The invention relates to a flexivity resisting device of a numerical control bending machine. The flexivity resisting device of the numerical control bending machine is arranged on a worktable of the numerical control bending machine and consists of a base, a top slab, a plurality of oblique wedge mechanisms arranged inside the base, an adjusting bolt for driving the oblique wedge mechanisms and a drive mechanism; screw threads with opposite rotating directions are arranged on the adjusting bolt from the middle part to the two ends respectively; a plurality of the oblique wedge mechanisms comprise upper oblique wedges and lower oblique wedges; the lower oblique wedges are provided with screw thread holes matched with the screw threads of the adjusting bolt; the upper oblique wedge and the lower oblique wedge are alternately connected with the screw threads with the positive rotating direction and the opposite rotating direction of the bolt respectively; the bevels of the lower oblique wedges face towards the end part of the adjusting bolt; the underside of the upper oblique wedge is matched with the upside of the lower oblique wedge; the top surface of the lower oblique wedge is contacted with the underside of the top slab; and one end of the adjusting bolt is connected with the drive mechanism. The flexivity resisting device can ensure processing precision of the junction surface and effectively overcome the disadvantages of shallow bending in the middle part and deep bending at two ends of a processed piece.
Description
Technical field
The present invention relates to the anti-deflection apparatus of numerical control bender, relate in particular to a kind of anti-deflection apparatus that can carry out the bender of deflection adjusting according to load.
Background technology
At present, because the raising of automaticity, can satisfy under the situation of task in the rigidity and the intensity of press body, the weight of machinery always designs brief more well more.At present big inertia design progressively is eliminated, and machine construction is more and more lighter and handier, and rack construction is brief, and this has greatly reduced the cost of machine.But this has also brought some technical problems, and in use, the elastic deformation of middle part fovea superior can appear in slide block.Make work piece deflection deformation occur.For example, the large-tonnage bender, reason owing to installation or machinery equipment self rigidity, work piece bending part linearity, the uneven phenomenon of angle appear, two ends are rolled over deeplyer, and the middle part is because the slide block deformation reason, and folding line is more shallow, make work piece deflection deformation occur, can not meet the requirement of processing.Thereby strengthen machine rigidity and intensity if address this problem to take to gain in weight, obviously can not meet the requirement of modern processing manufacturing industry.
Summary of the invention
The invention provides and a kind ofly can overcome slide block distortion, and can regulate the anti-deflection apparatus of the bender of deflection in real time according to load to the bending precision influence.
Technical scheme of the present invention is: it is arranged on the bender workbench, it by base, top board, be arranged on some Wedge mechanisms in the base, the adjusting screw(rod), the driving mechanism that drive Wedge mechanism form; Adjusting screw(rod) is respectively equipped with the opposite screw thread of rotation direction by the middle part to two ends; Some Wedge mechanisms comprise wedge, following wedge, and declivity wedges the screwed hole adaptive with the adjusting screw(rod) screw thread, are connected at interval respectively on the screw thread of positive and negative rotation direction of screw rod, and the inclined-plane of following wedge is towards the adjusting screw(rod) end; Last wedge bottom surface is adaptive with following wedge end face, the bottom surface of end face contact top board; One end of adjusting screw(rod) connects driving mechanism.
Be provided with positioning sleeve between the wedge under described.
Described going up between wedge end face and top board bottom surface is connected by guide chute mechanism.
The gradient of described some wedges progressively reduces from inside to outside with respect to the installation site on adjusting screw(rod).
Bender of the present invention is when bending is worked, because machine rigidity or stability, the distortion to fovea superior can appear in the slide block middle part.Therefore be provided with device of the present invention in the counterdie bottom, the deflection during in advance according to bending is regulated apparatus of the present invention in advance, makes counterdie slightly be convex, makes the counterdie middle part produce distortion upwards.The distortion that this distortion of lower table has produced when having offset patrix and counterdie matched moulds on the lathe slide block has guaranteed the precision of processing faying face to have overcome the work piece middle part defective that bending is shallow, the two ends bending is dark effectively.

The specific embodiment
As Fig. 1,2, the present invention is arranged on the bender workbench, it by base 2, top board 1, be arranged on some Wedge mechanisms in the base 2, the adjusting screw(rod) 5, the driving mechanism that drive Wedge mechanism form; Adjusting screw(rod) 5 is respectively equipped with the opposite screw thread of rotation direction by the middle part to two ends; Some Wedge mechanisms comprise wedge 3, following wedge 4, and following wedge 4 is provided with and the adaptive screwed hole of adjusting screw(rod) 5 screw threads, are connected at interval respectively on the screw thread of positive and negative rotation direction of screw rod 5, and the inclined-plane of following wedge 4 is towards adjusting screw(rod) 5 ends; Last wedge 3 bottom surfaces are adaptive with following wedge 4 end faces, the bottom surface of the end face contact top board 1 of last wedge 3; One end of adjusting screw(rod) 5 connects driving mechanism.Driving mechanism comprises decelerator 6, servomotor 7.
Be provided with positioning sleeve 8 between the following wedge 4.
Be connected by guide chute mechanism 9 between last wedge 3 end faces and top board 1 bottom surface.
The gradient of some wedges progressively reduces from inside to outside with respect to the installation site on adjusting screw(rod).
User mode of the present invention such as Fig. 3, it is installed on the workbench 10.Workpiece size according to input, digital control system calculates the load of bending automatically, thereby draw the deflection that slide block produces, again by calculating, issue instructions to servomotor 7, drive adjusting screw(rod) 5 and rotate, Wedge mechanism is along the X-axis axially-movable, the Y that wedge produces makes top board 1 produce Y to distortion to motion.Owing to need the deformed shape of top board 1 to be convex, need select the gradient of each single tapered wedges group of Wedge mechanism according to the deflection of slide block.Specifically, on X-direction by in outwards settle 6 pairs Wedge mechanism, Y to deflection Y1～Y6 adaptive with the slide block deflection of actual bending load generation.
