Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
A kind of complex pipe welding and forming device control system; as shown in Figure 1; mainly comprise: control panel 1; PLC control system 2; steel band make-up machine forming angle regulating system 3; welding system 4 in the pipe; pipe external welding system 5; steel band is sent regulating system 6; driver module 7; sensor 8; and composition such as protection part etc.; its special character is: described PLC control system 2 adopts Programmable Logic Controller PLC as master controller each several part to be carried out overhead control; and by driver module respectively with make-up machine; delivery machine is connected with inside and outside welding gun weld joint tracking device; general control system is provided with starting switch; emergency stop switch; coordinate control and subsystem debugging change-over switch; for the ease of subsystem being debugged or local control setting make-up machine switch; delivery machine switch and inside and outside welding gun weld joint tracking switch are at the required various sensors of input end connection of PLC.Wherein, described steel band is sent the control of regulating system, adopts two pressure transducers, and it places down the below, two ends of sending rod respectively, and system's adjustable pressure equates the force value at two ends, thereby guarantees steadily going forward one by one of steel band.Wherein, in the process of ribbon spiral moulding, steel band delivery rate and shaping speed can keep certain relation automatically, are provided with the rotation control desk below make-up machine, can be used for the suitable adjusting of forming angle.Wherein, the method that described interior welding gun weld joint tracking device adopts the steel band edge to detect, the little welding occasion in space in can being used to manage.
The utility model is selected Siemens S-200 series of PLC for use, is the I/O except having digital quantity I/O, also has analog quantity I/O I/O.
1. the steel band control of sending
The utility model mainly is the start and stop and the rotating of control delivery machine to the control of delivery machine, but its speed real-time regulated control, thus steel band is gone forward one by one with proper speed.To the sideslip problem in the steel band delivery process, adopt two pressure transducer a, b.As shown in Figure 2, place down the below, two ends of sending rod respectively, regulate the pressure watchcase force value at two ends is equated, thereby guarantee steadily going forward one by one of steel band.
2. the adjusting of forming angle
In the process of ribbon spiral moulding, make steel band delivery rate and shaping speed keep certain relation, so just can make stable molding, produce the complex pipe of setting caliber.Designed shaped device does not need the independent supplying power of make-up machine, and it is just passable only need to regulate forming angle.Design has the rotation control desk below make-up machine of the present utility model, as shown in Figure 3, and scalable moulding angle.
