Description
Invention field
The invention belongs to mechanical engineering technical field, relate to a kind of long material movable scale machine.
Background technology
The shearing rolled piece of cold flying shear is sent to clipped position by feeding roller-way, each rolled piece in same group, not quite identical with the contact friction force of feeding roller, and when causing the rolled piece of same group to advance to shearing scale position, the length of rolled piece in one group is inconsistent.Compare with fixedly cutting, cold flying shear have employed the technique that motion is sheared, and do not have the fixed ruler baffle fixedly cut, although improve shear efficiency, same group of length of rolled piece there are differences, and have impact on end product quality.
Up to now, the way that cold flying shear addresses this problem one installs hold-down roller before flying shear is cut, increase the frictional force of rolled piece and rollgang, another increases magnetic force roller-way after cutting before cutting, improve the adhesive force of roller-way conveying, these measures serve certain effect, if but workpiece diameter error, or when shearing screw-thread steel, the effect of these measures is all not obvious.
Therefore, the uneven state shearing rolled piece its end head before shearing waited by cold flying shear, is the problem that this field needs to solve.

Detailed description of the invention
Core of the present invention is the fixed ruler baffle arranging movement on the orbit waiting to shear rolled piece, treats the end head shearing rolled piece and moves pier together, solves the accumulated error treating that shearing rolled piece is advanced on rollgang, shearing finished product length is consistent.
The present invention is arranged on cold flying shear production line outlet roller-way side, and movable scale chassis (3), according to different sheared length specifications, is fixed on the precalculated position of movable scale machine support stand (1).
Not identical with the frictional force of roller-way owing to waiting to shear each rolled piece, after rolled piece runs a segment distance on roller-way there is uneven state in workpiece front end.Wait that shearing rolled piece moves to outlet roller-way place, supplied materials position-detection sensor is connected, and system starts to shear timing and sends instruction to flying shear body.Drive unit (3.2b) drive head sprocket wheel (3.2a) of electrical drive control system device (5) instruction annular drive chain (3.2) is simultaneously rotated, ring chain (3.2d) is driven to rotate, drive connected measuring head (3.3) prior to waiting that shearing rolled piece enters its orbit, because the average speed setting of measuring head (3.3) is less than the speed of service waiting to shear milling train, make to wait that shearing rolled piece pulls up to measuring head (3.3), first wherein advanced rolled piece can knock measuring head (3.3), speed is reduced to the identical speed of measuring head (3.3).Delayed treats that shearing rolled piece is not before touching measuring head (3.3), speed is greater than measuring head (3.3), finally can catch up with measuring head (3.3) and prior exposure and wait that shearing rolled piece becomes identical speed to measuring head (3.3), all wait that shearing rolled piece stops through the deceleration of fixed ruler baffle with group, end head is concordant state by pier together.
When measuring head (3.3) will after shearing rolled piece pier be neat, system supplied materials position-detection sensor connects timing, accumulative waiting shears rolled piece travel distance, before flying shear body shears rolled piece, measuring head (3.3) travels out to be waited to shear rolled piece orbit, decontrol the stop treated and shear rolled piece, flying shear body is pressed electrical drive control system device (5) instruction and is sheared rolled piece.
Measuring head (3.3) is decontroled after shearing rolled piece, to join mobile pier together in time shearing rolled piece next time, and need through after a while and run a segment distance with gypsy chain.Waited to shear the distance of rolled piece to Dun Qi district by system foundation during this period of time, calculate the speed that travels at the uniform speed of measuring head (3.3).
Shear in circulation at one, measuring head (3.3) need shear rolled piece end to end between enter and shear the track of advancing of rolled piece, therefore, the setting speed being in scale transfer roller-way (2) after movable scale chassis (3) is greater than cuts rear roller-way, and be greater than the speed of cutting front roller-way and approach table, after the workpiece front end after flying shear body is sheared is advanced through and cuts rear roller-way, with cut rear rolled piece afterbody and pulled open a segment distance, when this segment distance that this section pulls open walks to the porch of movable scale chassis (3), proximity switch on movable scale machine is connected, the moving stop of electrical drive control system device (5) instruction movable scale chassis (3) enters waits that shearing rolled piece advances track, start a new round and shear circulation.
The present invention is when changing setting and shearing cut lengths, need to retighten movable scale chassis (3) position, now the first embodiment movable scale chassis horizontal drive device (4) driving gear drives device (4.1a) rotates and engages with tooth bar (4.2a) and promotes movable scale chassis (3) and move to default position.Second embodiment head hoist engine (4.1) rotates and drives connection steel wire rope (4.3) to pull movable scale chassis (3) to default position.
