Description

Technical Field

[0001] The invention relates to the technical field of mechanical cutting, in particular to an automatic cutting mechanism. Background Art

[0002] Mechanical cutting is a process that uses mechanical equipment to cut metal or other materials. It mainly includes shearing, sawing and grinding, and is suitable for cutting various profiles, plates and pipes. The essence of mechanical cutting is that the processed metal is squeezed by scissors to cause shear deformation and cracking separation. Common mechanical cutting equipment includes shearing machines, sawing machines and grinders. Shearing machines are mainly used for cutting steel plates. The maximum shearing thickness is generally around 20mm, and it is suitable for various straight line cutting.

[0003] Mechanical cutting is a common rough processing method in heavy industry and belongs to cold cutting. Although the proportion of mechanical cutting has decreased with the development of technologies such as flame cutting and arc cutting, it is still an indispensable cutting method in process equipment manufacturing. The advantages of mechanical cutting include simple operation, low labor cost, high cutting quality and efficiency. The disadvantage is that the cutting thickness is limited and it is only suitable for various straight line cutting. Compared with flame cutting, mechanical cutting is suitable for smaller size materials.
