Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in fig. 1 in combination with fig. 2 to 6, the upward bending die structure with the shear band comprises an upper die holder 1, a lower die holder 2, an upper forming male 3, an upper positioning block 4, a shearing punch 5, a lower floating block 6, a lower forming male 7 and a nitrogen spring 8, wherein the upper positioning block 4 is fixed on two parts of the lower end face of the upper die holder 1, the upper forming male 3 is sleeved on the upper positioning block 4, the nitrogen spring 8 is fixed on two side parts of the upper end of the lower die holder 2, the lower forming male 7 is fixed on the middle position of the upper part of the lower die holder 2, the shearing punch 5 is fixed on the middle position of the lower part of the lower die holder 2 and is located between the two upper forming male 3, and the lower floating block 6 is fixed between the nitrogen spring 8 and the upper forming male 3.

Further, the nitrogen spring 8 comprises a nitrogen cylinder 9 and a fixed sleeve 10, and the nitrogen cylinder 9 is fixed in the fixed sleeve 10.

Further, a guide post is arranged in the upper molding male 3.
