as shown in FIGS. 1-5, the cylinder body 18 is a welded structure and is divided into a cavity A18-1 and a cavity B18-2, through holes 8- | 16, 4- | 6 and 7- | 5 are distributed on the inner wall in a graded manner, the cavity A is communicated with the cavity B, and the pore size is sequentially reduced; hole spacing t1> t2> t3> t4> t5> t6> t7> t 8. The piston 5 is a forged piece, and 6-phi 6 through holes are distributed on the piston head and are used for communicating the surface F with the surface D.
As shown in fig. 1-5, the piston 5 is installed in the cavity a of the cylinder 18, the material blocking block 1 is fixed at the end of the piston rod of the piston 5 by the first screw 3 and the first spring washer 4, and the anti-rotation pin 2 is used for preventing the material blocking block 1 and the end of the piston rod from rotating relatively. The cylinder opening 15 is arranged in a cavity A of the cylinder body 18, a hole retainer ring 9 is embedded in an inner hole of the cylinder body 18 and used for fixing the cylinder opening 15 and preventing the cylinder opening 15 from axially moving, an O-shaped sealing ring 12 is arranged between the outer diameter of the cylinder opening 15 and the inner hole of the cylinder body 18 and plays a role of static sealing, and a dust-proof ring 10, a U-shaped sealing ring 11 and a guide ring 16 are arranged in the inner hole of the cylinder opening 15 and used for dust prevention, dynamic sealing and guiding of a piston rod of the piston. The piston head of the piston 5 is provided with a hole-used GREEN 17 for dynamic sealing and guiding of a piston head, a spring 19 is arranged in a cavity A (piston head cavity of the piston 5) of a cylinder body 18, one end of the spring 19 is contacted with the cylinder bottom surface of the cavity A of the cylinder body 18, and the other end of the spring is contacted with the piston head end surface of the piston 5.
As shown in fig. 1-5, the flange 6 is mounted on the right end face of the cylinder 18 by a second screw 7 and a second spring washer 8, oil 20 is injected through an oil injection screw hole on the outer wall of the cylinder 18 and flows into the cavity a through the cavity B of the cylinder 18, a preset space is reserved to ensure that the oil 20 can flow into the cavity B from the cavity a when the spring 19 is compressed. After the hydraulic oil is injected, the screw plug 13 and the combined sealing gasket 14 are installed on the outer wall of the cylinder body 18. The whole buffering mechanism is fixed in front of the plate 21 in the advancing direction through the flange 6.
As shown in the figures 1-5, the working process is that the edge of a plate 21 in the process of moving touches a material blocking block 1, a piston 5 moves leftwards under the action of external force, a spring 19 is compressed, the volume of a cavity A (a piston head cavity of the piston 5) of a cylinder 18 becomes small, oil flows into a cavity B through holes 7-phi 5 in sequence, throttling holes are distributed in a graded manner, the flow is small, and the oil pressure is large; meanwhile, oil in the cavity B of the cylinder body 18 sequentially passes through the 8-phi 16 hole and the 4-phi 6 hole, and flows into the surface F and the piston rod cavity from the surface D of the right end of the piston head of the piston 5 through the 6-phi 6 through hole, so that the volume of the piston rod cavity is increased, the flow rate is high, the oil pressure is low, the plate 21 is blocked due to the fact that pressure difference exists and the compression spring force needs to be overcome, and buffering is achieved. When the hole on the piston head of the piston 5 exceeds one phi 5 through hole on the innermost edge of the cylinder body 18 by the aid of the GREEN ring 17, a cavity A of the cylinder body 18 (a piston head cavity of the piston 5) forms a closed cavity, oil cannot be compressed, the piston 5 stops moving, the plate 21 is braked and positioned, and meanwhile, the spring 19 is prevented from being pressed. After the external force is eliminated (namely, the plate 21 is moved away), the spring 19 extends under the action of oil pressure and spring force, the piston 5 moves rightwards, the volume of a piston rod cavity is reduced, and oil flows into a cavity B of the cylinder body 18 through holes 7-phi 5, 4-phi 6 and 8-phi 16; meanwhile, the volume of the cavity A (the piston head cavity of the piston 5) of the cylinder body 18 is increased, the oil pressure is reduced, a pressure difference is formed, oil in the cavity B of the cylinder body 18 is sucked into the cavity A from the hole 7-phi 5, under the action of spring force, the piston 5 moves rightwards to stop moving when the surface D of the piston head contacts the left end surface of the cylinder opening 15, the material blocking block 1 returns to the initial position, and the whole buffer mechanism waits for the next working cycle.
The hydraulic buffer mechanism for the baffle realizes stable buffer braking in the process of conveying high-speed and heavy-load plates, and improves the positioning accuracy of material blocking. The progressive distribution of the throttling holes of the cylinder body and the decreasing of the aperture size are adopted to realize the buffering; the section of the cavity A18-1 without a hole is closed after the piston compresses oil to the section, and the space cannot be compressed continuously, so that brake positioning and spring compression and protection are realized; the service life and the recycling of the buffer mechanism are realized by adopting a built-in spring installation mode and a cylinder body double-cavity intercommunication structure. The whole device is simple in structure and convenient to install.
