Abstract
A method for efficiently correcting the bend and flexure of a U-shaped steel sheet pile, especially having an arm, is provided. To eliminate the bend of such a steel sheet pile, the outer side of one flange of the steel sheet pile and the inner side of the other are pressed at the same time. To eliminate the flexure of such a steel sheet pile, correction rollers are used for restraining a web, flanges and arms of the steel sheet pile from the upper and lower sides.
Description
The present invention relates to for example be used in the U shaped steel sheet pile of building, building, between flange and joint, have the antidote of U shaped steel sheet pile of wrist and the rectification worker mould of U shaped steel sheet pile.
Usually utilize the steel sheet pile after the hot rolling manufacturing cuts into certain-length, when cooling because of internal stress in shape defect phenomenons such as length direction generation reflex action, bendings.
So-called " reflex action " refer to shown in the C among Fig. 1, becomes the macrobending and the end bending of the direction at right angle with the steel plate pile lining 2 of U shaped steel sheet pile 1.So-called " bending " refer to shown in the B among Fig. 2, becomes the macrobending and the end bending of parallel direction with the steel sheet pile arm 2 of U shaped steel sheet pile 1.According to the specification of JISA 5528, U shaped steel sheet pile be bent into the following steel sheet pile of length 10m in total length * below 0.12%, the steel sheet pile that surpasses 10m is (a total length-10m) * below the 0.10%+12mm.Reflex action is the following steel sheet pile of length 10m in total length * below 0.25%, be (total length-10m) * below the 0.20%+25mm when surpassing 10m.
The rectification of this shape defect is carried out with the roller arbor press usually.But because this roller arbor press jagged configuration below 4 upper rolls with respect to above 3 rollers of roller, so the steel sheet pile rear and front end can not produce sufficient rectification effect.Especially the reflex action of front and back end and crooked bad being not easy are corrected with the roller arbor press, after correcting through roller, only the front and back end are corrected with the punching press arbor press usually.
Fig. 3 is when being corrected the U shaped steel sheet pile 1 generation reflex action of material, the corrective operations figure that utilizes this punching press arbor press to correct.Among the figure, setting applies the crimping bar (not shown) of stamping press in direction shown in the arrow via worker's mould 5, at opposition side then as shown in FIG., be provided with the U shaped steel sheet pile 1 be used for supporting being corrected material a flange outside 42 worker's moulds 6,8 and moving of material corrected in constraint.

The reflex action antidote of traditional U shaped steel sheet pile has many kinds.For example special opening in a pair of correct roller up and down that discloses a kind of rectification portion at the web with clamping U shaped steel sheet pile and flange in the clear 61-63316 communique, the rectification portion both sides that are adjacent to the top correct roller are provided with the direction of the contained portion of joint of the connector portions of constraint U shaped steel sheet pile.The spy opens in the clear 55-70418 communique also same announcement.
As shown in Figure 5, the correct roller 10 of U shaped steel sheet pile utilizes correct roller 10a, the 10b to separate respectively, and roller 18 is restrained web 12, flange 14, the outside of joint 16 and about repeating, the detorsion that bends right and left corrects, and adjusts whole width dimensions of finished products again with the roller 18 in constraint joint 16 outsides.Carry out detorsion because of constraint web, flange, so the finished product section configuration can be out of shape.
Yet, as shown in Figure 6,, to correct if carry out repeated flex if when having the U shaped steel sheet pile of wrist 19 between crimp head 16 and the flange 14, the section of last flange and formed angle of joint and purpose finished product becomes inequality.
Purpose of the present invention is the antidote of left and right directions bending that a kind of U shaped steel sheet pile that solves existing method is provided, and the novel antidote of the shortcoming of house of correction recruitment mould, and employed worker's mould.
Specific purposes of the present invention for provide a kind of can high efficiency rectification U shaped steel sheet pile in, especially between flange and joint (claw), have antidote and employed worker's mould thereof of " bending " of the high steel sheet pile of the flexural property of finishing die directions such as U shaped steel sheet pile of wrist.
The present inventor finds: for the bending of the high steel sheet pile of the flexural rigidity of correcting the finished product transverse direction easily, except the flange outside of crimping one side, it is comparatively effective simultaneously the flange inner face of opposite side to be crimped on same direction again.
During reflex action that the present inventor research is corrected the U shaped steel sheet pile with wrist with roller, find after the flange problem different with angle on target with the formed angle of joint, the profile constraints of just comprehensively carrying out web and flange is obviously abundant inadequately, must comprise that wrist carries out profile constraints, the roller that preferably will retrain web, flange and wrist all forms one up and down, could correct wrist with pinpoint accuracy, thereby invent method of the present invention.
The method of the bending of the left and right directions that the present invention takes place when correcting the course of hot rolling of U shaped steel sheet pile is characterized by the flange outside of a side of this steel sheet pile of crimping, the flange inner face of the opposite side of crimping simultaneously.
In addition, being characterized as of the rectification worker mould of U shaped steel sheet pile of the present invention: combination have crimping U shaped steel sheet pile a side flange outside face the 1st worker's mould and have the 2nd worker's mould of the face of another flange inner face of crimping with being linked to the 1st worker's mould.

According to antidote of the present invention, corrected the outside 22 of a side flange 21 of the U shaped steel sheet pile 20 of material with the stamping press crimping shown in the arrow among Fig. 7, inner face 23 with the flange 21 of opposite side is crimped on same direction simultaneously, so external force can only not concentrate on a side of flange 21,21, the former width that finished product can not take place becomes narrow and small, or local deformations such as local recess take place flange 21,21.
At this moment, the stamping press of the outside 22 of the flange 21 of crimping one side can be identical or slightly different with the stamping press of the inner face 23 of crimping flange 21.But for the width variation that prevents finished product and the local deformation of flange, preferably as far as possible with identical stamping press crimping two sides.
According to existing method, as shown in Figure 3, only apply stamping press, so shown in Fig. 4 (b), local deformations such as locality recess take place on the flange of a side of accepting crimping in the flange outside of U shaped steel sheet pile 1.
Fig. 8 is an embodiment of the employed worker's mould of antidote of the present invention.This worker's mould is by the 1st worker mould 24 of contact as the outside 22 of the flange 21 of the U shaped steel sheet pile 20 of being corrected material, and the 2nd worker's mould 25 that reaches the inner face 23 of crossing over these flange 21 another flanges 21 of contact constitutes.Later on the 1st worker's mould is called worker's mould A, the 2nd worker's mould is called worker's mould B.
Among Fig. 8, worker's mould A and worker's mould B are linked by linking portion 26, also can be for example that worker's mould A and worker's mould B is chimeric and fixing to pass the bolt 28 that is located at the bolt hole 27 on worker's mould B.It links form and can be Construction integration, or only utilize chimeric, pin and combining of pin-and-hole etc.But above-mentioned chimeric bolt mode is the simplest and reliable.
After so forming, be arranged at the stamping press that applies the stamping press of the direction of arrow on the punching press bump linking part 29 of worker's mould A and on worker's mould A, B, apply equidirectional among the figure, respectively 2 flange surfaces of crimping and implement antidote of the present invention.
For easy processing, worker's mould A and worker's mould B can load and unload at linking portion among the figure, but also can form as one.
Other embodiment so that can adjust the relative position of worker mould A and worker's mould B at the width of finished product, utilize linking portion in conjunction with worker mould A and worker mould B with replacement for spacious and comfortable portion is set at the chimeric position of 2 worker's moulds.So, the stamping press in the time of can cooperating the suitable distribution crimping simultaneously flange outside of the dimensional variations (width variation) of being corrected material with another flange inner face is avoided can high efficiencyly being corrected by the generation local deformation of rolling material.
This kenel also can be as shown in Figure 9, and the linking portion 26 of worker's mould A24 and worker's mould B25 is formed a kind of sliding type, makes it can be to direction of arrow inching, and for example bolt type fixed mechanism (not shown) is set in the above.
In any case, when utilizing punching press orthosis of the present invention to correct U shaped steel sheet pile crooked, for example shown in Figure 8, when U shaped steel sheet pile 20 is walked on carrying roller R and is arrived certain position, earlier to fix by worker's mould that combination was constituted of worker's mould A and B, then, direction shown in the arrow applies stamping press in figure.At this moment, by the fixing fixed position of worker's mould as shown in Figure 3,, corrected 2 uses of support side installing of material respectively 1 of punching press side installing.Its concrete corrective operations is identical with existing method, its explanation of Therefore, omited.
Be illustrated in the steel sheet pile that has wrist between joint (claw) and the flange among Fig. 8, but also can be general (not having above-mentioned wrist) U shaped steel sheet pile.As long as worker's mould form fit finished form is changed a little and can implement.The effect that the present invention produced is also identical.Corrected the posture of material among the figure and represented the U type, but opposite, the posture of inverted U also can, as long as cooperate the shape reverse of being corrected material change a job mould up and down.
Below the roller orthosis of the reflex action of U shaped steel sheet pile is corrected in explanation.
Figure 10 is the configuration instruction figure of the correct roller of the U shaped steel sheet pile with wrist of the correct roller of one embodiment of the invention.Among the figure, the U shaped steel sheet pile with web 30, flange 32, wrist 34 and joint 35 is with upside roller 36,36, lower roll 38,38 and outside roller 40 constraint web, flange and wrists.Among the figure, correct roller 36,38 becomes one up and down, so that with same roller constraint web 30 and flange 32.
The angle of the wrist 34 before correcting and flange 32 formed angles and end product not simultaneously, also can rake be set at the position of the wrist 34 that retrains roller 36,38 and repeat carry out detorsion, make it become the angle identical with finished product.
Figure 11 (a) and (b) utilize the figure of the embodiment that roller of the present invention corrects when being illustrated in this situation.With Figure 10 difference for the rake of angle [alpha] is set respectively at roller 36,38.
In any case above, all use web, flange, reach the correct roller of wrist from the above-below direction constraint.Especially in Figure 11 (a) and (b), during wrist between containment flange and joint, use the angle different with the finished product section to be set and from the contained correct roller of above-below direction.
As if among the above embodiment, the roll shaft of up- down rollers 36,38 becomes consistent configuration in vertical direction, but in fact, up-down rollers is for being configured to zigzag.
Below explanation utilizes the high efficiency principle of carrying out the roller rectification of above-mentioned constraint.
That is repeated flex is corrected and is carried out 3 supports for utilization is configured to jagged up-down rollers.But suppose fulcrum at the downside roller, the force is when the upside roller, and then as shown in figure 12, if wrist 34 is a unconfinement, then wrist 34 diminishes with flange 32 formed angles.That is the direction of the angle of elevation θ of wrist 34 distortion becoming increase.That is among the figure, wrist 34 deforms towards the direction of arrow.If when retraining top 34 up and down, the section configuration of U shaped steel sheet pile is by the shape that remains unchanged according to the present invention.
If fulcrum is at the upside roller, the force is when the downside roller, and as shown in figure 13, if wrist 34 is a unconfinement, then wrist 34 increases with flange 32 formed angles, that is wrist 34 becomes big direction distortion downwards towards angle θ.That is among the figure, wrist 34 is out of shape towards the direction of arrow.Section configuration when retraining wrist 34 according to the present invention does not deform and is kept.
Therefore, in the present invention, with same roller constraint wrist, web and flange, preferably from up and down with same roller constraint web and flange, can be with 12, shown in Figure 13 identical, do not damage the finished product section configuration and correct.Especially with the roller pass constraint whole sections except joint, not only can high efficiency reflex action up and down of correcting U shaped steel sheet pile, and the bending of can high efficiency rectification slight left and right directions.
As mentioned above, according to the present invention, compare with U shaped steel sheet pile with wrist, even have U shaped steel sheet pile to the high wrist of the rigidity of reflex action, still can utilize punching press rectification or roller to correct and remove the hettocyrtosis of left and right directions and the reflex action of above-below direction easily, can keep certain wrist angle this moment again.
