The working process of the 200 roll welding machine is described below:

• ①Insertion and threading of the main bar → ②Fixing of the ring bar → ③Start of welding → ④Welding process → ⑤Completion of welding → ⑥Automatic cage release → ⑦Return of the cage support device → ⑧Lifting of the reinforcement cage → ⑨Return of the carriage at high speed

Insertion and threading of the main bar 1: The main bar 1 is inserted into the inlet frame 20 by means of a crane, and the ring reinforcement shell 30 with the ring bar 2 is loaded onto the ring reinforcement rotating device 32 with the crane. The main rod 1 is threaded into the roller welding machine 200 along the infeed frame 20 and locked by the automatic locking rod pull cup 42 .

Attaching the Ring Bar 2: Pass the Ring Bar 2 in the Ring Rail Material Tray 30 through the Wire Wrap Arm to the welding position of the Electrode Plate 80, and then attach or weld the Ring Bar 2 to the Main Bar 1.

Start of welding: Welding of the reinforcement cage starts according to the specifications. The main rod 1 is arrested by the automatic pull pulley 42 and moved in a straight line that rotates The leading electrode 28 rotates and at the same time the ring rod 2 is automatically wound around the main rod 1. The distance between the segments of the ring bar 2 can be adjusted by preset parameters.

Welding process: The electrode plate 80 on the rotating electrode 28 starts welding the intersection of the pressed ring bar 2 and the main bar 1. After the welded reinforcement cage has traveled a certain distance, the first group of stirrup cage devices 40 are raised to hold the reinforcement cage and to prevent it from being deformed by its own weight. As the cage continues to move, subsequent stirrup cage devices 40 are raised in turn.

Completion of Welding: When the end of the rebar cage has been welded according to the specification and the length of the rebar cage, the 200 roller welding machine will automatically finish the weld. At this point, the ring bar 2 can be severed and the pull carriage 44 tapped to remove the end of the reinforcement cage from the ring bar rotating mechanism 32 .

Automatic Cage Release: Turn the "release" knob to the "on" position and the automatic locking rod pull cup 42 will release the locked main rod 1. The trolley 44 then automatically advances at a slow speed for a few seconds and then stops, thereby separating the cage from the trolley 44.

Reset of the cage support device 40: After the separation of the reinforcement cage from the traction carriage 44, all cage support devices 40 are lowered at the same time and return to their original position.

Lifting off the reinforcement cage: After resetting the cage support device 40, the reinforcement cage is lifted off.

High-speed retraction carriage: After raising the rebar, press the “auto return” button. The 44 carriage will automatically return to the place where the rebar was placed at high speed and weld the next rebar.

After the start of the welding process, the size of each section of the ring bar 2 is automatically adjusted to the standards of the tube stack throughout the welding process. During the rearward movement of the tractor 44, the tractor 44 is automatically raised when the tapping block touches the boom (boom frame) switch, which is positioned by pins and is extremely convenient to operate and easy to adjust. After the completion of the whole welding process of the reinforcement cage, the machine will stop automatically (the whole process does not require human operation). Squeeze the electrode arm release handle 66 to release the electrode, tap the pull carriage 44 to deploy the end of the rebar cage out of the main frame material cup frame, set the cage off knob to the on position, " Decage Cylinder” when the power is turned on, the carriage will automatically advance at a slow speed for 4 seconds and then stop, causing the rebar to separate from the carriage and roll the rebar away from the frame of the welding machine. Press the pull counterpoint, the pull carriage 44 will automatically return to the position where the steel bars are worn at high speed.

The ring-bar rotating mechanism 32 rotates the ring-bar material plate 30 by multi-stage reduction of the electric motor winding the ring-bar around the main bar 1 with a certain force. The rotation speed (wire feed speed) of the ring tension disk 30 is matched to the rotation speed of the main machine.

The welding transformer 46 is a lapped iron-casing transformer with a disc-shaped primary winding and a secondary winding consisting of two copper plates.

The welding machine has two welding modes: automatic welding and manual welding, which can be selected according to work needs.

When you need to install the 200 roll welding machine, refer to the mechanical shape and size of the foundation drawing, draw the center line of the whole machine and the size of the components, open the pits and slots and the holes for the ground bolts at each place . Place the components in the specified position according to the machine foundation drawing and correct the leveling and center height of the welder. Correct the relative position of the tractor frame according to the drawing and connect it correctly. And check all dimensions should be in accordance with the drawings, screw to the bottom, the thread should be higher than the nut, to leave a certain margin, fill with concrete, after solidification, recalibrate the welding machine level accurately, and then tighten the ground screws everywhere.

Simultaneously with the installation, the power control lines are laid, as well as the power supply ducts. The lines from the power supply to the electrical control cabinet of the roll welding machine 200 consist of three 120 square mm copper core wires. The zero wire is a 16mm wire. The ground wire is 16mm square wire, the control wire is 1mm square copper wire and the electrical panel to the main motor is 4mm square copper wire. A flexible wire with a 4 mm copper core is placed between the torque electrode and the traction motor. The electrical cabinet, main welding frame 24, transformer, etc. should be reliably grounded. Connect the electrical components of each circuit according to the electrical wiring diagram, checking carefully that they are correct and becoming familiar with each control button.

According to the specifications of the tubular pile, choose the positioning plate and fixed electrode wheel 82, and fixed one by one. The rotating electrode arm position adjustment is generally: when the electrode head is pressed against the longitudinal diameter, the ring diameter makes the spring compressed according to the central upper bar telescopic distance of 5-10mm. The pressure of the rotating electrode 28 is adjusted by the spring seat and adjustment nut, can be based on the size of the diameter of the welded rebar, typically the thicker the diameter of the rebar, the larger the spring pressure can be adjusted and fixed locating bolts. The welding current is adjusted according to the diameter of the rods, and the welding time is adjusted. The level of the welding current depends on the diameter of the cage bars to be welded. Typically, the larger the diameter of the rods, the higher the current required. The pressure can be adjusted on the spring seat and secured with the lock nut after adjustment.

For example, to process a 10 meter rebar, set the above parameters, automatically start the air lifter, then check the value of “Transducer Position” on the touch screen when the process is finished (example: value 10500) , and then enter the same value as the "encoder position" in the "meters running according to encoder pulse" (example: value 10500).

Welding current adjustment: When trying to weld, first put the current trimming potentiometer in the middle, observe the strength of the weld, and adjust the welding current of the corresponding section according to the actual situation [if the 5m-6m section is not welded tightly (small current), the current can be increased accordingly. If the rebar is burnt (high current), the current can be reduced.]

The welding current is divided into 5 segments, which can be selected according to your needs. Once the welding current has been determined, the starting current percentage can be adjusted if the starting current is too high or too low.

At the end of a welding process, the set values are changed according to the actually measured ring pitch, the condition of the weld and the number of ring turns.

Below is the electrical manual for the 200 roll sealer

The power supply is AC three-phase 380V, 50Hz. The power supply of the controller is DC 24V, the power supply of the solenoid valve and small relay is DC24V. The machine is equipped with short-circuit protection and motor overload protection. All data for external adjustment is set through the touch screen and PLC communication. The external buttons, selector switches and sensors pass on the current operating status of the machine and the operating information to the PLC, which processes and outputs the controller.

The traction motor and wire winding motor are fed into the PLC using traction switches, potentiometers and push buttons, which then outputs signals to control the frequency converter for stopping, starting and speed control. The speed of the pulling motor during the automatic welding process is controlled by the PLC according to the "length factor" of the winding motor, while the speed of the winding motor can be controlled by the potentiometer R1. Potentiometer R2 can only be adjusted when the traction motor is started separately. Potentiometer R3 is used to fine tune the current in automatic welding, increasing the current by 6 units for every 1 volt increase, in the range -60 to 60. Potentiometer R4 is used to adjust the current in manual welding, in the range 0 to 999.

The wire used must have good electrical conductivity. Wire may be mechanically descaled and pickled prior to drawing and rolling to remove oxidation and rust from the wire surface. When using the forced drawing process, the raw wire must not show any rust. A low-oil lubricating powder is used in wire drawing. After drawing and rolling, the finished wire should be cleaned of dirt, oil, oxides and rust before welding. Otherwise, the welding will produce sparks, desoldering, incorrect welding or even not be welded, affecting the quality of the welding, and at the same time will seriously reduce the life of the electrode head. Always remove oil, dirt and oxides from the electrode head to keep the head clean and shiny and to ensure good electrical conductivity. Always keep the electrode head and electrode arm clean between the electrode heads, when changing the electrode head, polish the electrode arm and electrode head with a fine layer of sand to ensure good electrical conductivity, and tighten the hexagonal screws on the square locking block 68.
