Stamping is a machining process in which a stamping die installed on a stamping machine applies punching pressure to a material, causing it to separate or plastic deform, and then obtain the required precision stamped parts. The vast majority of stamping is processed at room temperature, also known as cold stamping. Here are the types of stamping processing to let you know the world of stamping.

1. Punching

Separate the waste from the raw material or workpiece along the closed shape, and obtain the required holes in the material or workpiece, generally including round holes, square holes, waist holes, and special-shaped holes.

2. Blanking

The raw materials are separated by stamping along the closed summary, and the materials in the summary line are the required stamping parts. The more common products for blanking are: iron sheets of various shapes, baffles, etc.

3. Incision

Cut notches at the edge of the material or workpiece.

4. Cut the tongue

It is the material that is completely separated along the open summary part rather than completely separated, and makes the separated materials reach the required spatial position. Tongue-cutting products are typically mosquito coil racks and some commonly used spring blades.

5. Trimming

The edge of the trimmed workpiece is to satisfy the requirements of shape and scale.

6. Cut off

The materials are separated by stamping along the open generalization to obtain the required precision stamping parts.

7. Bending

Make the raw materials along a certain axis, stamping and bending into a certain angle. Can process a variety of complex shapes of bending parts. Bending is often a common type of stamping processing technology, such as brackets, hooks, fixed parts, furniture corner codes, door and window corner codes, etc.

8. Drawing

Deform the plate material or workpiece into an open hollow part, or an open hollow part to further change the shape and size. Common stamping deep parts are: pots and pans, sinks, cups, cans, bottle caps, metal shells, car covers in kitchen supplies, etc.

9. Bulging

Expand the hollow workpiece or tubular part along the radial direction to increase the radial dimension as required.

10. Ups and downs

After the elongation and deformation of some materials, the workpiece forms a partial depression or bulge.

11. Outer edge flanging

Turn the outer edge material into a short side along the shape curve.

12. Inner edge flanging

Turn the material at the edge of the inner hole vertically along the closing curve.

13. Shrinkage and diameter reduction

Reduce the diameter of the mouth or middle of the hollow workpiece or tubular part. Narrowing is generally used for the docking of steel pipes.

14. Flare

It is the opening of the hollow workpiece or tubular part that expands outward to form a product with a larger mouth diameter.

15. Curling edge

Roll the material at the edge of the opening of the hollow into a circle along the closing curve

16. Smaller plastic surgery

Flattening is the flattening of flat parts with arch bending or warping to improve their flatness. Shaping is the deformation of parts of the material by stamping to change the shape and size of the formed workpiece in a small amount to ensure the accuracy of the workpiece.

After the introduction of these 16 processing types, it is possible to gain a clearer understanding of what kind of processing technology stamping is, and it is also possible to effectively identify which products are processed through the stamping process in daily life.
