Description

Technical Field

[0001] The invention relates to the technical field of steel ingot grinding, in particular to a large-scale steel ingot grinding machine. Background Art

[0002] Large steel ingots are steel columns formed through casting. The more common large steel ingots have cylindrical frustums at both ends. After the steel ingot is cast, its surface is relatively rough and there are cylindricity differences and protrusions in some parts. Therefore, in order to meet the needs of later processing, the steel ingot needs to be ground.

[0003] Existing large-scale steel ingot grinding machines generally use a rotating grinding disc to grind the steel ingots, while controlling the rotation and displacement of the steel ingots so that the steel ingots can be fully ground. At the same time, there are also technical solutions for steel ingot grinding in the existing technology. For example, the Chinese invention patent with publication number CN113953910A discloses a grinding device for die-cast steel ingots. This technical solution can ensure the placement of the die-cast steel ingots by setting a first storage table, a second storage table and a clamping platform, and the clamping platform can stably clamp the die-cast steel ingots, which can ensure that the grinder can stably grind the die-cast steel ingots and ensure the grinding effect. The flipping mobile vehicle can drive the die-cast steel ingots to move and transfer between the three, and can drive the die-cast steel ingots to flip in sequence. In conjunction with the clamping platform and the grinder, it can ensure the comprehensive grinding of the die-cast steel ingots.

[0004] Although the above technical solution can fully grind the steel ingot, the steel ingot is generally rotated by a rotating wheel through friction. However, this rotation method cannot be used as a reference for the rotation of the steel ingot with poor cylindricity, which results in the cylindricity of the steel ingot not being increased, thereby affecting the subsequent use of the steel ingot. At the same time, due to the large diameter deviation of different steel ingots, there is a risk of the steel ingot jumping or even slipping from the grinder when supporting and rotating the steel ingot. In addition, when the grinding disc is used to grind the steel ingot with protrusions, the side of the grinding disc will contact the protrusions of the steel ingot, which may cause damage to the grinding disc.

[0017] The beneficial effects of the present invention are: 1. The present invention can grind cylindrical steel ingots of different diameters and roughness, thereby increasing the applicability of the present invention. Moreover, before grinding the steel ingot, the present invention can use the conical protrusions at both ends of the steel ingot as a reference to limit the left and right positions of the steel ingot and lock the fixed axis, so that when the steel ingot rotates, it can rotate with its axis as the center of the circle, and the steel ingot can be ground with the grinding disc, thereby increasing the cylindricity of the ground steel ingot and facilitating the subsequent processing of the steel ingot.

[0018] 2. The present invention uses a rotating bidirectional threaded rod to drive the two support seats to move synchronously inward and outward, and then adjust the transmission components to a suitable position, so that the steel ingot can be stably placed on the transmission components, increasing the stability of the steel ingot support and transmission, and preventing the steel ingot from jumping or even sliding.

At the same time, when the roundness of the outer surface of the steel ingot is irregular, the transmission wheel can automatically retract and retract so that the axis of rotation of the steel ingot will not change significantly, thereby increasing the grinding effect of the steel ingot. Moreover, the telescopic movement of the elastic telescopic column allows the transmission wheel to always fit the side of the steel ingot, thereby increasing the transmission effect of the steel ingot.

The pressure rod provided in the present invention can move upward when it contacts the raised position of the steel ingot, causing the pressing elastic telescopic column to contract. At this time, the grinding disc will also move upward, so that the grinding disc always grinds the steel ingot with its outer ring surface, preventing the side of the grinding disc from contacting the raised position of the steel ingot and causing damage to it.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See Figure 1-Figure 2 A large steel ingot grinding machine includes a base plate 1, a movable base 2 is installed on the upper side of the base plate 1 through an electric slider 11, two support bases 3 are connected to the upper side of the movable base 2, and a transmission component 4 is connected to each support base 3. A grinding disc 5 is distributed on the upper rear side of the movable base 2, and a positioning component 6 for limiting the position of the steel ingot is slidably connected to the left and right ends of the top of the movable base 2. The grinding disc 5 is installed on the lower side of the support component 7, and the support component 7 is installed at the free end of the outside. The present invention can grind cylindrical steel ingots of different diameters and roughness, increasing the applicability of the present invention. Specifically, the steel ingot is first lifted between the transmission components 4 on the two support seats 3, and the position of the steel ingot can be corrected by the positioning component 6 so that the steel ingot has no left or right position deviation. At the same time, the positioning component 6 can also perform an axial centering operation on the steel ingot to increase the cylindricity of the steel ingot after grinding. The position of the grinding disk 5 is then adjusted by the support component 7 so that the grinding disk 5 can grind the surface of the steel ingot. Finally, the electric slider 11 drives the movable seat 2 to perform left and right reciprocating motion and cooperates with the transmission component 4 to drive the steel ingot to rotate, so that the steel ingot is fully ground.

[0035] See Figure 1 and Figure 4The support seat 3 is connected to the upper side of the movable seat 2 by sliding forward and backward. The bottom of the support seat 3 is installed with a support lower side plate 31. The movable seat 2 is penetrated by a two-way threaded rod 32 in the front and rear. The support lower side plates 31 at the bottom of the two support seats 3 are connected to the threaded segments of the two-way threaded rod 32 by threaded cooperation. When supporting and transmitting steel ingots of different diameters, when the transmission component 4 is in a suitable position, the support stability and transmission stability of the steel ingot can be increased. The present invention drives the two support seats 3 to move synchronously inward and outward by rotating the two-way threaded rod 32, and then adjusts the transmission component 4 to a suitable position to increase the stability of the steel ingot support and transmission.

[0036] See Figure 3-Figure 5 The transmission component 4 includes a transmission support 42 installed on the top of the support base 3 through an extended elastic telescopic column 41. A rotating motor 43 is installed on one end of the upper part of the transmission support 42 through a motor base. The output shaft of the rotating motor 43 is connected to one end of a rotating shaft 44 through a coupling. The other end of the rotating shaft 44 is rotatably installed on the side of the other end of the transmission support 42. Transmission wheels 45 are evenly installed on the rotating shaft 44. There is a fitting component 46 distributed between every two transmission wheels 45. The fitting component 46 is installed on the support base 3. The transmission component 4 is used to drive the steel ingot placed thereon to rotate so that the steel ingot can be fully ground. At the same time, when the roundness of the outer surface of the steel ingot is irregular, the transmission wheel 45 Driven by the elastic telescopic column 41, it can automatically extend and retract, so that the axis of rotation of the steel ingot will not change significantly, thereby increasing the grinding effect of the steel ingot, and the telescopic movement of the top-extending elastic telescopic column 41 allows the transmission wheel 45 to always fit the side of the steel ingot, thereby increasing the transmission effect of the steel ingot. Specifically, when the steel ingot is placed on the two transmission components 4, the weight of the steel ingot can drive the top-extending elastic telescopic column 41 to contract to a certain extent. When the steel ingot is ground, the rotation of the rotating motor 43 drives the transmission wheel 45 to rotate synchronously, and the transmission wheels 45 on the front and rear sides drive the steel ingot to rotate from front to back. The fitting component 46 can always fit the side of the steel ingot, further increasing the stability of the steel ingot during grinding.

[0037] See Figure 5-Figure 6The fitting component 46 includes a fitting bracket 461 installed on the support seat 3, and a fitting elastic column 462 is connected to the fitting bracket 461. The end of the fitting elastic column 462 is installed with an extrusion fitting plate 463, and a V-shaped wheel frame 464 is hingedly installed on the extrusion fitting plate 463, and a fitting wheel 465 is installed at both ends of the V-shaped wheel frame 464; the extrusion fitting plate 463 is arranged at an angle, and the fitting component 46 is used to fit on the side of the steel ingot to increase the stability of the steel ingot during rotation. Specifically, when the steel ingot is placed between the transmission wheels 45 on the two transmission components 4, the extrusion fitting plate 463, under the action of the fitting elastic column 462, makes the fitting wheel 465 fit on the side of the steel ingot, and the V-shaped wheel frame 464, under the action of the hinge, makes the fitting wheel 465 able to fit on the side of the steel ingot with different diameters.

[0038] It should be noted that the outer side of the bonding wheel 465 is provided with a non-slip rubber layer to increase the bonding stability of the bonding wheel 465 to the side of the steel ingot. The outer side surface of the transmission wheel 45 is evenly provided with a tooth structure. This setting can increase the stability of the transmission wheel 45 when driving the steel ingot to rotate.

[0039] See Figure 3-Figure 4 The positive component 6 includes a positive support plate 61 slidably connected to the moving seat 2, and a positive block 62 is provided in the middle of the positive support plate 61. The side of the positive block 62 away from the outer edge of the moving seat 2 is symmetrically installed with a plurality of positive connecting plates 63 with the center line of the positive block 62 as the axis center. The opposite sides of the plurality of positive connecting plates 63 are hinged with a positive bonding plate 64. The positive bonding plate 64 is an arc structure, and the side of the positive bonding plate 64 away from the positive connecting plate 63 is evenly provided with balls 65; the positive support plates 61 of the two positive components 6 are connected by a synchronous position adjusting member 66 installed in the middle of the moving seat 2. In this embodiment, the synchronous position adjusting member 66 adopts a bidirectional electric push rod, and the positive component 6 can not only It can position the left and right positions of the steel ingot, and can also align the rotation axis positions of steel ingots of different diameters, so that the steel ingot with poor cylindricity can be rotated with its rotation axis as the axis, thereby increasing the effect of steel ingot grinding. Specifically, after the steel ingot is placed on the transmission wheel 45, the two alignment support plates 61 are driven to approach synchronously through the synchronous position adjustment member 66, so that the alignment bonding plate 64 can be moved to the outside of the cone-shaped protrusion on the end face of the steel ingot, and the alignment bonding plate 64 is hinged on the alignment connecting plate 63, so that the alignment bonding plate 64 can be stably attached to the side of the cone-shaped protrusion on the end face of the steel ingot, and the ball 65 on the alignment bonding plate 64 can not hinder its rotation when the steel ingot rotates.

[0040] See Figure 3 、 Figure 7-Figure 8Since the axial position of steel ingots with different diameters will change, the present invention adopts a method of synchronously driving the positioning block 62 to adjust the height by adjusting the position of the support seat 3, thereby increasing the efficiency and accuracy of the positioning component 6 in adjusting the fixed axis of the steel ingot. The positioning block 62 is vertically slidably connected to the square through groove preset in the positioning support plate 61. The lower side of the positioning support plate 61 is a hollow structure. A follow-up connecting column 67 is installed at the bottom of the positioning block 62. The lower end of the follow-up connecting column 67 extends into the hollow structure of the positioning support plate 61. The opposite sides of the two support seats 3 are evenly provided with linkage components. The linkage component is used to drive the positioning block 62 to adjust its height when the support seat 3 is adjusted forward and backward; the linkage component includes a linkage column 33 that is slidably connected to the side of the support seat 3 along the length direction of the support seat 3. The linkage columns 33 on the two linkage components are staggered left and right. The linkage column 3 When the two linkage columns 33 on the two support seats 3 move away from each other, the lifting rod 34 can drive the follower connecting column 67 to move upward. When the linkage columns 33 on the two support seats 3 move toward each other, the lifting rod 34 can drive the follower connecting column 67 to move downward, and then the height of the positioning block 62 is adjusted by the follower connecting column 67. Therefore, the present invention only needs to adjust the position of the support seat 3 to synchronize the height of the positioning block 62, thereby increasing the efficiency and accuracy of the fixed axis operation of the steel ingot.

[0041] It can be understood that when the present invention is used to grind steel ingots with larger diameters, the support seat 3 needs to move outward, and the axial position of the steel ingots with larger diameters is higher, so the positioning block 62 can move upward synchronously. When the present invention is used to grind steel ingots with smaller diameters, the support seat 3 needs to move inward, and the axial position of the steel ingots with smaller diameters is lower, so the positioning block 62 can move downward synchronously.

[0042] See Figure 8 Due to the heavy weight of the steel ingot, the linkage assembly needs to withstand greater pressure. A stabilizing connecting plate 68 is installed on the lower side of the middle part of the follower connecting column 67. The lifting rods 34 on the two linkage assemblies are arranged crosswise, and the two lifting rods 34 are hinged at the intersection. The hinge positions of the two lifting rods 34 are vertically slidably connected to the stabilizing connecting plate 68, and the hinge positions of the upper ends of the two lifting rods 34 are slidably connected to the lower side of the follower connecting column 67 front and back. The present invention adopts the lifting rods 34 arranged crosswise with each other to be spliced into a triangular structure, thereby increasing the stability of the linkage assembly.

[0043] See Figure 2 and Figure 9The supporting component 7 includes a hydraulic cylinder 71 installed at the external free end, and a transmission plate 72 is installed at the telescopic end of the hydraulic cylinder 71. The lower end of the transmission plate 72 is connected to a positioning support plate 73. The lower side of the positioning support plate 73 is connected to an arc plate 75 by pressing an elastic telescopic column 74. The lower side of the arc plate 75 is connected to the grinding disc 5 and the pressure rod 76 respectively. The supporting component 7 is used to support the grinding disc 5 and adjust the position and angle of the grinding disc 5 so that the grinding disc 5 can grind the steel ingot. Specifically, when the positioning of the steel ingot is completed, the hydraulic cylinder 71 is extended so that the grinding disc 5 is tightly attached to the outer side of the steel ingot. At this time, the pressure rod 76 also presses against the outer side of the steel ingot. Then the grinding disc 5 is controlled to rotate and move left and right so that the steel ingot can be fully ground. When there is a protrusion at a certain position of the steel ingot, the grinding disc 5 directly contacts it, which causes the side of the grinding disc 5 to press against the protruding position of the steel ingot. In this case, the grinding efficiency of the steel ingot is low and the grinding disc 5 may be damaged. The pressure rod 76 provided in the present invention can move upward when it contacts the protruding position of the steel ingot, causing the elastic telescopic column 74 to contract. At this time, the grinding disc 5 will also move upward, so that the grinding disc 5 always grinds the steel ingot with its outer ring surface.

[0044] It should be noted that the lower end of the pressing rod 76 is a spherical structure, which enables the pressing rod 76 to drive the elastic telescopic column 74 to contract when it contacts the protrusion of the steel ingot.

[0045] See Figure 9 The angle of the curved plate 75 needs to be adjusted when the diameter of the steel ingot that needs to be corrected changes, so that the distance between the grinding disc 5 and the pressure rod 76 and the axis of the steel ingot is equal. The transmission plate 72 and the adjustment support plate 73 are hinged. One side of the transmission plate 72 is connected to an angle adjustment stud 77 by threaded fitting. The lower end of the angle adjustment stud 77 is hinged to an angle connecting seat 78. The lower end of the angle connecting seat 78 is slidably connected to the adjustment support plate 73. By rotating the angle adjustment stud 77, the adjustment support plate 73 can be driven to rotate at an angle, so that the distance between the grinding disc 5 and the pressure rod 76 and the axis of the steel ingot is equal.

[0046] See Figure 1-Figure 2The cam 79 is engaged with the cam 79 to adjust the angle of the support plate 73 so that the cam 79 is in the correct position and the cam 79 is in the correct position.

[0047] While 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 alterations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
