Description

Technical Field

[0001] The invention relates to the field of oxide scale removal processing, and in particular to flexible and efficient oxide scale removal equipment and method for multi-material-based composite surfaces. Background Art

[0002] Billets are steel billets. Billets with four sides of equal length are called billets; billets with rectangular cross sections are called rectangular billets. The side length of a large billet is not less than 200mm; the side length of a small billet is less than 200mm; the width-to-thickness ratio of a rectangular billet is generally 1.3-1.5. Rectangular billets with a cross-sectional area of ​​not less than 40000mm2 are large billets. After the billet casting process, due to the rapid cooling of the surface and the oxidation reaction with oxygen in the air, the outer surface of the small billet often produces different degrees of iron oxide scale. The formation process of iron oxide scale is also the diffusion process of oxygen and iron. Oxygen diffuses from the surface to the inside of the iron, while iron diffuses to the outside. As a by-product of the billet casting process, iron oxide scale can be cleaned and collected as a raw material for the manufacture of sponge iron. Compared with sponge iron produced from ore, it does not contain gangue impurities and can be used as a high-quality scrap steel raw material. At the same time, reduced iron powder can be manufactured by rough reduction or fine reduction. In China, iron oxide scale has formed large-scale industrial production as a sintering raw material. The production of ferrosilicon alloy using iron oxide scale has a simple process and a trend of large-scale production. However, in the process of treating iron oxide scale of small steel billets, the following problems often occur:

[0003] (1) In the process of cleaning the oxidized iron scale on the surface of the small square billet, due to the stability of the shape and structure of the small square billet itself, the contact area between the small square billet and the surrounding space is large, which is easy to form a shielding cover on the oxidized iron scale. The traditional cleaning process is difficult to clean the outer surface of the small square billet simultaneously. The debris in the cleaning process is easy to form secondary adsorption accumulation on other layers, resulting in low cleaning efficiency.

[0004] (2) In the process of cleaning the surface oxide scale of the small square billet, it is difficult to reduce the workload of the grinding belt through multi-station and multi-angle oxide scale stripping pretreatment operations, which easily causes heat accumulation and the generation of oxide scale dust, reducing the service life of the treatment system and the collection efficiency of the oxide scale. Summary of the invention

[0005] In view of the problems in the prior art, the present invention provides flexible and efficient equipment and method for removing oxide scale from the surface of multi-material-based composite materials.

[0006] The technical solution adopted by the present invention to solve its technical problems is: flexible and efficient equipment for removing oxide scale on the surface of multi-material-based composite materials, including a substrate, supporting feet, a guide frame, a guiding mechanism, a cleaning mechanism, a blanking trough, a load-bearing seat and a load-bearing rotating shaft. Supporting feet are arranged at the corners around the lower end of the substrate, and load-bearing seats are symmetrically installed on the upper ends of the front and rear sides of the substrate. The load-bearing rotating shafts are symmetrically installed on the left and right sides of the upper end of the load-bearing seat through rotational cooperation. Blanking troughs are evenly opened in the middle of the substrate, and a guide frame is installed on the upper end of the substrate, and the guide frame is located between the load-bearing seats. The guide mechanism is installed on the upper end of the guide frame. The cleaning mechanism is installed on the upper end of the substrate, and the cleaning mechanism is located in the middle of the guide frame and the cleaning mechanism is located between the guide mechanisms.

[0007] The cleaning mechanism comprises a fixed ring, a cleaning shaft, a cleaning gear, a chain, a close ring, a close shaft, a grinding belt and a cleaning motor. A fixed ring is fixedly installed symmetrically front and back at the middle part of the upper end of the substrate, and a cleaning shaft is symmetrically installed on the fixed ring along its diagonal direction through a bearing. One end of the cleaning shaft is located between the fixed rings of the double-layer structure and the end portions of the cleaning shaft are all installed with cleaning gears through key connection. The cleaning gears arranged circumferentially are connected by chain transmission. A cleaning motor is fixedly installed on one side of the fixed ring through a motor seat. The output shaft of the cleaning motor is connected to one of the cleaning shafts through a coupling. A close ring is fixedly installed on the inner side of the fixed ring, and a close shaft is movably installed on the close ring along its circumference. The close shaft and the cleaning shaft are arranged at intervals and are connected by grinding belt transmission. The grinding belts staggered with each other at multiple stations can completely grind the outer wall of the small square billet at the same time, and by giving way to each other, the debris generated during the grinding process can fall unhindered.

[0008] Specifically, the proximity ring also includes a proximity groove, a proximity slider and an alignment bolt. The arc outer ring surface of the proximity ring is evenly provided with proximity grooves along its circumference. The proximity slider is installed in the proximity groove by sliding fit. The top of the proximity groove is installed with an alignment bolt by thread fit, and one end of the alignment bolt is rotatably connected to the proximity slider, and one end of the proximity shaft is transmission connected to the proximity slider by rotational fit.

[0009] Specifically, the cleaning shaft and the two adjacent proximal shafts are arranged in a triangle shape as a whole, and the grinding belt sleeves are arranged on the diagonally distributed proximal shafts and the cleaning shaft.

[0010] Specifically, there are four grinding belts. The two grinding belts on the same side of the fixed ring are distributed diagonally in a rectangular shape. The side walls of the grinding belts are evenly inclined with scraper strips. The scraper strips arranged at inclined intervals can increase the debris falling rate while quickly dissipating the heat generated by the grinding process through the reserved gap, thereby improving the stability and safety of the system operation.

[0011] Specifically, the fixed ring also includes a profiling frame, a spacing plate, an extrusion rod and an extrusion ball. The outer contour of the arc side wall of the fixed ring is evenly installed with a profiling frame along its circumference. Both end portions of the profiling frame extend to the outside of the grinding belt and both end portions of the profiling frame are fixedly installed with a spacing plate. The extrusion rod is movably installed on the spacing plate. The circumferentially arranged extrusion rods are staggered in space and the inner sides of the extrusion rods are installed with extrusion balls by means of rotational cooperation.

[0012] Specifically, the guide mechanism includes a U-shaped frame, a guide shaft, a guide rod and a guide wheel. The U-shaped frame is installed on the upper end of the guide frame, and the guide shaft is symmetrically installed on the middle part of the U-shaped frame through a key connection. The guide rods are evenly installed along the linear arrangement in the middle part of the guide shaft, and the guide wheels are evenly installed on the guide rods through a rotational fit.

[0013] Specifically, the guide rods are all installed on the guide shafts at an angle, and the guide rods and the load-bearing shaft have the same inclination direction.

[0014] Specifically, spiral grooves are evenly arranged along the side walls of the guide rod, and anti-skid teeth are installed in the spiral grooves. The spiral grooves and anti-skid teeth arranged in a spiral shape can rotate themselves in the process of following the sliding of the small square billet, thereby reducing the external resistance encountered by the small square billet during the pushing and sliding process.

[0015] Specifically, the load-bearing shafts are all installed obliquely on the upper end of the load-bearing seat, and the angle between the load-bearing shafts located on the left and right sides of the load-bearing seat is a right angle. The lateral support of the small square billet by the load-bearing shafts and the guide rods can make the four side walls of the small square billet in an inclined position, and the contact area between the small square billet and the surrounding space during the pushing process can be reduced so that the iron oxide scale on the side wall of the small square billet can be fully exposed.

[0016] In addition, the present invention also provides a flexible and efficient method for removing oxide scale from the surface of a multi-material composite material, comprising the following steps:

[0017] The first step: hoist the small square billet to be cleaned of oxidized iron scale to the top of the bearing seat, then overlap one end of the small square billet on the bearing shaft, and under the guiding and limiting action of the inclined bidirectional bearing shaft, the small square billet is naturally turned over, and then the staff pushes the exposed end to fit it on the bearing shaft for movement;

[0018] Step 2: During the process of pushing and moving the billet, its end portion further overlaps and enters into the gap between the guide rods after passing through the load-bearing shaft. During the process of the guide wheel being in contact with the outer wall of the billet, the spiral groove and the anti-skid teeth arranged in a spiral shape can rotate themselves in the process of following the sliding of the billet, thereby reducing the external resistance encountered during the pushing and sliding of the billet. Moreover, due to the gravity of the billet itself, the anti-skid teeth can also cut off and crush the oxidized iron scale protruding on the side wall of the lower half of the billet, so that the oxidized iron scale falls naturally and passes through the blanking chute.

[0019] Step 3: The lateral support of the billet by the load-bearing shaft and the guide rod can make the four side walls of the billet in an inclined state. The contact area between the billet and the surrounding space during the pushing process is reduced so that the oxidized iron scale on the side wall of the billet can be fully exposed. At the same time, the oxidized iron scale can be removed by pushing the billet in an inclined side direction.

[0020] Beneficial effects of the present invention:

[0021] (1) The flexible and efficient removal equipment and method for oxide scale on the surface of multi-material composite materials described in the present invention can rotate itself in the process of following the sliding of the small square billet through the spiral groove and anti-skid teeth arranged in a spiral shape, thereby reducing the external resistance encountered by the small square billet during the pushing and sliding process. In addition, due to the gravity of the small square billet itself, the anti-skid teeth can also cut and crush the protruding oxide scale on the side wall of the lower half of the small square billet, so that the oxide scale naturally falls and passes through the blanking chute. The lateral support of the small square billet by the load-bearing shaft and the guide rod can make the four side walls of the small square billet in an inclined position. By reducing the contact area between the small square billet and the surrounding space during the pushing process, the oxide scale on the side wall of the small square billet can be fully exposed. At the same time, by pushing the small square billet in an inclined position on the side, the mechanical vibration generated during the pushing and cleaning process can be fully optimized and utilized, thereby improving the dropping rate and dropping effect of the oxide scale on the inclined side of the small square billet during the cleaning process.

[0022] (2) The flexible and efficient removal equipment and method for oxide scale on the surface of multi-material composite materials described in the present invention can completely grind the outer wall of the small square billet through the grinding belts staggered at multiple stations, and allow the debris generated during the grinding process to fall unhindered by giving way to each other. The scraping strips arranged at inclined intervals can increase the debris falling rate while the heat generated during the grinding process can be quickly dissipated through the reserved gaps, thereby improving the stability and safety of the system operation;

[0023] (3) The flexible and efficient removal equipment and method for oxide scale on the surface of multi-material composite materials described in the present invention can reduce the operating load of the grinding belt and the scraper strip by performing multi-station and multi-angle oxide scale stripping pretreatment operations on small square billets through the load-bearing rotating shaft, guide wheel, extrusion rod and extrusion ball. The operation of the grinding belt under a smaller load can reduce the degree of crushing of the oxide scale and reduce the generation of dust. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] See also Figure 4 , Figure 6 , Figure 8 , Fig.10 and Fig.11The cleaning mechanism 5 includes a fixed ring 51, a cleaning shaft 52, a cleaning gear 53, a chain 54, a close ring 55, a close shaft 56, a grinding belt 57 and a cleaning motor 58. The fixed ring 51 is symmetrically fixedly installed in the middle of the upper end of the substrate 1. The cleaning shaft 52 is symmetrically installed on the fixed ring 51 along its diagonal direction through a bearing. One end of the cleaning shaft 52 is located between the fixed rings 51 of the double-layer structure and the end of the cleaning shaft 52 is installed with a cleaning gear 53 by a key connection. The cleaning gears 53 arranged in the circumferential direction are connected by a chain 54. A cleaning motor 58 is fixedly installed on one side of the fixed ring 51 through a motor seat.

[0043] See also Figure 7 and Fig. 9 The proximity ring 55 also includes a proximity groove 551, a proximity slider 552 and a positioning bolt 553. The arc outer ring surface of the proximity ring 55 is evenly provided with proximity grooves 551 along its circumference. The proximity slider 552 is installed in the proximity groove 551 by sliding fit. The top of the proximity groove 551 is installed with a positioning bolt 553 by thread fit, and one end of the positioning bolt 553 is rotatably connected to the proximity slider 552, and one end of the proximity shaft 56 is transmission connected to the proximity slider 552 by rotation fit.

[0044] During the specific operation, during the pushing process of the small square billet 00, the positioning bolt 553 is rotated manually using an instrument, and the position of the close slider 552 in the close slide groove 551 is adjusted by rotating the positioning bolt 553, and the close shaft 56 is driven to move synchronously by the close slider 552, and the grinding belt 57 is further driven to move synchronously, and the interval between the grinding belts 57 is adjusted according to the actual circumference size of the small square billet 00.

[0047] In addition, the present invention also provides a method for removing oxide scale on the surface of a multi-material-based composite material, comprising the following steps:

[0048] When working:

[0049] The first step: first, the small square billet 00 to be cleaned of oxidized iron scale is hoisted to the top of the load-bearing seat 7 by the existing crane, and then one end of the small square billet 00 is overlapped on the load-bearing shaft 8. Under the guiding and limiting action of the inclined bidirectional load-bearing shaft 8, the small square billet 00 is naturally turned over, and then the staff pushes the exposed end and makes it fit on the load-bearing shaft 8 for movement;

[0050] Step 2: During the process of pushing and moving the small square billet 00, its end portion further overlaps and enters into the gap between the guide rods 43 after passing through the load-bearing shaft 8. During the process of the guide wheel 44 being in contact with the outer wall of the small square billet 00, the spiral groove 431 and the anti-skid teeth 432 arranged in a spiral shape can rotate themselves in the process of following the sliding of the small square billet 00, thereby reducing the external resistance encountered by the small square billet 00 during the pushing and sliding process. In addition, due to the gravity of the small square billet 00 itself, the anti-skid teeth 432 can also cut and crush the protruding iron oxide scale on the side wall of the lower half of the small square billet 00. , so that the oxidized iron scale falls naturally and passes through the blanking chute 6, and the lateral support of the small square billet 00 by the load-bearing shaft 8 and the guide rod 43 can make the four side walls of the small square billet 00 in an inclined position, and the contact area between the small square billet 00 and the surrounding space during the pushing process can be reduced so that the oxidized iron scale on the side wall of the small square billet 00 can be fully exposed. At the same time, by pushing the small square billet 00 in an inclined position at the side, the mechanical vibration generated during the pushing and cleaning process can be fully optimized and utilized, thereby improving the dropping rate and dropping effect of the oxidized iron scale on the oblique side of the small square billet 00 during the cleaning process;

[0051] Step 3: During the pushing process of the small square billet 00, the alignment bolt 553 is manually rotated by using an apparatus, and the position of the close slider 552 in the close slide groove 551 is adjusted by rotating the alignment bolt 553, and the close shaft 56 is driven to move synchronously by the close slider 552, and the grinding belt 57 is further driven to move synchronously, and the interval between the grinding belts 57 is adjusted according to the actual circumference size of the small square billet 00. After that, the cleaning motor 58 is started to operate, and one of the cleaning shafts 52 is driven to rotate by the cleaning motor 58, and the circumferential cleaning shaft 52 is further driven to rotate synchronously by the transmission connection between the cleaning gear 53 and the chain 54. During the rotation of the cleaning shaft 52, the grinding belt 57 and the close shaft 56 are driven to rotate synchronously by friction resistance. When the small square billet 00 enters the gap surrounded by the grinding belt 57, the cleaning and grinding operation of the oxidized iron scale is realized by the rotation of the grinding belt 57. The grinding belts 57 staggered with each other at multiple stations can completely grind the outer wall of the small square billet 00, and the debris generated in the grinding process can fall unhindered by giving way to each other. The scraping strips 571 arranged at inclined intervals can increase the falling rate of the debris and quickly dissipate the heat generated in the grinding process through the reserved gap, thereby improving the stability and safety of the system operation.

[0052] Step 4: During the pushing and moving of the billet 00, when its outer wall passes through the space surrounded by the extrusion rod 513, the extrusion balls 514 are in contact with the outer wall of the billet 00 by means of rotational cooperation, and some of the iron oxide scale with a large degree of warping is peeled off by itself under the blocking effect of the extrusion rod 513. Due to the high brittleness of the iron oxide scale, the remaining iron oxide scale gradually cracks and collapses under the rolling and extrusion effect of the extrusion balls 514. Although it is still attached to the side wall of the billet 00, it is The subsequent grinding and scraping action of the grinding belt 57 and the scraper strip 571 can quickly drop off, further improving the efficiency of the oxidized iron scale cleaning operation of the small square billet 00. The multi-station and multi-angle oxidized iron scale stripping pretreatment operation of the small square billet 00 by the load-bearing rotating shaft 8, the guide wheel 44, the extrusion rod 513 and the extrusion ball 514 can reduce the operating load size of the subsequent grinding belt 57 and the scraper strip 571, so that the grinding belt 57 can be operated under a smaller load to reduce the degree of crushing of the oxidized iron scale and reduce the generation of dust.

7. A method for the flexible and efficient removal of oxide scale on the surface of a multi-material-based composite material, the method being applicable to the flexible and efficient removal of oxide scale on the surface of a multi-material-based composite material as claimed in any one of claims 1 to 6, characterized in that: The method comprises the following steps: The first step is to lift the small square billet to be cleaned of oxidized iron scale to the top of the bearing seat (7), and then overlap one end of the small square billet on the bearing shaft (8). Under the guiding and limiting action of the inclined bidirectional bearing shaft (8), the small square billet is naturally turned over, and then the exposed end is pushed by the staff to fit on the bearing shaft (8) for movement; Step 2: During the process of pushing and moving the billet, the end of the billet passes through the load-bearing shaft (8) and then overlaps and enters the gap between the guide rods (43). During the process of the guide wheel (44) being in contact with the outer wall of the billet, the spiral groove (431) and the anti-skid teeth (432) arranged in a spiral shape can rotate themselves while following the sliding of the billet, thereby reducing the external resistance encountered by the billet during the pushing and sliding process. In addition, due to the gravity of the billet itself, the anti-skid teeth (432) can also cut off and crush the iron oxide scale protruding from the side wall of the lower half of the billet, so that the iron oxide scale falls naturally and passes through the blanking chute (6). Step 3: The load-bearing shaft (8) and the guide rod (43) provide lateral support to the billet, so that the four side walls of the billet are placed in an inclined state. The contact area between the billet and the surrounding space during the pushing process is reduced so that the iron oxide scale on the side wall of the billet can be fully exposed. At the same time, the removal of the iron oxide scale is achieved by pushing the billet in an inclined manner.
