4 BRIEF INTRODUCTION TO MACHINE PARTS
4.1 MECHANICAL MOVEMENT STRUCTURE
The mechanical movement structure is composed of the following a series of single parts.
Longitudinal driving device
Composed of longitudinal straight-line guide rail, longitudinal gear, rack, etc..
Transverse driving device
Composed of transverse guide pulley, transverse aluminum guide rail, transverse gear, rack, etc..
Cutting Torch Device
Composed of cutting torch body, two-way valve, gas supply pipe, etc..
Cutting Torch Lifting Device
Composed of lifting motor, lead screw, sliding bearing, lifting holder, etc..
Cutting Torch Holding Device
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.
4.2 FLUID SYSTEM
After the machine adopts gas inlet through oxygen pipeline and gas pipeline, a tee joint is used at the
head of the transverse 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 longitudinal tracks and transverse 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 longitudinal and transverse output
gears and racks of the machine. The best method is to clean and lubricate the rack and track on a
regular basis. The users are suggested to use compressed air to spray longitudinal and transverse rack
