the upper connecting pipe 114 is sealed and screwed into the valve body of the electric valve 112, and the other end of the upper connecting pipe 114 is sealed and screwed into the air inlet pipe orifice 101 of the air cylinder 10, so that the electric valve 112 and the air cylinder 10 are connected and fixed;
the positions and the number of the air cushion devices 1 to be laid out are determined according to the weight and the plate surface size of the plate materials, the connecting plates 30 of the air cylinders 10 of a plurality of air cushion devices 1 are respectively placed in the square units 100 of the supporting frame 2, the lower surfaces of the connecting plates 30 are supported on the four corner supports 7, the corner support connecting holes 431 of the connecting plates 30 are aligned with the corner support holes 71 of the four corner supports 7 in the center, and the third bolts 43 respectively penetrate through the corner support holes 71 of the corner supports 7 and are fastened by the third nuts 430, so that the air cushion devices 1 and the supporting frame 2 are fixed into a whole.
The lower end of the valve body of the electric valve 112 of the air cushion device 1 is sealed and screwed into the lower connecting pipe 113 to be connected with a compressed gas source.
An output control circuit of the distance sensing device is connected to an electric actuator 111 of an electric valve 112.
In the processing process, the processing method comprises the following steps:
placing a plate to be processed on a platform of a support frame 2 by using a crane;
opening a compressed gas source to enable a pipeline at the lower part of a valve body of each electric valve 112 to be filled with compressed air, and opening a power supply of each distance sensing device to enable each distance sensing device to work;
when the plate to be sheared is covered above the distance sensor, the distance sensor transmits sensed information to a controller, the controller controls the electric valve 112, and the electric actuator 111 of the electric valve 112 opens the valve body;
compressed air enters the inner cavity of the air cylinder 10 through the valve body, and the bellows section 32, the diaphragm 51 and the bell mouth 31 of the elastic connector are lifted upwards along with the pressure rise;
after the sealing ring 55 of the bell mouth 31 contacts with the bottom surface of the plate to be sheared, the contact surface between the deformation of the bell mouth 31 and the bottom surface of the plate to be sheared is increased, and the sealing ring 54 of the bell mouth 31 contacts with the bottom surface of the plate to be sheared along with the continuous rising of the pressure so as to increase the tightness between the bell mouth 31 and the bottom surface of the plate to be sheared.
At this time, as the pressure difference between the lower and upper compressed air of the diaphragm 51 increases, the vent belt is opened by the compressed air, so that the compressed air enters the bell mouth 31 through the vent belt and maintains a minute pressure difference;
the pressure of the compressed air inside the sealed bellmouth 31 increases, which can act on the underside of the sheet to be sheared, forming an upward lifting force on the sheet, which can counteract the weight of the sheet to be sheared;
under the combined action of the air cushion devices 1, the bottom surface of the plate to be sheared leaves the supporting frame 2;
at this time, the gravity of the plate to be sheared is mainly lifted by the upward force formed inside the bell mouth 31, and the plate to be sheared is moved in all directions with little effort due to the small friction with the sealing part of the bell mouth 31. Therefore, when the plate to be sheared is moved and positioned, the labor intensity can be reduced, the working efficiency can be improved, and automatic and accurate feeding can be conveniently realized.
When the plate to be sheared does not completely cover a certain air cushion device 1, the distance sensing device does not output control current to the electric valve 112, and compressed air does not enter the air cushion device 1, so that the plate does not participate in work.
Along with the movement of the plate to be sheared, the distance sensing device of the air cushion device 1 below the plate to be sheared automatically detects and controls the on-off of the compressed gas of the electric valve 112, so that the whole feeding device has automatic control performance, along with the movement of the plate to be sheared, the supporting force on the plate to be sheared is not reduced, the leakage of the compressed air can be avoided, and the energy is saved.
While the invention has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the invention and are intended to be within the scope of the invention as claimed.
