Abstract
The utility model provides a bender lower die anti-deflection device, and relates to improvement of a bender lower die anti-deflection device coincide with the shape of a deflection line in a larger degree. The anti-deflection device is disposed between a lower die and a frame workbench, and comprises an upper cover plate, a base, an upper wedge block, a lower wedge block, and an upper wedge block driving device; the combining surfaces of the upper wedge block and the lower wedge block are respectively provided with several inclined planes with maintenance of mutual contact of surfaces and a consistent direction, inclination of the inclined plane at the middle part among the several inclined planes is larger than inclination of the inclined planes at the adjacent two sides, and inclination of the inclined planes reduces successively from the middle to the two ends; the upper wedge block driving device is fixedly connected with the end surface at one end of the upper wedge block, driving the upper wedge block to move relative to the lower wedge block, the top surface of the upper wedge block protrudes outwards, and the projection height at the middle part is higher than projection heights at the two ends; the upper cover plate is disposed on the top surface of the upper wedge block. The bender lower die anti-deflection device is advantaged by high precision, high bearing capacity, long service lifetime, etc., and is a very good choice for users with high requirement for bending precision.
Description
Technical field
The utility model relates to the improvement to bender anti-deflection apparatus structure.
Background technology
Bender is adding man-hour, because lathe rigidity factor, the chine of institute's bending can present the situation of two ends " deeply ", middle " shallow ".In the prior art, a kind of solution is proposed for this reason, as shown in Figure 4, designed a kind of device that supports counterdie, comprise upper cover plate, base, pull bar 8, several are wedge 7 down, and wedge 9 on several, by a very long pull bar 8 all last voussoirs 9 are connected into an integral body, during work by the driven by motor reductor, drive the rotation of screw rod again by the rotation of reductor, will make voussoir 9 produce displacement in the longitudinal direction after the screw rod rotation, because the voussoir gradient difference of diverse location,, go up like this and will form inconsistent on the height after voussoir 9 moves because voussoir 9 end faces are flat on every group, middle high, and both sides are just low, and the curve of Xing Chenging is not high with actual sag curve degree of agreement like this, and what can only be similar to is similar.
The utility model content
The utility model provides a kind of and the more identical bender counterdie anti-deflection apparatus of line of deflection shape at above problem.
Device of the present utility model is: be arranged between counterdie and the frame workbench, it comprises upper cover plate, base, goes up voussoir, lower wedge block and last voussoir drive unit; Be respectively equipped with on the described involutory surface of going up voussoir and lower wedge block that some mutual maintenance faces contact and towards consistent inclined-plane, the gradient on the inclined-plane, middle part on described some inclined-planes is greater than the gradient on its inclined-plane, position, adjacent both sides, successively decrease to direction of both ends successively one by one again; The described voussoir drive unit of going up is fixedly connected on the described end face of going up voussoir one end, makes to drive describedly when going up voussoir and moving with respect to lower wedge block, and the end face of last voussoir raises up, and the height of projection of middle part is greater than the height of projection at two ends; Described upper cover plate is located at described going up on the voussoir end face.
Device of the present utility model is made up of two all-in-one-piece voussoirs up and down, and the gradient on each inclined-plane, position is that the sag curve according to slide block, the finite element analysis of workbench riser designs.During work by the driven by motor reductor, drive the rotation of screw rod again by the rotation of reductor, the gradient difference of the diverse location of voussoir will make voussoir produce displacement in the longitudinal direction after the screw rod rotation, owing to will form a curve that matches with actural deflection after last voussoir moves.Adding the structure that pull bar moves with traditional one group of voussoir compares, the monoblock type mechanical compensation is because compensation point many than traditional type, and can produce whole curved surface after the compensation, so its compensated curve is relatively slicker and more sly, can be good at coincideing high conformity with the curve of the workbench deflection deformation of reality; Also have monoblock type mechanical compensation whole rigidity relatively good, can the bigger load of CBR traditional structure.But its difficulty of processing coefficient is very big, see the processing schematic diagram of whole voussoir up and down, by fixing frock, upper and lower voussoir is fixed up then with the path of numerical control machining center digital control system programming software simulation inclined-plane dimensional requirement programming feed, like this by clamping of machining center, disposable feed shapes, thereby guarantees its precision.The utlity model has advantages such as precision height, bearing capacity is strong, the life-span is longer, require very high user for bending precision, is an extraordinary selection.
