Device for batch precise cutting of precious metal standard wire segments and cutting method of device

Abstract

The invention discloses a device for batch precise cutting of precious metal standard wire segments. The device comprises a two-way multi-segment transverse cutting die which comprises a cutting upperdie body and a cutting lower die body; a buffering pad is arranged between the cutting upper die body and the cutting lower die body; one side of the cutting upper die body is provided with a wire inflow hole, and the other side edge of the cutting upper die body is provided with a wire outflow hole along the edge of the cutting lower die body in the opposite direction; the inner side face of thecutting upper die body is provided with upper cutting blades which are provided with upper U-shaped notches, and an upper cutting groove is formed between every two adjacent upper cutting blades; theinner side face of the cutting lower die body is provided with lower cutting blades which are provided with lower U-shaped notches, and a lower cutting groove is formed between every two adjacent lower cutting blades; the upper cutting blades are embedded into the lower cutting grooves, and attached to the lower cutting blades on the two sides of the lower cutting grooves; and the lower cutting blades are embedded into the upper cutting grooves, and attached to the upper cutting blades on the two sides of the upper cutting grooves. The device breaks through the limitation that precious metalproducts in micro weight specifications in the interval of 0.001 g to 0.5 g cannot be subjected to large scale, standard and low cost machining due to technological innovation.

Description

technical field [0001] The invention relates to a cutting device, in particular to a device for batch-accurately cutting precious metal standard line segments and a cutting method thereof. Background technique [0002] As the precious metal physical investment demand market gradually tends to be popularized, small-amount, and fragmented, the initial threshold of investing hundreds of yuan in traditional precious metal physical products is increasingly unsuitable for the new market demand. Small and micro-sized precious metal physical investment products for units, but traditional production methods and production tools cannot be used to process small and micro-sized precious metal physical products, which cannot be accurate and standardized. The production efficiency is low, the consumption is high, and the labor cost is extremely high, resulting in low premiums in the existing market. Small and micro-sized precious metal physical products are basically blank. Therefore, ba...
