Abstract
The utility model relates to a manual-regulation wedge block compensation-type workbench of a numerical-control plate bending machine. The manual-regulation wedge block compensation-type workbench of the numerical-control plate bending machine comprises a compensation groove table, a base plate, adjusting screws, a plurality of upper wedge blocks and lower wedge blocks corresponding to the upper wedge blocks, wherein the upper wedge blocks and the lower wedge blocks are arranged in a groove in the bottom of the compensation groove table, the base plate is fixedly connected with the compensation groove table through screws, and the adjusting screws penetrate through the compensation groove table to be connected with nuts embedded into the upper wedge blocks through threads. The mechanical compensation workbench is adopted for the manual-regulation wedge block compensation-type workbench of the numerical-control plate bending machine to replace a traditional hydraulic compensation device, therefore, space and cost are saved, the manual-regulation wedge block compensation-type workbench of the numerical-control plate bending machine is convenient to machine, capable of being conveniently adjusted by a user, high in compensation accuracy and applicable to machines small in span of the bending machine workbench and small in work pressure.
Description
Technical field
The utility model relates to the compensation workbench of hand adjustment voussoir for a kind of digital control plate bending machine, is applicable to the bending machine workbench span less, and the type that operating pressure is less, belong to the bender technical field.
Background technology
Plate bending machine is a kind of use sheet machining apparatus widely.By using the simplest Bending Mould, adjust the dark distance of pressure of slide block, carry out the bending and molding of various angles, bending goes out various complex parts.The counterdie of bender is arranged on the sill of workbench, and patrix is arranged on slide block.In the course of work, the slide block of bender is subject to a uniform load made progress, and workbench can be subject to a downward uniform load, and under the effect of uniform load, slide block and workbench all will be along being subject to force direction to produce deflection deformation, thereby produce amount of deflection.The generation of amount of deflection makes patrix and counterdie distance, the pressure in length range that variation all occur.Middle part is because of the reason of amount of deflection, and the moulding angle of plate workpiece can be larger than two, and along with workpiece is longer, this deflection deformation is also larger.Simultaneously, being accompanied by the strength of materials that affects load increases, or plate thickens, and all will cause the angular error of workpiece in length range to increase, and badly influences angle and the linear precision of bending workpieces.
Plate bending machine often adopts the compensation hydraulic technology at present, it is comprised of one group of oil cylinder be arranged in lower table, the position of each compensating cylinder, size are to design according to the sag curve of slide block, workbench finite element analysis, the projection of riser compensation in realizing by the relative displacement between rear three risers in front, can make work top is continuous, level and smooth deformation curve, can access desirable bending workpieces.But use for a long time hydraulic oil may be mixed with foreign material, affect the operating accuracy of hydraulic proportion valve, increase the error of machining accuracy, and the oil leakage also can pollute.
The utility model content
For above-mentioned defect, the purpose of this utility model is to solve the existing bender above shortcomings that adopt the compensation hydraulic technology, provide that to be applicable to the workbench span less, the type that operating pressure is less, easy to adjust, compensation precision is high, improves the compensation workbench of a kind of digital control plate bending machine hand adjustment voussoir of bending workpieces quality.
The technical scheme that the utility model adopts for this reason is: comprise compensation groove platform, base plate, adjustment screw, some upper voussoirs and the lower wedge block corresponding with it, described some upper voussoirs and lower wedge block are arranged in the groove of compensation groove platform bottom, base plate is fixedly connected with the compensation groove platform by screw, and adjustment screw is connected with the nut thread in embedding upper voussoir through the compensation groove platform.
The quantity of described some upper voussoirs and lower wedge block is the 9-10 section.
Every segment length of described upper voussoir and lower wedge block is 100-140mm.
Being provided with disk spring in described base plate is enclosed within on screw.
Being provided with wave washer between described adjustment screw and compensation groove platform is enclosed within on adjustment screw.
The utility model has the advantages that: the utility model by the compensation groove platform at bender, arrange segmentation some on voussoir and lower wedge block, upper voussoir is regulated through adjustment screw, make its segment distance that slides along the inclined-plane corresponding with lower wedge block, simulation produces is out of shape contrary predeformation with lathe, produce broad in the middle, distortion small in ends, thereby the distortion of compensation bending machine workbench and slide block, guarantee bending precision, the hydraulic compensating device that has replaced existing bender, space and cost have been saved, easy to process, and easy to adjust, compensation precision is high, be applicable to the bending machine workbench span less, the type that operating pressure is less.
The accompanying drawing explanation
Fig. 1, Fig. 2 are structural representations of the present utility model.
Fig. 3 is the cutaway view of the A-A in Fig. 1.
Fig. 4 is the cutaway view of the B-B in Fig. 2.
In figure, 1 is compensation groove platform, the 2nd, base plate, the 3rd, adjustment screw, the 4th, upper voussoir, the 5th, lower wedge block, the 6th, screw, the 7th, nut, the 8th, disk spring, the 9th, wave washer.
The specific embodiment
Further illustrate in conjunction with the accompanying drawings and embodiments the utility model, the utility model comprises compensation groove platform 1, base plate 2, adjustment screw 3, some upper voussoirs 4 and the lower wedge block 5 corresponding with it, described some upper voussoirs 4 and lower wedge block 5 are arranged in the groove of compensation groove platform 1 bottom, base plate 2 is fixedly connected with compensation groove platform 1 by screw 6, and adjustment screw 3 is threaded with the nut 7 in embedding upper voussoir 4 through compensation groove platform 1; Upper voussoir 4 and lower wedge block 5 are the segmentation voussoir, every segment length is 125mm, 10 sections altogether, upper voussoir 4 can slide along the inclined-plane of lower wedge block 5, being provided with disk spring 8 in base plate 2 is enclosed within on screw 6, be provided with wave washer 9 between adjustment screw 3 and compensation groove platform 1 and be enclosed within on adjustment screw 3, disk spring 8 and wave washer 9 mainly play the effect of eliminating gap.
When bender is worked, can produce broad in the middle, spill deformation small in ends, by manual rotation adjustment screw 3, adjustment screw 3 can drive upper voussoir 4 segment distance that slides along the inclined-plane of lower wedge block 5 by pulling the nut 7 embedded in upper voussoir 4, go up the voussoir 4 capable compensation of a section shift-in that moves up simultaneously, the number of turns difference of adjustment screw 3 rotations, the compensate for displacement amount that moves up is also different, adjustment screw 3 by each section upper voussoir 4 that be rotatably connected, simulation produces is out of shape contrary predeformation with lathe, produce broad in the middle, distortion small in ends, play the effect of compensation distortion.
