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
The hydraulic gate type guillotine shear upper tool post is a basic element of character of plate shearing machine, adopt the supporting of bikini rolling guide before and after it, bottom and fixing bottom knife keep certain gap blade and shearing inclination, top with are connected hydraulic cylinder and connect, make up and down rectilinear motion by the driving of hydraulic cylinder, realize shearing function.Therefore the hydraulic gate type guillotine shear upper tool post must satisfy following requirement with being connected of hydraulic cylinder: 1, satisfy gap blade and adjust requirement; 2, satisfy the angle of shear and adjust requirement; 3, satisfy the direct delivery request of shearing force.Existing hydraulic gate type guillotine shear upper tool post with mostly adopt the suspension rod bolt to add the butterfly spring connection being connected of hydraulic cylinder or fixed center connects apart from gusset piece.There is following problem in these two kinds of structures: 1, the suspension rod bolt adds when the butterfly spring connected mode is adjusted gap blade and the angle of shear and will be out of shape to realize by butterfly spring, and the suspension rod bolt is in stress all the time, and both sides bolt height and pretightning force are difficult for grasping; When 2, adjusting the angle of shear, be that suspension rod bolt or gusset piece all can change the former state generation inclination of vertically hanging, affect the stressed of piston rod; 3, when shearing, generation destruction causes the accident fixed center on the bearing pin thereby shearing force can be delivered to by gusset piece apart from the gusset piece connected mode.
Summary of the invention
Problem to be solved by this invention provides the eccentric floating type bindiny mechanism of hydraulic gate type guillotine shear upper tool post and hydraulic cylinder, this mechanism can realize that connecting rod remains the vertical state of hanging when adjusting gap blade with the angle of shear, keep upper tool post between the hydraulic cylinder piston rod end section ballhead and spherical base a fixing minim gap to be arranged vertically hanging under the state, shearing force acts directly on the upper tool post in the time of can guaranteeing to shear, thereby thoroughly eliminated the generation that causes the substantial equipment accident because of the destruction of connector, ensured safety.Simultaneously, this mechanism installs easy to adjust.
The eccentric floating type bindiny mechanism of hydraulic gate type guillotine shear upper tool post of the present invention and hydraulic cylinder, two unit about it comprises, each unit include 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 the front panel, and the hydraulic cylinder seat on the right is welded on right column and the front panel; Hydraulic cylinder is installed on the hydraulic cylinder seat; The 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 on 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 the eccentric shaft is contained in the eccentric pivot hole of upper tool post, and two unsteady supporting plates are enclosed within on the eccentric shaft, and abut against respectively on the shaft shoulder at eccentric shaft interlude two ends; The up and down hole of front-rear linkage is enclosed within respectively the rear and front end of bearing pin and eccentric shaft, and by the axle end baffle plate axial location; The positioner of eccentric shaft links to each other with eccentric shaft.
Design principle and the course of work of the eccentric floating type bindiny mechanism of the present invention are: determine pin shaft hole eccentricity value in vertical direction and the eccentric throw of eccentric shaft on upper tool post eccentric pivot hole and the piston rod according to the adjusting range of the angle of shear, by the eccentric shaft positioner eccentric shaft position block is transferred to horizontal level, the middle maximum gauge section center of eccentric shaft this moment and the front and back eccentric segment line of centres are in level, the eccentric segment center of eccentric shaft is in plumbness with the bearing pin line of centres that is contained in the piston rod upper pin hole, connecting rod is in vertically hangs the weight that state is carrying upper tool post, on the upper tool post on plane and the upper tool post about the eccentric segment line of centres of two eccentric shafts be in level, the supporting plate that floats is concordant with plane on the upper tool post.During shear, upper tool post is descending under piston rod promotes, when upper tool post blade contact during by the shear material of short duration stop descending, this moment, eccentric shaft will clockwise rotate under the promotion of connecting rod, connecting rod and unsteady supporting plate will float downwards along with the rotation of eccentric shaft, until the piston rod end ballhead contacts fully with spherical base, thus like this active force of hydraulic cylinder namely shearing force will act directly on by piston rod end ballhead and spherical base and finish shearing work on the upper tool post.Shear completely, piston rod is up, and this moment, eccentric shaft will rotate counterclockwise first return under the drive of connecting rod, connecting rod is in vertically hang to drive the upper tool post return under the state again.When adjusting the angle of shear, on the upper tool post on plane and the upper tool post about the eccentric segment line of centres of two eccentric shafts will become heeling condition by original level, vertically hang state as keeping connecting rod still to be in this moment, the eccentric segment line of centres of two eccentric shafts just becomes hypotenuse by former horizontal right-angle side on the upper tool post, its distance just needs to increase, by the adjustment bolt of regulating the left side eccentric shaft positioner eccentric shaft on the left side is rotated counterclockwise, the adjustment bolt of regulating simultaneously the right eccentric shaft positioner clockwise rotates the eccentric shaft on the right, like this on the upper tool post about the eccentric segment center of the two eccentric shafts outer side shifting that will make progress simultaneously, its distance will increase, until being in, vertically hangs till the state by connecting rod, the supporting plate that floats during adjustment also upwards floats and holds up spherical base along with the rotation of eccentric shaft, to keep that a fixing minim gap is arranged between piston rod end ballhead and the spherical base, prevent from producing impact because of excesssive gap.
