Description
Technical field
The invention belongs to Bar Cooling Bed tail portion compressed steel equipment technical field, it is related to a kind of Bar Cooling Bed tail portion compressed steel device
Using and its control method.
Background technique
During bar production, cold bed throws steel and always exists problem in production, when especially rolling small dimension, cold bed
The random steel phenomenon that often will appear " playing imperial steel ", the main reason for causing " playing imperial steel " random steel are because skirtboard throws the position of steel point
Variation causes rolled piece to prick head or hangs tail, latter steel is caused to knock into the back with previous steel.
Currently, operator is used first by skirtboard low level delay decrease (or lengthening) when this occurs, and allow
Skirtboard rapidly returns back to middle position；Either increase (or reduction) skirtboard buckle quantity, increases the measure that rolled piece is braked in rollgang
To solve the solution of cold bed unrest steel.But it is practical during production application, it is run after rolled piece finished product disjunction by rollgang
To cold bed region, the braking for realizing rolled piece with plate face frictional resistance is relied primarily on, rolled piece is then thrown into cold bed again, due to bar
In the effect of inertia of roller-way high-speed cruising, the rolled piece fallen on skirtboard also will continue to slide, it is easy to cause bar in cold bed
There is the buckling phenomenon of " playing imperial steel ", while it is irregular on cold bed and influence entire rhythm of production and big to also result in rolled piece
Increase reform through forced labor fatigue resistance.
Summary of the invention
In order to overcome the disadvantages mentioned above of the prior art, the present invention provide a kind of Bar Cooling Bed tail portion compressed steel device application and
The features such as its control method, it has structure simple, easy to make, easy for installation, easy to maintain；Using multiple spot, compressed steel is set
Control method, eliminate rolled piece tail portion on cold bed and the phenomena that " playing imperial steel " and head cannot be aligned occur, it is ensured that no
Multiple length rolled piece with length occurs tail portion buckling phenomenon in cold bed and the head position of rolled piece can be made to control in essentially identical position
It sets, is able to solve cold bed unrest steel problem, greatly reduces labor intensity.
The technical solution adopted by the present invention to solve the technical problems is: a kind of Bar Cooling Bed tail portion compressed steel device, including
Lever；Wherein lever one end is fixedly linked by presser bar and briquetting, and the other end then passes through drive rod and cylinder links, in lever
The support a positioned at lever bottom is then provided with by middle position.
The cylinder has piston rod, is connect by piston rod with drive rod；The other end of drive rod and the end of lever
It is connected.
The support a is fixedly linked by articulated manner and lever.
A kind of application of Bar Cooling Bed tail portion compressed steel device, applying step is:
On the skirtboard that rolled piece enters cold bed by rollgang high-speed motion, rolled piece is thrown in the tooth socket for falling into cold bed in skirtboard
When, by the effect of solenoid valve control actuating unit, rotate lever around the hinge contact of support a, the pressure on lever end
Block presses downwards, and is held down the rolled piece tail portion in movement, to increase the retro-speed of rolled piece, rolled piece is enable promptly to stop
Get off, prevents rolled piece from the buckling phenomenon of " playing imperial steel " occurs because sliding on cold bed.
A kind of control method of Bar Cooling Bed tail portion compressed steel device, rate-determining steps are:
According to the length of the setting of multiple lengths and cold bed, cut lengths, rolling line speed and the pass in cold bed minimum movements period
System, first with the related optimization function of finished product flying shear disjunction, according to the prediction length of blank, by the wherein several of every blank
Section multiple lengths are set as standard size, reduce the variation range of length of rolled piece, that is to say, when rolled piece finished product multiple lengths are less than
When the size of datum length is set, pressure tail is carried out using the compressed steel device of middle part pressure tail point；When rolled piece finished product multiple lengths are greater than
When the size of datum length is set, pressure tail is carried out using the compressed steel device of tail portion pressure tail point.
The positive effect of the present invention is: the features such as having structure simple, make, install and is easy to maintain, using multiple spot
The control method of compressed steel is set, eliminate rolled piece tail portion on cold bed occur " playing imperial steel " and head cannot be aligned it is various existing
As, it is ensured that the multiple length rolled piece of different length occurs tail portion buckling phenomenon in cold bed and the head position of rolled piece can be made to control basic
Identical position is able to solve cold bed unrest steel problem, greatly reduces labor intensity.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is operation schematic diagram of the present invention.
Fig. 3 is job control process principle figure of the present invention.
In figure: 1- briquetting, 2- presser bar, 3- support a, 4- lever, 5- support b, 6- drive rod, 7- cylinder.
Specific embodiment
Below with reference to embodiment, the present invention is further described.
Referring to Fig. 1, a kind of Bar Cooling Bed tail portion compressed steel device, including lever；Wherein lever one end passes through presser bar and pressure
Block is fixedly linked, and the other end then passes through drive rod and cylinder links, and is then provided with by middle position positioned at lever bottom in lever
The support a in portion.
The cylinder has piston rod, is connect by piston rod with drive rod；The other end of drive rod and the end of lever
It is connected.
The support a is fixedly linked by articulated manner and lever.
Referring to fig. 2, a kind of application of Bar Cooling Bed tail portion compressed steel device, applying step is:
