The GZ12/ GZ15 models machines are for assembling and tack welding this half finished workpiece, from raw materials of cut plate. It is the first critical step in BOX Beam production;
1) Design sketch on baffle plate: (Fig.1)
2) Photo on finished baffle plate from Wuxi JACK GZ12 model machine: (Fig.2)
2. Specifications of Internal Baffle from BOX Beam Baffle Plate Assembly Machine:
The baffle plates produced with this machine is for manufacturing BOX Beam of:

B. Technical Specialty of GZ12/ GZ15 BOX Beam Baffle Plate Assembly and Welding Machine:
1. Equipment Nature: As first stage BOX Beam Assembly Machine, this rough assembly machine is specifically designed for assembly and welding of internal baffles, the WIP (Work in process) of BOX Beam. In other words, it is a dedicated equipment for BOX Beam production, not universal machine;
2. Appearance of BOX Beam Internal Baffle Assembly Machine:
1) What Like: Judging from its appearance in attached and below photo, this machine is a motor drive automatic operating Welding Fixture:
2) Photos on Wuxi JACK GZ12 model machine being in test before delivery: (Fig.3)
3) Shown in the above photo, there is positioning unit on its work table, which performs assembly operation on internal baffle plate. This unit can be moved and adjusted along work table based on different sizes of baffle plate, making sure precise positioning and assembly, avoiding welding deformation happen;
3. Operation Step in BOX Beam Baffle Plate Assembly Machine:
1) To start the assembly and tack welding work, first place the raw material of cut plates onto work table of machine;
2) After positioning of the cut plates, manually press and secure it tightly. In this equipment, the press and hold on of workpiece is by means of air cylinder. This is the first step of assembling;
3) The second step of welding on the positioned cut plates into internal baffle is performed following that, in the manner of manual welding;
4) To adjust angular position of workpiece cut plate, the machine work table can be rotated within the range of ±180° in constant speed, which is driven with motor reducer. This leads workpiece into continuous revolve correspondingly, making sure it to be positioned at the best angular position, for carrying out assembly and welding operation.
C. Working Principle of GZ12/ GZ15 BOX Beam Baffle Plate Assembly Machine:
1. In essence, this machine is a simplified fixture type Welding Positioner, for fulfilling internal baffle assembly and welding to some extent. This can also be observed from its appearance;
2. Operating Way: In this respect, the working principle of this machine is to locate and clamp workpiece first, then put it into the optimum position for operation (welding) by way of work table turning;
3. Central Function Element of Baffle Plate BOX Beam Assembly Machine:
1) Angular Position Control: For this reason, turning (tilting, or revolving) of the machine work table and hence cut plate is of vital importance for normal work;
2) Drive and Transmission: The infinite turning of work table is driven with electromagnetic braking motor, and transmitted with worm gear reducer, which guarantees on precise location of work table and cut plate at any desired target position, together with self-lock function;
3) Revolve Operation: The work table turning operation is manipulated with foot pedal switch, releasing hands of operator for alternative jobs at the same time when working with this GZ series machine;
4. Double Sides Welding: The work table revolves within the scope of ±180°. This is for the ease of both sides welding on workpiece cut plate: Upon completion of one side welding, just rotate the work table to the opposing side, and carry out welding on the opposing side of the workpiece. Here the welding operation on internal baffle plate is accomplished with manual job;
5. Cut Plate Fixture: Pressing of the workpiece is adopted with pneumatic drive. During work, the piston rod of the air cylinder props up, pushing the hold down rod pressing against workpiece tightly, for the next step of welding step.
D. Structure and Main Units of GZ12/ GZ15 BOX Beam Internal Baffle Assembly Machine:
1. What Look Like: As can be checked from attached photos of the machine, this equipment has the structure of stationary welding fixture type. It is secured into workshop floor with anchor bolts:
Installing Wuxi JACK GZ15 model machine into workshop floor: (Fig.4)
2. The fundamental unit of this machine is its revolving work table. Its frame structure gives the machine the highest degree of stability, making it put on the ground and work stably;
3. The supporting units of this machine include:
1) Work table revolving driving motor (braking type) and its worm gear motor reducer;
2) Pneumatic system for holding workpiece;
3) Positioning unit on the work table;
4) Electric control board and foot pedal switch.
