Comment gérer le manque de pression dans la presse plieuse

How to solve the problem of no pressure on the bending machine

Bending machines are the most common machines in the sheet metal industry. During long-term use, the machine may fail to apply pressure. In this article, we will analyze the causes and solutions of such problems for you.

1. Problèmes du système hydraulique

(1) Huile hydraulique anti-usure insuffisante ou mauvaise qualité d'huile.

The hydraulic system needs sufficient hydraulic oil to work properly. If the hydraulic oil is too little or the oil quality is poor, it will affect the normal operation of the system and cause the bending machine to fail to pressurize. Check the hydraulic oil level and oil quality in time, and add or replace the hydraulic oil in time.

(2) The oil pump fails. The oil pump is the core component of the hydraulic system. If the oil pump fails, it will affect the normal operation of the system and cause the bending machine to fail to increase pressure. The hydraulic pump needs to be inspected, repaired or replaced.

(3) Failure of the valve group.

The function of the valve group is to control the flow, pressure and movement of the machine in the hydraulic system. If the valve group fails, it will affect the normal operation of the system and cause the bending machine to be unable to pressurize. The hydraulic valve needs to be checked, repaired or replaced.

2. Défaillance du système de transmission

(1) Défaillance d'un composant mécanique.

The transmission system of the bending machine is composed of multiple mechanical components. If any mechanical component fails, it will affect the normal operation of the system and cause the bending machine to be unable to pressurize. The faulty mechanical component needs to be checked, repaired or replaced.

(2) Défaillance du capteur.

The sensor of the bending machine is the input and output device of the control system. If the sensor fails, the control system will not work properly, resulting in the bending machine being unable to pressurize. The faulty sensor needs to be checked, repaired or replaced.

3. Problème de fuite du joint de cylindre

When the cylinder seal is aged and worn, the cylinder will leak, resulting in the machine being unable to pressurize. The cylinder seal needs to be checked or replaced.

4. Défaillance du système de contrôle de l’équipement.

If the control system of the bending machine fails, the equipment will not work properly, resulting in the bending machine being unable to pressurize. The equipment control system needs to be checked and repaired.

5. Mauvais fonctionnement de l'opérateur.

If the operator operates improperly, the bending machine will be unable to pressurize. The training and management of the operator needs to be strengthened to avoid misoperation.

6. Blocage du filtre.

When the filter at the oil inlet in the oil tank is blocked, the oil pump will fail and the machine will be unable to pressurize. The filter needs to be cleaned regularly.

In short, the failure of the bending machine to pressurize may be caused by many reasons, which need to be investigated and solved from multiple aspects such as hydraulic system problems and transmission system failures. Only by ensuring the normal operation of the equipment can we better complete the processing tasks and improve production efficiency.
