Technical field
The utility model relates to metallurgical production steel rolling equipment cut edge circle shear technical field, particularly relates to a kind of circle shear gap eliminator.
Background technology
Rotary side trimming shear is widely used in the production of metal plates and strips, and it is for the edge fault of shear product, to improve width accuracy and the quality of finished product.The horizontal clearance of blade up and down of rotary side trimming shear and lap directly determine shear burr and cutting edge life-span, the most important index that therefore, the revolution of blade is beated, gap adjustment and axial float are circle shear performances.
In prior art, circle shear upper slitter shaft-assembling structure comprises: frame arranges through hole, and assemble eccentric bushing in hole, there is the shaft shoulder side of eccentric bushing, and opposite side has end cap, and end cap is fixed on eccentric bushing.Eccentric bushing needs to rotate to regulate cutting edge lap in the hole of frame, therefore, the left side shaft shoulder of eccentric bushing, always has gap between right side end cap and frame, can cause the sudden change of knife-edge gap, thus cause shear fails in actual production.
Utility model content
Main purpose of the present utility model is to provide a kind of circle shear gap eliminator, is intended to the shear fails avoiding causing because of the gap between circle shear eccentric bushing and frame.
For achieving the above object, the utility model provides a kind of circle shear gap eliminator, comprise frame, be installed on the eccentric bushing in machine frame hole, be installed on the cutter shaft in eccentric trepanning, be installed on the blade assembly of described cutter shaft one end, and be fixed on the end cap of described eccentric bushing away from described blade assembly one end, wherein, also spring is provided with and the two ends of this spring abut against with described end cap and described frame respectively between described end cap and described frame, described spring is in compressive state release elastic force and is adjacent to described frame with the shaft shoulder of the close blade assembly one end of straining described eccentric bushing.
Preferably, described spring is butterfly spring.
Preferably, the flared end of described butterfly spring is towards described frame side.
Preferably, described end cap and described eccentric bushing are that screw is connected.
Preferably, described circle shear gap eliminator also comprises the bearing between described eccentric bushing and cutter shaft.
The circle shear gap eliminator that the utility model proposes, by arranging spring between end cap and frame, spring release elastic force, thus the left side shaft shoulder of tension eccentric bushing is adjacent to frame, when blade assembly is sheared, to make to be adjacent to state tighter for shearing force, when regulating lap, eccentric bushing only needs to overcome the frictional force that spring force produces, and can eliminate the gap between circle shear eccentric bushing and frame, and then eliminates blade clearance change and shear fails thereupon that this gap causes.

Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
It should be noted that, in description of the present utility model, term " transverse direction ", " longitudinal direction ", " on ", D score, " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, be not indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See figures.1.and.2, Fig. 1 is the structural representation of the utility model circle shear gap eliminator preferred embodiment; The details structure for amplifying schematic diagram that Fig. 2 is the A place shown in Fig. 1.
In this preferred embodiment, circle shear gap eliminator comprises frame 30, the eccentric bushing 20 be installed in frame 30 hole, the cutter shaft 10 be installed in eccentric bushing 20 hole, be installed on cutter shaft 10 one end blade assembly 40 and be fixed on the end cap 50 of eccentric bushing 20 away from blade assembly 40 one end, wherein, between end cap 50 and frame 30, be also provided with spring 60 and the two ends of this spring 60 abut against with end cap 50 and frame 30 respectively, spring 60 is in compressive state release elastic force and is adjacent to frame 30 with the shaft shoulder of close blade assembly 40 one end of straining eccentric bushing 20.Eccentric bushing 20 is relative to eccentric bushing 20 of the prior art, and its length dimension has increase, for mounting spring 60.This circle shear gap eliminator also comprises the bearing 80 between eccentric bushing 20 and cutter shaft 10.Bearing 80 is for coefficient of friction that is fixing and reduction cutter shaft 10, and bearing 80 is provided with multiple.
Particularly, with reference to Fig. 2, in the present embodiment, spring 60 is preferably butterfly spring.End cap 50 with eccentric bushing 20 for screw is connected.
With reference to Fig. 2, the flared end of butterfly spring is towards frame 30 side.Now, the direction of butterfly spring release elastic force divides force direction identical with blade assembly 40 shearing force, during shearing shearing force make eccentric bushing 20 and frame 30 to be adjacent to state tighter.
Frame 30 arranges through hole, for setting-up eccentricity cover 20, eccentric bushing 20 is provided with the shaft shoulder (left side namely shown in Fig. 1) near the side of blade assembly 40, its side away from blade assembly 40 is provided with the right side shown in end cap 50(and Fig. 1), end cap 50 is pressed on eccentric bushing 20 by screw 70.Eccentric bushing 20 rotates to regulate cutting edge lap in the hole of frame 30.
The circle shear gap eliminator that the present embodiment proposes, by arranging spring 60 between end cap 50 and frame 30, spring 60 discharges elastic force, thus the left side shaft shoulder of tension eccentric bushing 20 is adjacent to frame 30, when blade assembly 40 is sheared shearing force make eccentric bushing 20 and frame 30 to be adjacent to state tighter, during adjustment lap, eccentric bushing 20 only needs the frictional force overcoming the generation of spring 60 elastic force, the gap between circle shear eccentric bushing 20 and frame 30 can be eliminated, and then eliminate blade clearance change and shear fails thereupon that this gap causes.In addition, butterfly spring release elastic force divides force direction identical with shearing force, during shearing shearing force make eccentric bushing 20 and frame 30 to be adjacent to state tighter.In addition, prior art is because needing to control the gap between eccentric bushing 20 and frame 30, and the relative dimensions of all correlated parts needs the corresponding fit dimension of strict control, and after improving, the corresponding size of correlated parts is free tolerance, and element precision requires low.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
