This coupling device for a tubular member is provided with: a base stand for holding an inner member and an outer member in a state in which the outer member is disposed around the inner member; a plurality of pressing members that are supported by the base stand in a movable manner in the radial direction of the inner member and the outer member and have a protruding part on the tip thereof; a pressing member that make contact with the final end of the pressing member and that can press the pressing member radially inward; and a drive mechanism that drives any one among the base stand and the pressing member in a direction perpendicular to the movement direction of the pressing member so that the one member moves relative to the other. The inner member and the outer member are caulked and coupled by driving, by the drive mechanism, any one among the base stand and the pressing member and displacing the pressing member radially inward to thereby expand, radially inward, a portion of a peripheral wall of the outer member by the protruding part.

A power tool including a moveable piston, a motor capable of driving the moveable piston to perform work on a work piece, and a distance sensor configured to sense a movement of the moveable piston. The distance sensor operable to provide sensor information indicative of the movement of the piston. A controller receives the sensor information from the distance sensor. The controller operates the motor to perform work on the work piece based in part on the sensor information that the controller receives from the distance sensor.

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 press tool for crimping a cylindrical fitting includes first and second jaws, each of which is pivotable about a pivot axis between an open position and a closed position. The press tool also includes an indicium coupled to at least one of the first jaw, the second jaw, or another component of the press tool illustrating a preferred orientation of the cylindrical fitting when positioned between the first and second jaws prior to initiating a crimping operation.

A crimp tool is disclosed that creates a plurality of impressions on a connector to secure metal to the connector using a single compression of the connector. The crimp tool includes a plurality of die. Each die including a plurality of impression teeth used to create the plurality of impressions on the connector.

An automotive pipe mounted on an automobile includes an inner pipe portion through which a fluid passes, an outer pipe portion surrounding a part of the inner pipe portion, and a restricting portion restricting the outer pipe portion from moving in an axial direction thereof, and at least an outer circumferential surface of the inner pipe portion facing the outer pipe portion is made of a resin.

The invention relates to a method and a coating device for applying a cladding layer onto the inner side of a carrier layer during the production of a multilayer heavy-duty pipe, with a pressure-exerting unit having a force application unit. A stable application of the cladding layer is achieved by having the coating device comprise a rolling tool with the pressure-exerting unit and the force application unit, and by providing the pressure-exerting unit with at least one pressure roller having a diameter that is smaller than the inside diameter of the heavy-duty pipe to be produced, and with at least one support element acting diametrically counter thereto with a supporting force in the operating state.

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.

An apparatus and method for crimping coupling rings are provided. The apparatus generally has a lower clamp head and an upper clamp head that may be drawn together by a fastener. The lower and upper clamp heads are designed to receive a first portion and a second portion of a coupling ring, respectively. A first and second post holds the clamp heads adjacent to each other. The upper clamp head is secured to the first post such that the upper clamp head may rotate in a generally circular motion to switch the apparatus from a closed to an open configuration, or vice versa. When the apparatus is placed in a closed configuration, the fastener may be engaged to draw the clamp heads together to increase the compressive force imposed on a coupling ring until the coupling ring becomes crimped.

Die sets for crimping busses to electrical connectors are provided. The die set includes a pair of dies where one die has a guide member for aligning the dies with the electrical connector, and the other die has a one or more indentors for impacting the electrical connector. The electrical connectors include a guide hole that receives the guide member.
