The plate is pressed down continuously along with the lower pressing shaft 2-1, the bending degree of the middle position is increased continuously, after the plate enters the vertical sliding groove 1-2 along with the lower pressing shaft 2-1, the two ends of the plate are in a state of being vertically upward and parallel to each other, along with the continuous descending of the position of the lower pressing shaft 2-1, the lower pressing shaft 2-1 is contacted with the upper bearing plate 3-11 through the plate, the upper bearing plate 3-11 transmits the pressing power transmitted by the lower pressing shaft 2-1 to the lower bearing plate 3-13 through the connecting plate 3-12, and the lower bearing plate 3-13 compresses hydraulic oil in the oil storage cabin 1-3.
The lower bearing plate 3-13 compresses the hydraulic oil in the oil storage tank 1-3 under the continuous downward pressing of the lower pressing shaft 2-1, so that the hydraulic oil enters the transverse sliding grooves 1-1 at two sides of the vertical sliding groove 1-2 through the oil pipe 1-8, the two groups of extrusion plates 3-2 are respectively pushed by the hydraulic oil to inwards extrude and bend two ends of the plate, the oil quantity of the hydraulic oil entering the transverse sliding grooves 1-1 is continuously increased along with the continuous downward pressing of the lower pressing shaft 2-1, the two groups of extrusion plates 3-2 are continuously extended outwards along with the continuous descending of the lower pressing shaft 2-1, the bending degree of the two groups of extrusion plates 3-2 to two ends of the plate is continuously increased, after the lower bearing plate 3-13 is contacted with the inner lower end surface of the oil storage tank 1-3, the hydraulic oil in the oil storage tank 1-3 enters the transverse sliding grooves 1-1 at two sides, the extension amount of the extrusion plates 3-2 in the transverse sliding groove 1-1 is maximized, the bending degree of the extrusion plates 3-2 to the plate is maximized, the two groups of extrusion plates 3-2 and the upper bearing plate 3-11 are mutually matched to form a circular space for bending the plate, and the two groups of extrusion plates 3-2, the upper bearing plate 3-11 and the lower pressing shaft 2-1 are mutually matched to form an annular space for bending the plate.
The plate is continuously bent along with continuous pressing of the pressing shaft 2-1, after the pressing shaft 2-1 is contacted with the upper bearing plate 3-11 through the plate, along with continuous pressing of the pressing shaft 2-1, the two groups of extrusion plates 3-2 continuously extrude and bend two ends of the plate, when the lower bearing plate 3-13 cannot move in the oil storage cabin 1-3, namely the bearing plate 3-1 cannot move in the vertical sliding groove 1-2, an annular space for bending and forming the plate is formed, and bending of the plate is completed simultaneously.
When the upper pressure bearing plate 3-11 moves downwards, the upper pressure bearing plate 3-11 compresses the compression air bags 1-6 on the two sides, when the compression air bags 1-6 are stressed and compressed, air completely enters the compression cabin 1-5 and is compressed into high-pressure air, when the external force applied to the compression air bags 1-6 is reduced, the high-pressure air in the compression cabin 1-5 enters the compression air bags 1-6, and the high-pressure air generates upward pushing force on the upper pressure bearing plate 3-11 in the process of releasing pressure.
When the lower bearing plate 3-13 moves downwards in the oil storage cabin 1-3, the lower bearing plate 3-13 compresses a plurality of groups of springs 1-7, the plurality of groups of springs 1-7 generate internal energy and release heat when being compressed, the plurality of groups of springs 1-7 release heat simultaneously, so that the temperature of hydraulic oil in the oil storage cabin 1-3 is increased, the volume of the hydraulic oil is expanded, and when the volume of the hydraulic oil is expanded and the extrusion plate 3-2 is pushed, the plate blocks the extrusion plate 3-2, so that the pushing force of the hydraulic oil on the extrusion plate 3-2 is increased.
After the plate is bent and formed, the lower pressing shaft 2-1 moves upwards under the pushing of the hydraulic press 2-2, the lower pressing shaft 2-1 generates acting force on the extrusion plates 3-2 at two sides above through the plate when rising, the stress analysis is carried out by taking the extrusion plate 3-2 at the left side as an example, when the extrusion plate 3-2 at the left side receives the pushing force FX upwards obliquely from the lower pressing shaft 2-1, the pushing force FX is decomposed into an upward pushing force F1 and a leftward pushing force F2 by the extrusion plate 3-2, when the extrusion plate 3-2 is pushed by the lower pressing shaft 2-1, the rightward pushing force of hydraulic oil received by the air bag 3-21 is reduced and the pressure is released, and the left pushing force F3 of the air bag 3-21 is received by the extrusion plate 3-2 through the mutual matching of the air bag 3-21 and the compression plate 1-4, f2 and F3 are added to be larger than F1, so that the extrusion plate 3-2 overcomes the friction force F between the extrusion plate 3-2 and the transverse sliding chute 1-1, the extrusion plate 3-2 can move to the left in the transverse sliding chute 1-1 and contract into the transverse sliding chute 1-1, and the lower pressing shaft 2-1 carries the bent plate to move above the upper base 1 through contraction of the extrusion plates 3-2 on the left side and the right side.
When the left and right groups of extrusion plates 3-2 contract inwards, hydraulic oil returns to the oil storage cabin 1-3 again through the oil pipe 1-8 by extrusion of the extrusion plates 3-2, the stress analysis is performed by taking the ascending groove on the left side of the pressure bearing plate 3-13 as an example, when the lower pressing shaft 2-1 starts to ascend, the hydraulic oil enters the oil storage cabin 1-3 through the oil pipe 1-8 by extrusion of the extrusion plates 3-2 and generates an oblique upward pushing force FX2 for the ascending groove, and the ascending groove on the left side performs stress decomposition on the pushing force FX2 to be decomposed into a rising pushing force F4 and a rightward pushing force F5; the right-side ascending groove is subjected to stress analysis in the same way and is divided into a ascending pushing force F6 and a leftward pushing force F7, F5 and F7 are mutually offset, so that the lower pressure bearing plate 3-13 is only subjected to upward pushing force F4+ F6 by the ascending groove, when the lower pressure bearing plate 3-13 is subjected to the pushing force of the hydraulic oil, the spring 1-7 releases elastic potential energy, the lower pressure bearing plate 3-13 is quickly ascended in the oil storage cabin 1-3 by the mutual matching of the elastic potential energy and the pushing force F, the lower pressure bearing plate 3-13 transmits ascending power to the lower pressure shaft 2-1 through the connecting plate 3-12, the upper pressure bearing plate 3-11 and the plate, and the pushing force of the lower pressure shaft 2-1 on the extrusion plate 3-2 is increased.
When the upper bearing plate 3-11 is pushed by the lower bearing plate 3-13, the compression of the compression air bag 1-6 is reduced, so that the high-pressure air in the compression cabin 1-5 is fed into the compression air bag 1-6, and the upper bearing plate 3-11 is pushed upwards.
