Description

Technical Field

[0001] This utility model belongs to the field of metal straightening technology, specifically relating to a bottom sealing plate flatness correction device. Background Technology

[0002] A bottom sealing plate is a covering component installed at the bottom of equipment, enclosure, or structure. It is mainly used to seal bottom gaps, protect internal components, or enhance the stability of the overall structure. A flatness correction device is a special device used to adjust and correct the flatness of the bottom sealing plate. Its core function is to apply progressive pressure through upper and lower staggered rollers to correct uneven sealing plates, eliminate their internal stress, and ensure that they meet the flatness standards required by the design.

[0003] The existing bottom sealing plate flatness correction device requires the operator to manually push the sealing plate between the upper and lower rollers. However, due to the lack of feeding constraint limit and the positioning deviation during manual operation, the sealing plate is prone to enter the roller at an inclined angle. The contact pressure between the edge of the sealing plate and the roller surface will change, resulting in a greater amount of pressure on local areas (such as the side that contacts first), causing over-correction at the edge or under-correction in the middle, which affects the correction quality. Utility Model Content

[0004] The purpose of this utility model is to provide a bottom sealing plate flatness correction device. The device uses two adjustable limiting plates and rollers to form a three-sided limiting of the sealing plate, which can be adapted to constrain sealing plates of different widths, eliminate positioning deviations caused by manual operation, and keep the sealing plate in the positive angle during feeding, thus avoiding correction defects caused by tilted feeding.

[0005] The specific technical solution adopted by this utility model is as follows: A bottom sealing plate flatness correction device includes a frame, with mounting plates symmetrically fixed on the top of the frame. Two sets of rollers are driven between the two mounting plates. A limiting plate is symmetrically slidable on one side of the mounting plate in the horizontal direction. A roller is rotatably connected between the two mounting plates. The outer circumference generatrix of the roller is coplanar with the top surface of the lower roller of the roller set. A manual spinning mechanism is provided on the top of the limiting plate for fixing or releasing the horizontal displacement constraint of the limiting plate.

[0006] The mounting plate has a pair of guide rods fixedly connected to its ends, and the limiting plate has a sliding fit with the corresponding guide rods through through holes at both ends.

[0007] The roller is positioned between the two guide rods, and the limiting plate slides into the roller through a through hole in the plate.

[0008] The diameter of the second through hole is larger than the diameter of the roller, forming a preset gap.

[0009] The manual spinning mechanism includes an adjusting screw threadedly connected to the limiting plate, and the limiting plate has a vertical groove inside.

[0010] A connecting block is slidably fitted inside the vertical groove, and the end of the adjusting screw is rotatably connected to the connecting block.

[0011] A clamping block is fixedly connected to the bottom of the connecting block. The side of the clamping block facing the guide rod is formed with an arc-shaped concave surface, and the radius of curvature of the arc-shaped concave surface is equal to the outer diameter of the guide rod.

[0012] The technical effect achieved by this utility model is as follows: by using two adjustable limiting plates in conjunction with rollers to form three-sided limiting of the sealing plate, it can adapt to and constrain sealing plates of different widths, eliminate positioning deviations caused by manual operation, and keep the sealing plate in the positive angle during feeding, thus avoiding correction defects caused by tilted feeding.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-2As shown, a bottom sealing plate flatness correction device includes a frame 1. Mounting plates 101 are symmetrically fixed on the top of the frame 1. Two sets of rollers 102 are driven between the two mounting plates 101. A limiting plate 105 is symmetrically slidably provided on one side of the mounting plate 101 in the horizontal direction. A pair of guide rods 103 are fixedly connected to the ends of the mounting plates 101. The limiting plate 105 forms a sliding fit with the corresponding guide rod 103 through through holes 106 opened at both ends.

[0017] According to the above structure, the upper and lower roller sets 102 can be rotated by the motor drive to perform roll pressing correction on the sealing plate passing through the gap between the two roller sets 102. The limiting plate 105 forms a horizontal sliding fit with the corresponding guide rod 103 through the through hole 106. By adjusting the position of the limiting plate 105, the distance between the two limiting plates 105 can be shortened or widened to adapt to sealing plates of different widths, forming limiting constraints on both sides of the sealing plate, so that the sealing plate maintains a positive angle when entering the roller set 102.

[0018] See attached document Figure 2-3 The top of the limiting plate 105 is provided with a manual spinning mechanism for fixing or releasing the horizontal displacement constraint of the limiting plate 105. The manual spinning mechanism includes an adjusting screw 108 threadedly connected to the limiting plate 105. A vertical groove 111 is opened inside the limiting plate 105. A connecting block 109 is slidably fitted in the vertical groove 111. The end of the adjusting screw 108 is rotatably connected to the connecting block 109. A pressing block 110 is fixedly connected to the bottom of the connecting block 109. The side of the pressing block 110 facing the guide rod 103 is formed with an arc-shaped concave surface. The radius of curvature of the arc-shaped concave surface is equal to the outer diameter of the guide rod 103.

[0019] According to the above structure, the connecting block 109 can slide vertically in the vertical groove 111. When the adjusting screw 108 is rotated, it generates axial displacement through its own threaded engagement with the top of the limiting plate 105, thereby driving the connecting block 109 to move up and down. When the connecting block 109 moves, it can drive the pressing block 110 to fit against or move away from the guide rod 103. The pressing block 110 is made of flexible material, such as rubber or silicone, to enhance the friction with the guide rod 103. When the pressing block 110 is tightly fitted with the guide rod 103 under the axial pressure of the adjusting screw 108, it forms an anchoring effect on the limiting plate 105, thereby fixing its position. Conversely, when the pressing block 110 is not fitted with the guide rod 103, the position of the limiting plate 105 can be adjusted by sliding along the guide rod 103.

[0020] See attached document Figure 1-2A roller 104 is rotatably connected between the two mounting plates 101. The roller 104 is located between the two guide rods 103, and the limiting plate 105 forms a sliding fit with the roller 104 through a through hole 107. The diameter of the through hole 107 is larger than the diameter of the roller 104, forming a preset gap. The outer circumference generatrix of the roller 104 is coplanar with the top surface of the lower roller of the roller assembly 102.

[0021] According to the above structure, since there is a preset gap between the through hole 107 and the roller 104, the limiting plate 105 will not rub against the roller 104 when it moves, and the roller 104 can also rotate without resistance. The roller 104 is located on one side of the roller group 102, and its outer circumference generatrix is ​​coplanar with the top surface of the roller group 102 below, that is, another horizontal support point is formed on one side of the roller group 102. The sealing plate can be placed on the roller 104 and then pushed between the two roller groups 102 to keep the feeding stable. The rotatable characteristic of the roller 104 can also reduce the friction of the feeding.

[0022] The working principle of this utility model is as follows: the upper and lower roller groups 102 are rotated by the power of the motor, which can perform roller pressing and correction operations on the sealing plate passing through the gap between the two roller groups 102. The limiting plate 105 forms a horizontal sliding fit relationship with the corresponding guide rod 103 through the through hole 106 on it. By adjusting the position of the limiting plate 105, the distance between the two limiting plates 105 can be reduced or expanded, thereby adapting to sealing plates of different widths and forming effective limiting constraints on both sides of the sealing plate, so as to ensure that the angle of the sealing plate remains positive when it enters the roller group 102. Furthermore, the connecting block 109 can slide vertically within the vertical groove 111. When the adjusting screw 108 is rotated, due to the threaded engagement between it and the top of the limiting plate 105, axial displacement will occur, thereby driving the connecting block 109 to move up and down. As the connecting block 109 moves, it will cause the pressing block 110 to adhere to or move away from the guide rod 103. The pressing block 110 is made of flexible materials such as rubber and silicone, which can effectively enhance the friction between it and the guide rod 103. Furthermore, when the clamping block 110 is subjected to the axial pressure of the adjusting screw 108 and is in close contact with the guide rod 103, it will anchor the limiting plate 105 and fix its position; conversely, when the clamping block 110 is not in contact with the guide rod 103, the limiting plate 105 can slide along the guide rod 103 to adjust its position. Furthermore, since a certain preset gap is reserved between the through hole 107 and the roller 104, the limiting plate 105 will not rub against the roller 104 during movement. At the same time, the roller 104 can also rotate without resistance. The roller 104 is located on one side of the roller group 102, and its outer circumference generatrix is ​​on the same plane as the top surface of the roller group 102 below. This is equivalent to forming another horizontal support point on one side of the roller group 102. During operation, the sealing plate can be placed on the roller 104 and then pushed between the two roller groups 102. This can ensure the stability of feeding and reduce the friction during feeding by taking advantage of the rotatable characteristic of the roller 104.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
