1) This is the largest model of ZHJ series conventional Integrated function Automatic H Beam Welding Machine;
2) Max. Workpiece Size: ZHJ8020 Integral Function H Beam Welding Machine has manufacturing capability of welding H Beam with web height up to 2,000 mm, in the form of symmetric joint between web and flanges. Please check attached picture and below sketch:
2. Welding Mode: For producing such big size of workpiece, the welding mode in ZHJ8020 Integral function H Beam Fabrication Machine is SAW (Submerged arc welding).
Besides size range denoted at end of this section, another requirement on finished product from ZHJ series Integrated function H Beam Welding Machine is:
As one of the preparatory tasks of operating on ZHJ series Vertical H Beam Welder (Vertical Integrated function H Beam Welding Machine), please make sure specifications of welding H Beam conforms to below rule of thumb on relationship between flange thickness and width that can be straightened with ZHJ series H Beam Assembly Welding Straightening Machine:
Flange Thickness T(mm) | 6~20 | 20~25 | 25~32 | 32~40 |
Flange Width B(mm) | 200~800 | 450~800 | 600~800 | 700~800 |
1) The attached picture shows mechanical main body of a set of ZHJ8020 Integral function H Beam Welding Machine:
2) Such big height Vertical H Beam Welder is assembled into shape from a vertical gantry and a solid base, with assembling unit, welding torches and straightening rollers fit in sequence;
3) In practical use, there also will be input and output conveyors equipped with the SAW H Beam Fabrication Machine;
1) Workpiece goes into this Pull Through H Beam Welder (3 in 1 H Beam Welding Machine) from rear side of the mechanical main body and comes out from its front side (Viewed from attached picture);
2) This is also working sequence of assembling/ welding /straightening arrangement fulfilled in central function zone of the 3 in 1 H Beam Assembly Welding Straightening Machine;
1) In conventional H Beam Assembly Machine, both assembling and tack welding (Usually CO2) are performed on workpiece H Beam;
2) Comparatively, in ZHJ series SAW H Beam Fabrication Machine, the workpiece is assembled and then submerged arc welded at the same time;
3) In other words, only the final welding of SAW (Submerged Arc Welding) is implemented in ZHJ series Integrated Function Automatic H Beam Welding Machine: The original CO2 tack welding is removed because of unnecessary in this combined function of 3 in 1 H Beam Assembly Welding Straightening Machine;
1) This section serves as “Arm” of the 3 in 1 H Beam Assembly Welding Straightening Machine;
2) It includes three segments of input and output conveyor each (totally 10m length each);
3) One piece of motor drive segment and two pieces of idling segments are included into each of the input and output conveyors;
4) For safety purpose, the transmission unit of the Pull Through H Beam Welder input and output conveyors are covered;
1) Task: This unit supplies the “Blood”, or power source to assembling and straightening units of the SAW H Beam Fabrication Machine;
2) Where Used: The assembling unit of manipulators, alignment rollers, and straightening unit of straightening roller are all driven with hydraulic system;
1) Role: This unit is “Brain” of ZHJ series Integrated function Automatic H Beam Welding Machine;
2) Its core elements are A.C. inverter and control relays, controlling motion logic and working speed of the Integrated function H Beam Welding Machine respectively;
7) Contontinuous Improvement: With years of communication and feedback from customers around the globe, from developing stage DFMEA/ PFMEA/ Process Flow/ Control Plan, to mass production stage IQA/ SWS/Periodical Audit, to customer service ECA/Root Cause/PCA, Wuxi JACK has ZHJ series and PHJ series Integral function H Beam Welding Machine in continuous improvement all along, in its design, manufacture and service.
