Description

Shearing device

Technical Field

The utility model relates to the technical field of automatic production equipment, in particular to a shearing device.

Background

In some product productions, it is necessary to shear the sheet material used for the product so that the longer complete sheet material is sheared into a cut of short sheet material of the desired size. For example, when capacitor production is performed, the positive and negative electrode foils and the electrolytic paper required for producing the core pack are cut into suitable sizes by using a cutting device, so that the materials are conveniently wound into the core pack by a winding device in the subsequent process.

However, most of the conventional shearing devices shear the sheet material by means of cross shearing, and because of the gap between the two scissors, the two scissors are not parallel when actually shearing, and a cross point exists when the two scissors cross, and the sheet material is sheared by means of the cross point. In the above circumstances, the scissors cannot well rely on the knife of the scissors to cut the sheet, because of the existence of the cross tangent point, the scissors are easy to wear in the use process, the service life of the scissors is shortened, and the sheet cutting effect is poor. For example, when the positive and negative electrode foils of a capacitor are sheared, the sheared foils are prone to have more burrs, so that the quality of the product is reduced, and phenomena such as implosion and unstable performance are prone to occur.
