Description

Pipe straightener

Technical field

The utility model belongs to steel pipe process equipment field, relates to a kind of pipe straightener in particular.

Background technology

In steel pipe's production processing enterprise, after the diameter of steel pipe is determined, need to carry out straightening to steel pipe, straightener is provided with several smoothing rolls, several smoothing rolls distribute in pairs, steel pipe is passed into often pair of smoothing roll centre position, smoothing roll is by motor or other drive unit driven rotary, rub with steel pipe, straightening is carried out to steel pipe, before steel pipe enters straightener, has the equipment that steel pipe is cleared up at present, prevent steel tube surface impurity or iron rust more, cause the two to damage when steel pipe and smoothing roll rub; But in friction straightening process, a large amount of metal debris is produced between steel pipe and smoothing roll, metal debris will be attached on smoothing roll surface, smoothing roll is in continuous rotary course, drive metal debris and steel pipe are rubbed, causes the two to produce larger pressure when the contact friction of metal debris place, make steel pipe and smoothing roll surface that larger scratch wearing and tearing occur, not only make tube quality decline, and affect smoothing roll service life.

Utility model content

For the deficiencies in the prior art, the utility model provides a kind ofly to be cleared up the metal debris on smoothing roll surface in time, avoids metal debris again to get back between smoothing roll and steel pipe and rubs, smoothing roll surface is lost no time, improve tube quality, extend the pipe straightener of straightening roller life simultaneously.

For achieving the above object, the utility model provides following technical scheme: a kind of pipe straightener, comprise frame and some smoothing rolls, frame is provided with the fixed head of some fixing smoothing rolls, fixed head is provided with brush, and brush is connected to smoothing roll surface, and brush is tubular, brush and fixed head are rotationally connected, and brush is connected with drive unit.

By adopting technique scheme, straightener is when carrying out straightening to steel pipe, smoothing roll and steel tube surface rub, steel tube surface produces a large amount of metal debris and is attached on smoothing roll surface, jointly rotate with smoothing roll, when smoothing roll with metal debris part rotate to brush contacts part time, metal debris will be brushed off by brush, make smoothing roll by clean surface after brush, can not kish scrap, clean surface is remained when then smoothing roll contacts with steel pipe, avoid because metal debris rubs the steel pipe that causes or smoothing roll scratch wearing and tearing between smoothing roll and steel pipe, improve the quality of steel pipe, extend the service life of smoothing roll simultaneously.

Drive brush to rotate by drive unit, namely when smoothing roll rotary motion, brush rotates simultaneously, and the metal debris on smoothing roll surface is more easily brushed off by brush, and cleaning is more clean, improves cleaning efficiency.

The utility model is set to further: fixed head is also provided with scrap guide plate, and brush is between smoothing roll and scrap guide plate.

By adopting technique scheme, metal debris on smoothing roll brushes off by brush, metal debris is fallen on scrap guide plate, metal debris accepted by scrap guide plate, and it is led, one collecting vessel is set in the end of guide plate, metal debris is fallen in collecting vessel and carries out collecting, prevent metal debris from again dropping on smoothing roll.

The utility model is set to further: the other end of the corresponding brush of guide plate is connected with dust catcher.

By adopting technique scheme, metal debris drops on scrap guide plate, to be siphoned away by the metal debris on scrap guide plate and cleans out, scrap can be prevented to be deposited in the periphery of smoothing roll, more totally by dust catcher.

The utility model is set to further: brush is wire brush.

By adopting technique scheme, wire brush toughness is better, and wire brush is wear-resistant, clean not only to smoothing roll cleaning, and brush is more of a specified duration for service life.

The utility model is set to further: smoothing roll surface is provided with carbide layers.

By adopting technique scheme, tungsten carbide stable chemical nature, and hardness is high, very wear-resisting, improves smoothing roll surface abrasion resistance, increases the service life.

Compared with prior art, the brush of the utility model pipe straightener can be cleared up the metal debris on smoothing roll surface in time, avoids metal debris again to get back between smoothing roll and steel pipe and rubs, and smoothing roll surface is lost no time, improve tube quality, extend straightening roller life simultaneously.

Detailed description of the invention

Referring to figs. 1 through Fig. 4, the embodiment of the utility model pipe straightener is described further.

A kind of pipe straightener, comprise frame 1 and some smoothing rolls 6, frame 1 is provided with the fixed head 2 of some fixing smoothing rolls 6, fixed head 2 is provided with brush 8, brush 8 is connected to smoothing roll 6 surface, and the preferred brush 8 of the present embodiment is in tubular, brush 8 and fixed head 2 are rotationally connected, brush 8 is connected with drive unit, and drive unit preferably uses motor (certain brush 8 also can select straight tabular, is fixed on fixed head 2 and does not rotate).

And scrap guide plate 7 is also provided with on fixed head 2, brush 8 is between smoothing roll 6 and scrap guide plate 7, brush 8 is all conflicted with smoothing roll 6 and scrap guide plate 7, the downward-sloping setting of preferred scrap guide plate 7, a side position near brush 8 is higher, and the highest point of scrap guide plate 7 is still lower than the axial location of brush 8, the other end of the corresponding brush 8 of scrap guide plate 7 is connected with dust catcher.

The course of work: steel pipe enters straightener, smoothing roll 6 rotates, rub with steel tube surface, straightening is carried out to steel pipe, rubbing surface produces a large amount of metal debris in the process, and metal debris is attached on smoothing roll 6 surface, smoothing roll 6 drives metal debris together to rotate, when rotating to brush 8 position, metal debris is brushed off by smoothing roll 6 surface by the brush 8 rotated by driven by motor, certainly it is worth mentioning that, the rotation direction of brush 8 is contrary with the rotation direction of smoothing roll 6 herein, the effect of such brush 8 brush metal debris reaches best, metal debris under being brushed by brush 8 drops on scrap guide plate 7, and glide along scrap guide plate 7, again siphon away by dust catcher and collect.

Brush 8 and smoothing roll 6 continuous print rotate, and metal debris constantly brushes off by brush 8, ensureing each smoothing roll 6 surface clean when contacting steel pipe, not having metal debris and rubbing between the two surface.

Preferred brush 8 is wire brush, smoothing roll 6 surface is provided with carbide layers, wire brush toughness is better, and wire brush is wear-resistant, not only to smoothing roll 6 clear up clean, and brush 8 is more of a specified duration for service life, tungsten carbide stable chemical nature, and hardness is high, very wear-resisting, improve smoothing roll 6 surface abrasion resistance, increase the service life.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
