The lefthand scrolling photos: Primary function parts and cells in Wuxi JACK I H Beam Assembly and Tack Welding Machine
To accomplish the sophisticated task of T/ H Beam assembling and CO2 tack welding, one set of I H Beam Assembly Machine (T Beam Assembly Machine) should contain function units of:
1) This includes: Mechanical base bed and top gantry as shown in the lefthand photos;
2) During work, a piece of oil cylinder drive rod which is assembled in the top gantry, exerts heavy downward pressure force onto T / H Beam, firmly and precisely keeping the workpiece in steady position;
3) The central working area of the I H Beam Assembly Machine is situated at base bed of the mechanical main frame.
This includes:
1) 1st step rough assembly: 2 pairs of hydraulic drive manipulators (Pulling rod box) installed at input conveyor;
2) 2nd step precise assembling group, installed at central working area.
This includes:
1) 2 sets of CO2 GMAW welding power supply, and its operating console;
2) 2 sets of wire feeding system;
3) 2 pieces of welding torch and its position precise managing group;
Installed in symmetry.
This includes:
1) A.C. inverter: For continuously controlling working speed of assembling/ stitch welding within the range of 500 ~ 6000 mm/min.;
2) PLC (Programmable Logic Controller): For flexibly and precisely controlling stitch welding seam length and interval on finished T/ H Beam;
3) Control relays and contactors.
Same as H Beam Fabrication Machine, in I H Beam Assembly Machine, assembling is implemented in the two stages of:
1) First, rough positioning and clamping of flange and web by means of hydraulic drive manipulators (The other name is pulling rod box);
2) This step is implemented simultaneously with flange and web sending in;
3) The 2 pairs of hydraulic manipulators are installed along input conveyor of the I H Beam Assembly Machine;
1) Following that, precise positioning and clamping of flange and web is realized by means of hydraulic oil cylinder drive clamping rollers;
2) These rollers are installed in the central working zone of the I H Beam Assembly Machine (T Beam Assembly Machine) in symmetry;
3) To acquired accurate assembling effect, these alignment rollers are eccentric type;
1) During assembling and CO2 intermittent welding process, the workpiece (T Beam/ H Beam) is pressed and held firmly by means of a piece of downward going pressing rod;
2) This rod is driven with an overhead oil cylinder, which are installed into top gantry of the I H Beam Assembly Machine (T Beam Assembly Machine);
4. Overall view on T Beam/ H Beam assembling in H Beam Assembly and Tack Welding Machine is shown in the 4th photo;
1. Welding mode in I H Beam Assembly and Tack Welding Machine is small to medium current CO2 gas shielded welding, in the form of intermittent tack welding;
Typical arrangement on Z15/ Z18/ Z20 I H Beam Assembly and Tack Welding Machine at customer workshop is shown in below diagram:
1 --- Mechanical main frame of the I H Beam Assembly Machine with tack welding;
2 --- Hydraulic drive manipulators (Pulling rod boxes) for carrying out the 1st stage fitting up of flange and web
3 --- Input conveyor of I H Beam and T Beam Assembly Machine;
4 --- Output conveyor of I H Beam and T Beam Assembly Machine;
5 --- Electric control system and operating panel of the I H Beam Assembly and Tack Welding Machine;
6 --- Hydraulic pump station of I H Beam and T Beam Assembly Machine;
7 --- 2 sets of CO2 GMAW power supply and its control operating consoles
This working mode is for the purpose of:
1) Starting on the I H Beam Assembly Machine everyday at beginning of work, to confirm on normal status of the machine;
2) Troubleshooting when problem happens;
3) Commissioning on the machine before trial run;
1) Stitch Welding Seam Form: You may understand that, the intermittent tack welding performed in I H Beam Assembly Machine is in the way of one segment of welding seam, followed by one segment of no welding, then followed by another segment of welding seam... in such circulation;
2) Definition: Correspondingly, during running of the I H Beam Assembly and Tack Welding Machine, finishing one segment of welding seam together with its adjacent no welding is called Single Cycle;
3) Single Cycle usually is performed after MANUAL mode, to confirm on good running of the I H T Beam Assembly Machine;
1) Definition: The continuous performing of Single Cycle is called AUTO (Short for Automatic);
2) This is the normal and major working mode of I H Beam Assembly Machine (T Beam Assembly Machine) at customer site.
1) As a kind of fully automatic equipment in I H Beam Production Line, all the working actions of I H Beam Assembly and Tack Welding Machine are manipulated by means of its operation pendant:
2) The 1st Photo: English Version and the 2nd Photo: Russian Version;
3) The function buttons on the operating panel includes but not limited to: Power On/ Off; Oil Pump Station Start/ Close; CO2 Welding Velocity Selection and Display; Working Mode Section, etc.;
1) There are 8 choices of welding speed available, based on H Beam thickness and welding technology;
2) Such selection is in the manner of switching among 8 optional output frequency section of the A.C. inverter;
3. The 1st and 2nd Photos: The real time CO2 tack welding speed is displayed in operation panel of the I H Beam Assembly Machine (T Beam Assembly Machine);
4. The 3rd Photo: Position of the 2 sets of 45° welding torch can be adjusted precisely by means of handwheel, together with oil cylinder drive slant sliding guided along precise linear rail;
1) Under both working modes of Single Cycle and AUTO, length and interval of welding seam and no-welding segment can be set up in A.C. inverter and PLC;
2) This is very useful function for customers to determine their preferred finished workpiece (T Beam/ H Beam, the 4th Photo) produced from the I H Beam Assembly Machine (T Beam Assembly Machine).
