An experimental teaching rolling mill synchronous-asynchronous pressing dual-purpose device

Abstract

The invention discloses a synchronous-asynchronous pressing dual-purpose device of an experiment teaching rolling mill. The dual-purpose device comprises a machine frame, an upper roller, a lower roller, two screws, a driving gear, two driven gears and a supporting table. The upper roller is arranged at the upper portion of the machine frame through a slider. The lower roller is arranged at the lower portion of the machine frame. The slider is slidingly connected with the machine frame. The lower ends of the two screws are rotationally connected with the sliders respectively. The upper ends ofthe two screws are sequentially connected with the machine frame, the supporting table and the driven gears. The screws are in threaded connection with the machine frame. The two ends of the supporting table are rotationally connected with the screws. The driven gears are fixedly connected with the screws. The driving gear is detachably connected with the supporting table. The driving gear is meshed with the two driven gears. By designing the driving gear and the supporting table into a detachable structure, the switching of the rolling mill between a synchronous pressing mode and an asynchronous pressing mode is realized, and the experiment teaching requirement is met.

Description

technical field [0001] The invention relates to the technical field of rolling mills, in particular to an experimental teaching rolling mill synchronous-asynchronous pressing dual-purpose device. Background technique [0002] The manual pressing device of the rolling mill generally adjusts the size of the roll gap by adjusting the rotating discs on both sides of the roll to obtain plates of different thicknesses. There are two types of traditional laboratory rolling mills. The two rotating discs of one kind of rolling mill are independent (such as figure 1 ), no matter how it is adjusted, there may be inconsistent rotations on both sides of the rolls, resulting in inconsistent roll gaps on both sides, that is, this kind of rolling mill can achieve asynchronous reduction, but it is difficult to achieve synchronous reduction; Synchronous pressing can be realized, that is, the situation where the roll gaps on both sides are consistent, but asynchronous pressing cannot be reali...

Problems solved by technology

However, the traditional rolling mill can only realize synchronous pressing or asynchronous pressing, and cannot realize the dual-purpose function of synchronous and asynchronous, and cannot meet the needs of experimental teaching.
