The invention provides a self-oiling stamping die guide assembly which comprises an upper die 1 and a lower die 2 with mutually matched contact surfaces. The device also comprises an oil feeding device 3, and a stop block 11 is fixedly arranged on the side wall of the upper die 1. The guiding sliding surface of the lower die 2 is provided with an oil outlet groove 21, a dispersing oil groove 22 and a lubricating oil groove 23 which are communicated sequentially from top to bottom. The oil feeding device 3 is arranged on the same side as the stop block 11, is fixedly arranged on the side wall of the lower die 2, and is respectively connected and communicated with the oil outlet groove 21 and an oil tank for storing oil through pipelines; the stopper 11 can drive the oil feeding device 3 to convey oil from the oil tank to the oil outlet groove 21 during the movement of the upper die 1 and the lower die 2, so that the oil flows through the dispersion oil groove 22 and the lubrication oil groove 23, and self-lubricating is realized.
In particular, as shown in fig. 1 and 2, fig. 1 is a schematic perspective view of the present invention. FIG. 2 is a schematic perspective view of the lower die and the oil feeding device of the present invention.
The guide sliding surface may have a wedge structure, that is, a structure in which an upper inclined surface and a lower vertical surface are combined. The oil outlet groove 21 is located on the upper inclined surface, and the lubrication groove 23 is located on the lower vertical surface. The upper end of the dispersion oil groove 22 is communicated with the oil outlet groove 21, and the lower end is communicated with the lubrication oil groove 23. The oil in the oil outlet groove 21 can flow from the oil outlet groove 21 to the lubricating oil groove 23 through the dispersion oil groove 22 under the action of gravity, and plays a role in lubricating the guide sliding surface. Meanwhile, in the process of moving the upper die 1 from top to bottom, the upper die is contacted with the guiding sliding surface of the lower die 2, so that oil in the oil outlet groove 21 can be slid to the position of the lubricating oil groove 23, and a lubricating effect is achieved.
In order to increase the lubrication area, the oil discharge groove 21 may be horizontally disposed. An oil inlet passage (not shown) may be formed in the lower die 2 at a position corresponding to the oil outlet groove 21, and an oil outlet of the oil feeding device 3 is connected and communicated with the oil inlet passage through a pipeline. The oil inlet passage may communicate with the oil discharge groove 21 through the oil injection hole 211. In order to ensure uniformity of oil discharge, the oil filling holes 211 may be provided in plurality and uniformly disposed on the oil discharge groove 21. In order to facilitate the dispersion of the oil on the guide sliding surface, oil filling holes 211 are provided corresponding to the upper ends of the dispersion oil grooves 22.

The invention is provided with the oil outlet groove 21, the dispersing oil groove 22, the lubricating oil groove 23, the stop block 11 and the oil feeding device 3. The stopper 11 conveys the oil to the oil discharge groove 21 by driving the oil feeding device 3 during the movement of the upper die 1 and the lower die 2, so that the oil is dispersed into the oil groove 23 through the dispersing oil groove 22. Because the dispersing oil groove 22 and the lubricating oil groove 23 are formed in the guiding sliding surface, after the dispersing oil groove 22 and the lubricating oil groove 23 are filled with oil, the lubricating effect can be achieved in the moving process of the upper die 1 and the lower die 2, and the lubricating area is increased, so that the guiding sliding surface is automatically lubricated in the moving process of the upper die 1 and the lower die 2.

In the present invention, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
In the present invention, unless expressly stated or limited otherwise, a first feature "up" or "down" a second feature may be the first and second features in direct contact, or the first and second features in indirect contact via an intervening medium. Moreover, a first feature being "above," "over" and "on" a second feature may be a first feature being directly above or obliquely above the second feature, or simply indicating that the first feature is level higher than the second feature. The first feature being "under", "below" and "beneath" the second feature may be the first feature being directly under or obliquely below the second feature, or simply indicating that the first feature is less level than the second feature.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
