Control pipeline used for braking system of servo press

The invention discloses a control pipeline used for a braking system of a servo press. The control pipeline comprises a pneumatic pump, a filtrator, an energy accumulator, a filter, a liquid level relay, a motor, a pressure adjusting valve set, a gear pump and an oil tank, the motor and the gear pump are connected through a coupling, the gear pump and the pneumatic pump are parallelly connected and then connected with the oil tank, the filtrator is connected with an oil inlet of the pressure adjusting valve set, an oil outlet of the pressure adjusting valve set is connected with double safety valves and a brake, a pressure sensor is arranged between the safety valves and the brake, a pressure sensor is mounted on the pressure adjusting valve set, the whole system is connected with the energy accumulator, and the pressure adjusting valve set is provided with an overflow module, a pressure adjusting module and an unloading module. By the control pipeline, pressure of the system can be increased quickly, and pressure stability of the system can be guaranteed; the safety valves are adopted to control the brake, so that safety coefficient of the brake is increased; the system is simple in composition and high in dynamic performance, pressure of the system can be stabilized within a working range, maintenance quantity is reduced, and working efficiency of the servo press is guaranteed.
