A connection socket for a tubular connection that includes: a socket cup having a metal alloy composition and a sealing portion, the sealing portion comprises a primary and a secondary sealing recess; a primary seal positioned within the primary sealing recess, the primary seal comprising an elastomeric material having a service temperature, and a secondary seal positioned within the secondary sealing recess, the secondary seal comprising a metal composition. Further, the secondary seal has a melting temperature at or above the service temperature of the primary seal.

A working head for a hydraulic power tool including a head frame and a first moveable die head configured to move along the working head frame. The first moveable die head configured to receive a first moveable die comprising a first body length. A second die head is adapted to receive a second die comprising a second body length. The first body length of the moveable die is different from the second body length of the stationary die.

A radial press is provided with a base structure, a pressing tool accommodated therein and a drive unit. The pressing tool comprises a number of base jaws which are arranged about a press axis and can be moved by the drive unit towards or away from the press axis in a synchronous manner and radially in relation to said press axis, and substantially wedge-shaped press-jaw heads can be exchangeably attached to the base jaws. A plurality of press-jaw head sets is stored in an associated magazine, the press-jaw head sets being for different press diameters. The press-jaw heads have two markings on at least one axial end side directly adjacent to both wedge surfaces. In addition, the two respective opposing markings of two neighboring press-jaw heads are aligned with one another. Markings that are different from one another are provided for different press-jaw head sets.

Embodiments disclosed herein describe systems and methods for coupling a cap with tubing utilizing a linear actuator configured to deform metal from a perforation gun tube into holes within the cap, wherein the deformed metal is configured to secure the tube and the cap.

A press tool for joining workpieces by forming, has at least two pressing jaws that can be moved relative to one another, with which pressing jaws the workpieces to be joined can be encompassed, at least partially, and which form a matrix for at least one of the workpieces to be joined, and has a closing point formed by mutually dedicated end faces of two of the pressing jaws. In an area adjacent to at least one of the end faces of the closing point, the surface of the associated pressing jaw may be retracted by an offset.

A method for joining members of the present invention is as follows: a second member is inserted through a hole part of a first member; a guide shaft is inserted through a through hole of rubber; the rubber with the guide shaft inserted is inserted into the second member; and a drive mechanism relatively moves pushers and toward each other to compress the rubber in the extending direction of the guide shaft so that the rubber is expanded outward from inside to expand and deform at least a portion of the second member inserted into the hole part, thereby joining the second member to the first member.

A pressing tool for plastically deforming a workpiece is described. The pressing tool includes a housing and an electric motor for actuating the pressing tool. The pressing tool also includes an instrument seat which is adapted to receive an interchangeable instrument head at the housing. The pressing tool also includes a mechanical safety element which is arranged in a manner that is movable from an open position, in which an instrument head may be inserted into the instrument seat, into a closed position, in which the instrument head is locked in the instrument seat. The pressing tool additionally includes a mechanical actuating element which may interact with the safety element in order to be able to cause the pressing tool to be enabled for a pressing process.

In present invention, there is disclosed a guardrail assembled by stamping including two rails, which are spaced from each other and disposed horizontally, and balusters, which are spaced from one another and disposed vertically. The rails are provided thereon with a plurality of spaced insertion holes. The insertion holes in the upper and lower adjacent rails are arranged in vertical alignment. The insertion holes in the rails are blind holes arranged to face inwards. The plurality of balusters are separately inserted into the vertically aligned insertion holes, allowing assembly and attachment of the plurality of balusters with and to the rails. Portions extending outwardly from walls of the insertion holes form abutment portions. After end portions of the balusters are inserted into the insertion holes, the end portions of the balusters are subjected to a stamping process so as to be bent outwardly to form rolled edge rims. The rolled edge rims abut against the abutment portion, achieving secure attachment of the balusters to the rails. The present invention provides the advantageous benefits of firm and secure assembly, convenient and fast assembly and good anti-corrosion performance.
