Description
Technical field
The invention belongs to cold shears fields, are related to a kind of reinforced cold shears rack, and in particular to a kind of long product rolling row
The reinforcing mortise and tenon rack of industry completed product shearing machine.
Background technique
All finished product cold shears of steel mill just influence shear ability most to improve the shear ability of equipment both at home and abroad at present
Direct body frame part usually all takes the size of amplification stress rack, increases plate thickness and improves level weld seam requirement and quality
To solve.But with the huge increasing of steel mill's product specification extension and yield, the processing capacity of existing line configuration finished product cold shears is all
State unable to do what one wishes is shown, such as a large amount of special steel rolling line cold shears machine equipment couples body due to bearing huge strong shock loading
Portion's loosening, strength weld strain cracking, cause equipment damage to fail and scrap.
In general, the manufacturing method of cold shears rack and its structure type are a variety of more in the finished product shearing equipment for rolling long material
Sample often names Type of equipment with the structural shape of rack.C-opening formula such as existing 150 tons~650 tons medium and small tonnages is cold
It cuts, 850 tons~1300 tons of the large-tonnage still developed in recent years of silent gantry type frame cold shears.Their title habit
With mostly important primary structure member mainframe come distinguish disaggregated classification be 1；C-opening formula casts rack 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 rack of gantry closed type group
Formula cold shears (laterally close formula).
For 150 tons~650 tons c-opening formulas of medium and small tonnage casting rack cold shears (lateral open formula), by
Be usually used monoblock cast in such frame blank, thus the blank production cycle is long, process not environmentally, manufacturing cost it is high plus
Work is more difficult and the production cycle is long, sees rack in side opening shape in inlet and outlet side, rack waist subjects huge in shearing machine work
Moment of flexure, and frame body generates biggish elastic dilatation, opening degree deformation after by shearing force, be unfavorable for shearing machine normal operation,
Therefore the type is not suitable for the use of large-tonnage cold shears；
150 tons~650 tons welded steel structured rack cold shears of c-opening formula group (lateral open formula) of medium and small tonnage are come
It says, since the frame blank is using steel plate welding manufacture, there are the big requirement height of welding capacity, rack weight greatly, manufacturing process
Multicycle is long, and same rack is in side opening shape, and in shearing machine work, rack waist is also subjected to huge moment of flexure, and frame body
The upper biggish flexible deformation of lower slide opposite direction is generated after by shearing force, is unfavorable for shearing machine normal operation, therefore the type is same
The cold shears for being unsuitable for super-tonnage uses；
For rack cold shears (closed type) welded steel structured for 850 tons~1300 tons of planer-type groups, due to the rack
Blank is docked using steel plate downhand welding and is manufactured, therefore be there is welding front spring groove section and required high, particularly lower slide main reinforcement
With the vertical downhand weld of machine frame at two sides, large-tonnage is often needed to impact working condition when shearing special steel, has exceeded welded section at this
The load force value that intensity can bear first generates fine cracks from weak links such as its defect, stress raisers, afterwards constantly slowly
Become larger elongated, final main stress steel plate leg is often in cracking shape connection separation failure, and equipment damage is caused to shut down；In addition,
The frame top is in hatch frame without pin, it is coupled closing using bolt with front panel, be unable to control constrain knife rest, guide rail by
Deflection after power causes active service upper tool post cutting edge movement clearance and changes generation drift, directly affects finished product shearing quality.Separately
Its outer transmission system drives main crankshaft with two-stage enclosed helical gear, shear caused by axial thrust load must be by end plate
Conjunction bolt is born, under repeated stock, shock effect, end plate conjunction bolt occurs usually connection and loosens, disengages, and causes to cut
Cut portion's integral rigidity, intensity is deteriorated, until shutting down and playing its periphery reinforcement plate angle hoop by being welded integrated processing.
Summary of the invention
It is easily loosened to solve body connection part when special steel rolling line cold shears machine equipment absorbs impact load, strength weld deformation
The problem of leading to cracking, for this purpose, the present invention provides a kind of mortise and tenon racks for cold shears.The present invention is with new design means
