Problems solved by technology

[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 reprocessed or scrapped directly, which increases the cost and prolongs the production cycle

Embodiment Construction

[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 figure 2 In the illustrated embodiment, a stamping die for auto parts of the present invention includes a die body, and the die body includes a first part 1, a second part 2 and a second part of the die, which are arranged from left to right. The third part of the cavity 3, the first part of the cavity 1, the second part of the cavity 2 and the third part of the cavity 3 are coaxially arranged. The outer diameter of the first part 1 of the cavity is larger than that of the second part 2 of the cavity. The outer diameter of the second part 2 of the mold is larger than the outer diameter of the third part 3 of the female mold. 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. ...

Abstract

The invention discloses a stamping cavity die for automotive components, comprising a die main body which comprises coaxially set first die part (1), a second die part (2) and a third die part (3) from the left side to the right side, wherein the outer diameter of the first die part (1) is greater than that of the second die part (2), the outer diameter of the second die part (2) is greater than that of the third die part (3), a first middle hole is arranged in the center of the first die part 91), the depth of the first middle hole is greater than the axial thickness of the first die part(1), the centre of the third die part (3) is provided with a second middle hole coaxial and communicating with the first middle hole; and the diameter of the first middle hole is greater than that of the second middle hole. With higher size precision, the die can be used repeatedly; and the manufacturing precision and assembly precision of the automotive components manufactured by the die can be ensured. The invention further discloses a die processing method, the sizeof the die of the stamping die is accurate and precise by the processing method.The production process is qualified and has low product rejection rate.

Description

Technical field [0001] The invention relates to a stamping die, in particular to a stamping die used for auto parts and a processing method thereof. Background technique [0002] Due to the limitation of the environment in which auto parts are used, high manufacturing precision and assembly precision are required. Therefore, the stamping dies used for stamping auto parts also need to have higher manufacturing accuracy to ensure that the manufactured auto parts meet the requirements. [0003] Stamping dies include punches and dies. The current method of processing dies generally uses traditional manual turning and milling. 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. Summary of the invention [0004] The purpose of the present invention is to provide a stamping die for auto parts,...
