Example Embodiment

[0047] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0048] Such as figure 1 with 2 In the illustrated embodiment, the die for stamping automobile parts of the present invention includes a die body. The die body includes a first part 1, a second part 2 and a third part which are arranged from left to right. Part 3, the first part of the female mold 1, the second part of the female mold 2 and the third part of the female mold 3 are coaxially arranged. The outer diameter of the second part 2 is larger than the outer diameter of the third part 3 of the female mold, and an annular groove 4 is provided between the first part 1 of the female mold and the second part 2 of the female mold and at the periphery of the second part 2 of the female mold.

[0049] A first middle blind hole 5 is opened in the center of the first part 1 of the concave mold. The first middle blind hole 5 extends from...

Abstract

The invention discloses a female die for stamping of automobile parts. The female die comprises a female die body. The female die body comprises a female die first part, a female die second part and a female die third part, wherein the female die first part, the female die second part and the female die third part are coaxially arranged in sequence from left to right. The outer diameter of the female die first part is larger than that of the female die second part, and the outer diameter of the female die second part is larger than that of the female die third part. A first middle hole is formed in the center of the female die first part, and the depth of the first middle hole is larger than the axial thickness of the female die first part. A second middle hole which is coaxial with the first middle hole and communicated with the first middle hole is formed in the center of the female die third part, and the diameter of the first middle hole is larger that that of the second middle hole. The female die has high dimensional precision, and can be used repeatedly and guarantee manufacturing precision and assembly precision of the automobile parts which are manufactured through the female die. The invention further discloses a machining method of the female die. By means of the machining method, the dimensional precision of the female die in a stamping die is high, the female die can be qualified at a time through the production process, and the product rejection rate is low.

Description

technical field [0001] The invention relates to a stamping die, in particular to a die for stamping auto parts and a processing method thereof. Background technique [0002] Due to the limitation of the use environment, auto parts need to have high manufacturing precision and assembly precision. Therefore, the stamping dies used for stamping auto parts also need to have high manufacturing precision to ensure that the manufactured auto parts meet the requirements. [0003] Stamping dies include punches and dies. At present, the method of processing dies generally adopts traditional manual turning, milling and grinding. The processed dies cannot meet the accuracy requirements of each size, making the dies unable to be assembled or used, resulting in The die needs to be processed twice or scrapped directly, which increases the cost and prolongs the production cycle. Contents of the invention [0004] The purpose of the present invention is to propose a die for stamping auto...
