Abstract

The utility model provides a straightening machine that can straightens the guard rail fast and with high efficiency. The utility model comprises a motor, a transmission unit, a roller and a stander. The external circumference surface of the roller is provided with ring groove whose cross section is arc shaped. The roller is connected with the roller axis that is arranged on the stander; four or more than four rollers are arranged into up and down two lines with each roller tangent with one straight line; the transmission unit is connected with the part of the roller axie. The linear velocities at the contact point of the roller on the roller axis that is connected with the transmission device is the same.

Description

The fence upright straightener
Technical field
The utility model relates to a kind of steel tube straightening machine, particularly repairs highway Φ 140, and Φ 114 corrugated beam barrier columns can be repaired into original shape with hitting column distortion, bending, to reach the purpose of reusing.
Background technology
Along with developing rapidly of China Higher level highway cause, driven the expansion in highway barrier field, the problem of also having brought guardrail how to keep in repair simultaneously mainly is at guardrail board of being hit distortion and fence upright.Effective reparation of guardrail board can be repaired the machine shaping by special guardrail board, and the rectification reparation of fence upright does not have professional equipment at present, generally is by following two kinds of methods:
According to lever principle, pull straight or big the hammering by artificial, crowbar.This method efficient is low, of poor quality, and labour intensity is big, and it is not attractive in appearance to be repaired surface of the work yet.
Come alignment by acupression, in entire work process, want workpiece loading and unloading twice, first alignment, full circle again.The workpiece that is about to need to repair is placed on the horizontal table, applies a static pressure vertically downward at the place, peak of its distortion, makes its sweep progressively straight.But,, cause efficient low, and the alignment quality is not good so need the operation of repeated multiple times because steel pipe has springback capacity in alignment process.
Summary of the invention
The invention provides a kind of straightener of can be fast, efficiently fence upright being carried out alignment.
This fence upright straightener, comprise motor, transmission mechanism, roll, frame, it is the annular groove of arc that cross section is arranged on the outer circumference surface of roll, roll is connected on the roll mandrel, roll mandrel is arranged on the frame: four or more roll divides two rows to arrange that each roll is all tangent with straight line; Transmission mechanism is connected with the part roll mandrel, with roll mandrel that transmission mechanism is connected on the linear velocity of roll at the place, point of contact equate.
When using this straightener, the fence upright that needs alignment is put into up and down annular groove on two rolls, provide power to pass through transmission mechanism, roll mandrel drive roll rotation at motor, fence upright promptly is admitted between the two rows roll, finish the purpose of alignment, alignment fast, efficiently, and is simple to operate.
As improvement, in the above-mentioned straightener, roll mandrel becomes flexible connection moving up and down with frame.Can regulate up and down the distance of two rolls like this, to adapt to the fence upright of different tube diameters and differently curved degree in vertical direction.
In the above-mentioned straightener, the roll of left part preferably is oppositely arranged up and down, the setting of staggering up and down of the roll of right side part; And the roll mandrel of the roll that is oppositely arranged up and down all is connected with transmission mechanism; Stagger up and down in the roll that is provided with, the roll mandrel of below all is connected with transmission mechanism.The fence upright that needs alignment enters from the roll shop building of left part, and the roll that is oppositely arranged up and down can be given the bigger active force of fence upright under the drive of transmission mechanism, easier fence upright is sent between the two rows roll.
In the above-mentioned straightener, roll is detachably connected on the roll mandrel.Can change the roll that has the different size annular groove like this, to adapt to the different tube diameters fence upright.
Description of drawings
Fig. 1 is a front view of the present utility model
Fig. 2 is the right view (amplification) of Fig. 1
Fig. 3 is the relative position schematic diagram of each roll among Fig. 1
The specific embodiment
The fence upright straightener comprises buncher 1 among the figure, shaft coupling 2, decelerator 3, gear drive 4, frame, roll mandrel 7, adjusting screw(rod) 10.Frame comprises base 5, side plate 6, and side plate 6 places on the base 5.
Seven roll 8 rows of being arranged in, six rolls 9 are arranged in down row, and each roll is all tangent with straight line.Eight rolls of the row up and down of left part are oppositely arranged, and promptly roll 81,82,83,84 is oppositely arranged with roll 91,92,93,94 respectively; The setting of staggering up and down of the roll of right side part, promptly roll 85,86,87 respectively with roll 95,96 setting of staggering.It is the annular groove 11 of arc that cross section is arranged on the outer circumference surface of each roll.Each roll is detachably connected on the roll mandrel 7, the roll mandrel two ends are connected with side plate 6 by bearing 12, on side plate 6, be provided with roll shop building apart from adjusting screw(rod) 10, adjusting screw(rod) 10 with on the push aside bearing block of roll shaft upper bearing (metal) 12 be connected, bearing block slides up and down with side plate 6 and is connected.Roll adjusting screw(rod) 10 by rotation, can the row's of adjusting roll shaft 8 with the distance of roller 9 vertical direction of pushing aside down, make crooked fence upright pass through roll very easily.
The roll mandrel of arranging eight rolls up and down 7 that connects left part links to each other with decelerator 3 by the gear drive of being made up of gear 41,42,43 etc., and gear 41 is connected on the roll mandrel 7.The roll mandrel 7 that connects two rolls of following row of right side part links to each other with decelerator 3 by the gear drive of being made up of gear 44,45,42,43 etc., and gear 44 is connected on two roll mandrels 7 of following row of right side part.Decelerator 3 links to each other with motor 1 by shaft coupling 2, provides power by motor 1.Gear drive 4 actions, two rolls of the following row who arranges eight rolls, right side part up and down of left part promptly rotate, and they equate in the linear velocity at place, point of contact.Gear drive 4 is a prior art, is not described in detail.
Rectified in the annular groove of the roller of pushing aside up and down that whole fence upright enters left part, rectify by thick, thin rectifying waited roll, rectifys whole good fence upright in the output of the right side port of export at last.
The utlity model has following good effect:
1, guarantee by the machinery location because the utility model is installed the roll mandrel of rectifying whole roll, and adjustable surplus is arranged, so can With the effective linearity that guarantees to be rectified whole fence upright.
2, because the vertical interval of upper bottom roll is adjustable, respectively roll so can regulate according to the degree of crook of being rectified whole fence upright The spacing of roller is rectified the complete machine structure and can be rectified whole purpose again to reach can be entered by strong whole workpiece.
