Technical Field
[0001] This utility model relates to the field of straightening machine technology, specifically a straightening machine that is easy to mechanically adjust. Background Technology
[0002] A straightening machine is a device used to straighten or correct metal materials. It is mainly used to address bending, twisting, or deformation problems in metal sheets, pipes, or profiles caused by stress or other factors during production. By applying appropriate force or pressure, the straightening machine restores the metal material to its original shape or dimensions, ensuring its quality and accuracy.
[0003] Utility model patent CN220111978U discloses a steel pipe straightening machine. The key technical points are: a base plate with several straightening rollers on its top surface; and a rust removal assembly on the top surface of the base plate for removing rust from the steel pipe. Using sandpaper, workers apply glue to the inner wall of an arc-shaped seat. A positioning plate, movable plate, baffle, limiting hole, second spring, locking post, base plate, and locking groove work together to move the locking post outside the locking groove on the base plate and restrict the movement of the movable plate. A first spring, base plate, support groove, mounting post, mounting block, and arc-shaped seat work together to move two arc-shaped seats forward and merge them. Workers use the sandpaper on the inner wall of the arc-shaped seat to polish the outer wall of the steel pipe, thereby removing rust and facilitating subsequent straightening of the steel pipe.
[0004] In existing technology, it is inconvenient to adjust the position of the straightening rollers during the use of straightening machines, and they cannot be well adapted to straightening steel pipes of different diameters. Therefore, improvements are needed. Utility Model Content

An adjustment mechanism 8 is provided on the connecting rods 7, and a moving mechanism 9 is provided on the fixed seats 6.
[0023] Please see Figure 1 , Figure 2 The adjusting mechanism 8 includes a connecting frame 81. The connecting frame 81 is fixedly sleeved on the outside of the connecting rod 7. The connecting frame 81 is connected to the inside of the connecting frame 81 by a threaded connection. The outside of the positive and negative screws 82 is rotatably sleeved with a support sleeve 83 through a bearing. The support sleeve 83 is fixedly connected to the worktable 1. Handles 84 are fixedly connected to both ends of the positive and negative screws 82. A slide rod 85 is fixedly connected to the inside of the connecting frame 81. The slide rod 85 is slidably connected to the worktable 1. A slide groove 86 is opened inside the worktable 1. The slide rod 85 is slidably connected inside the slide groove 86. By designing the slide groove 86, the slide rod 85 can slide inside the worktable 1. By designing the adjusting mechanism 8, the distance between the straightening rollers 5 on both sides can be easily adjusted.
[0024] Please see Figure 1 , Figure 3 , Figure 4 The moving mechanism 9 includes slots 91. A slot 91 is provided inside the connecting rod 7. A rod 92 is slidably connected inside the slot 91. Multiple slots 91 are evenly distributed inside the connecting rod 7. By designing multiple slots 91, the rod 92 can be inserted into slots 91 at different positions. The rod 92 is slidably connected to the fixed base 6. A pull block 93 is fixedly connected to the top of the rod 92, contacting the fixed base 6. A slider 94 is fixedly connected to one end of the rod 92, and the slider 94 is slidably connected to the fixed base 6. A spring 95 is provided inside the fixed base 6. One end of the spring 95 is fixedly connected to the slider 94, and the other end is fixedly connected to the fixed base 6. By designing the spring 95, its force can act on the slider 94.

[0025] The specific implementation process of this utility model is as follows: In use, the straightening rollers 5 are used to straighten the steel pipe by driving the steel pipe through the space between the two straightening rollers 5. When it is necessary to adjust the distance between the two straightening rollers 5, the handle 84 is turned directly. The handle 84 drives the positive and negative screws 82 to rotate. The positive and negative screws 82 rotate inside the support sleeve 83, causing the connecting frame 81 to make a threaded movement. The connecting frame 81 will drive the slide rod 85 to slide along the slide groove 86. At the same time, the connecting frame 81 will drive the connecting rod 7 to move. The connecting rod 7 will slide along the guide rod 10. The distance between the two straightening rollers 5 can then be flexibly adjusted to accommodate steel pipes of different diameters for straightening.
[0026] When it is necessary to adjust the relative position of the fixed seat 6 and the connecting rod 7, first pull the pull block 93 upward. The pull block 93 drives the insertion rod 92 to move upward, and the insertion rod 92 drives the slider 94 to move upward. The slider 94 will squeeze the spring 95. At the same time, the insertion rod 92 will drive the magnetic block 96 to move. When the magnetic block 96 moves upward and attracts the magnet 97, the insertion rod 92 can be pulled out from the slot 91. Then, the fixed seat 6 can be pushed to slide along the connecting rod 7. Then, the insertion rod 92 can be moved to reset it. At this time, the insertion rod 92 will be inserted into the slot 91 at another position. By the insertion and cooperation of the insertion rod 92 with the slots 91 at different positions, the interval of the straightening roller 5 on one side can be adjusted. Furthermore, any number of straightening rollers 5 can be combined and used as needed to improve the performance of the straightening machine.
