Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing equipment, in particular to a rib plate leveling device. Background Technique

[0002] At present, in steel structure processing plants, a large number of rib plates are used in the process of manufacturing steel components. Most of the rib plates are sheared from steel coils on the slitting line. After the rib plates are sheared, they are easy to deform. If the rib plates are not flat, they need to be leveled. Traditionally, workers mostly use a sledgehammer for manual leveling. This method has a large labor intensity, low efficiency and it is difficult to grasp the flatness.

[0003] The utility model with the publication number of CN211990333U proposes a rib plate leveling device, which has a platform support. Two parallel active leveling rollers are arranged on the platform support. The two active leveling rollers are arranged on the same horizontal plane and are driven to rotate synchronously by a set of chain drive devices. A passive leveling roller is also arranged above the two active leveling rollers. Both ends of the passive leveling roller are supported and suspended by a set of height adjustment mechanisms respectively; there is also a leveling rib plate collection box, and the leveling rib plate collection box is docked below the output port of the active leveling roller; this leveling device is very simple for workers to operate and is also very convenient to adjust. It can be adjusted according to different rib plate thicknesses, and is simple and reliable.

[0004] However, the above-mentioned existing technology still has the following deficiencies when in use: the distance between the active leveling roller and the passive leveling roller is adjusted by the height adjustment mechanism. The height adjustment mechanism is provided with screws for adjusting the height, and there are many involved screws. Since the passive leveling roller is relatively heavy, and when adjusting the height, the upper and lower nuts on the screws need to be screwed one by one, which is not only laborious but also has low adjustment efficiency.

[0005] Therefore, the utility model provides a rib plate leveling device. Content of the Utility Model

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a rib plate leveling device to solve the problems raised in the above background technique. The utility model has the advantages of being more convenient, faster and labor-saving for switching and leveling rib plates of various common thicknesses.

[0007] In order to achieve the above purpose, the utility model is realized by the following technical solutions: a rib plate leveling device, including a support platform and two supporting cylinders. Two vertical plates are fixedly connected to the top of the support platform. The two supporting cylinders are rotatably connected between the two vertical plates. A rotating shaft located above the supporting cylinders is rotatably connected between the two vertical plates. The outer circumference of the rotating shaft is provided with rotating rollers evenly distributed circumferentially. Pressing cylinders with different outer diameters are respectively sleeved on the rotating rollers evenly distributed axially.

[0008] Further, a bearing sleeve sleeving the outer part of the rotating shaft is welded on the vertical plate. Insertion holes are formed through the outer part of the bearing sleeve, and positioning holes which are circumferentially and uniformly distributed and are connected with the insertion holes through pins are formed on the outer peripheral wall of the rotating shaft.

[0009] Further, positioning discs are fixedly sleeved on the outer peripheral wall of the rotating shaft near both ends, and support sleeves which are rotationally connected with the ends of the roller are welded on the disc surfaces of the positioning discs.

[0010] Further, a coaxial bearing shaft is fixedly arranged in the middle of the supporting cylinder, and positioning sleeves which are rotationally matched with the bearing shaft are welded on the two vertical plates.

[0011] Further, a horizontally distributed rack is slidably connected to the outer side of the vertical plate. Gears which are meshed with the rack are fixedly connected to both ends of the rotating shaft, and a control oil cylinder is fixedly connected to one side of the vertical plate. One end of the control oil cylinder is fixedly connected to one end of the rack.

[0012] Further, a guide block is welded on one side of the vertical plate, and a guide groove which is slidably matched with the guide block is formed through one side of the rack.

[0013] Further, a handle rod is welded on the outer peripheral wall of the rotating shaft at the end.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. In the utility model, a rotating shaft is arranged, and a plurality of rollers are circumferentially arranged around the rotating shaft. A pressing cylinder is sleeved on the roller, and the outer diameters of the pressing cylinders corresponding to the plurality of rollers are different. Therefore, when leveling rib plates with different thicknesses is required, only by rotating the rotating shaft can one of the pressing cylinders be driven to be in the leveling station, which has the advantage that the operation of switching to level rib plates with different thicknesses is more convenient compared with the prior art.

[0016] 2. In the utility model, by arranging a rack, a gear and a control oil cylinder, the control drives the two supporting cylinders to rotate through the cooperation of the rack and the gear. This kind of arrangement has the advantage that the leveling driving force is stronger compared with the structure adopting chain drive in the prior art, and the efficiency of the leveling process is greatly improved.

Specific implementation manner

[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0022] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a rib plate leveling device, including a support platform 1 and two support cylinders 2. Two vertical plates 3 are fixedly connected to the top of the support platform 1. The two support cylinders 2 are rotatably connected between the two vertical plates 3. Preferably, during specific implementation, a coaxial bearing shaft 21 is fixedly arranged in the middle of the support cylinder 2, and a positioning sleeve 32 that rotates in cooperation with the bearing shaft 21 is welded on the two vertical plates 3. A rotating shaft 4 located above the support cylinder 2 is rotatably connected between the two vertical plates 3. A circumferentially evenly distributed rotating roller 5 is arranged around the outer periphery of the rotating shaft 4. Preferably, during specific implementation, positioning disks 42 are fixedly sleeved on the outer peripheral wall of the rotating shaft 4 near both ends, and support sleeves 421 that rotate in connection with the ends of the rotating rollers 5 are welded on the disk surfaces of the positioning disks 42. Pressing cylinders 6 with different outer diameters are respectively sleeved on the axially evenly distributed rotating rollers 5. That is to say, when the rotating shaft 4 rotates, the pressing cylinders 6 with different outer diameters will be located above the two support cylinders 2. At this time, the pressing cylinders 6 are in the leveling station, and the distances between the pressing cylinders 6 in the leveling station and the two support cylinders 2 are the same as the thickness of the rib plate. Therefore, by rotating the rotating shaft 4, rib plates with different thicknesses can be leveled.

[0023] Furthermore, a bearing sleeve 31 sleeved on the outside of the rotating shaft 4 is welded on the vertical plate 3. A jack 311 is penetrated and opened on the outside of the bearing sleeve 31. Positioning holes 41 that are circumferentially evenly distributed and are connected to the jack 311 by pins are opened on the outer peripheral wall of the rotating shaft 4. The number of the positioning holes 41 is the same as the number of the rotating rollers 5. When the pin is inserted into a positioning hole 41 on the rotating shaft 4, the rotating shaft 4 is locked.

[0024] Among them, a handle bar 43 is welded on the outer peripheral wall of the rotating shaft 4 at the end. The handle bar 43 is a hand-held component, and the rotating shaft 4 can be easily rotated by holding the handle bar 43.

[0025] In this embodiment, a horizontally distributed rack 7 is slidably connected to the outer side of the vertical plate 3. Both ends of the rotating shaft 4 are fixedly connected with gears 8 meshing with the rack 7. One side of the vertical plate 3 is fixedly connected with a control oil cylinder 9. One end of the control oil cylinder 9 is fixedly connected with one end of the rack 7. The control oil cylinder 9 provides driving force for the sliding of the rack 7. The rack 7 drives the gear 8 to rotate through meshing, and then can drive the two supporting cylinders 2 to rotate synchronously and in the same direction.

[0026] Further, a guide block 33 is welded to one side of the vertical plate 3. A guide groove 71 for sliding fit with the guide block 33 is formed through one side of the rack 7. This setting can improve the sliding stability of the rack 7.

[0027] Working principle: When it is necessary to flatten rib plates of different thicknesses, manually pull out the pin from the positioning hole 41 and the jack hole 311, then hold the handle 43 and rotate it to lower a suitable pressing cylinder 6 above the middle of the two supporting cylinders 2, and then reset the pin. At this time, the rotating shaft 4 is locked. Then insert the rib plate to be flattened into the space between the supporting cylinder 2 and the pressing cylinder 6. Start the control oil cylinder 9. The control oil cylinder 9 acts to drive the rack 7 to move. The rack 7 drives the gear 8 to rotate through meshing, and then can drive the two supporting cylinders 2 to rotate synchronously and in the same direction. The supporting cylinder 2 drives the rib plate to pass through the pressing cylinder 6 by means of friction. At this time, the pressing cylinder 6 and the supporting cylinder 2 can effectively roll and flatten the currently bent and deformed rib plate. When it is necessary to flatten rib plates of other thicknesses, control the rotation of the rotating shaft 4 in the above manner to drive other pressing cylinders 6 with different outer diameter specifications to be in the flattening station.

[0028] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
