Cold stamping die process is a kind of metal processing method, which is mainly for metal materials, through the punching press and other pressure equipment to force the material deformation or separation, in order to meet the actual requirements of the product parts, referred to as: stamping parts.

The stamping process of the mold is as follows:

1. Blanking is a general term for a stamping process in which materials are separated. It includes: blanking, punching, punching, punching, cutting, cutting, cutting, cutting tongue, cutting and so on

2. The lower shape is mainly a stamping process of cutting off a ring of excess material outside the material to meet the size requirements

3, cutting tongue to a certain part of the material to cut a slit, but not all cut, usually for the rectangle only cut three sides and keep one side is not moving, the main role is to set the step distance.

4, flaring this process is not common, most of the tubular parts need to expand the end or a place outward to the trumpet shaped situation

5, the contraction and the expansion is just the opposite, the tubular parts need to be the end or a place to shrink inward a stamping process

6, punching in order to get the hollow part of the parts, the middle of the complete material through the punch and the cutting edge to separate the material to get the corresponding hole size

7, fine punching when the stamping part needs the section quality of the full bright zone, it can be called “fine punching” (Note: ordinary punching cutting surface is divided into four parts: collapse Angle zone, bright zone, fault zone, burr area)

8, the difference between full light blanking and fine blanking is that full light blanking must be obtained in one step blanking and fine blanking is not

9, deep hole punching when the product aperture is less than the thickness of the material can be understood as deep hole punching, the punching difficulty is easy to break

10, hit the convex hull in the flat material to hit a bump and play the corresponding use requirements of the process

11, forming many friends understand forming as bending, this is not rigorous. Because bending is a type of molding, molding refers to the general name of all fluid material processes

12. Bending is a conventional process in which the flat material is plastic deformed through the convex and concave die inserts to obtain the corresponding Angle and shape

13, this is generally used in the sharp Angle bending molding insert, mainly through the bending position of the material out of the convex pit to reduce the material rebound, to ensure the stability of the Angle of a structure

14, embossing on the surface of the material through the punch to press out a special pattern of a process, common: embossing, pitting and so on

15, roll round forming process, is a process by curling the product shape into a circle

16. The process of turning the inner hole of the stamping part out to get a certain height of the side

17. Leveling is mainly for the situation that the flatness of the product is higher. When the flatness of the stamping parts is out of whack due to the stress, it is necessary to use the leveling process for leveling

18, shaping when the product molding is completed, the Angle, shape is not the theoretical size, we need to consider adding a process to fine-tune to ensure the stability of the Angle, this process is called “shaping”

19, deep drawing usually refers to the plate material through the method to get the hollow parts of the process known as the drawing process, mainly through the convex and concave die to complete

20. Continuous deep drawing usually refers to a drawing process formed by several times drawing the material in the same position through a pair or several molds in a material belt

21, thin drawing continuous stretching, deep stretching belong to the thin stretching series, refers to the tensile parts after the wall thickness will be less than the thickness of the material itself

22, drawing its principle is similar to convex hull, the material is convex. However, drawing usually refers to automotive parts, which belong to a more complex forming series, and its drawing structure is relatively complex

23, engineering mold a set of mold a stamping process can only complete a stamping process of the mold collectively

24, a set of composite mold a stamping process can be completed two or more than two different stamping processes of the mold collectively

25. A set of progressive die is fed by the material belt, and more than two kinds of working procedures are arranged in sequence. With the stamping process, the general name of the mold type of the final qualified product is given in turn
