Description
Technical field
The utility model relates to a kind of stainless steel and carbon steel plate slab continuous cast mold, particularly a kind of mould at narrow Width adjusting device.
Background technology
The technology that we know conticaster production slab is the process through experience accumulation, theoretical lifting, equipment improvement, and is full-fledged gradually.The visual plant crystallizer of conticaster from the equipment improvement to the technology maturation, also experienced very long period.Only crystallizer Width adjusting device, just experienced from Fixed width, wide to manual accent, transfer wide evolution to hydraulic pressure.At present, mostly each big steel mill is manual Width adjusting device and two kinds of patterns of hydraulic pressure Width adjusting device if adopting.Manually the Width adjusting device equipment mechanism is complicated, inefficiency, maintenance and repair complicacy and cycle are long, can not the realization on-line width adjustment, thereby very big influence production operational availability.Therefore, new conticaster production line of going into operation no longer adopts this structure.Traditional hydraulic pressure Width adjusting device adopts common hydraulic cylinder, and the cylinder plunger head adopts the gudgeon connection to cooperate with narrow limit copper coin support plate.The crystallizer Width adjusting device is monolateral mainly forms the rectangle three-link mechanism by two hydraulic cylinders and support plate, and it is wide to realize shutting down the line downward modulation.Its characteristics: device structure is simple, and is in light weight, and rigidity is strong; Realized that fast velocity modulation is wide; Realized the narrow limit of rapid adjustment copper coin tapering.But because the stability of hydraulic system relation, the tapering of narrow limit copper coin is difficult to maintain for a long time, often produces so-called narrow limit copper coin and " runs awl ", thereby cause the bleed-out accident, and not only influence is produced, and the life-threatening property safety.
Summary of the invention
Be to solve the problems referred to above that prior art exists, the utility model will design the mould at narrow Width adjusting device that the tapering of a kind of narrow limit copper coin can maintain for a long time.
To achieve these goals; The technical scheme of the utility model is following: a kind of mould at narrow Width adjusting device is made up of the identical and symmetrical guiding mechanism of left and right two nested structures; The left side guiding mechanism comprises two rod hydraulic cylinders, bearing block, connecting plate, trunnion base, connecting axle, locking nut, support plate, guide pad and U type clamp; Described pair of rod cylinder plunger head installed connecting axle; And fix with locking nut, trunnion base is installed on the connecting axle, and trunnion base is connected with support plate through trip bolt; The gudgeon of two rod hydraulic cylinders cooperates with bearing block, and bearing block is fixed on the connecting plate, and connecting plate is fixed on the bearing support of a crystalliser left side through fastening bolt, and two two rod hydraulic cylinders, support plate and framework left side bearing supports are formed the rectangle three-link mechanism up and down; On support plate, be fixed with U type clamp, U type clamp clamps narrow limit copper coin and support plate; Two band circular arc lugs of guide pad can slide in the guide groove of trailing edge guide plate and leading edge guide plate and can swing certain angle;
The right side guiding mechanism is identical and symmetrical with left side guiding mechanism structure, and the connecting plate on right side is fixed on the right bearing support of crystalliser through fastening bolt, and two right bearing supports of two rod hydraulic cylinders, support plate and framework are formed the rectangle three-link mechanism up and down;
The afterbody of the plunger in the described pair of rod hydraulic cylinder has the interior ring and the outer shroud of band tapering, and interior ring and outer shroud all have independently hydraulic fluid port.
Compared with prior art, the utlity model has following beneficial effect:
1, the plunger tail in two rod hydraulic cylinders of the utility model has the interior ring and the outer shroud of band tapering, through the independently logical oil of hydraulic fluid port, draining separately, drives outer shroud and holds, unclamps interior ring tightly, thereby realize holding tightly and unclamp plunger.Transfer wide advantage because the utility model not only has conventional hydraulic, and two rod hydraulic cylinder has aforementioned locking function,, be difficult for " running awl ", thereby improved production operational availability greatly so can guarantee narrow limit copper coin tapering during production operation.
2, the utility model can be realized the wide and tapering adjustment of the fast velocity modulation of mould at narrow through two rod Driven by Hydraulic Cylinder and rest pad guiding and swing.
3, the utility model device structure is simple, stable performance, thus greatly reduce repair and maintenance number of times and cycle.
