Technical Term For Mold

Coils are raw materials in rolls that can be used for multiple punches. Sheets Sheets are sheet-like raw materials that can be used for multiple stampings. Strips Strips are strips of raw material that can be punched multiple times. Pull marks Pull marks are the friction marks between the surface of the material and the working surface of the mold during the forming process of the stamping. Drawing ratio The drawing ratio is the inverse of the drawing coefficient. See "Drawing Factor". Drawing coefficient The drawing coefficient is the ratio of the diameter of the cylindrical drawing part in this process to the diameter of the drawing part in the previous process. For the first drawing, the drawing factor is the ratio of the drawn part diameter to the expanded diameter. The lugs are the ear-shaped protrusions on the upper mouth edge of the drawing piece. Feeding Feeding is the feeding of raw materials into the die for stamping. Feeding device The feeding device is the device that feeds the raw material into the mold. Common feeding devices include roller type, clamp type, hook type, etc. Please refer to the relevant terms. Hopper The hopper is a bucket-shaped container with a mechanism that automatically orients the formed punched out. Bending Radius The bending radius is the inner radius of the bending part of the punch. Expanded drawing The expanded drawing is a plane process part graphic corresponding to the forming punching part. Unfolded size The unfolded size is the size of the plane process piece corresponding to the size of the forming punch. Arching Arching is the name of the phenomenon in which the surface of the punching piece is arched and uneven. Wrinkling Wrinkling is the name of the phenomenon of wavy wrinkles in the flange of the drawn part. The trough The trough is the trough-shaped channel that makes the punching parts enter or leave the mold in sequence. Hook feeding device Hook feeding device is a device that uses the reciprocating hook to extend into the hole to drive the raw material into the die. Arrangement Arrangement is the stacking of punched parts (mostly punched parts). Piece handling device Piece handling system is a device that arranges and stacks punched pieces. Layout Layout is the die design process to complete the layout drawing. Sometimes the layout diagram is also referred to as layout. See "Layout Drawings". Layout drawing The layout drawing is a layout drawing describing the step-by-step formation process of the punching piece on the strip (belt, coil), the final occupied position and the relationship between the adjacent punching pieces. Die sticking Die sticking is the name of the phenomenon in which the working surface of the die is bonded to the punching material. Chipping Chipping is the name of the phenomenon of small pieces peeling off the edge of the punch or die. Minimum Bend Radius The minimum bend radius is the smallest bend radius that can be successfully bent. See "Bend Radius". Overlap The overlap is the minimum distance between the contours of adjacent punches in the layout drawing, or the minimum distance between the contour of the punch and the edge of the strip. The slump angle has two meanings, one refers to the phenomenon that the outer edge of the blanking part is near the concave die surface or the inner edge near the convex die surface is rounded, and the other refers to the height hg of the part of the blanking part that is slumped. . The slump surface The slump surface is the plane of the blanking part whose edge is slumped, that is, the opposite side of the burr surface. See "Burred Surfaces". Die tryout Die tryout refers to the experimental stamping after the die assembly is completed to assess the die performance and stamping quality. Roller feeder The roller feeder is a device that uses a pair of rollers to clamp the raw material and feed it into the die. The feeding of the material is accomplished by the periodic rotation of the rollers.
