Abstract
The utility model relates to a kind of underframe supporting plate drift, belongs to the technical field of punch process.This drift comprises and is arranged on hanging platform on drift body and hanging platform protective, and be provided with hanging platform turning therebetween, the root of hanging platform is provided with the hanging platform chamfering of 45 degree.Change hanging platform turning into by hanging platform root wedge angle, the stress and the hanging platform rear part edge that decrease concentrated local are again stressed, solve the problem that stress is concentrated.Add hanging platform chamfering at hanging platform root, make the main stress point in the rear portion of drift be exactly part corresponding to cutting edge, avoid the active force of unbalance loading to hanging platform.This drift difficulty of processing is low, and grinding is easy, and makes extend tens times the service life of drift.
Description
Technical field
The utility model relates to a kind of underframe supporting plate drift, belongs to the technical field of punch process.
Technical background
Underframe supporting plate drift appearance and size smaller cutting edge place size is 8*4, and the softer material hardness of drift that needs of the material of underframe supporting plate is higher, is HRC64-67 now, so in use often occurs the situation that hanging platform ruptures.Because the Yield compari@of this product is high, if drift fracture can cause shut down more than half a day, losing larger, determining to transform the structure of drift, to reach the requirement extending drift service life to address this problem us.
Summary of the invention
For solving problems of the prior art, the utility model provides a kind of underframe supporting plate drift, adds hanging platform chamfering and hanging platform turning, stressed and reduce concentrated stress to reduce hanging platform rear part edge.
The technical solution of the utility model is: a kind of underframe supporting plate drift, comprises drift body and the cutting edge being arranged on drift body end.Described drift body is provided with hanging platform and is arranged on the hanging platform protective below hanging platform, and be provided with hanging platform chamfering between hanging platform and hanging platform protective, the root of described hanging platform is provided with the hanging platform chamfering of 45 degree.
The beneficial effects of the utility model are: this drift comprises and is arranged on hanging platform on drift body and hanging platform protective, and be provided with hanging platform turning therebetween, the root of hanging platform is provided with the hanging platform chamfering of 45 degree.Change hanging platform turning into by hanging platform wedge angle, the stress and the hanging platform rear part edge that decrease concentrated local are again stressed, solve the problem that stress is concentrated.Add hanging platform chamfering at hanging platform root, make the main stress point in the rear portion of drift be exactly part corresponding to cutting edge, avoid the active force of unbalance loading to hanging platform.This drift difficulty of processing is low, and grinding is easy, and makes extend tens times the service life of drift.

Fig. 1 is a kind of structure chart of underframe supporting plate drift.
Fig. 2 is the enlarged drawing of A in Fig. 1.
In figure: 1, hanging platform, 2, hanging platform protective, 3, drift body, 4, cutting edge, 5, hanging platform chamfering, 6, hanging platform turning.
Detailed description of the invention
Fig. 1 and Fig. 2 shows a kind of underframe supporting plate drift; it comprises drift body 3; the end of drift body 3 is cutting edge 4; the hanging platform protective 2 drift body 3 being also provided with hanging platform 1 and being arranged on below hanging platform 1; they are provided with a hanging platform turning 6 therebetween, and hanging platform 1 root is provided with the hanging platform chamfering 5 of 45 degree.Hanging platform turning 6 decrease concentrate the stress of local again and the rear part edge of hanging platform 5 stressed, solve the problem that stress is concentrated.Hanging platform chamfering 5 makes the main stress point in the rear portion of drift be exactly part corresponding to cutting edge, avoids the active force of unbalance loading to hanging platform 1.
