Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a continuous casting roller surfacing equipment. Background Art

[0002] In steel production, continuous casting rollers are mainly used to keep the steel billets solidified. Under the effects of mechanical stress, thermal fatigue and metal wear caused by long-term use, the roller surface is oxidized and peeled off, which can easily cause cracks and breakage, posing safety hazards and short service life. In the prior art, surfacing technology is usually used to repair continuous casting rollers.

[0003] The structure of the existing continuous casting roller cladding machine tool is mainly composed of two parts, one is the rotation and support device of the workpiece, and the other is the transmission device for moving the welding gun. The following problems are found during use: 1) The whole machine is large in size, occupies a large space, the system is relatively complex, and the cost is high; 2) During the electrical connection between the workpiece and the electric welder, since the surface of the workpiece is not necessarily flat, there may be pits and bumps, resulting in poor conductivity and affecting the welding quality; 3) The welding slag is generally cleaned manually.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0059] See also Figures 1 to 9 As shown, this preferred embodiment provides a continuous casting roller surfacing device, including a frame 1, a rotating support device 2, a welding device 3 and a welding slag processing device 4, wherein:

[0060] The frame 1 includes a base 11 and a crossbeam 12 located above the base 11;

[0061] The rotating support device 2 comprises a main spindle box 21, a tailstock 22 and a lifting support 23 respectively arranged on the base 11. A chuck 211 and a carbon brush conductive structure 5 located behind the chuck 211 are arranged on the main spindle of the main spindle box 21. A thimble 221 is arranged on the tailstock 22. The continuous casting roller to be processed is placed horizontally on the lifting support 23, and one end of the continuous casting roller is clamped by the chuck 211 and driven to rotate, and the other end of the continuous casting roller is pressed by the thimble 221. The carbon brush conductive structure 5 is electrically conductive with the continuous casting roller.

[0062] The welding device 3 includes an electric welder 31, a transmission mechanism 32 disposed on the crossbeam 12, and a welding gun 33 driven by the transmission mechanism 32, the negative electrode of the electric welder 31 is electrically connected to the carbon brush conductive structure 5, and the positive electrode of the electric welder 31 is electrically connected to the welding gun 33;

[0063] The welding slag treatment device 4 includes a recovery tray 41 arranged on the base 11 and located below the continuous casting roller. A screen frame 42 is arranged in the recovery tray 41. The screen frame 42 includes an inclined screen plate 421, and a plurality of screen holes 422 are scattered on the screen plate 421.

[0064] Therefore, by moving the original carbon brush installation position from the continuous casting roller to the main shaft that drives the continuous casting roller to rotate, and indirectly connecting it electrically with the continuous casting roller through the chuck 211 on the main shaft that clamps the continuous casting roller, the welding circuit can be reliably conducted, thereby ensuring the quality of the continuous casting roller welding repair; and then by arranging a recovery tray 41 and a screen frame 42 under the continuous casting roller, the fallen welding slag and flux pass through the sieve plate 421 arranged obliquely on the screen frame 42, and the fine flux passes through the sieve hole 422 of the sieve plate 421 and directly falls into the recovery tray 41, while the larger sized welding slag or sintered blocks cannot pass through the sieve hole 422 and are filtered out and slide down the sieve plate 421 and accumulate together, thereby simply separating the flux from the welding slag, achieving the purpose of flux recovery, and facilitating manual later processing of the welding slag.

[0065] Specifically, see Figure 4 and Figure 5 The carbon brush conductive structure 5 includes a carbon brush bracket 51, a carbon brush unit 52 and a conductive copper plate 53, wherein:

[0066] The carbon brush holder 51 is fixed on the spindle box 21, and a through hole 511 is provided on the carbon brush holder 51 to allow the spindle to pass through;

[0067] A plurality of carbon brush units 52 are evenly distributed and installed on the carbon brush bracket 51 around the circumference of the through hole 511, and each carbon brush unit 52 includes a carbon brush block 521, and the carbon brush block 521 is in sliding contact with the main shaft;

[0068] The conductive copper plate 53 is electrically connected to the lead of each carbon brush block 521 , and the conductive copper plate 53 is electrically connected to the electric welder 31 .

[0069] It should be noted that the continuous casting roller is clamped by the chuck 211 of the main shaft box 21 and driven to rotate by the main shaft. Therefore, the continuous casting roller is conductive with the chuck 211, the main shaft, the slewing support 212, etc. However, some parts on the main shaft box 21 cannot accept electrical conduction, such as the bearing body in the slewing support 212. The current passing through the bearing body can easily burn it out. Therefore, in order to ensure reliable electrical conduction with the continuous casting roller and not damage the parts on the main shaft box 21, it is better to set the conductive position on the main shaft and between the chuck 211 and the slewing support 212.

[0070] Furthermore, the carbon brush unit 52 also includes a carbon brush fixing seat 522, which is fixed on the carbon brush bracket 51. A limit block 523 is provided on the carbon brush fixing seat 522 and at one end of the carbon brush block 521 facing away from the main shaft. A spring 524 is provided between the carbon brush block 521 and the limit block 523. The spring 524 is used to press the carbon brush block 521 so that the carbon brush block 521 keeps in contact with the main shaft. Since the surface roughness of the main shaft is small and the roundness is high, each carbon brush block 521 can ensure reliable contact with the main shaft circumference, and as the main shaft rotates and wears the carbon brush block 521, the spring 524 can gradually press the carbon brush block 521 to feed, further ensuring the conductive effect of the carbon brush and the continuous casting roller.

[0071] In particular, a plurality of mounting slots 525 are provided on the carbon brush fixing seat 522 along the direction of the carbon brush block 521 toward the main axis, and the limit block 523 is installed in any mounting slot 525, so that the pressing force of the spring 524 on the carbon brush block 521 can be adjusted, so as to adjust the force of the spring 524 according to the wear of the carbon brush block 521 and make full use of the carbon brush block 521.

[0072] Furthermore, a limit frame 526 is provided on the carbon brush fixing seat 522, and the carbon brush block 521 passes through the limit frame 526, so that the carbon brush block 521 moves accurately and stably during the feeding process relative to the main shaft, thereby ensuring the conductive effect.

[0073] In particular, the conductive copper plate 53 is fixed by the lead wires of each carbon brush block 521 and is suspended in the air, so that the conductive copper plate 53 does not contact the carbon brush bracket 51 to avoid affecting the welding circuit. In order to facilitate the installation of the conductive copper plate 53, the mounting plate and the main shaft, the conductive copper plate 53 and the mounting plate can be designed as a split structure.

[0074] In addition, with the structure of the annularly distributed carbon brush units 52 , when there are multiple welding guns 33 , some of the carbon brush units 52 can be selected to be connected to a corresponding welding gun 33 , thereby reducing the wiring difficulty and ensuring the normal use of each welding gun 33 .

[0075] Specifically, Figure 6As shown, at least two lifting supports 23 are provided to form a stable support for the horizontal continuous casting rollers. Each lifting support 23 includes a lift 231 arranged upward, and a support platform 232 is provided on the output end of the lift 231. Two rollers 233 with adjustable spacing are provided on the support platform 232. The two rollers 233 support both sides of the continuous casting roller, and the rollers 233 are in rolling contact with the surface of the continuous casting roller, so that the continuous casting roller can rotate freely while being supported. Furthermore, in order to improve the stability of the support platform 232, guide columns 234 for limiting and guiding the support platform 232 are provided on both sides of the lift 231.

[0076] Specifically, see Figure 7 The transmission mechanism 32 includes a slide module 321 that moves along the axial direction of the main shaft, and a first slide 322 that is perpendicular to the axial direction of the main shaft and moves vertically is arranged on the slide module 321, and a second slide 323 that is perpendicular to the axial direction of the main shaft and moves horizontally is arranged on the first slide 322, and a swing mechanism 324 and a hopper 34 are arranged on the second slide 323, and a wire feeder 35 is arranged at the output end of the swing mechanism 324, and the hopper 34 is connected with the feed port of the wire feeder 35, and the welding gun 33 is arranged at the discharge port of the wire feeder 35, so that the welding gun 33 can be moved and rotated to any welding position and welding angle to meet the requirements of surfacing welding, and multiple slide modules 321 can be installed on the beam 12 as needed to set up multiple welding guns 33 accordingly, and weld multiple positions simultaneously to improve processing efficiency, and sufficient carbon brush units 52 are reserved in the aforementioned carbon brush conductive structure 5 to be electrically connected with the corresponding welding gun 33 and the electric welder 31.

[0077] Furthermore, a scraping mechanism 36 is also provided on the slide module 321, and the scraping mechanism 36 is used to clean the welding surface of the continuous casting roller to scrape off the excess surfacing layer thickness and surface defects of the continuous casting roller, thereby improving the surfacing quality.

[0078] Specifically, see Figure 8 and Fig. 9 The screen frame 42 includes a frame 423 for mounting a screen plate 421, and legs 424 are provided at the four corners of the frame 423. The four legs 424 are inserted into the recovery tray 41, and the legs 424 are against the side walls of the recovery tray 41. The frame 423 is hollow, and the screen plate 421 is laid on the frame 423, and the screen plate 421 and the frame 423 are fixed by a pressure strip 425. The high end of the screen plate 421 is located directly below the continuous casting roller, and the frame 423 is provided with a low end higher than the screen plate 421 and a retaining edge 426 on both side edges to limit the filtered flux.

[0079] As a result, it is convenient to combine and separate the screen frame 42 and the recovery plate 41, and the screen frame 42 can be ensured to be placed stably when combined, and it is convenient to handle the flux and welding slag separately when separated; in addition, since the temperature of welding slag is very high, the screen plate 421 is a consumable part and needs to be replaced regularly. The structure fixed by the pressure strip 425 is convenient for the installation and replacement of the screen plate 421, and the size of the screen hole 422 can also be continuously adjusted according to the screening effect.

[0080] Preferably, the inclination angle of the sieve plate 421 is 15° to 30°. At this angle, the slag and flux that fall from the high end of the sieve plate 421 and do not pass through the sieve holes 422 can slide freely along the sieve plate 421 and be further screened during the sliding process.

[0081] In particular, the recovery tray 41 is directly placed on the base 11, and two limit bars 411 are provided at the bottom of the recovery tray 41. The two limit bars 411 are abutted against the two sides of the base 11, so that the recovery tray 41 can translate along the base 11 according to the welding position of the continuous casting roller, that is, it can move with the position of the welding gun 33 or the slag scraping mechanism 36, thereby reducing the volume of the recovery tray 41 and the screen frame 42, and improving the utilization rate of the recovery tray 41 and the screen frame 42.

[0082] In summary, the continuous casting roller surfacing equipment has the following advantages:

[0083] 1) High degree of automation;

[0084] 2) High repair efficiency, rotary electrode deposition welding, easy operation and high work efficiency;

[0085] 3) Easy to operate, maintain and service;

[0086] 4) Save costs, by repairing damaged rollers, the service life of the rollers can be extended;

[0087] 5) Environmental protection and energy saving, surfacing repair can reduce the generation of discarded rolls and reduce the impact on the environment.

[0088] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
