Description
Technical field
The utility model is related to the roll on a kind of milling train, more particularly, to the roll on a kind of new short cone milling train.
Background technology
Roll is the instrument for making steel produce plastic deformation, is the important component for determining rolling mill efficiency and mill bar quality, profit
The pressure that is produced when being rolled with one-to-one group of roll rolls stone roller steel, and existing roll uses monolithic construction.With roll field
Manufacturing technology continue to develop, traditional integral type roll has disadvantages that, it is impossible to solve quick-replaceable between different product
Problem, integral type roll in use, if crackle occurs in roll, needs whole replacings, and different product is rolled
Internal diameter is different, so needing many customization rolls, cost height, production cycle length, difficulty of processing are big.
Existing roll is the integral structure used mostly, and the split type roll for the changeable type having on the market is to use collars
It is to be fixed by thrust step between collars and roll shaft, thrust step can only prevent collars from being altered to a direction with roll shaft composition
It is dynamic, relative rotation occurs between collars and roll shaft in the operation of rolling.Changeable section plate spring is that leaf spring is light-weighted main
Development trend, short cone milling train is to manufacture one of capital equipment of changeable section plate spring.With reference to actual conditions to short cone milling train topping roll
Optimize design.Former roll is changed to split type, very big reduction roll buying and use and maintenance cost by monolithic construction, carried
The high roll accuracy of manufacture.
The content of the invention
The technical problems to be solved in the utility model is：In order to solve the problem of existing roll is using monolithic construction,
Now provide the roll on a kind of new short cone milling train.
The utility model solves the technical scheme that its technical problem used：
A kind of roll on new short cone milling train, including roll mandrel, fastener, collars, roll alloy sheath, round nut,
Fastener is provided with the middle of square key, described roll mandrel, described fastener outer surface is evenly distributed with 3 identical keyway П；
Described fastener outer surface is cased with roll alloy sheath；Described roll alloy sheath inner surface is evenly distributed with 3 identical keys
Groove；Described keyway and keyway П sizes is completely the same, and described keyway and keyway П keyway mouthful are completely superposed composition side
Shape keyway；Square key is distributed with described square keyway；The two ends of described fastener are respectively equipped with collars；Described collars table
Face is respectively equipped with 2 round nuts.
Further improved to be, the overall diameter of described fastener is slightly less than the interior diameter of roll alloy sheath.
Further improved to be, the height h of described fastener is equal to the height H of roll alloy sheath.
Further improved to be, described square key length L is equal to the height H of roll alloy sheath.
It is further improved to be, the overall diameter and roll alloy sheath of the overall diameter of described round nut between fastener
Between overall diameter.
The beneficial effects of the utility model are：1）Convenient disassembly, original design is monoblock type, once roll wear, is repaired, more
Change, process etc. and bringing great inconvenience.This design is conveniently replaceable, dismounting, easy to use；2）Save material, reduction use and maintenance
Cost, the split type roll structure that the utility model is provided only needs to change central roll alloy sheath, behaviour after scrapping using abrasion
Facilitate, 10% of use cost less than original structure.
