    • A rotary forming apparatus (10) having a pair of lower and upper die carrier units (14, 16), each of which is rotatable on opposite sides of a workpiece (W), and having a plurality of die supports (22, 24) swingably mounted on each of the die carriers, and supporting upper and lower dies (82, 80), and having die support guide roller pairs (66, 68) mounted together on a common axis side by side on each the die supports and located adjacent to the leading or trailing edge of the respective die support, and a guide plate (56) alongside one end of each die carrier, and, guide grooves (58, 60, 62, 64) formed in each guide plate for receiving the pairs of die support guide rollers (66, 68), the grooves being formed so as to define inner and outer guide surfaces (74, 76), with one of the die guide rollers engaging one of the inner and outer surfaces and the other of the die guide rollers engaging the other of the inner and outer guide surfaces. Also disclosed is a method of rotary forming using such apparatus.
    • 一种旋转成形装置(10),具有一对下模托架单元和上模托架单元(14,16),每一个可在工件(W)的相对侧上旋转,并具有多个模具支座(22,24) 可摆动地安装在每个模具托架上,并且支撑上模具和下模具(82,80),并且具有模具支撑引导辊对(66,68),其在共同的轴上并排地安装在每个模具支撑件上并且位于相邻 相应的模具支撑件的前缘或后缘以及沿着每个模具载体的一端的引导板(56),以及形成在每个导板中的导向槽(58,60,62,64),用于接收 模具支撑引导辊(66,68),所述槽形成为限定内部和外部引导表面(74,76),其中一个模具引导辊接合模具的内外表面和另一个模具 导向辊接合内导向表面和外引导表面中的另一个。 还公开了使用这种装置的旋转成形的方法。

    • Guillotine shearing machine, especially for cutting continuous metal bands (90), in which each of the two longitudinal blades (15), (16) counterpoised by means of connections to connecting rods (39), (40), (41), (42) each supported by a pair of cranks (31-32), (35-36) and (33-34), (37-38), translates, both parallel to each other, on equal circular trajectories in such a way that one blade (15) encountering the other (16) in proximity to the cutting plane and progressively superimposing each other, effects the cut, speed of the blades (15), (16) in each cycle being regulated according to the sliding speed of the band (90) so that in the zone of contact the speed of the blades (15), (16) coincides with that of the band (90) enabling pieces of band to be cut off in whatever length is desired.
    • 尤其是用于切割连续金属带(90)的断头台剪切机,其中两个纵向叶片(15),(16)中的每一个通过连接到连杆(39),(40),(41),( (31-32),(35-36)和(33-34),(37-38)支撑的每个曲柄(42)在相同的圆形轨迹上彼此平行地平移,使得 在切割平面附近遇到另一个(16)的一个叶片(15)并且逐渐叠加,从而使每个循环中的叶片(15),(16)的切割速度根据滑动速度进行调节 (90),使得在接触区域中,叶片(15),(16)的速度与带(90)的速度重合,使得条带能够以任何长度被切断。
