Description

Detachable guide pillar blanking die
Technical field
The present invention relates to a kind of stamping and blanking mode structure, be specially a kind of detachable guide pillar blanking die.
Background technology
Blanking die is indispensable technological equipment in punching production, and good mould structure is the Reliable guarantee realizing process program.The quality of punching parts and precision height, depend primarily on quality and the precision of blanking die, whether blanking die structure is reasonable, advanced, has a direct impact to production efficiency and the service life of blanking die itself and the safety, convenience etc. of operation.Due to blanking part shape, size, precision and production lot and working condition different, the structure type of blanking die is also different.
Blanking die is a kind of blanking die of common form, in traditional blanking die use procedure, in order to ensure the gap uniformity between die and punch, the movement locus of guiding parts to punch of normal employing guide pillars and bushes composition leads, in workpiece process, guide pin bushing will move up and down along guide pillar, therefore after mould uses a period of time, guide pillar will there will be certain wearing and tearing, now as changed guide pillar not in time, the gap made between guide pillars and bushes is strengthened, guiding accuracy reduces, workpiece processing quality declines, because guide pillar in traditional blanking die and die shoe adopt interference fit, therefore needs are changed together with die shoe when needing to change guide pillar, add mold use cost.
Summary of the invention
The invention is intended to provide one can guide pillar for convenience detach, reduce the detachable guide pillar blanking die of mould use cost.
Detachable guide pillar blanking die in this programme, comprise upper mould part and lower mould part, upper mould part comprises die shank and punch, die shank is connected with external pressure machine, die shank overcoat has upper bolster, punch retainer is provided with below upper bolster, punch retainer is connected with punch, lower mould part comprises die shoe, die shoe top is provided with die, die is provided with material-dropping hole, die shoe is provided with discharge opening, also comprise guiding parts, guiding parts comprises guide pillar, guide pin bushing and lining, guide pin bushing is connected with upper bolster interference, lining is threaded with die shoe, guide pillar is divided into cylindrical end and tapering end, guide pillar cylindrical end coordinates with guide pin bushing, guide pillar tapering end coordinates with lining, guide pin bushing can move up and down along guide pillar, guide pillar tapering end is also provided with packing ring, packing ring is threaded with guide pillar.
The operation principle of the detachable guide pillar blanking die in this programme is: when needs add man-hour to workpiece, workpiece is positioned over mould, under the drive of outside forcing press, guide pin bushing moves downward along guide pillar, punch moves downward under the direction of guide pillars and bushes guides, under the acting in conjunction of punch and die, workpiece is punched into desired structure, stamping is pushed out from die shoe discharge opening through die material-dropping hole, punch backhaul, workpiece is pushed ahead, until process required hole on workpiece, guiding due to punch relies on guide pin bushing to realize along moving of guide pillar, therefore after mould uses a period of time, guide pillar will there will be certain wear phenomenon, when guide pillar changed by needs, only need dismantle the screw at lower gasket and lining place, the dismounting of guide pillar can be realized, after more finishing changing guide pillar, install the screw at packing ring and lining place, the installation of guide pillar, mold work continues.
The beneficial effect of the detachable guide pillar blanking die in this programme is: by increasing lining between guide pillar and die shoe, guide pillar and lining removably connect, lining and die shoe removably connect, and then realize removably connecting of guide pillar, thus after efficiently solving guide pillar wearing and tearing, need the problem of replacing, reduce mold use cost.
Further, also comprise spring-loaded stripping parts, spring-loaded stripping parts comprise unloading bolt, unloading bolt is divided into smooth section and thread segment, unloading bolt smooth section is successively through upper bolster and punch retainer, unloading bolt thread segment is provided with stripper, upper bolster and punch retainer can move up and down along unloading bolt smooth section, unloading bolt smooth section is also provided with discharging spring, offset on the downside of discharging spring one end and punch retainer, offset on the upside of the other end and stripper, punch and described die are before matched moulds, and punch is no more than place plane on the downside of stripper.When carrying out work pieces process, stripper moves downward under the drive of outside forcing press, due to before matched moulds, punch is no more than place plane on the downside of stripper, therefore when stripper move downward touch surface of the work time, punch not yet touches surface of the work, under the continuous action of outside forcing press, stripper position remains unchanged, upper bolster and punch retainer move downward along unloading bolt smooth section, discharging spring compresses downwards, and stripper provides a pressure-plate-force for surface of the work, makes surface of the work keep smooth.
Further, die is provided with the hook-type pin stop for feed direction Workpiece fixing, due to the hook design that hook-type pin stop is special, can make the edge of a knife of pin-and-hole away from die of this hook-type pin stop of installation, thus effectively can ensure the intensity of die, improve the service life of die.
Further, be also provided with the backing plate for disperseing punch transmission of pressure between upper bolster and punch retainer, the pressure of punch transmission can disperse by backing plate, thus prevents punch crush injury upper bolster, improves the mold use life-span.
Further, lower mould part also comprises the stock guide being positioned at die top guiding workpiece feed direction, and under the effect of stock guide, workpiece enters mould along correct direction and processes, and ensure that the crudy of workpiece.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
