The placement of Plate Speed Clamps for HEIDELBERG KORD

Before you place the new speed clamps onto the machine, please check that the two register pins N16 & N18 are at their correct side. If they are placed incorrectly, they will need to be changed to the correct sides by loosening the small screws (fig.9) that hold them. The difference between the two sides of pins is shown below in sketches A & B. If you use plates with no holes then you remove the two register pins. If in future you use plates with holes, you reinstall them very easily and simply.

Before you start the placement of the new speed clamps, clean the grooves of the cylinder well. Place a fine coat of grease at the bottom of each clamp and on the two sides (fig.1) where the trip blocks hold the clamp in the cylinder. Place the front clamp in its position after you have first placed the four springs K17 in their positions.

Screw the side trip blocks at their position. In order to place them easily, use a steel strip of 0,1mm thickness between the trip block and the clamp. Tighten well their screws and then remove the steel strip. Continue with the placement of the indicator sets and the hexagon knuckled nut on the headless middle screw. Pay attention to the conical socket washer G15 so that is placed on the correct side. The conical side (fig.10) will be adjacent to the corresponding side of the hexagon adjustment holders G17 and to the hexagon knuckled nut G16. When you finish the placement of the indicator sets and of the hexagon knuckled nut of the front clamp, place the split pins (fig.5), secure them and place along with the security spring washer (fig.7) the socket button flange head screw on the headless middle screw. Place the rear clamp in its position, screw and tighten the trip blocks, in the same way as you did in the front clamp. Screw the hexagon knuckled nuts G16 provided that you have first placed the conical socket washers G15 on the right side. Place along with the security spring washers the three socket button flange head screws (fig.7) on the headless screws. The upper and lower part of the clamps are connected together with a series of Hexagon socket countersunk head screws N02-M8X20 that are for adjusting, when required, the pressure that holds the plate. The adjustment is always regulated with the plate tightened. For the above adjustment, you must use a long hexagon socket key 5mm by moving it only a little. You have to use some strength because the above screws are secured with a plastic ring N50/N55.

There are compression springs N06 between the two parts of the clamp that help to open the upper part (of the clamp). The hexagon socket head cap screws (fig.2) are only to keep the adjustable studs K16 which have to be moved slightly tightened. The upper clamp opens and closes with the pin wrench with handle N46. In order to close the clamp, you have to move it forward to the lid end (fig.8). For the opening of the clamp, the pin wrench has to be moved backwards until you feel that it has fallen into a flat gap. The placement of the clamps in the center of the cylinder or the arrangement of the left and right is done with the two adjustable studs K16 on which there are indicators (fig.3) to show that the clamps are in the center. The adjustment of the front clamp forwards-backwards, to the correct place, meaning in position “O” for the start of the placement of the new plate, is done with the two sets precise indicators G12 & G13. Each set of indicators has two x two hexagon socket set screws (fig.4) which with a hexagon socket screw key 2mm, regulate or adjust the position “O”. Basically the operation of the new speed clamps is the same as the old ones. The difference is that these speed clamps hold the plate securely, permanently and are for a long life use.
