Description
Technical field
The invention belongs to cold shears field, it is related to a kind of reinforced cold shears frame, and in particular to a kind of long product rolling row
The reinforcing mortise and tenon frame of industry completed product shearing machine.
Background technology
All finished product cold shearses of steel mill, in order to improve the shear ability of equipment, just influence shear ability most both at home and abroad at present
Direct body frame part generally all takes the size of amplification stress frame, increases thickness of slab and improves level weld seam requirement and quality
To solve.But with steel mill's product specification extension and the huge increasing of yield, the disposal ability of existing line configuration finished product cold shears is all
State unable to do what one wishes is shown, such as substantial amounts of special steel rolling line cold shears machine equipment couples body due to bearing huge strong shock loading
Portion loosens, strength weld strain cracking, causes device damage to fail and scrap.
Generally, in the finished product shearing equipment for rolling long material, the manufacture method of cold shears frame and its structure type are a variety of more
Sample, often names Type of equipment with the structural shape of frame.C-opening formula such as existing 150 tons~650 tons medium and small tonnages is cold
Cut, the gantry type frame cold shears of remaining silent of 850 tons~1300 tons of the large-tonnage still developed in recent years.Their title custom
Disaggregated classification is distinguished as 1 using mostly important primary structure member mainframe；C-opening formula casts frame cold shears (lateral open
Formula) .2；The welded steel structured rack cold shears of c-opening formula group (lateral open formula)；3；The welded steel structured frame of gantry closed type group
Formula cold shears (laterally close formula).
For 150 tons~650 tons c-opening formulas casting frame cold shears (lateral open formula) of medium and small tonnage, by
In such frame blank be usually using monoblock cast, therefore blank production cycle length, process not environmentally, manufacturing cost it is high plus
Work is more difficult and the production cycle is long, sees that frame is in side opening shape importing and exporting side, frame waist subjects huge when shearing machine works
Moment of flexure, and frame body by produced after shearing force larger elastic dilatation, opening degree deform, be unfavorable for shearing machine and normally run,
Therefore the type is not suitable for the use of large-tonnage cold shears；
Come for 150 tons~650 tons welded steel structured frame cold shearses of c-opening formula group (lateral open formula) of medium and small tonnage
Say, because the frame blank is using steel plate welding manufacture, there is that welding capacity is big to require that high, frame weight is big, manufacturing process
Multicycle is long, and same frame is in side opening shape, and when shearing machine works, frame waist is also subjected to huge moment of flexure, and frame body
The elastic deformation larger by upper lower slide opposite direction is produced after shearing force, is unfavorable for shearing machine and normally runs, therefore the type is same
The cold shears for being unsuitable for super-tonnage is used；
For frame cold shears (closed type) welded steel structured for 850 tons~1300 tons of planer-type groups, due to the frame
Blank docks manufacture using steel plate downhand welding, therefore there is welding front spring groove section and require high, be particularly lower slide cage bar
With the vertical downhand weld of machine frame at two sides, often need large-tonnage to impact working condition when shearing special steel, exceed welded section at this
The load force value that intensity can bear, first produces fine cracks, afterwards constantly slowly from weak links such as its defect, stress raisers
Become big elongated, final main stress steel plate leg often in cracking shape connection separation failure, causes device damage to shut down；In addition,
The frame top is in hatch frame without pin, and it is coupled closing using bolt with front panel, be it is uncontrollable constrain knife rest, guide rail by
Deflection after power, causes active service upper tool post cutting edge movement clearance and changes generation drift, directly affect finished product shearing quality.Separately
Its outer transmission system drives main crankshaft with two-stage enclosed helical gear, and the axial thrust load produced by shearing must be on end plate
Conjunction bolt is born, under repeated stock, shock effect, conjunction bolt connection loosening is usually occurred, disengaged by end plate, causes to cut
Cut portion's integral rigidity, intensity to be deteriorated, until shutting down and playing its periphery reinforcement plate angle hoop by being welded integral processing.
The content of the invention
