4.4 Cutting Torch Holding Device
The cutting torch holding device is mainly composed of connector, lifting hand wheel
assembly, etc.. The height of cutting torch can be manually adjusted; the verticality of
the cutting torch can also be adjusted to assure vertical incision. Therefore, when it is
required to cut edges and grooves sometimes, biased cutting is available vertically.
The lifting direction of cutting torch can also be rotated.
4.5 Fluid System
After the machine adopts gas inlet through oxygen pipeline and gas pipeline, a tee
joint is used at the head of the horizontal guide rail to divide the oxygen to preheating
oxygen and cutting oxygen. The cutting oxygen will enter the cutting torch through
two-way regulating valve via solenoid valve. The remaining two pipelines will
directly reach the cutting torch through two-way regulating valve.
5. Machine Maintenance and Preservation
5.1 Machine Cleaning
The workplace and working environment of cutting machine are relatively severe.
Therefore, comprehensive cleaning and maintenance of the machine shall be carried
out on a regular basis. In order to assure stable operation of machine and clear cutting
surface, it is required to use clean cloth to wipe all vertical tracks and horizontal
aluminum alloy guide rails constantly and apply a layer of oil film. Besides, all guide
pulleys and idler wheels shall be constantly cleaned. If they are not cleaned, the
oxidized iron rust and various kinds of dust generated during cutting will be attached
on their surfaces to cause abrasion of such parts within a short period, thus resulting in
instable operation of machine and unsatisfactory cutting surface quality.
Keep favorable gearing between gear and rack, which is the key to guaranteeing
normal operation of the machine. Therefore, pay constant attention to absolute
cleanness of vertical and horizontal output gears and racks of the machine. The best
