Example Embodiment

[0023] Combine figure 1 Figure 3 illustrates a punching method for producing HDMI precision high-definition interface terminals of the present invention, including the following steps:

[0024] (1) Blanking: blanking finished products by punching the pre-processed metal sheet;

[0025] (2) Forming: the blanking product after punching is bent and formed into interface terminals;

[0026] (3) Demoulding: Make the interface terminal out of the stamping die.

[0027] The blanking step is completed sequentially by rough cutting and fine cutting.

[0028] On the pre-processed metal sheet, the center lines of the rough cutting punching hole 1 of the rough cutting blanking punching and the fine cutting punching hole 2 of the fine cutting blanking punching coincide. And the area of ​​the rough-cut punching hole 1 is smaller than the area of ​​the fine-cut punching hole 2.

[0029] The punching die is composed of a matching punch and a die. The punch is composed of an upper die seat, an upper bac...

Abstract

The invention discloses a stamping method for producing precise HDMI (high definition multimedia interface) terminals and relates to a cold stamping die. The invention aims to solve the following problem: pins are easy to bend and even lean against each other during existing interface terminal cold stamping production, thus causing short circuit of terminal products. The stamping method comprises the following steps: (1) blanking: punching preprocessed metal sheets to prepare blanked finished products; (2) forming: bending and forming the punched blanked finished products to prepare the interface terminals; and (3) die releasing: releasing the interface terminals from a stamping die, wherein the blanking step comprises rough cutting blanking and accurate cutting blanking in sequence. The stamping method is especially suitable for producing the precise HDMI terminals.

Description

technical field [0001] The invention relates to a cold stamping method, in particular to a stamping method for producing HDMI precision high-definition interface terminals. Background technique [0002] High-definition multimedia interface HDMI (High Definition Multimedia Interface) is a fully digital image and sound transmission interface, which can be used in set-top boxes, DVD players, personal computers, video games, integrated amplifiers, digital audio or televisions, etc. . In a notebook computer, the HDMI interface is used to transmit lossless video and audio synchronous high-definition digital signals with high-definition display devices such as LCD TVs. [0003] Due to the dense and thin pins of high-definition multimedia interface HDMI, in the cold stamping production of interface terminal products, the pins are bent due to the stress generated by the steel during cutting and blanking, and even adjacent pins are close together, resulting in A short circuit occurs...
