What is metal punching processing?
Punching processing is the optimal mechanical processing solution widely applied today. What do you know about metal punching processing ? What are the characteristics of this machining method? The content of this article will help you better understand punching processing technology.
1. What is metal punching processing?
Metal punching processing is one of the solutions of mechanical processing . This is a separation technique, mainly used to process holes in sheet metal. In addition, punching is also suitable for removing excess parts of the material.
The punching method can be performed on many different metal materials. Typically stainless steel, galvanized steel, cold/hot rolled steel, brass, copper, aluminum, etc.
Metal punching and stamping products are widely used in automotive, aviation, electronics, equipment, components, medical technology, etc. Specifically, hand-held and electrical components, bases, bolts. , latches, injection molds, heat pipes, dowels, bolts, hinges, blood glucose test strips, etc., and many other machine parts and products.
2. Characteristics of metal punching processing
This mechanical processing solution has the following main characteristics:
Cost effective to make holes in sheet metal with medium to high grade.
Multiple holes can be made in the metal sheet at the same time.
Punching tools are usually made from steel and carbide.
The punching process is quick, decisive, and highly effective
Workpieces in punching are usually in the form of flat sheets or rolls.
3. Advantages of metal punching processing
Product quality is stable. Perforated shape is highly aesthetic.
Applicable to mass production processing thanks to the ability to make multiple holes in sheet metal of the same size and shape.
Save machining time, take less labor.
Limit the production of waste products, bring high economic efficiency.
4. Techniques in metal punching processing
Flat punching processing
Flat punching is the process of shaping an object using a flat tool or a stamping machine. The raw materials will move horizontally while the press is pushed down vertically to do the punching.
Flat punching processing technique is used in cases such as material coming from a single sheet, thick products, small orders, etc. This technique is highly cost effective.
Rotary punching processing
Punching tools are mounted directly in the bearings, high precision or adjustable on 2 cylinders. The raw material is fed between the 2 rolling cylinders at very high speed to make the shaped products. The advantage of rotary punching technique is high precision, less raw material than flat punching.
Rotary punching machining is applied when stamping thin products, large quantities, designs with tight tolerances, etc. This technique offers high productivity, reduced energy consumption, low vibration, so less production is produced. noise.
In general, both techniques have advantages and disadvantages. Accordingly, depending on the intended use, you should choose the appropriate technique to create the desired products.
