Description
Technical field
This utility model relates to cold roll forming milling train product size and quickly remodels technical field, particularly eave tile keyed roll lining fast replacing device.
Background technology
During with cold roll forming mill milling section bar, difference according to requirements, the material (such as: C, U-shaped material etc.) that shape of cross section is identical and size is different can be produced.If each size all produces a milling train, not only cost is the highest, and production site is also impossible to meet requirement.Owing to the cross sectional shape of section bar is the same, requirement can be met by the lateral separation changed between roll, substitute multiple stage milling train.
In order to achieve the above object, the common way of tradition has 2: the first increases bearing bore diameter and the thickness of bearing of back up roll axle, fills an axle sleeve, this axle sleeve be axially positioned by roll between roll mandrel and bearing.When needing the lining changing roll, unclamp nut, move or take off memorial archway, extracting lining and roll.The shortcoming of the method is to cause whole equipment to strengthen owing to bearing strengthens, and cost just increases.And because bearing thickness increases, it is desirable to the memorial archway frame of dress bearing thickeies, and cannot be used for wall board type milling train in this way；It two is the width increasing wall board type milling train, thus sets up two groups of locking nuts at roll two ends, when needing resleeve, unclamps two groups of nuts, lock after finishing changing again.Its shortcoming is that milling train width strengthens, and weight and cost increase, and locking nut is inside wallboard, are not easy to operation, increase labor intensity, extend the time of remodeling.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of eave tile keyed roll lining fast replacing device remodeling quick and convenient, equipment cost is low.
The purpose of this utility model is achieved through the following technical solutions: eave tile keyed roll lining fast replacing device, including wallboard A, wallboard B, and roll unit, described roll unit includes roll mandrel and roll, axially opposing location is carried out by subdivision lining between said two roll, subdivision lining is set on roll mandrel, non-powered at roll mandrel is transmitted end and is had keyway vertically, keyway is built with gib head key, gib head key includes eave tile portion and slipping part, eave tile portion is arranged at one end of slipping part, the other end of slipping part stretches out wallboard A, top, eave tile portion is pressed in away from the roll end face of input gear, the non-powered transmission end of roll mandrel is connected by threaded engagement with locking nut, the other end of slipping part is locked by locking nut.
Further, described subdivision lining is two semicircle linings.
Further, the degree of depth of described keyway is more than the thickness of the slipping part of gib head key.
Further, described keyway is two, and two keyways are symmetricly set on the sidewall of roll mandrel, are separately installed with gib head key in each keyway.
Further, it is additionally provided with pad between described gib head key and locking nut.
Further, described pad is bowl-type pad, and the top, end of the slipping part of gib head key is pressed in the inner side of bowl-type pad.
This utility model has the advantage that
1, this utility model transmits two keyways of end milling in the non-powered of roll mandrel, in addition to the eave tile of gib head key end, remainder is hidden in axle, and two eave tiles exposed withstand on roll, and roll prolongs axially location, when needing to remodel, can unclamp nut in the outside of wallboard, lining is made split type structure, mobile two gib head keys i.e. can be taken off subdivision lining, again the subdivision lining of required size is contained between two rolls, whole remodel simple, convenient fast.
2, the slipping part of gib head key is hidden in axle, so the inner ring of bearing will not hinder the slip of gib head key, therefore need not increase bearing bore diameter and the thickness of bearing, the other end of slipping part stretches out wallboard, can tightening nut outside wallboard easily, so without increasing the width between two wallboards so that the production cost of equipment reduces.
