Description
Technical field
The utility model belongs to bender field, specifically, relates to a kind of bender with workbench compensation arrangement.
Background technology
Bender is a kind of machine that can carry out to sheet material bending, its structure mainly comprises support, workbench and clamping plate, workbench is placed on support, workbench is made up of base and pressing plate, base is connected with clamping plate by hinge, base is made up of seat shell, coil and cover plate, and coil is placed in the depression of a shell, and recessed top is covered with cover plate.When use by wire to coil electricity, after energising, pressing plate is produced to gravitation, thereby realizes clamping to thin plate between pressing plate and base.Owing to having adopted electromagnetic force clamping, make pressing plate can make various workpieces requirement, and can process the workpiece that has sidewall, also very easy in operation.
The mould that bender uses is to be shaped as straight line, thin-and-long, due to the support of supporting mould, the reason of slide block and workbench etc. self rigidity, it is inconsistent in workpiece total length that patrix enters the degree of depth of lower die open, the certain amount of deflection of unavoidable appearance, cause the bending angle at workpiece two ends phenomenon small in ends, broad in the middle.Raises up in the middle of patrix, in the middle of counterdie, to lower recess, cause bending angle intermediate angle problem bigger than normal after Workpiece shaping, cannot meet the requirement of bending angle.
Bender compensation arrangement uses more general, for example, Chinese Patent Application No.: 201320692863.0, the applying date: on November 06th, 2013.This utility model relates to bending machine workbench device technique field, be specifically related to bending machine workbench mechanical compensating mechanism, comprise workbench and be located at the deck plate of described workbench top, the below of described deck plate is provided with screw mandrel, the deck plate of described screw mandrel and its top be arranged in parallel, and one end of described screw mandrel is connected with motor; Between described deck plate and workbench, be provided with some upper and lower wedge groups, the even interval of described some upper and lower wedge groups arranges, and described some upper and lower wedge groups comprise some upper wedges and the some lower wedge of correspondence with it.This utility model adopts said structure, drive screw mandrel to rotate by the electric machine rotation being connected with screw mandrel, thereby the lower wedge of upper and lower wedge group is moved left and right, upper wedge moves up and down, finally realize deck plate and be level and smooth radian shape, thereby realize compensation effect, avoided workpiece angle in length range to increase phenomenon, effectively improved angle and the linear precision of bending workpieces.Visible, bender compensation arrangement very universal.
Wherein, the application of mechanical compensation mechanism is more extensive.And that the power source of bending machine workbench compensation arrangement has is a variety of, as hydraulic pressure, electronic, manually.For example, Chinese Patent Application No.: 201220622210.0, the applying date: on November 22nd, 2012.The novel independent pressurization deflection compensation mechanism of this utility model bender, has compensating cylinder, and the pressurization of its compensating cylinder and oil supply system are independent hydraulically controlled oil circuit, and are directly communicated with floor push.The problem that this utility model exists for existing bender hydraulic pressure deflection compensation, the novel independent pressurization deflection compensation mechanism of bender of design, compensating cylinder adopts independent hydraulically controlled oil circuit fuel feeding, compensatory pressure can be according to the length and the thickness step-less adjustment voluntarily that fold plate, overcome the phenomenon that compensatory pressure and master cylinder pressure are integrated mutual interference, that has greatly improved super long workpiece folds precision and production efficiency.
Bending machine workbench mechanical compensating mechanism on above patented product and existing market is simple in structure, apply more extensive, easily operation, but mostly be integrally-regulated, degree of regulation is poor, adjusting device unstable properties, can not ensure workbench to add convex curve consistent with practical distortion curve, the bending precision of workpiece is lower, in the time of the high-precision workpiece of Bending Processing, can not adjust separately, thereby affect bending precision.So can solve compensation arrangement adjusting function in the urgent need to a scheme stablizes and the not high enough problem of precision not.
