Description
Technical field
The present invention relates to technical field of mold, is specifically a kind of diel for the punching press screw.
Background technology
The diel of traditional punching press screw comprises a bed die and a mold, it is lower mode cavity that the upper surface of bed die is provided with the blind hole identical with the screw rod shape, the lower surface of mold is provided with the cylinder pit, the top, hole of pit is provided with six prism projections, cavity between cylinder pit and six prism projections forms the upper cavity identical with the nose shape of soket head cap screw, and the center line of upper and lower two die cavitys overlaps.Bed die is fixed, and a pole is put into to lower mode cavity, pole length is greater than the height of lower mode cavity, and mold and low punch are fixed, and drives low punch to make two mould matched moulds, just pole can be struck out to a soket head cap screw.
There is following defect in the diel of prior art: screw of every punch forming, need to carry out separately die sinking, charging, punching press matched moulds, die sinking again, demoulding five steps, need how many screws of punching press just need to repeatedly operate how many times, speed is slow, efficiency is low, can't continuous punch forming; Secondly, during due to blowing, pole is put between mold and bed die, like this, before blowing, during die sinking, if the die sinking amplitude is too small, between two moulds, not, people are difficult to pole is put into distance, if but the die sinking amplitude is too large, in the time of can strengthening die sinking, matched moulds, the stroke of low punch, expend the more time, further lowers efficiency, and, there is certain risk in blowing between two moulds, just in case low punch starts accidentally, may injure staff by a crashing object; Moreover, because bed die is opening up, knockout course is too inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of and makes that punching course speed is fast, efficiency is high, safe, diel easily.
Technical solution of the present invention is, a kind of diel with following structure is provided, it comprises cylinder formwork and low punch, the upper surface of upper cylinder formwork is provided with feed well, the feed well bottom land of upper cylinder formwork is provided with the blanking channel of cylinder formwork in vertical perforation, the lower surface of upper cylinder formwork is provided with the first cylindrical pit, in the first cylindrical pit, rotatably is combined with rotating disk, upper cylinder formwork be provided with for rotate rotating disk by motor-operated transfer, the lower surface of rotating disk is concordant with the lower surface of upper cylinder formwork, rotating disk is provided with and a plurality ofly vertically runs through rotating disk and be evenly distributed on the round tube hole on same circle, upper cylinder formwork is provided with the lead of cylinder formwork lower surface at least two protrusions, the low punch sliding fit is on lead, the low punch upper surface is provided with the second cylindrical pit, be provided with six prism projections at the bottom of the hole of the second cylindrical pit, also be provided with the discharge opening that vertically runs through low punch on low punch, blanking channel is communicated with a round tube hole bottom, and the second cylindrical pit and another round tube hole over against, discharge opening and another round tube hole again over against, upper cylinder formwork is provided with for stamping forming screw being headed into to the bead that ejects of discharge opening.
The operation principle of this diel is, a pole is vertically inserted to blanking channel, pole falls under gravity in the round tube hole be communicated with blanking channel, the lower end of pole is stretched out blanking channel and is resisted against the low punch upper surface, utilize transfer to rotate rotating disk, make with the rotation of the round tube hole of pole to the second cylindrical pit with low punch over against position, now, the upper end of this round tube hole no longer is communicated with blanking channel, therefore form the cylinder blind hole of upper end closed, with the identical die cavity of the threaded shank shape of screw, and be the die cavity identical with the soket head cap screw head with the second cylindrical pit of six prisms, low punch is driven by the cylinder equal power device, making low punch and upper cylinder formwork push against is matched moulds, by the pole punch forming, it is soket head cap screw, again rotate rotating disk, make with the discharge opening of the round tube hole of screw and low punch over against, under the effect that ejects bead, screw heads into discharge opening from round tube hole, and from discharge opening, drops out under Action of Gravity Field, completes the demoulding.And the every rotation of rotating disk once, just in blanking channel, be reentered into a pole, like this, this mould can be simultaneously to the different operating step co-operating of different poles, be the every rotation of rotating disk once, can, by the stamping forming screw ejection device of putting at first, the pole of putting into after a while can be struck out to screw again, the pole that can also make finally to put into falls into a round tube hole of rotating disk, realizes a plurality of screw continuous punch formings.
After adopting above structure, diel of the present invention compared with prior art, has the following advantages:
This diel has realized the co-operating of the different operating step of different poles, can be continual by a plurality of screw punch formings continuously, avoid screw of the every moulding of prior art to carry out separately five steps, increased substantially operating efficiency, accelerated drawing velocity; Reinforced process is convenient and swift; And, due to without from reinforced between formwork and drift, therefore rationally control, make the die sinking amplitude as far as possible little, neither can cause blowing, feeding inconvenience, shorten again the stroke of drift, further pick up speed, also stop the potential safety hazard that low punch injures staff by a crashing object; Moreover knockout course adopts and ejects bead by the screw automatic ejection, without increasing power source as cylinder, the demoulding of air pump nozzle, save energy consumption fully, convenient reliable.
As improvement, comprise a universal driving shaft and travelling gear for what rotate rotating disk by motor-operated transfer, upper cylinder formwork be provided with the first cylindrical pit, be communicated with for accommodating universal driving shaft cylindrical cavity, lower end and the rotating disk of universal driving shaft are fixed, and the upper end of universal driving shaft is stretched out upper end and the travelling gear of cylindrical cavity and universal driving shaft and fixed, like this, motor drives universal driving shaft through travelling gear, and then realize dial rotation, this is simple in structure, convenient and reliable assembly.
