The specific embodiment
Describe performance of the present invention in detail below in conjunction with annex, but they do not constitute limitation of the invention, only do for example.Simultaneously by illustrating that advantage of the present invention will become clear more and understanding easily.
Consult accompanying drawing as can be known: steel welding seam edge-excavating device of the present invention, it comprises uncoiler 1, pinch roll 2 successively, be used for welding machine 3 that back row band steel 6 and the band steel 7 that moves ahead are welded together, digs the limit and cuts 4, jockey pulley is at welding machine 3 with dig the limit and weld seam detection machine 8 is arranged between cutting 4.Welding machine 3 and to dig the distance of cutting between 4 on the limit be 120cm, weld seam detection machine 8 and to dig the distance of cutting between 4 on the limit be 50cm (as shown in Figure 1 and Figure 2).
The control method of steel welding seam edge-excavating device is characterized in that its negative following steps of drawing together:
The 01st step: weld seam selects to dig the limit, and welding machine 3 beginnings are in the back row band steel 6 and the welding between the band steel 7 that moves ahead, and digs the limit and cuts 4 playback and prepare butt welded seams and dig the limit;
The 02nd step: the welding machine playback is finished in welding;
The 03rd step: uncoiler is built and is opened; If not, returned for the 2nd step;
The 04th step: tension force reaches setting value;
The 05th step: unit was with operation forward in 30m/ minute; If not, returned for the 4th step;
The 06th step: the weld seam detection signal is 1;
The 07th step: unit continues positioning trip 50CM forward; If not, returned for the 6th step;
The 08th step: 50CM finishes the location;
The 9th step: dig the limit and cut the limit program of digging of carrying out; If not, returned for the 8th step;
The 010th step: dig the limit and finish, circulate next time; Returned for the 1st step (as shown in Figure 3).
Be retracted into a mouthful segment process (as Fig. 1) from connecting, can see be with steel and back row band steel by the welding machine welding in advance after, weld seam is at the center line of welding machine, distance is dug cutting edge center, limit 120CM.For guaranteeing that the weld seam accurate in locating is to digging cutting edge center, limit, do not build tension force (because moving weld seam to uncertain position in case build a uncoiler counter-rotating meeting) between uncoiler and the jockey pulley and directly start finder, uncoiler, pinch roll, jockey pulley move 120CM together forward.The weld seam accurate localization is cut the center to digging the limit like this.But when weld seam navigated to and digs the limit and cut, owing to do not build tension band steel injustice, strip edge portion can not enter into very smoothly dug cutting edge district, limit.Want to enter into the cutting edge district smoothly, it is flat to set up tension force retainer belt molten steel earlier, and the band steel just enters the cutting edge district easily in the situation that keeps tension force.Produced a new problem after setting up tension force earlier: weld seam is uncoiled machine and moves one section uncertain place, front (as Fig. 2) to, and weld seam can't accurately navigate to and dig the limit and cut the place.For this reason, the 50cm place adds a weld seam detection instrument before digging the limit and cutting, and after the punching that detects weld seam, moves the 50cm weld seam more forward and just can accurately arrive and dig the limit and cut center line during the finder operation.
So at welding machine and dig the limit and increase a weld seam detection instrument between cutting, again by revising the PLC program, allow welding machine finish welding back uncoiler and set up tension force automatically, guarantee that the band steel is straight, allow unit operation again, the weld seam detection instrument detects to begin after the weld seam punching weld seam accurately navigated to and digs the limit and cut, strip edge is along straight entering into digging the photoelectric tube detecting area of cutting on the limit like this, after photoelectric tube detects the strip edge edge, dig the limit and cut that just stopping and begin punching press automatically digs the limit to the walking action of unit center line, the band steel just can not be extruded distortion.
