Description

Technical Field

[0001] This utility model relates to an auxiliary device for processing copper tubes in crystallizers, and in particular, to a scribing device for slotting copper tubes in crystallizers. Background Technology

[0002] The crystallizer copper tube is a core component of continuous casting equipment. During continuous casting, molten steel flows from the upper end to the lower end of the crystallizer copper tube. After passing through the crystallizer copper tube, the molten steel forms a billet with a solidified outer shell and an unsolidified molten steel inside. The performance of the crystallizer copper tube directly affects the continuous casting speed, and for the crystallizer copper tube, cooling performance is one of the most important properties.

[0003] Crystallizer copper tubes are divided into straight tubes and curved tubes. Curved tubes are easier to achieve high drawing speeds than straight tubes, which in turn requires high cooling performance. The most common cooling method for crystallizer copper tubes is to groove the outer surface of the tube and then install a water jacket on the outside of the tube, so that the grooves form water channels for cooling water to flow through. Before grooving, lines need to be pre-marked on the outer surface of the copper tube to facilitate the grooving process. To improve the consistency of heat dissipation along the extension direction of the copper tube, the curvature of the marked lines must match the curvature of the copper tube. The traditional marking method uses a template, that is, a fan-shaped template with the same curvature as the copper tube is placed on the surface of the copper tube, and then lines are marked along the curved boundary of the template on the surface of the copper tube. This method requires that the center of the template be concentric with the center of the copper tube when it is placed, which is relatively cumbersome. Meanwhile, when the crystallizer copper tube has errors within the allowable range after processing, that is, when the crystallizer copper tube is bent, it is not a standard arc. In this case, if the line is drawn by using a pre-prepared standard template, the drawn arc will inevitably not be consistent with the bending range of the crystallizer copper tube, thus affecting the accuracy of the line drawing and reducing the product quality after subsequent grooving. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the prior art, the scribing method of the copper tube of the crystallizer is cumbersome and the scribing cannot be consistent with the bending range of the copper tube of the crystallizer. In view of this, this utility model provides a scribing device for slotting copper tubes of crystallizer that is easy to operate, simple to operate and has high scribing accuracy.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a marking device for slotting copper tubes in a crystallizer, including a connecting plate, with fixed ends at both ends of the connecting plate for fixing to the ends of the copper tubes in the crystallizer, a slider slidably provided on the connecting plate, a telescopic rod slidably provided on the slider, the sliding direction of the telescopic rod relative to the slider being perpendicular to the sliding direction of the slider relative to the connecting plate, the side of the telescopic rod away from the slider abutting against the arc-shaped surface of the copper tube in the crystallizer, a connecting post slidably provided on the telescopic rod, the sliding direction of the connecting post being consistent with the telescopic direction of the telescopic rod, and a marker pen for marking lines on the side plane of the copper tube in the crystallizer being installed at the end of the connecting post.

[0006] Furthermore, the telescopic rod includes an outer tube, a movable column, and an elastic element. The outer tube is slidably connected to the slider, the movable column is slidably inserted into the outer tube, and the elastic element is telescopically disposed between the bottom wall of the outer tube and the movable column.

[0007] Furthermore, the end of the movable column away from the outer sleeve is formed with an abutment portion, which abuts against the arcuate surface of the crystallizer copper tube under the elastic force of the elastic element.

[0008] Furthermore, the abutment portion has a cutting edge on the side away from the outer sleeve that contacts the arc-shaped surface of the crystallizer copper tube.

[0009] Furthermore, one end of the outer sleeve is open, the movable column is a solid column structure, the cross-section of the outer sleeve is rectangular, and the movable column is inserted into the outer sleeve.

[0010] Furthermore, the slider has a slot, and the end of the outer sleeve is connected to a snap-fit ​​part that is slidably connected to the slot. A fixing bolt is threaded onto the snap-fit ​​part, and one end of the fixing bolt passes through the snap-fit ​​part and abuts against the bottom wall of the slot.

[0011] Furthermore, a protrusion is connected to the movable column, and an insertion hole is provided on the protrusion. The connecting column can be slidably inserted into the insertion hole. A locking bolt is threaded onto the protrusion, and one end of the locking bolt extends into the insertion hole and abuts against the connecting column.

[0012] Furthermore, of the two fixed ends, one fixed end is fixedly connected to the connecting plate, and the other fixed end is slidably connected to the connecting plate, and the two fixed ends are respectively attached to the two end planes of the crystallizer copper tube.

[0013] Furthermore, a dovetail groove is formed on the surface of the connecting plate near the arc-shaped surface of the crystallizer copper tube, one side of the slider is slidably connected to the dovetail groove, and a handle is fixedly connected to the slider.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting a telescopic rod, the end of the telescopic rod can always be in contact with the arc surface of the crystallizer copper tube when the slider slides along the connecting plate, thereby driving the marker to make an adaptive movement, ensuring that the arc drawn by the marker on the side plane of the crystallizer copper tube is consistent with the bending amplitude of the crystallizer copper tube, improving the accuracy of the marking, ensuring product quality, and being simple, convenient to operate, and with high production efficiency.

[0021] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] Please see Figures 1-4This utility model provides a marking device for slotting copper tubes in a crystallizer. It is used to mark the surface of the copper tube before slotting. Specifically, the bent copper tube 10 has two side planes 101 and two arc-shaped surfaces 102. The marking device is used to mark the side planes 101. The marking device includes a connecting plate 1, with fixed ends 11 at both ends. The fixed ends 11 are used to fix the connecting plate 1 to both ends of the copper tube 10, thereby fixing the connecting plate 1 to the copper tube 10. The connecting plate 1 has a rectangular plate structure. A slider 2 is slidably mounted on the connecting plate 1 along its length. A telescopic rod 3 is slidably mounted on the slider 2. The sliding direction of the telescopic rod 3 relative to the slider 2 is perpendicular to the sliding direction of the slider 2 relative to the connecting plate 1. Furthermore, the sliding direction of the telescopic rod 3 relative to the slider 2, the sliding direction of the slider 2 relative to the connecting plate 1, and the telescopic direction of the telescopic rod 3 are all mutually perpendicular. The side of the telescopic rod 3 away from the slider 2 rests against the arc-shaped surface 102 of the crystallizer copper tube 10. A connecting post 4 is slidably connected to the telescopic rod 3. The sliding direction of the connecting post 4 is consistent with the telescopic direction of the telescopic rod 3. A marker pen 5 is mounted at the end of the connecting post 4. The marker pen 5 is perpendicular to the connecting post 4, and the length direction of the marker pen 5 is consistent with the sliding direction of the telescopic rod 3 relative to the slider 2.

[0023] During operation, the connecting plate 1 is locked onto the crystallizer copper tube 10 by the fixed end 11 at the end of the connecting plate 1. By adjusting the telescopic rod 3, one side of the telescopic rod 3 is made to abut against the arc surface 102 of the crystallizer copper tube 10. Then, the sliding block 2 is slid relative to the connecting plate 1. During the sliding process, one side of the telescopic rod 3 always slides along the arc surface 102 of the crystallizer copper tube 10. The connecting post 4 connected to the telescopic rod 3, along with the marker pen 5, also moves together. Since one side of the telescopic rod 3 moves in an arc along the arc surface 102 of the crystallizer copper tube 10, the marker pen 5 will make an arc movement accordingly. Thus, the marker pen 5 draws an arc on the side plane 101 of the crystallizer copper tube 10. In this way, it is ensured that the drawn arc is consistent with the bending direction of the crystallizer copper tube 10, which improves the accuracy of subsequent grooving. In practice, lubricating oil can be applied to the arc-shaped surface 102 of the copper tube 10 of the crystallizer that contacts the telescopic rod 3 to reduce friction and facilitate the smooth sliding of the telescopic rod 3 along the arc-shaped surface 102.

[0024] Of the two fixed ends 11, one fixed end 11 is fixedly connected to the connecting plate 1, and the other fixed end 11 is slidably connected to the connecting plate 1. In use, the distance between the two fixed ends 11 can be changed by adjusting the movable fixed end 11 to accommodate crystallizer copper tubes 10 of different lengths. In specific implementation, one fixed end 11 is in contact with one end plane of the crystallizer copper tube 10, and the other fixed end 11 is in contact with the other end plane of the crystallizer copper tube 10.

[0025] In this embodiment, both fixed ends 11 are flat plate structures, parallel to each other and perpendicular to the connecting plate 1. One fixed end 11 is fixedly connected to the connecting plate 1 by welding, while the other fixed end 11 is slidably disposed on the connecting plate 1 using a groove and slider mechanism. For example, the connecting plate 1 has a groove, and the fixed end 11 has a slider, which is slidably connected to the groove. In a specific implementation, a lead screw 12 is rotatably mounted on the side wall of the connecting plate 1. The end of the lead screw 12 extends into the groove and is threadedly connected to the slider. In use, rotating the lead screw 12 drives the slider and the fixed end 11 to move, thereby pressing and fixing the two fixed ends 11 to both ends of the crystallizer copper tube 10. The operation is simple and efficient.

[0026] A dovetail groove 13 is formed on the surface of the arc-shaped surface 102 near the copper tube 10 of the crystallizer on the connecting plate 1 along the length direction of the connecting plate 1. One side of the slider 2 is slidably connected to the dovetail groove 13, and a handle 21 is fixedly connected to the slider 2. In use, the user pushes the slider 2 along the dovetail groove 13 by holding the handle 21.

[0027] Please refer to the following for details. Figure 4 In this embodiment, the telescopic rod 3 includes an outer sleeve 31, a movable column 32, and an elastic element 33. The outer sleeve 31 is slidably connected to the side wall of the slider 2 away from the connecting plate 1. The movable column 32 is slidably inserted into the outer sleeve 31. The elastic element 33 is telescopically disposed between the bottom wall of the outer sleeve 31 and the movable column 32. The end of the movable column 32 away from the outer sleeve 31 has an abutment portion 321. Under the elastic force of the elastic element 33, the abutment portion 321 abuts against the arcuate surface 102 of the crystallizer copper tube 10. Under the elastic force of the elastic element 33, the movable column 32 always has a tendency to extend outward, so that when the slider 2 is moved, the abutment portion 321 can always contact the arcuate surface 102 of the crystallizer copper tube 10. Furthermore, the outer sleeve 31 has a tubular structure with an opening at one end, and the movable column 32 has a solid columnar structure. The cross-section of the outer sleeve 31 is rectangular. When the movable column 32 is inserted into the outer sleeve 31, it cannot rotate relative to the outer sleeve 31, ensuring the stability of the contact between the abutment part 321 and the arc-shaped surface 102. The elastic element 33 is housed within the outer sleeve 31. One end of the elastic element 33 abuts against the bottom wall of the outer sleeve 31, and the other end of the elastic element 33 abuts against one end of the movable column 32. In one specific embodiment, the elastic element 33 is a spring.

[0028] Furthermore, a cutting edge 3211 is provided on the side of the abutment portion 321 away from the outer sleeve 31, which contacts the arc-shaped surface 102 of the crystallizer copper tube 10. The cutting edge 3211 and the arc-shaped surface 102 make contact through line and surface. By providing the cutting edge 3211 on the abutment portion 321, the contact area between the abutment portion 321 and the arc-shaped surface 102 is reduced, thereby making the lines drawn by the marker pen 5 more accurate.

[0029] In this embodiment, an inverted "U"-shaped groove 22 is formed on the surface of the slider 2 away from the connecting plate 1. One end of the outer sleeve 31 is connected to a locking part 311 that mates with the groove 22. The locking part 311 is slidable relative to the groove 22, thus preventing the outer sleeve 31 from easily detaching from the slider 2. A fixing bolt 34 is threaded onto the locking part 311. One end of the fixing bolt 34 passes through the locking part 311 and abuts against the bottom wall of the groove 22. By sliding the outer sleeve 31, the distance between the marking end of the marker pen 5 and the side plane 101 of the crystallizer copper tube 10 can be adjusted, thereby adjusting the marker pen 5 to a suitable position for easy marking. After adjustment, the user tightens the fixing bolt 34. Through the abutment of the fixing bolt 34 against the bottom wall of the groove 22 and the locking action of the groove 22 against the locking part 311, the outer sleeve 31 can be locked onto the slider 2, thereby fixing the telescopic rod 3 onto the slider 2.

[0030] A protrusion 322 is connected to the movable column 32. An insertion hole is formed on the protrusion 322 along the extension / retraction direction of the movable column 32. The connecting column 4 can be slidably inserted into the insertion hole. A locking bolt 323 is threaded onto the protrusion 322. One end of the locking bolt 323 extends into the insertion hole and abuts against the connecting column 4. In use, the position of the marker pen 5 is changed by sliding the connecting column 4, thus adjusting the distance between adjacent lines. After adjustment, the connecting column 4 is locked onto the protrusion 322 by tightening the locking bolt 323 to lock the position of the marker pen 5.

[0031] The marking device for slotting copper tubes in this invention, by setting a telescopic rod 3, ensures that the end of the telescopic rod 3 is always in contact with the arc-shaped surface 102 of the copper tube 10 when the slider 2 slides along the connecting plate 1. This causes the marker pen 5 to move adaptively, ensuring that the arc drawn by the marker pen 5 on the side plane 101 of the copper tube 10 is consistent with the bending amplitude of the copper tube 10. This improves the accuracy of marking, ensures product quality, and is simple, convenient, and efficient in operation.
