Description

Technical Field

[0001] The utility model relates to a side looper device for a steel rolling bar production line, belonging to the technical field of steel rolling bar production. Background Art

[0002] At present, the entire bar production line in the bar operation area generally includes a rough rolling unit, an intermediate rolling unit, and a finishing rolling unit. The structure and layout of the rolling mill are short-stress horizontal and vertical alternating types. The rough rolling unit and the intermediate rolling unit adopt micro-tension rolling, and the looper control is adopted after the rolled piece passes the last rolling mill of the intermediate rolling unit to achieve tension-free rolling. The height of the looper depends on the difference in the "second flow" of the front and rear racks. If the "second flow" of the front and rear racks is equal, the looper height value between adjacent racks is "0". In actual rolling production, the cross-sectional size of the billet after the intermediate rolling is relatively large. In actual production, there are many factors that affect the flow rate per second, such as uneven temperature, thermal expansion and wear of the rolls, pressure adjustment, poor stability of the rolling mill, etc. Cross factors lead to mismatched linear speeds between racks. The unequal flow rate per second requires that adjacent rolling mills must have a faster control system to compensate for the imbalance of the flow rate per second by increasing or decreasing speed. Due to the lag and limitation of the control system, the billet exerts a "pulling force" on the body of the looper mechanism. This phenomenon is particularly prominent on the side looper between the intermediate rolling and the finishing rolling, which is the reason for the frequent maintenance and replacement of the side sleeve push roller and assembly. It takes more than 30 minutes to normally overhaul and replace the looper mechanism, and at least 10 minutes for actual online repair, which seriously affects production efficiency.

The screw rod has two threaded sections (not shown) arranged at intervals, and the two threaded sections rotate in opposite directions. Screw sleeves 14 are respectively screwed on the two threaded sections, and the screw sleeves 14 are respectively arranged on the outer sides of the clamping plates 10 on the corresponding sides. A compression spring 13 is also arranged between the two clamping plates 10, and the compression spring 13 is sleeved on the screw rod 11. Turntables 12 are respectively arranged at both ends of the screw rod 11. Rotating the turntables 12 drives the screw rod 11 to rotate, so that the two screw sleeves 14 are relatively close to or relatively far away from each other along the screw rod 11, thereby driving the two clamping plates 10 to be relatively close to each other and clamped on the rolling mill, and the compression spring is compressed; or relatively far away and the rolling mill is released, and the compression spring is reset, which is convenient for fixing to the rolling mill or disassembling from the rolling mill.
