Problems solved by technology

[0008] However, manual deburring takes a lot of time and is difficult to apply to mass production
In addition, deburring often creates scratches and scratches cause cracks to form, therefore, there is a potential hazard that may damage the product

Abstract

The present disclosure provides a shearing method for improving the quality of a steel plate shearing edge, and a shearing apparatus to improve the quality of the steel plate shearing edge. The apparatus includes: a die; a stripper for fixing a steel plate positioned on the top of the die; a trim punch for shearing the steel plate fixed between the die and the stripper, and a finishing die for reducing an area ratio of a fracture surface of a shearing edge formed by shearing the steel plate and removing a burr. By using the apparatus, components can be prevented from being damaged and a life-span can be increased through removing a burr generated at the shearing edge of the steel plate and reducing a fracture surface ratio.

Description

[0001] References to related applications [0002] This application claims the benefit of Korean Patent Application No. 10-2015-0009865 filed on January 21, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to a shearing device and method for improving the quality of a steel plate's shearing edge. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] In general, most machines and mechanical devices are composed of a combination of various parts, and the metal or non-metal parts used here are respectively manufactured by a predetermined processing method suitable therefor. [0006] Here, in metal parts, burrs cannot be generated at shearing edges by non-cutting methods such as casting or forging, but burrs can be generated by trimming or piercing methods. In devices that do no...
