Description
Technical field
The utility model belongs to bender field, specifically, relates to a kind of bender with multiple location adjusting device.
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.: 200820050288.3, the applying date: on 07 07th, 2008.This utility model provides a kind of deflection compensation mechanism for bending machine worktable easy to use, quick, accurate.Between worktable panel and workbench base plate, be provided with a series of piece group of carving along the horizontal direction of workbench; The described piece group of carving is at least carved piece and is laminated by fixedly carving piece and activity; Respectively carve piece group fixedly carve piece and workbench fixes; The activity of respectively carving piece group is driven by actuating unit after carving piece and linking together by the mode of being rigidly connected; Distribution and the form parameter of carving piece group compensate the sag curve of mould.The technique effect of this utility model is: available miniature worm reduction gear or manual driving device drive and the adjustment that links, without adjusting one by one; In the time that bender has digital control system, can carry out auto-compensation by the ram bending curve when the bending to the steel plate of varying strength, thickness, length, bending power; Can compensate accurately the different distortion in various situations.Visible, bender compensation arrangement very universal.
Wherein, the application of mechanical compensation mechanism is more extensive.For example, Chinese Patent Application No.: 201010113388.8, the applying date: on 02 14th, 2010.This invention is a kind of four-matched-inclined-wedge type flexibility compensating device of bending machine, belong to bender, it is characterized in that offering along its length rectangular channel on base, the uniform installation odd number group in compartment of terrain Wedge mechanism longitudinally in this rectangular channel, respectively organizes Wedge mechanism by closed assembly coordinates successively from bottom to top two couples totally four wedges compositions, the wedge I and the wedge II that are positioned at bottom are a pair of, form local modulation Wedge mechanism, each wedge I and wedge II are all to horizontally set, before base, screw is offered at position corresponding to the stub end of wedge I on back seat wall, the adjusting bolt being connected with each wedge I in the corresponding spinning in the outside of base wall is to realize local equalize, superposed wedge III and wedge IV are a pair of, all be longitudinal setting, form integrally-regulated Cam device, in each wedge III and hollow spacer pipe, install pull bar, in the screw of the wedge III of right-hand member, spinning regulates screw mandrel, to drive each wedge III left and right displacement, realize Full-automatic integral deflection compensation, improve bending quality 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.
