Description
Technical field
The present invention relates to the control method of hook type tilter.
Background technology
For realizing in the blooming mill operation of rolling according to rolling schedule automatic turning rolled piece.Each installation finer tilt mechanism on transmission side manipulator before blooming mill machine and after machine.It is after front a time terminates that tilting gear is used for turning over steel, milling train without when rolling load by rolled piece around its longitudinal axis half-twist.6 tilting fingers of every platform tilting gear carry out transmission by a squirrel cage motor by the crank device being furnished with worm gearing.
The control mode of domestic existing blooming mill hook type tilter has following two kinds:
1, when blank is square billet, calculate according to the translational speed of tilting finger and the altimeter of rolled piece tilting finger to rise to upper surface time t from rolled piece lower surface, then calculate manipulator moves rolled piece width distance speed v in the t time.When tilting finger turns over steel, time delay 200ms starts transmission side manipulator and composes movement speed v.
2, when blank is for circle base, when front several passage turns over steel, because rolled piece side is cambered surface, uses tilting finger to turn over steel and easily cause and turn over steel slippage, and adopt the auxiliary tilting gear of band pinch roll to turn over steel.
Above 2 kinds of control mode Problems existing: the height h of rolled piece is less than the width b of rolled piece when turning over steel, due to factors such as motor acceleration, when tilting finger reaches rolled piece upper surface, manipulator displacement is less than b/2, easily causes and turns over steel failure; And adopt the auxiliary tilting gear of band pinch roll to turn over steel, it is long to turn over steel process, influence of rolled rhythm.
Summary of the invention
Technical problem to be solved by this invention realizes one to avoid when front 1 ~ 2 passage turns over steel, due to rolled piece side be cambered surface cause turn over steel failure, and the control method of rolling cycle can be shortened.
To achieve these goals, the technical solution used in the present invention is: control method for hook type tilter, and system gives rolled piece width value b, rolled piece height value h and manipulator gap width d, and according to following steps work;
Rolled piece moves to and turns over steel position by step 1, fore side manipulator and transmission side manipulator, and fore side manipulator is return afterwards, shifts out and turns over steel space, and distance is h+d;
Tilting finger on step 2, transmission side manipulator rises by under roller-way face, when touching rolled piece, starting transmission side manipulator and being carried out to fore side manipulator side by rolled piece;
After step 3, transmission side manipulator implementation distance reaches b, rolled piece moves to and newly rolls position, hole by fore side manipulator and transmission side manipulator, and after this passage terminates, tilting finger drops to original position.
Described rolled piece width value b, rolled piece height value h and manipulator gap width d are measured by front a time hook type tilter to give.
Bar rolling speed carried out by described transmission side manipulator is 35-300mm/s.
Described fore side manipulator is 35-300mm/s in independently moving hourly velocity, when jointly carrying out rolled piece with transmission side manipulator, and speed follower transmission side manipulator speed.
In described step 2, tilting finger touches speed before rolled piece is 70-90mm/s, and after touching rolled piece, speed is 320-380mm/s.
Operate fore side manipulator in described step 1 to shift out space length and be greater than h.
The present invention effectively can improve and turns over steel success rate, and improves operating efficiency, shortens the steel rolling cycle, in addition, also further increases the quality of product.

Detailed description of the invention
Control method for hook type tilter of the present invention controls according to the order of Fig. 1-6, specifically, carries out according to following steps:
Rolled piece 3 moves to and turns over steel position by step 1, fore side manipulator 1 and transmission side manipulator 2, fore side manipulator is return afterwards, shift out and turn over steel space, distance is h+d1, fore side manipulator 1 shifts out distance and is generally greater than rolled piece 3 height h, rolled piece 3 height value h and manipulator gap width d by front a time hook type tilter measurement imparting;
Tilting finger 4 on step 2, transmission side manipulator 2 rises by under roller-way face, the steel that turns over of tilting finger 4 waits for that position can be set in 50mm place under roller-way face, when touching rolled piece 3, start transmission side manipulator 2 rolled piece 3 is carried out to fore side manipulator 1 side, in addition, when detecting that tilting finger 4 arrives rolled piece 3 lower surface, tilting finger 4 is hooked up to transfer to by low speed and normally hooks up speed faster;
Step 3, transmission side manipulator 2 are carried out after distance reaches b, and rolled piece 3 moves to and newly rolls position, hole by fore side manipulator 1 and transmission side manipulator 2, and after this passage terminates, tilting finger 4 drops to original position.
Wherein, rolled piece width value b and rolled piece height value h and manipulator gap width d is measured by front a time hook type tilter to give.
Like this, when any passage carries out automatic turning steel, no matter rolled piece 3 section configuration, when tilting finger 4 turns over steel, transmission side manipulator 2 all will move the distance of a rolled piece 3 width b to rolled piece 3 direction.Even if tilting finger 4 is turning over slippage in steel process, transmission side manipulator 2 also can prop up rolled piece 4 in time, and by its righting, avoids and turn over steel failure.
The preference data of this control method: set tilting finger 4 start bit θ=320 °, rolled piece 3 lower surface position (acceleration position) θ=10 °, θ=95, upper deceleration position °, upper position of rest θ=155 °, θ=280 °, lower deceleration position before machine after tilting finger position functions block FC332 and machine in tilting finger position functions block FC382; Above-mentioned angle is the anglec of rotation that the pulse coder be arranged on the crank axle of worm gearing detects crank axle.Crank axle rotates a circle (360 °), and tilting finger completes and once turns over steel stroke.Angle defines: when upper surface and the roller-way of tilting finger is when neat, defining tilting finger angle is θ=0 °; When the upper surface of tilting finger overlaps with rolled piece lower surface, definition tilting finger angle is for accelerating θ=10 °, position; When the gib head indentation manipulator baffle plate of tilting finger, definition tilting finger angle is θ=95 °, upper deceleration position; When the upper surface of tilting finger reaches the peak of stroke, definition tilting finger angle is upper position of rest θ=155 °; When the gib head of tilting finger all stretches out manipulator baffle plate, definition tilting finger angle is θ=280 °, lower deceleration position; 50mm place under the upper surface distance roller-way face of tilting finger, definition tilting finger angle is start bit θ=320 °.
Rolled piece 3 speed carried out by transmission side manipulator 2 is 280-320mm/s, preferred 300mm/s, to move preferred 35mm/s before touching rolled piece 3 with 30-40mm/s, and after touching rolled piece 3, speed promotes.The speed of hooking up is 70-90mm/s, preferred 80mm/s, and the speed that normally hooks up is 320-380mm/s, preferred 350mm/s.Utilize above-mentioned data, more perfectly can complete and turn over steel operation.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
