[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-3 As shown, a multi-point hydraulic cushion structure for a press includes a multi-point hydraulic cushion 1. The multi-point hydraulic cushion 1 has several guide holes 14 inside. A hydraulic cylinder piston rod 12 is vertically slidably connected inside the guide holes 14. An oil delivery mechanism is fixedly connected to the outside of the multi-point hydraulic cushion 1. The oil delivery mechanism is connected to multiple annular oil spray containers 9 through hoses 8. The annular oil spray container 9 is an annular hollow shell. Multiple high-pressure nozzles 13 are fixedly connected to the inner side wall of the annular hollow shell. An oil delivery station is set on the upper side of the multi-point hydraulic cushion 1 and around the guide holes 14. The annular oil spray container 9 can be detachably fixed at any one of the oil delivery stations.

[0024] In use, the annular oil spray container 9 is fixedly connected to the designated oil supply station, so that multiple annular oil spray containers 9 are located on the outside of multiple hydraulic cylinder piston rods 12. A hydraulic cylinder is fixedly connected to the lower side of the hydraulic cylinder piston rod 12. When the equipment completes the stretching of the tool, the hydraulic cylinder will drive the hydraulic cylinder piston rod 12 to move up and down between the guide hole 14 and the inside of the annular oil spray container 9. During this process, the lubricating oil transmitted to the inside of the annular oil spray container 9 through the oil supply mechanism will be sprayed onto the surface of the hydraulic cylinder piston rod 12 through the high-pressure nozzle 13. This can reduce the friction between the hydraulic cylinder piston rod 12 and the guide hole 14, reduce wear, extend service life, and at the same time ensure smoother movement of the hydraulic cylinder piston rod 12, increasing the stability of the equipment.

[0025] like Figure 1 As shown, the oil delivery mechanism includes two collection boxes 2, which are fixedly connected to both sides of the multi-point hydraulic cushion 1. The lower end of the collection box 2 is connected to an oil delivery pump 7 fixedly connected to the outside of the multi-point hydraulic cushion 1 through a delivery pipe 6. The oil delivery pump 7 is connected to a hose 8. When in use, the oil delivery pump 7 is started, and the lubricating oil inside the collection box 2 is delivered to the oil delivery pump 7 through the lower rotating connection delivery pipe 6. Then, the oil delivery pump 7 delivers the oil to the inside of the annular oil spray container 9 through the hose 8, thereby improving working efficiency.

[0026] As shown in 1-2, the upper side of the multi-point hydraulic pad 1 can be provided with a drainage structure, which includes a horizontal drainage groove 3 and a vertical drainage groove 4 opened on the upper side of the multi-point hydraulic pad 1, the horizontal drainage groove 3 and the guide hole 14 arranged in a row are communicated, one end of the horizontal drainage groove 3 and the upper end of the collection box 2 are communicated, the vertical drainage groove 4 and the guide hole 14 arranged in a column are communicated, and the end of the vertical drainage groove 4 and the horizontal drainage groove 3 are communicated; in use, when the high-pressure nozzle 13 sprays lubricating oil on the hydraulic cylinder piston rod 12, the lubricating oil inevitably scatters on the surface of the multi-point hydraulic pad 1; at this time, the residual lubricating oil on the surface of the multi-point hydraulic pad 1 is quickly guided into the horizontal drainage groove 3 through the vertical drainage groove 4, and then transmitted to the inside of the collection box 2 through the horizontal drainage groove 3, thereby reducing the waste of lubricating oil and the pollution to the environment, and improving the utilization rate of resources.

[0027] As shown in Figure 2 , the middle position of the inside of the collection box 2 is provided with a detachable sponge body 5; in use, the sponge body 5 can effectively filter the impurities such as dust, rust and particles contained in the lubricating oil in the collection box 2, so as to reduce the impurities into the oil pump 7, the annular oil spraying container 9, the high-pressure nozzle 13 and other components, thereby protecting the normal operation of the whole system and reducing the damage to the equipment in the use process.

[0028] As shown in Figures 3-5 , the material of the oil conveying station is iron, and the lower side of the annular oil spraying container 9 is fixedly connected with a magnet 10; in use, the adsorption force of the magnet 10 can quickly connect the annular oil spraying container 9 with the oil conveying station, so that the connection or separation can be realized, the operation difficulty and labor intensity are reduced, the time is greatly saved, and the work efficiency is improved.

[0029] As shown in Figure 2 , the height of the inner wall of the lower side of the horizontal drainage groove 3 gradually decreases from the middle position to both ends; in use, when the lubricating oil flows into the inside of the horizontal drainage groove 3, due to the height difference of the two sides of the horizontal drainage groove 3, the lubricating oil will naturally flow from the middle position to both ends under the action of gravity; this natural drainage mode does not need additional power equipment, saves energy, and also reduces the complexity and cost of the system.

[0030] The working principle of the utility model is as follows: in use, the annular oil spraying container 9 is fixedly connected on the specified oil conveying station, the lower side of the hydraulic cylinder piston rod 12 is fixedly connected with a hydraulic cylinder, when the device completes the stretching of the appliance, the working of the hydraulic cylinder will drive the hydraulic cylinder piston rod 12 to move up and down in the guide hole 14 and the inside of the annular oil spraying container 9; in this process, the lubricating oil transmitted to the inside of the annular oil spraying container 9 by the oil conveying machine will be sprayed on the surface of the hydraulic cylinder piston rod 12 through the high-pressure nozzle 13;

[0031] In conclusion, the technical scheme adds the annular oil injection container 9 matched with the hydraulic cylinder piston rod 12, which can simply and uniformly spray lubricating oil on the surface of the hydraulic cylinder piston rod 12 during the up and down movement of the hydraulic cylinder piston rod 12, thereby reducing the friction between the hydraulic cylinder piston rod 12 and the guide hole 14, reducing the wear, prolonging the service life, and ensuring the movement of the hydraulic cylinder piston rod 12 more smooth, increasing the stability of the equipment.

[0032] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered within the scope of protection of the present application. The structures, devices and operation methods not specifically described and explained in the present application are implemented according to the conventional means in the art, unless otherwise specified and limited.
