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 by 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 differences in cylindricity 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 rotating grinding discs to grind steel ingots, and control the rotation and displacement of steel ingots at the same time, so that the steel ingots can be fully ground. At the same time, there are also technical solutions for steel ingot grinding in the prior art. 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 erection and placement of die-cast steel ingots by setting up 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, when the steel ingot rotates, a rotating wheel is generally used to drive the steel ingot to rotate through friction. However, this rotation method cannot rotate based on the axis of the steel ingot when grinding the steel ingot with poor cylindricity, which results in the cylindricity of the steel ingot not increasing, thereby affecting the subsequent use effect 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, thereby causing damage to the grinding disc.

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 creative work are within the scope of protection of the present invention.

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

[0035] See also Figure 1 and Figure 4The support seat 3 is slidably connected to the upper side of the moving seat 2 front and back, and a supporting lower side plate 31 is installed at the bottom of the support seat 3. A bidirectional threaded rod 32 is penetrated through the moving seat 2 front and back. The supporting lower side plates 31 at the bottom of the two support seats 3 are connected to the threaded segments of the bidirectional threaded rod 32 by threaded cooperation. When supporting and transmitting steel ingots of different diameters, the transmission component 4 can increase the supporting stability and transmission stability of the steel ingot when it is in a suitable position. The present invention drives the two support seats 3 to move synchronously inward and outward by rotating the bidirectional threaded rod 32, and then adjusts the transmission component 4 to a suitable position to increase the stability of the support and transmission of the steel ingot.

[0036] See also Figure 3-Figure 5 The transmission component 4 includes a transmission support 42 installed on the top of the support seat 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 seat, and the output shaft of the rotating motor 43 is connected to one end of a rotating shaft 44 through a coupling, and the other end of the rotating shaft 44 is rotatably installed on the side of the other end of the transmission support 42, and transmission wheels 45 are evenly installed on the rotating shaft 44, and a fitting component 46 is distributed between every two transmission wheels 45, and the fitting component 46 is installed on the support seat 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 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, and through the telescopic movement of the top-extending elastic telescopic column 41, the transmission wheel 45 is always in contact with 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 be in contact with the side of the steel ingot, thereby further increasing the stability of the steel ingot during grinding.

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

[0038] It should be noted that the outer side of the fitting wheel 465 is provided with an anti-slip rubber layer to increase the fitting stability of the fitting wheel 465 to the side of the steel ingot. The outer side surface of the transmission wheel 45 is evenly provided with tooth structures. This arrangement can increase the stability of the transmission wheel 45 when driving the steel ingot to rotate.

[0039] See also Figure 3-Figure 4 The alignment component 6 includes an alignment support plate 61 slidably connected to the moving seat 2, a alignment block 62 is arranged in the middle of the alignment support plate 61, and a plurality of alignment connecting plates 63 are symmetrically installed on the side of the alignment block 62 away from the outer edge of the moving seat 2 with the center line of the alignment block 62 as the axis center, and a plurality of alignment connecting plates 63 are hinged on the opposite sides of each of the plurality of alignment connecting plates 63 with an alignment fitting plate 64, the alignment fitting plate 64 is an arc structure, and the sides of the alignment fitting plates 64 away from the alignment connecting plates 63 are evenly provided with balls 65; the alignment support plates 61 of the two alignment 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 alignment component 6 can not only It can position the left and right positions of the steel ingots, and can also align the rotating shaft positions of steel ingots of different diameters, so that the steel ingot with poor cylindricity can rotate with its rotating shaft 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 aligning support plates 61 are driven to approach synchronously through the synchronous position adjustment member 66, so that the aligning bonding plate 64 can be moved to the outside of the conical protrusion on the end face of the steel ingot, and the aligning bonding plate 64 is hinged on the aligning connecting plate 63, so that the aligning bonding plate 64 can stably fit on the side of the conical protrusion on the end face of the steel ingot, and the ball 65 on the aligning bonding plate 64 can not hinder its rotation when the steel ingot rotates.

[0040] See also 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 through the position adjustment 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 in the preset square through groove of 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 components are used to drive the positioning block 62 to adjust the height when the support seat 3 is adjusted in the front and rear positions; 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 end of 3 away from the support seat 3 passes through the hollow structure at the lower end of the correcting support plate 61, the linkage column 33 is located at the position of the hollow structure of the correcting support plate 61 and is hinged to the lower end of the lifting rod 34, and the upper end of the lifting rod 34 is hinged to the lower side of the follower connecting column 67. Specifically, when the support seat 3 is adjusted in the front and rear positions, the support seat 3 drives the linkage column 33 to move synchronously. When the 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 correcting block 62 is driven by the follower connecting column 67 to adjust. Therefore, the present invention only needs to adjust the position of the support seat 3 to synchronously adjust the height of the correcting 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 performs grinding processing on 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 performs grinding processing on 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 also 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 cross-arranged, and the two lifting rods 34 are hinged at the intersection. The hinged positions of the two lifting rods 34 are vertically slidably connected to the stabilizing connecting plate 68, and the hinged 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 lifting rods 34 arranged crosswise with each other in the present invention can be spliced ​​into a triangular structure, thereby increasing the stability of the linkage assembly.

[0043] See also Figure 2 and Fig. 9The supporting component 7 includes a hydraulic cylinder 71 installed at the external free end, a transmission plate 72 is installed at the telescopic end of the hydraulic cylinder 71, and a positioning support plate 73 is connected to the lower end of the transmission plate 72. 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 sides of the arc plate 75 are respectively connected to the grinding disc 5 and the pressure rod 76. 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 against 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 makes the side of the grinding disc 5 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 can drive the pressing elastic telescopic column 74 to contract when the pressing rod 76 contacts the protrusion of the steel ingot.

[0045] See also Fig. 9 , since the angle of the arc 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 line of the steel ingot is equal, the transmission plate 72 and the adjustment support plate 73 are hinged, and one side of the transmission plate 72 is connected to an angle adjustment stud 77 by threaded cooperation, and the lower end of the angle adjustment stud 77 is hinged to an angle connecting seat 78, and 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 line of the steel ingot is equal.

[0046] See also Figure 1-Figure 2In order to increase the accuracy of the angle adjustment of the adjustment support plate 73, the present invention adopts an indicator rod 79 to calibrate the angle adjustment of the adjustment support plate 73. A reference column 69 is provided on the side of the positioning block 62 close to the outer edge of the movable seat 2. The side of the adjustment support plate 73 is detachably installed with an L-shaped indicator rod 79. The transverse section of the indicator rod 79 is a length-adjustable structure. The angle of the adjustment support plate 73 can be intuitively adjusted by cooperating with the indicator rod 79 and the reference column 69. When the angle of the adjustment support plate 73 needs to be adjusted, the indicator rod 79 is inserted into the side of the adjustment support plate 73. By adjusting the angle of the adjustment support plate 73, the right end of the indicator rod 79 is directed to the reference column 69. At this time, the adjustment support plate 73 is adjusted to a suitable angle.
