Description

Technical Field

[0001] The utility model relates to the technical field of rolling mills, in particular to a modular rolling mill unit. Background Art

[0002] The modular rolling mill unit is a core equipment for high-speed rolling of wire rods developed based on the concept of modular independent transmission technology. The equipment adopts a multi-machine parallel configuration to simplify the mechanical structure. This design allows the same model of machine to be completely interchangeable, reducing the types and quantity of spare parts and effectively reducing production and operation costs. However, during the use of the existing modular rolling mill, the gap between the pressure rollers cannot be adjusted, and it can only adapt to the rolling of metal of fixed thickness, which is very inconvenient to use.

[0003] In order to address the above problems, the Chinese patent with the existing announcement number CN217315121U proposes a modular rolling mill and a rolling mill unit. The device adjusts the spacing between the first pressing roller and the second pressing roller through a hydraulic column, and adjusts the distance between the first limiting roller and the second limiting roller through the cooperation of a screw and a nut, thereby facilitating the limiting transmission of metal parts of different thicknesses.

[0004] However, although the above-mentioned modular rolling mill and rolling mill unit can adjust the distance between the two sets of pressure rollers through the hydraulic column, and then adjust the distance between the two sets of limit rollers through the nut and the screw, the modular rolling mill and rolling mill unit are extremely inconvenient to operate when adjusting the distance between the two limit rollers through the screw and the nut, resulting in low efficiency when adjusting the distance between adjacent limit rollers.

The driving disk 97 pulls the movable rod 93 to move through the connecting rod 96, so that the first movable plate 92 drives the limiting rod 91 to move and releases the limiting hole 1. 6, the position of the upper limit roller 7 can be adjusted by pulling the handle 8. After the adjustment, the buckle plate 17 is released. At this time, the rack 983 and the movable plate are reset under the action of the first spring 94 and the second spring 4, so that the limit rod 91 limits the limit hole 16 again, that is, the distance between the upper limit roller 7 and the lower limit roller 6 is changed.
