Abstract
The utility model discloses a ladder pad for rolling mill, including the ladder advance capital for body, the ladder advance capital for body includes the ladder level that descends step by step, wherein: two adjacent ladder level differences in height are the same, are provided with circular -arc slag runner between the adjacent ladder level, through the slag runner that the aforesaid set up, can in time discharge the residue of dust in the environment and processing at the during operation, avoid piling up on ladder level plane, influences stable connection the between ladder level and the supporting shoe, and especially in adverse circumstances, dust and the production of incomplete bits are more, too much pile up the damage that can cause equipment, and when grinding flat ladder level plane, can directly move back the sword with the slag runner, processing property is better.
Description
Technical field
The utility model relates to a kind of mechanical fitting, and more particularly, it relates to a kind of milling train step pad.
Background technology
In integrated iron and steel works, there is various milling train, mainly hot rolling, cold rolling, heavy plate mill etc., and in often kind of milling train, all have employed Hydraulic Pressing-down Cylinder, be commonly called as AGC oil cylinder.This oil cylinder plays automatic thickness and controls in milling train, and directly affecting the quality of steel plate, is the vitals of milling train.Step pad is located on AGC oil cylinder working-pressure plate, and the diameter because of roll during replacing roll is different, by the driving of driver part, step pad is moved to corresponding progression to ensure the height of roll line.
At present, application number is that the Chinese patent of CN201020272269.2 discloses a kind of rolling horizontal line adjusting device of heavy plate mill, this adjusting device comprises the step pad be located on AGC oil cylinder working-pressure plate, be located at the driver part of step pad side and the back-up block under being fixed on lower backing roll bearing block, described back-up block upper end is plane, the centre of lower end and both sides are equipped with a projection for supporting, three projections offset with the upper surface of step pad corresponding stage respectively, although this horizontal line adjusting device effectively can increase contact width between back-up block and step pad and contact area, improve stability, but in use, granulated slag is not easy to discharge on stepped plate, granulated slag easily affects the switching performance between back-up block and stepped plate.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the milling train step pad providing a kind of deslagging good.
For achieving the above object, the utility model provides following technical scheme: a kind of milling train step pad, comprises step pad body, and described step pad body comprises the gradin declined step by step, wherein: adjacent two gradin differences in height are identical, are provided with the ash pit of arc-shaped between adjacent steps level.
By adopting technique scheme, by being provided with ash pit, can operationally discharge by the timely residue by the dust in environment and processing, avoid being deposited in gradin plane, to affect between gradin with back-up block stable is connected, especially, in adverse circumstances, dust and detritus produce more, and too much accumulation can cause the damage of equipment; And when polishing gradin plane, directly can apply ash pit and carry out withdrawing, processing characteristics is better.
The utility model is set to further: described ash pit is provided with chamfering in higher-order step side.
The utility model is set to further: the radius of described chamfering is 3mm.
The utility model is set to further: the angle of described chamfering is 45 °.
By adopting technique scheme, arranging of chamfering can when shifting back-up block, and back-up block can move stably on gradin, avoids wedge angle to contact with back-up block, causes damage to back-up block, also can regulate more easily simultaneously.
The utility model is set to further: described step pad body comprises the connecting hole being arranged on four angles, and described connecting hole is set to countersunk head screwed hole.
By adopting technique scheme, because step pad quality is larger, when mobile, need the attachment screw of movement machinery to be connected into step pad body, connect at four angles, ensure that closely stable being connected on corresponding equipment of step pad body is moved, and adopt countersunk head screwed hole can ensure connect time and attachment screw can connect into connecting hole fully, and conflict with the sidewall of countersunk head, reduce to the pressure owing to rocking double thread generation in moving process, thus ensure that the stability of structure.
The utility model is set to further: described step pad body adopts alloy steel material to make.
By adopting technique scheme, 50CrNiMoV material is adopted to have good mechanical property, wear-resistant, ensure that the serviceability of step pad, improve service life.
The utility model is set to further: the described ash pit degree of depth is less than 1mm, and the arc radius of described ash pit is 10mm.
By adopting technique scheme, the ash pit degree of depth is less, thus steadily can enter ash pit when residue chip falls into, and can not rebound out, and have certain depth, and the material in groove can not turn back in gradin plane.
