Designated representative map: (1) The representative representative of the case is: the third picture. (2) A brief description of the symbol of the representative figure: 8. If there is a chemical formula in this case, please disclose the chemical formula which best shows the characteristics of the invention. 9. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a tow ball, in particular Refers to a method of manufacturing a trailer ball system using cold forging. [Prior Art] With the development and advancement of science and technology, people's demands for things have become quite delicate and demanding from the old thinking of being able to use them. Only the concept of continuous improvement or innovation has produced new ones. In order to improve the added value of products, the brigade can effectively reduce costs and survive in the fierce market competition. The first picture of the tea photo shows the manufacturing process of using the hot forging tow ball. The manufacturing process of the tow ball is the process of blanking, heating, forging and shaping two surface processing, and finally the finished product is completed in six steps. 'Rather, the hot forging trailer surface to make the financial towel, must first avoid the heating and then forging: and the hot forged trailer material finished stalk cooling, due to the impact of the sturdy thing 'the precision of the work size is not # control, So need to go through the whole
