Description
Technical field
The utility model relates to the plant equipment field, relates in particular to a kind of pressure bender.
Background technology
At present, the plate bending workpieces progressively develops towards the trend of high accuracy, many kinds, and particularly automobile industry, container industry and sheet material production and processing industry also certainly will be towards the high-precision future developments of high rigidity as related bending equipment in plate forming.The major function of bender is plate compressing by mold shape, and in compressing process, the rigidity intensity of self cantilever beam of bender plays conclusive effect to the formed precision of workpiece and the uniformity of size.
but present bender version mostly is open cantilever beam structures, i.e. so-called " C " type structure, when the bender of this open cantilever beam structures is worked, can produce certain deflection deformation under the effect of downforce, downforce is larger, the rigid deformation degree just more arrives, the amount of deflection that produces is also larger, also will affect self rigidity of lathe and the formed precision of workpiece, especially for formed precision and the larger workpiece of dimensional accuracy, often can not satisfy design standard, prior art is in order to satisfy the design standard of workpiece, adopt the mode that increases the cantilever beam size to increase the rigidity of cantilever beam, whole Whole Equipment size increased, and manufacturing cost increases, it is heavy that whole equipment becomes, be difficult to mobile and maintenance, in addition, the most employing of the upper mode slider of heavy duty machine tools and hydraulic cylinder piston is rigidly connected, in the downslide process, if two hydraulic cylinders are due to generation displacement difference such as confession shortages of oil, it is two-piston bar Asynchrony, cause hydraulic cylinder piston flexural deformation in forcing folding process, affect the service life of hydraulic cylinder.
Summary of the invention
The technical problems to be solved in the utility model is for the existing weak point of prior art, provides that a kind of simple in structure, with low cost, equipment rigidity is strong, the shaping workpiece precision is high, dimensional accuracy is high, the pressure bender of long service life.
technical solution of the present utility model is, following a kind of pressure bender is provided, comprise: support, the column that is connected with support, the hydraulic cylinder at column top and slide block, workbench on support and electric control system, described column comprises that two groups four lay respectively at the left and right sides, described column is two composition O type memorial archway formula structures on the same group, the column top of the two groups of O type memorial archway formula structures in described left and right is equipped with the hydraulic cylinder of connection sliding block, described hydraulic cylinder is fixed on left and right pillar by step surface and screw, be provided with flexible connecting device between the piston rod head of described hydraulic cylinder and slide block.
Adopt above technical scheme, about the C type open type bender that will have, two columns respectively increase the bender that a root post forms O type memorial archway formula structure, and wherein two groups of former and later two columns that are designed to respectively the split formula in left and right, make manufacturing and installation process more for convenience; Hydraulic cylinder adopts the mode of step and screw lock to fix, make whole hydraulic cylinder in Forging Process not only only by bolt-locking, step also can provide barrier force, has avoided bolt to be subject to such an extent that shearing force is excessive and rupture; Increase flexible connecting device at piston rod head and slide block connecting portion, effectively avoid owing to causing piston rod to move the stressed flexural deformation phenomenon of the asynchronous piston rod that causes, the service life of having improved hydraulic cylinder for shortage of oil.
As preferably, described flexible connecting device comprises that head is the piston rod of cambered surface, be arranged on the cambered surface pad on piston rod, described piston rod head is offered link slot and is connected with slide block by straight pin, described link slot bottom is arc surfaced, is provided with the cambered surface pad between described link slot bottom and slide block.
Adopt above technical scheme, described flexible apparatus is for processing link slot on piston rod, slide block is deep in link slot, pass by straight pin and set in advance the pin sky of being connected with slide block at piston rod and connect, the rotational freedom of this connected mode between slide block and piston rod is not limited, other frees degree all are limited, and the cambered surface pad is set, material is rubber, adopt the technical program, even if there is the situation of asynchronous operation within the specific limits in two of left and right hydraulic cylinder, can not cause the stressed flexural deformation of piston rod yet.
As preferably, two groups of columns of described hydraulic cylinder and left and right on the same group before and after between two root posts by bolt and drift fixing and locking.Adopt the technical program, can regulate thickness to the adjusting of drift in the certain size scope and cause error to adapt to processing, make the upper stage terrace of the front column of left and right memorial archway and rear column simultaneously stressed, rigidity and the stability of raising complete machine frame.
