Description

Technical Field

[0001] This invention relates to the field of phosphorus breaking and straightening machine technology, and specifically to a multi-roll box quick roll changing device for a phosphorus breaking and straightening machine. Background Technology

[0002] The descaling and straightening machine is a key metallurgical equipment that integrates mechanical descaling and strip shape straightening functions. It is widely used in the front end of cold rolling pickling production lines. It provides stable tension through tension roller groups, allowing the strip steel to pass through multiple sets of bending rollers and straightening rollers in multiple roller boxes under tension. The bending unit uses large bending deformation to cause the dense iron oxide scale on the surface of the strip steel to crack and fall off, achieving mechanical descaling. This creates favorable conditions for the subsequent pickling process, greatly improves pickling efficiency and reduces acid consumption. It is an important piece of equipment to ensure the surface quality of the strip steel and the accuracy of subsequent processing. In traditional phosphorus breaking and straightening machines, when the bending and straightening rollers are not performing well, they are usually lifted off the machine body along with the roller box by hoisting. However, this method requires a lot of space and multiple people to work together, making the replacement of the roller box inefficient.

[0026] The upright frame 25 is fixedly connected to one end of the top of the placement plate 15. Both ends of the upright frame 25 are rotatably connected to the linkage shaft 26. The linkage shaft 26 is fixedly connected to the transmission spur gear 27 and the eccentric plate 28. The transmission spur gear 27 is also meshed with the corresponding guide spur gear 24.

Please refer to Figure 6 In this embodiment, a stabilizing rod is vertically slidably connected to the top of the support frame 25, and the bottom end of the stabilizing rod is fixedly connected to the pusher seat 31.

Please refer to Figure 7 In this embodiment, the top of the anti-slip seat plate 37 is provided with an insertion hole, and a rod is fixedly connected to the bottom of one side of the guide frame 35, and the rod is also inserted into the inside of the insertion hole. More specifically, through the structural cooperation of the socket and the rod, before assembling the anti-slip seat plate 37, the socket is first aligned with the rod, and the anti-slip seat plate 37 is pushed. As the anti-slip seat plate 37 is adjusted, the rod will be inserted into the socket to provide guidance for the assembly of the anti-slip seat plate 37 and ensure that the anti-slip seat plate 37 can reach the designated assembly position. Furthermore, the bottom of the anti-slip seat plate 37 is provided with anti-slip texture. The anti-slip texture can improve the friction between the anti-slip seat plate 37 and the ground, prevent the moving wheels 2 from moving, and ensure the stability of the pallet 1 when it is parked. Please refer to Figure 8 In this embodiment, the middle part of the extension ear 43 and the end of the displacement plate 40 away from the anti-rotation ring 41 are both fixedly connected to the positioning shaft, and the two ends of the linkage rod 44 are respectively rotatably connected to the corresponding positioning shaft. More specifically, both ends of the linkage rod 44 have mounting holes, and ball bearings are provided at the connection between the mounting holes and the positioning shaft. The mounting holes provide space for the ends of the linkage rod 44 to accommodate the positioning shaft, and the ball bearings allow the linkage rod 44 to be smoothly adjusted between the extension ear 43 and the anti-rotation ring 41 according to the vertical displacement of the guide frame 35.

[0027] This embodiment provides a multi-roller box quick roll changing device for a phosphorus breaking and straightening machine. First, the pallet 1 is pushed, and with the assistance of the moving wheel 2, the pallet 1 can move at the phosphorus breaking and straightening machine. When the pallet 1 moves to the roll box of the phosphorus breaking and straightening machine, the hydraulic cylinder 13 is activated, and the adjusting arm 10 is pushed through the guide ring 14 to drive the guide shaft 3 connected to it to rotate. In conjunction with the connection between the guide shaft 3 and the guide arm A, as the guide arm A follows the guide shaft 3 to rotate, the support platform 4 can be pushed with the help of the guide arm B8, so that the support platform 4 can make adaptive height adjustments until the height of the positioning plate 15 is adapted to the roll box. Then, the hydraulic rod B34 is activated to push the guide frame 35 vertically until the anti-slip seat plate 37 contacts the ground, thereby increasing the resistance of the pallet 1 during movement and preventing the pallet 1 from slipping. Since the linkage rod 44 is connected between the extension ear 43 and the linkage rod 44, as the extension ear 43 moves with the guide frame 35, it can push the displacement plate 40 with the help of the linkage rod 44, causing the displacement plate 40 to move under the support of the displacement rod 39. When the anti-slip seat plate 37 contacts the ground, the anti-rotation ring 41 will fit tightly with one of the anti-slip plates 42, thereby increasing the resistance when the guide shaft rod 3 rotates and preventing the guide shaft rod 3 from rotating uncontrollably. Then, the drive motor 19 is restarted to drive the drive screw 18 to rotate. Combined with the connection between the drive screw 18 and the traction ear 20, the traction ear 20 can drive the settling plate 15 to adjust along the drive screw 18 and move it closer to the roller box. The roller box is then mechanically placed on top of the settling plate 15. Simultaneously, the hydraulic rod A30 is activated to push the guide seat 31 to vertical displacement. Since the pressure rod 32 is connected inside the guide groove 29, during the adjustment process of the pressure rod 32 following the guide seat 31, the adaptability of the pressure rod 32 within the guide groove 29 allows for greater flexibility. The roller box is positioned by moving the guide spur gear 24 through the transmission spur gear 27 until the positioning plate 23 contacts the roller box. Then, the transmission motor 19 is started to drive the transmission screw 18 to rotate, adjusting the positioning plate 15 above the support platform 4. Then, the hydraulic rod B34 is started to pull the guide frame 35 upward, so that the anti-slip seat plate 37 is away from the ground, and at the same time, the anti-rotation ring 41 contacts another anti-slip plate 42, which restricts the rotation of the guide shaft rod 3 again. Then, the roller box is moved to the designated area. Furthermore, if the anti-slip seat plate 37 does not perform well, rotate the threaded rod 46 to connect the threaded rod 46 with the positioning clamp 47, so that the positioning clamp 47 can be adjusted along the threaded rod 46. After the positioning clamp 47 moves away from the anti-slip seat plate 37, the anti-slip seat plate 37 can be unlocked, and then the anti-slip seat plate 37 can be removed from the guide frame 35 and replaced.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
