First, workers put the template on the steel plate, and then use the plasma cutting machine to cut two steel plates with a thickness of two to three millimeters. Then the workers will paint on the steel plate with hammers to make Niu Lin more artistic. Next, put the steel plate into the oven at 1000 degrees Celsius until the steel plate is red and soft, and then put it into the press. This machine presses the steel plate into the shape of half a cowbell. Workers will also beat the inner surface of the cowbell centimeter by centimeter with a hammer to make the sound quality of the cowbell clearer.
Secondly, in the next step, the two steel plates are combined together and welded at the joint with a welder. Then the worker polished the weld and put the cylinder on the surface of the cow bell. Then he welded a steel handle on the top of the cow to make it easy for the cow to wear. Next, the workers welded a piece of miniature steel inside the cowbell to hang a pendulum for beating the cowbell, and then soaked the whole cow in dilute hydrochloric acid, which made the surface of the cowbell softer and brighter. Then wash off impurities such as hydrochloric acid on the surface of cowbell with clear water, and wait for it to dry a little after cleaning.
Third, workers put cowbells into a pot of sawdust, which can quickly absorb the water on the surface of cowbells. Finally, the workers painted a little acid on the outline of the cow and oxidized it like a steel plate, thus making the cow bell more layered. Such a beautiful cowbell needs superb technology to make. Every cowbell is a work of art. After making it, the cowbell needs to be tested manually before it can be worn on the cow. At this point, the production process of cowbell is all over.
