A punch assembly with interchangeable tips includes a punch body and a punch tip releasably coupled to the punch body. The punch body includes a proximal end, a distal end opposite the proximal end, and a cross-sectional shape defined between the proximal end and the distal end. The proximal end includes a flange configured to engage a punch holder. The distal end includes a distal surface include a front side and a rear side. At least one first magnet faces a same direction as the front side and at least one second magnet faces a same direction as the rear side. The punch tip is coupled to the distal end of the punch body via a magnetic coupling provided by the at least one first magnet and the at least one second magnet.

A metal plate includes: a recessed portion provided at one end surface by cutting out the metal plate in a planar direction of the metal plate, the recessed portion having an engaging portion inside the recessed portion; and a protruding portion provided at a position on another end surface, the position corresponding to that of the recessed portion, the protruding portion protruding in the planar direction, the protruding portion being engaged with the engaging portion by applying a bending process such that the engaging portion is hooked by the protruding portion, wherein a length from a proximal end portion to a distal end portion of the protruding portion before the bending process is applied is equal to or less than a depth of the recessed portion at a position of the recessed portion, the position facing an end surface of the proximal end portion of the protruding portion.

A rotary press die has a rotating die forming a negative angle part on a plate-like work and a fixed die arranged outside the rotating die and forming a molding part except for the negative angle part on the work. The rotating die is a press molding die which is formed such that the press molding die rotates about a rotating axis when the work is removed and can be retracted inside the fixed die. A rotating block is configured by a fixed piece arranged on the fixing table and having a concave slide surface having the rotating axis as a center. A moving piece is arranged on the rotating die and having a convex slide surface which can slide on the concave slide surface by using the rotating axis as a center. An opening angle between the concave slide surface and the convex slide surface is 80° to 100°.

A modular guided keeper base, guided keeper assembly, and related method includes a modular guided keeper base that mounts to a die member. The guided keeper base has an integrated stop for guide pin retention. The guided keeper base can also accommodate a variety of bushings within the base. The guided keeper base is attached to a die member using a mounting flange(s). Mounting fasteners pass through the fastener holes in the mounting flanges and are anchored in the die member to securely retain the guided keeper assembly in place. A retainer ring is mounted in an associated groove in the base over the heads of the mounting fasteners to prevent unintentional unfastening of the fasteners from the die member.

A torsion shaft structure based multi-link all-electric servo synchronous bending machine, comprising a machine frame, a lower die fixedly connected to the machine frame and used for bending, a slider capable of moving up and down along the machine frame, and an upper die fixedly connected to the slider and cooperating with the lower die to perform bending, wherein the slider is left-right symmetrically connected to drive mechanisms for driving the slider to realize a transmission ratio adjustable motion.

A multi-directional multi-cam press device may include a cam base fixed to the lower mold, a first cam slide provided to slide forwards and backwards along a first direction of the cam base, at least a first punch unit provided in the first cam slide along a first direction, a cam drive fixed to an upper mold configured of moving in a vertical direction with respect to the lower mold, and making cam contact with the first cam slide, a second cam slide provided in the cam drive to move forwards and backwards in a second direction perpendicular to the first direction and in contact with the cam base side, and at least a second punch unit provided on the second cam slide along a second direction.

A positioning guide device for positioning a blank in a forming die. The positioning guide device includes a positioning guide having a sloped positioning face designed to allow a peripheral edge of the blank to be positioned in a transverse direction by contact with the positioning face. The positioning guide device further comprises a housing module, the positioning guide being mounted in the housing module so as to be linearly displaceable in the transverse direction. The housing module having a spring system for preloading the positioning guide in the transverse direction.

Techniques for implementing and/or deploying a swage machine, which includes a die plate that enables a die to be used to conformally deform a pipe fitting around pipe segment tubing to be loaded in the swage machine, a grab plate having grab plate sections that are pivotably connected, and grab adapter sections. Each grab adapter sections includes a base sub-section connected to a corresponding grab plate section, in which an inner surface of the base sub-section includes an alignment notch, and a modular sub-section to be secured to the base sub-section, in which an outer surface of the modular sub-section includes an alignment tab to be disposed within the alignment notch in the base sub-section and an inner surface of the modular sub-section includes a grab tab section that matingly interlocks with a fitting grab notch on the pipe fitting to facilitate securing the swage machine to the pipe fitting.
