Control and automation

Updating control systems enables more precise and effi­cient processes. The imple­men­ta­tion of auto­ma­tion tech­no­lo­gies can increase produc­ti­vity and improve user-friendliness.

 

Mate­rial supply and removal
Impro­ving mate­rial supply and removal systems can help to make the produc­tion process smoother and more efficient.

 

Quality control
The imple­men­ta­tion of modern quality assu­rance systems, such as image proces­sing tech­no­lo­gies and special sensor tech­no­logy, can monitor and ensure the quality of the stamped parts

 

Spare parts management
Updating obso­lete compon­ents and swit­ching to more modern elec­tronic compon­ents in elec­trical engi­nee­ring can play an important role in the moder­ni­sa­tion of groo­ving presses. This is parti­cu­larly important if the old compon­ents are no longer available or are diffi­cult to procure. New elec­trical compon­ents are gene­rally not only more effi­cient, but also available on the market for many years.

 

Sound insu­la­tion
Noise protec­tion is an inte­gral part of our die-cutting moder­ni­sa­tion solu­tions. Our sound­pro­ofing booths can be flexibly confi­gured as stand-alone systems or as part of a fully auto­mated produc­tion line, allo­wing us to signi­fi­cantly mini­mise noise pollution.

Slot cutter MW Retrofit

Compre­hen­sive over­haul and moder­ni­sa­tion of the exis­ting NN20 groo­ving machine.

 

 

General project scope

 

  • Repla­ce­ment of wearing parts and repair work
  • Impro­ving machine effi­ci­ency and precision through targeted modernisation.
  • Renewal of critical compon­ents to increase the service life and perfor­mance of the groo­ving press.
  • Inte­gra­tion of measures to ensure opera­ting safety and compli­ance with industry standards.
  • Conver­sion to modern control and auto­ma­tion tech­no­lo­gies for optimum process control and efficiency.
  • Adapt­a­tion of the groo­ving press to chan­ging produc­tion requi­re­ments and materials.
  • Compre­hen­sive project support from plan­ning to commissioning.

 

Tappet and drive
The slide guide rails were replaced to restore the punching accu­racy. In addi­tion, the slide guide compon­ents were assem­bled and adjusted for optimum precision and parallelism.

 

Wear parts
The pulley and V‑belt were replaced and the bearings over­hauled. The flywheel shaft was replaced to ensure smooth operation.

 

Revi­sion of the rotary table
A blank clamp was retro­fitted to enable punching without a blank holder.

 

Main drive Siemens 1PH8
A new main drive from Siemens was inte­grated. At the same time, the servo unit for the pitch circle adjus­t­ment was replaced.

 

Clutch/brake combi­na­tion Service work
The wearing compon­ents of the clutch/brake combi­na­tion were replaced to ensure safety and performance.

 

Elec­trics
The control systems and elec­tro­nics were compre­hen­si­vely modernised.
Advanced control tech­no­lo­gies have been inte­grated to improve process moni­to­ring and efficiency.

Questions and answers

How long does a tool change on a grooving press take?

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

What does a groove punch do?

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.

Which parts are mainly produced on grooving presses?

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

How does a groove punching machine work?

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.

What are the advantages of a groove punch?

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

How fast is a groove punch like this?

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.

How many tonnes can a grooving machine punch?

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

Why a Hagel Automation grooving machine? 

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.

Modernise or replace old grooving presses?

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.

How large is the output of a grooving machine?

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

What is the delivery time for a groove punch?

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.

How easy is it to maintain a grooving machine?

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

Who supplies grooving presses and builds the automation for them?

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.

What does a groove punch cost?

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.

How heavy is a groove punch?

Approx. 4000 to 7000 kg.

What are the areas of application of a grooving machine?

Produc­tion of elec­trical sheets for motors and gene­ra­tors for wind power, hydro­power and drive technology.

How does the single grooving process work with grooving punches?

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.

What sheet diameters are possible on a grooving press?

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.
