Abstract
The utility model relates to the field of cold-rolling strip steel tandem rolling production lines, in particular to a novel width notcher, wherein blades are exchanged outside the cold-rolling strip steel tandem rolling production lines. The width notcher comprises cutter head devices, a shearing platform, a transverse moving frame, a fixed guide rail device and a transverse moving hydraulic cylinder, wherein the cutter head devices are respectively installed on two sides of the transverse moving frame. The width notcher is characterized in that the length of the transverse moving frame and the route of the transverse moving hydraulic cylinder are respectively extended towards two sides of the width direction of a steel board, a certain safety distance is formed between each cutter head device and each side edge of the steel board, and the certain safety distance L is 500 to 800 millimeters. Compared with the prior art, the width notcher has the advantages of being simple in structure, and reasonable in design. By means of increasing of the length of the transverse moving frame and the route of the transverse moving hydraulic cylinder, the cutter devices can be driven out of the cold-rolling strip steel tandem rolling production lines, then an upper blades and lower blades can be exchanged, operation is safe and convenient, normal production can be effectively kept, and production efficiency of the cold-rolling strip steel tandem rolling production lines is improved.
Description
Technical field
The utility model relates to cold-strip steel continuous rolling production line field, relate in particular to a kind of outside the cold-strip steel continuous rolling production line more the Crescent of allowing blade replacement cut.
Background technology
Pickling continuous-rolling, galvanized wire unit and company at the cold-strip steel continuous rolling production line move back on the tandem rolling unit, and width notcher is the necessary equipment supporting with welding machine.After the welding machine band steel welding that two width is different, the two ends of weld seam will stay burr or scar, respectively cut a crescent moon at the two ends of its weld seam with steel during by width notcher, and purpose is to make the strip edge edge of commissure become smooth.
Because frequent shear band steel, the blade of width notcher has wearing and tearing, just needs to change shear-blade.The method of changing at present the width notcher blade has two kinds, and the one, online replacing, both inconvenience was also dangerous; The 2nd, wait to keep in repair or change again when stopping production.Production efficiency is reduced.
Summary of the invention
The purpose of this utility model provides a kind of Crescent and cuts, and overcomes the deficiencies in the prior art, can leave the tandem strip mill production line to knife head device and replace with lower blade outward, improves processing safety, does not affect normal production.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of Crescent is cut, comprise knife head device, cut platform, traversing framework, fixed guide device and traversing hydraulic cylinder, knife head device is separately positioned on the both sides of traversing framework, the length of described traversing framework and the stroke of traversing hydraulic cylinder extend to steel plate width direction both sides respectively, leave one section safe distance between knife head device and the side edge of steel plate.
Described safe distance L is 500-800mm.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, reasonable in design, by increasing traversing lengths of frame and traversing hydraulic cylinder travel, so that can leaving production line, knife head device replaces with blade and bottom knife outward, easy-to-operate can be kept normal production effectively, improves the production efficiency of tandem strip mill production line.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1～Fig. 4, that a kind of Crescent of the utility model is cut the example structure schematic diagram, this equipment is perpendicular to the setting of band steel, comprise knife head device 12, cut platform 5, chaser 6, traversing framework 7, fixed guide 8 and traversing hydraulic cylinder 9 form, two groups of knife head devices 12 are separately positioned on the both sides of traversing framework 7, replace with safely blade 1, bottom knife 2 outward in order to make knife head device 12 can leave production line, the stroke of the length of traversing framework 7 and traversing hydraulic cylinder 9 extends respectively one section safe distance to the steel plate both sides.The scope that traversing framework 7 length increase is safe, and safe distance L is 500-800mm.
Knife head device comprises cutter 1, bottom knife 2, lifting hydraulic cylinder 3 and guide upright post 4, blade 1 is connected on the lifting hydraulic cylinder 3, bottom knife 2 is fixed on the bottom of guide upright post 4 supports, finish shear band steel 11 by guide upright post 4 and lifting hydraulic cylinder 3, two groups of knife head devices are installed in respectively the both sides of traversing framework 7, and can move laterally along fixed guide 8, transverse shifting is finished by the traversing hydraulic cylinder 9 of the left and right sides.
During width notcher work, according to the difference with steel 11 width in service, traversing hydraulic cylinder 9 actions, pulling knife head device 12 move left and right on fixed guide 8, after control is sent signal with the detecting element of steel shear distance position, traversing hydraulic cylinder 9 stops action, shows that the distance of knife head device shear band steel is adjusted to the right place.When the band steel out runs to width notcher from welding machine, control is sent signal with the detecting element of steel position of rest, the band steel is out of service, the lifting hydraulic cylinder 3 that is connected on the cutter 1 moves downwards, pressure steel plate device 10 will be with steel to be pressed in and cut on the platform 5, then cutter 1 and bottom knife 2 beginning shear band steel are sheared and are finished.The detecting element of control hydraulic cylinder travel sends signal, and lifting hydraulic cylinder 3 lifts, and control is sent instruction with the detecting element of steel operation, and the band steel brings into operation.
When replacing with lower blade, traversing hydraulic cylinder 9 actions, pulling knife head device 12 is mobile along to the left and right both sides continuation on the fixed guide 8, until the detecting element of greatest limit position sends signal, traversing hydraulic cylinder 9 stops action, at this moment just can replace with safely lower blade.
