Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold rolling mill technology, specifically to a high-precision cold rolling mill structure that prevents deviation. Background Technology
[0002] Cold rolling: Using hot-rolled steel coils as raw material, after pickling to remove oxide scale, it undergoes continuous cold rolling. The finished product is a hard-rolled coil. Due to work hardening caused by continuous cold deformation, the strength and hardness of the hard-rolled coil increase, while its toughness and plasticity decrease, thus deteriorating its stamping performance and limiting its use to parts with simple deformation. Hard-rolled coils can be used as raw material in hot-dip galvanizing plants because hot-dip galvanizing units are equipped with annealing lines. The weight of a hard-rolled coil is generally between 6 and 13.5 tons. The steel coil is continuously rolled from hot-rolled pickled coils at room temperature. To ensure the accuracy of cold rolling, a high-precision cold rolling mill structure with anti-deviation is required.
[0003] The existing patent, CN219004114U, entitled "A Plate Guiding and Limiting Structure for a Cold Rolling Mill," discloses a plate guiding and limiting structure for a cold rolling mill. It includes a work box, a rotating device, and first processing columns. Multiple first processing columns are arranged on both sides inside the work box. Engaging devices are installed on both sides of each first processing column, and a rotating device is installed on the outer side of each engaging device. A limiting structure is provided between two first processing columns. The engaging device includes a first telescopic cylinder, a telescopic column, and a second slot. Locking blocks are provided on both sides of each first processing column. A telescopic column is located on the outer side of the left locking block. The telescopic column has a first slot inside and is installed inside the first telescopic cylinder. The left side of the first telescopic cylinder is connected to the rotating device, and the right side of the locking block has a second slot connected to the rotating device. This utility model facilitates the production of plates of different shapes according to customer needs, improves the applicability of the device, and also facilitates adjustment of the width of the finished plate.
[0004] The above-mentioned device activates the telescopic rod inside the second telescopic cylinder to slide according to the required width of the material. The telescopic rod drives the limiting plate to slide, which facilitates the adjustment of the width of the finished plate. However, the feeding posture of the material plate needs to be adjusted during cold rolling to prevent cold rolling deviation, which cannot well meet people's usage needs. In view of the above situation, technical innovation is carried out on the basis of the existing high-precision cold rolling mill structure. Utility Model Content

[0011] Furthermore, a threaded post is installed on one side of the upper cold rolling roll, and the threaded post is threadedly connected to the upper cold rolling roll. Rotating the threaded post drives the upper cold rolling roll to move up and down.
[0012] Furthermore, a second bevel gear set is installed at the lower end of the threaded column, and the second bevel gear set is welded to the threaded column.
[0013] Furthermore, a linkage rod is installed on one side of the bevel gear set two, and the linkage rod two is welded to the bevel gear set two.

[0015] 1. In this utility model, the material plate is placed on the base, the motor drives the linkage rod to rotate, and the two bevel gear sets on the linkage rod drive the lead screw to rotate respectively.

The side pulley and the pressure pulley abut against the material plate, which facilitates the movement of the material plate and fixes the feeding trajectory of the material plate, preventing the material plate trajectory from deviating during feeding.
[0016] 2. In this utility model, the material plate is cold-rolled between the upper and lower cold rolling rolls. The rotating threaded column drives the upper cold rolling roll to move up and down.

[0021] like Figure 1-3As shown, a high-precision cold rolling mill structure with anti-deviation capability includes a base 1 and a side plate 2. A motor 10 is installed on the right side of the interior of the base 1, and a linkage rod 8 is installed on one side of the motor 10. The side plate 2 is slidably connected to the top of the base 1, and a side pulley 3 is rotatably connected inside the side plate 2. A pressure plate 5 is installed on the inner side of the side plate 2, and the pressure plate 5 is slidably connected to the side plate 2. An adjusting stud 4 is threaded inside the pressure plate 5, and a pressure pulley 6 is provided on one side of the adjusting stud 4. A tapered rod is installed on the outer side of the linkage rod 8. Gear set 9, and a lead screw 7 is provided on one side of bevel gear set 9. When the material plate is placed on the base 1, the motor 10 drives the linkage rod 8 to rotate. The two bevel gear sets 9 on the linkage rod 8 drive the lead screw 7 to rotate respectively. The threads of the two parts on the lead screw 7 are opposite, which drives the side plate 2 to move closer together to clamp the material plate. Rotating the adjusting stud 4 drives the pressure plate 5 to press down and press the material plate. The side pulley 3 and the pressure pulley 6 abut against the material plate, which facilitates the movement of the material plate and fixes the feeding trajectory of the material plate to prevent the material plate trajectory from deviating during feeding.
[0022] like Figure 1 As shown, a cold rolling assembly 11 is installed on the left side of the base 1, and the cold rolling assembly 11 is rotatably connected to the base 1. The cold rolling assembly 11 includes an upper cold rolling roll 1101 and a lower cold rolling roll 1102, and the lower cold rolling roll 1102 is installed below the upper cold rolling roll 1101. A threaded post 12 is installed on one side of the upper cold rolling roll 1101, and the threaded post 12 is threadedly connected to the upper cold rolling roll 1101. A bevel gear set 2 13 is installed at the lower end of the threaded post 12, and the bevel gear set 2 13 is welded to the threaded post 12. A linkage rod 2 1 is installed on one side of the bevel gear set 2 13. 4. The linkage rod 14 and the bevel gear set 13 are welded together. The material plate is cold rolled between the upper cold rolling roll 1101 and the lower cold rolling roll 1102. The rotating threaded column 12 drives the upper cold rolling roll 1101 to move up and down. At the same time as the threaded column 12 rotates, it drives the linkage rod 14 to rotate through the bevel gear set 13. The linkage rod 14 drives the threaded column 12 on the other side to rotate, so that the two threaded columns 12 rotate synchronously and drive the upper cold rolling roll 1101 to move up and down smoothly. This changes the distance between the upper cold rolling roll 1101 and the lower cold rolling roll 1102, making it easier to control the degree of cold rolling.
[0023] Working principle: When using this anti-deviation high-precision cold rolling mill structure, firstly, the material plate is placed on the base 1. The motor 10 drives the linkage rod 8 to rotate. The two bevel gear sets 9 on the linkage rod 8 drive the lead screw 7 to rotate respectively. The threads of the two parts on the lead screw 7 are opposite, thereby driving the side plates 2 to move closer together and clamp the material plate. Rotating the adjusting stud 4 drives the pressure plate 5 to press down and hold the material plate. The side pulley 3 and the pressure pulley 6 abut against the material plate, facilitating the movement of the material plate and fixing the feeding trajectory of the material plate, preventing the material plate from derailing during feeding. The material plate is cold-rolled between the upper cold rolling roll 1101 and the lower cold rolling roll 1102. The rotating threaded column 12 drives the upper cold rolling roll 1101 to move up and down. At the same time, the threaded column 12 rotates through the bevel gear set 2 13 to drive the linkage rod 2 14 to rotate. The linkage rod 2 14 drives the threaded column 12 on the other side to rotate, so that the two threaded columns 12 rotate synchronously and drive the upper cold rolling roll 1101 to move up and down smoothly. This changes the distance between the upper cold rolling roll 1101 and the lower cold rolling roll 1102, making it easier to control the degree of cold rolling.
