Description
Technical field
The utility model relates to a kind of mould, particularly a kind of processing mold assembly of slotted nut.
Background technology
As shown in Figure 1, 2, slotted nut 4 includes nut body 41, and nut body 41 is provided with internal thread hole 42, also evenly offers some grooves 43 on nut body 41 upper surfaces.Slotted nut generally all tie tail offer foraminate bolt and use together, in the groove with split pin inserting bolt afterbody aperture and nut, and the split pin afterbody broken into two with one's hands with the nut side be adjacent to.
At present, existing processing for slotted nut has generally comprised following step: (1) directly extrudes nut body by mold hot; (2) accurate machining internal thread hole; (3) groove milling utilizes milling cutter to mill out some grooves on the nut upper surface; (4) heat treatment; (5) tapping processes internal thread hole; (6) electroplate, increase surface strength, wearability.
But this processing method needs processing nut body earlier, groove milling again, thus make that production efficiency is low, labor strength is big; And the groove bottom land that mills out is wedge angle, so easy wearing and tearing split pin, even cause the split pin fracture and cause potential safety hazard.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of processing mold assembly of slotted nut, by with nut body and the groove time processing moulding that is arranged on the nut body upper surface, thereby improved production efficiency, reduced working strength of workers.
The technical solution of the utility model: a kind of processing mold assembly of slotted nut, include nut body, groove mould and internal thread hole mould, described nut body, the groove mould includes drift A, push rod A and die ontology A, described die ontology A is provided with the nut body forming cavity, described nut body forming cavity two ends extend to respectively die ontology A on, the lower surface, described drift A, push rod A lays respectively at the top of die ontology A, the below, described push rod A, drift A all cooperates with the slippage of nut body forming cavity, described drift A lower surface is provided with some groove moulding projectioies and the half-formed bar of internal thread hole portion, described push rod A upper surface and described die ontology A lower surface are positioned at same plane, be provided with the gap between described nut body forming cavity and described push rod A are circumferential, described internal thread hole mould includes drift B, push rod B and die ontology B, described die ontology B is provided with the nut body containing cavity that is complementary with described nut body forming cavity, described push rod B, drift B all cooperates with the slippage of nut body containing cavity, described drift B is provided with internal thread hole curved lever portion, and described push rod B is provided with through hole.
Adopt technique scheme, utilize nut body, groove mould to stamp out the groove and the part internal thread hole of nut body, nut body upper surface, utilize the internal thread hole mould to stamp out internal thread hole again, be provided with the gap between described nut body forming cavity and described push rod A are circumferential, can make things convenient for metal to flow out die ontology like this between the gap, thereby reduced the suffered compression of die ontology A, prolonged the service life of die ontology; Internal thread hole mould push rod B goes up the through hole that is provided with and flows out for waste material.
Further setting of the present utility model: described groove moulding projection lower surface is reclinate arc surface.
Adopt above-mentioned further setting, the circular arc lower surface of described groove moulding projection can be so that the bottom portion of groove of the nut body upper surface that processes be an arc surface, increased the contact area of groove and split pin like this, improved stiction, make that split pin is not easy to damage, eliminated potential safety hazard.
