Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 4 and Figure 5, a kind of positioner comprises mount pad 11, material-pressing rack 13 and power source.Material-pressing rack 13 is slidably mounted on the end face of mount pad 11, and power source is connected with material-pressing rack 13, promotes this material-pressing rack 13 and slides on the end face of mount pad 11.This material-pressing rack 13 is provided with binder surface 131, power source promotes material-pressing rack 13 and binder surface 131 is moved towards the profile on mould blank holder, plate compresses with the positive on mould blank holder by binder surface 131, thus blank can be eliminated in punching production process and bend sagging impact, have effectively achieved the precise positioning of blank, and then improve the quality of stamping parts.Preferably, power source is cylinder 12, and this cylinder 12 is packed in by bolt on the end face of mount pad 11, and in cylinder 12, the free end of piston rod is fixedly connected with material-pressing rack 13.Cylinder 12 structure is simple, is convenient to install, and in addition, power source is optional motor or other components and parts also.
A kind of embodiment, as shown in Figure 4 and Figure 5, material-pressing rack 13 comprises the first bar 13a and the second bar 13b, one end of first bar 13a and one end of the second bar 13b intersect vertically, the other end of the first bar 13a and the end face of mount pad 11 are fitted, the end face of the other end of the second bar 13b is binder surface 131, the middle part of the first bar 13a is fixedly connected with the free end of piston rod in cylinder 12, preferably, bolt 15 is through the free end thread connection of piston rod in the middle part of the first bar 13a and cylinder 12, this connecting mode was both convenient to dismounting, was convenient to again regulate.The material-pressing rack 13 of said structure is in L-type, and structure is simple and materials are less, is convenient to processing and manufacturing.In order to ensure slip stationarity and the accuracy of material-pressing rack 13, preferably, the both sides of one end that the end face of the first bar 13a and mount pad 11 is fitted are provided with flange platform 132, and the bearing of trend of this flange platform 132 is vertical with the second bar 13b; The end face of mount pad 11 is fixed with the guide pad 14 coordinated with flange platform 132 slide guide, guide pad 14 is fixed by screws in the end face of mount pad 11, coordinates with flange platform 132 effect material-pressing rack 13 being played to slide guide, guiding.In order to reduce the wearing and tearing between sliding part, preferably, the outer surface that end face, the outer surface of flange platform 132 and the guide pad 14 that fit of the end face of the first bar 13a and mount pad 11 and flange platform 132 fit is provided with wearing layer.Preferably, wearing layer is the wearing layer formed by kollag, and kollag bearing capacity is strong, boundary lubrication is excellent.In addition, wearing layer also can select the wearing layer that graphite is formed.
Be applied as example below with Luggage Hold Cover inner panel punching press drawing die, boot-lid inner panel moulding is roughly down " V " font, common locate mode cannot realize drawing die blank stable, accurately locate.
As shown in Figure 6, this drawing die mainly comprises positioner 1, retainer positioner 2, patrix, punch 4, blank holder 5, die shoe 6, blank 7.Positioner 1, retainer positioner 2 are fixedly mounted on blank holder 5 respectively.
Specific works process is as follows: as shown in Figure 7, and before press work, lathe push rod is by blank holder 5 jack-up, and now the upper profile peak of blank holder 5 is higher than the profile peak on punch 4; Cylinder 12 in binder positioner 1 is for shrinking rollback state.Mould put into by blank, blank two ends hold up by the retainer block on retainer positioner 2, zone line is supported by the profile peak on blank holder 5, this kind of locate mode front blank that makes to be shaped is in level, meanwhile, confined planes in retainer positioner 2 on limiting plate pedestal carries out the location of blank horizontal direction, and both combinations can realize the accurate location of blank.
Along with press setting in motion, patrix moves downward, simultaneously, cylinder 12 is extended by gas circuit control push rod and is promoted material-pressing rack 13 and travels forward, binder surface 131 on material-pressing rack 13 and the positive on blank holder 5 are by blank holding, prevent the lower profile in die two ends from first contacting blank, collect together before causing blank to be shaped.
Along with patrix continues to move downward, the lower profile in die two ends is pressed in the both ends of blank and impels the retainer block on retainer positioner 2 to rotate, the retainer portion on retainer block is crossed at blank two ends, and patrix 3 continues to move downward until compressed blank border with blank holder 5 is closed.Subsequently, patrix 3 and blank holder 5 move downward jointly, and blank starts contact with punch and is shaped until mould is closed.After drawing completes, separately, cylinder 12 shrinks and pulls material-pressing rack 13 rollback upper and lower mould.
In sum, content of the present utility model is not limited in the above-described embodiments, and those skilled in the art can propose other embodiment easily according to guiding theory of the present utility model, and these embodiments are all included within scope of the present utility model.
