Common Terminology For Mold Design

- Aug 14, 2018-

16. Pull marks: Pull marks are the rubbing marks of the surface of the stamping material and the working surface of the mold during the forming process.


17. Drawing ratio: The drawing ratio is the reciprocal of the drawing coefficient.


18. 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 of the previous process. For the first draw, the draw ratio is the ratio of the diameter of the draw to the diameter of the draw.


19. Lug: The lug is an ear-shaped protrusion that draws the edge of the upper edge of the piece.


20. Feeding: Feeding is the feeding of raw materials into the mold for stamping.


21. Feeding device: The feeding device is the device that feeds the raw material into the mold. The common feeding device has roller-type, clamp-holding type, hook-type and so on.


22. Hopper: The hopper is a bucket-shaped container with a mechanism for automatically orienting the shaped punch.


23. Unfolded view: The expanded view is a planar process piece graphic corresponding to the shaped punch.


24. Unfolded Size: The unfolded size is the size of the planar process piece corresponding to the size of the formed punch.


25. Arching: Arching is the name of the phenomenon that the surface of the punching piece is arched.


26. Wrinkling: Wrinkling is the name of the phenomenon that the flange of the deep drawing member has wavy wrinkles.


27. Chute: The chute is a trough-shaped passage that allows the punch to enter or exit the mold sequentially.


28. Hook Feeding Device: The hook feeding device is a device that uses a reciprocating hook to extend into the hole to drive the raw material into the die.


29. The piece: the piece is a stack of punching parts (mostly punching parts).


30. The device device: the device device is a device for stacking the punches.


31. Layout: Layout is the die design process for completing the layout. The layout map is sometimes referred to as a layout. The layout drawing is a layout diagram describing the process in which the punching piece is gradually formed on the strip (belt, roll), and the position of the final possession and the relationship between the adjacent punches.


32. Stick mold: The stick mold is the name of the phenomenon that the working surface of the die is bonded to the punch material.


33. Crushing: The chipping is the name of the phenomenon that the punch or die edge is peeled off.
