Steel ingot foot and manufacturing method thereof

Abstract

The invention provides an ingot foot. The ingot foot comprises a body formed through integrally cold upsetting and punching. The body comprises a flange formed through cold upsetting, an ingot foot formed by extending from the bottom end of the flange and a blind hole formed in the ingot foot through repeated punching, wherein an opening of the blind hole is formed in the top end of the flange, and a boss is formed at the bottom end of the blind hole through punching. As cold upsetting integral forming is adopted, the strength and the consistency of the ingot foot are guaranteed, material wastage is reduced due to the cold upsetting process, the structural strength and the performance of the ingot foot are better than the structural strength and the performance of an assembly ingot foot, and the production cost is low. The invention further provides a method for manufacturing the ingot foot. The method comprises the steps of cold upsetting forming of billet and finish machining and forming of a final product. Basic sizes of the blind hole, the flange and the ingot foot are formed through billet forming, and the requirement for accuracy of all parts is met through finish machining. The ingot foot has the advantages of being clear in labor division, simple in forming step, good in product strength and consistency and capable of greatly reducing the manufacturing cost.

Description

technical field [0001] The invention relates to a textile device, in particular to a steel ingot foot. It also relates to a method for manufacturing the ingot foot. Background technique [0002] At the beginning of the development of the ingot feet, most of the ingot feet were cast iron feet. However, the cast iron ingot feet had the defect of microporous oil seepage and polluted cotton yarn, and were gradually replaced by steel ingot feet. However, the steel ingot feet on the market are usually manufactured in the form of assemblies. Although the manufacturing process is simple, a lot of steel material is lost in the process, and the final assembly of the manufactured steel ingot foot assembly will cause certain errors, resulting in low precision and high cost of the final product. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the invention [0004] The purpose of the present invention is to add...
