Backward Horizontal Impact Extrusion Presses for Aluminium tubes and cans

Metal Forming

Backward Horizontal Impact Extrusion Presses

The Rhodes KJX range of Horizontal Impact Extrusion Presses are designed for the production of non-ferrous (recyclable) tubes and cans such as Battery cases, Toothpaste tubes, Cosmetics, Machine Pharmaceutical Tubes and Aerosol Cans. Press capacity ranges from 5 to 1000 tonnes, to enable the correct machine to be selected for each application.

Group Rhodes manufacture a range of KJX presses designed to eliminate the out-of-balance forces, or convert them from the horizontal to the vertical plane, in order to ensure smooth running at high speeds. This is achieved with a radical new linkage design and dual balancing system, which reduces stress and shock loads within the press. Furthermore, to ensure smooth running and minimum vibration, the crankshaft and knuckle linkage have been dynamically balanced using the latest Computer Aided Design technology and now operate within a rigid, fully-stress relieved, one piece steel fabricated frame.

To meet new production demands, non-ferrous calots are automatically orientated before being fed down the chute in front of the tool to be backward extruded. After extrusion, the can or tube is stripped from the punch onto a continuous conveyor, which in turn supplies the complimentary machinery developed to run at the new high speed.

Additional features include:

An AC variable drive motor to ensure the automatic speed changes are performed quickly and safely.
An Ergonomically redesigned toolspace area with improved accessibility.
Precision engineered double helical gears rotating in a sealed oil bath.
A Can Take-Off System, which is independently adjustable for timing, and protected by an overload clutch.
The highly successful 'Ortlinghaus' combined pneumatic friction clutch and brake unit.
A fully automatic 'full flow' recirculating oil lubrication system using internally machined oilways, thereby reducing the need for vulnerable flexible pipework.

Optional extras include

CNC or PLC Technology
Motorised slide adjustment
Bowl feeders
Feed system
Hopper elevators
Ejectors and Compensators
Soundproof Enclosures
