Abstract
The invention relates to a positioning device used in bending forming of airplane sheet metal. The positioning device comprises a fastening bolt, a sliding panel and a baseplate; the upper surface of the baseplate is semicircular; a through semicircular sliding groove is formed on the upper surface of the baseplate; the semicircular upper surface of the baseplate is concentrically arranged with the semicircular sliding groove; the sliding panel is a sector and is provided with a circular arc boss concentrically arranged with the sector; the circular arc boss is embedded in the sliding groove and can slide in the sliding groove; and the fastening bolt passes through the circular arc boss concentrically arranged with the sector, and is used for fastening the sliding panel and the baseplate. The invention is mainly used for positioning parts in bending forming by a bending machine, solves the problem of difficult positioning in press-brake forming of sheet metal parts, and improves the working efficiency.
Description
Technical field
The present invention relates to the positioner of bending and forming in a kind of sheet metal shaping.
Background technology
Positioning device used in bending forming of sheet metal is to be used for a kind of technological equipment of lock compression set position part in sheet metal bending and forming process, and the design applicability of positioner and versatility directly have influence on Aircraft Sheet Metal Parts production cost and production efficiency.Positioner on existing bender can only meet a kind of locate mode of form, it relies on bender to carry rear positioning baffle and the brake-press counterdie positions, its shortcoming is: it is parallel with the part bending center line that the part of energy press-brake forming must have an edge, could lean on rear positioning baffle to determine the position of part, so the part type of energy press-brake forming is more single.But the most more complicated of aviation sheet metal part shape, an edge of part not necessarily with the part bending line parallel.Many sheet metal parts are straight line crimps, originally can use and use the bender press-brake forming, but take the hydroforming of rubber pocket hydraulic press owing to locating, and production cost is high and production efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is: a kind of device that part itself does not have edge part orientation problem parallel with the part bending center line that solves is provided.
Technical scheme of the present invention is: a kind of positioning device used in bending forming of sheet metal, and described positioner comprises fastening bolt, sliding panel, base plate; Described plate upper surface is for semicircle and a penetrating semicircle sliding tray is arranged, and plate upper surface is semicircle concentric with semicircle sliding tray; Described sliding panel is a sector, and a circular arc boss concentric with sector arranged; The circular arc boss is embedded in sliding tray and can slides; Fastening bolt is through sector circular arc boss, for fastening sliding panel and base plate.
Beneficial effect of the present invention is: positioner of the present invention in operating process, by unclamping fastening bolt, mobile sliding panel that can be easily and effectively, regulate the orientation angle needed, therefore can meet the lock compression set position problem of different parts, improve operating efficiency, reduce production cost.

Fig. 2 is the profile of positioning device used in bending forming of sheet metal along A-A;
Fig. 3 is that positioning device used in bending forming of sheet metal is installed on the schematic diagram on bender;
In figure, 1-circular arc boss, 2-bender backboard, 3-part, 4-bender lower die, 5-fastening bolt, 6-sliding tray, 7-sliding panel, 8-base plate, 9-bending center line.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Fig. 1 is the positioning device used in bending forming of sheet metal structural representation, and Fig. 2 is the profile of positioning device used in bending forming of sheet metal along A-A.
Fig. 3 is that positioning device used in bending forming of sheet metal of the present invention is installed on the schematic diagram on bender.Carry out in the part 3 of bending and forming the neither one edge parallel with bending center line 9, according to existing bending and forming method locate mode, can't carry out press-brake forming, but use positioner of the present invention just can address this problem.Positioner of the present invention is done semicircle slidable adjustment and is gone out different angles on base plate 8 by sliding panel 7.In use, positioner is installed on the front surface of bender lower die 4, guarantees that the upper plane of base plate 8 is concordant with bender lower die 4 upper surfaces.Part 3 is placed on positioner base plate 8, and part bending center line 9 overlaps with the center line of bender lower die 4; Regulate the distance of bender backboard 2 apart from the bender lower die center line, part 3 terminations are withstood on bender backboard 2; Regulate the angle of sliding panel 7 in positioner, make it to be adjacent to a side of part, the fastening bolt 5 of screwed in place device.Lathe starts, and upper die of bending machine moves down, and is pressed on part 3, under the common effect of upper die of bending machine and bender lower die 4, makes part along 9 bendings of bending center line.
