Progressive die (being also the progressive die) is made up of multiple station, each station has associated different processing in order, a series of different punch process is completed in the one stroke of punch press, after one stroke completes, material is moved forward according to a fixing step pitch by punch press feeder, multiple operation can be completed like this on secondary mould, generally there is punching, blanking, bending, trimming, the operations such as stretching, there is handling safety, be easy to automation, high velocity ram machine can be adopted to produce, reduce punch press and site area and reduce half-finished transport and warehouse takies, productivity ratio high.See Fig. 1: due to the shape of workpiece 10 and the difference of installation position, punching position on workpiece 10 have at upper surface 11, the side surface 12 of some punching positions 14 after bending, and the direction of motion of the drift 13 that the direction of motion of drift 13 on punch press or punch press drive is generally above-below direction (shown in the arrow in figure), punching 14 on the drift 13 punched workpiece side surface of such above-below direction, through hole 14 inner surface 15 of punching on workpiece side surface 12 can be made not to be perpendicular to workpiece side surface 12, but there is certain included angle A, do not meet the designing requirement to the through hole on workpiece, simultaneously, also can to workpiece side surface 12 produce lateral stresses concentrate and side force accelerate drift distortion damage.
Summary of the invention
The punching press body that the purpose of this utility model is to provide a kind of punch press with moving up and down can make the large span wedge penetration type punch structure of the progressive die of the through hole perpendicular to workpiece inclined plane in workpiece inclined plane upper punch.
The purpose of this utility model is achieved in that
The large span wedge penetration type punch structure of progressive die, comprise patrix, counterdie and punch press, the side of the lower die of described counterdie is provided with inclined plane, inclined plane is provided with more than one punching concave die perpendicular to inclined plane, counterdie outside inclined plane is provided with wedge drive block, the slip plane of wedge drive block is perpendicular to inclined plane, patrix is provided with sliding shoe, the punching press body of punch press is positioned at the upside of patrix, the drift of the side punching arranged on the downside of sliding shoe is with described punching concave die corresponding perpendicular to inclined plane, the inclined-plane that the side of sliding shoe is arranged can slide along the slip plane on wedge drive block, moving downward of punching press body can drive sliding shoe to move along the slip plane on wedge drive block to the direction perpendicular to inclined plane.
The slip plane of above-mentioned wedge drive block and the angle of horizontal plane are 45-85 to spend.
The slip plane of above-mentioned wedge drive block and the angle of horizontal plane are 70 degree.
The downside of above-mentioned lower die is provided with the chip-removal hole be communicated with described punching concave die.
The concrete structure that above-mentioned sliding shoe can slide along the slip plane on wedge drive block is: the inclined-plane on wedge drive block is provided with slideway, described sliding shoe is provided with the slide rail that can slide on slideway.
The utility model gives prominence to compared to existing technology and useful technique effect is:
1, the utility model utilizes the principle that drift briquetting can slide on the slip plane of guiding wedge surface thereof, by the banking motion changing over and drive drift briquetting that moves up and down of the punching press body of punch press, and the banking motion of drift briquetting is just in time moving both vertically relative to patrix inclined plane, and then the punching press body achieving the punch press moved up and down can make through hole perpendicular to workpiece inclined plane in workpiece inclined plane upper punch, and the through hole that punching is gone out meets the designing requirement to through hole on workpiece completely.
2, the utility model is perpendicular to the punching of workpiece inclined plane, can not produce lateral stress to drift, and the distortion being conducive to drift damages.
3, the utility model is applicable to progressive die makes through hole penetration type punch structure perpendicular to workpiece inclined plane with same punch press in workpiece inclined plane upper punch.
