Description
Technical field
The present invention relates to a kind of assembling-welding fixtures that is welded into cylinder, particularly a kind of sheet material that adopts steel band to wrap up and will roll up after justifying longitudinally is welded into the assembling-welding fixtures of cylinder.
Background technology
In fields such as petrochemical industry, military affairs, cylindric parts such as pipeline, tub often are welded by sheet material.It is the important procedure that this class part is made that sheet material is welded into cylinder.Existing processing method generally is by veneer reeling machine sheet material to be rolled into the opening cylinder, manually draws the opening cylinder then in and with tack welding section preliminarily forming, longitudinally carries out the welding of laser or argon arc with welding machine again, obtains cylinder part.
Adopt when having welding method now, manually draw the anchor clamps of opening cylinder in, often produce bigger piece fit-up gap, cause welding process instability and weld seam recessed owing to do not have the machinery location of circumferencial direction and close up motion.In some cases, because the effect of welding heat source makes edges of boards produce distortion and cause the variation of gap joint, even the phenomenon that can cause continuing to weld occurs.For high energy beam welding methods such as laser, the application point of thermal source is small-sized, is in the bottom of submillimeter magnitude, and welding process is very responsive to the gap, and this phenomenon is particularly outstanding.In addition, the assembling point of existing welding method is consolidated and welding is not often finished on a sleeve clamp, needs twice clamping, influences welding efficiency.
Summary of the invention
The purpose of this invention is to provide a kind of overcome above-mentioned defective roll cylindrical shell longitudinal joint soldering cramping apparatus, this soldering cramping apparatus adopts steel band wrapping, have fit-up gap machinery tighten up function, will roll up the assembling-welding fixtures that sheet material after justifying longitudinally is welded into cylinder.
The structure of the assembling-welding fixtures of welding drum of the present invention is as follows:
The side in frame left by locating hole, one end of mandrel is installed in the locating hole of frame, the other end of mandrel is installed in the locating hole of pin plate, and pin plate hangs over a side of frame, and guide rail is installed in the bottom of frame, the steel band tightening device is installed on the guide rail, can slide along guide rail, the quantity of steel band tightening device is 2-5, and clamping device is installed in the top of frame, the middle and upper part of frame has open slot, and locating piece is inserted in and is used for the location in the open slot of frame.
Above-mentioned steel band tightening device is made up of steel band, worm-and-wheel gear, tensioning train, worm-and-wheel gear is fixed on the frame, steel band is wrapped in regulating wheel and fastens, the tensioning train is driven by worm-and-wheel gear, can realize tightening up and loosening of steel band, the opening edge of opening cylinder is closed up together, and the thickness of steel band is 0.15-4.00mm.
Above-mentioned clamping device is made up of pressing plate, wedge, cylinder, and described cylinder is fixedly mounted on the frame, and the front end of cylinder is connected with wedge by hinge, and the afterbody of pressing plate is placed on the wedge, when cylinder is released, prizes the pressing plate workpiece pressing by wedge.
Can lead to inert gas in the above-mentioned mandrel, be used for the welding that back of work needs protection.
The both sides of opening cylinder of the present invention because on one side benchmark is a locating piece, on one side benchmark be gripper edge, make two opening edges that reliable location benchmark all arranged, adopt the steel band tightening system that opening edge reliably is positioned on the benchmark during location.Clamping structure has obtained enough clamping forces by the thrust that the inclined-plane of wedge has amplified cylinder.Owing to have circumferential tightening force, the present invention need not the workpiece that clamps is carried out spot welding, directly welding forming.
Compare with existing roll bending weld jig, the present invention has characteristics such as accurate positioning, clamping are reliably convenient, efficient height, especially the laser weld that is fit to sheet material cylinder type part, these anchor clamps can be realized the accurate assembling of opening cylinder and circumferentially tighten, need not the tack welding section, directly longitudinal seam is welded.Be particularly useful for rolling the laser weld of cylindrical shell.
