Description
Technical field
The utility model belongs on the STEELMAKING PRODUCTION line for the vitals on the special equipment flash trimmer equipment of rooting out slag on steel billet burnisher dege mouth, particularly the knife bar assembly of a kind of capable of regulating flash trimmer blade and billet surface adhesion.
Background technology
the disk scraper type burr grinding machine knife bar assembly of each steel mill's application has open defect at present, it is that source of the gas drives that its knife bar drives, (steel billet temperature is up to 700 ℃ because the flash trimmer environment for use is relatively poor, and adopt the cooling blade well of air and knife bar to lower the temperature, there is dust in environment simultaneously), thereby cause the poorly sealed knife bar that causes of knife bar lifting cylinder sleeve can not rise to the operating position because of cylinder leakage tester, although or knife bar rises to the operating position, but because the adhesive force between cylinder leakage tester blade and billet surface reduces, when causing blade to run into the bristle thorn, knife bar is retracted and is not reached the deburring effect.
Summary of the invention
Technical problem to be solved in the utility model is: the knife bar assembly of a kind of adjustable blade for flash trimmer and billet surface adhesion is provided, has improved unhairing efficient.
The technical solution of the utility model is:
A kind of cutting disc type flash trimmer knife bar assembly is characterized in that: be comprised of knife bar, upper guide bush, dust-proof seal ring, spring, adjusting sleeve, locking nut, lower guide pin bushing, dish spring, channel nut, the special envelope of department and split pin; Described knife bar forms by alloy steel forging and through the heat treatment manufacturing, in order to increase its surface abrasion resistance intensity, the whole hard chrome plating of knife bar; Described upper guide bush is provided with dust-proof seal ring, and is placed in knife bar top; Described adjusting sleeve is provided with lower guide pin bushing outward, and described lower guide pin bushing top is provided with locking nut; Described adjusting sleeve outer surface has form of thread, and locking nut and lower guide pin bushing all are bound up by screw thread and adjusting sleeve; Described adjusting sleeve is placed in the knife bar bottom, is provided with spring on the knife bar between adjusting sleeve and upper guide bush.
The above dish spring is enclosed within on knife bar, and channel nut connects with knife bar by screw thread, and split pin is by the fixing channel nut in the hole on knife bar.
There is annular groove on the inner surface of the above adjusting sleeve, and the special envelope of department is arranged in groove.
The utility model characteristics and effect are: this knife bar assembly has carried out the new design that updates, revised the deficiency of the pneumatic knife bar assembly of existing circle, and increased new function, make the burr removal efficient of flash trimmer be greatly improved, the flash trimmer burr clearance of using new knife bar assembly promotes greatly.Concrete characteristics are as follows:
1, added flexible member in the design of knife bar assembly---spring, the material of spring is through preferred, can anti-300 ℃ of high temperature and indeformable, and at high temperature do not affect its mechanical performance, the elasticity of spring makes knife bar be in for a long time the rise state, thereby guarantee that all blades of flash trimmer all have good contact with billet surface, make blade can automatically adapt to the uneven distortion of billet surface, guarantee deburring efficient;
2, in the design of knife bar assembly, the use that has added adjusting sleeve, pass through threaded adjustment between adjusting sleeve and lower guide pin bushing, thereby the elongation of control spring from shorten the requirement adapt to different slab thickness blade adhesive force, to the constant steel billet of thickness, through the extension and contraction control of adjusting sleeve and lower guide pin bushing, extended the service life that drives high temperature resistant spring in the knife bar assembly, reduced simultaneously the maintenance cost of flash trimmer.
Description of drawings
Fig. 1 is the cutaway view of knife bar assembly
In figure: guide pin bushing, 6-adjusting sleeve, 7-screw, 8-packing ring, 9-dish spring, 10-channel nut, 11-dust-proof seal ring, 12-locking nut, 13-split pin under 1-knife bar, 2-upper guide bush, 3-spring, the special envelope of 4-department, 5-.
The specific embodiment
As shown in the figure, the utility model is comprised of knife bar 1, upper guide bush 2, dust seal 11, spring 3, adjusting sleeve 6, locking nut 12, lower guide pin bushing 5, dish spring 9, channel nut 10, the special envelope 4 of department and split pin 13, wherein:
Knife bar: knife bar 1 is formed through forging by superior alloy steel, and promotes its mechanical performance by heat treatment, for improving its surface abrasion resistance, again its outer surface has been carried out the coating processing; Knife bar 1 is used for bearing the impulsive force that the steel billet operation produces, and is the chief component of knife bar assembly.
Upper guide bush: dust-proof seal ring 11 is housed in upper guide bush 2, and upper guide bush 2 is mainly used to righting knife bar 1, and dust-proof seal ring 11 is to avoid knife bar 1 directly to contact with upper guide bush 2, thereby extends the service life of knife bar 1.
Adjusting sleeve: adjusting sleeve 6 is contained in lower guide pin bushing 5, and locked on lower guide pin bushing 5 with locking nut 12, and spring 3 is contained between adjusting sleeve 6 and knife bar 1, and adjusting sleeve 6 endoporus are equipped with the special envelope 4 of department; Upper guide bush 2 and lower guide pin bushing 5 are separately fixed on cutter platform (not shown), but by regulating the length of adjusting sleeve 6 and locking nut 12 control springs 3, thereby control the blade be bound up on knife bar 1 and the adhesive force between steel billet, to adapt to the not billet bloom size of thickness; The special envelope 4 of department that is arranged in adjusting sleeve 6 separates knife bar 1 and adjusting sleeve 6, thereby has reduced knife bar 1 surface abrasion, extends the service life of knife bar 1 and adjusting sleeve 6, and this is the core component in the knife bar assembly.
The dish spring: the effect of dish spring 9 is impacts of buffering channel nut 10 pairs of adjusting sleeves 6 when deburring finishes, and channel nut 10 and split pin 13 are used in conjunction with and prevent that knife bar 1 from deviating from from upper and lower guide pin bushing, and they are requisite annexes in the knife bar assembly.
The use procedure of knife bar assembly:
Need the use length according to slab thickness and length selection spring 3 when 1, the knife bar assembly is assembled, after length is determined, according to determining with length adjustment adjusting sleeve 6 and lower guide pin bushing 5 and using the locked adjusting sleeve 6 of locking nut 12.
2, when slab process flash trimmer, the CPU that controls the knife bar assembly controls deburring machine knife platform and rises under the signal of laser detector guides, the blade that is in knife bar assembly upper end is adjacent to billet surface, at this moment spring 3 compresses under external force blade is adjacent to, and automatically adapts to the uneven concavo-convex part of billet surface.
3, steel billet moves on, and flash trimmer is completed the deburring action, and knife bar 1 sets back under spring 3 effects and upsprings, and waits for burr removing step next time.
4, longer service time when the knife bar assembly, when the spring rigidity is not enough, repeat above listed procedure regulation spring 3 initial pressures.
