摘要： A rotary punching machine comprises a pair of punching tools, namely a rotary punching tool with punches arranged on its circumference and a rotary counter tool, which co-operates with the latter, with dies in the form of punching bushings arranged on its circumference. The punching tool (1) and/or the counter tool (3) have a radial groove (12) on their circumferential surface between the individual punches (2) and/or the individual punching bushings (4), the depth of the groove being greater than the depth of penetration of the punches (2) into the punching bushings (4).

摘要： A multitool punch holder (12) having a head member (26) coupled to a punch press ram (16) as the press upper turret plate (22) rotates to bring the punch holder (12) into alignment with the ram (16). The punch holder (12) includes a rotary tool carrier (56) carrying a series of punches (80), each able to be selectively rotated into alignment beneath a striker rod (100) slidably mounted in a non rotating body member (30). Stroking of the ram (16) causes an engagement feature (108) to engage the striker rod (100) when the head member (26) telescopes into the body member (30) after axial movement of the holder (12) is arrested by contact with the workpiece (120). The striker rod (100) is then driven to force the coupled individual punch (80) into the workpiece (120). The striker rod (100) is urged to a raised position by an encircling stripper spring (110). A separation spring (42) urges the ram (16) and body member (30) to retracted position with the striker rod (100) out of engagement with the ram engagement feature (108). A detachable striker plate (88) of urethane provides non-marring contact with the workpiece (120).
摘要翻译：当压力机上转盘板（22）旋转以使冲头保持器（12）与冲头（16）对准时，多头冲头保持器（12）具有连接到冲压机冲头（16）的头部构件（26）。冲头架（12）包括承载一系列冲头（80）的旋转刀架（56），每个冲头能够选择性地旋转成在可滑动地安装在非旋转本体构件（30）中的撞杆（100）下方对齐。当保持器（12）的轴向移动通过接触而被阻止之后，当头部构件（26）伸缩到主体构件（30）中时，冲头（16）引起接合特征（108）接合撞击杆与工件（120）。撞针杆（100）然后被驱动以迫使联接的单个冲头（80）进入工件（120）。撞针杆（100）被环绕的剥离弹簧（110）推动到升起位置。分离弹簧（42）在冲击杆（100）脱离与冲头接合结构（108）接合的情况下将冲头（16）和主体构件（30）推动到缩回位置。聚氨酯的可拆卸撞板（88）提供与工件（120）的非损伤接触。

摘要： A region occupied by the work holder (20) in a mechanical coordinate system is memorized in a work holder region memorizing means (4). The sizes of a plurality of tool posts on a turret (24), or the sizes of tools to be inserted in these tool posts are memorized in a tool post shape memorizing means (4). A punching prohibition region-determining means (1) is adapted to determine a region, in which a punching operation of a tool is prohibited, on the basis of the contents of the work holder region memorizing means (4) and tool post shape memorizing means (4) when a tool is selected. A collision-preventing means (1) is adapted to ascertain just before a punching order has been put into practice that the position of a tool is within a punching prohibition region, and to stop the operation of the machine when the position of the tool is within the punching prohibition region.

摘要： A machine for punching holes (21) in sheet metal (10) has a punch roller (3) carrying a plurality of punches (4) and a back up roller (6) having a groove therein which has a bottom (14) at a predetermined depth in the back up roller (6). Its method of use is to run sheet metal (10) through the nip between the two rollers (3) and (6) so that the punches (4) punch out slugs (12) of metal so that a point (13) on each slug (12) bears against the bottom (14) of the groove which acts as a pivot point (13) on which the slug (12) pivots to cause the slug (12) to be completely freed from the parent metal (10) by the further action of the punch (4).

摘要： A die-pressing die used for die-pressing a workpiece includes a die body on whose upper face a die hole is formed and on whose bottom face a discharge hole for discharging dusts of the workpiece is formed, and a roller unit disposed within the die hole and having a roller protruding upward from the upper face of the die body. A collection passage for collecting the dusts is formed at a peripheral edge portion of the die hole. One end of the collection passage is opened at the upper face of the die body, and another end thereof is opened to the discharge hole. The collection passage is configured to suction air due to a negative pressure state in the discharge hole.

摘要： Provided are a die-pressing punch, a die-pressing die set and a beveling method each of which can improve operational efficiency of die-pressing such as beveling by adjusting an initial load of a coil spring according to a material of a workpiece. A punch body 25 is provided inside a punch guide 17 vertically movably, and a punch head 33 is provided at an upper end of the punch body 25 by being screw-fitted therewith. A coil spring 49 is disposed, inside the punch guide 17, between the punch body 25 and an upper free ball bearing 41. A ring-shaped joint member 51 is provided on a side of an outer circumferential surface of the punch body 25 and on an upper side of the punch guide 17, and the joint member 51 is jointed with the punch head 33 non-rotatably about an axial center C with respect to the punch guide and non-removably therefrom. An operable member 63 switches the joint member 51 between the rotatable state and the non-rotatable state, about the axial center C with respect to the punch guide 17.
