Abstract
The utility model relates to a flat roll that production Z shaped steel area was used is become by a pair of upper and lower roller set of mutually supporting, go up the lower roll and form by the multiply wood layer with the shaft hole, and the rolling cross -section of roll surface is divided into 5 regions along the axial, is lieing in two the end sheaths and the three casement district at both ends respectively, and the casement district of lower roll is by tail end profiled sheeting, pterygoid lamina profiled sheeting and dull and stereotyped the component, and the marginal fillet that is of pterygoid lamina profiled sheeting wherein compares being not more than 1 with the thickness of tail end profiled sheeting: 4, the casement district of going up the roller still is equipped with the power of holding board between dull and stereotyped and pterygoid lamina profiled sheeting except including tail end profiled sheeting, pterygoid lamina profiled sheeting and the flat board with lower roll the same functionality, the assembly back, and the tail end profiled sheeting thickness of going up the dull and stereotyped of roller and lower roll equals that just the position is relative, the tip of lower roll flat board aligns with the tail end profiled sheeting tip of last roller. This tie roll is compared in the utilization ratio of roll in current " Z " shaped steel area and is obtained very big improvement, still has the convenient advantage of pass set -up simultaneously.
Description
Technical field
This utility model belongs to steel processing and forming field, is specifically related to a kind of flat-rolled roller.
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 with the special-shaped wire rod after hot rolling for raw material, it is drawn into net shape with non-detachable mold, the shortcoming of this method is in that, Mold Making difficulty, service life is short, production efficiency is low and cost is high, gained steel band is of poor quality, performance is low, defect is many, size is unstable, such as namely Z-shape steel band is carried out the side rolling of light reduction by patent 1CN86210451 by adding edging roll after flat-rolled roller, achieve the reduction of the residual stress of gained Z-shape steel band, but this to improve effect very limited.
And roller die drawing or roller die cold-rolling practice have the advantages such as little, the handling ease of mould loss, and gained steel band lumber recovery is high, and performance is good, and obtains first time national science conference award, thus is used widely.
Application along with roller die drawing and roller die cold-rolling practice, the requirement of rolling device is more and more higher, improve and also get more and more, such as, document 1 (Yu Xingang, Guo Zhanlin, the improvement [J] of roll assembling in the production of Lu Wenhe .Z shaped steel wire. metallic article: 2001,27-6) the roll assembling of Z-shape steel silk is carried out twice improvement, improve the life-span of bearing and roll, provide significant conservation production cost.
But above-mentioned improvement is all that Z-shape steel has been improved with the auxiliary process in production process and equipment, and the pass of the actually Z-shape steel flat-rolled roller that it is critical only that employing with precise forming, bring particularly with the armor Z-shape steel being applied in the oil producing operation of deep-sea and say, its pressure performance requirement is high, steel band is coordinated and requires that finely simple Z-shaped structure can not meet application.
Summary of the invention
This utility model is for the deficiency of existing Z-shape steel band, it is provided that a kind of flat-rolled roller producing Z-shape steel band, uses the Z-type ultimate tensile strength that the flat-rolled roller that this utility model provides is produced can reach 350-384MPa.
The flat-rolled roller that this utility model provides is made up of the up-down rollers that a pair cooperates, two rollers are made up of the multilamellar flaggy of coaxial aperture, and roll surface rolling cross section is divided into 5 regions vertically, hold sheaths and three casement districts for two that are respectively positioned at two ends, the casement district of lower roll is made up of tail end dieplate, wing plate dieplate and flat board, wherein wing plate dieplate edge is fillet, is not more than 1:4 with the thickness of tail end dieplate ratio；The casement district of top roll is except including the tail end dieplate identical with lower roll function, outside wing plate dieplate and flat board, holding force plate it is additionally provided with between flat board and wing plate dieplate, after assembling, the flat board of top roll is equal with the tail end dieplate thickness of lower roll and position is relative, the tail end dieplate end part aligning of the end of lower roll flat board and top roll, described holding force plate is the steel plate after both side surface roughening processes, relative displacement to reduce both sides flat board and wing plate dieplate deforms, when assembling, according to required " Z " shape steel web thickness requirement, select the top roll holding force plate of different-thickness, the requirement that the thickness of lower roll flat board then aligns according to the casement district of lower roll and top roll selects, namely its thickness is determined by the thickness of holding force plate.
The utilization rate having the beneficial effects that its roll that the flat-rolled roller of this utility model offer is maximum compared to the roll of existing " Z " steel band of model is greatly improved, its reason is, roll is in use, the loss rate of zones of different is inconsistent, the loss of pass district is the fastest, existing roll is after pass district loss to " Z " steel band of model deforms, just can only change by whole roller, and the flat-rolled roller that this utility model provides can according to active loss speed, change the flaggy specified timely, change without whole roller, such as, in practical application, the loss of wing plate dieplate is the fastest, therefore, when assembling, the identical replacement plate of wing plate dieplate generally all has more about 5-8 block than other flaggies, visible, roll utilization rate of the present utility model is greatly enhanced.
In addition, the flat-rolled roller that this utility model provides also has the convenient advantage of pass adjustment, in the processing of existing " Z " steel band of model, if needing processing various sizes of " Z " shaped steel, realize obtaining different shaped jet holes (it is very limited amount of for only adjusting the obtainable pass of up-down rollers spacing) only by changing whole group of roll, and the flat-rolled roller that this utility model provides, can be obtained the pass of sizes by each flaggy of the wing plate dieplate of replacing different-diameter and different-thickness, this provides a great convenience to reality processing.
