxide scale on the upper and lower surfaces of the plate and strip, while in actual production, there is also oxide scale or rust on the two sides of the plate and strip. The existing equipment is inconvenient to clean the sides of the plate and strip. If it is not cleaned, it will also affect the subsequent processing and production quality of the plate and strip. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] Embodiment 1

[0031] See also Figure 1 and 2 As shown, the present invention is an oxide scale cleaning device for the side of a plate strip, comprising two symmetrically arranged frames 1, the two frames 1 being respectively located on both sides of the plate strip. The frames 1 are connected to a mounting plate 101, and the mounting plate 101 is rotatably connected to two horizontally arranged transmission shafts 2 and two vertically arranged rotation shafts 3 through a bearing bracket.

[0032] The transmission shaft 2 is fixedly connected with a driving wheel 201 , and the rotating shaft 3 is connected with a driven wheel 301 meshing with the driving wheel 201 . The driving wheel 201 and the driven wheel 301 are mutually meshing bevel gears, so that the rotating shaft 3 can be vertically arranged relative to the transmission shaft 2 .

[0033] The two transmission shafts 2 are connected to a power device 4 via a transmission mechanism, which is used to drive the two transmission shafts 2 to rotate synchronously through the power device 4 and drive the rotating shaft 3 to rotate through the transmission shaft 2.

[0034] Among them, Figure 3As shown, a brush roller 302 is fixedly connected to the upper end of the rotating shaft 3. The rotating shaft 3 can be connected to the rotating shaft of the brush roller 302 through a coupling to achieve the installation of the brush roller 302. The two transmission shafts 2 respectively drive the two rotating shafts 3 to rotate, and then the brush roller 302 rotates. The rotation of the brush roller 302 is used to grind and clean the oxide scale or rust on the side of the plate and strip.

[0035] Among them, the brush rollers 302 connected to the two rotating shafts 3 on the same mounting plate 101 rotate in opposite directions, and are used to perform rotational cleaning of the same side of the plate strip in different directions through the two brush rollers 302. The oxide scale on the side of the plate strip has different directions of peeling and warping, which is similar to the effect of smooth hair and reverse hair. Therefore, when the brush roller 302 rotates to clean the side of the plate strip, it is in the smooth direction of the oxide scale, which is not conducive to the brush roller 302 to remove the oxide scale on the side of the plate strip. At this time, since the other brush roller 302 rotates in the opposite direction, it is in the reverse direction when cleaning the oxide scale that has not been cleaned, so that it is easy to clean the oxide scale from the side of the plate strip, so that the overall cleaning effect and cleaning efficiency are greatly improved.

[0036] At the same time, if Figure 3 and 4 As shown, the transmission shaft 2 is fixedly connected with the cam 202. The mounting frame 102 is fixedly connected to the upper surface of the mounting plate 101 by welding or screw connection, and the mounting frame 102 is rotatably connected to the spline sleeve 103 through a bearing, and the driven wheel 301 is fixedly connected to the outer wall of the spline sleeve 103, so that the transmission shaft 2 drives the spline sleeve 103 to rotate through the driving wheel 201.

[0037] The lower end of the rotating shaft 3 is welded or connected through a coupling with a spline shaft 303 that cooperates with the spline sleeve 103, and the lower end of the spline shaft 303 passes through the spline sleeve 103 and cooperates with the cam 202, so that the rotating shaft 3 can reciprocate axially through the rotation of the cam 202, so that the rotating shaft 3 can drive the brush roller 302 to rotate in a circular manner while also driving the brush roller 302 to reciprocate up and down along the axial direction, thereby producing an up and down grinding and scraping effect on the oxide scale of the side plate of the plate and strip, further improving the cleaning effect on the side of the plate and strip.

[0038] Among them, the lower end of the spline shaft 303 is rotatably connected to the roller seat 104 through the bearing seat, and is rotatably connected to the roller 105 through the roller seat 104. An annular groove 106 is opened on the circumference of the roller 105, which is used to cooperate with the working surface of the cam 202 through the annular groove 106, so that the width of the annular groove 106 is adapted to the rearward degree of the cam 202, and the inner side surface of the annular groove 106 and the side surface of the cam 202 are used to limit the circumferential rotation of the roller seat 104, thereby ensuring that the axial direction of the roller 105 remains parallel to the axial direction of the cam 202, which is beneficial to improving the stability of the mutual action between the cam 202 and the roller 105.

[0039] At the same time, the cams 202 on the two transmission shafts 2 connected to the same mounting plate 101 are offset by 180° in the circumferential direction, that is, the two brush rollers 302 located on the same side of the plate belt maintain one axial upward movement and the other axial downward movement at the same time, so that the overall movement is relatively balanced, which is beneficial to maintaining relative stability of the frame 1.

[0040] Embodiment 2

[0041] On the basis of implementation one, Figure 5 As shown, the mounting plate 101 is welded or screwed with vertical plates 107 corresponding to the rotating shafts 3 one by one, and the vertical plates 107 are welded or bolted with flat plates 108 on their sides; the flat plates 108 are provided with through holes corresponding to the positions of the rotating shafts 3.

[0042] Two guide rods 109 are welded or threadedly connected to the upper surface of each flat plate 108, and a pressure plate 110 is movably inserted through the two guide rods 109; a spring 111 is sleeved on the guide rod 109, and a limit block is welded or threadedly connected to the upper end of the guide rod 109, the upper end of the spring 111 abuts against the limit block, and the lower end of the spring 111 abuts against the upper surface of the pressure plate 110, so that the pressure plate 110 remains in a downward pressed state under the action of the spring 111.

[0043] The rotating shaft at the upper end of the brush roller 302 is connected to the vertical shaft 304 through a coupling, and the upper end of the vertical shaft 304 passes through the through hole and is rotatably connected to the pressure plate 110 through a bearing seat. The spring 111 is used to press the pressure plate 110 downward, so that the vertical shaft 304 presses the brush roller 302 downward, and then the roller 105 connected to the lower end of the spline shaft 303 maintains contact with the working surface of the cam 202, thereby improving the stability and reliability of the cooperation between the roller 105 and the cam 202.

[0044] Embodiment 3

[0045] Based on the second embodiment, Figure 1 and 2 As shown, the mounting plate 101 is horizontally slidably connected to the frame 1 through a slider guide mechanism, so that the mounting plate 101 can move horizontally. The frame 1 is threadedly connected with a screw rod 112, and one end of the screw rod 112 is connected to the vertical plate 107, and the other end of the screw rod 112 is connected to a hand wheel. By rotating the screw rod 112, the vertical plate 107 is pushed or pulled by the screw rod 112 to adjust the horizontal position of the mounting plate 101.

[0046] At the same time, a cross transmission box 113 is fixedly connected to the upper surface of the mounting plate 101, and the two transmission shafts 2 are respectively connected to the two output shafts of the cross transmission box 113, and the input shaft of the cross transmission box 113 is connected to the power device 4, so that the two transmission shafts 2 are synchronously driven to rotate by one power device 4.

[0047] Furthermore, the input shaft of the cross transmission box 113 is fixedly connected with the first spline sleeve 401 by interference fit or through a coupling. The output shaft of the power device 4 is fixedly connected with the first spline shaft 402 matched with the first spline sleeve 401 .

[0048] Specifically, the power device 4 includes a T-shaped transmission box 403 and a motor 404 connected to the T-shaped transmission box 403. The T-shaped transmission box 403 and the motor 404 are connected to the frame 1 through a mounting frame, or are fixed to the ground separately.

[0049] The two output shafts of the T-shaped transmission box 403 are respectively connected to the first spline shaft 402 matched with the first spline sleeve 401 connected to the mounting plates 101 on the two frames 1.

[0050] That is, the cross transmission boxes 113 on the two mounting plates 101 are synchronously driven by a power device 4, and the cross transmission box 113 drives two transmission shafts 2 on the same mounting plate 101, so that four brush rollers 302 are driven to rotate simultaneously by a motor 404.

[0051] When cleaning the side edges of strips of different widths, the brush roller 302 can be moved to a position for cleaning the side edges of the strips by rotating the screw rod 112 to adjust the position of the mounting plates 101 on both sides of the strips.

[0052] During the movement of the mounting plate 101, the first spline sleeve 401 connected to the input shaft of the cross transmission box 113 produces axial movement relative to the first spline shaft 402 connected to the output shaft of the T-type transmission box 403, and the first spline sleeve 401 and the first spline shaft 402 always maintain cooperation, so that when the mounting plate 101 moves, the cross transmission box 113 and the power device 4 can automatically adapt to the position adjustment changes.

[0053] At the same time, when the brush roller 302 is worn and its cleaning ability on the side of the plate strip is reduced, the position of the mounting plate 101 can be adjusted to reduce the distance between the brush roller 302 and the side of the plate strip, thereby increasing the force of the brush roller 302 on the side of the plate strip, thereby improving the cleaning effect of the brush roller 302 and avoiding the situation where the brush roller 302 cannot be used after being worn and needs to be replaced. Therefore, by adjusting the position of the mounting plate 101, the utilization rate of the brush roller 302 can be improved, which is beneficial to reducing the overall production cost.
