Crimping tool
11577299 · 2023-02-14 · ·

A crimping tool is described comprising a first crimping member, a second crimping member, at least one intermediate crimping member, a first sliding member and a second sliding member. The free ends of the first crimping member and the second crimping member form an opening of the crimping tool. The first crimping member, the at least one intermediate crimping member, and the second crimping member are sequentially hinged together via connecting devices. The first sliding member is slidably disposed on the free end of the first crimping member. The second sliding member is slidably disposed on the free end of the second crimping member. The first sliding member is adjacent to the second sliding member. The inner sides of the first crimping member, the at least one intermediate crimping member, the second crimping member, the first sliding member, and the second sliding member are formed to be pressed with the workpiece to be crimped. The crimping tool has a simple structure and good crimping performance, so that the workpiece is uniformly stressed and burrs on the workpiece can be reduced.

Device to install shoelace aglets
11548053 · 2023-01-10 ·

A kit for installing a replacement aglet on a shoelace includes a cutting tool configured to cut a damaged distal tip section from the shoelace. A replacement aglet is positioned on the trimmed free end of the shoelace following the cutting operation. The replacement aglet has a split-sleeve construction including a longitudinal slit that extends fully from end to end. The slit makes it easy to locate the replacement aglet on the trimmed tip section of the shoelace. A heat applicator applies heat to the aglet-bearing shoelace and causes the aglet to compressively shrink in the manner of a shrink wrap process. The aglet functions as an article of shrink wrap tubing. The heating process fuses together the lengthwise edges of the slit and thereby closes the slit.

Compact hose assembly device
11590552 · 2023-02-28 ·

A compact hose assembly device may include a housing defining a cavity and a hingedly attached door to enclose the cavity. Within the cavity, the compact hose assembly device may include at least one sliding drawer or similar storage device. The compact hose assembly device may include an air-over-hydraulic crimping machine on a sliding drawing or substrate, the air-over-hydraulic being in operable communication with an air compressor, hydraulic foot pedal pump, and the like for operation. The compact hose assembly device may be constructed and arranged for convenient, low downtime, on-site hose repair or assembly.

PORTABLE IN-LINE DIELESS CRIMPING TOOL
20230238760 · 2023-07-27 ·

An in-line portable, handheld hydraulic scissor-type action crimping tool having a handle assembly and a working head assembly is provided. The handle assembly has a tool frame portion and a neck portion. The working head assembly has a pair of jaw members joined so that they are movable relative to each other and held in place by a locking pin. One jaw member has a nest secured to or directly formed into the jaw member. The other jaw member has an indentor secured to or directly formed into the jaw member.

RADIAL PRESS
20230234314 · 2023-07-27 ·

A radial press is provided including a base, a hollow ring die mounted on the base rotatably relative to a press axis with an inner contour tapering in the direction of the axis and rotationally symmetrical, and a rolling element unit rotatable relative to the axis and having a pressure ring, which surrounds the axis, and a plurality of rolling elements arranged around the axis which are rotationally symmetrical. The rolling elements are supported on the pressure ring at a variable distance from the axis and can roll on the inner contour of the ring die. A rotary drive acts on the ring die or the rolling element unit and effects rotation about the axis. A feed drive also acts on the rolling element unit or the ring die and effects axial displacement of the rolling element unit and the ring die relative to each other.

Tubular joint roll forming machine

A joint module for forming a joint section from a tube that is formed at an operational speed by a roll forming machine may include a carriage positioned proximate the back end of the roll forming machine and configured to move in a longitudinal direction relative to the back end. A pleat die assembly may be mounted on the carriage and configured to repeatedly engage the tube to form a series of pleats thereby bending the tube to form the joint section, and a crimp die assembly may be mounted on the carriage and configured to engage the tube to crimp an end of the joint section and to sever the end of the joint section from the tube. The carriage may move relative to the frame while the tube is engaged with at least one of the crimp die assembly and the pleat die assembly.
