Description

A kind of hot rolling is floated and is cut
Technical field
The invention belongs to hot rolling mechanical equipment technical field, relate to a kind of hot rolling float cut.
Background technology
In hot rolling tinuous production, be commonly used to head, afterbody, the bundling of shearing strip or cut off defective part.But in hot rolling, often because hot rolled strip is of poor quality, take the lead easily " raising one's head and looking " phenomenon to occur, be difficult to pass through in hydraulic shear, so adopting makes floating type by upper scissor blade part, to take the lead smoothly by cutting edge, above float that to cut pressure motionless by rear, then realize shearing function by lower scissor blade unit by Driven by Hydraulic Cylinder.
Traditionally, utilize the sideshake of lower scissor blade on increasing shim pack to adjust on cutting edge, automatically can not realize in the course of the work regulating, must shut down and carry out increase and decrease pad, so not only affect operating efficiency but also add degree of danger.
Summary of the invention
The object of this invention is to provide a kind of hot rolling to float and cut, solve in prior art that to there are two shear blade opening degrees little, utilize the sideshake of lower scissor blade on increasing shim pack to adjust on cutting edge, ineffective problem.
The technical solution adopted in the present invention is, a kind of hot rolling is floated and cut, and is provided with cut cells and down cut unit in frame,
Described upper cut cells is upwards connected with frame upper beam by lifting hydraulic cylinder, both sides, upper cut cells upper surface upwards respectively with a swing arm lower end apical grafting, each swing arm upper end is in transmission connection with an oscillating motor piston rod respectively, oscillating motor cylinder body is fixed on the upper beam of frame, unanimously, installation site is symmetrical arranged for two swing arms and oscillating motor structure;
The two ends of described down cut unit are socketed respectively by the slide rail of slide block and frame inner wall vertical direction, the lower surface of down cut unit and the movable end of drag link hinged, the stiff end of drag link is fixedly connected with gantry base, the driving end of drag link is connected with the piston rod end shearing hydraulic cylinder, and the cylinder body shearing hydraulic cylinder is fixed on outside frame.
Hot rolling of the present invention is floated and is cut, and is further characterized in that:
Down cut unit is connected with the wedge support in frame by regulating connecting rod, and wedge support is connected with motor-driven by spiral upgrading machine, forms side clearance adjusting mechanism.
Upper cut cells be provided with reject chute corresponding to down cut unit clipped position leads to outside frame.
The invention has the beneficial effects as follows, and only need a Driven by Hydraulic Cylinder device to realize shearing function by drag link, by driven by motor spiral lift adjustment blade clearance, and utilize capstan winch to realize fast quick change cutting edge, the opening degree that cutting head cutting tail is cut increases, and reduces cost, saves working space, improve the stability of system, economical, safe, reliable.
Accompanying drawing explanation
Fig. 1 is that hot rolling of the present invention is floated the schematic front view of cutting;
Fig. 2 is that hot rolling of the present invention is floated the schematic top plan view of cutting;
Fig. 3 is that hot rolling of the present invention is floated the cross-sectional schematic of cutting.
In figure, 1. shear hydraulic cylinder, 2. drag link, 3. frame, 4. go up cut cells, 5. down cut unit, 6. reject chute, 7. side clearance adjusting mechanism, 8. lifting hydraulic cylinder, 9. swing arm, 10. oscillating motor, 11. slide blocks.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, apparatus of the present invention structure is,
Cut cells 4 and down cut unit 5 is provided with in frame 3, upper cut cells 4 is upwards connected with frame 3 upper beam by lifting hydraulic cylinder 8, both sides, upper cut cells 4 upper surface upwards respectively with a swing arm 9 lower end apical grafting, each swing arm 9 upper end is in transmission connection with oscillating motor 10 piston rod respectively, oscillating motor 10 cylinder body is fixed on frame 3 upper beam, unanimously, installation site is symmetrical arranged for two swing arms 9 and oscillating motor 10 structure; The two ends of down cut unit 5 are socketed respectively by the slide rail of slide block 11 with frame 3 inwall vertical direction, the lower surface of down cut unit 5 and the movable end (lift side) of drag link 2 hinged, the stiff end of drag link 2 is fixedly connected with frame 3 base, the driving end of drag link 2 is connected with the piston rod end shearing hydraulic cylinder 1, and the cylinder body shearing hydraulic cylinder 1 is fixed on outside frame 3;
Down cut unit 5 is connected with the wedge support in frame 3 by regulating connecting rod, wedge support is connected with motor-driven by spiral upgrading machine, form side clearance adjusting mechanism 7, side clearance adjusting mechanism 7 pulls wedge support by driven by motor spiral upgrading machine, controls the fine setting of down cut unit 5;
Upper cut cells 4 is corresponding with down cut unit 5 clipped position to be provided with reject chute 6 and to lead to outside frame 3.
The operation principle of apparatus of the present invention is,
This floats and cuts device compared with existing shear, and structurally, shear hydraulic cylinder 1 and drive drag link 2, drag link 2 is synchronized with the movement, and orders about down cut unit 5 and moves upward and realize shear history.This floats to cut only needs use one to shear hydraulic cylinder 1 to drive drag link 2, control floating of down cut unit 5, realize whole shear history, solve existing floating well and cut the deficiency of device existence, because drag link 2 stroke increases, lower scissor blade opening degree is obviously increased, easy to maintenance, also improve the stability of device, reduce cost.
Depress upper scissor blade by lifting hydraulic cylinder 8 in upper cut cells 4, and promote swing arm 9 by oscillating motor 10 and prop up upper cutter head downwards, to reduce the impact to upper cutter head when shearing.Before shearing, lifting hydraulic cylinder 8 is upheld and is driven cutter to decline in advance, promotes swing arm 9 push down and cut material during shearing by two oscillating motors 10 by pressure release.Cutting edge is manufactured by special steel, and be loaded on cutting edge seat, cutting edge seat is loaded on carrier parts.When operating, cutting edge seat is locked by spring, lifting hydraulic cylinder 8, oscillating motor 10 when changing cutting edge, shears hydraulic cylinder 1 and all unclamps.4 cutting edges all can use.Changing cutter extracts cutting edge seat out by slideway, drives wireline winch to carry out by motor.Side clearance adjusting mechanism 7 pulls wedge support, to adjust the sideshake of lower scissor blade and upper scissor blade by driven by motor spiral upgrading machine.
