Description

Press brake piston motion detection device

Technical Field

The utility model relates to a press brake piston motion detection device is applied to the mechanical press trade, belongs to mechanical engineering technical field.

Background

The brake is an important functional component of the transmission part of the press, and the brake can rapidly stop the movement of the sliding block when the clutch is disengaged. In order to overcome the work energy of transmission, the braking force of the brake is provided by a spring and is released by compressed air. Under the action of the spring force, the pressing plate presses the friction plate of the brake, and the brake torque is generated by the friction plate. The compressed air overcomes the spring force through the piston, and when the cavity formed by the piston and the cylinder is filled with air, the piston can drive the pressing plate to separate the pressing plate from the friction plate, so that the purpose of stopping braking of the brake is achieved. Because the inner cavity of the piston is regularly filled with/released with gas, the friction plate and the pressing plate can be in a disengaged and combined motion state for a long time, whether the piston in the brake is in place or not is an important index for whether a balanced brake can meet the safe use or not, and the brake performance parameters of the brake cannot be acquired because the brake piston does not have motion detection all the time.
