Offset the installation and commissioning of the assembly and place – offset printing press, the installation – Printing Industry
First, assemble and place the order and benchmarks Delineation of the center line before the first
assembly, the center line to determine there are two: First, shop the center line as the benchmark; Second, the wall as the base. Determination of the center line of the various models according to Offset Area and auxiliary equipment, and other factors taken into account. Such as Heidelberg Speedmaster CD102-type Offset printing Machine, machine center line and the distance between the wall not less than 3.9 meters, or else it will affect the installation and maintenance of ancillary equipment space.
Once the centerline is confirmed, the total length of the machine within a laser level meters for each measurement of the level of the foundation. (See Figure 10-2), first adjusting the horizontal position of the laser transmitter and then measuring the distance between a ~ b, the error can be aware of ground conditions.
Figure 10-2 Schematic diagram of measuring the level of foundation
Ground level height in the measurement, laser party personnel need to be careful not to let laser direct exposure to the eye, so as not to damage the retina. Foundation aims to measure the level of understanding of the installation machine before the smoothness of the foundation in order to correctly determine the height of the first floor unit, to avoid the follow-up units because of the foundation level of error can not be landed.
Machine installed in identifying the center line after the end of the first units off the bits required to program a vertical line with the center line, to determine the correct position of the first unit. The correct positioning of the first unit is critical, such as the slightest error in positioning the first unit, the whole installation will deviate from the machine center line, and finally to the first unit of the oil pan under the machine's center line and vertical lines placed floor, and The first set down in the oil pan, and use an accuracy of 0.02 mm / m level meter on the first unit of the vertical and lateral horizontal adjustment after adjustment to observe whether there is ground subsidence (not less than 12 hours) using the method: the suction box test level position in the base machine, do not move or collision Levels.
2, assembled and in place of the process and the essentials
The first unit in place and level of recognition accuracy of the case before the second unit of the assembly, the lifting (by the crane operators and workers with the machine) process, not a collision phenomenon, in order to avoid damage the machine. In the second set very close to the situation, with a small piece of wood sandwiched between the two groups (anti-collision), when the two units is about 5 cm apart, then use the top, pushing the same time progressively tightened with bolts, to do no collision docking, the key unit in each block of four feet under ground, with two 0.2 mm thick plastic sheets cut to 20 cm × 20 cm in size, the middle of some grease, pad to the ground at the foot of this mobile unit , the resistance greatly reduced after the stitching unit, one by one, take away, the first and second unit stitching is complete, start the second set to level of adjustment. Adjustment method is based on the first unit as the base, with a dial indicator to play second base level units with the first unit to require vertical and horizontal almost zero to zero, and then box-type level, and a test article test level second level and appropriate adjustments. Third and fourth units of the installation of stitching the same with the second unit. In each unit of the fight, we should pay attention to the manufacturer to do the meshing gear marking, if not aligned engagement mark, the machine should be open reload. Finally, to receive paper feeding and assembly.
After the end of the host assembly, further supporting the installation, such as: computer console, water tank, vertical central supply cabinets, electrical boxes, and connect all the lines, install all the pedals, handrails and related devices , the whole installation is complete, check the machine immediately; as before and after the lift, to move, running, constant speed, joint pressure, Dusting , Air pump, water tank (cycling and refrigeration), the function of the computer console and lubrication devices, dust removal equipment, gas line, the safety device and feeding, collection of paper setting function. Inspection is completed, make a trial run, and gradually rose to 15 000 by the low / When running an hour later, one by one check whether the three hot roller shaft phenomena, without exception, installed into the machine commissioning stage.
