Abstract
The invention relates to a finishing mill collar assembly and detection method, aiming to increase the assembly quality of the wire stock finishing mill collar and reduce the fault. The method of the invention comprises the following steps: sleeving a collar on an axle head through a taper sleeve, exerting an axial force to the taper sleeve to ensure that the taper sleeve generates elastic deformation and no relative displacement exists between the collar and the axle head; using a 0.05-0.10mm of filler gauge to detect whether the straight-line segment of the axle head and the taper sleeve has the clearance or not, wherein if part of the filler gauge can not be squeezed in, the grinding deformation point is needed to be removed for installing the filler gauge again; installing the standard taper sleeve without the collar on the axle head to be measured, pressurizing to 20MPa, and using an outside micrometer to separately measure the outside diameter of the deformed taper sleeve at a plurality of positions for comparison, wherein when the average difference reaches 0.04 mm, the axle head of the mill is needed to change.
Description
Technical field
The present invention relates to finishing mill collar assembly and detection method in a kind of wire rod rolling system.
Background technology
In STAINLESS STEEL WIRE was produced, it is more frequent that the mm finishing mill unit collars skids, collars is torn to get off failure ratio open, influences the ordinary production of STAINLESS STEEL WIRE, not only cause steel scrap midway, both wasted energy, increase the spare part cost again, also increase fault time, more seriously production assurance is not.
Summary of the invention
The present invention seeks to overcome the deficiency of above-mentioned prior art, a kind of finishing mill collar assembly and detection method that improves wire finishing mill collars assembly quality, reduces fault is provided.
The inventive method is:
(1) collars is installed; Collars is contained on the spindle nose by tapered sleeve, and tapered sleeve is applied axial force, makes tapered sleeve produce strain, ensures that collars and spindle nose do not have relative displacement in rolling process.That add axial force generally is 38MPa-40MPa;
(2) detect assemblage gap; Whether with the straightway of tapered sleeve gapped, do not enter as if partial plugs if detecting spindle nose with the 0.05-0.10mm clearance gauge, ressemble after need pulling down the reconditioning deformation point.Because tapered sleeve, spindle nose straightway gap 0.18mm-0.28mm, tapered sleeve is easy to dress partially in the practical set process, or spindle nose local deformation, but be difficult for being checked through, cause spindle nose and tapered sleeve straightway part to contact, influence the collars tapered sleeve effect be installed, cause collars to skid or in the authorized pressure scope collars, tapered sleeve do not tear open any more.
(3) detect spindle nose; Be enclosed within the situation of not adorning collars with standard cone, tapered sleeve is installed on the spindle nose to be detected, behind the pressurization 20MPa, measure tapered sleeve distortion back outside dimension respectively in the tapered sleeve many places with outside micrometer, compare, when mean difference reaches 0.04mm, illustrate that the wearing and tearing of the spindle nose conical surface are to scrapping the limit, spindle nose and tapered sleeve two conical surface contacts area reduce, and will cause the collars tapered sleeve to skid, and must change the milling train spindle nose.
Because the spindle nose conical surface is a working face, frequent roll change ring, tapered sleeve and collars skid cause the spindle nose wearing and tearing and wear and tear inhomogeneous, about conical surface wearing and tearing 0.05mm be difficult to detected.
The inventive method can in time detect critical defects such as collars skids, collars is not torn open any more before fault takes place, to these defective advanced processing, can reduce the finishing mill fault rate, improves wire finishing mill collars assembly quality, improves the wire product quality in kind.
The specific embodiment
When checking spindle nose, rusty stain is removed,, checked that the spindle nose window has or not projection, cusped edge, if projection, cusped edge are arranged, uses the file reconditioning the spindle nose scrub with waterproof abrasive paper.
Use the standard tapered sleeve, be enclosed within on the spindle nose, check whether tapered sleeve contacts with the spindle nose straightway, if it is not in place that tapered sleeve is installed, illustrate that then the spindle nose straightway has distortion, contact with tapered sleeve, can not assemble this moment, needs the reconditioning spindle nose. if not reconditioning is difficult to after the assembling pull down, tapered sleeve may be pulled out mashed, even scrap collars. generally measure tapered sleeve distortion back outside dimension respectively at tapered sleeve 5-6 place with outside micrometer, when average-size differed by more than or equal 0.04mm, spindle nose conical surface size has exceeded standard to be needed to change, otherwise cause collars tension force not enough, easily cause the collars sipping fault.
Behind the check spindle nose zero defect, spindle nose is wiped clean with toilet paper.With toilet paper collars, tapered sleeve being wiped clean, collars is contained in the tapered sleeve outer ring, does not align with the collars outer face in the tapered sleeve end, be apart from collars outer face 5mm, prevent that collars, tapered sleeve from installing to spindle nose after, the tapered sleeve displacement is not enough, influences tapered sleeve deformation degree, the tension force deficiency.
The tapered sleeve level that is with collars is contained on the spindle nose, shifts collars onto position, the collars end face is close to labyrinth ring.Check with clearance gauge whether the tapered sleeve straightway contacts with the spindle nose straightway, prevent the tapered sleeve dress partially, local contact, when tapered sleeve being executed external force with hydraulic tool, the tapered sleeve local pressure, inhomogeneous deformation causes the suffered tension force inequality of collars, be easy to cause the relative tapered sleeve generation of collars relative displacement, cause heap steel accident.After clearance gauge is checked tapered sleeve and the spindle nose straightway is contacted, must pull down and ressemble.
Claims (2)
1. finishing mill collar assembly and detection method is characterized in that:
(1) collars is installed; Collars is contained on the spindle nose by tapered sleeve, and tapered sleeve is applied axial force, makes tapered sleeve produce strain, ensures that collars and spindle nose do not have relative displacement in rolling process; That add axial force generally is 38MPa-40MPa;
(2) detect assemblage gap; Whether with the straightway of tapered sleeve gapped, do not enter as if partial plugs if detecting spindle nose with the 0.05-0.10mm clearance gauge, ressemble after need pulling down the reconditioning deformation point;
(3) detect spindle nose; Be enclosed within the situation of not adorning collars with standard cone, tapered sleeve is installed on the spindle nose to be detected, behind the pressurization 20MPa, measure tapered sleeve distortion back outside dimension respectively in the tapered sleeve many places, compare,, must change the milling train spindle nose when mean difference reaches 0.04mm with outside micrometer.
2. finishing mill collar assembly and detection method as claimed in claim 1 is characterized in that measuring tapered sleeve distortion back outside dimension respectively at tapered sleeve 5-6 place with outside micrometer, compares.
