Abstract
The invention discloses a composite hard alloy roller which comprises a roller shaft, wherein at least two sections of alloy roller rings are arranged on the roller shaft, a spacing ring is arranged between the adjacent alloy roller rings, one end of the roller shaft is provided with a step used for blocking the alloy roller rings, the other end of the roller shaft is provided with a hydraulic nut, the end surface of a clamping ring of the hydraulic nut is pressed against the end surface of the nearest alloy roller ring, and the clamping ring is sheathed with a locking device which is continuously pressed against the alloy roller ring after the pressure of the hydraulic nut is removed. The composite hard alloy roller has the advantages that the alloy roller rings are clamped by using air pressure to act on the hydraulic nut when the composite hard alloy roller is fixed, and then the relative position is fixed by using a lock washer. The composite hard alloy roller has the advantages of simple structure, time saving and labor saving in operation and good fixing effect, and the service life of the alloy roller rings is prolonged.
Description
Technical field
The present invention relates to a kind of composite hard alloy roll.
Background technology
Roll is wanted the consumption in operation part as rolling mill main, and product quality, production efficiency etc. is all had direct impact.Hard alloy roll is because having the advantages such as single groove steel transportation amount height, negative common difference precise control, product surface quality are good, and having become wire rod rolls face, especially high-speed rod-rolling mill finish rolling, pre-finish rolling, in the main roll material that rolls.
The every reconditioning of hard alloy combined type mill roll once, single groove steel transportation amount reaches more than 800 ~ 1200 tons, is 10 times of nodular cast iron roller.And hard alloy composite roll can increase the reconditioning number of times, and collars axle etc. can be repeatedly used.The benefit advantage is very outstanding, and the steel surface smoothness that shuts out is good.
Present composite ring all adopts the alloy collars is bonded on the roll shaft, but in the Practical manufacturing process, bonding unstable problem appears easily, thereby affect the quality of product, and this mode is also inapplicable to the composite roll that adopts two joints and above alloy collars, adopts simultaneously the mode of welding also can't operate between two joint collars.
How fixing the alloy collars is present subject matter, and we designed the mode of utilizing alloy collars and roll shaft interference fit, but the alloy collars ftractures easily; Also designed and utilized the big nut location, withstood again the mode alloy collars location of alloy collars with a plurality of primary nuts, relatively wasted time and energy but will tighten one by one these primary nuts in the practical operation.
Summary of the invention
The object of the present invention is to provide a kind of composite hard alloy roll, it is fixing difficult effectively to solve existing alloy collars, the problem of complex steps.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of composite hard alloy roll, comprise roll shaft, described roll shaft is provided with at least two joint alloy collars, be provided with spacer ring between the described adjacent alloy collars, one end of described roll shaft is provided with the step that blocks the alloy collars, the other end of described roll shaft is provided with hydraulic nut, the hold-down ring end face of described hydraulic nut withstands on the nearest alloy collars end face, is arranged with the locking device that continues to hold out against the alloy collars after hydraulic nut pressure removes on the described hold-down ring.
Preferably, described locking device is the lock washer of two opposite face band sawtooth, and described lock washer has at least three screwed holes radially, is provided with bolt in the described screwed hole; With two toothed lock washers, can ensure suitable contact-making surface fixedly the time again, can not be out of shape because pressure is excessive.
Preferably, the external diameter of described hydraulic nut is less than the external diameter of alloy collars; Roll in the course of the work locking nut can not get loose.
Preferably, the external diameter of described locking device is less than the external diameter of alloy collars; Do not affect the work of alloy collars, improve spacer ring service life.
Compared with prior art, advantage of the present invention is: this device utilizes fixedly the time air pressure that the hydraulic nut effect is compressed the alloy collars, again with the fixing relative position of lock washer, simple in structure, it is time saving and energy saving to operate, and good fixing effect prolongs alloy collars service life.
Description of drawings
Fig. 1 is the structural representation of a kind of composite hard alloy roll of the present invention.
The specific embodiment
Consult the embodiment that Fig. 1 is a kind of composite hard alloy roll of the present invention, a kind of composite hard alloy roll, comprise roll shaft 1, described roll shaft 1 is provided with at least two joint alloy collars 2, be provided with spacer ring 3 between the described adjacent alloy collars 2, one end of described roll shaft 1 is provided with the step 5 that blocks alloy collars 2, the other end of described roll shaft 1 is provided with hydraulic nut 4, hold-down ring 9 end faces of described hydraulic nut 4 withstand on nearest alloy collars 2 end faces, be arranged with the locking device 6 that after hydraulic nut 4 pressure remove, continues to hold out against alloy collars 2 on the described hold-down ring 9, described locking device 6 is the lock washer of two opposite face band sawtooth, described lock washer has at least three screwed holes 7 radially, be provided with bolt 8 in the described screwed hole 7, the external diameter of described hydraulic nut 4 is less than the external diameter of alloy collars 2, and the external diameter of described locking device 6 is less than the external diameter of alloy collars 2.
With being enclosed within on the roll shaft 1 of alloy collars 2 and spacer ring 3 intervals, then the hydraulic nut 4 of screwing on inflating in the oilhole of air pump to hydraulic pressure nut 4, ejects hold-down ring 9, alloy collars 2 is compressed, regulate two lock washers and move in the other direction, utilize the tooth of two lock washers to eliminate the gap, make a lock washer withstand alloy collars 2, another lock washer withstands hydraulic nut 4, adjusting bolt is fixed the position of two lock washers again, then removes air pump, finishes the fixing of alloy collars 2.This device utilizes air pressure fixedly the time, and 4 effects compress alloy collars 2 to hydraulic nut, and with the fixing relative position of lock washer, simple in structure, it is time saving and energy saving to operate again, good fixing effect, 2 service lifes of prolongation alloy collars.
The above only is specific embodiments of the invention, but technical characterictic of the present invention is not limited to this, and any those skilled in the art is in the field of the invention, and the variation of doing or modification all are encompassed among the claim of the present invention.
