Problems solved by technology
However, the die structure on the cold drawing machine is fixed, and the steel pipe can only be cold drawn to a predetermined size. Once a steel pipe of a different size needs to be replaced for cold drawing, a different cold drawing die needs to be replaced, which leads to higher production costs. Moreover, the replacement of cold drawing dies wastes manpower and takes up space

The invention relates to a cold-drawing rotating disc for steel pipes. According to the cold-drawing rotating disc, after the steel pipes pass through different horn-shaped through holes in cold-drawing moulds for several times, the diameters of the steel pipes can be gradually decreased so that multiple-time cold-drawing of the steel pipes can be conducted on the cold-drawing rotating disc to complete the working procedure. Besides, the cold-drawing moulds with the different horn-shaped through hole diameters are replaced on through holes in a rotating disc body, thus the cold-drawing rotating disc is suitable for cold-drawing of the steel pipes of different diameters, cold-drawing of the most steel pipes can be completed only through matching of a small number of the cold-drawing rotating discs with the cold-drawing moulds with the different horn-shaped through hole diameters accordingly, in this way, the cost is reduced, the cold-drawing moulds are also convenient to replace, and the space is saved.
Description
technical field [0001] The invention relates to a cold-drawing turntable, which can cold-draw and form light-weight, high-strength solid pipe fittings multiple times in the same turntable, and belongs to the technical field of metal product production technology. Background technique [0002] The domestic automobile industry has been using processes such as thermoforming, welding, shaping, and surface treatment to manufacture special-shaped pipe parts. Its performance and manufacturing quality are significantly lower than those of German, British and American products. The quality of the products is unstable and the service life is short. [0003] Internal high pressure forming technology is a new forming technology invented by the United States and Germany in the 1990s. It was first applied in the manufacture of aerospace satellite launchers, aircraft oil circuit systems and other parts, and was quickly extended to automobiles, rail vehicles and other industries to solve th...
