Abstract
The utility model provides a sidestep type gear amplitude plate punch. The edge of the punch consists of a front edge, an inclined edge and a rear edge, wherein the front edge is connected with the rear edge by the inclined edge and is shaped as a sidestep. The sidestep type gear amplitude plate punch can be subject to the force in a form of sidestep when being punched, so that the action force of the punch on the gear amplitude plate can be reduced, thus reducing the deformation quantity of gear die forgings.
Description
Technical field
The utility model relates to a kind of forging part punching die, especially a kind of gear former drift of step.
Background technology
The general used large gear of diesel engine gearbox, for loss of weight, 3～6 holes of communications centre all on the former.The drift cutting edge of traditional gear former punching die at grade, cutting edge is simultaneously stressed during punching; Gear die forging tip edge is thick, and former is thin, and the punching backgear is yielding.Cutting edge rust after the former drift uses more than 500 time, the distortion of punching backgear does not reach the deformation technology requirement.For guaranteeing that gear shifting quadrant texturing in forging part specification requirement scope, needs frequent change former drift, cause production efficiency low, cost is high.
Summary of the invention
The purpose of the utility model provides a kind of gear former drift of step, can eliminate or reduce punching to the distortion that the gear die forging causes, enhances productivity, and reduces cost.
In order to solve the problems of the technologies described above; The technical scheme of the utility model is following: a kind of gear former drift of step; It is characterized in that: the cutting edge of said drift is made up of preceding cutting edge, declivous cutting edge, back cutting edge, and preceding cutting edge is connected stepped through declivous cutting edge with the back cutting edge.
Improvement to technique scheme: the drop L before said between cutting edge and the back cutting edge is greater than the thickness of gear former, and preceding cutting edge is 1/3～1/2 of a former punch diameter with the width of back cutting edge.
Beneficial effect:
The utility model provides a kind of gear former drift of step, can be when punching ladder stressed, reduce the active force of drift, thereby reduce the deflection of gear die forging the gear former.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 be among Fig. 1 K to sketch map.
The specific embodiment
Gear former drift like Fig. 1, a kind of step of the utility model shown in Figure 2; The cutting edge of said drift 1 is made up of preceding cutting edge 2, declivous cutting edge 3, back cutting edge 4; Preceding cutting edge 2 is connected stepped through declivous cutting edge 3 with back cutting edge 4; Drop L between preceding cutting edge 2 and the back cutting edge 4 is greater than the thickness of gear former, and preceding cutting edge 2 is 1/3 of a former punch diameter with the width a of back cutting edge 4.
Gear former ladder is stressed when punching, preceding cutting edge 2 first Contact Tooth wheel former punchings, and secondly, whole punch process is accomplished in declivous cutting edge 3 punchings, moreover back cutting edge 4 punchings.Because drift 1 cutting edge is a notch cuttype contact former, has reduced the active force of 1 pair of gear former of drift, thereby has reduced the deflection of gear die forging.
Claims (2)
1. the gear former drift of a step is characterized in that: the cutting edge of said drift is made up of preceding cutting edge, declivous cutting edge, back cutting edge, and preceding cutting edge is connected stepped through declivous cutting edge with back cutting edge.
2. the gear former drift of a kind of step according to claim 1 is characterized in that: the drop L before said between cutting edge and the back cutting edge is greater than the thickness of gear former, and preceding cutting edge is 1/3～1/2 of a former punch diameter with the width of back cutting edge.
