Abstract
The flat-rolled roller of one kind production " Z " steel band of model, is made up of the up-down rollers of a pair of mutual cooperations, it is characterised in that the up-down rollers are constituted by the multilayer flaggy of coaxial aperture.The flat-rolled roller that the present invention the is provided beneficial effect maximum compared to the roll of existing " Z " steel band of model is that the utilization rate of its roll is greatly improved, while also having the convenient advantage of pass adjustment.
Description
Technical field
The invention belongs to steel processing and forming field, a kind of flat-rolled roller is specifically related to.
Background technology
At present, the production of Z-shape steel band is roughly divided into special-shaped wire rod die drawing method and roller die drawing or roller die cold-rolling practice.Wherein special-shaped wire rod die drawing method is using the special-shaped wire rod after hot rolling as raw material, net shape is pulled into overall die drawing, the shortcoming of this method is, Mold Making is difficult, service life is short, low production efficiency and high cost, gained steel band is of poor quality, performance is low, defect is more, size is unstable etc., such as patent 1CN86210451 is that the side for carrying out light reduction to Z-shape steel band by adding edging roll after flat-rolled roller is rolled, the reduction of the residual stress of gained Z-shape steel band is realized, but this improvement is very limited.
And roller die drawing or roller die cold-rolling practice have the advantages that small, handling ease is lost in mould, and gained steel band lumber recovery is high, and performance is good, and obtains first time national science conference award, thus is used widely.
With the application of roller die drawing and roller die cold-rolling practice, the requirement more and more higher to rolling device improves also more and more, for example, (improvement [J] the metallic articles that roll is assembled in the production of Yu Xingang, Guo Zhanlin, Lu Wenhe .Z shaped steel wires of document 1：2001,27-6) the roll assembling to Z-shape steel silk is improved twice, is improved the life-span of bearing and roll, has significantly been saved production cost.
But above-mentioned improving all simply is improved Z-shape steel with the auxiliary process and equipment in production process, and actually key of the Z-shape steel with precise forming is the pass of the flat-rolled roller used, for applied to the armor Z-shape steel band in the oil producing operation of deep-sea, it is high to its pressure-resistant performance requirement, steel band is coordinated and requires fine, simple Z-shaped structure can not meet application.
The content of the invention
The present invention is for a kind of the not enough there is provided flat-rolled roller for producing Z-shape steel band of existing Z-shape steel band, and the Z-type ultimate tensile strength that the flat-rolled roller provided using the present invention is produced can reach 350-384MPa.
The flat-rolled roller that the present invention is provided is made up of the up-down rollers of a pair of mutual cooperations, two rollers are made up of the multilayer flaggy of coaxial aperture, and roll surface rolling section is divided into 5 regions vertically, respectively positioned at two end sheaths at two ends and three casement areas, the casement area of lower roll is made up of tail end profiled sheeting, wing plate profiled sheeting and flat board, wherein wing plate profiled sheeting edge is fillet, is not more than 1 with the thickness ratio of tail end profiled sheeting：4；The casement area of upper roller is except including and lower roll function identical tail end profiled sheeting, outside wing plate profiled sheeting and flat board, holding force plate is additionally provided between flat board and wing plate profiled sheeting, after assembling, the tail end shaping plate thickness of the flat board of upper roller and lower roll is equal and position is relative, the end of lower roll-out sheet and the tail end profiled sheeting end part aligning of upper roller, described holding force plate is the steel plate after both side surface roughening is handled, deformed with the relative displacement for reducing both sides flat board and wing plate profiled sheeting, in assembling, according to required " Z " shape steel web thickness requirement, to select the upper roller holding force plate of different-thickness, the requirement that the thickness of lower roll-out sheet then aligns according to the casement area of lower roll and upper roller is selected, i.e. its thickness is determined by the thickness of holding force plate.
The flat-rolled roller that the present invention the is provided beneficial effect maximum compared to the roll of existing " Z " steel band of model is that the utilization rate of its roll is greatly improved, its reason is, roll is in use, the loss rate of different zones is inconsistent, the loss of pass area is most fast, existing roll is after pass area loss to " Z " steel band of model deformation, just can only whole roller change, and the flat-rolled roller that the present invention is provided can be according to active loss speed, timely change the flaggy specified, changed without whole roller, such as, in practical application, the loss of wing plate profiled sheeting is most fast, therefore, in assembling, the identical replacement plate of wing plate profiled sheeting typically all has more 5-8 blocks or so than other flaggies, it can be seen that, the roll utilization rate of the present invention is greatly enhanced.
In addition, the flat-rolled roller that the present invention is provided also has the convenient advantage of pass adjustment, in existing " Z " steel band of model processing, various sizes of " Z " shaped steel is processed if desired, different shaped jet holes can only be obtained by changing the realization of whole group roll (only the obtainable pass of roll gap is very limited amount of above and below adjustment), and the flat-rolled roller that the present invention is provided, the pass of sizes can be obtained by changing the wing plate profiled sheeting of different-diameter and each flaggy of different-thickness, this is provided a great convenience to reality processing.
