Description
Technical field
The utility model relates to technical field of metallurgical equipment, and in particular to a kind of scrap chopper gap zero-bit quickly adjusts
Device.
Background technique
Rotary shear equipment is one of important equipment of finishing line, and progress mainly bilateral to steel plate length direction is cut simultaneously
It cuts, so that steel plate width is reached dimension precision requirement, and synchronize broken side to the edge grinding after shearing and handle, be readily transported.Disk
It cuts and is made of circle shear main body (including mobile side and affixed side) and scrap cutter main body (including mobile side and affixed side) two parts.
Circle shear main body is to shear steel plate edge, and by the long edge grinding after shearing (for length in 6~25m, width is in 5~50mm)
It is directed into scrap cutter by chute, by scrap cutter by long edge grinding simultaneous break at short edge grinding (long 250mm), short edge grinding is by transporting
Device output.
High magnetic sensing cold milling orientation silicon steel, i.e. HiB steel, characteristic are that material is relatively thin, and thickness only has 0.15~0.35mm, material
It is brittle, while split depth, while wave it is high, these characteristics are very tight to the clearance requirement between upper lower scissor blade, and blade clearance and registration have
Stringent process matched therewith requirement.Gap varies slightly, it will cutting edge top knife (gap is less than zero) occurs or steel band cuts continuous (gap
Become larger) the phenomenon that.Scrap cutter blade clearance is generally 7% times of steel plate thickness, by taking the thin plate for shearing 0.3mm as an example, blade clearance
It need to be adjusted to 0.02~0.03mm.If shears blades space adjustment is improper, it be easy to cause the damage of cutting edge mouth, cutting edge to loosen, cutting edge
Fall, the failures such as cutter head damage, eventually cause that edge grinding beats emergence edge, the problems such as wave occur in long edge grinding, steel plate edge, together
Shi Zengjia security risk, thus the gap of scrap cutter correctly adjust and its required precision directly influence shearing unit produce into
Degree.
The gap adjustment of scrap cutter is to read the zero reference point that scrap cutter is arranged when leaving the factory by computer, according to this
Reference point and the strip thickness gauge sheared calculate scrap cutter gap, and feed back to sensor, and sensor guidance is connected to it
The movable cutting edge of screw rod rotation, screw rod and scrap chopper connects, and screw rod rotation can drive movable cutting edge transverse shifting, thus
Adjust the gap between upper and lower cutting edge.
However, since operation hours is beyond after the quality guarantee time limit, the transmission accuracy of scrap cutter reduction gearbox and distributor box because
There is error in abrasion, and scrap cutter gap adjusted actual value is bigger than computer adjusted value.For example, scrap cutter is in mechanical zero
Blade clearance should be 0.01mm, and when such as shearing plate thickness is 0.30mm, according to the 7% of plate thickness adjustment, scrap cutter gap be should be
0.021mm.But it is found through measurement, in actual use, actual gap when scrap cutter gap is 0.021mm exists
Between 0.04mm-0.05mm, it is greater than required normal cutting edge gap, causes scrap cutter continuous.Scrap cutter is during running at high speed
Pullling edge grinding easily causes to produce steel plate main body wooden dipper song, scrap cutter swaging clamp, and scrap cutter serious wear directly results in scrap cutter cutting edge
Consumption it is excessive and production efficiency is low.Therefore it must be zeroed manually in precision shearing.There is essence in the adjustment device of the prior art
Spend the defect not reached requirement, it is difficult to realize the quick adjustment of zero-bit.
Utility model content
The technical problem to be solved by the present invention is in view of the deficiency of the prior art, provide a kind of broken side
Cutter gap zero-bit high-speed adjustment device, it restores accurate reading of the computer to zero-bit by the adjustment to zero-bit position-arresting disk
It takes, so that computer output scrap cutter gap adjustment is reached shearing ideal value, avoid the occurrence of the phenomenon that scrap cutter pulls edge grinding, thus
The generation for phenomena such as reducing steel-fastening, cutting edge abrasion, increases scrap cutter sword shearing displacement, production efficiency is promoted to improve, reduce consumption.
The utility model is technical solution used by solving technical problem set forth above are as follows:
A kind of scrap chopper gap zero-bit high-speed adjustment device, including set gradually from outside to inside fixed disk, limit
Disk and screw rod, the screw rod are radially equipped with the screw rod pointer of a protrusion, are equipped between the position-arresting disk and screw rod and are used for institute
The looping pit that screw rod pointer moves in a circle is stated, the position-arresting disk is equipped with zero value position and maximum limit place value position, described
The rotating range of screw rod pointer is to rotate from zero value position to maximum limit place value position；The position-arresting disk can fix disk relatively
It rotates freely, is realized between the two by fastener relatively fixed；There is scale in the fixed disk.
In above scheme, there are two the fasteners, and two fasteners are located at a certain radial phase of the fixed disk
To both ends.
In above scheme, the fastener is bolt, and the head of bolt is located at the outside of the fixed disk, the screw rod of bolt
It is contacted after passing radially through the fixed disk with the outer circle of the position-arresting disk.
In above scheme, the inner circle of the position-arresting disk is convex equipped with one between zero value position and maximum limit place value position
It rises, the protrusion plays position-limiting action to the rotation of the screw rod pointer.
In above scheme, if it is β that it, which rotates angle, when the screw rod process is 0.01mm, every the angle β in the fixed disk
Degree designs a scale, i.e., shares 360/ β scale in the described fixed disk.
In above scheme, the scale is printed on the surface of the fixed disk.
In above scheme, the surface of the fixed disk is fixedly installed with dial, and the scale is printed on the scale dish cart
Face.
The utility model has the beneficial effects that:
1. the utility model can be by any angle zero adjustment be realized, by fixed disk radially phase needed for production
Position-arresting disk is fixed in one group of bolt of installation, realizes freely adjusting for position-arresting disk.Scale is set in fixed disk simultaneously, is made
Fixed disk can not only prevent the outside play of position-arresting disk, can also realize the quick adjustment to zero-bit, while can be to computer
Adjustment gap width does a calibration.It is advantageous to realize the fast quick-recovery in scrap cutter zero-bit gap, keep scrap cutter shearing edge grinding gap
In ideal value, reduces because of edge grinding steel-fastening machine stop times, improve operating rate.
2. the phenomenon that the utility model can eliminate scrap cutter because gap is excessive, cut continuous edge grinding, and pull edge grinding reduces hair
Thorn, flash generate, and avoid changing ruler because there is the defect, improve coil of strip lumber recovery.
3. the utility model can accurately harmonize the gap of scrap chopper, scrap cutter cutting edge service life is significantly increased,
Reduce spare parts consumption.
4. utility model device structure is simple, acquisition can be transformed in prior-art devices, transformation is simple, at
This is cheap, easy to use, is conducive to maintenance, can be fully solved broken side gap because computer caused by origin distortion and actual gap are different
The phenomenon that cause, is also applied in the orientation silicon steel even cropping cut operation of other thin gauge materials.
