Combined thread rolling machine
06 June 2016
TLM Srl is always working on new projects to develop innovative technologies aimed at supporting various needs in its customers’ production. An example is the upgraded modular systems that it has been creating for over 15 years, which enable the execution of different processes on the same part.
Using modular composed machinery it is possible to obtain various kinds of threading in addition to different finishing operations, such as grooves, points, and the assembly of washers – all simultaneously on the same fastening component.
The RP16 is a thread rolling machine with flat dies that can thread up to a diameter of 16mm, but with a higher die pocket than the standard version, which enables the user to create a component with two threads of the same diameter but at a very high intermediate distance.
A special module comprising a roll and sector thread rolling machine (rotary unit), with tools positioned to perform threading over the head, and grooves under the head, is mounted behind the machine on the bypassable carriage – even though the piece is a considerable length.
At the rotary unit output guides take the pieces and bring them to their final threading on the flat die machine without exiting the system. In this way the machine can carry out two different processes in a single step and, above all, with a single load, with one process performed while the machine is working on another piece.
This creates a multi-functional machine that enables a single load of components for rolling. The elimination of subsequent unloading and loading to perform other processing steps on the component, reduces the risk of damage to the previously created threading.
TLM points out that these systems are extremely versatile, due to the fact the modules can be combined in different ways depending on the component being processed. Machines with sharpener, washer loader, and rotary unit rolling machine modules – once assembled on carriages – can be moved laterally, therefore enabling the passing from one production step to another simply by operating the necessary modules.
“The increase in productivity of machinery deriving from use of these modules enables our customers to optimise their production while cutting back on execution times and product prices, which are continually more complex, above all in the automotive industry.”
