Abstract
The invention discloses rotary trimming shears, which comprise a tool rest, a lower tool shaft, an upper tool shaft in rotary fit with the tool rest, upper and lower cutters which are fixedly arranged at one end of the upper tool shaft and the lower tool shaft respectively to form a shearing structure, and a regulating mechanism for regulating the overlapping amount of the upper and lower cutters, wherein the regulating mechanism comprises an eccentric sleeve which is in rotary fit with the tool rest and a regulating motor which is used for driving the eccentric sleeve to rotate; the lower tool shaft is in rotating fit with and sleeved in the eccentric sleeve; the regulating mechanism uses a motor to directly drive the eccentric sleeve to rotate, so that the overlapping amount of the cutters can be realized; the eccentric sleeve is used in place of the worm and gear mechanism in the prior art, so the equipment is simpler and has lower requirements on installation and maintenance; the manufacturing cost of the equipment is lowered, the influences of the meshing clearance of the worm and gear in the prior art are eliminated, and the regulating precision is increased; the machining requirement is lowered, the machining cost is reduced, and the shears have promotion and application values.
Description
Technical field
The present invention relates to steel rolling produce in the treatment facility of band and sheet material, particularly a kind of strip side cut equipment.
Background technology
In the production process of sheet metal strip and sheet material; The production stage that the side cut right and wrong are usually seen; Each production line all is to adopt the trimming device of disc type to come sheet metal strip and sheet material are cut edge at present; For the trimming device of disc type, the height of trimming quality has very confidential relation with the lap of every side tool dish.Can know through production practices, shear sheet metal strip or sheet material with different-thickness, the size of cutterhead lap is also different, therefore at sheet metal strip or the sheet material of producing different-thickness, need regulate the cutterhead lap.
In the existing technology, the adjusting of cutterhead lap all is to adopt worm and gear to add eccentric form to realize, for example patent 200720083199.4,200720083198.X etc.This governor motion has comprised parts such as turbine, worm screw, eccentric wheel, and system is very complicated, and installation and maintenance are very inconvenient.Simultaneously, this governor motion is also higher to the requirement of machining accuracy and assembly precision, thereby manufacturing cost is higher.Because there is interocclusal clearance in turbine and worm, cause the degree of regulation of this governor motion not high simultaneously.
Therefore, need to explore a kind of disk end trimming shears of brand-new conveniently adjusted cutterhead lap, avoid using the worm and gear governor motion, with the simplification device structure, make things convenient for installation and maintenance, reduce manufacturing cost and improve degree of regulation.
Summary of the invention
In view of this; The present invention provides a kind of disk end trimming shears; This device adopts eccentric bushing to realize the adjusting of cutterhead lap, avoids the use of the turbine and worm governor motion, reaches the simplification device structure, makes things convenient for installation and maintenance, reduces manufacturing cost and improves the purpose of degree of regulation.
Disk end trimming shears of the present invention; Comprise knife rest, down cutter shaft, the last cutter shaft that cooperates with blade holder turns, respectively be fixedly set in the end formation shear constitution of cutter shaft and following cutter shaft upper tool pan, play cutterhead and be used to regulate the governor motion of upper and lower cutterhead lap; Said governor motion comprises eccentric bushing that cooperates with blade holder turns and the adjusting motor that is used to drive the eccentric bushing rotation, and said cutter shaft down is rotatably assorted and is placed in the eccentric bushing.
Further, said cutter shaft end down is provided with the end face power transmission shaft, and the clutch end of said adjusting motor and end face power transmission shaft are along circumferential secure fit;
Further, said adjusting motor is the gear steps motor.
Beneficial effect of the present invention: disk end trimming shears of the present invention have following advantage:
1) adopts eccentric bushing and end face power transmission shaft replacement turbine, worm screw, reduced the complexity of equipment and, simultaneously, also reduced the manufacturing cost of equipment the requirement of installation and maintenance;
2) rotation of employing motor direct-drive eccentric bushing realizes the adjusting of cutterhead lap, has eliminated the influence of interocclusal clearance between the turbine and worm in original technology, has improved degree of regulation, simultaneously, has also reduced processing cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described;
Fig. 1 is a contour structures sketch map of the present invention;
Fig. 2 is a sectional structure sketch map of the present invention;
Fig. 3 is the A place partial enlarged drawing of Fig. 2.
The specific embodiment
Below will combine accompanying drawing that the present invention is elaborated: the disk end trimming shears of present embodiment; Comprise knife rest 1, down cutter shaft 3, the last cutter shaft 2 that is rotatably assorted with knife rest 1, respectively be fixedly set in cutter shaft 2 and following cutter shaft 3 end formation shear constitution upper tool pan 4, time cutterhead 5 and be used to regulate the governor motion of upper and lower cutterhead lap Δ; Said governor motion comprises eccentric bushing 6 that is rotatably assorted with knife rest 1 and the adjusting motor 7 that is used to drive eccentric bushing 6 rotations; Said cutter shaft 3 down fixedly is placed in the eccentric bushing 6, and the fixed center of excentric sleeve is coaxial with the corresponding hole on the knife rest, and excentric sleeve inside is provided with the eccentric pivot hole that is rotatably assorted with following cutter shaft; The pivot that is eccentric shaft is coaxial with following cutter shaft; During the motor rotation, drive eccentric bushing and rotate, the rotation of eccentric bushing causes that cutter shaft moves up and down down.
As the further improvement of technique scheme, said cutter shaft 3 ends down are provided with end face power transmission shaft 3a, and the clutch end of said adjusting motor 7 and end face power transmission shaft 3a are along circumferential secure fit, and the end face power transmission shaft stretches out knife rest, is convenient to assembling.
Further improvement as technique scheme; Said adjusting motor 7 is the gear steps motor; Regulate motor and adopt high-precision motors such as gear steps motor, can regulate automatically through the running realization cutterhead lap of control motor, simultaneously; The body of gear motor is arranged more flexible, is convenient to design end trimming shears compacter.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the aim and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
