Slot punching centre as a tandem line

Our slot­ting centre as a tandem line includes complete auto­ma­tion for all aspects of slot­ting. This enables effi­cient and cost-effec­tive, fully auto­mated proces­sing of elec­trical sheets of any size.

 

Slot­ting centres are essen­tial for the produc­tion of elec­trical sheets and stand for precision, flexi­bi­lity and speed.

 

We offer custo­mised solu­tions that take into account the indi­vi­dual needs of our custo­mers and deliver a tailor-made solution.

 

We have been a reliable partner for our custo­mers for decades. We offer not only high-quality products, but also excel­lent service and compre­hen­sive advice to ensure that our custo­mers receive the best solu­tions for their produc­tion processes. We work closely with our custo­mers to develop indi­vi­dual solu­tions and deliver custo­mised produc­tion lines that meet the specific requi­re­ments of each customer.

Linear feeder

The sheet metal trans­port through the entire system is realised by speci­ally deve­loped linear feeders. These provide safe and fast trans­port and optimum acces­si­bi­lity for the set-up processes.

 

Tooling

Newly deve­loped tooling enables extre­mely fast set-up processes. By redu­cing the number of compon­ents, the suscep­ti­bi­lity to faults is signi­fi­cantly reduced.

 

Offset filing

Depen­ding on the size of the finished discs, several stacks can be offset on a pallet.

 

Sound insu­la­tion

The sound­pro­ofing elements are inte­grated into the machine frame and ensure a signi­fi­cant reduc­tion in noise pollution.

 

Modular design

The punching centre has a modular design and can be expanded accor­ding to requi­re­ments and functions.

Produc­tion of rotor and stator lami­na­tions in one work step

In a tandem slot punching centre, one rotor and one stator plate are produced in a single work step.

 

Variable use in production

Both groo­ving punches of the punching centre can be operated inde­pendently of each other as a “single” groo­ving centre.

Both parts of the system can also be operated toge­ther as a tandem groo­ving centre.

To enable stag­gered set-up, the sheets can be passed through directly, or alter­na­tively the pallet can be fed to the second part of the system via a corner transfer unit.

 

Use of 2 stacking and destacking stations per system section for unin­ter­rupted production

The use of 2 stacking and destacking stations ensures unin­ter­rupted production.

 

Auto­matic loading and unloa­ding of pallets

The pallets with the sheet metal stacks are posi­tioned on the chain conveyors and trans­ported onwards through the system accordingly.

 

Double sheet detection

Measu­re­ment of the sheet thic­k­ness to prevent the feeding of double sheets.

 

Sheet metal rolling func­tion inte­grated in tooling

Sheets are sepa­rated from each other by lifting the suction cups locally, thus ensu­ring that only one sheet is removed from the stack and fed in.

 

Optical measu­re­ment of the elec­trical sheets

The sheet metal blank is photo­gra­phed and measured accor­ding to the sheet charac­te­ristics. The sheet metal is then aligned in the x and y direc­tions, as well as the c‑axis, so that the sheet metal can be precisely inserted into the groo­ving press.

Slot cutter as tandem line in U‑shape

 

In this appli­ca­tion example, a groo­ving centre is desi­gned as a double single groo­ving press. Produc­tion can be carried out inde­pendently on each part of the system.
Both parts of the system can be linked toge­ther via a transfer point and the system can be used as a tandem system.
This func­tion gives the system operator maximum flexi­bi­lity in production.

Parti­cular emphasis was placed on output and compact­ness as well as easy hand­ling by the operator.

 

The use of 2 stacking and 2 destacking stations ensures unin­ter­rupted production.

 

Thanks to the U‑shaped arran­ge­ment of the system concept, the space requi­re­ment can be reduced and can also be inte­grated into exis­ting produc­tion areas.

The system parts can be set up at diffe­rent times by alter­na­tively linking them via a feeder or via the pallet stack, thus redu­cing down­time and the neces­sary labour costs.

Questions and answers

How long does a mould change take?

Normally, a tool change in a tandem groo­ving press takes less than 35 minutes, inclu­ding tooling of the loader setup.

What does a Tandem grooving centre do?

A tandem slot punching centre is required to punch so-called “slots” out of elec­trical sheets.
Slot punching centres contain both the slot punching machine itself and the entire auto­ma­tion system in a compact and modular design. The tandem system can be used as 2 single systems or as a complete system, in which case the stator and rotor can be punched in a single operation.

Which parts are mainly produced with it?

Elec­trical sheets for the produc­tion of stators/rotors for elec­tric motors.

How does a grooving centre work as a tandem line?

Elec­trical steel sheets are auto­ma­ti­cally fed into the system and sepa­rated, aligned and inserted fully auto­ma­ti­cally into a slot punching centre. In slot punching centres as a tandem line, the stator and rotor can be processed fully auto­ma­ti­cally in one system. Both elec­trical sheets are then stacked with clean edges.
Diffe­rent modes can be selected, e.g. to place blanks in a twisted posi­tion to compen­sate for rolling inac­cu­ra­cies.
An elec­trical steel sheet ther­e­fore usually takes 3–5 seconds, depen­ding on the number of strokes and the diameter of the elec­trical steel sheets.

What are the advantages of a slotting centre as a tandem line?

Compared to a solid tool, groo­ving centres are cheaper to purchase. The customer can punch diffe­rent products much more flexibly and fully automatically.

How fast is such a grooving centre as a tandem line?

As a rule, the slot­ting centre is operated as a tandem with 800 – 1200 strokes per minute. In Hagel Automation’s tandem slot punching centre, 720 – 1200 elec­trical steel sheets can be produced per hour for the stator and rotor, which are stacked with clean edges.
