Embodiment Construction

[0015] combine Figure 1 to Figure 3 A mold for producing small-sized curved parts according to the present invention is widely used in electronic and instrument products by adopting continuous stamping process to manufacture curved parts such as USB interface housings. The punch consists of the upper die base, the upper backing plate for the punch, the punch fixing plate and the punch used for stamping from top to bottom. The punch is fixed on the corresponding position of the punch fixing plate according to the stamping process sequence. The die is fixedly connected from top to bottom by the lower backing plate, lower die base and die feet, and the die parts that match the punches on the punch are fixed on the corresponding positions of the lower backing plate in accordance with the stamping process sequence. Both punch and die are installed on the punching machine.

[0016] The strip-shaped thin steel strip is located between the punch and the die of the mold. The punch o...

Abstract

The invention discloses a die for producing a small-sized bending part, which relates to a cold stamping die and aims to solve the problem that production efficiency is lowered because the size of the conventional small-sized metal bending part product is difficult to control and the product cannot be smoothly demoulded during production. The die comprises a male die and a female die which are matched, and a columnar bridging die of which the cross section is matched with that of the bending part, wherein one end of the bridging die is movably connected with the female die. The die is particularly applicable to the production of small-sized metal bending parts such as metal shells of universal serial bus (USB) interfaces and the like.

Description

technical field [0001] The invention relates to a cold stamping die, in particular to a die for producing small bent parts. Background technique [0002] The Universal Serial Bus (USB for short) is a serial bus standard for connecting external devices. It is widely used on computers and can also be used on set-top boxes and game consoles. The metal USB interface is usually molded and bent by a cold stamping die. The punch, die and the sheet between the two of the mold produce relative motion to deform and bend the sheet. After the punch and die are separated, the ejector (or slider) on the die pushes the bent piece Roll out, finish molding and demold. The metal USB interface product is small in size and requires high dimensional accuracy. At present, when most companies produce this product, they mostly use sliders to form it, which makes it difficult to accurately control the size. Demolding, and even deforming the USB interface, resulting in reduced production efficienc...
