摘要： Adjustable length punch assemblies are disclosed. An adjustable length punch assembly in accordance with present invention may be used with a punch press including a tool holder adapted to receive punch assembly and a ram adapted to move longitudinally along a ram axis. An adjustable length punch assembly in accordance with present invention preferably includes a punch body assembly disposed in threading engagement with a drive body assembly having a surface adapted to be struck by ram of punch press. The length of punch assembly may be adjusted by rotating of one body relative to other body. The adjustable length punch assembly preferably includes a lock mechanism for selectively preventing rotation of the punch body assembly relative to the drive body assembly. The lock mechanism preferably comprises a lock shaft coupled to one of bodies and a lock key slidingly coupled to other of bodies such that lock key slides along a lock key path. The lock key path is preferably disposed at an angle relative to ram axis when punch assembly is received by tool holder.

摘要： A press brake tool holder having a horizontally elongated body having a support plate, and a horizontally elongated clamp having upper and lower portions and pivotally attached to the body between the upper and lower portions so as to capture between it and the support plate the upwardly extending shank of a brake press tool. A handle-operated cam shaft is carried by the body and is linked to the upper portion of the clamp by cam follower elements which provide a rigid linkage. Clamps may be thus mounted to both sides of the body, and each can be independently operated when the other is removed. The clamp is mounted to the body by means of mounting pins having articulating heads that are slidingly received in slots in the body, the slots having enlarged entryways enabling the clamp to be removed from or attached to the body by sliding the clamp with respect to the body to align the articulating heads with the slot entryways.

摘要： An adjustable die holder for a press brake comprising an elongated base block adapted to be attached to a jaw of a press brake and having a first bore formed therein and a horizontal upper surface; a top plate slidable on the upper surface of the base block. The top plate bears a die holding element and having a second bore formed through it, the second bore being in substantial alignment with the first bore. A die carried by the die holding element has a working surface oriented away from the die holding element. Extending through the first and second bores is an elongated threaded member having external threads. A handle is provided for rotating the threaded member with respect to an internally threaded element which threadingly mates with the elongated threaded member, the handle having an unlocked position wherein the top plate is free to slide upon the upper surface of the base block and a locked position wherein the top plate is locked to the base block.

摘要： An adjustable gage block for a press brake comprises a base attachable to the press brake and a body pivotally carried by the base for pivoting movement about a vertical axis. The body carries a first guide member, and a second guide member is pivotally carried by the body for pivoting movement about said vertical axis with respect to the first guide member. One or both of the guide members have upwardly-facing guide surfaces laying in a horizontal plane to support a workpiece, and each guide member has a vertical guide surface, with the vertical guide surfaces laying in convergent planes. Adjustment means are provided for adjusting the angle between the vertical guide surfaces of the guide members to accommodate the shape of a workpiece. Desirably, a workpiece support is mounted to the press brake spaced from the gage block, the workpiece support having an edge guide surface positioned to engage an edge of the workpiece and to orient the workpiece with respect to the gage block.
