Fontijne Holland - Experts through experience

Cut to length line

The cut-to-length line transforms coiled slit material into straight sheets with a desired length. The line is designed for use in conjunction with a fully automatic productionlines or as a standalone machine.

FEATURES:

Design is rigid and easy to maintain
Coil storage car can be selected optionally
Edge conditioning units are easily swapped out to accommodate different material thickness
Separate length measuring device uses a measuring wheel with length fault detection in combination with encoder of servo motor
Shear blades are easy to change and very accessible

Stacker / Destacker

The stacker/de-stacker has been designed to serve as a buffer between the cut-to-length line and the preparation line. Herewith the preparation line can produce continuously during the changing of coils at the cut-to-length line.

FEATURES:

Continuous production during coil change of cut-to-length line.
Pick-up of stacked strip by an anti-stick system.
Scratch preventing stack/de-stacking of strips.

Coiler / Flattener / Marker

The marker/coiler/flattener has been designed to mark and coil the strip into a ring and to press the ends of the ring into flat ends in order to ensure positive clamping of the ring at the DC-welding machine.

FEATURES:

Modular and open design: compared to other various coiler designs where marking, coiling and flattening are combined in one compact machine.
Good accessibility for adjustments and maintenance.
It also results in a splitting up of the cycle time; not all movements are compressed into one cycle, which leads to a machine which has the potency for very high output.
Flexibility in design and upgrading: modules are available in different versions, which also gives the opportunity to upgrade an existing machine, for example by replacing a medium speed module by a high-speed version.
In the coiler the strip is bend downwards; after coiling the coiled strip is hanging over the lower roll with the opening upwards. This results in less vibration, less noise and easier sliding into the flattening press.

Welder loader

The welder loader has been designed to transfer the coiled ring from the flattener to the DC-welding machine. The flat ends will be aligned in axial and tangential direction to secure a perfect loading of the ring at the DC-welding machine.

FEATURES:

Flexibility in design and upgrading: modules are available in different versions, which also gives the opportunity to upgrade an existing machine.
A continuous gap-control between both ends of the ring guarantees a constant weld quality.
Good accessibility of the DC-welding machine.

DC-welder

The DC-welder has been designed to weld the coiled ring into a ring. The design is made to eliminates most of the disadvantages inherent in conventional types of welding-machines presently in use in the industry.

FEATURES:

No mechanical adjustments necessary for material-thickness, blank width or diameter within the range of rims specified.
Automatic compensation for possible taper shape section of blank material.
Height of each of the two electrodes is automatically adjusted to compensate for re-machining, independent from each other.
Weld centre-line always in same position between electrodes.
Left-hand and right-hand versions of welder are identical.
Upper electrodes have parallel movements, resulting in equal pressure distribution/current on coil.
Both lower electrodes independently adjustable.
Lower machine weight, resulting in less necessary power and faster movements
Service friendliness by placing of the clamping cylinders to the outside of the machine-frame
All rotating bearings are of the self-lubricating type.

Welddresser

The Fontijne Holland weld dresser is designed to automatically trim, roll and side trim the weld rim blanks. The installation is designed as a modular construction, in which a number of sequential processing units are mounted on a common frame at a fixed distance from each other.

THE TRANSPORT OF THE RIM BLANK IS PERFOMED BY:

Swing arm: removes the blank from the welder and presents it to the first processing unit, which is the trimmer
Conveyor: a common automatic conveyor shuttle mechanism loads and unloads the various processing units in such a way that the weld is always in exactly the correct position

FEATURES:

A minimum of machine adjustments necessary for material thickness, blank width or diameter
Modular and rigid design
Additional processing units can be selected on requests by the customer
Option for integration of flaexpander, for re-rounding the flat part of the ring and forming the flare
Rigid design of weld trimmer movement, resulting in an excellent trim result

Flaexpander

The flaexpander is a hydraulically operated expander and has been designed to combine two functions:

Reround of the flat part of the ring
Forming of the flares at the ring

FEATURES:

Combination of two machine operations in one machine which results in less investment costs.
Good accessibility and maintenance.
Crack detection on the ring edges to prevent damaging of tooling further on in the production line.

Roll formers

The heavy duty open-end roll former has been designed for cold forming of a profile in a rim blank. By mounting three of these machines together and adding a loader, a fully automatic three-stage profiling unit is created, to be used in modern high-speed rim production lines. A loader beam with four grippers, in front of the roll formers, transfers the four rim blanks simultaneously to the next operation step.

FEATURES:

Less energy consumption, due to the electric spindle drives.
The main frame is a rigid welded construction, which results in a minimum of deflection of the two spindles.
Low maintenance costs due to the application of closed bearing housings for the spindles and good accessibility.
Tool change can be realized easily and in a very short time.
Re-adjustment of the various settings is reduced to a minimum.
No grease lubrication by using a closed-circuit lubricating oil system.
Adjustment of the parallel position of the lower spindle to correct possible deviations in tooling.

Final expander

The purpose of the final expander is to calibrate rims coming from a preceding roll forming process. This calibrating operation is realized by overloading the material beyond the elasticity limits, in order to obtain a permanent deformation.

FEATURES:

Accurate tolerances of expanded rim blank.
High production rate of the final expander.
Easy tool change outside the machine by an additional set of expander heads.
Less energy consumption.
Automatic grease system.

Rim edge conditioner

The purpose of the Fontijne Holland rim edge conditioner is to reduce or eliminate burrs around the inboard and outboard circumferential of rollformed rims. The burrs are generated as an undesirable result of traditional rollforming of the requested rim profiles.

These burrs are undesirable for a number of reasons:

Cosmetic concerns: the paint does not adhere well, leading to premature corrosion
Operator safety: sharp edges can cause injuries
Product safety: in more severe cases, the edge can actually cut the new tire when wheel and tire are assembled together

FEATURES:

Effective operation: simply de-burr the edge or generate a specific shape
Automatic operation means that no dedicated operator is required, lowering operating costs
The machine has a compact, space-saving design; it can therefore also be installed in existing lines without the need to relocate major equipment
Modern concepts have been incorporated into the design, such as quick die change
A wide range of products can be processed, allowing for varying diameters and widths
The machine is suitable for both drop centre and semi-full face types of wheels.

Leak detector

The leak detector is developed to check the quality of rims by checking the presence of any leaks. The leak detector has been designed as a self-standing unit, for automatic operation in a rim production line. The principle of detecting brings a very reliable indication about any leakages in the rim. The test principle is based on the detection of extreme small air flows at the total weld area surface.

FEATURES:

Very reliable measuring system.
Not sensitive for shocks and chemical influences.
Compact design, so less floor space required.
No additional costs (like helium).
Clean process.
No high air pressure necessary, max. 3 - 4 bar is sufficient.

Valve hole press

The Fontijne Holland pneumatic/hydraulic-actuated punching installation is designed to make the valve holes in rims by performing the following sequential operations:

Coining of the valve hole area
Punching of the valve hole
De-burring of the valve hole on both sides

FEATURES:

Compact design and easy to maintain
The precision indexing table with clamping devices assures the correct position of the valve hole during transport to the various processing units
The pneumatic/hydraulic cylinders are maintenance- friendly and energy saving, since there is no hydraulic system
Easy to integrate optional leak detection installation before valve hole punching

Assembly line

The assembly line has been designed to load the disc and the rim correctly to an assembly press which presses the disc at the correct position into the rim. The preassembled wheel will be welded at assembly welders. Transfers and robots are integrated for the correct loading and unloading of the equipment.

FEATURES:

Automatic disc and rim orientation.
Disc attached in the well and the bead seat possible.
Modular and open maintenance friendly design.
Tool change can be realized easily.
Reduction of spatters on assembled wheel by special tooling.

Measuring machine

The measuring machine has been designed to measure accurately the physical run out characteristics of finished wheels. The measuring machine is a self-standing unit, for single use operation or automatic operation in a production line.

FEATURES:

Measuring of axial run out bead seat in- and outboard.
Measuring of radial run out bead seat in- and outboard.
Calculation of 1^st to 4^th harmonic of each measured features.
Averages and standard deviations for all measurements.
Match point via vectorial addition of 1^st harmonic of the radial run out outboard side and inboard side.
Tolerance check of “good” and “bad” wheel.
Marking of low or high point of the average 1^st harmonic of radial run out by means of a dimple at the flange of the short bead seat.

Single machine equipment

Fontijne Holland is able to supply single machines of wheel production line equipment. As a result, customers are able to expand their existing equipment by adding a separate process unit if necessary. For example, loading and unloading could be handled by a robot.

Flowformer for passenger car rings

The Fontijne Holland flowformer is developed to locally reduce thickness of the material on sheet metal rings, with the purpose of manufacturing weight-optimised rims.

The machine is suitable for use in new rim profiling lines and can be added to existing lines. For existing lines, tooling must be adapted. In addition, the flare operation must be checked whether it is capable forming the required flare shapes. The flowformer is capable of reducing the material thickness of a flared ring in places where the rim does not require the original metal sheet thickness.

The flowformer is located between the preparation line and the profiling line.

FEATURES:

Newly developed user interface
Flexible recipe control
Online support and user interface
Different user levels available for operation and maintenance

Run out reducer

The run out reducer has been designed as a hydraulically operated four column vertical press with a basic toolset for press mounting that can be easily adapted to the typical requirements for the run out reducer operation. The run out reducer is a self-standing machine and will be used normally off line a production line.
