Abstract
The utility model discloses a plum blossom groove drift, including the drift body, the upper surface of drift body is equipped with bellied plum blossom and dashes the post, the upper surface that the plum blossom dashes the post is equipped with bellied cylindric towards the needle, towards the needle with the plum blossom dashes post integrated into one piece. The utility model discloses an integrative setting is towards the needle on the plum blossom dashes the post, makes the drift can once only dash out the plum blossom groove that has the cylinder hole, uses ordinary cold heading machine just can process out the bolt head that needs, low in production cost, and production efficiency is high.
Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a technical field of fastener drift, especially the technical field of plum blossom groove drift.
[ background of the invention ]
At present, the head of the screw on the market is generally in a straight structure, a cross structure, an inner hexagonal structure, a hexagonal plum blossom structure and the like, wherein the hexagonal plum blossom structure has better skid resistance compared with other structures. In actual production, a cylindrical hole needs to be machined in a hexagonal quincuncial groove of a bolt head, the existing production mode is that the quincuncial groove is punched on the bolt head firstly, then the cylindrical hole is punched, multi-station production equipment is needed, production cost is high, and efficiency is low.
[ Utility model ] content
The utility model aims at solving the problem among the prior art, providing a plum blossom groove drift, can once only go out the plum blossom groove that has the round hole post, use ordinary cold heading machine just can process, low in production cost, production efficiency is high.
In order to achieve the above object, the utility model provides a plum blossom groove drift, including the drift body, the upper surface of drift body is equipped with bellied plum blossom and dashes the post, the upper surface that the plum blossom dashes the post is equipped with bellied cylindric towards the needle, towards the needle with the plum blossom dashes post integrated into one piece.
Preferably, the diameter of the punching needle is smaller than that of the quincuncial punching column.
Preferably, the quincunx punching column and the punching needle are in smooth transition through an inclined plane.
Preferably, the upper surface of the punch needle is provided with an integrally formed conical head.
The utility model has the advantages that: the utility model discloses an integrative setting is towards the needle on the plum blossom dashes the post, makes the drift can once only dash out the plum blossom groove that has the cylinder hole, uses ordinary cold heading machine just can process out the bolt head that needs, low in production cost, and production efficiency is high.
The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
[ description of the drawings ]
Fig. 1 is a schematic structural view of a quincuncial groove punch of the present invention;
fig. 2 is a front view of the quincuncial groove punch of the present invention;
fig. 3 is a top view of the plum blossom groove punch of the present invention.
In the figure: 1-punch body, 2-quincuncial punch column, 3-punch needle, 4-inclined plane and 5-conical head.
[ detailed description ] A
Referring to fig. 1, fig. 2, fig. 3, the utility model relates to a plum blossom groove drift, including drift body 1, the upper surface of drift body 1 is equipped with bellied plum blossom and dashes post 2, the plum blossom dashes the upper surface center department of post 2 and is equipped with bellied cylindric towards needle 3, towards needle 3 with the plum blossom dashes 2 integrated into one piece of post, the diameter that dashes needle 3 is less than the diameter that the plum blossom dashes post 2, the plum blossom dashes post 2 and dashes through 4 rounding off in inclined plane between the needle 3, the upper surface that dashes needle 3 is equipped with integrated into one piece's circular cone head 5.
The utility model discloses the working process:
the utility model relates to a plum blossom groove drift is installed two cold heading machines of a mould with the drift in the course of the work, has plum blossom groove and cylinder hole on the bolt head that this drift punching press was gone out, and one shot forming obtains required bolt head, need not divide the multistation to process, low in production cost, and production efficiency is high.
The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
