Abstract
A strip steel end warping mechanism of a strip steel flattening unit comprises a frame. The frame is installed on a front support of the unit, two hydraulic cylinders are respectively arranged on the left side and the right side of the inside of the frame in a combining mode, a press plate is hinged to piston rod heads of the hydraulic cylinders, and a chopping plate is arranged on a cross beam at the lower portion of the frame in a combining mode. When the strip steel end passes through the end warping mechanism, piston rods of the hydraulic cylinders extend outside to drive the press plate to move downward. The strip steel end warps upward under the joint action of the protrusion of the press plate and a groove of the chopping plate. The strip steel end warping mechanism is simple, compact, economic, practical, capable of effectively increasing steel penetrating speed and production rate of the unit and good in popularization and application prospect.
Description
Technical field
The invention belongs to metallurgical machinery equipment belt steel flating machine set technology field, be specifically related to a kind of band steel nose mechanism of belt steel flating unit.
Background technology
In the belt steel flating unit, the S roller is set to increase forward and backward tension force between dressing stand and uncoiler, the coiling machine, improve band steel percentage elongation and guarantee smooth quality.When smooth, each winding steel capital will be passed through and wear the band operation, and whether it reaches holding time smoothly directly influences unit productivity ratio.In the S roller, experience a series of flexural deformations owing to wear when band band steel, often formed the shape that the deflection guide plate is buckled downwards after taking the lead to pass the S roller.Cause in follow-up crossing process, take the lead and guide plate between scraping each other, anterior band steel forms protuberance through regular meeting, causes and wears the band difficulty.Even can wear band reluctantly, after getting into dressing stand, the taking the lead of following button be easy to scratch bottom working roll, cause the roller consumption.Like untimely discovery, roll can duplicate belt steel surface with scar when smooth production, cause product defective.To the problems referred to above, existing processing method has following two kinds usually: a kind of is behind the S roller, shearing equipment to be set, and cuts crooked serious taking the lead; Another kind be artificial will take the lead to bend along the strip width direction with clamp it is upwarped slightly, be convenient to wear band.First kind of mode, the cutting edge of shearing equipment involves great expense, and maintenance cost is high, and causes certain band steel loss; The second way, the efficient of artificial treatment is low, and nose is irregular.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of band steel nose mechanism of belt steel flating unit, compact, economical and practical, easy to maintenance, automaticity and efficient are high.
For realizing above-mentioned purpose, the present invention takes following technical scheme:
A kind of band steel nose mechanism of belt steel flating unit; Comprise framework 1, hydraulic cylinder 2, pressing plate 3 and chopping block 4; Framework 1 is installed on the machine fore-stock of unit, and framework 1 is a square shape, and two hydraulic cylinders 2 are respectively being incorporated into the framework 1 inner left and right sides; Pressing plate 3 is hinged with the piston rod head of hydraulic cylinder 2, and chopping block 4 is being incorporated on the crossbeam of framework 1 bottom.
Described pressing plate 3 working faces are lower surface, center protrusion, and the top is semicircle, and band steel entrance side is the plane, and band steel exports side is the inclined-plane.
Described chopping block 4 working faces are upper surface, are lower than rolling time band steel height, are processed with a spoonful connected in star, and kettleholder is in band steel entrance side, and spoon connected in star bottom is corresponding with the half-circle projection of pressing plate 3, and curvature is identical with it.
The present invention is owing to take above technical scheme, and it has the following advantages:
1. the present invention is simple and compact for structure, and is economical and practical.
2. the present invention can accomplish band steel nose fast, and nose is neat, is beneficial to unit and wears band fast.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is carried out detailed description.
See figures.1.and.2, a kind of band steel nose mechanism of belt steel flating unit comprises framework 1, hydraulic cylinder 2, pressing plate 3 and chopping block 4, and framework 1 is installed on the machine fore-stock of unit; Framework 1 is a square shape, and two hydraulic cylinders 2 are incorporated into the framework 1 inner left and right sides with 5 on screw respectively, and with reference to Fig. 3, pressing plate 3 is hinged with the piston rod head of hydraulic cylinder 2 through pin 6; Its working face is a lower surface, center protrusion, and the top is semicircle, band steel entrance side is the plane; Band steel exports side is the inclined-plane, and with reference to Fig. 4, chopping block 4 is incorporated on the crossbeam of framework 1 bottom through 8 on bolt 7 and nut; Its working face is a upper surface, is lower than rolling time band steel height, is processed with a spoonful connected in star; Kettleholder is in band steel entrance side, and spoon connected in star bottom is corresponding with the half-circle projection of pressing plate 3, and curvature is identical with it.
Operation principle of the present invention is:
Normal when rolling, band steel nose mechanism is set behind the S roller, the piston rod of hydraulic cylinder 2 is a retracted mode.When unit was worn band, after the band steel passed the S roller, when taking the lead through this nose mechanism, unit suspends wore band.Then, the piston rod of hydraulic cylinder 2 stretches out, and it is descending to drive pressing plate 3, will take the lead to be clipped between pressing plate 3 lower surfaces and chopping block 4 upper surfaces.Continue to exert pressure, under the common clamping action of groove of the projection of pressing plate 3 and chopping block 4, elastic-plastic deformation takes place in band steel toe portion, and formation upwarps.After this mechanism accomplishes nose work, the withdrawal of the piston rod of hydraulic cylinder 2, the operation of unit relevant device continues to accomplish and wears band.
This mechanism has been successfully applied in many smooth units, has all effectively promoted unit and has worn tape speed, has improved unit productivity ratio, and its popularizing application prospect is good.
