Description
Technical field
The invention belongs to field of metallurgy, relate to the scrap cutter gap correct measurement device of a kind of circle shear.
Background technology
Rotary shear equipment is one of visual plant of medium plate mill's finishing line, mainly carries out together steel plate length direction is bilateral
Time shear, make steel plate width reach dimensional requirement.Circle shear is by circle shear main body (including mobile side and fixing side) and scrap cutter
Main body (including mobile side and fixing side) two part composition.Circle shear main body is to be sheared by steel plate edge unnecessary for steel plate,
And the limit silk (length is at 6 m-25 m) after shearing is directed into scrap cutter by chute, by scrap cutter by limit silk simultaneous break
Becoming minor face silk (long 250 mm), minor face silk is by transporting device output.Circle shear is sheared steel plate thickness and is cut at 6mm-25mm, scrap cutter
Sword gap is generally 0.1 steel plate thickness, if blade clearance is not adjusted according to steel plate thickness, then easily causes cutting edge mouth and damages
Bad, cutting edge loosens, cutting edge falls, cutter head damages, causes limit silk to beat constantly to occur edge, long limit silk, steel plate edge to waft the fault such as bent,
Increase potential safety hazard, so correctly to adjust meaning the biggest in scrap cutter gap simultaneously.
Former scrap cutter is sheared and operation principle is as follows:
Such as Fig. 1, shown in scrap cutter clearance measurement structure chart: limit silk enter into scrap cutter top cutter 4 and scrap cutter bottom knife 5 it
Between, this axle of cutter shaft 3(on scrap cutter can only rotate and not be axially movable) and scrap cutter under this axle of cutter shaft 6(rotatably can be axial
Mobile, axial displacement is-10mm to 10mm) drive upper 4 times scrap cutter blade opposite side silks to shear respectively.Shear different steel
During thickness of slab angle value, the gap a(scrap cutter gap blade between scrap cutter top cutter and scrap cutter bottom knife) it is intended to rooting according to steel
Plate thickness is adjusted, and general a=0.1 steel plate is thick.
The numerical value of a value can be adjusted by two directions and reach, and on the one hand manually adjusts: adjusts backing plate by adjusting upper scrap cutter
The thickness of 7 times scrap cutter adjustment backing plates 8 reaches the change of a value；
The electronic adjustment of other direction: can reach gap change by gap increase or minimizing at operating board, principle is for pressing adjustment button
Time, lash adjusting device can drive cutter shaft 6 under scrap cutter to move axially, so that scrap cutter blade angle changes makes a value
Change, this change is recorded by sensor in Fig. 11, and this numerical value is converted to gap width between blade by trigonometric function by shift value；
Such as Fig. 4, in operating board computer display a value and Fig. 1, a value is same numerical value, a value (gap blade actual value)=sensor
Measured value+timing signal numerical value (operative employee with clearance gauge measure scrap cutter gap blade income value, upper scrap cutter adjust backing plate 7 or under
After scrap cutter adjusts the change of backing plate 8 thickness, this numerical value must heavily be marked)；Owing to a value is relevant with scrap cutter plate thickness, so a value
Cannot function as the soft position limitation protection value of the axial displacement of cutter shaft 6 under scrap cutter, measured and spacing by Fig. 1 intermediate gap time original design
The mechanical stop limiter of device 1 is protected, and spacing principle is as shown in Figure 2.
In Fig. 2, original design clearance measurement and stopping means 1.Blade electronic gap changing value, this value is measured by sensor 11
It is converted into gap blade changing value by trigonometric function；When the first block 13 encounters the first proximity switch 12, small-gap suture limits
Position puts in place, and gap can not be toward ditty, and the first block allowable displacement is 10mm；When the second block 14 encounters the second proximity switch 15
Time, wide arc gap is spacing to put in place, and gap can not be adjusted toward big, and the second block 14 allowable displacement is 10mm.First block, the second block
Allow axial displacement only have 10 mm, owing to displacement is the least, proximity switch sensitivity is the poorest, cause spacing the most just
Really, occurring that spacing opening causes the stuck gap that cannot be carried out of lash adjusting device to adjust, still there is surplus in gap sometimes, but due to limit
Position puts in place and cannot be carried out adjusting；Mechanical stop limiter in above reason clearance measurement and stopping means 1 cannot play protection at all
Effect, so having a strong impact on the correct adjustment of gap blade.
Correct protective effect can not be played owing to gap blade is spacing, make gap blade to be correctly adjusted, institute
Shear through conventional same gap width during to produce, cause a series of fault.

Detailed description of the invention
The scrap cutter gap correct measurement device of a kind of circle shear, Fig. 2-1 is the structural representation of the present invention.Fig. 2-2 is
Scrap cutter blade and the structural representation of adjustment backing plate in the present invention.Fig. 3 is the connection diagram of the second sensor in the present invention.
This device includes for measuring scrap cutter top cutter 4 and the first sensor 11 in scrap cutter bottom knife 5 gap, for measuring broken limit
Cut the second sensor 21 of the axial shift value of cutter shaft 6.First sensor is connected with cutter shaft under scrap cutter；Second sensor passes through
Fixing lid 22 is fixed on to protect to be put on 29；By the magnet ring 24 of the second sensor measurement position by copper packing 23 and copper sheathing 25 and surrounding
Every magnetic, and fixed under scrap cutter on cutter shaft by gland 28 and fixed mount 26, and magnet ring follow under scrap cutter cutter shaft to the left or to
The right side is synchronized with the movement.
In Fig. 4, operating board computer display numerical value a, a value=blade actual gap value=manually adjust value+electronic adjusted value=mark
Regularly numerical value+first sensor measured value；Timing signal numerical value is the reality that scrap cutter gap blade gained measured by operative employee's clearance gauge
Measured value；First sensor measured value is from demarcating to changing value now.
Cutter shaft position=the second measurement value sensor under operating board computer display numerical value b, b value=scrap cutter；This measurement apparatus
The position at any time of cutter shaft under actual measurement scrap cutter, plays position limitation protection when cutter shaft is axially adjustable under scrap cutter and gap adjusts surplus ginseng
Examine effect.
In Fig. 2, when installing for the first time, the second transducer zeroing is demarcated, the excursion of b value be-10mm arrive+
10mm；This value is in Fig. 1, the actual displacement value of lower scrap cutter cutter shaft, the maximum of b value and minimum spacing limit；When reaching
During minimum spacing-10mm, under scrap cutter, cutter shaft can not be toward moving left, and scrap cutter gap can not be toward ditty；On the contrary when reaching maximum limit
During+the 10mm of position, under scrap cutter, cutter shaft can not be toward moving right, and scrap cutter gap can not be adjusted toward big；Second sensor surveyed numerical value b number
Value is correct, linear change and lower scrap scissors shaft position one_to_one corresponding, serve the tram to scrap cutter cutter shaft determine and
Position-limiting action.When b value, to reach minimax spacing, and when a value is not reaching to require, it is impossible to by cutter shaft under electronic adjustment scrap cutter
Axial displacement and can only by adjust scrap cutter plate thickness make gap blade a value reach needs.So a value plays gap reality
Shear action, b value plays cutter shaft position-limiting action under scrap cutter.
The present invention removes the first proximity switch in original device, the first block, the second proximity switch and the second block, i.e. goes
Remove position-limiting action part, retain first sensor part.
In the diagram, in the numerical value of operating board computer display scrap cutter gap, increase b value (lower cutter shaft positional value) display, install
Time b value carried out 0 demarcation (adjust tooth to casing spacing be 10mm time, be demarcated as 0), and b value is carried out soft from program
Spacing setting, the excursion of b value is-10mm to+10mm, makes the axial displacement of cutter shaft under scrap cutter play correct protection.
After improvement, when reaching the adjustment of scrap cutter gap by the axial displacement of cutter shaft under electronic adjustment scrap cutter, minimax
The soft spacing of spacing value serves correct protection reliably, never occurs that scrap cutter adjusts tooth and exceeds spacing and occur that axle is stuck
Cannot adjust the fault in gap, it is relieved audaciously according to steel plate thickness electronic adjustment scrap cutter gap that this significantly facilitates operative employee.
In the past due to scrap cutter gap can not correct electronic adjustment, easily occur stuck, so often making during electronic adjustment
Shear steel plate and thin specification steel plate with same gap width, make scrap cutter cutting edge be easy to damage.Scrap cutter gap is according to steel plate
After thickness can be adjusted, scrap cutter cutting edge is protected, and shears steel plate and thin specification steel plate (6-7mm) Shi Biansi can be complete
Portion interrupts, and cutting edge abrasion is little and fixes and is not easy to loosen.Scrap cutter cutting edge has extended to 2 from original 15 days service life
Individual month；Scrap cutter blade is not easy to loosen, and former per tour must once tighten up, and is now made without tightening up；Reason is in blade
Loosening and cause cutter head side and silk tooth to damage, within every 3 months, must pull down cutter head and repair, existing cutter head uses never to go out for 1 year
Now damage, so being greatly saved spare part expense.During former shearing 6-7mm steel plate, limit silk is often beaten constantly, easily occur edge or
The long limit silk problem of more than 10 meter long, causes batch 6-7mm steel plate edge to waft song, and need to shut down process edge or cut long limit with gas cutting
Silk, increases security risk.
This invention ensures that steel plate shearing quality of edges, decrease and ensure that production is carried out continuously, and decreases downtime
Labor strength, decrease spare part expense, decrease potential safety hazard.
