The following is the working process of the seam welder 200:
(1) feeding, penetrating main ribs, fixing ring ribs, starting welding, automatic cage removing, cage supporting device resetting, hoisting, lifting, and high-speed reset of tractor
Feeding and threading main ribs 1: the main bar 1 is placed in the feed frame 20 by a travelling crane, and the ring bar tray 30 with the ring bar 2 is arranged at a station of the ring bar rotating mechanism 32 by the travelling crane. The main bar 1 is threaded into the welding station of the seam welder 200 along the bar supporting roller 48 of the feed line frame 20 and is locked by the automatic bar locking traction disc 42.
Fixing ring rib 2: the ring rib 2 in the ring rib material disc 30 passes through the wire winding arm to the welding position of the electrode plate 80, and then the ring rib 2 is fastened or welded on the main rib 1.
Starting welding: according to the specification, the steel reinforcement cage starts to be welded, the main reinforcement 1 is locked by the automatic reinforcement locking traction disc 42 and moves linearly, the rotary electrode 28 rotates, meanwhile, the ring reinforcement 2 is automatically wound on the main reinforcement 1, and the spacing of each section of the ring reinforcement 2 can be adjusted by preset parameters.
And (3) welding: the electrode plate 80 on the rotary electrode 28 starts to weld the intersection of the held ring rib 2 and the main rib 1. After the welded reinforcement cage is moved a distance, the first set of cage-supporting means 40 is lifted up to support the reinforcement cage against deformation due to its own weight. As the reinforcement cage moves, the latter sets of cage means 40 are raised in sequence.
And (3) welding: the seam welder 200 automatically stops welding after welding to the end according to the specification and length of the reinforcement cage. At this time, the ring rib 2 can be cut off, and the traction trolley 44 is moved to enable the tail end of the reinforcement cage to leave the ring rib rotating mechanism 32.
Automatic cage removal: the "cage-out" knob is turned to the "on" position and the automatic locking bar traction disc 42 releases the main bar 1 held by the lock. The tractor 44 then automatically slows forward for a few seconds and stops, separating the reinforcement cage from the tractor 44.
Resetting the cage device 40: after the reinforcement cage is separated from the traction trolley 44, all the cage supporting devices 40 are synchronously lowered to return to the initial position.
Hanging off the reinforcement cage: after the cage supporting device 40 is reset, the reinforcement cage is lifted out.
High speed reset of the tractor 44: after the reinforcement cage is lifted off, the automatic return button is pressed, and the traction trolley 44 automatically returns to the position where the reinforcement is penetrated at high speed, so that the welding work flow of the next reinforcement cage is performed.
After starting welding, the sizes of all sections of the ring ribs 2 are automatically adjusted according to the standard of the pipe pile in the whole welding process, and when the collision block of the traction trolley 44 touches a bracket (cage supporting frame) switch in the backward movement of the traction trolley 44, the bracket is automatically lifted, and the bracket is positioned by a pin, so that the device is extremely convenient to use and simple to adjust. After the whole welding process of the reinforcement cage is finished, the automatic stop is carried out (the whole process is not operated by people). The electrode is released by pulling the release handle of the electrode arm 66, the traction trolley 44 is moved to enable the tail end of the reinforcement cage to leave the material tray frame of the main machine, the 'cage removing' knob is placed at the 'on' position, the 'cage removing cylinder' is electrified, the trolley automatically moves forwards and slowly for 4 seconds, and then the trolley stops, so that the reinforcement cage is separated from the trolley, and the reinforcement cage rolls off the material tray of the welding machine. The pulling carriage 44 automatically returns to the position of passing the reinforcing bar at high speed according to the pulling counter point.
The annular rib rotating mechanism 32 rotates the annular rib material disc 30 through multistage speed reduction by a motor, and winds the annular rib on the main rib 1 with a certain tension. The rotating speed (wire feeding speed) of the ring rib material disc 30 is matched and regulated according to the rotating speed of the host machine.
The welding transformer 46 is an overlapping iron-shell transformer, the primary winding of which is disc-shaped, and the secondary winding of which consists of two copper plates.
The welding machine has two welding modes, namely automatic welding and manual welding, and can be automatically selected according to the needs during working.
When the seam welder 200 needs to be installed, the center line and the component size of the whole machine are scribed according to the mechanical appearance and the basic diagram size, and pits, grooves and foundation bolt holes are scribed everywhere. The parts are placed to the indicated positions according to the machine basic diagram, and the level and the center height of the welding machine are corrected. The relative positions of the traction frames are corrected according to the graph and are correctly connected. And rechecking that all the dimensions are consistent with the drawing, threading the foundation bolts, keeping a certain margin higher than the nuts by threads, pouring concrete, accurately correcting the levelness of the welding machine again after solidification, and fastening the foundation bolts.
And when the electric control wire and the power supply channel are installed, three 120 square millimeter copper core wires are used as leads from the power supply to the electric control cabinet of the seam welder 200. The zero line is 16 square milli-meter line. The grounding wire is 16 square milli-meter wire, the control wire is 1 square millimeter copper core flexible wire, and the electric control cabinet to the main motor is 4 square millimeter copper core flexible wire. The copper core flexible wire is 4 square millimeters to the moment electrode and the traction motor. The electrical cabinet, the welding host 24, the transformer, etc. should be reliably grounded. The electric elements of each path are connected according to the electric circuit diagram, and the operation control buttons are fully familiar with the operation control buttons after strict inspection.
The positioning plate and the fixed electrode wheel 82 are selected according to the specification of the pipe pile and are fixed one by one. The rotating electrode arm position adjustment is typically: when the electrode head compresses the longitudinal diameter, the central ejector rod is compressed to have a telescopic distance of 5-10 mm after the ring diameter is compressed. The pressure of the rotary electrode 28 is regulated by a spring seat and an adjusting nut, and can be determined according to the diameter of the welded steel bar, and the thicker the diameter of the steel bar is, the larger the pressure of the spring is required to be regulated, and the positioning bolt is fixed. And adjusting welding current according to the diameter of the welded steel bar, and adjusting welding time. The magnitude of the welding current depends on the diameter of the steel bars of the welding cage body, and the thicker the diameter of the steel bars is, the larger the required current is. The pressure can be adjusted to go up the spring holder, lock nut locking after the alignment.
The following is the debugging step:
1. the installation is correct and can be debugged. The selection switch should be set to be "debugged" during debugging.
2. The distance between the welding signal proximity switch and the counting signal proximity switch and the signal panel screw is adjusted to be 2mm (the lamp is lighted when the proximity switch approaches the screw).
3. The function buttons are activated and the action is consistent with the selected function (wire winding direction should be clockwise rotation facing the copper plate, wire feeding direction should be consistent with wire winding direction). The forward direction of the tractor 44 is forward away from the welding host 24 and reverse.
4. Adjusting air pressure and basic parameters
(1) The pneumatic total pressure was adjusted to 0.6MPa.
(2) The pressure of each bracket is regulated to be 0.3Mpa.
5. Inputting, setting and adjusting various parameters:
the head end, the front end close-wound, the front end, the middle section, the rear end close-wound and the spacing and the length of the tail end are set. If a reinforcement cage of 15 meters is processed, the total length is set to be not more than 15 meters, and the following steps are set: head end spacing 20, head end length 50, front end tight wrap 20, front end tight wrap length 50, front end spacing 70, front end length 1400, middle section spacing 120, middle section length 11650, back end spacing 70, back end length 1400, back end tight wrap 20, back end tight wrap length 50, tip spacing 20, tip length 50. (if a reinforcement cage of 10m or 12 m is required to be processed, the length of the middle section is only required to be modified.)
For example, a reinforcement cage of 10 meters is processed, the parameters are set, the idle operation is automatically started, after the operation is finished, the numerical value of the 'encoder position' is checked in a touch screen (for example, the numerical value is 10500), and then the numerical value identical to the 'encoder position' is input in the 'encoder pulse corresponding to the number of operating meters' (for example, the numerical value is 10500).
Welding current setting: when the welding is tested, the current trimming potentiometer is arranged in the middle, the strength of the welding spot is observed, and the welding current of the corresponding section (such as infirm (small current) of 5-6 m section welding) is adjusted according to the actual situation, so that the current can be properly increased. If the steel is blown (current is large), the current can be reduced appropriately. ' s of
The welding current is divided into 5 segments in total, and the segments can be selected according to the requirement. After the welding current is determined, if the current is too large or too small at start-up, the percentage of the start-up current can be adjusted.
And after the welding process is finished, modifying the set value according to the actually measured ring diameter distance, the welding point condition and the ring diameter number of turns.
The following is an explanation of the electrical operation of the seam welder 200
The power supply is AC three-phase 380V,50Hz. The control power supply is direct current 24V, the electromagnetic valve and a miniature relay power supply DC24V. The machine is provided with a short-circuit fusing protection and a motor overload protection. All data used for external adjustment are communicated with the PLC through the touch display screen to complete data setting, and each external button, the selection switch and the sensor feed back the current operation state and each operation information of the machine to the PLC, and the PLC processes and outputs the control.
The traction motor and the wire winding motor are respectively provided with a travel switch, a potentiometer and a button, signals are input into the PLC, and the PLC outputs signals to control the frequency converter to realize control of stop, start and rotating speed. The speed of the traction motor in the automatic welding process is controlled by a PLC (programmable logic controller) according to the rotating speed of the wire winding motor and the length coefficient, 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 for trimming the current during automatic welding, and the current is increased by 6 units each time 1 volt is increased, and the range is-60 to 60. The potentiometer R4 is used for adjusting current during manual welding, and ranges from 0 to 999.
The wire used must have good electrical conductivity. Before the wire rod is stretched and rolled, the surface oxide skin and rust of the wire rod can be removed by adopting a mechanical descaling and pickling process. When the forced wire drawing process is adopted, the raw material wire cannot have rust. And low-oiliness lubricating powder is adopted during wiredrawing. The finished steel wire after stretching and rolling should be cleaned of all dirt, greasy dirt, oxide and rust before welding. Otherwise, spark splashing, unwelding and virtual welding can not even be performed during welding, so that the welding quality is affected, and the service life of the electrode tip is seriously reduced. The greasy dirt, dirt and oxide on the electrode head are removed frequently, and the welding head is kept clean and smooth so as to ensure good conductivity. The electrode tip and the electrode arm are kept clean, and when the electrode tip is exchanged, fine sand leather is used for polishing the electrode arm and the electrode tip, so that good conductivity is ensured, and a hexagon screw on the square locking block 68 is fastened.
The following is a cylinder schedule for the seam welder 200:
the machine is suitable for welding and forming the bored concrete pile reinforcement cage and the prestressed pipe pile reinforcement cage. The welding mode adopts medium-frequency inversion direct current resistance welding, and three-phase current is balanced during working, so that the pollution to a power grid is less, and the energy-saving and consumption-reducing effects are obvious. The current is precisely controlled, the splashing rate is reduced, the quality of welding spots is effectively improved, the abrasion rate of electrodes can be effectively reduced, and the service life of the electrodes is prolonged. In the whole welding process, the main rotating mechanism drives the rotating electrode to carry out rotary welding, and the reinforcement cage does not rotate. The running parameters of the equipment are all automatically controlled by electrification, and complex calculation and visual positioning are not needed. The steel reinforcement cage traction head adopts an automatic rib locking mechanism and has a one-key cage removing function, so that the production efficiency is greatly improved.
