Forming equipment and processing method of wristband

Abstract

The invention discloses forming equipment of a wristband. The forming equipment is used for forming a gold tube. The forming equipment comprises a machine base, a machine frame fixedly connected with the machine base, a lower mold base fixed on the machine base and an upper mold base fixed on the machine frame; the machine frame is provided with a lifting device for driving the upper mold base to vertically move; a plurality of upper mold cavities are transversely formed in the upper mold base and are provided with lower mold cavities corresponding to the upper mold cavities; the upper mold cavities and the lower mold cavities are symmetrically arranged and jointly form a mold cavity for forming the gold tube; each of the upper mold cavities comprises a necking section and a forming section sequentially arranged from outside to inside; the plurality of upper mold cavities are sequentially arranged; the diameter of the necking section of the latter upper mold cavity is 0.3-1 mm larger than that of the forming section of the former upper mold cavity. With the adoption of the forming equipment, the loss in the processing process of the wristband is very less, so that the purpose of reducing the production cost is achieved. The forming equipment disclosed by the invention can realize automatic production to improve the production efficiency.

Description

technical field [0001] The invention relates to a bracelet forming device and method. Background technique [0002] In the prior art, the processing of gold tubes into tubular parts is through extrusion and grinding, and the grinding process will cause material loss, and this processing method for precious metals will make the processing cost very high . Due to the loss, the dimensional error of the tubular part after processing is relatively large. Therefore, the operator needs to continuously measure during the processing, and the operation is complicated. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art, the object of the present invention is to provide a forming device and a processing method for a bracelet. [0004] The technical solution of the present invention is: a forming equipment for bracelets, which is used for forming gold pipes, comprising: a machine base, a frame fixedly connected to the machine ba...
