Pillow plate welding machine
I.No. 1 CNC CONTROL DEVICE FOR WELDING STAINLESS STEEL PLATES WITH PLASMA AND TIG AUTOMATIC SYSTEM
for the production of heat exchangers from steel sheet of up to 2000mm width
with the following characteristics: reference Your drawing PUNTA20R6_L7
without Roller Conveyors and Applying Protection Film
a. The plant positions the spot-welding units and the sheets to be both spot and edge welded. The welding units are carried on pneumatic driven slides for vertical travel and on two independent motorized axes for transversal-travel. Each axis carries two torches
one for spot and transversal seam weld
and the other for longitudinal seam weld
The sheets are transferred by two couples of motorized rollers that allow sheets of considerable length to be processed
with a minimum of 1600 mm
b. An electronic device (PLC) controls the machine
governing via the program the logical sequence of the processing cycle. The PLC is connected to a touch sensitive display terminal (Touch Screen)
that allows the variable parameters for the single processes
times and positions for welding to be input and memorized in the resident programs
c. Two spot-welding and two continuous-welding units are provided each with a welding generator
made up of a torch carriage
with a special patented sheet holder
for longitudinal
transverse and spot welds
d. N° 1 SCOTCH BRITE BRUSHING UNIT to clean the bottom side of dimple jacket from the welding’s oxide
it is made the brushing unit inside of welding machine
between the torch’s crossbeam and the output rubber roller. The unit moves transversely on carriage by pinion rack system
to the vertical position controlling
a pneumatic actuator rotates the brushing unit’s arm. The brushing is made by a scotch-brite dish
e. N° 2 FRONIUS TT3000 JOB TIG generators for seam welds
f. N° 2 SBI PLASMA SPOT WELDER PSW-500 V2.1 generators for spot welds
g. Spot welding
which employ two spot-welding units
are carried out on a copper bar with cooling
h. The longitudinal weld
using two spot-welding units
is effected on a copper roller
i. The transversal weld will be done with one of two longitudinal torches 90° rotate
j. The welding devices
and accessories are carried at the side of the machine
while the respective controls and electrical components will be installed in the electric panel
k. The electrical energy supply rating is approximately 40 kW
including the welding generators
supplied at 400 Volt
3 phase
plus neutral and ground
l. No. 2 Remote Weld Monitoring Camera System
with manual control for longitudinal and transverse seam weld on the edges of the jacket sheets
m. The machine will be equipped with applications
1. No. 2 Application “Cold Wire System”
for longitudinal and transverse seam welds
2. PUNTACAM APPLICATION. CAD-CAM software that allows to create the work program from a drawing file. With this application the machine is added of an industrial computer to work with Ronzani Puntacam software
3. ARCAM APPLICATION. Added to Puntacam software and special rotating equipment
allows to make arcs and diagonal seam welds
With this application the transversal seam weld will be done with one of two longitudinal torches 180° rotate
All communication in panel will be prepared in Polish language
GENERAL DESCRIPTION
THE AUTOMATIC SYSTEM OF DIMPLE JACKET WELDING is suitable for working sheets up to 2000 mm
wide and 6000 mm long
with overall dimensions The machine has the following characteristics
The automatic system of welding executes the positioning of the torches for the spot and seam weld around the border so as to form the dimple jacket structure. The torches are fixed on a pneumatic slide with pneumatic cylinders for vertical movement and on two motorized independent pneumatic slides for transversal movement. The sheets are moved by two pairs of motorized rolls which allow the processing of sheets of remarkable length. The minimal length is of 1600 mm
The welding parameters are controlled by the PLC with a specific software that controls the operation schedule. The interface of communication between the operator and the machine consists of a touch screen control panel from which it is possible to select the position and the welding time programmable in a residential memory – copy to hard disc
There are 2 working units with 2 generators. Two units are made up by 2 slides hold-torch with special equipment pressing sheet . The TIG torches groups can be turned by 180° to permit the transversal and longitudinal seam welding
or diagonal and arc seam welding
The Plasma spot welding is done on an inferior crosspiece that supports a branch bar
with connection to ground and distribution of the protecting gas by cooling system. This crosspiece is lowered during the movement of the sheet to prevent damages on the inferior surface
The continuous welding is done on a Copper and Aluminium roller
with connection to ground
the TIG torches can be turned by 180° on the roller to permit the transversal and longitudinal seam welding
or diagonal and arc seam welding
The components of welding are assembled under the roller conveyor
The machine is provided by a monitoring system for the longitudinal and transversal welds
this system has 3 cameras fixed on its support with optical screen photosensitive and two monitors located on the control board. The position of every single torch can be adjusted manually by 3 joysticks situated on the control pulpit
Longitudinal and transversal seam welds can be realized on the edge of the sheet thanks to a monitoring system. The position of every single torch can be adjusted manually by 3 joysticks on the control pulpit
System is working under control procedure and will switched off machine in below circumstances
no power or any medium needed for process : electricity
water cooling
gas for TIG and PLASMA welding system
