Rolling mill guide and guard device capable of changing shape of guide and guard opening according to steel

Abstract

The invention provides a rolling mill guide and guard device capable of changing the shape of a guide and guard opening according to steel, and relates to the technical field of rolling mills. The device comprises a lower guide box, screw rods penetrating through and extending to the top of the lower guide box are movably connected to the two sides of the lower guide box, and the tops of the screwrods are in threaded connection with an upper guide box matched with the lower guide box body. The middle of the lower guide box and the middle of the upper guide box are movably connected with limiting toothed rods. According to the rolling mill guide and guard device capable of changing the shape of the guide and guard opening according to steel, due to the cooperation of a hand wheel and the screw rods, when the distance between the upper guide box and the lower guide box is adjusted, the hand wheel is rotated, the hand wheel hand wheel drives an adjusting gear to rotate through a connecting rod, the adjusting gear drives a transmission gear rod to rotate, the transmission gear rod drives a threaded gear to rotate, and the threaded gear drives the upper guide box to move up and down along the screw rods, so that the effect of convenient adjustment is achieved. Bolts do not need to be adjusted one by one like in a traditional mode. Unified adjustment is achieved, and the clamping degree of the upper guide box and the lower guide box is ensured.

Description

Technical field [0001] The invention relates to the technical field of rolling mills, in particular to a guiding and guarding device of a rolling mill that can change the shape of a guide opening according to steel. Background technique [0002] The rolling mill is a kind of equipment used to process steel. It guides the heated steel into the rolling mill for rolling. At present, most of the guiding and guarding devices of the rolling mill are U-shaped grooves. When the steel enters the rolling mill, it slides Into the rolling mill, but the current rolling mill still has the following problems during use: [0003] The current guide and guard device has a fixed guide and guard port shape, and the shape of the guide guard cannot be changed. As a result, steel can only enter the guide and guard device according to a fixed feeding method, and the steel may need to be processed at a specific angle during processing. The shapes are also different. The current guide openings cannot meet ...

AI Technical Summary

Problems solved by technology

[0003] The shape of the guide port of the current guide device is fixed, and the shape of the guide port cannot be changed. As a result, the steel can only enter the guide device according to the fixed feeding method, and the steel may need to be processed at a specific angle during processing, and various types of steel The shape is also different. The current guide port cannot meet the above requirements, which eventually leads to the waste of steel processing, resulting in waste of steel, resulting in the need for reprocessing of steel, waste of resources, and insufficient energy saving. When the distance between the body and the lower guide box body needs to be adjusted one by one, the steps are cumbersome and inconvenient to adjust
