Description
Technical field
The present invention relates in the metallurgical machinery sector roll-type section straightener multiple roll ring and align locking device simultaneously fast, this device is mainly used in aligning of metallurgy industry steel rolling product roll-type section straightener collars and locking fast.
Background technology
At present, the roll-type section straightener is a section rolling production line Runout area key equipment, can align multiple section bars such as H shaped steel, I-steel, angle steel, channel-section steels.Roll-type section straightener common type is freely supported structure and cantilever design.The freely supported structure straightener is promptly aligned the zone between two frames, forms the simply supported beam stress, and the freely supported structure straightener also claims the dual-support structure straightener.Its advantage is that housing rigidity is higher, and is in light weight, and two fulcrum rollers are stressed evenly, are applicable to aligning heavy section steel and beam-and-rail; Its shortcoming is to change the collars difficulty, and structure is loaded down with trivial details, operation inconvenience.The cantilevered straightener is promptly aligned the side of zone two frames, forms the cantilever beam stress.Its advantage is easy to operate, and roll change is easy, adjusts flexibly; Its shortcoming is when the big specification section bar of aligning, because stressed inhomogeneities can influence final straightening quality.Generally adopting freely supported structure so align big specification section bar at present, is crucial but align the locking problem fast when solve changing collars.Roll-type section straightener collars is changed all to adopt both at home and abroad and directly collars is enclosed within on the roll shaft one by one successively at present, connects with key, holds out against by nut to be fixed on the roll shaft.But there are many problems in this method, mainly is that collars aligns the required precision height with roll shaft in changing collars, the keyway on the collars be difficult for and roll shaft on key align.Use nut to hold out against collars in addition, need artificial execute-in-place, occur error and time-consuming easily.Therefore develop a kind of section straightener multiple roll ring and align the new problem that locking device is the urgent need solution simultaneously fast.
Summary of the invention
The section straightener multiple roll ring that the purpose of this invention is to provide a kind of brand-new design, technology and manufacturing philosophy aligns simultaneously locking device fast, adopts hydraulic principle that combined-type roll collar is pressurizeed, and the axis of cone by both sides aligns and lock fast collars.
The object of the present invention is achieved like this: a kind of section straightener multiple roll ring aligns locking device simultaneously fast, whole device is by the fixation side axis of cone, the fixation side bearing block, the taper hole ring, combined-type roll collar, roll shaft, the mobile side axis of cone, mobile side shaft holder, hydraulic nut is formed, the fixation side axis of cone is installed on the fixation side bearing block, its conical surface end adopts with roll shaft one end and is threaded, the other end of roll shaft passes the combined-type roll collar and the mobile side axis of cone, the taper hole ring has been closed with the bolt handle in the two ends of combined-type roll collar, the mobile side axis of cone is installed on the mobile side shaft holder, mobile side axis of cone conical surface end has taper hole and guider is arranged, roll shaft can pass the mobile side axis of cone along guider and be connected with hydraulic nut, the fixation side axis of cone and the mobile side axis of cone are clipped in the middle combined-type roll collar, finish aligning and locking fast combined-type roll collar by the fixation side axis of cone and the mobile side axis of cone.
Main points of the present invention are its structure and operation principle.Its operation principle is: the fixation side axis of cone is installed on the fixation side bearing block, and roll shaft one end adopts with the fixation side axis of cone and is threaded, and the other end is connected with hydraulic nut, and hydraulic nut piston ring end face combines with the seam end face of the mobile side axis of cone; Can make the fixation side axis of cone and the mobile side axis of cone, taper hole ring, combined-type roll collar form an integral body like this, align with common torque; This device at first aligns, and then finishes quick locking; Its multiple roll ring is achieved in that to orthofunction the mobile side axis of cone has taper hole and guide frame simultaneously, roll shaft is passed easily, make the fixation side axis of cone and the mobile side axis of cone guarantee coaxial running simultaneously, the combined-type roll collar two ends make it close the taper hole ring into as a whole with bolt, the conical surface of the fixation side axis of cone and the mobile side axis of cone contacts with the taper hole of taper hole ring, make combined-type roll collar and the fixation side axis of cone and coaxial the aligning of the mobile side axis of cone, thus when realizing the multiple roll ring to orthofunction.The quick locking effect of this device is achieved in that hydraulic nut relies on to be threaded and forms relative static with roll shaft, hydraulic nut relies on hydraulic power to promote the mobile side axis of cone and moves to fixation side, at this moment the fixation side axis of cone and the mobile side axis of cone form pressure to the taper hole ring at combined-type roll collar two ends, thereby realize the locking effect fast simultaneously of multiple roll ring.
Section straightener multiple roll ring aligns locking device compared with prior art simultaneously fast, have novel science, adjust convenient disassembly, the steady safety of run-in synchronism, long service life, hydraulic control precision advantages of higher, will be widely used in the metallurgical machinery sector.
