This Tracto-Technik Tuboform is a sheet metal working machine — specifically a tube bending machine, sometimes referred to as a pipe bender — designed to form precision steel tubes into accurate bends with repeatable results. Tracto-Technik is a German manufacturer with a long-standing reputation in pipe and tube processing equipment, serving industries that require precise tube forming such as hydraulics, automotive engineering, and mechanical engineering.
The machine processes precision steel tubes manufactured to DIN 2391/C, material designation 35.4 NBK, and accepts tube diameters from 6 mm up to a maximum of 16 mm. It operates as a free-bending machine, meaning the bending head works without a fixed die set constraining the outer radius, which allows for flexible forming across the diameter range. The bending head is pivoting, switching between vertical and horizontal positions to accommodate different working orientations and tube routing requirements.
Bending angle is controlled through an 8-fold preselection system, with angles programmable up to a maximum of 180 degrees, giving the operator reliable, repeatable settings across a variety of bend requirements. A pipe stop with a length capacity of 1 metre is included, allowing consistent positioning of the tube before each bend cycle.
The machine is hydraulically driven, requiring approximately 20 litres of hydraulic oil — such as Esso Nuto 32 or equivalent — and is powered by a 0.75 kW electric motor running on 220 V / 50 Hz single-phase supply. For operator safety, an emergency stop button is fitted as standard.
Despite its capability, the machine has a compact footprint of approximately 1.0 × 0.8 × 1.2 metres (L × W × H) and weighs around 145 kg. It is designed to be mobile, fitted with a parking brake that keeps it securely positioned during operation. A selection of various bending tools is included with the machine. This is a used example dating from 1992, located in Germany.
