Abstract
The invention discloses a combined curve multi-inclination-roller steel pipe straightener, and belongs to the field of steel pipe straightening devices. The combined curve multi-inclination-roller steel pipe straightener comprising a one-direction inflection curve roller and non-inflection double-curve rollers is adopted. In the graph, a one-direction inflection curve deep concave roller is shown with number 1, a one-direction inflection curve shallow concave roller is shown with number 2, non-inflection double-curve rollers are shown with the number 3, 4, 5 and 6, and the one-direction inflection curve deep concave roller shown with number 1 is connected with a lead screw with a hydraulic protection mechanism. According to the combined curve multi-inclination-roller steel pipe straightener, the advantage of multi-inclination rollers and the advantage of two-inclination rollers are centralized, the defects of the multi-inclination rollers and the defects of the two-inclination rollers are overcome, and the advantage that a steel pipe can be straightened with the whole length is achieved.
Description
Technical field
The present invention relates to a kind of build-up curve many cross rolls pipe straightener, it belongs to steel pipe equipment for straightening field.
Background technology
Existing many cross rolls pipe straightener adopts steel pipe rotary recurvation distortion to align steel pipe, because straightener is by the restriction of structure, respectively there is the steel pipe of one section of roll spacing length cannot realize recurvation distortion by the steel tube end part aligned and afterbody, there is empty rectifying, form " gooseneck boom is curved " at steel pipe two ends, namely there is the problem cannot aligned the total length of steel pipe.And existing two cross roll pipe straighteners, because steel pipe rotary recurvation distortion is formed in smoothing roll inside, rectify although there is not sky, but exist and cannot carry out advising round problem to by aligning steel pipe.
Summary of the invention
For the problem cannot aligned the total length of steel pipe that existing many cross rolls pipe straightener exists.Present invention achieves the technological difficulties that many cross rolls pipe straightener can be aligned the total length of steel pipe.The present invention has concentrated the advantage of many cross rolls and two cross rolls, overcomes both shortcomings, has the advantage can aligned the total length of steel pipe.
To achieve these goals, the present invention takes following technical scheme:
Build-up curve many cross rolls pipe straightener is primarily of comprising the dark recessed roller of entrance unidirectional recurvation curve; entrance unidirectional recurvation curve scrobicula roller; middle without recurvation hyperbola pair roller; export without recurvation hyperbola pair roller, adjusting angle mechanism, hydraulic protecting mechanism; press screw-down; the composition such as walking beam and frame, smoothing roll and roll line are the adjustable angle of 25 ° ~ 35 °, advance in the shape of a spiral after steel pipe is nipped.
Entrance pair roller is made up of a dark recessed roller of unidirectional recurvation curve and a unidirectional recurvation curve scrobicula roller, steel pipe rotary recurvation is out of shape formed in smoothing roll inside, entrance pair roller solves respectively is had the steel pipe of a roll spacing length to there is the empty problem rectified by the steel pipe two ends of aligning.
Middle pair roller and outlet pair roller, respectively by two forming without recurvation hyperbola roller same size, are formed being aligned the press-bending of steel pipe and rule circle.
By the adjustment pressing screw-down to entrance pair roller, middle pair roller and outlet pair roller, making steel pipe form recurvation when aligning, completing and straightening operation is carried out to the total length of steel pipe.
The top roll of each group of pair roller is contained in below hydraulic protecting mechanism, when aligning has the steel pipe of box cupling head, can be lifted by top roll rapidly, play the effect of protection roll.
Accompanying drawing explanation
Shown in Fig. 1, it is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with Fig. 1 and embodiment, the present invention is described in detail further.
As shown in Figure 1, build-up curve many cross rolls pipe straightener of the present invention, by comprising the dark recessed roller 1 of entrance unidirectional recurvation curve and entrance unidirectional recurvation curve scrobicula roller 2 forms entrance pair roller, pair roller in the middle of forming without recurvation hyperbola roller 3,4, forms without recurvation hyperbola roller 5,6 and exports pair roller; Frame 8 is formed by connecting by guide pillar by entablature and sill, and it is the adjustable angle of 25 ° ~ 35 ° that the top roll of each group pair roller is arranged on ， And and roll line Shang three upper walking beams 10 by bearing block 11 respectively; Each upper walking beam 10 is arranged in hydraulic protecting mechanism 9 again respectively, and the guide pin bushing of walking beam is contained on the guide pillar of frame 8; Each hydraulic protecting mechanism is arranged on pressure leading screw governor motion 7 respectively; Each pressure leading screw governor motion 7 is arranged on the entablature of frame 8; 2nd, 6 rollers be arranged on frame 8 sill Shang ， And and roll line be the adjustable angle of 25 ° ~ 35 °; 4th roller is arranged on and presses the adjustable angle that ， And and roll line Shang leading screw governor motion 13 are 25 ° ~ 35 °, presses leading screw governor motion 13 and is arranged on the sill of frame 8; The adjustable angle describing 25 ° ~ 35 ° is above realized by adjusting angle mechanism 12.
Claims (2)
1. build-up curve many cross rolls pipe straightener, it is characterized in that: smoothing roll is by the dark recessed roller of unidirectional recurvation curve, unidirectional recurvation curve scrobicula roller and combine without recurvation hyperbola roller, the dark recessed roller of unidirectional recurvation curve and unidirectional recurvation curve scrobicula roller composition pair roller are arranged on the porch of straightener, are separately positioned on centre and the exit of straightener by the pair roller formed without recurvation hyperbola roller.
2. build-up curve many cross rolls pipe straightener according to claim 1, is characterized in that: the top roll of each group pair roller is contained in below hydraulic protecting mechanism.
