Description
Technical field
The utility model relates to numerical control machine tool field, particularly relates to a kind of numerical control bender deflection compensation mechanical device.
Background technology
Existing numerical control bending lathe often has the plate being required that processing bending length is larger in sheet metal component Bending Processing, this type of plate is when Bending Processing, because the frame for movement of upper/lower die and mechanical characteristic cause upper and lower mould to produce the larger deflection deformation of elasticity in the position that moment of flexure load is large, this distortion makes the subsides mould rate of plate in Bending Processing reduce, the situation that after the bending of generation plate, bent angle is uneven thus, even can cause the excessive generation waste product of bent angle deviation.For addressing this problem, existing bender adopts electrical-control hydraulic flexibility compensating device, such device has one to three compensating hydraulic cylinder to be positioned at workbench bottom usually, during work, hydraulic cylinder acts directly on workbench and makes workbench produce elastic deformation for compensating the deflection deformation of counterdie mould, the method compensated position distance deflection deformation location comparison is far away and only have one to three compensating hydraulic cylinder to adopt point type to compensate, spacing is large, so it is larger to compensate blind area, if increase compensating hydraulic cylinder, the riser intensity under workbench can be made to reduce, big-and-middle-sized bender will be met and adding the high accuracy bending requirement of man-hour to deflection compensation.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, can provide the device of good linear numerical control bender deflection compensation.
The technical solution of the utility model is: a kind of numerical control bender flexibility compensating device, comprise deflection compensation wedge, deflection compensation base, lower mould bottom plate and fluid pressure drive device, described deflection compensation wedge is fixed on deflection compensation base, deflection compensation wedge is right angle halfpace, fits assemble with deflection compensation base; The side that deflection compensation wedge is thicker contacts with hydraulic piston, and thinner side contacts with spring cushion block; Hydraulic piston end setting pressure container; Outside spring cushion block and spring interface; The opposite side of described spring is equipped with spring anchor block.
Preferably, the side that described deflection compensation wedge is thinner is processed with pectination gap.
Preferably, described deflection compensation wedge two ends are fixed by screws on deflection compensation base.
Preferably, deflection compensation wedge top is also coated with lower mould bottom plate.
Preferably, described pressure vessel is connected with promotion piston, promotes described hydraulic piston and outwards moves.

Detailed description of the invention
The technological means realized to make the utility model, technical characteristic, utility model object and technique effect are easy to understand, and below in conjunction with concrete diagram, set forth the utility model further.
As shown in Fig. 1 ~ 7, deflection compensation frame for movement module 1 is arranged on the workbench 2 of digital bender, and it comprises deflection compensation wedge 11 and lower mould bottom plate 10, and described deflection compensation wedge 11 is placed between deflection compensation base 13 and lower mould bottom plate 10.Be processed with pectination gap 111 in the thinner side of deflection compensation wedge 11, this purpose of design is the moment of flexure stress reducing to produce in deflection compensation process, also can reduce the operating pressure of hydraulic oil, have energy-saving and cost-reducing effect with this.Respectively there is a deflection compensation wedge retaining thread hole 112 at the two ends of this deflection compensation wedge 11, for using screw 16, deflection compensation wedge being fixed on deflection compensation base.The side that deflection compensation wedge 11 is thicker contacts with hydraulic piston 141; The side thinner at deflection compensation wedge 11 contacts with spring cushion block 121.Spring 123 will have certain pretightning force when assembling, so that after the unloading of deflection compensation hydraulic coupling, deflection compensation wedge 11 can make its elastic deformation reset under the effect of recoil of spring power again.
When deflection compensation frame for movement module 1 is started working, the oil-in of pressure vessel 15 (hydraulic cylinder) enters pressure oil, pressure oil promotes piston rod 142 and piston 141 outwards moves, piston 141 promotes again deflection compensation wedge 11 and moves along inclined-plane, and this Kinematic Decomposition is the motion in vertical and horizontal both direction.The displacement of in the vertical direction is for regulating the size of deflection compensation amount, and the displacement in horizontal direction is Compress Spring 123 then.When deflection compensation frame for movement module completes deflection compensation work, pressure oil is return from the oil-in of pressure vessel (hydraulic cylinder) 15, pressure reduces, now the screen resilience promotion deflection compensation wedge of spring 123 moves to the direction resetted, piston rod 142 and piston 141 are also pushed, until deflection compensation wedge 11 resets completely to pressure vessel (hydraulic cylinder) 15 inside.Lower mould bottom plate 10 covers on deflection compensation wedge 11, can alleviate the direct wearing and tearing of counterdie to deflection compensation wedge 11.
Also will be clamped when deflection compensation frame for movement module is started working for improving stable precision lower mould bottom plate 10, the piston 17 that under duty, lower mould bottom plate 10 is hydraulically controlled clamps.
Pressure vessel (hydraulic cylinder) and deflection compensation base use screw 18 to be connected.
Be only the utility model preferred embodiment in sum, be not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of the utility model claim change and modify, and all should belong to technology category of the present utility model.
