Description
Technical field
The utility model relates to a kind of device of gear blank forming, relates in particular to a kind of device to the punching simultaneously of gear blank and trimming.
Background technology
The Gear Processing moulding need to be passed through trimming operation and punching operation, existing processing unit (plant) can not carry out trimming and the punching of gear simultaneously, only have after formerly completing the trimming operation and carry out again the punching operation, or first complete trimming again after the punching operation, working (machining) efficiency is lower, therefore is necessary to provide a kind of gear machining equipment that can realize that edge-cutting and hole-punching carries out simultaneously.
The utility model content
The technical problem that the utility model solves is: a kind of device to the punching simultaneously of gear blank and trimming is provided.
The technical solution of the utility model is: a kind of device to the punching simultaneously of gear blank and trimming, comprise drift location-plate, drift and punching concave die, described drift is fixed on the lower surface of described drift location-plate, it is characterized in that, the lower surface of described drift location-plate also is fixed with the backing plate with center hole, and described drift gap is through the center hole of described backing plate; The lower surface of described backing plate is provided with edger, this edger comprises cylindrical cavity and lower cylindrical cavity, the internal diameter of upper cylindrical cavity is greater than the internal diameter of lower cylindrical cavity, the junction of upper cylindrical cavity and lower cylindrical cavity forms spacing seam, the end face of described upper cylindrical cavity and described backing plate are fixed, the lower port of described lower cylindrical cavity is along the circular knife edge that forms described edger, described drift successively gap through upper cylindrical cavity, the lower cylindrical cavity of described edger.
Described edger is arranged with compacting ring outward, and this compacting ring and described drift location-plate are fixed.
On described drift, gap is arranged with Compress Spring and columnar stripper, and the upper end of described stripper is provided with the limiting stand matched with described spacing seam, and Compress Spring is between described backing plate and described limiting stand; When Compress Spring is shifted stripper onto spacing position downwards, the lower cylindrical cavity of described edger is stretched out in the lower surface of stripper.
Described punching concave die also is provided with the counterdie compacting ring outward.
The beneficial effects of the utility model are: during the utility model work, the drift location-plate is connected to forcing press, the gear blank is put into to punching concave die, starting pressure machine back punching head location-plate drives edger and moves down, edger excision gear blank overlap, drift continues down to move and to go out gear blank hole, so the utility model can complete punching and trimming to the gear blank simultaneously, has improved the operating efficiency of Gear Processing.
After the utility model punching and trimming machine, forcing press moves upward and returns, the gear blank under the effect of Compress Spring, promote stripper the gear blank from the drift loading and unloading material, complete a working cycles.Therefore the utility model can also automatic discharging, has further improved the operating efficiency of Gear Processing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Referring to Fig. 1, a kind of device to the punching simultaneously of gear blank and trimming, comprise drift location-plate 1, drift 2 and punching concave die 3, drift 2 is fixed on the lower surface of drift location-plate 1, the lower surface of drift location-plate 1 also is fixed with the backing plate 4 with center hole, and drift 2 gaps are through the center hole of backing plate 4; The lower surface of backing plate 4 is provided with edger 5, wherein edger 5 is fixedly connected with backing plate 4 by straight pin 10, interior hexagonal cylindrical screw 11, this edger 5 comprises cylindrical cavity and lower cylindrical cavity, the internal diameter of upper cylindrical cavity is greater than the internal diameter of lower cylindrical cavity, the junction of upper cylindrical cavity and lower cylindrical cavity forms spacing seam, the end face of upper cylindrical cavity and backing plate 4 are fixing, the lower port of lower cylindrical cavity is along the circular knife edge that forms edger 5, drift 2 successively gap through upper cylindrical cavity, the lower cylindrical cavity of edger 5.The outer compacting ring 6 that is arranged with of edger 5, this compacting ring 6 is fixing with drift location-plate 1.On drift 2, gap is arranged with Compress Spring 7 and columnar stripper 8, and the upper end of stripper 8 is provided with the limiting stand matched with spacing seam, and Compress Spring 7 is between backing plate 4 and limiting stand; When Compress Spring 7 is shifted stripper 8 onto spacing position downwards, the lower cylindrical cavity of edger 5 is stretched out in the lower surface of stripper 8.The outer counterdie compacting ring 9 that also is provided with of punching concave die 3.
The utility model is assembling like this: in the middle of the edger 5 of at first stripper 8 being packed into, the edger 5 of again Compress Spring 7 being packed into, again edger 5 is fixedly connected with backing plate 4 by straight pin 10, interior hexagonal cylindrical screw 11, reinstall drift 2, with compacting ring 6, be fixed on drift location-plate 1, the drift location-plate is connected with the forcing press tup.Punching concave die 3 use counterdie compacting rings 9 are connected with the equipment lower table.
During the utility model work, the drift location-plate is connected to the forcing press tup, gear blank 12 is put into to punching concave die 3, starting pressure machine back punching head location-plate 1 drives edger 5 and moves down, the overlap of edger 5 excision gear blanks 12, and drift 2 continues down move and go out gear blank hole, after punching and trimming machine, forcing press moves upward and returns, the gear blank under the effect of Compress Spring 7, promote stripper the gear blank from the drift loading and unloading material, complete a working cycles.
