Abstract

The utility model discloses an orifice chamfering or rounding die, which aims at providing the orifice chamfering or rounding die with simple structure, easy manufacturing, high processing accuracy and high efficiency. The orifice chamfering or rounding die comprises an upper die and a lower die, wherein a punch head with steps is arranged in the upper die or the lower die. The orifice chamfering or rounding die is characterized in that the shape and size of the front end of the punch head are matched with that of a hole of a work piece requiring chamfering or rounding; the step surface is larger than a chamfered or rounded orifice; the front-end side surface of the punch head is vertical to the step surface; and a connecting inclined plane or a round angle corresponding to a chamfered angle or a rounding of the orifice is arranged at the connecting position of the root part of the front end of the punch head and the step surface. When in use, the work piece is put between the upper die and the lower die, the chamfered or rounded hole is in alignment with the front end of the punch head, when the upper die and the lower die are closed after the front end of the punch head enters the hole, the chamfered angle or the rounding are formed at the orifice of the work piece due to the extrusion of the connecting inclined plane or the round angle of the root part of the front end of the punch head and the step surface. Therefore, chamfering or rounding is realized very conveniently, which is finished while punching.

Description

The mould of aperture chamfering or rounding
Technical field
The utility model relates to cold-punching mold, relates in particular to the mould of processing aperture chamfering or rounding.
Background technology
In the cold stamping processing, punching is the most frequently used operation, also need be for some stamping parts at aperture chamfering or rounding for requirement easy to assembly or that cooperate, and traditional method is through spot-facing to the drilling machine again after the punching, makes chamfering or rounding in the aperture.Such processing technology is loaded down with trivial details, and efficient is low, and precision is not easy to guarantee.
The utility model content
The purpose of this utility model provides a kind of simple in structure, easy to manufacture, the aperture chamfering that the precision of processing and efficient are high or the mould of rounding.
In order to reach above-mentioned requirements; the utility model is achieved through the following technical solutions: it includes upper die and lower die; in patrix or counterdie, be provided with drift with the level; the shape and size that it is characterized in that the drift front end need the hole of chamfering or rounding to match with workpiece; the aperture of step surface after greater than chamfering or rounding; drift front end side and step surface are perpendicular, and the root of drift front end is shaped on the chamfering or the rounding in aperture with the junction of step surface and is connected inclined-plane or fillet accordingly.
According to the aperture chamfering of such scheme manufacturing or the mould of rounding, need only during use workpiece is placed between the upper and lower mould, the drift front end is aimed in the hole of chamfering or rounding, the drift front end enters Kong Zhonghou, when upper and lower mould is closed, because the root of drift front end and the extruding that is connected inclined-plane or fillet of step surface make the aperture of workpiece form chamfering or rounding.Chamfering or rounding are very convenient like this, can finish chamfering or rounding in punching.
Description of drawings
Fig. 1 is the front view of mould when upper and lower mould is closed of aperture chamfering or rounding;
Fig. 2 is the enlarged drawing of a-quadrant among Fig. 1;
Fig. 3 is the partial view of drift head.
Wherein: 1, patrix; 2, counterdie; 3, drift; 4, drift front end; 5, workpiece; 6, hole; 7, step surface; 8, drift front end side; 9, connect inclined-plane or fillet; 10, drift front end face; 11, chamfering or rounding; 12, lower die face.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1, Fig. 2 are the structural representations of the mould of aperture chamfering or rounding.As seen from the figure, it includes patrix 1 and counterdie 2, be provided with drift 3 with the level in the counterdie 2 as shown in Figure 3, the shape and size of drift front end 4 need the hole 6 of chamfering or rounding to match with workpiece 5, the aperture of step surface 7 after greater than chamfering or rounding, drift front end side 8 is perpendicular with step surface 7, the root of drift front end 4 is shaped on the chamfering or the rounding in aperture with the junction of step surface 7 and is connected inclined-plane or fillet 9 accordingly, need the inclined-plane of using of chamfering for the aperture, the aperture needs the fillet of using of rounding.The length of drift front end 4 is less than the thickness of workpiece 5, and drift front end face 10 is shaped on chamfering or the rounding 11 for guiding, and step surface 7 is concordant with lower die face 12.Workpiece hole 6 will be enclosed within on the drift front end 4, after patrix 1 and counterdie 2 closures, will just be pushing formation chamfering or rounding towards following workpiece aperture.Certainly, principle drift 3 also can be arranged in the patrix 2 in view of the above.

Claims (4)

1, the mould of aperture chamfering or rounding; it includes upper die and lower die; in patrix or counterdie, be provided with drift with the level; the shape and size that it is characterized in that the drift front end need the hole of chamfering or rounding to match with workpiece; the aperture of step surface after greater than chamfering or rounding; drift front end side and step surface are perpendicular, and the root of drift front end is shaped on the chamfering or the rounding in aperture with the junction of step surface and is connected inclined-plane or fillet accordingly.
2, the mould of aperture chamfering according to claim 1 or rounding is characterized in that the thickness of the length of described drift front end less than workpiece.
3, the mould of aperture chamfering according to claim 1 or rounding is characterized in that described step surface is concordant with the die face of institute installation drift.
