Circle shearing blades, also known as rotary shear blades or circular shear knives, are circular cutting tools used in circle shearing machines. These machines are designed for cutting sheet metal, coils, and other materials into circular blanks, discs, or rings. Circle shearing blades typically work in pairs, with an upper and a lower circular blade rotating against each other to create a precise and clean cut. The term “circle shearing blades” clearly indicates their circular shape and their primary application in circle shearing processes.<\/p>\r\n
Circular shearing blades are essential in various metalworking industries for producing circular shapes from sheet metal and coils. Their key applications include:<\/p>\r\n
The materials used for circle shearing blades must possess high hardness, wear resistance, and toughness to withstand the forces involved in cutting metal and to maintain a sharp cutting edge for accurate and clean cuts. Common materials include:<\/p>\r\n
Circle shearing blades are precision ground to achieve the required sharpness and dimensional accuracy. The bevel angle of the cutting edge is critical and is determined by the type and thickness of the material being cut. Proper heat treatment to achieve the optimal hardness is essential for maximizing blade performance and lifespan.<\/p>\r\n
Circle shearing blades<\/strong> are primarily circular but can have variations in their edge profiles and overall design to optimize cutting performance:<\/p>\r\n The working principle of circle shearing blades involves two circular blades mounted on rotating shafts, with a precise gap between them. The sheet metal or coil is fed between these rotating blades. As the blades rotate, the material is sheared progressively along a circular path. The speed of rotation, the feed rate of the material, the sharpness and profile of the blade edges, and the gap between the blades all contribute to the quality and accuracy of the circular cut. Proper alignment and maintenance of the circle shearing blades are crucial for achieving clean, burr-free edges and maximizing blade life.<\/p>\r\n \u0625\u0630\u0627 \u0644\u0645 \u062a\u062c\u062f \u0627\u0644\u0634\u0641\u0631\u0629 \u0627\u0644\u062a\u064a \u062a\u0628\u062d\u062b \u0639\u0646\u0647\u0627\u060c \u064a\u0645\u0643\u0646\u0646\u0627 \u0623\u064a\u0636\u064b\u0627 \u062a\u062e\u0635\u064a\u0635\u0647\u0627. \u0627\u0637\u0644\u0639 \u0639\u0644\u0649 \u0642\u0633\u0645 "\u0634\u0641\u0631\u0627\u062a \u0645\u062e\u0635\u0635\u0629<\/strong><\/em><\/a>"<\/span> \u0644\u0645\u0639\u0631\u0641\u0629 \u0627\u0644\u0645\u0632\u064a\u062f\u00a0\u0646\u0631\u062d\u0628 \u0628\u0627\u0633\u062a\u0641\u0633\u0627\u0631\u0627\u062a\u0643\u0645<\/a><\/strong><\/em><\/span><\/p>\r\n \u0627\u0633\u062a\u0645\u062a\u0639 \u0628\u0631\u0627\u062d\u0629 \u0627\u0644\u0627\u0633\u062a\u064a\u0631\u0627\u062f \u0627\u0644\u0633\u0644\u0633. \u0645\u0646 \u0627\u0644\u0646\u0642\u0644 \u0625\u0644\u0649 \u0627\u0644\u062a\u062e\u0644\u064a\u0635 \u0627\u0644\u062c\u0645\u0631\u0643\u064a\u060c \u0646\u062d\u0646 \u0646\u062a\u0639\u0627\u0645\u0644 \u0645\u0639 \u0627\u0644\u0639\u0645\u0644\u064a\u0629 \u0628\u0623\u0643\u0645\u0644\u0647\u0627. \u0643\u0644 \u0645\u0627 \u0639\u0644\u064a\u0643 \u0641\u0639\u0644\u0647 \u0647\u0648 \u062f\u0641\u0639 \u0636\u0631\u064a\u0628\u0629 \u0627\u0644\u0642\u064a\u0645\u0629 \u0627\u0644\u0645\u0636\u0627\u0641\u0629 \u0648\u0627\u0646\u062a\u0638\u0627\u0631 \u0648\u0635\u0648\u0644 \u0628\u0636\u0627\u0626\u0639\u0643.<\/p>\r\n \u0644\u0642\u062f \u0631\u0623\u064a\u0646\u0627 \u0634\u0641\u0631\u0627\u062a\u0646\u0627 \u062a\u064f\u0633\u062a\u062e\u062f\u0645 \u0641\u064a \u0639\u062f\u062f \u0644\u0627 \u064a\u062d\u0635\u0649 \u0645\u0646 \u0627\u0644\u062a\u0637\u0628\u064a\u0642\u0627\u062a \u0648\u0647\u064a \u062c\u0627\u0647\u0632\u0629 \u0644\u0644\u062a\u0639\u0627\u0645\u0644 \u0645\u0639 \u0623\u064a \u0645\u0634\u0631\u0648\u0639 \u062a\u0637\u0631\u062d\u0647 \u0639\u0644\u064a\u0646\u0627 -
