Cold stamping die technology is a kind of metal processing method, which is mainly aimed at metal materials. It forces the materials to deform or separate through pressure equipment such as punch, so as to get the product parts that meet the actual requirements.
Die stamping process has a lot of circumstances, many friends do not understand this, small make up here to summarize the most common stamping process. As follows:
1, the blanking
A general term for a stamping process used to separate materials. It includes: blanking, punching, punching lack, punching groove, cutting, chisel cutting, cutting edge, cutting tongue, cutting and so on
2. Lower profile
It is mainly to cut off a circle of excess material and meet the size requirements of the stamping process
3, cut the tongue
Cut a section of the material, but not all cut, usually cut three sides of a rectangle and keep one side still, the main role is to set the pace.
4, flaring
This process is not common, most of the tubular parts need to end or somewhere out to expand into a horn - shaped situation
5, reducing
In contrast to flaring, it is a stamping process in which the end of a tubular part needs to be shrunk inward or somewhere
6, punching
In order to get the hollow part of the part, the complete material in the middle is separated by the punch and the cutting edge to get the corresponding hole size
7, fine blanking
When the stamping parts need full brightness zone, it can be called "fine blanking" (note: common blanking cutting surface: corner zone, brightness zone, fault zone, burr zone).
8. Full brightness blanking
Different from fine blanking is full - light blanking must be in one - step blanking to get full - light band and fine blanking is not
9. Deep hole blanking
When the aperture in the product is less than the thickness of the material, it can be understood as deep hole blanking, and its stamping difficulty is shown as the punch is easily broken
10. Convex hull
The process of making a bulge on the flat material to meet the requirements of use
11, forming
Many friends understand molding as bending, which is not rigorous. Because bending is a type of molding, molding refers to all the flow of the material process
12, bending
A normal process in which the plate material is plastic deformed through the insert of convex and concave die to obtain corresponding angles and shapes
13 and embossing
This is generally used in the insert of angular bending molding. It is a structure that can reduce the material rebound and ensure the Angle stability by making the material in the bending position out of the bump pit
14, embossing
A process of pressing a special pattern on the surface of a material by punching
15, crimping
Molding process is a process by curling the shape of the product into a circle
16, double holes
The process of turning the inside hole of a stamping piece outward to get a certain height of the side
17, leveling
Mainly aiming at the high flatness requirement of products, the flatness deviation of stamping parts due to stress will require leveling process
18, plastic
When the product molding is completed, when the Angle and shape are not the theoretical size, we need to consider adding a process for fine-tuning to ensure the stability of the Angle. This process is called "shaping".
19, deep drawing
Usually refers to the flat material through the method to get hollow parts of the process known as the drawing process, mainly through the convex, concave die to complete
20. Continuous drawing
Usually refers to a drawing process in which the material in the same position is stretched many times through a pair or several molds in a material belt
21. Thin and deep drawing
Continuous drawing and deep drawing belong to thinning drawing series, which means that the wall thickness of the part after drawing will be less than the thickness of the material itself
22, drawing
The principle is similar to that of a convex hull, which makes the material convex. However, drawing usually refers to automotive parts, which belong to the more complex molding series, and its drawing structure is also relatively complex
23. Engineering die
A set of die in a stamping process can only complete a stamping process of the die collectively
24. Composite module
A set of die in a stamping process can complete two or more different stamping processes of the die collectively
25. Progressive die
A set of die feeding by material belt, will be more than two kinds of process sequence, with the stamping process to the final qualified products of the mold type
