Description

Technical Field

[0001] The invention belongs to the field of grinding machines, and relates to a grinding machine for processing steel ingots which can be adjusted for grinding at multiple angles. Background Art

[0002] Large steel ingots are rectangular structures with a length of up to 12m, a width of up to 4m, and a thickness of up to 1m. Large steel ingots can be used for plate rolling operations. Before rolling, the surface quality of the steel ingots needs to be tested to avoid tiny cracks on the surface of the steel ingots, otherwise long cracks will be formed on the plates after rolling, greatly affecting the quality of the plates.

[0003] In order to eliminate the tiny cracks on the ingot, a grinder can be used to grind the crack position to eliminate the adverse effects of the cracks. In the current technology, the surface flatness of the ingot is low and the directions of the cracks are different. Therefore, the position and direction of the grinder need to be adjusted to try to grind along the direction of the cracks. After grinding, pits will inevitably be formed on the surface of the ingot, and the sides of the pits on both sides of the grinding wheel are vertical surfaces. At this time, rolling the ingot may cause the steel on both sides of the pit to be squeezed into the pit. After multiple squeezing, scars or indentations will form on the surface of the steel plate. In order to avoid the above defects, workers need to control the grinder to grind on both sides of the pit multiple times, forming a step shape on the vertical pit side, and minimizing the adverse effects of grinding on subsequent processing. It is not difficult to find that the current grinder has the defects of complex operation and the grinding quality cannot fully meet the rolling requirements of the ingot. Summary of the invention

The driving motor 21 drives the driving roller 22 to rotate around the horizontal center line. The swinging screw 23 is horizontally arranged in the driving roller 22. There are four swinging screws 23, which are evenly arranged circumferentially along the horizontal center line of the driving roller 22. A swing driving member 24 is also provided on the driving roller 22 on one side of each swing screw 23, and the output shaft of the swing driving member 24 is fixedly connected to the end of the swing screw 23.

[0026] In some examples, the lifting mechanism 1 may be a hydraulic cylinder, the cylinder body of the hydraulic cylinder is fixed to the ground, the piston of the hydraulic cylinder reciprocates in the vertical direction, and the piston of the hydraulic cylinder is fixedly connected to the grinding wheel drive mechanism 2. A rotating mechanism may be provided between the lifting mechanism 1 and the grinding wheel drive mechanism 2, and the rotating mechanism may include a rotating motor and a reducer, both of which are fixedly connected to the piston of the hydraulic cylinder, the output shaft of the rotating motor is coaxially fixedly connected to the input shaft of the reducer, and the output shaft of the reducer is fixedly connected to the grinding wheel drive mechanism 2.

[0027] The lifting mechanism 1 can control the vertical position of the grinding wheel driving mechanism 2, and the rotating mechanism can control the horizontal deflection angle of the grinding wheel driving mechanism 2. Of course, the multi-angle adjustable grinding machine for steel ingot processing described in the present application can also be set on a track, so that the multi-angle adjustable grinding machine for steel ingot processing can be moved to various positions above the steel ingot to adapt to cracks at different positions on the surface of the steel ingot.

[0028] The grinding wheel drive mechanism 2 also includes a connecting bracket 27, which can be a U-shaped piece. The driving roller 22 is arranged on the inner side of the U-shaped piece and is connected to the driving roller 22 through a bearing. The driving motor 21 is arranged in the driving roller 22, and one end of the U-shaped piece is fixedly connected to the outer casing of the driving motor 21.

[0029] The driving roller 22 may include a cylinder 221 with openings at both ends and a spherical shell 222 fixed to the outside of the cylinder 221, and the driving motor 21 is arranged inside the cylinder 221. Ball bearings may be arranged between the driving motor 21 and the inner wall of the driving roller 22 to ensure that the cylinder 221 can rotate around the driving motor 21, and the stability between the cylinder 221 and the driving motor 21 is sufficient, and the output end of the driving motor 21 is fixedly connected to the inner wall of the driving roller 22.

[0030] Four swing screws 23 are arranged between the outer side of the cylinder 221 and the inner side of the spherical shell 222. The swing screws 23 are evenly arranged around the outer side of the cylinder 221. Both ends of the swing screws 23 are connected to the side wall of the cylinder 221 through bearings. The swing screws 23 are connected to one end of the swing connection member 26. When the swing screws 23 are driven to rotate, the swing screws 23 can drive the swing connection member 26 to reciprocate along the extension direction of the swing screws 23, wherein the swing screws 23 are driven to rotate by the swing driving member 24.

[0031] The spherical shell 222 is provided with a plurality of movable grooves, the center lines of the movable grooves are coplanar with the center line of the cylinder 221, and the plurality of movable grooves are evenly arranged around the center line of the spherical shell 222. A slider is provided in each movable groove, and it can be understood that the slider has an arc groove adapted to the spherical shell 222, so that the slider can slide back and forth in the movable groove, and the other end of the swing connection 26 is fixedly connected to a corresponding slider, that is, the swing screw 23 can drive the slider to reciprocate along the extension direction of the swing screw 23 through the swing connection 26, and of course the swing connection 26 has the ability to extend and retract in its extension direction.

[0032] In this application, if Figure 6 As shown, the swing connection member 26 includes: a swing nut 261, a sleeve 262, a piston rod 263 and a hinge 264. The swing nut 261 is adapted to the swing screw 23, and the swing nut 261 is movably mounted on the corresponding swing screw 23. The sleeve 262 is fixedly connected to the swing nut 261, and the sleeve 262 is a pipe with an open end. The piston rod 263 is a straight rod, and the piston rod 263 is movably arranged in the sleeve 262, and the sleeve 262 drives the piston rod 263 to reciprocate along the extension direction of the horizontal center line. One end of the hinge 264 is fixedly connected to the piston rod 263, and the other end of the hinge 264 is fixedly connected to the slider, and the hinge 264 can be a ball joint.

[0033] When the swing screw rotates, the swing nut 261 can be controlled to reciprocate along the swing screw by controlling the forward and reverse rotation of the swing driving member, and at the same time drive the sleeve 262 and the piston rod 263 to reciprocate, that is, drive the slider to reciprocate along the extension direction of the swing screw. The sleeve 262 and the piston rod 263 enable the swing connector 26 to have the ability to extend and retract in its extension direction, and the hinge 264 can drive the slider to reciprocate while taking into account the deflection angle of the slider in the movable groove.

[0034] A grinding wheel assembly 25 is movably mounted on the outside of the spherical housing 222. The grinding wheel assembly 25 is an annular structure and may include: a slip ring 251 and a grinding wheel 252. The slip ring 251 is an annular member, and a plurality of sliders are fixedly connected to the inner wall of the slip ring 251. The grinding wheel 252 is an annular structure and is clamped on the outside of the slip ring 251. It is understandable that the outer side surface of the slip ring 251 may be set as a stepped cylindrical surface, and the grinding wheel 252 is mounted on the slip ring 251 and is fixedly connected to the slip ring 251 through an annular baffle.

[0035] When the sliders are running, for example, when the two sliders arranged oppositely are running in opposite directions, the grinding wheel assembly 25 can realize angular swing, and when the driving roller 22 rotates, the grinding wheel assembly 25 can be driven to rotate. In this way, the grinding wheel assembly 25 rotates and the angular swing is free; wherein, the two sliders arranged oppositely refer to the sliders whose center lines of the two movable grooves are coplanar and are located in the two movable grooves.

[0036] In the present application, the driving motor 21 drives the grinding wheel assembly 25 to rotate, and at the same time, the grinding wheel assembly 25 can swing relative to the driving motor 21 without affecting the stability of the transmission components of the driving motor 21 and the grinding wheel assembly 25.

[0037] Of course, the steel ingot processing grinding machine with multi-angle adjustable grinding described in the present application is specially used for steel ingot grinding. Since the composition of the steel ingot is stable, it is only necessary to control the downward pressure on the grinding wheel drive mechanism 2 to avoid the grinding wheel assembly 25 from being locked. Therefore, the use of rigid transmission between the drive motor 21 and the grinding wheel assembly 25 will not have a significant impact on the equipment failure rate.

[0038] In some embodiments, Figure 2 and Figure 5 As shown, the grinding wheel driving mechanism 2 further includes a hydraulic oil pump 28, the hydraulic oil pump 28 is fixedly connected to the driving roller 22, and the input shaft of the hydraulic oil pump 28 is connected to the driving motor 21. The swing driving member 24 further includes a hydraulic motor, and the two spaced hydraulic motors are connected to the hydraulic oil pump 28 in sequence, and the output shafts of the two spaced hydraulic motors rotate in opposite directions.

[0039] The grinding wheel driving mechanism 2 further includes: a driving gear and a driven gear. The driving gear is coaxially fixedly connected to the center wheel. The diameter of the driven gear is smaller than the diameter of the driving gear, the driven gear meshes with the driving gear, and the driven gear is coaxially fixedly connected to the input shaft of the hydraulic oil pump 28.

[0040] The grinding wheel drive mechanism 2 also includes a flow control valve 29 and an electromagnetic reversing valve 210. The flow control valve 29 includes two oil outlets and one oil inlet, the oil inlet is connected to the oil outlet of the hydraulic oil pump 28, one oil outlet of the flow control valve 29 is connected to the A port of the electromagnetic reversing valve 210, the P port of the electromagnetic reversing valve 210 is connected to the two hydraulic motors spaced apart in sequence and then to the T port of the electromagnetic reversing valve 210, the B port of the electromagnetic reversing valve 210 is connected to the oil tank 211, and the other oil outlet of the flow control valve 29 is connected to the oil tank 211.

[0041] like Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the flow control valve 29 includes: a valve body 291, a valve core 292, a valve cover 293 and a telescopic member 294. The valve body 291 is provided with a blind hole with a square cross section, and the valve body 291 is also provided with two oil outlet holes 2911, the two oil outlet holes 2911 are connected with the blind hole 2912, and the center lines of the two oil outlet holes 2911 and the center line of the blind hole 2912 are coplanar, and the two oil outlet holes 2911 are connected with the two oil outlet ports in a one-to-one correspondence, and the valve body 291 is also provided with two oil inlet holes, the two oil inlet holes are connected with the blind hole, and the center lines of the two oil inlet holes and the center line of the blind hole 2912 are coplanar, and each oil inlet hole is also coplanar with a corresponding oil outlet hole 2911, and the two oil inlet holes are both connected with the oil inlet.

[0042] The valve core 292 is a cubic structure adapted to the blind hole. The height of the valve core 292 is also adapted to the diameter of the oil outlet hole. The valve core 292 has a tendency to reciprocate along the center line of the blind hole. The sum of the flow areas of the two oil outlet holes controlled by the valve core 292 is the same as the cross-sectional area of ​​one oil outlet hole. A valve cover 293 is provided at the opening end of the blind hole. A telescopic member 294 is fixed to the valve body 291. The piston rod of the telescopic member 294 penetrates the valve cover 293 and is fixedly connected to the valve core 292. A sealing arrangement is provided between the piston rod of the telescopic member 294 and the valve cover 293.

[0043] In some examples, the hydraulic oil pump 28 and the oil tank 211 are both small devices, and the oil tank 211 can be a flexible bag, such as a rubber bag or a plastic bag. The hydraulic oil pump 28 and the oil tank 211 are both fixed to the inner side of the cylinder 221, and the input shaft of the hydraulic oil pump 28 is driven by the cylinder 221 through gears. A driving gear and a driven gear are arranged between the input shaft of the hydraulic oil pump 28 and the cylinder 221, and the diameter of the driven gear is smaller than the diameter of the driving gear, so that the input shaft of the hydraulic oil pump 28 can orbit around the center line of the cylinder 221 while rotating on its own center line, driving the hydraulic oil to run in the oil pipe.

[0044] In some examples, there are two flow control valves 29 and electromagnetic reversing valves 210, both of which are connected to the hydraulic oil pump 28, each flow control valve 29 is also connected to an electromagnetic reversing valve 210, each electromagnetic reversing valve 210 is also connected to two spaced swing driving members, and the two spaced swing driving members are connected in series. The speed and start and stop of the swing driving member can be controlled by controlling the flow control valve, and the direction of the swing driving member can be controlled by controlling the electromagnetic reversing valve 210, that is, the swing angle and swing direction of the grinding wheel 252 can be controlled by controlling the flow control valve 29 and the electromagnetic reversing valve 210. When the flow control valve 29 is in operation, the valve core 292 is a square structure adapted to the blind hole, and a sealing strip is provided on the side wall of the valve core 292. When the valve core 292 is at the top, the valve core 292 blocks an oil outlet and an oil inlet, and the hydraulic oil can only pass through the oil outlet and oil inlet at the bottom. At this time, the hydraulic oil flows back to the hydraulic pump and the oil tank through the flow control valve 29, and cannot work on the swing drive member 24. When the valve core 292 moves from the top to the bottom, the valve core 292 releases both oil outlets until the oil outlet and oil inlet at the bottom are blocked. At this time, the flow of hydraulic oil entering the swing drive member 24 can be controlled, and the output shaft of the swing drive member 24 can be driven to rotate, wherein the telescopic member 294 can be a stepper motor, the output shaft of the stepper motor passes through the valve cover 293, and the output shaft located below the valve cover 293 is provided with an external thread, and the valve core 292 is provided with a fixing nut, and the fixing nut is provided on the output shaft. When the stepper motor is running, the valve core 292 can be driven to reciprocate in the vertical direction.

[0045] In this embodiment, the swing drive member 24 is a hydraulic motor. The hydraulic motor models in this application are consistent. The input oil and output oil of the two spaced-apart hydraulic motors are in opposite directions.
