The invention relates to a double-station riveting mold for riveting and locking of an opening of a steel barrel, which comprises an upper mold and a lower mold. The upper surface of the lower mold is provided with two riveting bosses, i.e. a large riveting boss and a small riveting boss; and the upper mold is provided with two upper riveting punches matched with the large riveting boss and the small riveting boss on the upper surface of the lower mold. By adopting the double-station riveting mold for riveting and locking of the opening of the steel barrel, punching and extension of two holes on the upper surface of the steel barrel can be completed simultaneously. The problems of the traditional process that the production efficiency is low and two pressing machines are needed for punching can be solved effectively. High-efficiency production and process can be achieved; and the labor and equipment resources can be saved, and the production efficiency can be increased greatly.
Description
technical field [0001] The invention belongs to a punching die for making a steel drum, in particular to a double-station riveting die for riveting and locking the mouth of a steel drum. Background technique [0002] There are two holes on the upper surface of a steel drum, a large hole and a small hole. The large hole is used for liquid in and out, and the small hole is used for drainage or air intake when the liquid is in and out. In the original traditional steel drum manufacturing, two presses were used to rivet and lock the G3 / 4" barrel mouth and the G2" barrel mouth process, which was a waste of man-hours and low production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-station riveting mold for riveting and locking the mouth of a steel drum. Riveting two barrel mouths at the same time by integrating them into one press. This technology effectively solves the problem of low producti...
