2. Glossy: Glossy is a bright section of the blank that is cut out.

3. Rebound: There are two kinds of rebound, one is the difference between the size of the formed punch after being taken out of the mold and the corresponding size of the mold. For curved parts, it is generally expressed as an angular difference or a difference in radius. The other is the difference between the outer dimensions of the blanks that escape from the mold and the corresponding dimensions of the female molds or the difference between the inner dimensions and the corresponding dimensions of the punches.

4. Closing height closure: The closing height is the distance between the upper plane of the upper mold base or the plane of the lower mold base when the die is at the pole of the working position.

5. Stroke: The stroke is the distance between the ends of the upper and lower movements of the press slider. It is customary to refer to the up and down movement of the press slider as a stroke, such as “stroke down”, “stroke up”, “number of strokes per minute”, and so on.

6. Negative rebound: Negative rebound is the rebound of the radius of curvature after the shaped punch is removed from the mold, or the rebound of the material body after the punching member escapes from the mold.

7. Clamping feeding device: The clamping feeding device is a device for feeding raw materials into a die by clamping, relaxing and reciprocating motion of a mechanical, pneumatic or hydraulic machine.

8. Life: Lifetime refers to the number of times a die can be stamped once per grinding or the number of times a die can be stamped before it is scrapped. The former is called sharpening life and the latter is called total life.

9. Step: The step is the distance that each raw material that can be used for multiple stampings is fed at a time.

10. Gap: The gap is the difference between the corresponding dimensions of the punch and the die that cooperate with each other or the gap therebetween.

11. Single-sided gap: A single-sided gap is a gap from the center to one side or a gap on one side.

12. Blanks: Blanks are raw materials that are not stamped and are mostly used for one stamping. Blanks are sometimes referred to as blanks or wool.

13. Coil: Coil is a roll of raw material that can be used for multiple stamping.

14. Sheet: The sheet material is a sheet-like raw material that can be used for multiple stamping.

15. Strip: Strip is a strip of raw material that can be used for multiple stamping.

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.

34. Minimum Bend Radius: The minimum bend radius is the minimum bend radius that can be successfully bent.

35. Edge: The edge is the minimum distance between the contours of adjacent punches in the layout, or the minimum distance between the contour of the punch and the edge of the strip.

36. Angle of collapse: the angle of collapse has two meanings, one refers to the phenomenon that the outer edge of the blanking part is near to the concave die surface or the inner edge near the convex mold, and the other is the height of the section of the blanking section showing the angle of collapse.

37. Collapsed surface: The collapsed surface is the plane of the blanking part whose edge is at the angle of collapse, that is, the opposite side of the burr surface.

38. Test mode: Test mode refers to the test stamping performed after the mold assembly is completed to check the mold performance and the punch quality.

39. Roller Feeding Device: A roller feeding device is a device that clamps a raw material and feeds it into a die by using a pair of rollers. Feeding of the material is accomplished by periodic rotation of the rollers.

40. Upper pole: The upper pole is the upper end of the upper and lower movement of the press slider.

41. Lower pole: The lower pole is the lower end of the upper and lower movement of the press slider.

42. Burr: The burr is a sharp protrusion on the edge of the punched part of the punched piece.

43. Burr surface: The burr surface is the plane of the blanking piece with burrs on the edge. For blanking, the burr surface is the plane that contacts the punch; for punching, the burr surface is the plane that contacts the die.

44. Matte: The rough surface is the rough section of the blank that is torn.

45. Neutral layer: The neutral layer refers to a layer of material with zero strain in a curved punch.

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

47. Neutral layer coefficient: The neutral layer coefficient is a system used to determine the position of the neutral layer.

48. Double-sided gap: The double-sided gap is the sum of the gap from one side to the other side or the gap between the two sides.

49. Outlet device: The device for launching is a device for ejecting a punched workpiece from the mold.

50. Positive rebound: Positive rebound is a rebound in which the radius of curvature of the formed punch is increased after being taken out of the mold, or a rebound in which the material is solid after the punching member escapes from the mold.

51.Bending radius: The bending radius is the inner radius at which the punch bends.
