Abstract
The invention relates to a gib head key-type quick change device for a roller bushing. The gib head key-type quick change device comprises a wall plate A, a wall plate B and a roller unit, wherein the roller unit comprises a roller shaft, an input gear and rollers; the two rollers are axially oppositely positioned through partial bushing; the partial bushing sleeves the roller shaft; key grooves are formed at a non-powered transfer end of the roller shaft along the axial direction; gib head keys are arranged in the key grooves; each gib head key comprises a gib head part and a sliding part; each gib head part is arranged at one end of the corresponding sliding part; the other end of each sliding part extends out of the wall plate A; each gib head part props against the end surface of the roller shaft far away from the input gear; and the other end of each sliding part is locked by a locking nut. The gib head key-type quick change device has the advantages that the rollers are axially positioned through partial bushing and are locked by the gib head keys, so that the overall change operation is convenient, simple and fast; the operation space is reduced; and the production cost is reduced.
Description
Technical field
The present invention relates to cold roll forming milling train product size remodel fast technical field, particularly gib head key formula roll lining fast replacing device.
Background technology
During with cold roll forming mill milling section bar, difference according to requirements, can produce the identical and material (as: C section bar, U-shaped material etc.) that size is different of shape of cross section. If each size is all produced a milling train, not only cost is too high, and production site also can not meet the demands. Because the cross sectional shape of section bar is the same, can meet the demands by the lateral separation changing between roll, substitute many milling trains.
In order to achieve the above object, the common way of tradition has 2: the first increases the bearing bore diameter of back up roll axle and the thickness of bearing, fills an axle sleeve between roll mandrel and bearing, by this axle sleeve, roll is located vertically. Need to change the lining of roll time, unclamp nut, move or take off memorial archway, extract lining and roll. The shortcoming of the method is to cause whole equipment to strengthen because bearing strengthens, and cost just increases. And because bearing thickness increases, require the memorial archway frame thickening of dress bearing, so the method can not be used for wall board type milling train; It two is the width that increase wall board type milling train, thereby sets up two groups of locking nuts at roll two ends, while needing resleeve, unclamps two groups of nuts, after finishing changing, locks again. Its shortcoming is that milling train width strengthens, and weight and cost increase, and locking nut is in wallboard inner side, is not easy to operation, has increased labour intensity, has extended the time of remodeling.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, a kind of gib head key formula roll lining fast replacing device of remodeling quick and convenient, equipment cost is low is provided.
Object of the present invention is achieved through the following technical solutions: gib head key formula roll lining fast replacing device, comprise wallboard A, wallboard B, with roll unit, described roll unit comprises roll mandrel and roll, between described two rolls, carry out axial relative positioning by subdivision lining, subdivision lining is set on roll mandrel, non-power transmission end at roll mandrel has keyway vertically, gib head key is housed in keyway, gib head key comprises 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, eave tile portion top is pressed on the roll end face away from input gear, the non-power transmission end of roll mandrel is connected by threaded engagement with locking nut, locking nut is locked the other end of slipping part.
Further, described subdivision lining is two semicircle linings.
Further, the degree of depth of described keyway is greater 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, in each keyway, are separately installed with gib head key.
Further, between described gib head key and locking nut, be also provided with pad.
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.
The present invention has the following advantages:
1, the present invention transmits two keyways of end milling at the non-power of roll mandrel, except the eave tile of gib head key end, remainder is hidden in axle, and two eave tiles that expose withstand on roll, and roll is prolonged to axial location, need to remodel time, nut can be unclamped in outside at wallboard, and lining is made to split type structure, and mobile two gib head keys can take out subdivision lining, again the subdivision lining of required size is contained between two rolls, whole remodel simple, convenient quick.
2, the slipping part of gib head key is hidden in axle, so the inner ring of bearing can not hinder the slip of gib head key, therefore do not need to increase the thickness of bearing bore diameter and bearing, the other end of slipping part stretches out wallboard, tightening nut outside wallboard easily, so without the width increasing between two wallboards, the production cost of equipment is reduced.
