Abstract
The invention discloses a simple precision-stamping die. The simple precision-stamping die comprises a concave-convex die which is mounted on a supporting plate through a discharging bolt, wherein a lower cushion board is arranged below the supporting plate; a sleeve sleeves the outer edge of the lower cushion board; ethylene propylene rubber of which the outer edge is sleeved with a sealing ring is filled in the lower cushion board; a propping rod is arranged in the concave-convex die, and a concave die is arranged at the upper end of the propping rod; a convex die of which the top end is equipped with a gear ring pressing plate is arranged at one side of the concave die; a knocking-out rod, which is arranged in the convex die, is mounted on an upper cushion board through a fixing plate; a pressure regulating plate in which a connecting rod is arranged is mounted in the center of the upper end of the upper cushion board; an inclined plate is connected to the top end of the connecting rod. With the adoption of the simple precision-stamping die, a workpiece can be stamped at once, so that the material plasticity can be improved, the workpiece processing precision and working efficiency can be improved, and the damage rate of the workpiece can be reduced.
Description
Technical field
The present invention relates to machinery manufacturing technology field, be specially a kind of Simple Fine Blanking.
Background technology
Mould is manufacturing important process basis, and in China, Making mold belongs to special equipment manufacturing.Although China starts manufacture mould and use mould very early, but does not forms industry for a long time.Although die & mould industry of China quickly grows, but compared with demand, it is clear that supply falls short of demand, its main breach concentrates on accurate, large-scale, complicated, long-service die field.
Stamping-out is to utilize punch die to make a kind of stamping procedure that portion of material or process part processing separate with another part material, process part processing or waste material, stamping-out is that shearing, blanking, punching, punching lack, jet-bedding, cutting, chisel are cut, trimming, cut tongue, cut, the general name of the separation circuit such as trimming.The most commonly used stamping-out mode is that blank is placed in lower cavity die top, and punch is descending directly carries out punching press to blank, i.e. completes stamping-out after the waste material blanking that stamping-out falls.Often there are some problems in the workpiece using this most common stamping-out gained: its sheared edge has relatively rough fracture belt, and with certain gradient, but also there may be collapse angle, burr etc., the workpiece quality processed is poor.
Fine blanking die is to carry out stamping-out under the state making plate be in three dimension stress, die-cut flawless of punching and tear, the punch die of the product that dimensional accuracy is high.
The present invention provides a kind of Simple Fine Blanking, it is possible to increase the plasticity of material, it is suppressed that the generation of sheared edge crackle, can reduce and even eliminate coarse fracture belt, improves workpiece processing quality etc..
Summary of the invention
Because the drawbacks described above of prior art, the present invention provides a kind of Simple Fine Blanking.
For achieving the above object, the invention provides a kind of Simple Fine Blanking, including concave-convex mold, described concave-convex mold is arranged on supporting plate by unloading bolt, the lower section of described supporting plate is provided with lower bolster, the outer rim of described lower bolster is set with lasso, is filled with EP rubbers inside described lower bolster, and described EP rubbers outer rim is set with sealing ring；Described concave-convex mold is internally provided with push rod, and the upper end of described push rod is provided with die, and the side of described die is provided with punch, and the top of described punch is provided with gear ring pressing plate, and described punch is internally provided with makes bar, and described bar of beating is arranged on upper padding plate by fixed plate；The upper end center position of described upper padding plate is provided with regulator board, described regulator board be internally provided with extension bar, the top of described extension bar connects swash plate, the other end of described swash plate is connected with slide plate, described slide plate is connected with resetting-mechanism by oblique contract, and described resetting-mechanism is internally provided with the spring that multiple head and the tail are sequentially connected with；Described resetting-mechanism is arranged on described supporting plate by support.
Further, the top of described extension bar is provided with screw plug.
Further, it is provided with push pedal between described die and punch.
Further, it is provided with polyurethane rubber between described extension bar and swash plate.
Further, the outside of described slide plate is provided with block.
Beneficial effects of the present invention: present configuration is reasonable in design, easy to operate, disposably workpiece can be carried out stamping-out, improve the plasticity of material, it is suppressed that the generation of sheared edge crackle, can reduce and even eliminate coarse fracture belt, improve Workpiece Machining Accuracy and operating efficiency, reducing the spoilage of workpiece, finished surface is the most easy to wear, finished product life.
