The invention relates to a method for producing highly dimensionally accurate, deep-drawn half shells having a bottom region, a jacket and optionally having a flange, wherein a half shell pre-formed from a blank is formed into a finished half shell, wherein the pre-formed half shell has excess blank material on account of its geometrical shape, and the half shell being upset by way of at least one pressing operation in an upsetting tool to form the finished half shell during the forming of the pre-formed half shell into its finished shape on account of the excess blank material. The object of specifying a method and an apparatus, by way of which the process reliability can be increased during the production of a half shell, is achieved by way of the abovementioned method by virtue of the fact that the size of the upset gap is reduced during the closing of the upsetting tool to the actual wall thickness of the jacket of the pre-formed half shell. In addition, the object is achieved by way of an upsetting tool according to the invention by virtue of the fact that two side walls are provided which, together with the bottom region of the die of the second tool half, form a corresponding die, and the side walls can be displaced perpendicularly or obliquely with respect to the movement direction of the die.

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 (xa), 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+b) 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.

The present invention discloses a swaging die holder for the flexible shaft operations. In the preferred embodiment, the swaging die holder comprises of an elliptical die holder slot, a stress relief slot, a radius curve, a recess and an insert. The die holder slot at top of the die holder allows each die holder to mount to the machine. The insert is adapted through the recess at the bottom of each die holder and designed to produce the different output profiles at the end of the flexible shaft. The insert is made of HSS material with cobalt content to achieve optimal life. The insert is further re-grinded or re-sharpened for same or other profile applications of the flexible shaft.

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.

A radial press is provided for the radial deformation of a workpiece centrically to a pressing axis, having two yokes and a pressing tool that comprises a pressing jaw set received in a tool installation space defined between the yokes with pressing jaws arranged concentrically round the pressing axis, wherein both yokes are movable relative to one another by means of a drive system along a drive axis arranged perpendicularly to the pressing axis and the spacing of the pressing jaws from the pressing axis depends on the position of the two yokes relative to one another.

An improved opening for a metal faucet has an outlet neck having an opening with an outer threaded section at an outer edge and a curved stopping ring at the opening, the stopping ring having a rounded surface at an inner edge. The improved opening for a metal faucet which does not have any sharp edge and provide smooth water flows.
