Embodiment Construction

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

[0018] Such as Figure 1-2 As shown, the present invention is made up of an upper die with a punching blade 3 and a lower die with a limit block 9 and a punching bottom die 5, the upper die also includes a blade fixing plate 1, and the lower die also includes a bottom die Die fixing plate 7. The present invention must be matched with stamping machine tools. Before using the punching, the mold is closed, and the adjusting screw sleeve 6 is rotated to adjust the gap between the punching bottom die 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 by trial cutting and turning the adjusting screw plug 8.

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

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 patent of the invention relates to an adjustable quick-change gold particle punching die, which belongs to the technical field of material forming in processing engineering. Background technique [0002] The present invention is mainly proposed for the manufacture of domestic evaporated gold particles. Before implementing this technology, ordinary punching and shearing and lathe cutting are often used. Ordinary punching shears are difficult in gap adjustment, limit and parts replacement, and the cost is high. The product has many burrs, tread angles, poor dimensional accuracy, and the uniformity of single grain weight is difficult to control. Using a lathe to cut, the production efficiency is extremely low, and there are still a small amount of burrs. Contents of the invention [0003] The technical problem to be solved by the present invention is the production of evaporated gold particles for chip back gold. Before technological innovation, ...
