Abstract
The utility model relates to a caster sector section clamp device, in particular to a novel secondary cooling sector section clamp device which is designed aiming at a prior continuous casting steel machine. The utility model comprises a worm pair, a guide sleeve, a lower frame, an upper frame, a lead screw guide pillar and a disc spring, and is characterized in that a hollow cylinder and dish springs are fixed on the upper frame, the worm pair and the guide sleeve are fixed on the lower frame, the upper frame and the lower frame are connected into one body by the lead screw guide pillar through the guide sleeve, the worm pair, the hollow cylinder, the dish springs, a spherical seating and a nut. The caster sector section clamp device is capable of discretionarily adjusting the opening degree of a sector section, and is capable of opening the sector section under a full load.
Description
Affiliated field: the utility model relates to a kind of continuous casting machine fan-shaped segment clamping device, particularly a kind of novel two cold fan-shaped section clamping devices at the design of modern continuous cast steel machine.
Background technology: the fan-shaped section of conticaster is the assembly of up-down rollers row, and its effect is a strand of accepting and pull out the band liquid core that is formed by crystallizer.When guiding, bending, aligning, clamping strand advanced, water spray made strand continue to cool off, and strand is solidified gradually fully, realizes casting continuously.This of strand solidifies with deformation process to be finished by all fan-shaped section, and in this course, the reaction force that strand acts on roller and the bearing thereof affacts on the upper and lower framework of fan-shaped section by bearing block.Therefore, four clamping devices need bear very big axial force and radial load, just can make fan-shaped section become as a whole, realize its function corresponding.
Existing continuous casting machine fan-shaped clamping device has two kinds of fluid pressure type and mechanical types.Hydraulic clamp formula fan-shaped section also has two guiding body side frames except that inside and outside arc frame.Body side frame is fixed on the outer arc frame, and interior arc frame then is installed in the gathering sill of two body side frames.Four clamping hydraulic cylinders can make interior arc frame oscilaltion, and adjust the opening degree of the interior outer arc roller of fan-shaped section by the height of artificial adjustment adjustment piece.
The inside and outside arc frame of mechanical clamping type fan-shaped section links together by four leading screw clamping devices, is rotated by worm screw, worm-gear driven screw mandrel lead, thereby drives the upper and lower motion of upper frame, reaches the purpose of adjusting the fan-shaped section opening degree.The major defect of existing hydraulic clamp is the opening degree that can not adjust fan-shaped section arbitrarily, must the manual change adjusts the thickness of piece, could adjust the thickness of slab, when deflector roll wear and tear, needs to regulate upper and lower framework apart from coming the compensated roller opening degree, operates than difficulty.And the disadvantage of mechanical clamping type is to open fan-shaped section by on-load, is unfavorable for the output of accident base under the bleed-out accident conditions, can only rely on driven roller to force throwing, causes equipment to damage easily.
Summary of the invention: the objective of the invention is to design a kind of opening degree that can adjust fan-shaped section arbitrarily, and can under full load, open the continuous casting machine fan-shaped segment clamping device of fan-shaped section.
The purpose of this utility model is to realize like this, design a kind of continuous casting machine fan-shaped segment clamping device, it comprises that worm gear, fairlead, underframe, upper frame, leading screw guide pillar, dish spring group constitute, it is characterized in that: on upper frame, be fixed with hollow oil cylinder and dish spring group, be fixed with worm gear and fairlead on underframe, framework is fused by fairlead, worm gear, hollow oil cylinder, dish spring group, spheric seating and nut by the leading screw guide pillar up and down.
On the worm gear of described leading screw guide pillar trapezoidal internal thread is arranged, there is trapezoidal external screw thread leading screw guide pillar bottom, and the trapezoidal internal thread on the worm gear of leading screw guide pillar is connected with the trapezoidal external screw thread of leading screw guide pillar bottom.
In the described fairlead feather key is arranged.
Characteristics of the present utility model are, 1, because the worm gear that is fixed on the underframe is motionless, when worm screw drives the worm gear rotation, the leading screw guide pillar moves up and down along feather key in fairlead, thereby driving upper frame moves up and down, therefore can realize the opening degree of far distance automatic adjustment fan-shaped section roller by feather key, to adapt to manufacturing technique requirent.2, the oil-filled pressurization of cavity of resorption of hollow oil cylinder when normal throwing, the oil-filled pressurization of hollow oil cylinder epicoele, cavity of resorption oil extraction compact disc spring group, the axial force that act on the worm gear this moment is the weight of upper frame, load reduces greatly, therefore can drive the leading screw guide pillar by worm gear upper frame is lifted, make top roll leave strand.The main effect of dish spring group is when off-load is all reduced pressure in the upper and lower chamber of oil cylinder, and its pretightning force still can make upper and lower framework join together with certain clamping force, to guarantee carrying out smoothly of transportation, lifting.Can under full load, open fan-shaped section,, enhance productivity, reduce labour intensity to make things convenient for the processing of accident base.3, utilize the characteristic of hydraulic system to prevent apparatus overload, reduce device damage, reduce production costs.
Below in conjunction with the embodiment accompanying drawing the utility model is described further:
Description of drawings: Fig. 1 is the example structure schematic diagram.
Among the figure: 1, worm gear; 2, leading screw guide pillar; 3, feather key; 4, fairlead; 5, dish spring group; 6, hollow oil cylinder; 7, go up spheric seating; 8, lower peripheral surface seat; 9, nut.
Embodiment: worm gear 1 and fairlead 4 are installed on the fan-shaped section underframe, and feather key 3 is housed in the fairlead 4.Hollow oil cylinder 6 and dish spring group 5 are fixed on the upper frame.Framework will be fused by fairlead 4, worm gear 1, hollow oil cylinder 6, dish spring group 5, last spheric seating 7, lower peripheral surface seat 8 and nut 9 by leading screw guide pillar 2 up and down.The trapezoidal external screw thread of trapezoidal internal thread on the worm gear of worm gear 1 and leading screw guide pillar 2 bottoms constitutes a screw thread pair, when worm screw drives the worm gear rotation, leading screw guide pillar 2 moves up and down along feather key 3 in fairlead 4, move up and down thereby drive upper frame, accurately adjust the opening degree of fan-shaped section up-down rollers.The oil-filled pressurization of cavity of resorption of hollow oil cylinder 6 during normal throwing, the oil-filled pressurization of hollow oil cylinder 6 epicoeles, cavity of resorption oil extraction compact disc spring group 5, the axial force that act on the worm gear this moment is the weight of upper frame, load reduces greatly, therefore can drive leading screw guide pillar 2 by worm gear 1 upper frame is lifted, make top roll leave strand.The main effect of dish spring group 5 is that its pretightning force still can make upper and lower framework join together with certain clamping force when off-load is all reduced pressure in hollow oil cylinder 6 upper and lower chambeies, to guarantee carrying out smoothly of transportation, lifting.
