The working principle of a rolling shearing device is as follows: the motor drives 1 to drive the driving sprocket 10, the driving sprocket 10 drives the driven sprocket 8 to rotate through the chain 9, the driven sprocket 8 drives the lower hob assembly 5 to run, and at the same time The driving gear 7 rotates with the lower hob assembly 5, and drives the driven gear 6 to run, and the driven gear 6 drives the upper hob assembly 4 to run. Metal sheet material can be fed from one side between the upper hob assembly 4 and the lower hob assembly 5, and the metal sheet conveyed from the other side under the engagement of the upper hob assembly 4 and the lower hob assembly 5 The material is finished shearing.

The utility model has the following beneficial effects:

1. A pair of hob assemblies are installed up and down. When working, the upper and lower hob assemblies operate continuously, which can improve the production efficiency when cutting thin plates;

2. The upper hob assembly and the lower hob assembly are equipped with rubber sleeves between the hobs, which can greatly improve the warping and curling of the thin sheet during the shearing process. The edge of the sheet to be cut is smooth and the cutting quality high;

3. The structure is simple, compact and easy to maintain.
