[0020] The utility model will be described in further detail below in connection with the drawings and specific embodiment:

[0021] Referring to Figures 1-5 A closed press machine guide rail self -lubricating device, including frame 1 and sliding groove 2, and the sliding groove 2 is arranged in the both sides of frame 1 respectively, and the sliding body 4 on the punch press is slidably connected with the sliding groove 2 through the sliding block 3, so that the sliding body 4 can realize up-down linear motion in the sliding groove 2, and the sliding groove 2 is used to position and guide the kinematic pair in the mechanical equipment, thereby ensuring the accuracy and stability of the mechanical equipment.

[0022] As shown in the figure, a cavity 5 is arranged directly above the sliding groove 2, and a box 6 is arranged on the cavity 5, and the box 6 contains lubricating oil for lubricating the sliding groove 2. When the press is working, the lubricating oil in the box 6 will not leak out due to the large stamping force. A cover can be arranged on the top of the box 6 to supplement the lubricating oil in the box 6. The box 6 is partially arranged outside the cavity 5 and directly above the sliding groove 2. In order to enable the lubricating oil in the box 6 to lubricate the sliding groove, a through hole 7 is arranged at the bottom of the box 6, and a ball 8 is arranged on the through hole 7. The diameter of the ball 8 is larger than that of the through hole 7, so that the ball 8 can block the through hole 7 to prevent the lubricating oil from flowing out. The lower part of the ball 8 is located outside the through hole 7, and the leaked part of the ball is located outside the bottom plate of the box 6. The initial state of the ball 8 is located on the through hole 7, and the through hole 7 is blocked to prevent the lubricating oil in the box 6 from flowing out.

[0023] Specifically, a cotton pad 9 is arranged on the sliding block 3. The cotton pad 9 can be fixed on the sliding block 3 by glue or screws to prevent the cotton pad 9 from falling during work. The cotton pad 9 is a flexible contraction member. When the press stamping work is finished and the sliding body 4 is in the rising state, the surface of the cotton pad 9 on the sliding block 3 contacts the bottom of the box 6. The cotton pad 9 specifically contacts the lower half of the ball 8. When the cotton pad 9 contracts to the lowest position, the ball 8 is pushed upward, so that the bottom of the ball 8 is in the same plane as the bottom of the through hole 7 of the box 6. The lubricating oil in the box 6 flows out through the gap between the ball 8 and the through hole 7, flows down from the end of the sliding groove 2, and lubricates the sliding groove 2. When the press is working, the sliding body 4 is in the descending state, and the cotton pad 9 moves from the initial contact position to the position away from the bottom of the box 6. The cotton pad 9 expands to the initial state, and the ball 8 on the through hole 7 returns to the initial state, so that the lubricating oil in the box 6 cannot continue to flow out, and the guide rail self-lubrication of the press is realized.

[0024] In order to prevent the box 6 from falling during the work of the press, a plate 10 is arranged on the outside of the rack 1. A fixed shaft 11 is arranged on the plate 10. An adjustable block 12 is arranged on the fixed shaft 11 for adjusting the height. The fixed block 12 is fixed by two side positioning pins 13. A cylinder 14 is arranged on one side of the movable block 12. The cylinder 14 can convert pressure energy into mechanical energy to drive the mechanism to realize reciprocating linear motion. In order to prevent the cylinder 14 from moving, the cylinder 14 is fixed on the movable block 12. The output shaft 15 of the cylinder 14 is fixed on one side of the box 6 through the movable block 12. The end of the output shaft 15 of the cylinder 14 is generally provided with external threads. One side of the box 6 can be provided with internal threads matched with the external threads. The threads are connected with the box 6 through rotation. Through the work of the cylinder 14, the box 6 can be pushed out to the side of the cavity, which provides convenience for replacing the box 6 and adding lubricating oil. Workers can operate through the ladder to ensure that the lubricating oil is sufficient to lubricate the sliding groove 2.

[0025] In the embodiment, the box 6 is not a kind of, the box 6 that can be connected with the output shaft 15 of the cylinder 14 threaded rotation cooperation is all realized, part needs to be located above the chute 2, the through hole 7 of the bottom of the box 6 is also located above the chute 2.

[0026] Working principle: when the press stamping work is finished, the sliding body 4 is in the rising state, the cotton pad 9 on the sliding block 3 is in contact with the lower side of the ball 8, the ball 8 is pushed up, the lubricating oil in the box 6 flows out through the through hole 7, and the lubricating oil flows down from the end of the chute 2 to lubricate the chute 2; when the press is working, the sliding body 4 is in the falling state, the ball 8 on the through hole 7 returns to the initial state to block the through hole 7, so that the lubricating oil in the box 6 cannot continue to flow out, and the guide rail self-lubrication of the press is realized.

[0027] The above embodiment is only used to illustrate the technical scheme of the utility model, and is not limited thereto; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical scheme recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical scheme deviate from the spirit and scope of the technical scheme of the utility model.
