Abstract
A kind of stretcher leveling method and device thereof of metal material, rectified material with two pair of rollers clampings to roll propelling to a direction simultaneously, the linear velocity that two pair of rollers are rotated is inequality, and applies to being rectified material that a tensile stress realizes the aligning of being rectified material.This device can continuous straightening.The efficient height, and simple in structure, it is all convenient to make, adjust, operate.
Description
The invention belongs to the stretcher leveling method and the device thereof of metal material aligning usefulness.
At present, mainly be to have taked following several method to the aligning of metal material: (1) multiple roll method for aligning, promptly use " Bauschinger effect " that metal material is carried out repeatedly positive contraflexure, make multiple original curvature progressively become single curvature, and its aligning the most at last; (2) method for gag press straightening of detorsion; (3) drawing process that carries out stretch-draw with stretched mechanical clamping metal material two ends.Though more than first kind of multiple roll method for aligning material is carried out continuous straightening, because of its roller quantity is many, so its complex structure is made, adjusted, the equal difficulty of operation; Second kind, the third method for aligning all can not continuous straightenings, and efficient is low, and second kind of method for gag press straightening also exist can only be to the defective of part aligning.
Purpose of the present invention just is to provide a kind of can carry out continuous straightening, and simple in structure, makes, adjusts, operates all stretcher leveling method easily and device thereof.
Below in conjunction with accompanying drawing principle of the present invention and two specific embodiment are described in detail.
Accompanying drawing one: the principle schematic of stretcher leveling method
Wherein: D

2Top discharge roller D
2' bottom discharge roller
9 are rectified material
Main points of the present invention are to use two pair of rollers, i.e. enterprising material roller, lower feed roller and top discharge roller, the clamping of bottom discharge roller rectified metal material and rotated, and makes by strong material traveling priority. Work as V1＝V
1′，V
2＝V
2' and V1＝V
1′＜V
2＝V
2′（V
1Be the linear velocity of enterprising material roller, V1' be the linear velocity of lower feed roller, V2Be the linear velocity of top discharge roller, V2' for the linear velocity of bottom discharge roller) time, because the differential of two pair of rollers rotates, just the quilt between two pair of rollers is rectified material and is produced tension force, produce on the material section tensile stress sigma draw and make its tensile stress sigma widen in the yield strength σ that equals to be rectified materials, less than the tensile strength sigma of being rectified materialb, i.e. σs≤σ
Draw≤σ
b, just can make by strong material and be aligned and can not be broken.
The structural representation of accompanying drawing two: embodiment one
Wherein: 1 driving shaft, 2 Hooks coupling universal couplings

2' just to set up, the two ends of the roll shaft of two lower rolls are installed in respectively on the fixing nonadjustable bearing, and the two ends of the roll shaft of two top rolls are compressed spring compression respectively, and by screw rod the compression spring is adjusted.So running is rectified material and can be obtained tension force between two pair of rollers and aligned.
The structural representation of accompanying drawing three: embodiment two
When power (moment of torsion) is imported by driving shaft, through driving gear Z1Drive four driven gear Z2、Z

5The time, because the number of teeth of four driven gears is in twos identical, i.e. Z2The number of teeth=Z4The number of teeth, Z3The number of teeth=Z5The number of teeth, and Z2、Z
4The number of teeth less than Z3、Z
5The number of teeth, thereby their rotating speed is just not identical. These four driven gears are connected with four roll shafts by Hooks coupling universal coupling respectively again, drive four smoothing rolls, when the roller of four smoothing rolls footpath is identical, i.e. and R1＝R
1′＝R
2＝R
2' time, V1＝V
1′＜V
2＝V
2' just set up. The two ends of the roll shaft of two lower rolls are installed in respectively on the fixing nonadjustable bearing, and compressed spring compression is distinguished at the two ends of the roll shaft of two top rolls, and by screw rod Compress Spring are adjusted. So running is rectified material and can be obtained tension force between two pair of rollers and aligned.
If by rectifying material is plate, band, then roller is plain-barreled roll (promptly not having roller slotted eye type); If by rectifying material is type, bar, then roller can be made grooved roller (roller slotted eye type is promptly arranged) by the geometry of material section.
