Abstract
The present invention relates to one kind of multiple-roll composite curve type steel pipe straightening machine for finishing and straightening steel pipe in the whole length. The technological scheme of the present invention is that the multiple-roll composite curve type steel pipe straightening machine includes roll pairs comprising hyperbolic curve rolls without reverse bending in the entrance and exit of the machine, roll pairs comprising convex curve roll with long reverse bending and concave curve roll with long reverse bending in the middle part of the machine, and fast opening mechanism over the roll pairs. The present invention has the advantages of whole length steel pipe straightening, steel pipe end protecting, etc.
Description
Technical field
The present invention relates to a kind of a plurality of roller build-up curve roller type steel tube flattening machine, it belongs to a kind of steel pipe finishing equipment for straightening.
Background technology
The present steel pipe multi-roll straightening machine that uses in the steel pipe aligning, the recurvation that steel pipe is subjected to form between up-down rollers in the spiral revolution is out of shape, and reaches the purpose of steel pipe finishing aligning.Because roll spacing is bigger, form recurvation, must there be enough sections of nipping to form recurvation, so this pipe straightener can be aligned the pipe shaft of steel pipe, but can't align the end and the afterbody of steel pipe; Exist the shortcoming that to align whole length steel pipe.
Summary of the invention
The objective of the invention is to solve existing multiple roll pipe straightener exists can't be to the technological difficulties of whole length steel pipe aligning, and provide a kind of a plurality of roller build-up curve roller type steel tube flattening machine that can align whole length steel pipe.
The present invention for the technical scheme that solves above-mentioned technological difficulties and adopt is: a plurality of roller build-up curve roller type steel tube flattening machine, it comprises no recurvation hyperbolic curve roller, wherein: it also comprises a protruding roller of long recurvation curve, recessed roller of long recurvation curve and fast opening mechanism, and the pair roller of being made up of no recurvation hyperbolic curve roller is arranged on the gateway of pipe straightener and locates; By the protruding roller of long recurvation curve of recurvation distortion with grow the centre that pair roller that the recessed roller of recurvation curve forms is arranged on pipe straightener, each organize pair roller be contained in fast opening mechanism below.
Because pair roller in the middle of the present invention increases at multi-roll straightening machine or in to roller straightener, and middle pair roller roller curve is selected the long recurvation curve that can carry out the recurvation distortion between roll gap to roundwood for use, the roller curve of gateway is selected no recurvation hyperbolic curve for use, can guarantee like this roundwood nip smoothly and the aligning process in the whipping of steel pipe when advancing, simultaneously because depressing adjustment and can carry out the recurvation bending between roller to pipe shaft; The roller curve of middle pair roller is selected long recurvation curve for use, and steel pipe just can carry out recurvation between roll gap like this, and the pipe end that can't form distortion to the front and back roller is aligned.For overcoming thin-wall steel tube or the thickening pipe end is nipped and dished out in the process, smoothing roll influence the pipe end ovality to the flattening of pipe end, and depressing that each roller is increased the fast opening mechanism of hydraulic pressure in the guiding mechanism, open automatically when pipe end enters or dishes out, and abdicates pipe end.
Because the present invention has adopted the technical scheme of said structure form, can not only align the pipe shaft of steel pipe, and can also align the end and the afterbody of steel pipe, has realized whole length steel pipe is aligned; In straightener, increase quick-opening device, protected steel tube end part not to be crushed.Therefore, compare with background technology, the present invention has and can align and protect advantages such as steel tube end part to whole length steel pipe.The present invention is adapted to the combination of multiple straightening process, is applicable to the aligning of steel pipe and bar.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, three pair roller build-up curve roll shape pipe straighteners in the present embodiment, it comprises frame that is made of upper spider 7, lower bearing bracket 6 and guide pillar 5 and two pairs of pair rollers 4,8 of being made up of no recurvation hyperbolic curve roller, guide pillar 5 is located between upper spider 7 and the lower bearing bracket 6, wherein: it also comprises the protruding roller of long recurvation curve 2, a recessed roller 3 of long recurvation curve and the fast opening mechanism 1 of three covers; First pair of pair roller of being made up of no recurvation hyperbolic curve roller 4 is located at the porch of frame, its lower roll is contained on the lower bearing bracket 6, top roll be contained in first cover fast opening mechanism following and with roll-to-roll layout down, axes intersect becomes 25～35 ° adjustable angle, and the fast opening mechanism of first cover is contained on the upper spider 7 and its fairlead is contained on the guide pillar 5; By the protruding roller 2 of long recurvation curve of recurvation distortion with grow the recessed roller 3 of recurvation curve and form the centre that pair roller that axes intersect becomes 25～35 ° of adjustable angles is arranged on pipe straightener, this pair roller is positioned at the back of the pair roller of being made up of no recurvation hyperbolic curve roller 4, the recessed roller 3 of long recurvation curve is contained in the centre of lower bearing bracket 6, the protruding roller 2 of long recurvation curve be contained in the fast opening mechanism of second cover below, centre and its fairlead that the fast opening mechanism of second cover is contained in upper spider 7 are contained on the guide pillar 5; Second pair of pair roller of being made up of no recurvation hyperbolic curve roller 8 is located at the exit of frame and is positioned at the protruding roller 2 of the long recurvation curve that is out of shape by recurvation and the back of the pair roller that the recessed roller 3 of long recurvation curve is formed, its lower roll is contained on the lower bearing bracket 6, top roll be contained in the 3rd cover fast opening mechanism following and with roll-to-roll layout down, axes intersect becomes 25～35 ° of adjustable angles, and the fast opening mechanism of the 3rd cover is contained on the upper spider 7 and its fairlead is contained on the guide pillar 5.
