E21 press brake failure causes and solutions - sometimes the main motor automatically stop, heat relay, circuit breaker protection E21 press brake failure reasons: 1. Proportional pressure valve and main pressure reducing valve are stuck, and the machine has been pressurized; 2. The filter element is blocked, the oil output is not smooth, and the oil pump pressure is always high; 3. The oil has been polluted for too long time; 4. Poor oil quality; 5, circuit breaker, heat relay… Read More »E21 press brake failure causes and solutions - sometimes the main motor automatically stop, heat relay, circuit breaker protection

Fault one: no pressure in hydraulic system 30t hydraulic press brake . 1. Whether the solenoid coil of the proportional relief valve is energized and whether the voltage of the proportional solenoid coil meets the requirements. For the above reasons, please check the related electrical reasons. 2. Check whether the cartridge valve is jammed or the main spool is jammed, and the damping hole is blocked. If it is for the above reasons, please remove the overflow valve, clean it,… Read More »How to solve the common faults of 30t hydraulic press brake

Bending press brake machine by the fuselage, torsion shaft, slider, stroke adjustment, front supporting frame, rear retaining frame, mold, hydraulic system, electrical system and other nine parts. In the use of hydraulic bending machine by wire on the coil electricity, electricity on the pressure plate to produce gravity, so as to achieve the clamping plate and base between the thin plate.

When we buy CNC bending machine, often do not know what is the appropriate CNC bending machine, then how to choose CNC bending machine? How do you avoid being fooled? Bending machine manufacturer to introduce you to buy CNC bending machine five steps and skills: 1: First of all, according to their own demand parameters, determine the specifications of the purchase of the machine, but also take into account the need to expand the scale of the enterprise to leave… Read More »Five steps and tips for buying a CNC bending machine

Fault one: the CNC system  bending machine is abnormal This failure is usually caused by software, misoperation during operation or frequent abnormal shutdown can lead to file loss, so that the software does not work properly. You can judge according to the system prompts, and then decide whether to reinstall the software. Fault two: sliding block motion failure CNC system bending machine The slider movement of the bending machine can be divided into four processes, starting back to zero, fast… Read More »Common faults and solutions of CNC system bending machine
