     • Inspect and replace worn dies or tooling.
     • Recalibrate the press brake according to the manufacturer’s guidelines.
     • Ensure that the right tooling is used for the specific bend requirements.
2. Ram Does Not Move
   • Symptoms: The ram fails to engage or moves sluggishly.
   • Causas: Low hydraulic fluid levels, pump failure, or blockages.
   • Soluções:
     • Check and refill hydraulic fluid as needed.
     • Inspect the hydraulic pump for proper operation and replace if necessary.
     • Clear any obstructions in hydraulic lines.
3. Electrical Failures
   • Symptoms: Control panel not responding or error messages displayed.
   • Causas: Faulty wiring, blown fuses, or issues with the control software.
   • Soluções:
     • Inspect all electrical connections for damage or looseness.
     • Replace any blown fuses and reset the machine.
     • Update or reinstall control software if necessary.
4. Uneven Bends or Distortion
   • Symptoms: Finished parts show signs of unevenness or distortion.
   • Causas: Misalignment of the workpiece, improper setup, or tooling issues.
   • Soluções:
     • Check the alignment of the machine and the workpiece.
     • Ensure that all setup procedures are followed accurately.
     • Adjust the tooling to ensure even pressure during bending.
5. Tooling Wear and Tear
   • Symptoms: Tools show signs of excessive wear or breakage.
   • Causas: Improper material handling, incorrect tooling for the job, or lack of maintenance.
   • Soluções:
     • Regularly inspect and maintain tooling.
     • Use appropriate tools for the specific material being processed.
     • Implement a routine maintenance schedule to prolong tooling life.

Preventive Maintenance Tips

• Inspeções regulares: Conduct routine checks on hydraulic, electrical, and mechanical components to catch potential issues early.
• Calibração: Frequently calibrate the machine to ensure accuracy in bending angles and operations.
• Treinamento: Ensure operators are well-trained in machine setup and operation to minimize errors and equipment strain.

Introdução

Dificuldade	Causas	Remédio
Não há óleo na bomba. O controle deslizante não funciona.	Sentido de rotação incorreto da bomba de óleo	Corrija a posição de fase da linha de energia.
Infiltração dos elementos, juntas dos tubos e cilindro de óleo	Anel de vedação danificado ou envelhecido	Troque o anel de vedação.
Tremor de tubo e máquina	Oleoduto vazio devido a óleo insuficiente no tanque de óleo ou malha do filtro de óleo bloqueada	Limpe a malha do filtro ou encha o tanque com óleo até o centro do nivelador de óleo.
Sem pressão no oleoduto	Nenhuma reversão de direção é realizada pela válvula eletromagnética ou o núcleo da válvula eletromagnética, válvula de alívio de pressão ou válvula de enchimento de óleo está emperrado.	Insira corretamente o bujão da válvula eletromagnética para evitar que se solte. Remova e limpe os núcleos das válvulas.
Rastejamento do controle deslizante em movimento descendente	Abertura muito pequena do núcleo da válvula. Temperatura do óleo inferior a 15°C.	Regule a válvula de aceleração e corrija a abertura. Deixe a máquina em marcha lenta para aumentar a temperatura do óleo.
O controle deslizante não consegue parar em uma posição aleatória e escorrega.	O núcleo da válvula está emperrado.	Válvulas limpas.
A velocidade de trabalho do controle deslizante é muito rápida ou muito lenta.	Abertura da válvula de aceleração muito grande ou muito pequena	Regulate the opening size of throttle valve

Conclusão

Understanding the common press brake problems that arise with press brakes troubleshooting can save time and resources.
