The utility model discloses can improve the application scope, the installation of the tensile pad of shutting simple, rational in infrastructure.
The utility model provides a technical scheme that its technical problem adopted is: a slow lifting device for a locking stretching pad of a mechanical press is characterized in that a branch pipeline is arranged on a main pipeline of an original device, and the branch pipeline controls air inlet speed so as to control lifting speed of the stretching pad; the stretching pad is connected with a first gas tank through a main pipeline, a gas control reversing valve is arranged on the main pipeline, branch pipelines are arranged on two sides of the gas control reversing valve on the main pipeline, a second electromagnetic reversing valve, a pressure reducing valve and a one-way valve are sequentially arranged on the branch pipelines, the pipe diameter of each branch pipeline is 1/10 of the pipe diameter of the main pipeline, the gas control reversing valve is connected with a second gas tank through the first electromagnetic reversing valve, the second gas tank supplies gas for the gas control reversing valve, and the gas control reversing valve is connected with a third electromagnetic reversing valve.
When the stretching pad moves downwards under the action of the sliding block, the third electromagnetic directional valve is in an open state, and the pneumatic control directional valve is controlled to be in an exhaust state. When the stretching pad is at the lower limit position, the third electromagnetic directional valve is in a closed state, and the stretching pad is in a locking state at the moment, so that the die is convenient to repair. When a mould is ground, the stretching cushion needs to be lifted slowly, the first electromagnetic directional valve controls the air control directional valve to be in an exhaust state, the third electromagnetic directional valve is in a disconnection state, the second electromagnetic directional valve is opened, the pressure reducing valve is set according to working pressure, the one-way valve prevents gas from flowing back, the first gas tank inflates the stretching cushion, and the speed is effectively controlled because the pipe diameter of the branch pipe is 1/10 of the main pipeline. When the die grinding process is finished and the stretching pad needs to be quickly reset, the first electromagnetic reversing valve is reversed, the pneumatic control reversing valve is switched on, the air inflation amount is increased, and the purpose of quickly returning the stretching pad is achieved.
The utility model has the advantages that: the utility model discloses can avoid air cushion return speed single problem, lower limit position can block and stop, guarantee safety, can realize freely switching of slow speed and quick return stroke. Has the function of reliably and accurately controlling the action of the air cushion.
