Description

Technical Field

[0002] Steel is a material of a certain shape, size and performance made from ingots, billets or steel through pressure processing.

Depending on the steel processing temperature, it can be divided into cold processing and hot processing.

[0003] The steel grinding device for steel mills is a device specially used for steel grinding processing. The grinding device is mainly used for grinding the sides, surfaces or ends of steel in steel mills to remove rust, dirt or uneven parts on the surface of steel and improve the surface quality and aesthetics of steel.

This device can find the best support point on the spherical joint by setting a mortar-shaped groove, so that the "H"-shaped steel can be stably supported when rotating. This type of steel grinding device can limit and stably support the "H"-shaped steel, and it is very convenient to adjust the grinding method, saving time and effort.

[0031] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit 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.

[0032] For example, see Figures 1 to 12 The present invention provides a technical solution for a grinding device for steel in a steelmaking plant: it includes a base 1, a collecting tank 3 is slidably connected inside the base 1, an operating seat 2 is fixedly connected to the outer wall of the top of the base 1, a rubber ring is fixedly connected to the outer wall of the top of the operating seat 2, a cylinder is arranged on the base 1, a dust cover 4 is fixedly connected to the cylinder output, a pressing plate 6 is rotatably connected to the outer wall of the cylinder output end, an extrusion mechanism is arranged inside the operating seat 2, a dust exhaust port 44 is opened at the lower part of the operating seat 2, and the bottom of the dust exhaust port 44 is connected through the top of the base 1.

[0033] By covering the outer wall of the operating seat 2 with the dust cover 4, the working area of ​​the steel can be limited to the inside of the operating seat 2, which prevents the dust from being dispersed to the outside of the operating seat 2 during the grinding process. At the same time, it also avoids accidental injury to the operator during grinding. Accordingly, through the setting of the dust cover 4, while preventing the grinding dust from flying everywhere, it also provides personal protection for the operator to prevent impurities from accidentally injuring the operator during the grinding process.

[0034] Embodiment 2, on the basis of embodiment 1, the inside of the base 1 is fixedly connected with a motor 8, the output end of the motor 8 is fixedly connected with a rotating shell 81, the outer wall at the top of the rotating shell 81 is fixedly connected with an air bin 84, the outer wall at the top of the air bin 84 is fixedly connected with the outer wall at the bottom of the emulsion shell 7, and the outer wall at the top of the emulsion shell 7 is fixedly connected with a polishing plate 5.

[0035] By rotating the air chamber 84, the emulsion shell 7 can drive the grinding plate 5 to rotate accordingly, so that the grinding plate 5 can grind the steel. The roughness, burrs, oxide scale, and rust defects on the surface of the steel can be removed by the movement of the grinding plate 5, so as to process the steel into a desired style.

[0036] Embodiment 3, on the basis of embodiment 2, the extrusion mechanism includes an emulsion shell 7, the outer wall of the emulsion shell 7 is rotatably connected to the inside of the operating seat 2, the inside of the emulsion shell 7 is slidably connected to a squeezing plate 74, the outer wall of the bottom of the squeezing plate 74 is fixedly connected to a push rod 73, the outer walls of the four push rods 73 are slidably connected to the inside of the emulsion shell 7, the outer wall of the bottom of the push rod 73 is fixedly connected to a mounting frame 71, the inside of the bottom of the mounting frame 71 is rotatably connected to a roller 72, the outer wall of the bottom of the roller 72 is movably connected to a protruding block 10, the outer wall of the top of the emulsion shell 7 is provided with a spray port, the outer wall of the spray port is connected to the inside of the grinding plate 5, and the inside of the spray port is fixedly connected to a telescopic port 75.

[0037] By providing a plurality of telescopic openings 75 on the grinding plate 5, the emulsion can be sprayed on a plurality of different positions of the steel material, thereby preventing the operator from squeezing the emulsion directly onto the steel material and then grinding it with the grinding plate 5, causing uneven dispersion of the emulsion. Accordingly, by spraying the emulsion at a plurality of positions, it can be ensured that the emulsion forms a uniform and continuous covering layer on the surface of the steel material, which prevents the accumulation, uneven dispersion or omission of the emulsion during manual application, thereby improving the utilization rate and effect of the emulsion.

[0038] Embodiment 4, on the basis of embodiment 3, a T-slot is opened above the inner wall of the dust cover 4, a T-ring 41 is rotatably connected inside the T-slot, a telescopic rod 42 is fixedly connected to the outer wall at the bottom of the T-ring 41, a connecting rod 61 is fixedly connected to the outer wall of the telescopic rod 42, the inner part of the connecting rod 61 is slidably connected to the outer wall of the telescopic rod 42, and a cleaning brush 43 is fixedly connected to the outer wall at the bottom of the telescopic rod 42.

[0039] When the cleaning brush 43 moves inside the operating seat 2, the dust inside the operating seat 2 can be cleaned, thereby preventing the operating seat 2 from being filled with dust. Since the gap between the operating seat 2 and the grinding plate 5 is small and inconvenient for the operator to clean, the grinding plate 5 can drive the cleaning brush 43 to work when it is working, and the dust polished by the grinding plate 5 can be cleaned in time, thereby preventing the waste from being accumulated in the working area and affecting the working effect of the grinding plate 5 if it is not cleaned in time. At the same time, the cleaning brush 43 can rotate with the rotation of the grinding plate 5, so that the waste can be removed in real time, thereby ensuring the cleanliness of the working area. By rotating the pressing plate 6 during the pressing process of the steel, uneven pressing force on the steel is avoided when the steel is pressed by the pressing plate 6, and accordingly ensures that all parts of the steel are subjected to uniform pressing force, thereby improving the overall quality and consistency of the steel. At the same time, the rotating pressing plate 6 helps to disperse and eliminate stress concentration points on the surface of the steel during the pressing process, reducing the risk of cracks and deformation.

[0040] Embodiment 5, on the basis of embodiment 2, the interior of the rotating shell 81 is rotatably connected to a rotating seat 85, the outer wall of the top of the rotating seat 85 is fixedly rotatably connected to a rotating shaft 88, the outer wall of the rotating shaft 88 is fixedly connected to a gear 87, the outer wall of the top of the rotating shaft 88 is fixedly connected to a dust suction blade 89, the inner ring wall of the rotating shell 81 is fixedly connected to teeth 86, the outer wall of the teeth 86 is meshingly connected to the outer wall of the gear 87, a circular hole is provided on the outer wall of the top of the grinding plate 5, a dust suction pipe 810 is fixedly connected to the inside of the circular hole, the outer wall of the dust suction pipe 810 is slidably connected to the outer wall of the extrusion plate 74, and the outer wall of the bottom of the dust suction pipe 810 passes through the interior of the emulsion shell 7 and is connected to the air bin 84.

[0041] When the suction force enters the interior of the air bin 84, the suction force can be dispersed to the interior of multiple dust suction tubes 810 through the connection between the air bin 84 and the dust suction tube 810, so that the air drives the dust on the grinding plate 5 from the interior of the dust suction tube 810 into the interior of the air bin 84, and finally intercepts it through the interception net 9. The dust on the grinding plate 5 is absorbed by the dust suction tube 810, thereby avoiding the interference of dust accumulation on the grinding effect, helping to maintain good contact between the grinding plate 5 and the steel, and improving the grinding efficiency and accuracy.

[0042] Embodiment 6. On the basis of embodiment 5, the interior of the rotating shell 81 is rotatably connected to a mounting frame 2 92, the bottom of the mounting frame 2 92 is inclined, the outer wall of the bottom of the mounting frame 2 92 is fixedly connected to a reset spring 91, the outer wall of the bottom of the reset spring 91 is fixedly connected to an interception net 9, the outer wall of the rotating shell 81 is located on one side of the interception net 9 and is provided with an ash discharge port, the outer wall of the rotating shell 81 is rotatably connected to a protective shell 82 at the position of the ash discharge port, the outer wall of the rotating shell 81 is rotatably connected to a dust exhaust pipe 83, the outer wall of the dust exhaust pipe 83 is fixedly connected to both ends of the protective shell 82, the outer wall of the dust exhaust pipe 83 is fixedly connected to the inside of the base 1, the inner wall of the rotating shell 81 is fixedly connected to an L-shaped pressure rod 93, the outer wall of the bottom of the L-shaped pressure rod 93 is in active contact with the outer wall of the top of the interception net 9.

[0043] The interception net 9 can be driven to return to its original position through the action of the reset spring 91. During the whole process, the interception net 9 will vibrate, thereby accelerating the dust to fall off the interception net 9 and enter the dust exhaust pipe 83. The vibration process not only increases the dust falling, but also realizes the automatic cleaning of the interception net 9.

[0044] Embodiment 7, on the basis of embodiment 3, a storage groove 101 is opened at the lower part of the interior of the operating seat 2, and fixing holes 104 are opened on both sides of the inner wall of the storage groove 101, a push spring is fixedly connected to the interior of the storage groove 101, and a protruding block 10 is fixedly connected to the outer wall at the top of the push spring, and cavities are opened on the outer walls on both sides of the protruding block 10, and elastic blocks 103 are fixedly connected to the interior of the cavity, and U-shaped fixing rods 102 are fixedly connected to the outer walls on the opposite sides of the two elastic blocks 103, the outer wall of the U-shaped fixing rod 102 is slidably connected to the interior of the cavity, and the outer wall of one end of the U-shaped fixing rod 102 is movably plugged into the interior of the fixing hole 104.

[0045] By fixing the raised block 10 inside the receiving groove 101, the lower part inside the operating seat 2 is a plane, and the raised block 10 will generate a thrust on the roller 72, thereby preventing the emulsion from being added when it is not needed, avoiding unnecessary consumption of the emulsion, and helping to achieve the goals of energy saving and environmental protection. At the same time, preventing the emulsion from being added by mistake helps to protect related equipment from damage or wear caused by excessive emulsion.

[0046] The working principle and use process of the present invention are as follows: when working, first, the steel to be polished is placed on the polishing plate 5, and then the cylinder can be started, and then the movement of the cylinder can drive the dust cover 4 and the pressure plate 6 to move downward. When the pressure plate 6 contacts the steel, the steel is pressed on the polishing plate 5, so as to fix the steel, thereby avoiding poor polishing effect caused by insufficient contact between the steel and the polishing plate 5 during the polishing process, and correspondingly preventing the steel from jumping during the polishing process, ensuring the uniformity of the polishing, and at the same time, by adjusting the increase or decrease of the pressure of the pressure plate 6, the depth of steel polishing can be adjusted to meet different processing requirements.

[0047] It should be noted that a pressure sensor is designed on the pressing plate 6, and the pressure sensor is connected with the control system to realize automatic adjustment and control of the pressure of the pressing plate 6. This is a prior art and will not be described in detail here.

[0048] When the pressing plate 6 contacts with the steel, the upper part of the inside of the dust cover 4 facilitates the contact of the rubber ring on the operating seat 2. At the same time, the cleaning brush 43 inside the dust cover 4 contacts with the inside of the operating seat 2. By covering the outer wall of the operating seat 2 with the dust cover 4, the working area of ​​the steel can be limited to the inside of the operating seat 2, avoiding the dust from grinding the steel to drift to the outside of the operating seat 2 with the air when the steel is being grinded, and also avoiding accidental injury to the operator during grinding. Accordingly, by setting the dust cover 4, while preventing the grinding dust from flying everywhere, the operator is also protected, and impurities are prevented from accidentally injuring the operator during the grinding process. By setting the rubber ring, the dust cover 4 is prevented from being damaged when it contacts the operating seat 2 multiple times, which correspondingly increases the service life of the dust cover 4 and the operating seat 2. By the softness of the rubber ring, when the pressing plate 6 increases the pressure, the dust cover 4 can also be moved downward on the operating seat 2.

[0049] After the steel is fixed, the motor 8 can be started, and then the rotation of the motor 8 can make the rotating shell 81 drive the air chamber 84 to rotate accordingly, and then the rotation of the air chamber 84 can make the emulsion shell 7 drive the grinding plate 5 to rotate accordingly, so that the grinding plate 5 grinds the steel. The roughness, burrs, oxide scale, and rust defects on the surface of the steel can be removed through the movement of the grinding plate 5, so that the steel can be processed into a desired style.

[0050] By rotating the emulsion shell 7, the mounting frame 71 and the roller 72 on the emulsion shell 7 can be driven to rotate inside the operating seat 2. When the roller 72 moves to the position of the protruding block 10, it moves along the inclined surface of the protruding block 10 to the top of the protruding block 10. In this rising process, the mounting frame 71 can drive the push rod 73 to move upward, and then the upward movement of the push rod 73 can push the squeezing plate 74 to squeeze the emulsion inside the emulsion shell 7 upward. The telescopic opening 75 has elasticity and generates a thrust when the emulsion moves upward, so that the outlet of the telescopic opening 75 is stretched open. At this time, the emulsion is sprayed onto the steel from the telescopic opening 75. By arranging a plurality of telescopic openings 75 on the grinding plate 5, the emulsion is sprayed on a plurality of different positions of the steel to avoid The operator is saved from squeezing the emulsion directly onto the steel material and then grinding it with the grinding plate 5, which causes uneven dispersion of the emulsion. Accordingly, by spraying the emulsion at multiple positions, it can be ensured that the emulsion forms a uniform and continuous covering layer on the surface of the steel material, which prevents the accumulation, uneven dispersion or omission of the emulsion during manual application, thereby improving the utilization rate and effect of the emulsion. The uniform distribution of the emulsion on the surface of the steel material helps to improve the cooling, lubrication and cleaning effects during the grinding process, which can not only reduce friction and heat accumulation during grinding, prevent deformation of the steel material or thermal cracks, but also improve the efficiency and accuracy of grinding. At the same time, the uniform emulsion layer can also reduce the accumulation of metal chips and impurities, and maintain the cleanliness of the grinding surface.

[0051] It should be noted that when the roller 72 falls from the inclined surface on the other side of the protruding block 10, the roller 72 can drive the push rod 73 to return to its original position when the roller 72 loses its support point. When the telescopic opening 75 loses its thrust, it can return to its original state under the elasticity of the telescopic opening 75 itself. When the emulsion is not needed to be used, the operator can press the U-shaped fixing rods 102 on both sides by hand to make the U-shaped fixing rods 102 enter the interior of the cavity, and then press the raised block 10 downward to make the raised block 10 enter the interior of the receiving groove 101, and then loosen the U-shaped fixing rod 102, so that the outer wall of one side above the U-shaped fixing rod 102 can be inserted into the interior of the fixing hole 104, thereby completing the interior of the raised block 10, and the raised block 10 can be fixed in the interior of the receiving groove 101. At this time, the lower part of the interior of the operating seat 2 is a plane, which will cause the raised block 10 to generate a thrust on the roller 72, thereby preventing the emulsion from being added when it is not needed, avoiding unnecessary emulsion consumption, and helping to achieve the goals of energy saving and environmental protection. At the same time, preventing the wrong addition of emulsion helps to protect related equipment from damage or wear caused by excessive emulsion.

[0052] The mounting frame 71 is provided with a telescopic plate inside the sliding groove of the emulsion shell 7, which moves with the up and down movement of the mounting frame 71 to prevent dust from entering the interior of the emulsion shell 7 from the inside of the sliding groove.

[0053] When the mounting bracket 71 is rotated to contact the telescopic rod 42, the mounting bracket 71 can push the telescopic rod 42 to rotate accordingly, and then the rotation of the telescopic rod 42 can drive the T-ring 41 and the cleaning brush 43 to move at the same time. When the cleaning brush 43 moves inside the operating seat 2, the dust inside the operating seat 2 can be cleaned, thereby preventing the inside of the operating seat 2 from being filled with dust. Since the gap between the operating seat 2 and the grinding plate 5 is small and inconvenient for the operator to clean, the grinding plate 5 can drive the cleaning brush 43 to work when it is working, and the dust polished by the grinding plate 5 can be removed in time to prevent these waste materials from being accumulated in the working area without being cleaned in time and affecting the working effect of the grinding plate 5. At the same time, the cleaning brush 43 rotates with the rotation of the grinding plate 5, so that these waste materials can be removed in real time to ensure the cleanliness of the working area.

[0054] The removed dust can enter the collecting tank 3 from the dust outlet 44 and be collected.

[0055] By rotating the telescopic rod 42, the connecting rod 61 can be driven to rotate accordingly, and then by rotating the connecting rod 61, the pressing plate 6 can drive the steel to rotate accordingly. The pressing plate 6 rotates during the pressing process of the steel, which avoids uneven pressing force on the steel when it is pressed by the pressing plate 6, and accordingly ensures that all parts of the steel can be subjected to uniform pressing force, thereby improving the overall quality and consistency of the steel. At the same time, the rotating pressing plate 6 helps to disperse and eliminate stress concentration points on the surface of the steel during the pressing process, reducing the risk of cracks and deformation.

[0056] By rotating the rotating shell 81, the teeth 86 can be driven to rotate accordingly, and then through the meshing connection between the teeth 86 and the gear 87, when the teeth 86 rotates, the gear 87 can be driven to move accordingly. Then, by the rotation of the gear 87, the rotating shaft 88 can drive the dust suction leaf 89 to move. During the rotation of the dust suction leaf 89, the blade shape and arrangement of the dust suction leaf 89 allow air to be sucked in and accelerated through the dust suction leaf 89. This accelerated air flow forms a low-pressure area inside the dust suction leaf 89, thereby generating suction. When the suction enters the interior of the air bin 84, the suction can be dispersed to the interior of multiple dust suction pipes 810 through the connection between the air bin 84 and the dust suction pipe 810, so that the air drives the dust on the grinding plate 5 from the inside of the dust suction pipe 810 into the inside of the air bin 84, and finally intercepts it through the interception net 9. The dust on the grinding plate 5 is absorbed by the dust suction pipe 810, thereby avoiding the interference of dust accumulation on the grinding effect, helping to maintain good contact between the grinding plate 5 and the steel, and improving the grinding efficiency and accuracy.

[0057] The dust is then filtered through the filter assembly disposed inside the rotating shell 81, allowing clean air to enter and be discharged. The exhaust ports disposed on the teeth 86 and the gears 87 will take away the heat inside the rotating shell 81 when the air is discharged. By lowering the temperature inside the rotating shell 81, the teeth 86 and the gears 87 can operate at a suitable temperature, thereby avoiding performance degradation due to overheating, and correspondingly improving the reliability of the equipment. The suitable operating temperature makes the teeth 86 and the gears 87 operate more smoothly, reducing friction and wear, thereby improving work efficiency.

[0058] When the rotating shell 81 rotates, the L-shaped pressure rod 93 can be driven to move on the interception net 9. Since the interception net 9 is inclined, when the L-shaped pressure rod 93 moves to the higher side of the interception net 9, downward pressure can be generated on the interception net 9. When the L-shaped pressure rod 93 moves to the lower side of the interception net 9, the pressure can be released. At this time, the reset spring 91 can drive the interception net 9 to return to its original position. During the whole process, the interception net 9 will vibrate, thereby accelerating the dust to fall off the interception net 9 and enter the dust exhaust pipe 83. The vibration process not only increases the dust shedding, but also realizes the automatic cleaning of the interception net 9.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
