Description
Technical field
The present invention relates to metal cutting technology field, especially relate to a kind of hydraulic connecting rod plate shearing machine.
Background technology
In conventional art, the hydraulic cylinder of hydraulic connecting rod plate shearing machine is arranged on the side of plate shearing machine, link lifting is sheared by Hydraulic Cylinder, synchronising (connecting) rod drives the shearing link lifting of opposite side simultaneously, the power that hydraulic cylinder exports acts in cutting member after linkage amplifies, and becomes the shearing force of cutting member.But there is following shortcoming in said structure mode: 1) produce lifting action because hydraulic cylinder promotes connecting rod in side, therefore the side force be applied on guiding mechanism is large, larger side obviously shortened to its life-span of the guiding mechanism under power effect, and the existence of side force also have impact on shear precision.2) angle of shear cannot be met by the multi-connecting-rod mechanism of Driven by Hydraulic Cylinder and adjust the needs changed to adapt to sheet metal thickness.
Summary of the invention
The object of the invention is to overcome the shortcoming existed in prior art, there is provided a kind of side force little, angle of shear size is adjustable to be applicable to the hydraulic connecting rod cutter that different-thickness sheet shearing needs, the technical scheme adopted is: a kind of novel hydraulic connecting rod cutter, comprise frame, knife rest shaft portion and hydraulic-driven part, described knife rest shaft portion comprises lower slide, described hydraulic-driven part comprises active force hydraulic cylinder, it is characterized in that: described knife rest shaft portion also comprises shearing connecting rod and down cut connecting rod, the lower end of described upper shearing connecting rod and the upper end of down cut connecting rod all with the piston hinge of described active force hydraulic cylinder, the upper end thereof of described upper shearing connecting rod is on described lower slide, the lower end of described down cut connecting rod is hinged in described frame.
Technical characteristic of the present invention also has: described active force hydraulic cylinder is an ears ring hydraulic cylinder, two earrings of described ears ring hydraulic cylinder respectively with described upper shearing connecting rod and the down cut rod hinge connection of corresponding side.
Technical characteristic of the present invention also has: described hydraulic-driven part also comprises the auxiliary hydraulic cylinder be hinged in described frame, and the piston rod of described auxiliary hydraulic cylinder is hinged on down cut connecting rod.
Technical characteristic of the present invention also has: described auxiliary hydraulic cylinder is ears ring hydraulic cylinder, and an earrings of described ears ring hydraulic cylinder is hinged in described frame, and another earrings is hinged on described down cut connecting rod.
Technical characteristic of the present invention also has: the rod chamber of described active force hydraulic cylinder is connected with the rodless cavity of described auxiliary hydraulic cylinder and formed serial oil cylinders.
Beneficial effect of the present invention is: this cutter changes the installation site of active force hydraulic cylinder, thus the side direction avoiding active force hydraulic cylinder in prior art to install the side force that causes large and then affect the problem of guiding mechanism service life and shear precision; The use of auxiliary hydraulic cylinder limits the unnecessary free degree of bar linkage structure, the adjustment of the control realization angle of shear of simultaneously connect with auxiliary hydraulic cylinder by active force hydraulic cylinder topping up and tapping; This cutter has that side force is little, the angle of shear is adjustable, and shear precision is high, the advantage of long service life.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention, and wherein 1 is frame, and 2 is upper tool posts, and 3 is lower slides, and 4 is upper shearing connecting rods, and 5 is down cut connecting rods, and 6 is ears ring auxiliary hydraulic cylinders, and 7 is ears ring active force hydraulic cylinders.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.The invention discloses a kind of novel hydraulic connecting rod cutter, comprise frame 1, knife rest shaft portion, ears ring active force hydraulic cylinder 7, ears ring auxiliary hydraulic cylinder 6, knife rest shaft portion, under ears ring active force hydraulic cylinder 7 and ears ring auxiliary hydraulic cylinder 6 drive, realizes lower cutter to the shearing of sheet material by the knee-action of lower slide 3.
Knife rest shaft portion comprises shearing connecting rod 4, down cut connecting rod 5, upper shearing connecting rod 4 upper end thereof is on lower slide 3, down cut connecting rod 5 lower end is hinged in frame 1, and the earrings of upper shearing connecting rod 4 lower end, down cut connecting rod 5 upper end, ears ring active force hydraulic cylinder 7 is hinged.Like this, when the piston action of active force hydraulic cylinder 7, be applied to that left side is upper to shear on connecting rod 4 down cut connecting rod 5 lateral force sheared on connecting rod 4 down cut connecting rod 5 on lateral force and right side and offset, thus reduce side force.
Two earrings of ears ring auxiliary hydraulic cylinder 6 respectively with frame 1 and hinged in the middle part of side down cut connecting rod 5 arbitrarily, limit and both sides are sheared connecting rod 4 free degree unnecessary with down cut connecting rod 5 when the piston action of ears ring active force hydraulic cylinder 7, make lower slide 3 with the piston emersion of ears ring active force hydraulic cylinder 7 and regain and rise and decline.
Ears ring active force hydraulic cylinder 7 with the connected mode of ears ring auxiliary hydraulic cylinder 6 is: the rod chamber of ears ring initiatively hydraulic cylinder 7 is connected with the rodless cavity of ears ring auxiliary hydraulic cylinder 6 formation serial oil cylinders, hydraulic oil enters the rodless cavity of ears ring active force hydraulic cylinder 7 thus lifts and push away on both sides and shear connecting rod 4, down cut connecting rod 5, and drive lower slide 3 action, hydraulic oil enters the rod chamber of ears ring auxiliary hydraulic cylinder 6 thus connecting rod 4 is sheared in contraction both sides, down cut connecting rod 5 enters the backhaul stage, hydraulic oil enters series connection oil pipe and series connection oil pipe has drained the oil the adjustment of the angle of shear to adapt to the sheet material of different-thickness.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited only to above-mentioned citing, and the change that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also belong to protection scope of the present invention.
