Description

Technical Field

[0001] The utility model relates to the technical field of grinding roller surfacing equipment, in particular to a novel automatic slag cleaning device for grinding roller surfacing. Background Art

[0002] The cement production process involves roasting raw materials into clinker, which is then ground into cement. Blast furnace slag is widely used as an admixture in the cement production process. Raw materials and slag are ground in raw and slag vertical mills, which are key pieces of equipment. As raw materials are crushed between the grinding surfaces of the grinding discs and rollers in the vertical mill, the grinding surfaces continuously wear, reducing the effective grinding area. This reduces the mill's grinding efficiency and increases power consumption. A 10% drop in efficiency can lead to production quotas being missed, resulting in annual power losses exceeding millions of yuan. Uneven wear of the grinding surfaces can even cause the grinding discs and rollers to collide, causing the mill to vibrate excessively and shut down, disrupting cement production. Therefore, it is crucial to replace or repair rollers that have reached a certain level of wear with a hardfacing weld.

[0003] Replacing or repairing the rollers of a vertical mill requires long, high-temperature hardfacing operations. During this process, flux-cored wire welding is used in a multi-layer, multi-pass, open-arc welding process. The slag produced by the flux-cored wire is primarily composed of oxides, sulfides, and nitrides. These components protect the weld, prevent oxidation, and ensure good weld quality. During hardfacing, especially during the "base" welding process, a large amount of slag and spatter is generated. This slag and spatter are typically cleaned manually, layer by layer. If not cleaned promptly, these debris can mix into the weld layer, causing slag inclusions and seriously affecting the weld quality. Furthermore, the large size of the rollers and the typically circular weld area make manual cleaning inconvenient, time-consuming, and ineffective, significantly impacting production efficiency and the quality of the roller hardfacing. Furthermore, the hardfacing process produces a large amount of toxic and harmful high-temperature fumes, and the removal of slag also produces a significant amount of dust, which can seriously affect the health of operators.

[0004] At present, the slag cleaning equipment used in grinding roller hardfacing uses a motor to control the rotation of the cleaning wheel at the front end during the cleaning process, and the welding slag on the grinding roller is cleaned during the rotation. In specific operations, the cleaning wheel needs to be moved to the annular welding area of ​​the grinding roller, and the cleaning wheel cleans the welding slag and spatter on the grinding roller during the welding process. During the cleaning process, the slag cleaning equipment needs to move its position in time with the weld bead, and the height of the cleaning wheel of the slag cleaning equipment needs to be adjusted according to the height of the weld bead. Especially in the use of automated hardfacing equipment, the cleaning wheel of the existing slag cleaning equipment cannot match the hardfacing program to move its position in time with the weld bead, which makes it more troublesome to use. In addition, the cleaning wheel relies on the weight of the slag cleaning equipment itself to apply pressure on the surface of the grinding roller. The necessary shock-absorbing measures are lacking, which will inevitably cause the grinding roller to vibrate during the hardfacing process, affecting the straightness of the weld layer. Summary of the Invention

[0024] The beneficial effects of the utility model are:

[0025] The frame fixing plate of the utility model is fixed to the welding gun cross arm by bolts, and the welding gun is located on the welding gun cross arm, and the welding gun cross arm is arranged on the XZ two-axis electric slide. When the welding gun cross arm moves on the XZ two-axis, it will drive the automatic slag cleaning device of the utility model and the welding gun to move together, and the automatic slag cleaning device is located behind the welding gun; the automatic slag cleaning device is synchronized with the left and right movement of the welding gun, that is, the weld bead (X direction, also known as the weld bead width direction), and can move the position in time with the weld bead.

[0037] The present invention will be further described below with reference to the accompanying drawings:

[0038] See also Figure 1 、 Figure 2 、 Figure 3 As shown, a novel automatic slag cleaning device for grinding roller surfacing welding comprises a track device 3, a connecting rod device 4, a reversing device 5, an adjusting device 6, a cleaning device 7 and the like. The track device 3 is fixed with bolts to the frame fixing plate 2, and the frame fixing plate 2 is fixed to the welding gun cross arm by bolt connection, and is synchronized with the left and right movement of the welding gun, i.e., the weld bead (X direction, i.e., the direction of the weld bead width). The welding gun cross arm realizes linkage control by connecting to an automated program to match welding parameters. The welding parameters include welding voltage, wire feed speed, rotation speed, weld bead height, weld bead width, etc., wherein the weld bead height, i.e., the Z-direction movement, is controlled by the lifting and lowering movement of the welding gun cross arm to realize automatic adjustment of the height of each layer of weld bead, and the weld bead width, i.e., the X-direction movement, is controlled by the left and right movement of the welding gun cross arm to realize step spacing adjustment of each circle of weld bead, and the automatic slag cleaning device is installed on the welding gun cross arm at the same time as the welding gun, as shown in FIG. Figure 2 As shown, the grinding direction is synchronized with the weld direction (X direction). On the one hand, the welding follow-up of the weld in the X direction and Z direction can be achieved by lifting and lowering the cross arm and moving it left and right. On the other hand, the slag cleaning device is automatically adjusted to the cleaning point on the weld surface in the circumferential direction of the grinding roller 1 through the track device 3 in the Y direction. The connecting rod device 4 is used to apply the cleaning force, the reversing device 5 is used to adjust the cleaning angle, and the regulating device 6 is used to adjust the cleaning height to offset the reaction force. The cleaning device 7 acts on the weld surface of the grinding roller 1 to grind the welding slag and spatter generated during the surfacing process. Figure 2 The figure is a schematic diagram of the direction of movement of the cleaning device 7. The grinding roller 1 can realize automatic rotation, and the rotation direction W is as follows: Figure 2As shown, in actual welding, the grinding roller 1 rotates along the rotation direction W all the time. One rotation of the grinding roller 1 means one pass of welding by the welding gun. The welding gun cross arm can only realize left and right movement in the X-axis direction and up and down movement in the Z-axis direction, thereby driving the welding gun to realize left and right movement in the X-axis direction and up and down movement in the Z-axis direction. The welding direction is fixed. Assuming it is from left to right, the process is: first weld the first pass of the first layer. After the first pass is welded, the welding gun cross arm is driven by the X-axis electric slide, and then the welding gun is driven to move a certain distance to the right along the X-axis direction (the program sets the welding width, and each welding is completed for one circle). It can be moved a certain distance to the right along the X-axis direction). Assuming that a total of 10 passes are required, 10 passes are equal to 10 laps. After 10 laps of welding, the first layer of cladding is obtained. Then the welding gun moves leftward and upward back to the top of the first pass (starting position) of the first layer of cladding, that is, the second layer. The first pass of the second layer starts to be welded to the right, and so on. After welding each layer, it must return to the top of the starting point. What changes is that the Z-axis electric slide drives the welding gun cross arm and then drives the welding gun to lift up in the Z direction. During the entire moving process, the new automatic slag cleaning device for grinding roller cladding of this embodiment is cleaned together.

When the drive motor 3.14 is activated, it rotates the lead screw 3.5, causing the lead screw nut 3.6 to move linearly along the lead screw 3.5.

Before use, the length of the basket bolt 6.1 should be reasonably adjusted so that the brush head can clean the surface to be welded without excessive wear of the brush head or excessive pressing force causing the brush head to bounce off the surface to be welded.

[0045] The utility model discloses an automatic slag cleaning device which can replace manual slag cleaning and can realize the requirements of grinding roller welding process for thorough slag cleaning, dust cleaning and spatter cleaning. The device has a simple structure, efficient and effective slag cleaning and improves the grinding roller surfacing welding quality.

[0046] Before welding, the present invention can automatically adjust the cleaning point of the cleaning brush head 7.4 on the weld surface in the circumferential direction of the grinding roller through the Y-axis track device 3 in its own structure. The cleaning point needs to be located a little further away from the welding gun, and cleaning should be done after welding. Before welding, the length of the basket bolt 6.1 should also be reasonably adjusted to adjust the height of the cleaning brush head 7.4. This allows the cleaning brush head 7.4 to clean the surface to be welded without excessive wear or excessive pressure causing the brush head to bounce off the surface to be welded. Before welding, the angle of the cleaning brush head 7.4 should also be adjusted using the reversing device 5. After adjustment, the cleaning brush head 7.4 begins to move with the welding gun, and the cleaning device 7 cleans the welding gun after welding. During cleaning, the slag cleaning motor 7.1 is started, and the slag cleaning motor 7.1 drives the cleaning brush head 7.4 to rotate via the cleaning connecting rod 7.3 to achieve cleaning. Both the drive motor 3.14 and the slag cleaning motor 7.1 are connected to a power supply and a control system, thereby achieving automated operation.
