Embodiment Construction

[0017] The present invention will be further described below in conjunction with the drawings.

[0018] Such as Figure 1-2 As shown, the present invention is composed of an upper mold with a punching blade 3, a lower mold with a limiting block 9 and a punching bottom mold 5. The upper mold also includes a blade fixing plate 1, and the lower mold also includes a bottom Mold fixing plate 7. The invention must be matched with a punching machine tool. Before using punching, the mold is closed, and the adjusting screw sleeve 6 is rotated to adjust the gap between the punching bottom mold 5 and the punching blade 3 to be nearly zero. Open the mold, feed in the gold wire, and adjust the limit length to meet the requirements through trial cutting and rotating the adjusting screw plug 8.

[0019] Such as figure 1 with 3 As shown, the blade fixing plate 1 is provided with a clamping hole 1-1 in the center, and threaded through holes 1-2 are provided on both sides.

[0020] Such as figure ...

Abstract

The invention relates to an adjustable fast-replacement type gold grain punching die. The die is composed of an upper die with a punching blade and a lower die with an adjustable limiting device and a punching bottom base. The punching blade is in clearance fit with a blade fixing plate and is compressed through a screw, and fast placement can be achieved. A semicircular groove opening is formed in the cutting edge of the blade and is identical to gold grains in radius. The limiting device is composed of a limiting block, a belleville spring and an adjusting screw plug, and the limiting position can be adjusted by rotating the screw plug. The punching bottom die is in clearance fit with a bottom die fixing plate and is assembled to the bottom die fixing plate through the belleville spring and an adjusting screw sleeve, the clearance between the cutting edge of the bottom die and the blade can be adjusted by rotating the screw sleeve, and meanwhile fast replacement can also be achieved. A through hole is formed in the bottom die, and the hole diameter of the cutting edge is identical to the diameter of the gold grains. The end faces of the gold grains can be free of deformation and burrs, and efficient precise punching with the consistent weight of a single grain can be achieved.

Description

Technical field [0001] The invention patent relates to an adjustable quick-change gold particle punching die, which belongs to the technical field of material molding of processing engineering. Background technique [0002] The present invention is mainly proposed for the manufacture of evaporated gold particles in China. Before the implementation of this technology, common punching and lathe cutting were used. Ordinary punching shears are difficult to adjust the gap, limit and replace the parts. The cost is high. The product has many burrs, tread angles, poor dimensional accuracy, and it is difficult to control the uniformity of single grain weight. Using a lathe for cutting, the production efficiency is extremely low, and there are still a few burrs. Summary of the invention [0003] The technical problem to be solved by the present invention is the manufacture of evaporated gold particles for chip back gold. Before technological innovation, the manufacturing of evaporated go...
