Description
Technical field
The utility model relates to a kind of inclined-wedge type flexibility compensating device of bender, specially refer to a kind of be used for little tonnage bending forming machine when bending to obtaining accurate inclined-wedge type flexibility compensating device on the workbench total length.
Background technology
Effective configuration of bender work top is depended in the comprehensive utilization of bending machine die, and bender is through the bending function is implemented and accomplished to the setting in advance of mold shape, size and the motion process of bender oil cylinder up and down.
Because the raising of automaticity, can satisfy under the situation of task in rigidity and the intensity of metal forming machinery body, it is brief more good more that mechanical weight always designs.Often inevitably there are two defectives in bender in the bending process: the one, and the stressed slide block that causes of framework own produces the elasticity small deformation; The 2nd, the wearing and tearing of shaping dies.The former makes work piece produce deflection deformation, can't guarantee the total length uniformity of angle; The latter then influences the linearity of work piece.
The bending forming machine of domestic production at present is a kind of to degree of the disturbing compensation of workbench to be to be embedded in the hydraulic pressure deflection compensation in the workbench riser to many hydraulic cylinders; Another kind of then add the mechanical bending deflection compensation that protruding voussoir forms by many groups.Many hydraulic cylinders are embedded in the hydraulic pressure deflection compensation in the workbench riser; It mainly adds protruding motion through the lower table oil cylinder, thereby accomplishes the compensation hydraulic action, but the compensation of lower table oil cylinder degree of disturbing the time; Because the architectural feature of the workbench of itself; Be difficult to guarantee on each aspect, obtain accurate compensation at processing work, owing to need oil cylinder to compensate motion, the cost of the manufacturing that is unavoidably can improve simultaneously; The oil cylinder that is installed in workbench is too many, and the strength and stiffness of workbench are had certain influence.A kind of in addition taking comes amount of deflection is compensated through the form that adds protruding voussoir by many groups; With respect to the former flexibility compensating device of fluid pressure type; Can guarantee that processing work obtains compensation comparatively accurately on each aspect; Do not need oil cylinder to compensate motion, but very high to the requirement on machining accuracy of voussoir, the while is also expended easily aborning and weares and teares.
One Chinese patent application number: 200820192195.4 patent document discloses a kind of flexibility compensating device of workbench; This device carries out deflection compensation through the many groups of machineries that add protruding voussoir composition; It is characterized in that, on workbench, have the groove that twice are arranged in juxtaposition along its length, the both ends of twice groove are communicated with; One pull bar respectively is housed in the twice groove; Respectively be equipped with some on two pull bars and add protruding voussoir and head, the tail end disjunctor adds protruding voussoir, the outer end that the head end disjunctor adds protruding voussoir is drilled with screw screw rod is installed, and the screw rod outer end connects drive unit; Said each add protruding voussoir and the head, the tail end disjunctor add protruding voussoir above the circular arc cushion block respectively is housed, circular arc cushion block both sides are designed with bearing pin; The bearing pin of relative all circular arc cushion blocks all has the U-lag of vertical direction in the groove two side of workbench, and the bearing pin correspondence of each circular arc cushion block is contained in the U-lag.The upper surface that adds protruding voussoir and circular arc cushion block that is contained on the pull bar of this utility model is arc surface; Adding the upper surface of protruding voussoir and the lower surface of circular arc cushion block fits tightly; Because adding the upper surface of protruding voussoir is arc surface, the lower surface of circular arc cushion block is the plane, so machining accuracy is not very high.
The utility model content
The technical problem that solves
To the deficiency of prior art, the utility model provides the many groups of a kind of employing wedges to constitute compensation arrangements, forms a plurality of compensation points, makes the compensation point accurate more inclined-wedge type flexibility compensating device of crypto set, deflection compensation more of amount of deflection.
Technical scheme
The inclined-wedge type flexibility compensating device of a kind of bender that this practicality is new comprises upper cover plate and base, offers rectangular channel on the said base along its length; Planker is installed down in the rectangular channel; Vertically be uniformly distributed with on the said down planker odd number group Wedge mechanism is installed, each Wedge mechanism is by the wedge II of closed assembly and wedge I are formed closed assembly rectangle parallels, last planker successively on the said planker down successively from bottom to top; The voussoir I evenly is nested on the planker; Last planker mainly plays fixing to the voussoir I and limits the effect that it moves, and said upper cover plate lower surface is provided with screw, and the position of the corresponding screw of said wedge I is provided with through hole.The somewhat larger in diameter of through hole plays the effect of fixed cover plate to a certain extent in screw.
The wedge II and the superposed wedge I that are positioned at the bottom are a pair of; Form the local modulation Wedge mechanism; Each is to the inclined-plane corresponding matching of wedge; All be horizontally set, and the gradient of the wedge II between the base rectangular channel is maximum, and the gradient that is positioned at each wedge II of the base rectangular channel left and right sides is successively decreased successively.
A said end of planker down is provided with rectangular channel, and said planker down buckles through rectangular channel and hook, and said hook is provided with screw away from an end of following planker, and said hook is connected with pull bar through screw, and the overhanging end of said pull bar is equipped with reducing motor.
The driven by motor pull bar rotates; Pull bar is through linking up with traction planker generation displacement down, and the wedge II under installing simultaneously on the planker produces corresponding displacement, because the upper surface of wedge II is the inclined-plane; So the wedge II drives the wedge I again and changes on the height up and down; Because the wedge I is fixedly connected with upper cover plate, so upper cover plate can produce the above-below direction displacement with the wedge I, thereby whole device is realized the effect of deflection compensation.
Beneficial effect
(1) the utility model adopts the technical scheme of upper and lower planker and upper and lower voussoir, makes to assemble more conveniently aborning, can compensate the amount of deflection that is produced according to the workpiece of different length;
(2) because the utility model adopts many group wedges to constitute compensation arrangements, form a plurality of compensation points, make the compensation point crypto set more of amount of deflection, deflection compensation is more accurate;
(3) the utility model is simple in structure, and is simple to operate; On the kind of drive, can adopt modes such as manual or machine driving.
