Method and upsetting tool for producing highly dimensionally accurate half shells

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.

Copper pipe bending tool
10052672 · 2018-08-21 ·

The copper pipe bending tool is a cylindrical tool that is inserted into the open end of a copper pipe or copper tubing and which provides a grasping point and leverage over the end of the piping. Using the copper pipe bending tool makes it easier to move or bend the piping to align it with a specific fitting where it needs to connect. The tool may provide an interface area for copper pipes of several different standard sizes. The tool may also provide a texture grasping area to help prevent the user's hand from slipping off of the tool while in use.
