Metal Deep Drawing Process

Drawing is a process of forming metal sheets into cylindrical or box shapes by stamping, circular drawing or metal forming. Usually, deep drawing is carried out on the wrinkle proof plate of the double action press, which can effectively prevent the raised edge from wrinkling when it is pulled into the mold. Unlike other drawing processes, the drawing depth can exceed the original diameter of the blank.
Under the pressure of the press, the drawing die is used to process flat blank or hollow process parts into open hollow parts. It is one of the basic stamping processes. It can not only process rotary parts, but also process thin-walled parts with complex shapes such as box parts.
Dyeing can be divided into non-dyeing and dyeing. The wall thickness of the front parts is basically unchanged compared to the blank before drawing. Compared with the sheet before drawing, the wall thickness of the sheet after drawing has obvious changes. This kind of thinning is required by the product, and the features of the part are thick bottom and thin walls. In practical production, continuous thin drawing is widely used.
The die used for drawing is called the drawing die. The structure of the drawing die is relatively simple. Compared to the blanking die, the working part has a larger fillet. High surface quality requirements. The clearance between the punch and the die is slightly greater than the thickness of the sheet.

What is Deep Drawing Stamping?

Drawing and stamping is a manufacturing process that uses dies to stretch materials into final shapes by pressing metal sheets into dies. The main benefit is that it can create complex shapes quickly and efficiently. If you need metal parts with a lot of curves or complex details, this stamping may be an ideal choice. Because it can adapt to almost any design limitation, and deep drawing parts are more durable than stamping parts, because they will be slightly worn in the production process.

Sheet Metal Stamping Process

The sheet metal stamping process is to press the hot-rolled or cold-rolled steel plate into the shape required for manufacturing parts. This technology allows a large number of parts to be produced at the same time, but it can also lead to the scrapping of about 15% of raw materials. This kind of equipment used in this method requires less space than other methods. Therefore, if your space is limited, this type of manufacturing may be the most suitable for your business. When selecting the sheet metal stamping method, three types of dies are mainly used – cutting, punching and bending.

Cutting includes cutting a part from a metal plate. This is done by striking the metal plate with the mold, which cuts it into the desired shape. The edges of stamping parts will have burrs, so they need to be drilled or machined before use.

Stamping is the process of placing a metal plate between two molds and pressing them together to make a hole in the metal plate.

Bending is the use of die pressure to deform the metal. This type of stamping is usually used to make parts with curves.

Considerations for Deep Drawn Stamping

When considering deep drawing to meet your manufacturing needs, you should pay attention to the following points:

Reduce material waste: compared to other metal forming processes, deep drawing uses more base materials, significantly reducing material waste.

Measurement is critical: it is not only important to ensure accurate mold dimensions, but also important to consider material thickness and required measurement values. Incorrect measurement will lead to thin walls and inaccurate dimensions.

Draft and Taper: Due to the basic manufacturing process of deep drawing, some drafts and tapers at the top of the part are unavoidable. This should be considered at the initial design stage.

Different material thicknesses: Deep drawing parts usually have different thicknesses, with thinner walls and thicker bases. This can be mitigated by tools after the wire drawing process is completed.

Benefits of Deep Drawn Stamping

equipped with automatic feeding to improve efficiency. In fact, deep drawing is one of the fastest manufacturing methods in mass production. Deep drawing assemblies can also be created in one piece, reducing the need for additional assembly. This has the added benefit of seamless construction, which is ideal for waterproof or airtight applications.

Deep drawing has high universality, can be used to manufacture complex and fine parts, and has high accuracy and repeatability. More importantly, deep drawing parts have very strong strength because of the great compression applied to the metal during the forming process. The basic structure of the deep drawing metal is usually highly compressed into a very hard crystal structure.

Cylindrical deep drawing piece

The application of stretch pieces is very extensive, and we can often see it in our life. Drawing parts manufacturers need to understand the drawing characteristics of drawing parts during stamping, so as to better control production. Cylindrical strip is a common metal stamping strip. Next, Zhejiang Baifudu Precision Stamping introduces the tensile characteristics of the cylindrical stretch piece. 1. Tensile coefficient and tensile time of cylindrical tensile parts. Tensile coefficient m refers to the ratio of cylinder diameter (or semi-finished product diameter) before and after stretching to the blank diameter (or semi-finished product diameter).

2. The partially stretched stamp can only be formed once, and its stamping coefficient is the ratio of the diameter of the cylindrical portion of the stamp to the diameter D of the blank.

3. Some stretch pieces need to be punched several times before forming. The tensile coefficient can be used to indicate the degree of deformation of the material during stretching. The smaller the value of the tensile coefficient m, the greater the degree of deformation.

4. From the point of view of reducing production costs and improving economic benefits, the better the stretching time, the lower the stretching coefficient of each stretch. However, the smaller the m value, the greater the deformation, and the greater the pmax value. When m decreases to a certain value, the pmax value will reach the tensile strength of the dangerous area σ b. This will lead to the rupture of the hazardous area. In deep tension, the tensile coefficient corresponding to the condition that the dangerous area is at the edge of the tensile crack is called the ultimate tensile coefficient (or the lower limit of the tensile coefficient), which is recorded as min. The value of the ultimate tensile coefficient depends on the upper limit of tensile stress in the force transfer area of the cylinder wall and the strength of the dangerous part. Any factor that can reduce the upper limit of tensile stress in the force transmission area of the cylinder wall or increase the strength of the dangerous part will help reduce the ultimate pullout coefficient.

5. The higher the material strengthening rate ( σ s/σ The smaller the b ratio, the greater the value of n and D), and the smaller the value of the ultimate tensile coefficient. The greater the thickness of the anisotropy index, the smaller the ultimate tensile coefficient.
