UBZ12 U Beam BOX Beam Assembly And Tack Welding Machine

A. Usage and Working Steps of UBZ12 U Beam BOX Beam Assembly Machine:

1. Work Station: The second critical step in BOX Beam Production Line is first U Beam then BOX Beam assembly and tack welding. The UBZ12 model machine is for this attaining purpose. It is the 2^nd set of critical BOX Beam Production Equipment;

2. Function and Finished Workpiece: The assembled internal baffle plates, delivered from GZ12/ GZ15 BOX Beam Baffle Plate Assembly and Welding Machine, will be sent to this UBZ12 model machine. Then, baffle plates will be fit up together with long narrow plates as side plates, producing finished U Beam and BOX Beam;

3. Illustration on Major Steps of UBZ12 U Beam BOX Beam Assembly and Tack Welding Machine:

1) Step 1: 4 pieces of internal baffles plates to be fit up in erected position, being assembled onto end plate with regular interval: (Fig.1)

2) Step 2: 2 pieces of side plates to be assembled, connected with the 4 pieces of internal baffle plates. Thus come into being assembled U Beam: (Fig.2)

3) Step 3: Cover plate to be assembled onto U Beam: (Fig.3)

4) Step 4: The finished assembled and tack welded BOX Beam: (Fig.4)

5) The finished assembled and tack welded BOX Beam from Wuxi JACK UBZ12 U Beam BOX Beam Assembly Machine: (Fig.5)

B. Operating Principle of UBZ12 U Beam BOX Beam Assembly and Tack Welding Machine:

This machine works in the form of: Workpiece in stationary, while function unit moves in adjustable working speed:

1. Appearance of UBZ12 machine see attached picture and below:

Wuxi JACK UBZ12 finished installation at customer facility: (Fig.6)

2. Workpiece Placement: During work, raw materials (Plates and Internal Baffles) are put onto machine worktable, which is equipped with segments of conveyors;

3. Operating Movement: The moving gantry of UBZ12 machine moves along the rail. Which means, operating mechanism of UBZ12 machine also moves in working speed;

4. Movement with Assembly: At the same time with gantry moving forward, the downward stroke cylinder and sideward stroke cylinders which are installed on the gantry, firmly press side plates and cover plate of the U Beam BOX Beam tightly into shape, and implement tack welding on the assembled sections simultaneously:

5. Assembly on Integral BOX Beam: By way of gantry movement, the entire length of the workpiece (U Beam BOX Beam) is pressed and tack welded. The finished WIP (Work in process) of assembled BOX Beam is sent away from this BOX Beam Production Equipment, and delivered to the next step of XQ12 back welding machine, and XD12/XD15 electroslag welding machine;

6. Operating Steps in UBZ12 U Beam BOX Beam Assembly and Tack Welding Machine:

The illustration on the process flow of assembly and tack welding happened in this machine see attached the previous segment:

1) First, have tack welding on internal baffles;

2) Second, assemble 2 pieces of web (Side plates) onto U Beam;

3) Third, have manual welding on internal baffles;

4) Fourth and finally, the last piece of flange (Cover plate) assembled and tack welded onto BOX Beam.

C. Structure of UBZ12 U Beam BOX Beam Assembly Machine:

1. Main Units of U Beam BOX Beam Assembly and Tack Welding Machine:

The UBZ12 is mainly composed of:

1) Motor drive moving gantry, assembled with central function units;

2) Stationary worktable and its conveyor;

3) Hydraulic system;

4) Electric control and operating system;

2. Central Unit: Of which, the motor drive moving gantry is the main and core unit of the machine. All the pressing units (Oil cylinders) for performing tack weld are installed here. Movement of the gantry is driven with two sets of motor transmitted with worm gear reducer;

3. Quality Assurance of UBZ12 U Beam BOX Beam Assembly Machine:

1) Rails of this UBZ12 machine is of 38kg/m heavy duty type, guaranteeing stable movement of gantry beam for assembly operation;

2) Meanwhile, there is high strength pulling rod connected between the two parallel rails, avoiding the phenomenon of outer splay of the rails under the effect of left and right oil cylinders, thus in turn guaranteeing U Beam BOX Beam assembly quality;

3) The conveyor is driven with cycloidal gear reducer, and transmitted with chain and sprocket. It is for the task of assisting assembly and tack welding process, as well as sending the workpiece (U Beam BOX Beam) to the next station at the completion of assembly and tack welding operation.
