Description

Straightener

The utility model relates to a kind of straightener that is used for alignments such as PAP, steel pipes.

At present, the tubing of bending being carried out alignment, generally is the method that adopts artificial hammering alignment.This method labour intensity is big, and the alignment weak effect damages tubing easily.Particularly for the PAP that is curled into dish, when construction and installation, it is carried out alignment is a problem demanding prompt solution.

The purpose of this utility model is, provides that a kind of labour intensity is little, alignment is effective, do not damage the tubing straightener of tubing.

The purpose of this utility model is achieved in that straightener, comprises frame.Its special character is, roller 1, roller 2 and roller 3 are installed on the frame, and the axis of this three roller is parallel to each other, and roller 3 is above between roller 1 and the roller 2, and the outer rim of this three roller is V-shaped.

Frame is used for installing and supporting other parts.Tubing can pass through in the gap between roller 3 and roller 1 and the roller 2, and when tubing passed through this gap, the part of its bending was by the roller straightening.The outer rim of roller 1, roller 2 and roller 3 is V-shaped, and " V " shape groove can be limited in tubing wherein, makes tubing can both obtain alignment at the sweep of different directions.For softer tubing (for example PAP) when the alignment, can be with the mode of artificial push-and-pull, make tubing pass through gap between roller 3 and roller 1 and the roller 2, thereby with the tubing alignment.For harder tubing (for example steel pipe), can use these three rollers of other drive power source or one to two rotations wherein such as motor, internal combustion engine, make tubing be driven the gap of passing through automatically between roller 3 and roller 1 and the roller 2 by roller, thereby by alignment.For the tubing to different tube diameters and differently curved degree carries out alignment, the gap between roller 3 and roller 1 and the roller 2 can be regulated.

A kind of improvement project of the present utility model is, roller 4 and roller 5 also are installed on the support, the axis of roller 1, roller 2, roller 3, roller 4 and roller 5 is parallel to each other, the axis of roller 1, roller 2 and roller 4 is in a plane, the axis of roller 3 and roller 5 is in another plane, roller 5 is above between roller 2 and the roller 4, and the outer rim of roller 4 and roller 5 is V-shaped.

Tubing is successively by gap, roller 2 and roller 3 and gap, roller 5 and roller 2 between the roller 5 and the gap between the roller 4 between roller 3 and roller 1 and the roller 2, these three gaps can be designed to successively gradually form from large to small, gradually by alignment, the tubing alignment of coming out at last was effective when tubing passed through these three gaps.For the tubing that adapts to different tube diameters and differently curved degree carries out alignment, the size in above-mentioned three gaps can be regulated.

Frame of the present utility model comprises base 6 and swing arm, and swing arm is installed on the base 6 by rotating shaft 8, and roller 1, roller 2 and roller 4 are installed in respectively on the base 6, and roller 3 and roller 5 are installed in respectively in the swing arm, has oscillation adjuster between swing arm and the base 6.

Oscillation adjuster is used to regulate the pendulum angle of swing arm, thereby regulates gap, roller 2 and roller 3 and gap, roller 5 and roller 2 between the roller 5 and the gap between the roller 4 between roller 3 and roller 1 and the roller 2.

Oscillation adjuster of the present utility model comprises bracing frame 9, leading screw 10, nut 11 and handwheel 12; The lower end of bracing frame 9 is installed on the base 6 by rotating shaft 13, and its upper end is equipped with nut 11; Leading screw 10 spiral shells are on nut 11, and its upper end is equipped with handwheel 12, and its lower end is installed in the swing arm.

The utility model is owing to adopt roller to carry out alignment, during the gap of tubing between " V " shape groove of the outer rim by roller, by " V " shape groove straightening.Adopt the utility model that tubing is carried out alignment, alignment process is steady, has avoided tubing is knocked, and has not only reduced labour intensity, and alignment is effective, do not damage tubing.The utility model can be used for the tubing of different tube diameters and differently curved degree is carried out alignment owing to have oscillation adjuster, and is applied widely.When the utility model is used for that the PAP that is curled into dish carried out alignment, can realize the automation alignment, increase work efficiency.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a left view of the present utility model.

As depicted in figs. 1 and 2, present embodiment is a kind of PAP straightener, and it comprises base 6, swing arm, roller 1, roller 2, roller 3, roller 4, roller 5 and oscillation adjuster.Frame is formed in the swing arm of base 6.Swing arm is made up of cursor 7 and crossbeam 14, and the lower end of cursor 7 is installed in the right-hand member of base 6 by rotating shaft 8, and the right-hand member of crossbeam 14 is fixed on the upper end of cursor 7.The equal and opposite in direction of above-mentioned 5 rollers, shape is identical, and their outer rim is V-shaped, and their axis is parallel to each other.Roller 1, roller 2, roller 4 all are installed on the base 6, and their axis is in same plane, and the distance between roller 1 and the roller 2 equates with distance between roller 2 and the roller 4.Roller 3 is above between roller 1 and the roller 2, and roller 5 is above between roller 2 and the roller 4.Roller 3 and roller 5 are installed on the crossbeam 14.Oscillation adjuster comprises bracing frame 9, leading screw 10, nut 11 and handwheel 12.The lower end of bracing frame 9 is installed in the left end of base 6 by rotating shaft 13, and nut 11 is fixed on the upper end of bracing frame 9, and leading screw 10 spiral shells are on nut 11.Handwheel 12 is fixed on the upper end of leading screw 10, and the lower end of leading screw 10 has rotating disk 15, and rotating disk 15 is installed in the hole on the crossbeam 14, and pressing plate 16 is pushed down rotating disk 15, and pressing plate 16 is fixed on the crossbeam 14 by bolt 17.Leading screw 10 can only rotate on crossbeam 14 like this, can not moving axially at crossbeam 14 upper edge leading screws 10.

During use, at first according to the diameter of PAP for the treatment of alignment and the size of degree of crook, gap, roller 2 and roller 3 between roller 3 and roller 1 and the roller 2 and gap, roller 5 and roller 2 between the roller 5 and the gap between the roller 4 are transferred to suitable size.Concrete adjustment process is, rotates handwheel 12, and handwheel 12 drives leading screws 10 and rotates in nut 11.Leading screw 10 rotates and will axially move in nut 11, and the rotating disk 15 of leading screw 10 lower ends drives crossbeam 14 and cursor 78 swing around the shaft by pressing plate 16.Crossbeam 14 drives roller 3 and roller 5 swings, thereby reaches the purpose of regulating gap between the roller with cursor 7 swings.In adjustment process, bracing frame 9 is 13 swings by a small margin around the shaft also.After gap adjustment between the roller is good, PAP 18 in the gap between left side insertion roller 3 and the roller 1, is pulled out from the roller 5 on right side and the gap location between the roller 4 at last, the PAP of pulling out is by the roller alignment.
