Description
Technical field
The slide calliper rule measured during a kind of angle steel rolling are the utility model is related to, belong to steel rolling survey tool technology neck
Domain.
Background technology
Big molded line milling train is by the reversible roughing mill of two frame dual roll types, a frame dual roll type reversing finishing mill and a frame dual roll type finished product
Milling train forms, and production model is the de- head rolling of single branch.
During angle steel rolling, with the accumulation of rolling time, due to caused by roll wear and guide and guards loosening
The change of finished product cross dimensions needs to adjust roll gap and guide and guard in time by quality work, so as to fulfill the stabilization of finished size.Usually
Means be using finished product sampling and measuring data as according to carrying out adjustment of rolling mill, but rolling pass is more and de- head rolling determines
The cycle length of finished product sampling, about 20 minutes, production efficiency is seriously reduced if being sampled by root, if growing in sampling interval time
Easily batch occurs since cross dimensions does not conform to the waste product of generation.
During angle steel rolling, single de- head rolling of branch causes finished product length to grow, and reversible rolling causes horizontal in the operation of rolling
It is more to move number.2 points of the above causes single branch angle steel side width fluctuations larger, and finished product sampling can only grasp local size, to whole
, easily there is the waste product that local angle steel hem width degree does not conform to generation in branch angle steel hem width degree monitoring deficiency.
Due to currently without the instrument measured in the operation of rolling to hot angle steel, have impact on real-time in the operation of rolling
Measurement, it is quite necessary to developed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of angle steel heat slide calliper rule, and this heat slide calliper rule can be quick
Angle steel rolling finished product hem width degree hot size is measured, improves production efficiency, is reduced because of batch and the off size generation of local section
Waste product.
Solving the technical solution of above-mentioned technical problem is：
A kind of angle steel heat slide calliper rule, it is made of blade, handle, measurement foot bar, fixed foot bar, and blade and handle are respectively
Stock, the rear end of blade are connected with the front end of handle, and point-blank, fixed foot bar is vertically connected on ruler for blade and handle
The front end of body, measurement foot bar are vertically connected on the rear portion of blade, fix foot bar and measurement foot bar in the same plane, and in blade
The same side, measuring the lower end of foot bar has a right angle ladder, and right angle ladder is opposite with fixed foot bar, and right angle ladder is measurement bayonet.
The distance between above-mentioned angle steel heat slide calliper rule, the measurement foot bar two planes opposite with fixed foot bar and angle steel
The lower limit of side width dimensions is corresponding, the distance between measurement foot bar lower end right angle ladder two planes opposite with fixed foot bar
It is corresponding with the upper limit of angle steel side width dimensions.
The beneficial effects of the utility model are：
The measurement foot bar of the utility model and fixed foot bar are stuck in the both sides on angle steel side, compare angle steel hem width degree respectively
The distance between foot bar plane is relatively fixed with measurement foot bar plane, right angle ladder plane, angle steel hem width can be quickly detected
Whether degree is qualified.The utility model is simple in structure, easy to use, measurement is accurate, low manufacture cost, is improving angle steel quality testing
While efficiency, the waste product because of batch and the off size generation of local section can be reduced, significantly improves the economic effect of enterprise
Benefit.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram for measuring foot bar；
Fig. 3 is the use state diagram of the utility model.
Marked in figure as follows：Blade 1, handle 2, measurement foot bar 3, fixed foot bar 4, right angle ladder 5, chock 6, angle steel 7.
Embodiment
The utility model is made of blade 1, handle 2, measurement foot bar 3, fixed foot bar 4.
Shown in figure, blade 1 and handle 2 are respectively stock, and the rear end of blade 1 is connected with the front end of handle 2, blade 1
With handle 2 point-blank.
Shown in figure, fixed foot bar 4 is vertically connected on the front end of blade 1, after measurement foot bar 3 is vertically connected on blade 1
Portion, fixes foot bar 4 and measurement foot bar 3 in the same plane, and in the same side of blade 1.In actual fabrication, blade 1, measurement
Foot bar 3 and fixed foot bar 4 are made by heat-resisting steel sheet and plate, can tailor processing by one block of steel plate.
Shown in figure, handle 2 makes for seamless steel pipe, and there is chock 6 in the rear end of blade 1, and chock 6 is inserted into the steel of handle 2
In pore, firm welding.
Shown in figure, there is right angle ladder 5 in the lower end of measurement foot bar 3, and right angle ladder 5 is opposite with fixed foot bar 4, right angle ladder
5 be measurement bayonet.
Shown in figure, the distance between measurement foot bar 3 two planes opposite with fixed foot bar 4 and angle steel side width dimensions
Lower limit it is corresponding, whether the width for measuring angle steel side is less than defined minimum dimension；Meanwhile it is straight to measure 3 lower end of foot bar
The distance between two planes opposite with fixed foot bar 4 of angle ladder 5 are corresponding with the upper limit of angle steel side width dimensions, for surveying
Whether the width of angulation steel 7 is more than defined full-size.
Shown in figure, the distance between measurement foot bar 3 two planes opposite with fixed foot bar 4 are a1, right angle ladder 5 with
The distance between two opposite planes of fixed foot bar 4 a2, they correspond to the minimum of the angle steel hem width degree of measured angle steel 7 respectively
Value and maximum.
Calculate a1 、a2, by taking the angle steel of a standard as an example, nominal hem width degree is a, the maximum of the hem width degree in execution standard
Plus tolerance is δmax, the absolute value of minimum negative common difference is δmin, coefficient of thermal expansion β, calculation formula is：
a1=(a-δmin) × β+(0.1~0.3),
a2=(a+δmax) × β-(0.1~0.3).
, be by the kind and execution standard design slide calliper rule quantity of angle steel, below 25# in actual fabrication（Containing 25#）Angle steel
Each kind has 3 kinds of execution standards, therefore each kind has 3 kinds of slide calliper rule, more than 25#（Without 25#）The each kind of angle steel has a kind to hold
Rower is accurate, therefore each kind has a kind of slide calliper rule.
The use process of the utility model is as follows：
In production process, after finished product rolled piece comes to a complete stop on roller-way, angle steel heat slide calliper rule handle 2 is held, makes consolidating for blade 1
Scale bar 4 and end in contact outside angle steel side are firm, the side keeping parallelism for keeping blade 1 to be measured with angle steel 7, at this time by contrasting angle
The apex angle of steel 7 and the relative position of measurement foot bar 3, share 3 kinds of situations：
If angle steel hem width degree is less than a1Or more than a2, then show that angle steel hem width degree is unqualified；
If angle steel hem width degree is between a1 、a2Between, then surface angle steel hem width degree is qualified, at this moment also to visually inspect slide calliper rule
Placement angle, need quality work to be adjusted if placement angle is excessive or too small, be detected again after adjustment.
