Description
Technical field
The present invention relates to the bindiny mechanism of hydraulic gate type guillotine shear upper tool post and hydraulic cylinder.
Background technology
Hydraulic gate type guillotine shear upper tool post is a basic element of character of plate shearing machine, bikini rolling guide is adopted to support before and after it, bottom and fixing bottom knife keep certain gap blade and shearing inclination, top is connected with two hydraulic cylinders, make upper and lower rectilinear motion by the driving of hydraulic cylinder, realize shearing function.Therefore the connection of hydraulic gate type guillotine shear upper tool post and hydraulic cylinder must meet following requirement: 1, meet gap blade and adjust requirement; 2, angle of shear adjustment requirement is met; 3, the direct delivery request of shearing force is met.The connection of existing hydraulic gate type guillotine shear upper tool post and hydraulic cylinder adopts suspension rod bolt to add butterfly spring to connect or fixed center connects apart from gusset piece mostly.There is following problem in these two kinds of structures: butterfly spring will be leaned on to be out of shape when 1, suspension rod bolt adds butterfly spring connected mode adjustment gap blade and the angle of shear and realize, suspension rod bolt is in stress all the time, and both sides bolt height and pretightning force are not easily grasped; When 2, adjusting the angle of shear, be that suspension rod bolt or gusset piece all can change former vertical hanging state generation inclination, affect the stressed of piston rod; 3, fixed center is apart from gusset piece connected mode when shearing, and shearing force can be delivered on bearing pin by gusset piece thus to be produced destruction and cause the accident.
Summary of the invention
Problem to be solved by this invention is to provide the floating type bindiny mechanism of bias of hydraulic gate type guillotine shear upper tool post and hydraulic cylinder, this mechanism can realize remaining vertical hanging state at adjustment gap blade with connecting rod during the angle of shear, keep upper tool post under vertical hanging state, between hydraulic cylinder piston rod end portion ballhead and spherical base, have a fixing minim gap, when can guarantee to shear, shearing force acts directly on upper tool post, thus completely eliminate the generation causing substantial equipment accident because of the destruction of connector, ensure safety.Meanwhile, this mechanism's mounting and adjusting is convenient.
The floating type bindiny mechanism of bias of hydraulic gate type guillotine shear upper tool post of the present invention and hydraulic cylinder, it comprises two unit in left and right, and each unit includes the positioner of hydraulic cylinder, hydraulic cylinder seat, piston rod, connecting rod, axle end baffle plate, piston rod end ballhead, spherical base, float supporting plate, upper tool post, bearing pin, eccentric shaft, eccentric shaft; The hydraulic cylinder seat on the left side is welded on left column and front panel, and the hydraulic cylinder seat on the right is welded on right column and front panel; Hydraulic cylinder is arranged on hydraulic cylinder seat; Piston rod end ballhead is assemblied in the end of piston rod, matches with the top sphere of spherical base, and the lower plane of spherical base is bearing in the upper plane of upper tool post; Bearing pin is contained in the pin shaft hole of hydraulic cylinder piston rod; Maximum gauge section in the middle of eccentric shaft is contained in the eccentric pivot hole of upper tool post, and two floating supporting plates are enclosed within eccentric shaft, and abut against on the shaft shoulder at eccentric shaft interlude two ends respectively; The upper lower opening of front-rear linkage is enclosed within the rear and front end of bearing pin and eccentric shaft respectively, and by axle end baffle plate axial location; The positioner of eccentric shaft is connected with eccentric shaft.
Design principle and the course of work of the eccentric floating type bindiny mechanism of the present invention are: according to the pin shaft hole eccentricity value in vertical direction on the adjusting range determination upper tool post eccentric pivot hole of the angle of shear and piston rod and the eccentric throw of eccentric shaft, by eccentric shaft positioner, eccentric shaft position block is adjusted to horizontal level, now in the middle of eccentric shaft, maximum gauge section center and the front and back eccentric segment line of centres are in level, eccentric segment center and the bearing pin line of centres be contained in piston rod upper pin hole of eccentric shaft are in plumbness, connecting rod is in the weight that vertical hanging state carries upper tool post, on upper tool post, on plane and upper tool post, the eccentric segment line of centres of left and right two eccentric shafts is in level, the supporting plate that floats is concordant with plane on upper tool post.During shear, upper tool post is descending under piston rod promotes, when upper tool post blade contact is descending by of short duration stopping during shear material, now eccentric shaft will rotate clockwise under the promotion of connecting rod, connecting rod and floating supporting plate will float downwards along with the rotation of eccentric shaft, until piston rod end ballhead contacts completely with spherical base, the active force of such hydraulic cylinder i.e. shearing force will be acted directly on upper tool post by piston rod end ballhead and spherical base thus complete shearing work.Shear complete, piston rod is up, and now eccentric shaft will rotate counterclockwise first return under the drive of connecting rod, drives upper tool post return again under making connecting rod be in vertical hanging state.During the adjustment angle of shear, on upper tool post, on plane and upper tool post, the eccentric segment line of centres of left and right two eccentric shafts will become heeling condition from original level, now as connecting rod will be kept still to be in vertical hanging state, on upper tool post, the eccentric segment line of centres of two eccentric shafts just becomes hypotenuse from former level right angle limit, its distance just needs to increase, by regulating the adjustment bolt of left side eccentric shaft positioner, the eccentric shaft on the left side is rotated counterclockwise, regulate the adjustment bolt of the right eccentric shaft positioner that the eccentric shaft on the right is rotated clockwise simultaneously, the eccentric segment center of left and right two eccentric shaft on such upper tool post will upwards outside be mobile simultaneously, its distance will increase, till connecting rod is in vertical hanging state, float supporting plate also along with the rotation upwards floating picking-up spherical base of eccentric shaft during adjustment, to keep having a fixing minim gap between piston rod end ballhead and spherical base, prevent from producing impact because of excesssive gap.
