Technical Field
The invention relates to the technical field of stamping dies, in particular to an adjustable punching device for an arc-shaped workpiece.
Background
Hydraulic combined punching and shearing machines generally have five stations: the standard configuration punching station, angle steel shearing station, bar shearing station, panel shearing station, corner cut station etc. can realize processing multiple shaped steel and panel, reach the effect of a tractor serves several purposes, are modern machine-building industry like: ideal equipment for metallurgy, bridge, communication and electric power industries, so that it is more widely used in production practice
And the punching die is used for punching the workpiece through the punching die in the punching station. The existing punching die comprises a fixed die holder, a punch, a guide die holder and a female die. When the punching die works, the fixed die holder moves downwards to drive the punch to punch a workpiece placed on the upper surface of the female die, so that punching is finished. However, the adjustable range of the existing punching die of the existing punching and shearing machine of the existing punching die is limited, and only specific plates, such as plates below 330 × 20 or 480 × 10, can be punched or special-shaped workpieces with small arc degrees can be processed, and the special-shaped workpieces such as arc-shaped workpieces cannot be processed, so that the processing self-made working range is greatly restricted, and the labor intensity is increased.
Disclosure of Invention
The invention aims to provide an adjustable punching die which is wider in processing range and applicable to arc-shaped plates.
The technical scheme of the application is as follows:
the utility model provides a punching device with adjustable be used for arc work piece, includes frame, base platform and die punch holder, be provided with die punch holder and hydraulic pressure material pole in the frame, the bottom that the material pole was pressed to hydraulic pressure is equipped with the mould drift, be provided with the fixed block on the base platform, the draw-in groove has been seted up at the fixed block middle part, the lower mould of punching a hole has been placed in the draw-in groove, a serial communication port, the die punch holder includes fixed die holder and direction die holder, fixed die holder and frame fixed connection, fixed die holder below is through adjusting the stand and connecting the direction die holder, it is two sets of to adjust the stand, and two sets of regulation stands all include threaded rod, lower threaded rod and bolt cover, the bolt cover is equipped with screwed hollow structure for the inner wall, the screw.
Further, fixed die holder is the arc, be equipped with frame fixed orifices and last threaded rod connecting hole on the fixed die holder, the frame fixed orifices that institute includes annular fixed orifices and opening fixed orifices, the direction die holder is the rectangle, the direction die holder is equipped with the guiding hole and the threaded rod connecting hole down that can supply the mould drift to pass.
Furthermore, the bolt sleeve is provided with a fixing hole, and the fixing hole is provided with a fixing nut.
Furthermore, the punching lower die is a hollow cylinder.
The beneficial effect of this application does:
the adjustable distance range between the dies is enlarged, so that the dies can be adjusted according to the size change of a machined part, and the original plate processing is expanded to the punching processing of the section bar; the processing mode is also punched a hole by original individual layer piece, changes the processing of punching a hole simultaneously of present multilayer, has not only promoted work efficiency, has saved the manpower, also makes the pitch of holes of processing more accurate simultaneously.
