Abstract
The invention provides a novel scraper knife, which can be used for uncoiling a strip steel coil in a strip steel assembly line during industrial production. The purposes of improving time from uncoiling to feeding a pinch roll, improving unit efficiency, preventing the scraper knife from scuffing a steel strip, improving unit yield and improving economic benefits can be achieved. The novel scraper knife comprises a scraper knife, a scraper knife lifting mechanism and a swinging mechanism, wherein the scraper knife is connected with the swinging mechanism through the scraper knife lifting mechanism; a roller lifting mechanism is mounted at the adjacent side of the scraper knife lifting mechanism; a roller is connected at the top of the roller lifting mechanism; the other end of the scraper knife lifting mechanism is connected with the swinging mechanism; the scraper knife lifting mechanism and the roller lifting mechanism are hydraulic oil cylinders; the scraper knife is made of alloy steel; and a roller is made of the alloy steel. The novel scraper knife provided by the invention is mainly applied to feeding areas of a steel strip slitting machine and a welding pipe unit.
Description
Technical field
The novel perching knife of the present invention is when commercial production, the novel perching knife that uses when the band coil of strip in the output strip line is carried out uncoiling.
Background technology
The perching knife of unit use in the past has only perching knife to go up and down and swing, after coil of strip first lap shovel left by perching knife; Can only rely on perching knife with steel band jack-up; And the steel band of this moment also need continue to be fed forward, and will steel band jack-up certain height just can be sent into pinch roll, behind the entering pinch roll; Perching knife just can fall, and effect could be accomplished.But exist perching knife jack-up steel band, the elastic force of steel band is to pressing down perching knife, and the structures shape of perching knife; Very big friction force is arranged between the two, and this has just caused the decoiling unit and the feeding that are fed forward to bludgeon cunning, send the phenomenon of motionless steel band; Can only take the limit to send steel band, perching knife is swung on the limit backward, send a segment distance after perching knife fall; Jack-up steel band again after the swing forward, steel band is sent in swing again.This just causes and send the chronic of steel band, has a strong impact on the production efficiency of unit, has reduced the production capacity of unit.And send in the process of steel band in swing, the situation that perching knife scratches steel band also inevitably takes place, cause the steel band part to scrap, caused the finished product rate to descend, influence the economic benefit of unit.
Summary of the invention
The objective of the invention is to improve the time of steel band, improve unit efficiency, and avoid perching knife to scratch steel band, improve the yield rate of unit, increase economic efficiency from uncoiling to the entering pinch roll.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: novel perching knife comprises perching knife, perching knife lifting mechanism, swinging gear; Perching knife is connected with swinging gear through the perching knife lifting mechanism; The adjacent side of perching knife lifting mechanism is equipped with the carrying roller lifting mechanism, and the top of carrying roller lifting mechanism is connected with carrying roller, and the other end of perching knife lifting mechanism links to each other with swinging gear.
Described perching knife lifting mechanism is a hydraulic ram.
Described carrying roller lifting mechanism is a hydraulic ram.
Described carrying roller is a column structure.
The material of described carrying roller is an alloy steel.
The material of described perching knife is an alloy steel.
The beneficial effect that the present invention is compared with prior art had is:
1, the place ahead of perching knife and perching knife lifting mechanism is equipped with carrying roller and carrying roller lifting mechanism, and carrying roller is connected with swinging gear through the carrying roller lifting mechanism, after steel band head shovel left by perching knife; Carrying roller lifts, and perching knife withdrawal then holds up steel band with carrying roller; At this moment, steel band and carrying roller are friction of rolling, just can steel band be delivered to pinch roll with very little strength; Steel band can get into pinch roll soon from making, and has improved unit efficiency, simultaneously because steel band and carrying roller are friction of rollings; There is not the possibility that scratches steel band, thereby improved yield rate, improved the economic benefit of unit simultaneously.
2, perching knife and carrying roller are alloy steel; Perching knife is an alloy steel, makes easily perform fighting band and insert the coil of strip first lap of shovel of perching knife, and breaks the first lap steel band into two with one's hands, and carrying roller is an alloy steel, because carrying roller is when carrying steel band, steel band and carrying roller are friction of rolling, and the resistance to abrasion that then strengthens carrying roller is necessary.
Description of drawings
Fig. 1 is a structural representation of the present invention,
1 is that perching knife, 2 is that perching knife lifting mechanism, 3 is that swinging gear, 4 is that carrying roller, 5 is the carrying roller lifting mechanism among the figure,
The specific embodiment
As shown in Figure 1; Novel perching knife comprises perching knife 1, perching knife lifting mechanism 2, swinging gear 3; Perching knife 1 is connected with swinging gear 3 through perching knife lifting mechanism 2; The adjacent side of perching knife lifting mechanism 2 is equipped with carrying roller lifting mechanism 5, and the top of carrying roller lifting mechanism 5 is connected with carrying roller 4, and the other end of perching knife lifting mechanism 2 links to each other with swinging gear 3.Perching knife lifting mechanism 2 is a hydraulic ram with carrying roller lifting mechanism 5.The material of perching knife 1 is an alloy steel, and the material of carrying roller 4 is an alloy steel.
After coil of strip put into decoiling unit; Start perching knife lifting mechanism 2 perching knife 1 is risen to the desired position; Driving perching knife 1 around fixedly axis of revolution swing, open coil of strip and break the first lap steel band into two with one's hands thereby shovel, and start perching knife lifting mechanism 2 rise perching knives 1 jack-up first lap steel band by swinging gear 3; Start carrying roller lifting mechanism 5 simultaneously carrying roller 4 rises are held by the steel band of perching knife 1 jack-up, start perching knife lifting mechanism 2 then perching knife 1 is fallen; When carrying roller 4 is held coil of strip, start decoiling unit and feeding roller, steel band is fed forward; Steel band delivers into pinch roll by carrying roller 4 on carrying roller 4; After steel band gets into pinch roll, start carrying roller lifting mechanism 5 with carrying roller 4 landing, pinch roll is sent to subsequent processing with steel band.
