introduction of servo press machine working modes

Servo press is more smart than general crank type press machines. Servo control system is programmable for different stamping parts. This article is to introduce the most popular working modes of a servo press.

Crank motion

It is same as a general crank press. But the servo motor is few electricity consumptions. Servo press works quieter. Operator can set the press speed through the system. This mode is suitable for normal piercing, blanking and bending process.

Slow at top for automation

Press often works with coil strip feeding machines or transfer system. It is easier to match the feeding and transfer system if the slider can run slower near the top dead point. This mode is also called as feeder mode. Several presses work as an automatic line with help of transfer system between the presses. This mode is help for match the speeds of different presses.

Reduce spring back

It is also called as pulse mode. The slider runs as spring back many times before bottom dead point. This is better to release the material stress after stamping. It can achieve better drawing performance, such as tin cans and filter houses deep drawing.

Higher speed pendulum

Slider runs with short stroke length and it does not back to TDC. This mode provides press higher efficiency.

FWD/REV, Stop before BDC

This mode is also called as embossing mode. Operator can set the speed changing points and the stroke speeds. Slider will stop before bottom dead point to keep pressing on the stamping parts. It can avoid material spring back. Suitable for logo embossing and coins production.

Coin three times

It is also called as forging mode. Suitable for hardware production. Such as wrench and knife.

Dewell above BDC

Press slider can stop for a while above BDC. Some parts need heating before stamping and forging. The slider can wait for material heating and then press down. For example, the phone house cover of material Mg.

Link motion

The servo press works like a hydraulic press. The slider fast approach down, slow pressing and fast return. It is suitable for deep drawing process. The working efficiency is much higher than hydraulic press.

Knuckle motion

Like a knuckle joint press. Suitable for powder and cold forging.
