Standard Execution :
- Flanging Cycle
- Hydraulically driven flanging roll (both knuckle & flanging rolls are positively driven)
- Attachment for flanging thin walled heads
- Knuckle rolls IKR as per following chart (option for special ones up to customer)
- Attachment to remove and change knuckle and flanging rolls
- Machine pre-setting for later fitting of chamfering attachment
- Centralized greasing system
- Metal telescopic bed guides protections
- Two zero setting digital read-outs :
The first read-out displays the position of the lower head holding carriage.
The second read-out displays the position of the upper carriage, holding the calmping cylinder.
Both read-outs should display the same upper and lower carriage positions before clamping head to be flanged.
The main purpose of the read-outs is to display the diameter od the head being flanged (final or intermediate)
- Lead screws - ball type, no maintenance required - for traverse of the upper clamping and lower head-holding carriages (by SKF, STAR). Carriages can slide during operation while clamping the head.
- The standard machine embodies the possibility of flanging flat heads – flanged only with no set up time and extra device (exclusive Boldrini system)
Special Requirement :
- The machine will be supplied with the heat protection covers by Boldrini design. These covers will protect the electric wiring and hydraulics while flanging hot dished heads.
- Heating with burners while the machine is in operation will not guarantee the productions efficiency.
- An extra head supporting spacer will be included to prevent head supporting bearing overheating.
- It is not recommended to flange thickness over 45 mm (minimum head temperature 1420F)
- The machine quoted is supplied by Rexroth hydraulics
