Electrical sheet special solutions

Normally, a tool change on a groo­ving press takes less than 10 minutes.

A groo­ving press produces rotor and stator lami­na­tions for elec­tric motors and gene­ra­tors using the single groo­ving process.
The stamped metal sheets are assem­bled into packages and then wound or moulded and assem­bled into a motor or generator.

Slot punches are used to manu­fac­ture elec­trical lami­na­tions (stators and rotors) for elec­tric motors.

A single groove is punched into a circular sheet using a punching tool.
The sheet is then fed through a feed device (divi­ding head) by one divi­sion – the punching process is repeated.
Depen­ding on the pitch, between 30 and 100 punching opera­tions are carried out per sheet until the finished sheet is produced. This takes place at a stroke rate of 600 to 1200 punching opera­tions per minute.

The produc­tion of sheet metal using the single groo­ving process is consider­ably cheaper and more flexible compared to a mould with a complete cut.

As a rule, the groo­ving press is operated at 600 to 1200 strokes per minute. This depends on the size and comple­xity of the component.

We curr­ently offer groo­ving punches in a range of 5 – 20 tonnes punching force.

Slot punching at the highest level and maximum precision and output. The patented design of the groo­ving press enables high rigi­dity and optimum condi­tions for good auto­ma­tion.
Thanks to the drive tech­no­logy used, there are no more wearing parts on the groo­ving press.

We offer custo­mised solu­tions for the mecha­nical and elec­trical moder­ni­sa­tion of old groo­ving presses. In addi­tion, exis­ting groo­ving presses can be retro­fitted with our auto­ma­tion concepts.

Depen­ding on the size and degree of auto­ma­tion, the output of our systems is between four and ten sheets per minute.

It usually takes around 10 months from orde­ring to deli­very of a groo­ving machine. We often have a demons­tra­tion machine in-house that is available at short notice.

The groo­ving machine has a modular design and is very easy to main­tain, as the groo­ving machine no longer has any wearing parts.

Hagel Auto­ma­tion specia­lises in the design and cons­truc­tion of slot­ting machines and the entire auto­ma­tion process. Hagel Auto­ma­tion supplies effi­cient, modern and highly precise slot­ting machines.

The costs depend on the required punching force, the equip­ment and the degree of auto­ma­tion of the groo­ving press. We are able to prepare a quota­tion for any appli­ca­tion at short notice.

Curr­ently, sheet metal with a diameter of 35 mm to 1300 mm is processed on groo­ving machines. The current trend is towards larger diame­ters of up to 1800 mm.
