In the production process of non-metallic material products, parts of various shapes must be cut from the whole sheet of material first. This process is called cutting or cutting or cutting. Blanking is a commonly used material processing method in industrial and agricultural production, with a variety of ways and methods, generally using tools to achieve under a certain external force, such as: cutting, cutting, cutting, cutting, etc. According to the cutting process characteristics and cutting machine principle, can be divided into blanking and cutting.
(1) Cutting machine (blanking equipment)
Blanking is the effect of external force, such as tool, punch and other impact to the leather material inside the cut off. Blanking has the characteristics of short acting time, high production efficiency, but large shear force, suitable for mass production and so on.
From the relative position and relative motion of the cutting tool and the leather, the blanking process can be carried out in the following ways:
Method one: place the leather, non-woven cloth, sponge and other non-metallic materials, and execute the cutting and cutting motion of the punching mechanism and the cutting tool. Artificial material material displacement, for the next blanking.
Method two: place the non-metallic material, the cutter moves in a straight line, and the leather non-metallic material moves in a plane automatically.
Method three: The material does not move, the cutter does the cutting movement and the displacement movement.
Conclusion: the cutting machine is mainly suitable for cutting small area of the parts, the number of pieces more.
(2) Cutting and cutting is the use of scissors tools, segmenting continuous material cutting and cutting has the characteristics of labor saving, high material separation utilization rate, but the cutting time is long, low production efficiency, labor and time consuming, generally suitable for single piece, or small batch production. When cutting, the cutter cuts and moves, and cutting is just like cutting cloth with scissors.
When selecting the cutting method, the characteristics of cutting materials, production capacity and production efficiency should be considered comprehensively to select the equipment relative to the cutting material.
