Collision-preventing buffer system for large-scale casting mould numerical control processing forming machine

The utility model discloses a collision-preventing buffer system for a large-scale casting mould numerical control processing forming machine, which belongs to the field of a special processing machine tool accessory. The collision-preventing buffer system for the large-scale casting mould numerical control processing forming machine mainly consists of a pressure sensor, a displacement sensor, a spring passive shock damping system, an oil cylinder active damping system, a bearing plate, a base and a rubber gasket; the pressure sensor can be used for judging the striking force; and the displacement sensor is used for judging the current position of a moving system. The novel flexible collision-preventing buffer system integrated with mechanical, hydraulic and electrical techniques is simply structured and is convenient to mount and maintain; the collusion safety of the overall system is monitored through two signals simultaneously, so that the reliability and the safety are greatly increased; due to double composite buffer functions of damping of a damping spring and an oil cylinder, the collision time can be prolonged, so that the collision energy can be transferred into the collision-preventing buffer system out of the moving system; therefore, purposes of protecting the moving system and machine tool parts as well as prolonging the service life of equipment are achieved.
