Schuler forging presses supplied to China

Schuler is supplying two forging presses to Shandong Shantui Construction in Jinging, China, to help the company modernise and expand production of crawler trucks and support rollers.

The order for two forging presses was awarded to Muller Weingarten, a subsidiary of the Schuler Group.

Schuler's experts are beginning assembly of the two presses and automation equipment.

Production is due to start on the new lines in October 2009 and will result in a significant increase in output.

Herbert Pfeiffer, head of project management for solid forming at Muller Weingarten, said: 'The requirements are particularly high in this field of solid forming.

'The two new lines will be used to manufacture chain links and deflection rollers for the crawler tracks of construction machines.

'These parts must be able to withstand tremendous loads.

'The solid forming processes must therefore not only be efficient, but also extremely accurate.

'The two presses were designed and adapted specifically to meet these requirements.

The chain links will be produced in future on a crank forging press.

With a press force of 31MN (3150tonf) and a maximum of 40 strokes/min, the steel blanks are formed into chain links in five die stages under one slide.

The press comprises a mechanical slide and bed ejector, as well as a slug feeder for the automatic feeding of blanks from the induction furnace into the press.

Inside the press, an electronic transfer system handles the automatic transport of parts to the various forming stages or operations.

A cooling and lubricating system is integrated into the press to cool and lubricate the die.

It is moved automatically into the die area via the slide after each press stroke.

Pfeiffer added: 'This solid forming process is capable of producing 20 chain links per minute.

'The product was previously manufactured at a rate of just eight parts per minute.

Schuler's experts have developed a machine which is ideally suited to the needs of this forging environment, with low energy consumption and simple operator handling for semi-automatic die changing, for example.

The line exploits the benefits of a forging press as its forming speed is adapted to the specific process and not only guarantees high part quality, but also long die service lives.

The track support rollers that guide the tracks of the construction vehicles will be manufactured on the second Schuler line.

The screw press with direct drive and a spindle diameter of 450mm features an increased press force of up to 32MN (3200tonf).

The direct drive system with AC motor ensures up to 16 strokes/min.

The line also includes two robots for feeding the steel blanks into the press and for removing the formed rollers out of the press and transferring to the downstream trimming press.

The machine is equipped with a hydraulic slide and bed ejector, while the peripheral equipment of the screw press includes a robot with a die cooling and lubricating device.

Both presses feature the Mueller Weingarten Forge Control System (MW-FCS).

This makes it possible to run the line in all operating modes - such as set-up, die positioning, manual or automatic operation.

Users can also select complete blow programs - with individual settings for the number of blows, energy per blow and pauses between blows - and then store them separately for each die.
