摘要： A clamping apparatus (3) for holding a workpiece (W) between an upper punching tool (19) and a lower punching tool (21) in a machine (1). A frame (33) attaches the clamping apparatus (3) to the machine (1). The clamping apparatus (3) comprises an upper clamp (61) and a lower clamp (57), the latter pivotably cooperating with the upper clamp (61) in order to secure the workpiece (W). The clamping apparatus (3) also comprises a plate member (51) and rods (49) and (75). These rods (49) and (75) are mounted in the frame (33) in a direction perpendicular to the workpiece (W). The lower end of the rods (49) and (75) are attached to the lower clamp (57) and the upper end of the rods (49) and (75) are attached to the plate member (51). A spring (83) is arranged between the lower clamp (57) and the plate member (51) for the purpose of maintaining the lower clamp (57) and the plate member (51) in horizontal orientation whenever the lower clamp (57) collides with the lower punching tool (21).

摘要： This disclosure relates to an indexing feed mechanism for a cutting machine comprising an indexing vise for gripping a workpiece and moving it forward into a cutting position. The mechanism includes a lead screw interengaged with complementary means formed on a stopper means adapted to limit the rearward extent of the stroke of the indexing vise. Rotation of said screw will, therefore, cause translation of said stopper means thereby varying the rearward limit of travel of the indexing vise during its stroke. The lead screw extends from a rotatable shaft and means located at the operating station of the cutting machine are provided for rotating the shaft. The shaft is operably connected to a digital indicator which indicates in digital numerals the predetermined stroke of the indexing vise as a function of the angular position of the shaft.
摘要翻译：本公开涉及一种用于切割机的分度进给机构，其包括用于夹持工件并将其向前移动到切割位置的分度台钳。该机构包括与形成在适于限制分度台钳的行程的向后范围的止动装置上的互补装置相互接合的导螺杆。因此，所述螺杆的旋转将导致所述止动装置的平移，从而改变分度台钳在其行程期间的行进的向后极限。导螺杆从可旋转的轴延伸，设置在切割机的操作台上的装置用于旋转轴。轴可操作地连接到数字指示器，数字指示器以数字数字表示作为轴的角位置的函数的分度台钳的预定行程。
