What is a metal stamping press machine?

The technical definition of metal stamping is that it is a cold forming process that uses high force and/or speed to permanently replace the shape of a piece of metal. In the case of sheet metal stamping, the workpiece is sheet metal. Anyway, metal stamping machines can also be used for wire and other types of metal.

Simply put, the machine uses a die to make the shape of the metal. Brass, steel, and aluminum are some of the most generally used metals. The stamping process may look different depending on what is being produced, but the shapes are generally made from sheet metal, placed on a stamping die and put into a press.

How does a stamping press machine work?

The general operation of a metal stamping is easy: put the material into a machine that can immediately apply many tons of force and use them to press the metal object into the shape you want.

Sheet metal stamping machines can generally perform many different processes.

Forging round metal

This is similar to flattening because it makes the workpiece thinner, but this process is generally used for wire rather than sheet metal. Profile-forged wire makes one end narrower so it can fit more simply into an opening.

Flattering metal

One of the most general operations of a stamping machine is to flatten a metal objective. This can be performed to smooth the object or to make it thinner at a certain point for other objectives.

Perforated metal

Instead of just flattering the metal, the dies and tools of a sheet metal press can pierce a piece of metal. This makes an opening that can be used to join multiple pieces.

Casting metal

Instead of punching a little hole in the piece of metal, the dies and tools of a sheet metal stamping process can be used to punch the sheet metal into a specific shape.

Since sheet metal stamping machines process chill metal pieces that have not yet been given ductility, they must rely on big force to get the work done–which is why these machines are generally equipped with very strong motors.

Types of metal stamping presses

Stamping presses can be divided into 3 key classifications based on how they operate:

Hydraulic stamping presses

Hydraulic stamping presses trust on pressurized hydraulic fluid to produce the pressing force. They feature adjustable stroke and speed features. Pressing capacities range between 20-10,000 coins. They are generally employed for little volume production runs involving complex products and parts.

Mechanical stamping presses

Mechanical stamping presses utilize a motor linked to a mechanical flywheel to power stamping operations. They generally provide pressing speeds between 20-1,500 strokes per minute and pressing capabilities ranging between 20-6,000 tons. They are generally used for high-volume progressive and transfer stamping operations.

Mechanical servo stamping presses

Mechanical servo presses use top capacity motors run by a link-assisted or direct drive system. They are generally used to produce complex parts in shorter periods than would be easy with hydraulic or mechanical machines.

Applications in different industries

Industries for sheet metal stamping firms include

• Industrial machinery

• Automotive

• Consumer electronics

• Electrical

• Aerospace

• Medical devices

• Telecommunications

The automotive industry is a big market for the metal stamping industry; anyway, the use of metal fabrication in the consumer electronics industry is rising in this technology generation.

This means that almost all firms that use consumer electronics in the workplace rely on items made by metal stamping machines.

Other little industries that produce items such as household and jewelry appliances can mass produce products with the help of metal stamping presses.

What is the stroke rate per minute for stamping press machines?

Mechanical presses use an electric motor which spins a belt linked to a flywheel. This is transferred via a series of gears. These gears drive the ram up and down. To begin the press, the flywheel is linked to a clutch and brake system which permits the flywheel to spin without actuating the ram at all. These mechanical systems generally run a lot quicker than others, with most presses capable of stamping the par 40-80 times in a minute. This rate is known as stroke per minute and it is an important factor in progressive tool design as it dictates how fast you can make your product.
