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 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.

JIS Level 1 accuracy.

Acceptance Procedure:

1. Pre-acceptance at manufacture's site by two parties and before the shipment per Acceptance Form based on technical agreement.

2. Final Acceptance at customer's site by two parties per Acceptance Form based on technical agreement.

Press Installation:

1. The press manufacturer provides the foundation condition diagram of the press, and the user of the press entrusts a professional civil engineering unit to conduct geological survey and foundation design of the installation site based on the foundation condition diagram. The construction of the press foundation is carried out according to the construction drawings provided by the professional civil engineering company.

For more information, please visit Servo Straight Side Double Points Press.

2. When the foundation of the press is completed and meets the installation requirements, the manufacturer of the pressure mechanism shall dispatch an installation instructor; Before installing the press, the user of the press should ensure that the water, electricity, and air required for installation and debugging are in place, and prepare cleaning oil, consumables, transmission lubricating oil, and other items required for installation and debugging.

3. In case of any changes or adjustments to other technical agreements or requirements that have not been fully covered, both parties shall jointly negotiate and determine in a friendly manner.

Technical Support & Training:

1. The manufacture will supply the 7x24 technical support and service to the customer.

2. The instruction manual for the press machine will be provided to the customer after installation and final acceptance.

3. The manufacture is responsible for providing equipment application knowledge and technical training to the buyer's relevant personnel.

-Deliveries

Delivery time will be following the clause form the Sales Contract between two parties.

Press will be shipped after Pre-acceptance at manufacture's site.

Confirmation of installation conditions:

1. Before the installation of the press, the manufacture shall confirm the "Essential Installation Conditions" with the customer in writing. The buyer shall confirm the conditions and sign and stamp before replying.

2. The manufacture shall prepare an installation work plan based on the buyer's installation conditions and status before the installation begins.

3. During the installation process, the customer shall provide the manufacture with the installation tools (including handling tools and lifting tools) as described in the "Essential Installation Conditions".

-Warranty information

1. The warranty period of press is 12 months from the end date of acceptance on customer's site.

2. During the warranty period, the manufacture shall provide spare parts and necessary maintenance guidance free of charge for any abnormal wear and tear of the press components, as well as damage caused by press failures (not operational errors).

3. If the press is damaged due to operational errors or other human factors during the warranty period, the manufacture may negotiate with the customer to collect relevant fees according to the situation.

4. After the warranty period expires, the timeliness of service is the same as within the warranty period. The manufacture is responsible for assisting customer in equipment maintenance (only charging reasonable fees).

5. The manufacture provides lifelong maintenance services and the best priced supply of spare parts for the press equipment.
