Description
Technical field
The upper tool post drive mechanism that relates to cutting sheet machine under the utility model.
Background technology
Plate shearing machine is mainly used in the metallic plate of various thickness to apply shearing force, makes sheet material separated by needed size fracture.At present, the upper tool post drive mechanism of plate shearing machine comprises upper tool post 101, the two ends of upper tool post 101 are symmetrically installed with respectively global cushion block 102, connecting rod 103 is vertically installed on global cushion block 102, on connecting rod 103, be connected with plate shearing machine cylinder 104, on connecting rod 103 and upper tool post 101, insert respectively the lateral pin 105 of pair of parallel, in lateral pin 105 both sides, by running through successively the bolt 106 of upper and lower two lateral pins 105, two lateral pins 105 are connected and fixed, the nut 107 of bolt 106 and through between the lateral pin 105 of connecting rod 103 and bolt head 108 butterfly spring 109 is set with passing between the lateral pin 105 of upper tool post 101.Because plate shearing machine need regulate cutter gap and Cutting angle, therefore, the relative plate shearing machine cylinder meeting of upper tool post deflection certain angle, thereby, the junction of oil cylinder and upper tool post should be stressed and pulling force, hydraulic shock power when the bolt connecting on lateral pin also will bear the weight of upper tool post and upper tool rest return, bolt easily produces the phenomenon of fatigue fracture, makes plate shearing machine in use have larger potential safety hazard; The nut of bolt and through between the lateral pin of connecting rod and bolt head disk spring is set with passing between the lateral pin of upper tool post, by flexibly connecting, although can alleviate to a certain extent pressure and the pulling force of oil cylinder and upper tool post junction, but, flexibly connect and can not realize real universal connection, still can cause oil cylinder to be subject to offset loading force, under long-term offset loading force effect, oil cylinder there will be oil leakage phenomenon; In addition, the blade of plate shearing machine is oblique sword structure, there will be shearing component during shearing, makes oil cylinder further be subject to the impact of offset loading force, has a strong impact on the service life of oil cylinder.
Utility model content
The utility model aims to provide a kind of oil cylinder and upper tool post of making without the upper tool post drive mechanism of rigidly connected plate shearing machine, makes the junction of oil cylinder and upper tool post main body stressed evenly.
The upper tool post drive mechanism of a kind of plate shearing machine described in the utility model, comprise upper tool post, two ends, upper tool post top are respectively arranged with master cylinder, two ends, bottom arrange respectively corresponding backhaul oil cylinder, at main oil cylinder piston boom end, by bottom cushion block, be placed in upper tool post top, backhaul oil cylinder piston rod end surface is supported on the bottom of upper tool post by top cushion block, described main oil cylinder piston boom end coordinates by spherical concave surface and the spherical convex surface mutually coincideing with bottom cushion block, backhaul oil cylinder piston boom end coordinates by spherical concave surface and the spherical convex surface mutually coincideing equally with top cushion block, on the cushion block of bottom, be provided with pilot hole, screw is tightened on main oil cylinder piston boom end through pilot hole, on the cushion block of top, be provided with equally pilot hole, screw is tightened on backhaul oil cylinder piston boom end through pilot hole, has the gap for screw activity between described screw and pilot hole.
The upper tool post drive mechanism of a kind of plate shearing machine described in the utility model, when needs regulate Cutting angle, by controlling the hydraulic-oil quantity of right side master cylinder epicoele, make upper tool post can swing to up or down corresponding Cutting angle, complete after the adjusting of Cutting angle, main oil cylinder piston bar stretches out downwards, simultaneously, backhaul cylinder piston rod is retracted, thereby upper tool post is toward descending and carry out shearing work, and after shearing, main oil cylinder piston bar is retracted, the cylinder piston rod of backhaul simultaneously protrudes upward, thereby promotes after upper tool post rises to initial position to stop.Because main oil cylinder piston bar coordinates by spherical concave surface and the spherical convex surface mutually coincideing with top cushion block with bottom cushion block and backhaul cylinder piston rod, therefore, in work and backhaul process, upper tool post can carry out swing by a small margin with spherical convex surface, the impact of the offset loading force producing while eliminating operation on master cylinder and kicker cylinder, not only can meet the adjustment requirement of cutter gap, Cutting angle, also rigging error can be down to minimumly on the impact of plate shearing machine, make lathe operation troubles rate lower; And because master cylinder and backhaul oil cylinder contact with upper tool post with top cushion block by bottom cushion block respectively, therefore, between master cylinder, backhaul oil cylinder and upper tool post without any being rigidly connected, avoided the phenomenon of bolt fatigue fracture in prior art syndeton, also made the adjusting of cutter gap, Cutting angle more flexible; Meanwhile, during plate shearing machine operation, the shearing component that its blade produces while shearing sheet material can not be delivered on oil cylinder yet, avoids oil cylinder to bear offset loading force, greatly reduces the risk of master cylinder leakage of oil, damage.The upper tool post drive mechanism of this kind of plate shearing machine is simple, easier for installation.
