Abstract
The utility model discloses a planet wheel expansion hole machining punch. The planet wheel expansion hole machining punch comprises a punch body, a blunt cutting edge is arranged at the front end of the punch body, the side face of the blunt cutting edge is an inclined face, and the side face of the blunt cutting edge inclines from the position connected with the punch body to the inner side. According to the planet wheel expansion hole machining punch, the inclined blunt cutting edge is arranged at the punching end of the punch, a dead angle of an expansion hole of a planet wheel is machined by adjusting the angle of inclination in the machining process. The planet wheel expansion hole machining punch is simple in structure and easy to popularize.
Description
Technical field
The utility model relates to a kind of stamping tool, and concrete is the swollen hole processing of a kind of planetary gear drift.
Background technology
At present, drift used when the swollen hole of planetary gear is die-cut, and the inwall of the forming hole of formation has processing capacity more than also, allowance needs secondary operations, pass through secondary operations simultaneously, need to use rough turn and finish turning, cause the material of this allowance position to slattern, therefore being necessary to design a kind of novel drift not only can save material, improve the quality of products, but also without secondary operations, reduce process time, enhance productivity, meet the demand of plant produced.
Utility model content
The utility model proposes the swollen hole processing of a kind of planetary gear drift, reduced process time, improved production efficiency.
The technical solution of the utility model is achieved in that the swollen hole processing of a kind of planetary gear drift, comprise punch body, described punch body front end arranges blunt cutting edge, and described blunt cutting edge side is inclined-plane, and described blunt cutting edge side tilts to the inside by connecting punch body place.
Further, the gradient on described inclined-plane be 0 ° 30 '.
Further, described blunt edge surface is provided with enhancement Layer.
Further, described hardness enhancement Layer is quench hardened case.
Further, described hardness enhancement Layer is that DLC is filmed.
The beneficial effects of the utility model are: planetary gear of the present utility model is swollen hole processing drift arranges the dull edge of inclination by the punching press end at drift, process the dead angle in the swollen hole of planetary gear man-hour adding by adjusting angle of inclination.The utility model is simple in structure, is easy to promote.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the enlarged drawing of the upward view of the utility model embodiment.
In figure: 1, punch body; 2, blunt cutting edge; 3, hardness enhancement Layer.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The swollen hole processing of a kind of planetary gear drift as shown in Figure 1, Figure 2 and Figure 3, comprise punch body 1, described punch body 1 front end arranges blunt cutting edge 2, and described blunt cutting edge 2 sides are inclined-plane, described blunt cutting edge 2 sides tilt to the inside by connecting punch body 1 place, the gradient on described inclined-plane be 0 ° 30 '.
As preferably, described blunt cutting edge 2 surfaces are provided with hardness enhancement Layer 3.
As preferably, described hardness enhancement Layer 3 is quench hardened case.
As preferably, described hardness enhancement Layer 3 is filmed for DLC.
Planetary gear of the present utility model is swollen, and hole processing drift arranges the dull edge of inclination by the punching press end at drift, by adjusting angle of inclination, process the dead angle in the swollen hole of planetary gear man-hour adding, punching press shaping is carried out in swollen hole, make material can all be depressed into swollen hole wall, be that the inwall processing of swollen hole is even, when not only increasing planetary gear density, also reduced the consumption of material.
The utility model is simple in structure, is easy to promote.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
