Component Leveller
RANGE OF APPLICATION OF PART LEVELLING MACHINES
Basics
Sheet-metal parts showing uneven surfaces lead to poor quality of the final products. In addition these parts cause higher costs due to subsequent processing and assembling. Unevenness of the parts results from processing methods such as shearing, stamping, nibbling, laser or plasma cutting, hardening and coating caused by changes of internal stresses of the component.
Range of parts
- Parts with a thickness from 0.5 mm to 8 mm, a width of up to 500 mm and up to 5,000 mm in length
- Steel, copper, aluminium, titanium, special alloys, and bimetals up to a yield point of 600 N/mm² at normal temperature and up to a hardness of 48 HRC
- Flat parts and parts with uneven surface
- Parts for device engineering, machine, aircraft and automotive industry
- Parts for electrical engineering and the construction industry
- Saws and cutting tools
- Weaving lamella, housing parts, perforated plates
Roller Levelling
The highest degree of surface evenness can be achieved and internal stresses are reduced remarkably when levelling the parts with a precision leveller. The individually driven levelling rollers level the workpieces through alternate bending. The upper and lower rows of rollers are arranged offset to each other, forming a wedge-shaped profile which opens in running direction. The strongest bending of the material occurs at the inlet where the material is formed until it reaches its plastic state. At the outlet the workpiece is only formed to its elastic state leaving the machine with an even surface.
WHY PRESS ROOM LEVELLERS ARE YOUR PROFITABLE DECISION…
In the range of sheet metal coil feeding automation, Press Room has been redefining the industry standards & have brought out precision levellers for straightening of coils, strips, components, sheets. For precision levelling machines with 13 to 21 rollers are used depending on the thickness of the material. Depending on the kind and condition of the material an accuracy in evenness of < 1 mm per 1000 mm part length can be achieved.
Single Component Leveller
When running through the precision leveller the parts are levelled to the requested evenness during one levelling run. The parts are fed and discharged from the precision levelling machine by means of conveyor belts or roller paths. In case very big pieces are processed a second levelling run might be required. To guarantee easy handling the machine should be equipped with a reversing system. The change of direction as well as the setting of the roller frame in opposite direction are carried out automatically.
Automatic PLC Controlled Part Leveller
A fast and easy setting of the machine is provided due to the block feed system of the levelling rollers. Via a control panel, the input of the set values is carried out. The adjustment of the roller frames is carried out by motor via worm gearing with an accuracy of 0.05 mm. A high performance positioning control guarantees short change over times.
- Adjustment of Levelling Rolls via Servo / A.C. Motor & Drive.
- 10-30 Pats Setting Parameters can be Stored for Quick Retrieval in Future.
- Accuracy of Roll Positioning in Range of 50 Microns.
- Entire Operating Setting by Unskilled Operator, Once pre-programmed.
- Possibility of Two Three Programme for Same Part due to variation of the Input Parameters like Hardness etc.
Twin Component Leveller
Round parts are always levelled in two directions. The most economical solution for series production such as clutch disks is a twin levelling machine. This double levelling line consists of 2 precision part levelling units connected by a turntable. A turntable installed between the two levelling machines turns the parts by 90°. The turning itself is achieved by transporting the parts on two conveyor belts or roller paths running at different speeds. The belt speeds can be controlled in order to achieve an optimum adaption to the part size.
Advantages of twin levelling machines compared to levelling procedures with heat treating:
- Higher output, very short processing times
- Lower investment costs
- Lower energy requirement
- Lower space requirement
- Simpler parts handling
- Higher degree of automation
