And (3) welding: the electrode plate 80 on the rotary electrode 28 starts welding the intersection point of the pressed annular rib 2 and the main rib 1. After the welded reinforcement cage moves for a certain distance, the first group of cage supporting devices 40 are lifted to support the reinforcement cage so as to prevent the reinforcement cage from deforming due to the self weight. As the reinforcement cage moves, the subsequent sets of cage supporting devices 40 are sequentially lifted.

And (3) completing welding: when the end is welded according to the specification and length of the reinforcement cage, the seam welder 200 automatically stops welding. At this point, the ring rib 2 is cut off, and the towing trolley 44 is clicked to separate the tail end of the reinforcement cage from the ring rib rotating mechanism 32.

The trolley 44 then automatically moves forward slowly for a few seconds and stops, allowing the reinforcement cage to be separated from the trolley 44.

The cage supporting device 40 is reset: after the reinforcement cage is separated from the towing trolley 44, all cage supporting devices 40 are synchronously lowered and return to the initial position.

Lifting away from the reinforcement cage: after the cage supporting device 40 is reset, the steel reinforcement cage is lifted out.

The traction trolley 44 is reset at a high speed: after the reinforcement cage is lifted away, the automatic return button is pressed, and the traction trolley 44 automatically returns to the reinforcement bar penetrating position at a high speed to perform the welding work flow of the next reinforcement cage.

After starting welding, the sizes of all sections of the ring rib 2 are automatically adjusted according to the standard of the tubular pile in the whole welding process, when a collision block of the traction trolley 44 touches a bracket (a bracket rack) switch in backward movement of the traction trolley 44, the ring rib is automatically lifted, the bracket is positioned by a pin, the use is very convenient, and the adjustment is simple. After the welding process of the whole reinforcement cage is finished, the machine is automatically stopped (the whole process does not need to be operated by people). The electrode is loosened by pulling a loosening handle of the electrode arm 66, the traction trolley 44 is inching to enable the tail end of the reinforcement cage to leave the main machine material tray frame, the 'cage releasing' knob is placed at the 'open' position, the 'cage releasing cylinder' is electrified, the trolley automatically forwards runs forwards at a low speed for 4 seconds and then stops, the reinforcement cage is separated from the trolley, and the reinforcement cage rolls away from the welding machine material rack. The trolley 44 automatically returns to the rebar penetration position at high speed according to the reverse traction point.

The ring rib rotating mechanism 32 rotates the ring rib material tray 30 through multi-stage speed reduction by the motor, and winds the ring rib on the main rib 1 with certain expansion force. The rotating speed (wire feeding speed) of the annular rib material disc 30 is matched and regulated according to the rotating speed of the main machine.

The relative position of the traction frame is corrected according to a picture and is correctly connected. And rechecking that all sizes are consistent with the drawing, threading the foundation bolts, keeping a certain margin for the threads to be higher than the nuts, pouring concrete, after solidification, accurately correcting the levelness of the welding machine again, and then fastening the foundation bolts.

When the device is installed, an electric power control line and a power supply channel are laid, and three 120 square millimeter copper core wires are used as leads from a power supply to the electric control cabinet of the seam welder 200. The zero line is 16 mm square wire. The grounding wire is a 16-square-millimeter wire, the control wire is a 1-square-millimeter copper core flexible wire, and the electric control cabinet to the main motor is a 4-square-millimeter copper core flexible wire.

The electric elements are connected according to the electric circuit diagram, and are checked strictly without errors, and the operation of each operation control button is fully familiar.

According to the specification of the pipe pile, the positioning plate and the fixed electrode wheel 82 are selected and fixed one by one. The position adjustment of the rotary electrode arm is generally as follows: when the electrode head compresses the longitudinal diameter and the circular diameter, the telescopic distance of the central mandril is 5-10 mm after the spring is compressed. The pressure of the rotary electrode 28 is adjusted by a spring seat and an adjusting nut, and can be determined according to the diameter of the welded steel bar, and the larger the diameter of the steel bar is, the larger the pressure of the spring needs to be adjusted, and the positioning bolt is fixed. And adjusting the welding current according to the diameter of the welded steel bar, and adjusting the welding time. The size of the welding current depends on the diameter of the steel bar of the welding cage body, and generally, the thicker the diameter of the steel bar is, the larger the current is needed. The pressure can be adjusted to the upper spring seat, and the locking nut locks after the adjustment.

The debugging steps are as follows:

1. the debugging can be carried out only if the installation is correct. The selective switch should be set to 'debug' during debugging.

3. The function buttons are activated in accordance with the selected function (the winding direction should be clockwise facing the copper plate, and the wire feeding direction should be in accordance with the winding direction). The direction of travel of the tractor 44 is forward away from the welding host 24 and reverse.

4. Regulating air pressure and basic parameters

(1) The total pneumatic pressure was adjusted to 0.6MPa.

(2) The pressure of each bracket is adjusted to 0.3Mpa.

5. Inputting, setting and adjusting parameters:

the distance and the length of the head end, the front end close winding, the front end, the middle section, the rear end close winding and the tail end are set. If a reinforcement cage with the length of 15 meters is machined, the total length is set to be generally not more than 15 meters, and the set length is as follows: head end spacing 20, head end length 50, front end close-wound 20, front end close-wound length 50, front end spacing 70, front end length 1400, middle section spacing 120, middle section length 11650, rear end spacing 70, rear end length 1400, rear end close-wound 20, rear end close-wound length 50, tail end spacing 20, tail end length 50. (if a reinforcement cage with 10 meters or 12 meters needs to be processed, only the length of the middle section needs to be modified.)

For example, a 10-meter steel reinforcement cage is processed, the parameters are set, idle running is automatically started, after the operation is finished, the numerical value of the position of the encoder (for example, the numerical value is 10500) is checked in the touch screen, and then the numerical value which is the same as the position of the encoder (for example, the numerical value is 10500) is input into the encoder pulse corresponding to the number of the operating meters.

Setting welding current: during trial welding, the current fine-tuning potentiometer is arranged in the middle, the strength of a welding point is observed, the welding current of a corresponding section is adjusted according to actual conditions, such as infirm welding (small current) of a section welding of 5-6 meters, and the current can be properly increased. If the steel bar is blown (the current is large), the current can be properly reduced. "C (B)

And after the primary welding process is finished, modifying a set value according to the actually measured ring diameter distance, the welding point condition and the ring diameter circle number.

The following is an electrical description of the operation of seam welder 200

The power supply is alternating current three-phase 380V,50Hz. The control power supply is direct current 24V, and the electromagnetic valve and the small relay power supply are DC24V. The machine is provided with short circuit fusing protection and motor overload protection. All data used for external adjustment are communicated with the PLC through the touch display screen to complete data setting, and current operation states and operation information of the machine are fed back to the PLC through external buttons, selection switches and sensors and are processed and output and controlled by the PLC.

Signals of the traction motor and the wire winding motor are input into the PLC through a stroke switch, a potentiometer and a button, and then the PLC outputs signals to control the frequency converter to realize the control of stop, start and rotating speed. The speed of the traction motor in the automatic welding process is controlled by a PLC according to the rotating speed of the wire winding motor and a length coefficient control frequency converter, and the rotating speed of the wire winding motor can be controlled by an R1 potentiometer. The potentiometer R2 can only be adjusted when the traction motor is started alone. The potentiometer R3 is used to fine-tune the current during automatic welding, the current increasing 6 units for every 1 volt increase, ranging from-60 to 60. The potentiometer R4 is used for adjusting current during manual welding and ranges from 0 to 999.

The wire must have good electrical conductivity. Before stretching and rolling, the wire can adopt the mechanical descaling and acid cleaning processes to remove the oxide skin and iron rust on the surface of the wire. When the forced wire drawing process is adopted, the raw material wire can not have rust. The low-oiliness lubricating powder is adopted during wire drawing. Before welding, all dirt, oil stain, oxide and rust should be removed from the drawn and rolled finished steel wire. Otherwise, the welding process can generate spark splash, desoldering, false welding or even welding failure, which affects the welding quality and seriously reduces the service life of the electrode tip. Oil stain, dirt and oxides on the electrode head need to be removed frequently, and the welding head is kept clean and smooth to ensure good conductivity. The electrode tips and the electrode arms are always kept clean, when the electrode tips are exchanged, the electrode arms and the electrode tips are polished by fine sand leather, good conductive performance is guaranteed, and the hexagon screws on the square locking blocks 68 are fastened.
