    摘要： The invention relates to an apparatus (1) for producing a peripheral groove (101) in an end portion (103) of a metal tube (100), in particular a metal tube (100) which is to be coated on the inside, the groove (101) being set up for receiving tube connectors, having a first, rotationally driven roller (3), a second, freely rotating roller (5), the first roller (3) having a roughened or structured surface (6) relative to the second roller (5), a pressing device (15) for producing a relative movement between the first and second roller (3, 5), between a first and a second position, the rollers (3, 5) assuming a first spacing from one another in the first position, which first spacing permits an introduction of a wall of the tube between the rollers (3, 5), and assuming a smaller, second spacing from one another in the second position, which second spacing is smaller than a material thickness (M) of the wall of the tube.
    It is proposed according to the invention that the first, driven roller (3) is set up to grip the tube from the outside in the second position and to rotate it, with the result that a peripheral groove (101) is pressed into the tube in the second position when the first roller (3) is driven.

    摘要： A variable crimp machine includes an actuator adjustment assembly including a dial that rotates about an actuation axis and a barrel positioned along the actuation axis within the dial. The barrel includes a first set of axially spaced markings corresponding to a first hose and a second set of axially spaced markings correspond to a second hose. The dial includes a first set of circumferentially spaced markings corresponding to the first hose and a second set of circumferentially spaced markings corresponding to the second hose. The first set of circumferentially spaced markings are used in concert with the first set of axially spaced markings to adjust an actuator for use with the first hose, and the second set of circumferentially spaced markings are used in concert with the second set of axially spaced markings to adjust the actuator for use with the second hose.

    摘要： A pipe flaring device is described. The device includes a main body extending along a mainly longitudinal direction. The main body also includes a flaring unit. The flaring unit interacts with an end of pipe to be flared. The main body also includes a die carrier arranged at the front of the flaring unit; and a flaring die. The flaring die includes a center channel which houses the pipe to be flared. The device includes a conical inner surface whose tapered end diverges towards the flaring unit and so that the inner surface matches a conical outer surface of the flaring die.

    摘要： A multi-component quick assembly handle includes a first tubular member made of a permanently deformable material and having a first end permanently formed with a predetermined diameter (x) and connecting to a second end forming a remaining portion of said first tubular member of a smaller diameter (x−Δa), a second tubular member made of a permanently deformable material having a first end with a predetermined diameter (x) and connecting a second end having a larger diameter (x+Δb) and an inner diameter (y) to complementary receive by way of a friction fit said second end of said first tubular member. A method of forming multi-component quick assembly handle employs male and female tools to accomplish this.

    摘要： Systems and methods for providing tube end forming equipment or machines that utilize the advantage of hydraulic power without having the constant noise, heat, and energy usage associated with traditional hydraulic power units. The end forming machine includes a hydraulic pump that is operated only when a demand from the system for oil pressure/flow is present. This is accomplished by providing a synchronous servo motor and servo drive coupled to a fixed displacement hydraulic pump. The oil pressure of the system is monitored to detect when the pressure drops below a preset value to provide closed-loop control of the servo motor. The servo motor is controlled to rotate the hydraulic pump at the required speed (up to the maximum RPM of the motor/pump combination) as necessary to obtain the desired system pressure during the tube end forming process.
