The specific embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
The structural representation of the positioner of the bender that Fig. 3 provides for the utility model embodiment; Understand for convenience the structure that also shows bender in Fig. 3; As shown in Figure 3, the positioner of this bender comprises: positioning table 2 ', slide bar 3 ', slide block 4 ', first connecting rod 5 ', second connecting rod 6 ', depression bar 7 ', alignment pin 9 '.Wherein, positioning table 2 ' be installed on bender; Slide bar 3 ' with positioning table 2 ' be fixedly connected with; Slide block 4 ' with slide bar 3 ' be slidably matched, slide block is provided with locating hole on 4 ' one end, alignment pin 9 ' through locating hole, for workpiece to be processed 10 ' on through hole match; First connecting rod 5 ' two ends respectively with slide block 4 ' and second connecting rod 6 ' one end be rotatably connected (as first connecting rod 5 ' upper end by hinge 13 ' with second connecting rod 6 ' one end be rotatably connected, like this can be so that realize second connecting rod 6 ' with first connecting rod 5 around hinge 13 ' rotation), second connecting rod 6 ' two ends between be provided with center of rotation 11 '; Depression bar 7 ' with the upper cutting die 8 of bender ' be fixedly connected with, for drive second connecting rod 6 ' rotate around it center 11 ' rotation when moving down.
Above-mentioned center of rotation 11 ' implementation have multiple, as: center of rotation 11 ' with the first connector 12 ' hinged, the first connector 12 ' with slide bar 3 ' be fixedly connected with, for another example: center of rotation 11 ' hinged with the second connector (scheming not shown), the second connector and positioning table 2 ' be fixedly connected with.In addition, the implementation of depression bar 7 ' drive when moving down second connecting rod 6 ' rotate around it center 11 ' rotation also has multiple, as: second connecting rod 6 ' the other end be positioned at depression bar 7 ' under, when depression bar 7 ' move down with second connecting rod 6 ' the other end contact to exert pressure, and then promote second connecting rod 6 ' rotate around it center 11 ' rotation; For another example second connecting rod 6 ' the other end and depression bar 7 ' be slidably connected, when depression bar 7 ' move down, drive second connecting rod 6 ' the other end to the depression bar 7 ' left end shown in Fig. 3 ', slide and along with depression bar 7 ' integral body moves down.
In the unshowned mode of a kind of figure, positioning table 2 ' can be set to the adjustable form of horizontal direction and vertical direction position, concrete, positioning table 2 ' comprise body and detent mechanism; Slide bar 3 ' be fixedly connected with body, body is installed on by detent mechanism on the crossbeam of bender, and detent mechanism comprises support and dog screw, and body is fixed on support through bolt, and support is fixed on the crossbeam of bender through dog screw.Like this, adjusting by positioning table 2 ' horizontal level can realize dynamic adjustment orientation distance, with adapt to the workpiece to be processed 10 of bending hole and bending line different distance ', avoid, for the frequent positioner of changing of dissimilar workpiece to be processed 10 ' needs, reducing workload and reducing equipment cost.
The course of work of the positioner of above-mentioned bender be summarized as follows (take second connecting rod 6 ' the other end be positioned at depression bar 7 ' under explain as example): first by adjust positioning table 2 ' installation site, can make the lower cutting die 1 of alignment pin 9 ' press close to ', by workpiece to be processed 10 ' (as steel plate) can be sent to lower cutting die 1 ' on, adjust workpiece to be processed 10 ' position, when bending hole and alignment pin 9 ' while aliging, alignment pin 9 ' fall into bending hole to realize workpiece to be processed 10 ' location, due to 2 principles that determine a line, on lower cutting die 1 ' rear (left side shown in Fig. 3), the above-mentioned positioner of two covers is set, by two alignment pins 9 ' bending hole, two of location, can reach the object of bending hole, accurate location and bending line distance, when upper cutting die 8 ' in the process pressing down, band dynamic pressure plate 7 ' push down second connecting rod 6 ' around center of rotation 11 ' rotate counterclockwise, first connecting rod 5 ' around hinge 13 ' rotation, and with hinge 13 ' do plane motion, and then promote slide block 4 ' along slide bar 3 ' do ascending motion, can realize like this in Forging Process (upper cutting die 8 ' the process of depressing in), can automatically exit alignment pin 9 ', prevent bending hole and alignment pin 9 ' interference, when upper cutting die 8 ' rising (leaving), second connecting rod 6 ' upper end be released, second connecting rod 6 ' under the Action of Gravity Field of slide block 4 ' and alignment pin 9 ' wait is around center of rotation 11 ' clockwise rotate, (with upper cutting die 8 ' interlock) under automatic pressing again, self adaptation is pressed close to lower cutting die 1 ' with the pending work of bending next time.
Be understandable that, can by adjust positioning table 2 ' horizontal direction position (or slide block 4 ' position and size) just can meet the demand of dissimilar (bending hole from bending line apart from different) workpiece to be processed, to workpiece to be processed 10 as shown in Figure 4 ', distance d very little (as 28mm) between its bending hole a and bending line b, also can effective location; By adjust alignment pin 9 ' size can meet the positioning requirements in dissimilar bending hole.
The utility model embodiment alignment pin positions bending hole from workpiece to be processed top, it is not subject to the impact of lower cutting die, can carry out effective location to the workpiece to be processed that between bending hole and bending line, distance is less, improve assembled powder tank FG200F.4.11-1 bending precision, meet hole dimension required precision, avoided original burr location and caused the dimensional discrepancy of hole and bending line to reach the shortcoming of 2mm; The technological requirement that can adapt to different orientation distances by changing the slide block of different size, can be fitted in the location hole in lower cutting die plane in location, be adapted to the operating mode of the multiple distance of bending hole and bending line, and alignment pin can be thrown off from workpiece to be processed top in the course of the work automatically, prevents from interfering with workpiece.
The utility model also provides the unshowned a kind of bender of figure, it comprise cutting die 8 ', lower cutting die 1 ' and be provided with above-mentioned positioner.Because this bender has the corresponding technique effect of above-mentioned positioner, repeat no more.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
