130mm Tube Bending Machine

Solution - Client: Alexander Dennis, Surrey, UK

CUSTOMER PROBLEM:

Alexander Dennis were looking for an electro-pneumatic tube bending machine to replace an existing hydraulic unit - they wanted something that could handle a wider range of tube sizes and shapes at a lower cost. They are a leading manufacturer of single, double deck buses and coach chassis. The machine would be required to bend many of thier in house production of tubular components such as hydraulic brake pipes, air conditioning and exhaust pipes.

UNISON SOLUTION :

To supply a 130mm Breeze Single Stack machine

In place of hydraulic force, the Breeze 130 employs servo motors to control the bend process, including clamp, pressure die, mandrel and follower. This all-electric actuation provides significant benefits related to energy consumption, repeatability, and noise reduction. As the actuation elements of the machine only draw significant current when a bend is being made, energy usage is greatly reduced.

The fast, software-controlled set-up of an all-electric tube bender is very well suited to the bus and coach manufacturing process, as the production batch sizes tend to be small.
