Further, above-mentioned copper cutter head has two-sided blade.
Because the utility model thin band continuous casting crystallization roller side doctor blade device has adopted technique scheme; Be that the locating piece center has through hole and is located in the sleeve tail end; Ramp blocks has through hole and is placed in the tail end of sleeve, and axle center connecting rod tail end is provided with screw thread and penetrates the locating piece central through hole and is positioned at sleeve, the coaxial sleeve tail end that is positioned at of holder; Hold-down nut is twisted connecting rod tail end screw thread and fastening holder in the axle center; Cutter head cylinder center has through hole and an end and connects copper cutter head, the cutter head cylinder other end be positioned at barrel forward end also axle center connecting rod front end stretch into the through hole of cutter head cylinder, the barrel forward end barrel is provided with screw; Hook bolt is twisted in the screw of barrel forward end barrel and is pushed against the cutter head cylinder, spring be positioned at sleeve also two ends against locating piece and cutter head cylinder.This device can effectively be cleared up the cold steel of crystallization roller end face limit silk in the thin strip casting process; Orderly this device of entering of thread coagulum that the Cast Strip is produced at crystallization roller end face; Alleviate the wearing and tearing that generation and disordered motion because of cold steel limit silk cause crystallization roller end face; Prolong the service life of crystallization roller, guarantee the quality of strip test.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:
Fig. 1 is the structural representation of the utility model thin band continuous casting crystallization roller side doctor blade device,
Fig. 2 is the vertical view of Fig. 1,
Fig. 3 uses sketch map for this device.
The specific embodiment
As depicted in figs. 1 and 2; The utility model thin band continuous casting crystallization roller side doctor blade device comprises sleeve 1, axle center connecting rod 4, locating piece 2, holder 5, hold-down nut 6, spring 9, ramp blocks 3, hook bolt 10, cutter head cylinder 7 and copper cutter head 8; Said locating piece 2 centers have through hole and are located in said sleeve 1 tail end; Said ramp blocks 3 has through hole and is placed in the tail end of said sleeve 1; Said axle center connecting rod 4 tail ends are provided with screw thread and penetrate said locating piece 2 central through holes and are positioned at said sleeve 1; Said holder 5 is coaxial to be positioned at said sleeve 1 tail end, and said hold-down nut 6 is twisted connecting rod 4 tail end screw threads and fastening said holder 5 in said axle center, and said cutter head cylinder 7 centers have through hole and an end connects said copper cutter head 8; Said cutter head cylinder 7 other ends are positioned at the through hole that said sleeve 1 front end and said axle center connecting rod 4 front ends stretch into said cutter head cylinder 7; Said sleeve 1 front end barrel is provided with screw, and said hook bolt 10 twisted in the screw of said sleeve 1 front end barrel and pushed against said cutter head cylinder 7, and said spring 9 is positioned at said sleeve 1 and two ends against said locating piece 2 and cutter head cylinder 7.
Further, for improving the effect of the cold steel of copper cutter head cleaning crystallization roller end face limit silk, above-mentioned copper cutter head 8 has two-sided blade.
As shown in Figure 3, this device is located at crystallization roller 11 end faces during thin strap continuous casting, and copper cutter head 8 is positioned at the circumference place of crystallization roller 11 and has certain clearance with end face; After strip test casting beginning, crystallization roller 11 end faces have thread coagulum, the generation of promptly cold steel limit silk; Its thickness of the continuous accumulation of cold steel limit silk in casting cycle can constantly increase; Be accompanied by the rotating speed of crystallization roller 11, the rotation that crystallization roller 11 does not stop, its circumference of circular cross-section of crystallization roller 11 end faces is around copper cutter head 8 motions of this device; In a single day reach the gap of demarcating between copper cutter head 8 and crystallization roller 11 end faces when cold steel limit silk thickness; Copper cutter head 8 is about to cold steel limit silk and strikes off. and according to the thickness of cold steel limit silk, the spring in this device sleeve can be regulated the pressure of copper cutter head 8 within the specific limits voluntarily, stretches into the distance of barrel forward end simultaneously through a hook bolt scalable cutter head cylinder; Thereby further change the active force of spring, satisfy the requirement of striking off cold steel limit silk with the pressure that guarantees copper cutter head 8; The ramp blocks 3 of this device makes copper cutter head center line become certain included angle with crystallization roller end face, is convenient to remove reliably the cold steel limit silk of crystallization roller 11 end faces.When smooth crystallization roller 11 end faces of casting cycle did not have the silk generation of cold steel limit, copper cutter head 8 can keep certain clearance with crystallization roller 11 end faces always, can not cause any wearing and tearing to crystallization roller 11.
This device need not operating personnel when using and controls, and need not to provide power, relies on spring and ramp blocks in the device to regulate automatically fully, realizes the removing of the cold steel of crystallization roller end face limit silk, the service life of having improved crystallization roller and brush roll.Copper cutter head is designed to patty; So just prolonged the contact camber line of blade greatly with crystallization roller end face; Copper cutter head is the embedded cutter head cylinder that is installed on, and after copper cutter head weares and teares, can make cutter head be operated in the position that wearing and tearing do not take place through rotating copper cutter head certain angle.Ramp blocks can be made into and makes the cutter head center line become 10 ° angle with crystallization roller end face, helps removing cold steel limit silk more and goes out bits, the relief angle of the cutter head of avoiding simultaneously wearing and tearing.Whole apparatus structure is simple, easy accessibility, and easy access is safeguarded.Also can adjust the angle of copper cutter head and crystallization roller end face in advance, the convenient use according to the field operation actual needs.
