Power swage tool
11623265 · 2023-04-11 · ·

A swage tool includes a power unit connected to a yoke. The power unit exerts vertical force on a die block. The yoke holds swage dies in place and opposes the force exerted by the die block. The die block transfers the load exerted by the power unit into the swage dies, which surround the connector. The swage dies convert vertical force from the power unit into a radial swage on the connector. Quick release endplates hold the swage dies in place in the yoke and the die block. A yoke shroud keeps broken pieces of the yoke together if the yoke fails. A counter records the number of swages made by the tool. A rotating handle, a stand, remote wireless actuation and swage die identification imprints are also provided.

METHOD FOR MACHINING OUTER CIRCUMFERENCE OF METAL END CROSS-SECTION AND METHOD FOR JOINING METAL COMPONENT OBTAINED BY THE MACHINING METHOD WITH ANOTHER MEMBER
20170368588 · 2017-12-28 · ·

Provided are a method of for machining the outer circumference of a metal end cross-section, the method being capable of easily forming at least any of a deep groove, a deep recess, and a flange which are smooth and uniform in the longitudinal direction of a metal rod or metal pipe in the periphery of the cross-section of any of the end part of the metal rod or metal pipe, the drawn end part of the metal rod or metal pipe, and the hub hole forming part of the metal pipe; and a method for joining a metal component obtained by the machining method with another member. The machining method of the present invention is characterized in that: splitting is advanced by successively repeating press forming operation multiple times by using a slitting punch, in which a tip part has a sharp cutting edge, and the cutting edge is formed so as to have a shape equal to or partly equal to the outer shape of the cross section of a metal end part and so as to have a diameter smaller than the outer diameter of the cross section of the splitting object; and in order to control the depth of metal cracking cleft created with each press forming operation, a pressing die for pinching the outside of a metal rod or at least a pressing die of one side of pressing dies for pinching the inside and the outside of a metal pipe is disposed while its position is moved according to the distance of a split portion.

20230182371 · 2023-06-15 ·

A parison tube former utilizes a radial compression heater to heat a very specific portion of a preform tube for stretching. The heater has a plurality of compression dies that form a central cavity for receiving the preform tube. The working surfaces of the compression dies close down onto the outer surface of the preform tube to heat the tube via conduction, which more accurately and precisely heats the preform tube. A first stretched portion of the preform tube is produced by stretching the preform tube after heating. A second portion of the preform tube is then located within the central cavity and is also heated by the radial compression heater and stretched to produce a second stretched portion of the preform tube and an unexpanded portion of the preform tube, or balloon portion of the parison tube.
