Rolling equipment and method for making patterns on the surface of precious metal sheets

Abstract

The invention discloses a rolling device for making patterns on the surface of a precious metal piece and a method thereof. The rolling device comprises a machine base with a vertical plate on one side, a loading wheel, a roller assembly and a receiving wheel which are sequentially arranged on the vertical plate are included, the roller assembly comprises a knurling roller and a supporting rollerwhich is located below the knurling roller and is in rolling contact, the knurling roller comprises a roller body and a nickel plate wrapping the surface of the roller body, a concave cavity is formedin one side of the roller body, the concave cavity is provided with a fastening assembly used for fastening the nickel plate, the nickel plate wraps the surface of the roller body, the concave cavityis provided with the fastening assembly used for fastening the nickel plate, and the two ends of the nickel plate are clamped between an upper fastening plate and a lower fastening plate; the precious metal piece is fed into the position between the knurling roller and the supporting roller for patter pressing, production efficiency is high, a metal plate obtained after pattern engraving can be repeatedly used, the effect of reducing cost is achieved, in the pattern manufacturing process, ink does not need to be used, pollution is avoided, and the environment-friendly effect is achieved.

Description

technical field [0001] The invention relates to the field of precious metal handicrafts, in particular to a rolling device and method for making patterns on the surface of precious metal sheets. Background technique [0002] With the current rapid economic development, many people have the hobby of collecting precious metals. One is that they can preserve their value, and the other is that precious metals themselves have collection value. Precious metals on the market are generally made into products with patterns. In the prior art, these patterns are either made by traditional die stamping. The production cost of the mold is high; the mold is easily deformed during use, so the mold needs to be eliminated or repaired after a certain number of uses, which increases the economic cost and time cost; due to the limitation of the mold size, the size of the pressed product is generally limited. It is too small to realize the production of larger-sized products; or the method of p...

Precious metals on the market are generally made into products with patterns. In the prior art, these patterns are either made by traditional die stamping. The production cost of the mold is high; the mold is easily deformed during use, so the mold needs to be eliminated or repaired after a certain number of uses, which increases the economic cost and time cost; due to the limitation of the mold size, the size of the pressed product is generally limited. It is too small to realize the production of larger-sized products; or the method of pasting the process film on the precious metal base layer or ink color printing to achieve the aesthetic effect will easily cause the process film to be dislocated, deformed or Adverse effects such as ink falling off, and existing patterns of similar craft products will not produce pattern transformation effects under natural light
