29 Speed Control TM SPC GAS Springs, cushioned APPR O VED 97/2 3/EC k f227

30 Speed Control TM, SPC Gas Springs, cushioned Description FIBRO SPC Gas Springs»Speed Control TM «have been engineered to reduce or eliminate blank holder bounce; commonly associated with increased return speeds form link drive presses. SPC Gas Springs have inbuilt return speed dampening, which decelerates the last 30 mm of piston rod to 0.4 m/s, helping to bring the blank holder to a smooth stop. Benefits of the»speed Control TM «SPC Gas Springs, cushioned: I Eliminates blank holder bounce. I Increases productivity by more increasing part transfer efficiency. I Easily retrofitted to existing dies. I Stroke lengths 125 to 300 mm. I Linkable using hose system k F228

31 Speed Control TM, SPC Gas Springs, cushioned Performance: Strokes per minute, depending on length, at max. 150 bar charge pressure* The diagram shows the max. possible number of s per minutes [min-1] of SPC gas springs with a max. filling pressure (150 bar) and max. used lengths before there is a risk of excessive heating. max s per minute (spm) Note! The number of s per minutes can be doubled by halving the initial filling pressure. Caution! SPC gas springs are subject to a higher heating than standard gas springs. For this reason, please ensure adequate ventilation of the SPC gas springs in the tool. Stroke length of SPC in mm *At ambient room temperature with free air flow Function Example Travel of blank holder per unit of time Blank holder without SPC Blank holder with SPC SPC reduces speed to 0.4 m/s Press speed 1.0 m/s Installation k Stroke in mm Time in s»speed Control TM «SPC Gas Springs gave a 90% reduction of blank holder bounce. It is important that approx. 25 to 30 mm before the sheet metal retainer has reached its home position, only SPC gas springs are applied. Therefore, for the retrofitting of existing tools with SPC gas springs we recommend the following two options: Option 1 replace all gas springs with SPC gas springs Option 2 corner solution (see below) Dampening length (~ 30 mm) Please note: Springs must be installed with a recess of 25 mm to balance the total length difference (2 x length = 50 mm). Alternatively, the contact surface of the sheet metal retainer can be recessed in order to achieve the same effect. F229

Mounting with a threaded flange plate has the advantage of a degree of adjustability as far as the flange screws permit, Moreover it is often found easier to make do with a clearance hole in the tool plate.

65 LCF gas springs, damped f263

66 LCF gas springs, damped Description The LCF series represents a whole new generation of nitrogen-filled gas springs developed to meet the needs of the machine tool and press-making industries. Negative factors such as I high impact stresses I excessive noise I extreme bounce off the pad are all minimised by LCF springs. Characteristics such as I dimensions I fixing methods I filling with gas and purging I working in interconnected systems are identical to those for standard ISO or type gas springs. The springs from the LCF series reduce impact stresses by 50% compared to conventional gas springs. The force builds up gradually and acceleration is uniform, reducing wear on both tool and press. As a result, less maintenance is required. LCF springs are at least 20% quieter than standard gas springs. The reduced noise level is due to the lower impact force, making these springs a cost-effective alternative to soundproofing panels. They are thus more economical and environmentally-friendly. The LCF springs reduce the extreme bounce off the pad during the return, thus lessening vibration on the workpiece and allowing the workpiece to be transported more effectively. Since the spring travel is damped, the pad motion is more uniform, so in many cases the press rate and thus productivity can be increased. * LCF Force Manager is a trade mark of Associated Spring F264

Note: Maximum pressure for LCF gas springs: 150 bar. Observe minimum filling pressure. Guidelines for the use of LCF gas springs 1. After the damped spring travel (S 1 ) the LCF gas spring achieves the same initial spring force (F 1 ) and pressure build up as the standard gas spring (to ISO). 2. The spring force (F lcf ) should exceed the weight (e.g. the pad) by at least 15% so that it is held in the correct position (this does not apply in the case of minimum filling pressure).
