Abstract
The invention discloses a counter bore. The counter bore is formed in a thin part, and is composed of a bore and a countersunk head at one side of the bore, wherein at least one discharge slot is formed in the periphery of the bore in the radial direction; the discharge slot penetrates through the two surfaces of the thin part; and the discharge slot extends to the outside of the countersunk head in the radial direction. The discharge slot is used for releasing stress generated after blanking the counter bore, so that the two surfaces of the part are still kept flat, and therefore, component quality is improved.
Description
Technical field
The present invention relates to a kind of counterbore.
Background technology
On thin part during stamping-out counterbore, often the thinnest because of part, stress discharges nowhere, and after causing stamping-out, piece surface is the most smooth, affects part quality.
Summary of the invention
It is an object of the invention to the problem above overcoming prior art to exist, it is provided that a kind of counterbore, special pass can discharge stress, makes piece surface smooth, promotes quality.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of counterbore, is opened on thin part, is made up of the countersunk head in hole and side, hole, radially offer and run hopper the most together around described hole, and described race hopper runs through thin part two sides, runs hopper and radially extends outside countersunk head.
Further, described race hopper at least offers twice, is evenly distributed on around described hole.
Preferably, described race hopper offers four roads, is evenly distributed on around described hole.
Preferably, described race hopper offers six roads, is evenly distributed on around described hole.
The invention has the beneficial effects as follows:
Race hopper, in order to the stress produced after discharging stamping-out counterbore, makes part both side surface still keep smooth, improves part quality.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention, and can be practiced according to the content of description, below with presently preferred embodiments of the present invention and coordinate accompanying drawing describe in detail as after.The detailed description of the invention of the present invention is shown in detail in by following example and accompanying drawing thereof.
Accompanying drawing explanation
Accompanying drawing described herein is used for providing a further understanding of the present invention, constitutes the part of the application, and the schematic description and description of the present invention is used for explaining the present invention, is not intended that inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is a kind of counterbore top view；
Fig. 2 is a kind of counterbore perspective view；
Fig. 3 is another kind of counterbore top view；
Fig. 4 is another kind of counterbore perspective view.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is described in detail.
Shown in reference Fig. 1, Fig. 2, a kind of counterbore, it is opened on thin part 10, it is made up of the countersunk head 2 in hole 1 and side, hole 1, radially offering at least one race hopper 3 around described hole 1, described race hopper 3 runs through thin part 10 two sides, runs hopper 3 and radially extends outside countersunk head 2.Described race hopper 3 offers four roads, is evenly distributed on around described hole 1.
With reference to shown in Fig. 3, Fig. 4, as the another kind of embodiment of the present invention, described race hopper 3 offers six roads, is evenly distributed on around described hole 1.
Race hopper 3, in order to the stress produced after discharging stamping-out counterbore, makes thin part 10 both side surface still keep smooth, improves part quality.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
