Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0018] refer to figure 1 , figure 2 As shown, a countersunk hole is set on a thin part 10 and is composed of a hole 1 and a countersunk head 2 on one side of the hole 1. At least one running groove 3 is provided around the hole 1 in the radial direction. The groove 3 runs through both sides of the thin part 10, and the running groove 3 extends radially to the outside of the countersink 2. The running chute 3 is provided with four channels, evenly distributed around the hole 1 .

[0019] refer to image 3 , Figure 4 As shown, as another embodiment of the present invention, the running chute 3 is provided with six channels, evenly distributed around the hole 1 .

[0020] The running trough 3 is used to release the stress generated after punching the counterbore, so that the surfaces on both sides of the thin part 10 remain flat ...

Abstract

The invention discloses a countersunk hole, which is set on a thin part and consists of a hole and a countersunk head on one side of the hole. At least one running groove is arranged radially around the hole, and the running groove runs through both sides of the thin part. , The running trough extends radially to the outside of the countersink. The running trough is used to release the stress generated after punching the counterbore, so that the surface on both sides of the part remains flat and improves the quality of the part.

Description

technical field [0001] The invention relates to a counterbore. Background technique [0002] When punching a counterbore on a thin part, often because the part is too thin, there is nowhere to release the stress, resulting in the uneven surface of the part after punching, which affects the quality of the part. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a counterbore, the special hole shape can release the stress, make the surface of the part smooth, and improve the quality. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized through the following technical solutions: [0005] A countersunk hole is set on a thin part and consists of a hole and a countersunk head on one side of the hole. At least one running groove is arranged radially around the hole. The running groove runs through b...
