Background technology
The circle shear of hot-rolled sheet strip steel finishing line is used for that steel band is carried out width and shears.Fig. 1 is the schematic diagram of the circle shear of existing hot-rolled sheet strip steel finishing line, and wherein (a) is front view, (b) is vertical view.Its shearing width adjustment realizes that by the adjustment of driving side circle shear frame 1 and active side circle shear frame 2 driving side circle shear frame 1 and active side circle shear frame 2 all are installed in the fixed guide of base 5 by sliding seat 3.Sliding seat 3 drives to regulate by the screw mandrel (not shown) under the sliding seat 3 and moves, and then adjusts driving side circle shear frame 1 and active side circle shear frame 2 on it, realizes the shearing width adjustment.
The screw mandrel of sliding seat 3 has location, locking effect.But after using certain hour, because the free gap between sliding seat 3 and the screw mandrel increases, and the stressed easy overload of screw mandrel, cause fit clearance further to increase, cause circle shear machine frame at two sides 1,2 that relative beat and displacement to a certain degree take place, and then cause seriously reducing between the circle shear machine frame at two sides 1,2 apart from hold facility, and this is for the hot rolled plate of shearing certain width, and the width value of steel plate is inaccurate after directly having caused shearing.When steel band when initially penetrating circle shear because bear the effect of steel plate impact shear power, side-play amount and beat amount to a certain degree takes place in the circle shear frame 1,2 of both sides at once in the opposite direction, causes shearing width to increase at once.According to field measurement, the width levels increase of shearing the back steel plate can reach more than the 4mm.Be directed to this, the production scene adopts frequent artificial adjustment mode to carry out desultory production, has seriously restricted equipment capacity.
Summary of the invention
For addressing the above problem, the utility model provides a kind of circle shear rack locking device, and the sliding seat of circle shear machine frame at two sides is locked on the fixed guide, guarantees relative slip and beat that the circle shear machine frame at two sides does not take place under the effect of shearing impact power.
For achieving the above object, circle shear rack locking device of the present utility model, comprise: a pair of jig arm, hydraulic cylinder floats, supporting traverse and a pair of clamp guide rail, the afterbody of described jig arm links to each other with piston rod with the cylinder bottom of described unsteady hydraulic cylinder respectively, and the middle part of described jig arm is fixed on the described supporting traverse by bearing pin respectively, and described clamp guide rail is separately fixed at the two ends of described supporting traverse by bolt.
The head of described jig arm is fixed with copper packing respectively.
Adopt rolling bearing to be connected between the afterbody of the cylinder bottom of described unsteady hydraulic cylinder and piston rod and described jig arm with rotating shaft.
The circle shear frame of effectively controlling circle shear rack locking device of the present utility model does not take place to slide and beat when shearing steel plate, the setting width value that can well keep circle shear, guarantee that the width accuracy level of shearing the back steel plate satisfies production requirement, has improved production capacity simultaneously.

The specific embodiment
Fig. 2 is the schematic diagram that circle shear rack locking device of the present utility model is installed in the circle shear of hot-rolled sheet strip steel finishing line, and wherein (a) is front view, (b) is vertical view.Circle shear rack locking device 10 of the present utility model places on the fixed guide 4 of circle shear, and locking device 10 is rigidly connected with the sliding seat of circle shear frame 1,2, and its mode can adopt welding or bolt connection etc.During beginning to clip to the whole shearing of shearing end, circle shear can all the time both sides circle shear frame 1,2 and fixed guide 4 be locked, to guarantee that both sides circle shear frame 1,2 can remain at former desired location, do not take place to slide relatively and beat, the steel plate width value after guaranteeing to shear is in reasonable level all the time.
Fig. 3 is in the schematic diagram of locking state for circle shear rack locking device of the present utility model, i.e. the left view of circle shear rack locking device among Fig. 2 (a), and Fig. 4 is in the schematic diagram of open mode for circle shear rack locking device of the present utility model.As shown in the figure, circle shear rack locking device of the present utility model comprises: a pair of jig arm 101a, 101b, hydraulic cylinder 102 floats, supporting traverse 103 and a pair of clamp guide rail 104a, 104b, the afterbody of described a pair of jig arm 101a, 101b links to each other with piston rod with the cylinder bottom of described unsteady hydraulic cylinder 102 respectively, the middle part of described a pair of jig arm 101a, 101b is fixed on the described supporting traverse 103 by bearing pin respectively, and described a pair of clamp guide rail 104a, 104b are separately fixed at the two ends of supporting traverse 103 by bolt.
A pair of clamp guide rail 104a, 104b is used for and being slidingly connected of fixed guide 4, the locking device that makes circle shear frame of the present utility model under open mode can with fixed guide 4 relative slips.
The head of described a pair of jig arm 101a, 101b is fixed with copper packing 105a, 105b respectively, is used to increase the wearability of jig arm 101a, 101b.Copper packing 105a, 105b can fix by screw.Also can have horizontal stria, its objective is the frictional force that increases with guide pass, the effect that reach clamping, keeps on surface with fixed guide 4 contacts side surfaces.
Preferably adopt rolling bearing to cooperate rotating shaft to be connected between the afterbody of the cylinder bottom of described unsteady hydraulic cylinder 102 and piston rod and described a pair of jig arm 101a, 101b, the piston rod of hydraulic cylinder 102 of avoiding floating is being stretched, is being born extra flexural force in the compression process, thereby improves the service life of the hydraulic cylinder 102 that floats.
Before circle shear begins to shear, at first the circle shear control system is sent fuel supply signal to the hydraulic oil supply system of the hydraulic cylinder 102 that floats, and to the rod chamber fuel feeding, the piston rod that drives the hydraulic cylinder 102 that floats begins to shrink, and then drive jig arm 101a, 101b Unscrew, as shown in Figure 4.At this moment, the operative employee can progressively to adjust machine frame at two sides according to the steel plate thickness in the manufacturing plan sheet, steel grade material be the relative position that active side circle shear frame 1 and driver plate are cut side frame 2.
In case the shearing width that active side circle shear frame 1 and driver plate are cut between the side frame 2 is set end, the circle shear control system is sent fuel supply signal to the hydraulic oil supply system of the hydraulic cylinder 102 that floats, to the rodless cavity fuel feeding, and shed the hydraulic oil of rod chamber, piston rod begins to stretch both sides jig arm 101a, 101b oppositely moves, jig arm 101a, 101b is around connecting jig arm 101a, the bearing pin of 101b and supporting traverse 103 rotates, while jig arm 101a, the copper packing 105a that the 101b head is installed, 105b contacts with fixed guide 5, and begin to exert pressure, limited clamp guide rail 104a well, relative shift between 104b and the fixed guide 4.Circle shear rack locking device 10 of the present utility model is rigidly connected by clamp guide rail 104a, 104b and sliding seat 3, the relative shift that both sides circle shear frame 1,2 produces when bearing shearing impact power and lateral thrust so the clamping of jig arm 101a, 101b action can well be drawn up, thus the precision level of shearing width guaranteed.
