Abstract
The utility model relates to a die shank capable of rapidly replacing a punching head, which comprises a die shank, screw plugs, press plates, screws, safety pins, safety pin pressing sheets, bucking bars and springs. The bottom of the die shank is provided with a punching head mounting hole for mounting the punching head. Two symmetrical bucking bar mounting holes are arranged in the upper part of the excircle of the die shank, the bucking bar mounting holes are inclined holes, one ends of the bucking bar mounting holes are communicated with the punching head mounting hole, and the other ends of the bucking bar mounting holes are provided with inner threads. Two symmetrical safety mounting holes are arranged in the lower part of the excircle of the die shank, one ends of the safety mounting holes are communicated with the bucking bar mounting holes, and the axes of the safety pin mounting holes are perpendicular to the axes of the bucking bar mounting holes. The bucking bars and the springs are arranged in the bucking bar mounting holes of the die shank, the screw plugs are arranged in the thread holes of the bucking bar mounting holes. The safety pins and the safety pin pressing sheets are arranged in the safety pin mounting holes of the die shank, part of the front ends of the safety pins are embedded in the bucking bar mounting holes, to prevent the bucking bars from drawing back when the die works. The pressing plates are pressed on the safety pin mounting holes, and are fixed on the excircle of the die shank through the screws.
Description
Technical field
The utility model relates to the cold stamping processing mold in the field of machining, the especially a kind of die shank that can change drift fast.
Background technology
The drift of used cold punching die generally all is installed on the die shank, adopts close-fitting to be pressed into during installation usually, with screw drift is fixed then; Or the employing interference fits, drift is fixed with screw at the die shank periphery then.All there is the problem of loading and unloading trouble in these two kinds of methods, when the loading and unloading drift, waste time and energy, and operation is also inconvenient.In addition, adopt fixedly drift of screw, die shank causes thread damage easily in the course of the work because of impact force action, has influence on the operate as normal of mould.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art and die shank that a kind of quick replacing drift is provided.
The technical scheme of the utility model is: a kind of die shank of quick replacing drift, form by die shank, screw plug, pressing plate, screw, latch, latch compressing tablet, top rod and spring.
The bottom of die shank is provided with the drift installing hole of an installation drift.Be provided with the top rod installing hole of two symmetries on the top of die shank cylindrical, pushing up excellent installing hole is inclined hole, and an end communicates with the drift installing hole, and the other end is processed with internal thread.Be provided with the latch installing hole of two symmetries in the bottom of die shank cylindrical, latch installing hole one end communicates with the excellent installing hole in top, the axis of latch installing hole and the axis normal of pushing up excellent installing hole.
Top rod and spring are installed in the top rod installing hole on the die shank, and screw plug is installed in the screwed hole of the excellent installing hole in top.Latch and latch compressing tablet are installed in the latch installing hole on the die shank, and some inserts the latch front end in the excellent installing hole in top, and its effect is when mold work, to prevent to push up rod to retreat.Pressing plate is pressed on the latch installing hole, and is fixed on the cylindrical of die shank through screw.
The utility model compared with prior art has following characteristics:
The die shank of the quick replacing drift that the utility model provides is simple in structure, the replacing drift is convenient and swift, locking is solid and reliable, wide accommodation.
Further describe below in conjunction with accompanying drawing and the specific embodiment detailed structure the utility model.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the vertical view in the accompanying drawing 1.
The specific embodiment
A kind of die shank of quick replacing drift is made up of die shank 1, screw plug 2, pressing plate 3, screw 4, latch 5, latch compressing tablet 6, top rod 7 and spring 8.
The bottom of die shank 1 is provided with the drift installing hole 1-3 of an installation drift 9.Be provided with the top rod installing hole 1-1 of two symmetries on the top of die shank 1 cylindrical, pushing up excellent installing hole 1-1 is inclined hole, and an end communicates with drift installing hole 1-3, and the other end is processed with internal thread.Be provided with the latch installing hole 1-2 of two symmetries in the bottom of die shank 1 cylindrical, latch installing hole 1-2 one end communicates with the excellent installing hole 1-1 in top, the axis of latch installing hole 1-2 and the axis normal of pushing up excellent installing hole 1-1.
Top rod 7 is installed in the top rod installing hole 1-1 on the die shank 1 with spring 8, and screw plug 2 is installed in the screwed hole of the excellent installing hole 1-1 in top.Latch 5 is installed in the latch installing hole 1-2 on the die shank 1 with latch compressing tablet 6, and some inserts latch 5 front ends in the excellent installing hole 1-1 in top, and its effect is when mold work, to prevent to push up rod 7 to retreat.Pressing plate 3 is pressed on the latch installing hole 1-2, and is fixed on the cylindrical of die shank 1 through screw 4.
During use, unclamp the screw 4 on 1 liang of side guide 3 of die shank earlier, two screws below taking out; Pressing plate 3 is turned over an angle to the side; Crush board 3 leaves the end face of latch installing hole 1-2, and latch 5 is automatically deviate from from latch installing hole 1-2 with latch compressing tablet 6 like this, firmly spurs drift 9 this moment downwards; Top rod 7 promotes spring 8 compressions, deviates from the drift installing hole 1-3 of drift 9 from die shank 1.During installation; Drift 9 is firmly upwards promoted, make two inverted cone surfaces on drift 9 tops be in the position that the excellent 7 lower end semicircle cambered surfaces in top belong to, top rod 7 stretches between two inverted cone surfaces of drift 9 heads under the elastic force effect of compression spring 8 like this; Thereby with drift 9 lockings; Respectively latch of both sides 5 and latch compressing tablet 6 are packed in the latch installing hole 1-2 then, pressing plate 3 is turned on the latch installing hole 1-2, install and tighten screw 4.
