The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0024] The utility model will be further described in conjunction with the drawings and specific embodiments.
[0025] Referring to Figures 1 to 6 The embodiment provides a steel plate centering device for centering the steel plate in the production of medium plate stainless steel, so as to ensure that the steel plate can be properly centered, and the center line of the steel plate coincides with or is parallel to the center line of the equipment, that is, the steel plate enters the feeding port of the equipment, such as a solid melting furnace, a straightening machine, a shot blasting machine, etc., in a relatively strict conveying position.
[0026] As Figure 1 The steel plate centering device of the embodiment comprises a roller 1 for conveying the steel plate, two centering mechanisms 2 and eight steel plate lifting mechanisms 3 matched with the centering mechanisms 2, and the two centering mechanisms 2 are arranged in sequence along the conveying direction of the roller 1 and are spaced apart from each other.
[0027] As Figure 2 and Figure 5 The centering mechanism 2 comprises a first driver 21, a rack 22, a gear 23, a fixed frame 24, a movable frame 25 movably arranged, and a centering push plate 26 fixed to the movable frame 25, the gear 23 is rotatably assembled to the fixed frame 24, the movable frame 25 is assembled with the rack 22, and the rack 22 is engaged with the gear 23.
[0028] As Figure 1 , Figure 3 and Figure 4 The steel plate lifting mechanism 3 comprises a hinge base 32, a second driver 33, and a swingable lifting arm 31, one end of the lifting arm 31 is rotatably connected to the hinge base 32, the other end of the lifting arm 31 is connected to the second driver 33, each lifting arm 31 is provided with a plurality of rollers 311 for supporting the steel plate, and under the driving of the second driver 33, the lifting arm 31 assembled with the rollers 311 can swing up and down around the hinge base 32.
[0029] When lifting the steel plate, the arrangement direction of the rollers 311 on the lifting arm 31 is parallel to the roller bed surface of the roller bed 1, and the lifting arm 31 swings upward and passes through the space between the conveying rollers of the roller bed 1, so as to lift the steel plate on the roller bed 1 away from the roller bed surface of the roller bed 1, and then the first driver 21 drives the movable frame 25 and the centering push plate 26 to move toward the steel plate, and pushes the steel plate, so as to adjust the conveying position of the steel plate on the roller bed 1, at this time, the activity track of the centering push plate 26 is perpendicular to the conveying direction of the roller bed 1.
[0030] When the steel plate is centered, the steel plate moves on the rollers 311, and the pure rolling rollers 311 ensure that the steel plate will not be scratched. After the centering of the steel plate is completed, the lifting arm 31 swings downward, and the steel plate falls back until it contacts the roller bed surface of the roller bed 1, at this time, the lifting arm 31 is below the roller bed surface of the roller bed 1.
[0031] In the embodiment, the number of the first driver 21, the rack 22, the gear 23 and the fixed frame 24 of each centering mechanism 2 is respectively 4, the number of the movable frame 25 and the centering push plate 26 of each centering mechanism 2 is respectively two, and the two centering push plates 26 of the same centering mechanism 2 are respectively symmetrically distributed on the two sides of the roller bed 1 perpendicular to the conveying direction thereof, specifically, the first driver 21 is a first hydraulic cylinder, the second driver 33 is a second hydraulic cylinder, and as shown in the figure, the two same-side gears 23 of each centering mechanism 2 are mechanically synchronized through the shaft coupling 4. Figure 1
[0032] When it is necessary to center the steel plate on the roller bed 1, the lifting arm 31 which can swing in the steel plate lifting mechanism 3 is used to lift the steel plate on the roller bed 1 away from the roller bed surface of the roller bed 1, and then the centering mechanism 2 is used to make the centering push plate 26 push the steel plate to move on the lifting arm 31, that is, to adjust the conveying position of the steel plate on the roller bed 1, so as to realize the centering of the steel plate and meet the relatively strict conveying position requirement.
[0033] In another preferred embodiment, as shown in the figure, three adjacent lifting arms 31 on the same side are integrally connected through the cross beam 341 to form a lifting arm unit 34, and one second driver 33 corresponds to one lifting arm unit 34. Figure 3
[0034] In the specific embodiment, the first driver 21 is connected to the movable frame 25 through a pin shaft, and the rack 22 is bolted to the movable frame 25.
[0035] The lifting arms 31 are evenly arranged in the middle of the roller bed 1, and the distance between the lifting arms 31 of the same lifting arm unit 34 is 1 m.
[0036] When the hot steel plate arrives at the preset position, the cold-hot metal detector on the roller bed 1 detects the arrival of the steel plate at the preset position and sends a signal to the control system of the steel plate centering device of the embodiment, and the roller bed 1 stops rotating, and the steel plate stops at the preset position. At this time, according to the length of the steel plate, two centering mechanisms 2 can be used simultaneously to center the steel plate, or one centering mechanism 2 can be used alone to center the steel plate.
[0037] When the steel plate arrives at the preset position, the cold-hot metal detector on the roller bed 1 detects the arrival of the steel plate at the preset position and sends a signal to the control system of the steel plate centering device of the embodiment, and the roller bed 1 stops rotating, and the steel plate stops at the preset position. At this time, according to the length of the steel plate, two centering mechanisms 2 can be used simultaneously to center the steel plate, or one centering mechanism 2 can be used alone to center the steel plate.
[0038] When the cylinder rod of the second driver 33 extends to the maximum position, the lifting arm 31 is in a horizontal state.
[0039] When the cylinder rod of the second driver 33 retracts, the lifting arm 31 falls and all the lifting arms 31 are hidden below the roller bed surface of the roller bed 1.
[0040] In addition, when receiving the centering signal of the control system, the first driver 21 drives the centering push plate 26 to move from both sides of the roller bed 1 to the center of the roller bed 1, and the moving speed can be set according to the specific site, and the moving distance is controlled by the displacement sensor built in the first driver 21.
[0041] The steel plate centering device of the embodiment can set the opening degree according to the actual width, plate shape and other parameters of the current steel plate in the control system, and the adjustment of the opening degree is performed by the first driver 21.
[0042] Each steel plate lifting mechanism 3 is independent of each other, and the number of steel plate lifting mechanisms 3 put into use can be automatically selected according to the plate length data of the steel plate in the control system during production, so as to improve the production efficiency.
[0043] Further preferably, as shown in Figure 5 and Figure 6 The movable frame 25 is provided with two pressure wheels 251 and four side guide wheels 252, and the two side guide wheels 252 are respectively distributed on both sides of the movable frame 25 to ensure the stability of the movement of the movable frame 25 during centering.
[0044] Further preferably, as shown in Figure 4 The steel plate lifting mechanism 3 further comprises a cooling pipeline 36 for cooling the lifting arm 31, and the cooling pipeline 36 is provided with an adjusting valve 37.
[0045] In order to prevent the deformation of the lifting arm 31 during the centering of the hot steel plate, the lifting arm 31 is made into a welded structure, and the cooling pipeline 36 is supplied with cooling water, and the cooling water is circulated, that is, the cooling water enters one end of the lifting arm 31, circulates in the lifting arm 31 for one round and then flows out, so as to achieve the cooling effect.
[0046] Since the lifting arm 31 is movable, a hose is used to flexibly connect the cooling pipe 36 on the lifting arm 31 with the main water pipe, and the water flow is adjusted by adjusting the opening of the regulating valve 37 to achieve the best cooling effect.
[0047] Further preferably, as shown in Figure 3 and Figure 4 The steel plate lifting mechanism 3 further comprises a guide assembly 35 for guiding the lifting of the lifting arm unit 34, and the guide assembly 35 and the second driver 33 are respectively located outside the roller table 1.
[0048] The guide assembly 35 comprises a guide plate and a copper sliding plate, and the guide plate is arranged on the cross beam 341 and cooperates with the copper sliding plate filled with lubricating oil to reduce the resistance when the lifting arm unit 34 is lifted.
[0049] When the hot steel plate is centered, since the lifting arm 31 is cooled by cooling water, the roller table 1 is usually in a high-temperature and humid environment, and the second driver 33 and the guide assembly 35 are arranged outside the roller table 1, so that it is not necessary to operate under the roller table 1 during maintenance, the safety of personnel and equipment is greatly improved, the convenience of maintenance is realized, and the service life of the above-mentioned equipment is improved.
[0050] The embodiment adopts a combined arrangement, has a large centering length range, is driven by a hydraulic cylinder, is simple and convenient to operate and maintain, and adopts a transmission structure composed of the gear 23 and the rack 22, so that the steel plate can be kept stable and fast during centering.
[0051] Although the utility model is specifically shown and introduced in combination with the preferred embodiment, it should be understood by those skilled in the art that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all changes are within the protection scope of the utility model.
