Abstract
The utility model relates to a steel pipe welding forming device, particularly an automatic compensation device of a squeeze forming roller of a steel pipe welding machine assembly, which comprises a base, a left and a right squeeze rollers, and a left and a right vertical shafts, wherein the base is respectively and transversely provided with a guiding shaft and an adjusting lead screw. The guiding shaft is provided with a left and a right movable frames which can move along an axial direction. The left and the right squeeze rollers are arranged on the left and the right movable frames by the left and the right vertical shafts. Two sides of the left and the right movable frames are provided with a left and a right cylinders which can move on the guiding shaft, and the positions of the left and the right cylinders can be adjusted by the adjusting lead screw. The left and the right cylinders are matched with the left and the right movable frames. The separation distance and the welding pressure of the two vertical shafts of a steel pipe welding machine assembly can be adjusted automatically by air pressure automatic, and the steel pipe welding machine assembly is suitable for the variance of the width of a steel strip. The weld quality of the steel pipe weld can be enhanced, the unnecessary power consumption can be reduced and the service life of the utility model can be enhanced.
Description
Technical field:
The utility model relates to the steel pipe welding fabrication equipment, and particularly a kind of pipe-welding machine group is squeezed into the forming roll autocompensation installation.
Background technology:
During with the steel band welded still pipe, topmost specification requirement is a weldquality.When adopting non-slitting steel band welded still pipe, because there is the deviation of certain size in width of steel band, the distance between two format rolls need be adjusted at any time, reaches the purpose of the steel band that is fit to different in width.Existing adjusting generally has dual mode: a kind of is that two vertical shafts all adopt leading screw to regulate distance between two vertical shafts, belongs to total man's wage adjustment joint.Another kind is that a vertical shaft adopts leading screw to regulate, and another adopts spring to regulate automatically, belongs to semi-automatic Compensation Regulation.Find that all there is defective in existing two kinds of regulative modes in actual the use.Total man's wage adjustment joint mode: because the speed of welding of steel pipe is than higher (generally reaching tens meters/minute), the reaction speed of the modulated person of giving sb. a hard time and the influence of energy are difficult to be adjusted to desirable duty.The automatic compensation way of spring: an axle adopts leading screw to regulate, another root axle adopts the spring compensation, though can reach certain compensating action, because the variation of width of steel band, will inevitably cause the skew of steel pipe axis, spring not only will provide weld force, the stress that also will provide the steel pipe journal offset to produce, the width difference of steel band, the steel shaft line deviation is also inequality, the stress that produces is also inequality, so this regulative mode still can not reach desirable duty.
Summary of the invention:
Goal of the invention of the present utility model is to overcome the deficiency of existing equipment, and provide a kind of pipe-welding machine group to be squeezed into the forming roll autocompensation installation, it adopts two cylinders to compensate automatically, make and compensate automatically in the steel pipe welding process because width of steel band changes the influence of butt welded seam quality, simultaneously, do not produce journal offset.
The technical scheme that realizes the foregoing invention purpose is: this pipe-welding machine group is squeezed into the forming roll autocompensation installation and comprises base, left side compression roller, left side vertical shaft, right compression roller, right vertical shaft, horizontal respectively on this base have the axis of guide and adjust leading screw, the left side that can move along its axis is housed on this axis of guide, right adjustable shelf, a described left side, right compression roller is by its left side, right vertical shaft is installed in this left side, on the right adjustable shelf, a described left side, right adjustable shelf both sides are equipped with the left side that can move and pass through this adjustment leading screw adjusting position respectively on this axis of guide, right cylinder, this left side, right cylinder and this left side, right adjustable shelf movingly.
In this case, the spacing that the pressure of employing gas is regulated two vertical shafts in the welded still pipe unit automatically makes the variation of the suitable width of steel band of welded still pipe unit, has improved the weldquality of welded still pipe, has reduced unnecessary power consumption.Because it is identical to preestablish the two cylinder specifications that make on the axis of guide, the pressure of two cylinders is identical, and the power of generation is identical, so can not produce the skew of steel pipe axis, the motive force that cylinder produces is the weld force that pure welding needs.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The embodiment that provides below in conjunction with accompanying drawing describes the utility model in detail.
The utility model is by base 1, the axis of guide 2, adjust leading screw 3, left side cylinder 4, left side adjustable shelf 5, left side vertical shaft 6, left side compression roller 7, right compression roller 9, right vertical shaft 10, right adjustable shelf 11, right cylinder 12 constitutes, horizontal respectively on this base 1 have the axis of guide 2 and adjust leading screw 3, on this axis of guide 2 left side that can move along its axis is housed, right adjustable shelf 5 and 11, this left side, right compression roller 7 and 9 is by its left side, right vertical shaft 6 and 10 is installed in this left side, on the right adjustable shelf 5 and 11, this left side, right adjustable shelf 5 and 11 both sides are equipped with the left side that can move and pass through these adjustment leading screw 3 adjusting positions respectively on this axis of guide 2, right cylinder 4 and 12, the effect of this adjustment leading screw 3 is to adjust a left side, right cylinder 4 and 12 position, limit a left side, right vertical shaft 6 and 10 ultimate range, simultaneously, make a left side, right vertical shaft 6 and 10 is in the automatic compensation range.When width of steel band narrowed down, because the effect of cylinder, left and right compression roller 7 and 9 moved to the center automatically simultaneously, when steel band broadened, it is big that steel pipe 8 diameters become, and left and right compression roller 7 and 9 is forced to both sides and moves, promote left and right cylinder 4 and 12 returns, realize automatic Compensation Regulation.
Adjust the pressure of gas in the cylinder, just can adjust the motive force of cylinder very easily, just adjusted the pressure of compression roller, promptly adjusted the welding extruding force soldered steel pipe to adjustable shelf.
Cylinder in the utility model also can be substituted by the hydraulic cylinder of same function.
