Detailed Description
Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.
In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
In the present utility model, 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; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
The utility model discloses a hollow shaft forming die with a material beating function, which comprises an upper die and a lower die, wherein the upper die comprises an upper die plate 1, an upper die sleeve 2, a punch sleeve 3, a punch 4, a material beating block 5, a material beating core rod 6 and a material beating rod 7. The upper die sleeve 2 is sleeved on the outer side of the punch sleeve 3, the upper die sleeve 2 is fixed on the upper die plate 1, the punch sleeve 3 is sleeved on the outer side of the punch 4, a clamping groove is formed in the bottom of an inner cavity of the punch sleeve 3 and is clamped with a boss at the bottom of the punch 4, and the punch sleeve 3 is fixed with the punch 4.
The punch 4 is provided with a section of chute 41, a punching block 5 is arranged in the chute 41, the punching block 5 can move back and forth in the chute 41, and the width of the punching block 5 is larger than the diameter of the punch 4.
