Steel pipe straightening device
The utility model is related to a kind of processing unit of phase chromatography-use steel pipe, particularly a kind of steel pipe straightening device.
When carrying out liquid chromatogram operation, it is necessary to use thinner stainless steel tube（Its external diameter is only 1/16 inch）, so
Thin steel pipe is easily bent during using and depositing, and is once bent, then is difficult to recover straight.This is for stainless
The use of steel pipe causes great inconvenience, is formed and wasted.If the steel pipe of bending can be stretched and come into operation again,
Substantial amounts of resource can be saved down, but pipe straightening machine on the market is directed to the relatively large thick steel pipe of external diameter mostly at present（3mm with
On）, and these traditional pipe straightening machines also there are problems that it is complicated, therefore need a kind of to be directed to liquid now

Spectrum, the steel pipe easily bending that diameter is relatively thin actual conditions, design a kind of special structure, it can pass through letter
Single operation, steel pipe is stretched, and goes for the flattening operations of the steel pipe of a variety of different lengths, applied widely；Meanwhile,
It also has simple to operate, quick, the advantages of straightening effect is good, and its manufacture craft is simple, and manufacturing cost is cheap, therefore
It may be said that it possesses a variety of advantages, it is particularly suitable for popularization and application in the art, its market prospects is very wide.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the sectional view of the utility model embodiment.
Fig. 3 is the parts explosion of the utility model embodiment.
Below in conjunction with brief description of the drawings embodiment of the present utility model.As shown in Figure 1, Figure 2, Figure 3 shows：A kind of steel pipe
Support 1 based on straightening device, including one, fixed plate 2 is fixedly connected with one end of support 1, is set in fixed plate 2
Thrust bearing 4 is equipped with, this outside of thrust bearing 4 is pressed in fixed plate 2 by briquetting 3, and bearing plate is socketed with outside briquetting 3
15, and bearing plate 15 can relatively rotate with briquetting 3, while the one side of bearing plate 15 is in contact with thrust bearing 4, in fixation
Movable sleeve in guide pipe 6, the guide pipe 6 is further fixedly arranged on plate 2 and is connected to leading screw 5, one end of this leading screw 5 is through above-mentioned
Thrust bearing 4, briquetting 3 and bearing plate 15, and protrude from the outside of fixed plate 2, hand be threaded with the leading screw 5 of this one end
Wheel 7, and the other end of leading screw 5 is then provided with dynamic chuck 8
Two locking sliding blocks 9 are also slidably connected on support 1, and locking screw thread is further opened with locking sliding block 9
Hole 10, two described locking sliding blocks 9 support a slide plate 11 jointly, and slide plate is provided with the top of slide plate 11 and founds block 12, and
And hollow pipe 13 is additionally provided with the vertical block 12 of slide plate, and hollow pipe 13 is overlapped with the axis of above-mentioned leading screw 5, and in hollow pipe
Clamp first 14 is also associated with 13, and clamp first 14 is located at hollow pipe 13 towards one end of dynamic chuck 8.
The course of work of the steel pipe straightening device of the utility model embodiment is as follows：Locking sliding block 9 and slide plate are driven first
11 slide on support 1, allow the two to drive clamp first 14 to move to the end of support 1, are then adjusted by way of rotation hand wheel 7
The position of the dynamic chuck 8 of section, allows chuck 8 to be more than the length for needing stretch the steel pipe of processing with clamp first the distance between 14
The two ends of steel pipe are utilized respectively dynamic chuck 8 and clamp first 14 are clamped, and screw the locking spiral shell in locking screw thread hole 10 by degree
Nail, allows locking sliding block 9（With clamp first 14）It is fixed on support 1, rotates handwheel 7, allow chuck 8 away from clamp first 14
Direction is moved, and with the progress of above-mentioned motion, the steel pipe of bending can be straightened, and after steel pipe is straightened completely, be rotated further hand
Wheel 7, allows chuck 8 to continue to move to 1% or so of steel pipe total length, carries out the tensioning of steel pipe, after tensioning half a minute, rotates backward
Handwheel, and will be pulled down in the driven chuck 8 of steel pipe and clamp first 14, complete stretching and crystallization operation for steel pipe；
If the length of steel pipe is more than dynamic ultimate range between chuck 8 and clamp first 14, steel pipe can be worn and be connected on
In hollow pipe 13, the passive chuck 8 in one end of steel pipe is clamped, the other end of steel pipe pass through it is hanging after hollow pipe 13, depending on chuck 14
Then it is clamped on the tube wall of steel pipe, that is to say, that the present apparatus can carry out flattening operations to the steel pipe of random length.
The process being adjusted using the position of 7 pairs of dynamic chucks 8 of handwheel is as follows：When handwheel 7 is rotated forward, due to bearing plate
15 and the stop of the grade of fixed plate 2, handwheel 7 can not advance, therefore the leading screw 5 being threadedly coupled with handwheel 7 is retreated relative to handwheel 7
（Moved away from the direction of clamp first 14）, drive dynamic chuck 8 to be moved to the direction of fixed plate 2；Handwheel 7 is rotated backward
When, because the rear of handwheel 7 does not stop, therefore leading screw 5 is motionless, direction of the handwheel 7 on leading screw 5 away from clamp first 14
Motion, when handwheel 7 moves to the end of leading screw 5, operating personnel promote forward handwheel, driving leading screw 5 axial direction in guide pipe 6
Motion, until dynamic chuck 8 moves to desired position.
