Description

Technical Field

[0001] The utility model relates to the technical field of fine cadmium spoon processing, in particular to a spinning device for a fine cadmium spoon, and more particularly to a spinning device for a fine cadmium spoon which is a zinc ladling tool for smelting zinc liquid. Background Art

[0002] When transporting and containing smelted zinc liquid, a fine cadmium spoon is used as the zinc ladling tool. The spoon body is generally formed by pressing a 1.2-mm-thick stainless steel plate, and the spoon handle is welded to complete the ladling of the smelted zinc liquid. Generally, the processing method of the spoon body is that a fitter first cuts the material to size with a shearing machine, and then presses it on a hydraulic press by using an upper and lower die closing. This processing method has many limitations. Each time a fine cadmium spoon of a different specification is pressed, different dies need to be replaced on the hydraulic press, and after the upper and lower die closing and pressing, the dies are opened and removed. The pressing efficiency is low, and the labor intensity is high. At the same time, the fine cadmium spoon is made of a 1.2-mm-thick stainless steel plate. Due to the extension property of the stainless steel thin steel plate, wrinkles appear at the edge after die pressing, which affects the use effect and appearance quality, and the material cost is relatively high. Different specifications of fine cadmium spoons need to be made with different specifications of new dies, and the material cost of die making increases, which increases the material cost.
