Abstract
The utility model discloses a deflection compensation mechanism capable of detecting a hydraulic oil cylinder drive encoder, which comprises a lower die and a base, wherein an oblique wedge block combination is arranged between the lower die and the base. The deflection compensation mechanism capable of detecting the hydraulic oil cylinder drive encoder further comprises a pull rod, a hydraulic oil cylinder, a rack, a gear and an encoder, wherein a first end of the oblique wedge block combination is connected with the hydraulic oil cylinder through the pull rod, a second end of the oblique wedge block combination is connected with the rack, and the rack is connected with the encoder through the gear. The deflection compensation mechanism capable of detecting the hydraulic oil cylinder drive encoder achieves digital display of mobile distance through the encoder, the gear and the rack, and can lightly and conveniently achieve adjusting of the oblique wedge block combination.

The deflection compensation mechanism capable of detecting the hydraulic oil cylinder drive encoder changes sliding friction into rolling friction by arranging balls on the lower oblique wedge block, thereby greatly reducing frictional resistance. The deflection compensation mechanism capable of detecting the hydraulic oil cylinder drive encoder is simple in structure and extremely practical.
Description
Technical field
The utility model bender technical field is a kind of deflection compensation mechanism that drives encoder to detect with hydraulic jack specifically.
Background technology
The comprehensive utilization of bending machine die, depends on effective configuration of bending machine workbench face, and bending function is implemented and completed to bender by setting in advance with the motion process of bender oil cylinder of upper/lower die shape, size.
Due to the raising of automaticity, in the situation that the Rigidity and strength of metal forming machinery body can meet task, it is more brief better that the weight of machinery always designs.In Forging Process, often inevitably there are two defects in bender: the one, and the stressed slide block that causes of framework own produces elasticity small deformation; The 2nd, the wearing and tearing of shaping dies.The former makes work piece produce deflection deformation, cannot guarantee the total length uniformity of angle; Latter affects the linearity of work piece.
The bending forming machine of at present domestic production is a kind of to the deflection compensation of workbench is that many hydraulic jacks are embedded in to the hydraulic pressure deflection compensation in workbench riser; Another kind of by many groups, add the mechanical bending deflection that protruding voussoir forms and compensate.Many hydraulic jacks are embedded in the hydraulic pressure deflection compensation in workbench riser, it mainly adds protruding motion by lower table oil cylinder, thereby complete compensation hydraulic action, but when lower table oil cylinder carries out deflection compensation, due to the architectural feature of workbench of itself, be difficult to guarantee obtain on each aspect at processing work accurate compensation, simultaneously because needs oil cylinder compensates motion, the cost of the manufacture that is unavoidably can improve, the oil cylinder that is arranged on workbench is too many, and the strength and stiffness of workbench are had a certain impact.Another takes the form by adding protruding voussoir by many groups to compensate amount of deflection, 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, also easily expend aborning and wear and tear simultaneously.
Utility model patent " a kind of inclined-wedge type flexibility compensating device of bender " referring to Granted publication CN202155410U, comprise counterdie and base, on base, offer along its length rectangular channel, lower planker is installed in rectangular channel, longitudinal uniform installation odd number group Wedge mechanism on lower planker, each Wedge mechanism is by the wedge II of closed assembly and wedge I form successively from bottom to top, closed assembly rectangle parallels, upper planker successively on lower planker, wedge I is evenly nested on planker, counterdie lower surface is provided with screw, and the position of the corresponding screw of wedge I is provided with through hole.This technology, although adopt the deflection compensation mode of Wedge type, the numeral that can not realize displacement shows, the adjusting that realizes the combination of wedge piece that can not be easy and convenient.
Because compensation between tapered wedges is larger by the sliding friction at curved surface place, not only there is noise, easy to wear, when wedge compensates, the pulling force needing is also larger, higher to the configuration requirement of device; Also due to wedge deflection compensation, adopt the kind of drive of motor, pull bar, supporting plate, need mechanically operated parts more, cause deflection compensation precision to reduce.
Therefore, need especially a kind of deflection compensation mechanism that drives encoder to detect with hydraulic jack, solve problems of the prior art.
Utility model content
