摘要： This invention is comprised of a lower die having a groove-like cavity formed at its upper surface; a rotary die supported in the cavity of the lower die at both ends thereof by a shaft and rotatably stored in it; an upper die arranged above the rotary die; and a driving device for rotating said rotary die in a downward direction after the upper die is opened and for retracting it. The cavity is formed with some protrusion steps at its inner circumferential surface for use in supporting the rotary die when pressed. The rotary die is formed with a forming part for gathering and bending a metallic plate at its upper surface to be extended in a longitudinal direction of the rotary die. The gathering and bending blade to be fitted to the forming part of the rotary die is formed at the upper die. In the case of the present invention, the aforesaid rotary die is supported at the protrusion steps when pressed while the outer edge of the forming part is being abutted against the upper edge of the lower die and after pressing operation, it is rotated in a downward direction by the driving device.

摘要： Since a conventional negative-angle press-forming swing die is rotationally supported on a support shaft extended parallel to the bottom surface of the body of a press-forming machine, parts of a parting line between a fixed support base and the support part of the swing die in different sections have different heights, respectively, when the swing die is used for forming an article having a curved shape curving in a wide height range. Therefore, even if the fixed support base can be designed for one of the sections, the fixed support base cannot be formed for other sections, and thus, it is difficult to form a fixed support base for forming such an article. Operations for uniting together a fixed support base 4 for fixedly supporting a workpiece W and a support die and for composing and decomposing a negative-angle press-forming die to take out a product processed by a negative-angle press-forming process are achieved by turning an L-shaped die, and a rotational support mechanism 21 serving as a pivot on which the L-shaped die is turned is inclined at an inclination determined according to the height range of a curved surface to be formed.
摘要翻译：由于传统的负角冲压成型摆动模具旋转地支撑在平行于压制成形机的主体底面延伸的支撑轴上，所以在固定支撑基座和支撑部分之间的分型线的部分当摆动模具用于形成在宽的高度范围内弯曲的弯曲形状的制品时，不同部分的摆动模具分别具有不同的高度。因此，即使固定支撑基座可以设计成一个部分，固定支撑基座也不能形成为其他部分，因此难以形成用于形成这种制品的固定支撑基座。将用于固定支撑工件W和支撑模的固定支撑基座4结合在一起并用于组合和分解负角压制成形模以取出通过负角压制成形工艺处理的产品的操作通过转动L形模，并且用作L形模的转动的枢轴的旋转支撑机构21以要形成的曲面的高度范围确定的倾斜倾斜。

摘要： The present invention provides a bending die in which the fixed die 1 and the rotary die 2 are surface contacted to each other, the rotary die 2 is rotated rearward after press forming to cause the workpiece 3 to be moved away from the die, wherein the contact surface 9 between the fixed die 1 and the rotary die 2 is formed in a flat surface. In addition, the present invention is set such that the rotary center point P of the rotary die 2 is set outside the line 10 drawn from one end C1 of the linear line indicating the contact surface 9 of the rotary die 2 in a direction of right angle in respect to the linear line when the contact surface 9 is seen in a section of a direction perpendicular to the axis of the rotary die 2. With such an arrangement as above, a machining of the contact surface 9 can be facilitated more and under a lower cost than those as compared with those forming the arcuate surface as found in the prior art.
